Latest / Elon Musk Podcast / NASA News Conference on Intuitive Machines' First Lunar Landing
Transcript
- 0:02Good afternoon and welcome to NASA's Johnson Space Center in
- 0:06Houston. I'm NILA for Ramsey with NASA
- 0:09Communications. Thank you for joining us.
- 0:12On February 22nd, Intuitive Machines, as I AM 1 mission
- 0:17softly landed in the South Pole region of the Moon near
- 0:20Mallaport. A named Odysseus.
- 0:24The Lander completed a seven day journey to become the first US
- 0:28soft landing on the Moon in more than 50 years.
- 0:32Joining us today to provide insight on this historic mission
- 0:35and to answer questions, we have Steve Altimas, Co Founder and
- 0:39CEO at Intuitive Machines, Joel Kearns, Deputy Associate
- 0:45Administrator for Exploration Science Mission Directorate at
- 0:49NASA Headquarters in Washington, Doctor Tim Crane, Chief
- 0:54Technology Officer and Co Founder at Intuitive Machines
- 0:59and Doctor Prasan Desai, Deputy Associate Administrator of the
- 1:03Space Technology Mission Directorate at NASA
- 1:06Headquarters. First, we'll start with some
- 1:09initial remarks from our briefers before opening it up
- 1:12for questions. We'll be taking your questions
- 1:14on our phone bridge this afternoon.
- 1:16So if you've joined us today, please plus star one to add your
- 1:20name to the queue and ask your question.
- 1:23We'll now begin with opening remarks from Steve.
- 1:27Thank you, Dillifer. Well, hello everybody.
- 1:29It's reflected before we came into the briefing studio this
- 1:34afternoon that this is the first briefing about being on the
- 1:38surface of the moon for the first time in about 52 years in
- 1:43this room. So that's quite incredible and
- 1:46it's a pleasure to be here. Intuitive Machines, Odysseus
- 1:50Lander landed yesterday at 524 a central time.
- 1:55We did have a stable controlled landing and a safe soft
- 1:59touchdown. I'll give you a little bit of
- 2:01description today about the the state of Odysseus or OD and it's
- 2:06attitude on the surface and what what you can expect from it over
- 2:09the coming days. It's pretty incredible.
- 2:13It's it was a quite a spicy seven day.
- 2:16Mission. To get to the moon and I'll give
- 2:19you some fun facts about how far we've traveled and and how fast
- 2:23we've gone. So just to begin with, the
- 2:26vehicle is stable near or at our intended landing site.
- 2:32We do have communications with the with the Lander.
- 2:36It's from the larger radio astronomy dishes around the
- 2:40world that are part of our lunar telemetry network and to the
- 2:44spacecraft from several of the antennas and two of the radios.
- 2:49So that's phenomenal to begin with.
- 2:51So we're beginning to now that we're on the goon hilly dish in
- 2:55the United Kingdom, we're downloading and commanding,
- 2:58downloading data from the from the buffers in the spacecraft
- 3:01and commanding the spacecraft and trying to get you surface
- 3:05photos because I know that everyone's hungry for those
- 3:07surface photos. But we got some interesting data
- 3:11that gives us a position, an attitude of where the where the
- 3:15Lander is. And I'll explain that in a
- 3:16moment. We have the sun impinging on the
- 3:20solar arrays and charging our batteries.
- 3:23We are providing power to the spacecraft and we're at 100%
- 3:27state of charge. That's fantastic.
- 3:30I talked to you about the communications, and we will be
- 3:33taking an image, hopefully this weekend from the Lunar
- 3:37Reconnaissance Orbiter to find the Lander and pinpoint its
- 3:42location in the South Pole region of the Moon.
- 3:46If you can go to the photo here that we have, this is a photo
- 3:51that I thought you'd find interesting that we'll release
- 3:54to the public here. Here we're flying about 10
- 3:58kilometers over the surface of Schaumburger Crater near the
- 4:01South Pole region of the Moon. We're still about 200 kilometers
- 4:06up, up range from from where our intended landing site is.
- 4:12But here we have a one of our public affairs cameras taking
- 4:16this beautiful image and you see how shadowed and you know
- 4:20undulating the the terrain is and that's important to
- 4:23understand how difficult it is to to land on the surface of the
- 4:26moon. So thanks for that image.
- 4:29Going back, I could say that it was quite phenomenal that if you
- 4:35think about it, we were traveling 25,000 miles an hour
- 4:39and we came down and touched down at about 6 miles an hour
- 4:45with a down range traverse of about two miles an hour.
- 4:49That's walking speed. So that's kind of just an
- 4:53interesting metric for you. We traveled 2 1/2 times the
- 4:57distance to the lunar surface. That's about 600,000 miles due
- 5:02to the trajectory and the number of orbits that we've gone
- 5:05through in doing that and in and in performing that incredible
- 5:10deceleration. Our first of a kind liquid
- 5:14oxygen, liquid methane, additively manufactured 3D
- 5:17printed engine burned six times for a cumulative burn time of
- 5:24over 20 minutes. It's just an incredible
- 5:27performing machine and we're really proud to take that
- 5:29technology to ATRL Level 9. I got to say something about the
- 5:36the team. The OPS teams were cool under
- 5:38pressure for the whole seven days of.
- 5:41It was quite amazing to see him and work real space Cowboys.
- 5:44And you know, we worked through all the difficulties.
- 5:47If you think back from Apollo days, there wasn't 1 mission
- 5:50that went absolutely perfectly. So you have to be adaptable, you
- 5:55have to be innovative and you have to persevere.
- 5:58And we persevered right up until the last moments to get this
- 6:01soft touchdown like we wanted to.
- 6:03Let me just talk briefly about attitude on the surface this a
- 6:07little Lander. I'm going to pretend that's the
- 6:08rock that the Landers leaning on.
- 6:11We think we came down with. Like I said, about 6 miles an
- 6:15hour this way and about two miles an hour this way and
- 6:20caught a foot in the surface and the and the Lander has tipped
- 6:24like this and we believe this is the surface the the orientation
- 6:28of the Lander on the moon. We're getting sun moving this
- 6:32way around the Lander, so the solar arrays are being powered
- 6:36and we believe a little later we'll get Solar Sun on the top
- 6:39deck solar array. The majority of our payloads are
- 6:43all in view and we are collecting science and we've
- 6:46collected science along the way to the moon and I've been
- 6:50downloading that data, in particular, 3 payloads that are
- 6:54positioned on the Lander. They have been active
- 6:57operationally used in this in this mission, the Lane One
- 7:03payload out of Marshall Space Flight Center.
- 7:05We actually assisted us in determining our precise location
- 7:10in space orbit determination we call it using a Doppler
- 7:15measurement that was very useful and and as it was part of the
- 7:20Deep Space Network it augmented our communications from our own
- 7:23commercial network. The other one you've heard about
- 7:26was the NASA Doppler LIDAR from Langley Research Center and we
- 7:30integrated their telemetry stream into our NAV application
- 7:33navigation application and we use that for our power descent
- 7:37initiation. And then finally the one that
- 7:39was very useful was a new technology out of Glenn Research
- 7:42Center and that was the radio frequency mass gauging.
- 7:46And that that instrument really gave us an understanding of what
- 7:50what the propellant tank levels were, which helped us budget the
- 7:54amount of propellant to take us all the way safely to the
- 7:56surface of the moon. So very interesting mission so
- 8:00far as we get more telemetry and turn more things on, we'll be
- 8:05updating you over the coming days of the analysis and the
- 8:09reconstruction of of you know the landing.
- 8:12Tim can comment that on that a little bit today on how we, how
- 8:15we did the power descent all the way to the surface and why we
- 8:18believe in the data that I'm talking to you about today.
- 8:22Yesterday we thought from just to clear up some confusion, we
- 8:26thought we were upright and the reason was that the tanks we're
- 8:30reading this is the X direction and the tanks were reading
- 8:35gravity on the moon. At the fill levels, there were
- 8:37still residuals in the tank and we saw those measurements in the
- 8:40X direction. Well, that was stale telemetry.
- 8:43So when we worked through the night to get other telemetry
- 8:46down, we noticed that in the Z direction, this direction is
- 8:51where we're seeing the tank residual tank quantities.
- 8:54And so that's what tells us with certain fairly certain terms,
- 8:58the orientation of the vehicle and hopefully we'll get a
- 9:01picture here this weekend and and share it with you Milifer.
- 9:05That's all I have. Thank you so much, Steve.
- 9:07Next up we have Joel Kearns. Joel.
- 9:10Hey, thank you, Noah. For first let me congratulate
- 9:13Intuitive Machines for three major accomplishments.
- 9:16The 1st, as Steve said is for having the first a successful
- 9:20soft landing on the moon by the United States since 1972.
- 9:25The second is for being the first non government commercial
- 9:29organization to actually touchdown safely on the surface
- 9:32of the Moon. And the third is we're having a
- 9:35touchdown .80° S latitude much closer to the South Pole of the
- 9:40moon than any earlier AUS robotic or human explorers.
- 9:45Let me give you some of the context for the importance of
- 9:47Intuitive Machines accomplishment on their mission.
- 9:51In 2017, the nation charged NASA to expand our scientific and
- 9:55technical work in the area of the Moon science, technology and
- 9:59human explorers under our Artemis initiative.
- 10:02As part of that, NASA went down the path to to listen to what
- 10:07industry had been telling us for some years, which is that for
- 10:10robotic landing services that we should be able to purchase that
- 10:13from US industry instead of doing it ourselves at NASA for
- 10:17robotic systems. Now NASA is very good at
- 10:21building and operating robotic probes throughout the solar
- 10:23system, but we knew we'd be going back to the moon
- 10:26repeatedly to do science and technical studies and eventually
- 10:29human exploration. So we put into place this
- 10:32commercial Lunar Payload Services initiative or Eclipse
- 10:36to buy and effect the service to bring NASA cargo down to the
- 10:39surface of the moon and have the data from those experiments
- 10:43brought back to Earth by industry.
- 10:46Intuitive Machines is one of the participants in that initiative
- 10:49that's now been awarded 3 service contracts to bring NASA
- 10:53equipment, experiments and cargo down to the surface of the moon.
- 10:57And this was intuitive, Machines first attempt their first
- 11:00mission to the moon carrying our cargo.
- 11:03Now I've talked about all the potential advantages of having
- 11:09industry do this for NASA. The industry had told us years
- 11:13ago that they thought they were technically ready to do it.
- 11:16That they thought if they specialized in doing it, that
- 11:18they could probably do it at less cost and much more
- 11:21frequently and much faster from initial order than NASA probably
- 11:24could, since we would normally build a custom spacecraft for
- 11:27every endeavor. And we've seen that so far in
- 11:30the progress that our CLIPS vendors have made, as they're
- 11:32working down to fly off their first missions in two of the
- 11:36machines, though however, and doing a soft touchdown on the
- 11:39moon has perverted the first real evidence that this is
- 11:42possible to do. It's possible with today's
- 11:45technology, with dedicated engineering and appropriate
- 11:48financial management, to have a private company actually design
- 11:52A spacecraft, develop a mission, buy a rocket, and fly all the
- 11:57way to the moon at soft land on the surface of the moon.
- 12:00Not just an area where we landed earlier decades ago near the
- 12:04equator with the Apollo missions, but in the unusual
- 12:06territory at the South Pole which is the focus of our future
- 12:10human Artemis missions, this is a gigantic accomplishment.
- 12:14On this particular mission we had the company bring 6 NASA
- 12:18science and technology experiments on board down to the
- 12:22lunar surface. They ranged to get to do studies
- 12:26in science in looking at the electron density and plasma on
- 12:32the surface of the moon. Technology studies such as
- 12:35measuring a rocket plume impingement during landing,
- 12:39navigation studies on the way to the moon down to the surface of
- 12:42the moon, laser ranging fuel quantity as other investigations
- 12:48and it's and interesting enough when we started this we had put
- 12:51together a list of different instruments and payloads that
- 12:55the commercial lunar payload services companies could
- 12:57volunteer to take down to the surface of the moon.
- 13:00And intuitive machines pick the complement of five payloads
- 13:04which we later augmented with the radio frequency mass gauge
- 13:07fuel measurement experiment. And intuitive machines pick the
- 13:10number of payloads and experiments from NASA to to
- 13:14bring down which is Steve Widdell greatly benefited them
- 13:17during the execution of their mission.
- 13:19So at this point today is Intuitive machines looks to make
- 13:23sure they understand the status of the Odysseus vehicle.
- 13:28We are already looking back at scientific and technological
- 13:31data that we accumulated during the transit out to the moon
- 13:35during the deorbit operations, and we're looking forward to
- 13:37getting even more data as intuitive machines figure
- 13:41finishes the checkout of Odysseus now.
- 13:44In doing so, we knew at NASA when we went out to gather this
- 13:49by Commercial Services that we had these great potential
- 13:52benefits, but we also had risks. We knew, for example, no one had
- 13:56previously done this. We knew we were asking industry
- 13:59to do an incredibly difficult thing to do to go from those
- 14:02high speeds of orbital velocity all the way down to the very
- 14:06slow speeds at A to get to a particular position on the moon
- 14:09where we wanted them to land and intuitive machines
- 14:12Accomplishment for this actually shows everyone that this is this
- 14:16approach will work and we look forward to using it over and
- 14:19over in the future. Nullifer.
- 14:23Thank you so much. We'll now hand it over to Tim.
- 14:27Thank you, Nullifer. Very excited to be here today.
- 14:30They they told me to smile before the the press conference
- 14:33and I can't help but smile anyway because we landed on the
- 14:35moon a little bit about Odysseus.
- 14:38Odysseus is a mostly autonomous vehicle.
- 14:41Our operations crew would monitor the vehicle during
- 14:45flight, We'd provide some trajectory updates, parameter
- 14:48updates, and that's what got us into lunar orbit.
- 14:51The lunar descent is different though.
- 14:53During orbit we would prepare for maneuvers.
- 14:56We'd watch the maneuver and then know that we had time to recover
- 14:58afterwards and replan for the next stage.
- 15:00But lunar powered descent is the end game.
- 15:02There is no after. You're either successful or you
- 15:05fail. And so the last Rev around the
- 15:07moon, we buttoned up any last minute changes we wanted on the
- 15:11vehicle, and there were a few that we may talk about today,
- 15:14and basically the vehicle disappeared behind the far side
- 15:18of the moon. We have lost the signal for 25
- 15:20minutes. Everybody got up and went to the
- 15:23bathroom. There was nothing to do but wait
- 15:25for the signal to come back on. It was amazing how quickly we
- 15:29adapted to continuous communications during transit to
- 15:33regular losses of signal being a part of our life because we're
- 15:36circling the moon. Once we came up around the North
- 15:39Pole of the moon, we were in a polar orbit.
- 15:41The vehicle was completely autonomous.
- 15:44We watched as the onboard systems pointed our cameras to
- 15:47the moon. We processed over 10,000 images
- 15:50onboard with our own machine learning algorithms to manage
- 15:54the speed of the vehicle and the guidance system decided based on
- 15:59the propulsion system are available thrust levels, orbital
- 16:03velocity and distance to the target near the South Pole.
- 16:07When the right time to turn the engines were were that's power
- 16:10descent initiation and the engines came on approximately 13
- 16:14minutes before landing. We were at full thrust for what
- 16:17we call Braking 1. Basically, we were trying to
- 16:19slow down from approximately 3600 mph to something more like
- 16:2430 mph near the landing site That's breaking one the vehicle
- 16:28performed Florida State. Our our main engine thrust was
- 16:32good. Our thrust control was perfect
- 16:35engine performance. It has exceeded expectations in
- 16:38many ways and flight control my my personal background kept the
- 16:43vehicle pointed exactly where it was supposed to go for the
- 16:45entire burn. We monitored down until a pitch
- 16:49over event so early in the trajectory.
- 16:53The vehicle is basically flying sideways with respect to the
- 16:55moon and we're flying in One Direction and the engine is
- 16:58slowing us down to take that velocity out of the vehicle.
- 17:02Once we get within a kilometer of the landing site, however,
- 17:05the vehicle goes into what we call a pitch over and this
- 17:07brings another set of cameras into alignment with the landing
- 17:12site. At that point we lost calm,
- 17:14which we knew we would do because we switched from one set
- 17:17of antennas to another and then we regained communications all
- 17:20the way until approximately 200 meters above the landing site.
- 17:26Then there was a tense moment where we did not have regular
- 17:29communications, but our dedicated radio and ground
- 17:33operations crew found the signal, and within an hour or so
- 17:37we were getting the first data down from the surface of the
- 17:39men. I could not be prouder of our
- 17:41operations team and our engineers for putting together
- 17:45Odysseus, which was a marvelous machine, And to look at the moon
- 17:50every night now and know that we have new hardware there that we
- 17:54had a hand in building in our lifetime, something I couldn't
- 17:56say before. It really was a a magical,
- 18:00magical day. Thank you.
- 18:03Thank you so much, Tim. And now, finally, we'll hand it
- 18:05over to Prasan. Thank you.
- 18:09So first and foremost, congratulations to Intuitive
- 18:12Machines, an amazing successful landing success story.
- 18:17You know, one of the things that we from a technology and space
- 18:20tech want to do is we want to go with repeated access to various
- 18:24parts of the solar system to do this tech demonstration.
- 18:27Because in our view technology drives exploration.
- 18:30And we had a number of experiments on this technology
- 18:34demonstrations on this Lander and one was called to be used
- 18:38operationally. And I'll talk a little bit about
- 18:40that, but that this aspect of a successful landing really allows
- 18:45to pointing on to what Joel said is repeated access to the lunar
- 18:49surface. We have a slew of technologies
- 18:52we want to demonstrate as well as many science certificate
- 18:54instruments that we want to send for understanding the lunar
- 18:59environment. And by having a successful story
- 19:02like Today, Yesterday that happened, it allows us for
- 19:06setting up the next set of projects that we want to fly and
- 19:10demonstrate right. One of the things that we wanted
- 19:15to do is trying to do as much as possible testing on the ground,
- 19:19but that only gets us to a certain technology readiness
- 19:22level, which is typically TRL 5, sometimes six.
- 19:25What that means is we're we're not quite in the environment
- 19:29that we want to be in. And so This is why we want to go
- 19:31and experiment in space or on a lunar surface, wherever it
- 19:34happens to be. The the one of the big
- 19:38technology demonstrations on on this landing was the navigation
- 19:42Doppler Lidar. We were hoping through the test
- 19:45of flying on this mission was to get it to TRL 6, which is the
- 19:50relevant environment, the lunar environment.
- 19:52However, with the successful ingestion of it during landing,
- 19:56we were able to get a operational system now TRL 9,
- 20:00which is it's ready to be used from now on right as opposed to
- 20:03further testing. This wasn't totally by accident.
- 20:07The teams at NASA Langley Research Center that helped
- 20:10develop this technology did a lot of development over the
- 20:13years, as well as working with intuitive machines to see about
- 20:17ingesting this data if necessary.
- 20:20Fortunately, all that hard work came to bear yesterday when
- 20:24there was a technical issue and the teams decided that hey, it
- 20:28was best to try to do the switch and rely on this tech
- 20:32demonstration. Everything we understand from
- 20:35the telemetry we received, which is limited to this point until
- 20:38we get all the data back, that the technology performed Florida
- 20:41State better than expected performance.
- 20:45It acquired range and velocity data well above the required 5
- 20:49kilometers altitude as it's descending.
- 20:53And the reason why we need this data for successful landing is
- 20:56as Landers come down, we would ideally like to have them come
- 21:00straight down. But because there's errors in
- 21:03the all the operations of the system, you wind up being a
- 21:06little bit going laterally going there.
- 21:11This measurement is really to try to get an understanding of
- 21:13that lateral motion so that the system can counteract that and
- 21:17zero out that lateral motion to come down straight down.
- 21:20So you need these type of measurements to make that
- 21:22happen. This is one set of technologies
- 21:24that allows to do that. There are a slew of other ones
- 21:27to make the landings even more reliable and safer that we hope
- 21:31to demonstrate on future landings.
- 21:33And so having this successful landing today allows us to gear
- 21:36up and get ready to do more of this going forward to enable the
- 21:41Artemis endeavor of repeated access to the surface and
- 21:45eventual landing of humans on the on the surface and and
- 21:49sustained presence on the surface with infrastructure
- 21:52laying it down. And so this is the first step in
- 21:55allowing for that and a great day for allowing us to get ready
- 22:00for more to come as we go forward.
- 22:03Thank you, Prasan, and thank you to our briefers for those
- 22:06initial remarks. We'll now open it up to
- 22:08questions. Again, if you've joined us on
- 22:10the line today or on our phone Bridge, please press * one to
- 22:14submit your question. Once your name is called, please
- 22:17state to whom you'd like to direct your questions.
- 22:21Once your question has been answered you, you will be muted.
- 22:24But if your question has already been answered, you will push
- 22:27Star 2 to withdraw it. Let's open our phone bridge.
- 22:31First up, we have Gina Sinceri with ABC News.
- 22:34Gina. Question is for either Steve or
- 22:39Tim. What was your Hail Mary moment
- 22:41during that where you went? We think we can make.
- 22:44This work and we just made it work.
- 22:46What was? What were those moments?
- 22:47Or were there more than one? Well, I think there were several
- 22:52of those moments. Like I said, it was a spicy
- 22:54mission. I'll let Tim comment a little
- 22:56bit, but you know the idea to pull the range telemetry from
- 23:02the the, the NASA Doppler Lidar was interesting and change out
- 23:08the laser range Finder call outs in the navigation application.
- 23:13All that was very straightforward to go calculate.
- 23:16Part of that was put in the table, but part of that had to
- 23:20mean that we had to rewrite the navigation application software.
- 23:25And when you do that. To upload it to the vehicle you
- 23:29actually have to stop guidance navigation and control.
- 23:34And when we ran that in the simulation and we ran that on
- 23:37the flat sat, it did not like being rebooted like that.
- 23:42That's software and we saw the guidance drift way off.
- 23:45We saw a lot of helium usage and and that was very sporty.
- 23:50So I think in a very time, crunch time, getting ready for
- 23:54power descent, we had to work feverishly to get that sequence
- 24:00of events, almost like Fred Hayes in a in a in Apollo 13.
- 24:04We're trying to figure out the sequence of events to
- 24:07reinitialize the software, in particular, reinitialize
- 24:11navigation. And so that was done in a very
- 24:15sporty way and it was brilliantly executed by the
- 24:18team. And so that was the one that had
- 24:21us all biting our nails just a little bit, because once you
- 24:24start power descent, there's no going back like Tim said.
- 24:28Tim, do you have another one? Yeah, there there was.
- 24:32I I will say on that one a parallel effort for sure.
- 24:35So we had one team rewriting the code, we had one team testing
- 24:38procedures and then another team once the code was written
- 24:42pushing it up on the vehicle moving into place.
- 24:44That synchronization came down to a Florida State executed
- 24:49reboot of the navigation system that allowed us to successfully
- 24:52land. So that was exciting.
- 24:54Another exciting moment we had after our TCM one our trajectory
- 24:58correction maneuver we discovered that our engine
- 25:01pointing geometry had an error in it and we had to study that a
- 25:07bit and we found the the reason why we had a geometry linkage
- 25:12that was a little bit different than we expected.
- 25:14Very difficult to test how that linkage to the main gimbal would
- 25:18respond under full thrust in space.
- 25:20And so we were able to use flight data to correct that.
- 25:23But that was another area where we had to patch the software to
- 25:26put that correction in place. And you know, we became very
- 25:29proficient at it. I will say, and you hear this in
- 25:32the space industry a lot that we stand on the shoulders of
- 25:35giants. The work we were doing was built
- 25:38upon work people had done before us.
- 25:42NASA score flight software is a big part of what we do on the
- 25:45flight vehicle and it has a lot of the capabilities to reload
- 25:50and reinitialize software built into it.
- 25:52And we were able to take advantage of that because of the
- 25:54foresight that people who had done space missions before had
- 25:57invested in in that piece of technology and we used it to
- 26:01great effectiveness going forward.
- 26:05Great. Thank you.
- 26:06Next up, we have Marsha Dunn with The Associated Press.
- 26:11Hi. My questions are for you, Steve.
- 26:14What's your best guess for how close you are to the targeted
- 26:18touchdown area? And you said a lake caught the
- 26:22surface. Do you think the Lander came in
- 26:25builded and it's to catch a lake like that, put it as caught on a
- 26:29rock, and then belly flopped? And do you think Odysseus was
- 26:33ever upright, even for a moment or two, or do you think it just
- 26:36landed on its side from the ghetto?
- 26:37Thanks. Well, thank you Marsha for that
- 26:41question. We are reconstructing with the
- 26:45data that we get, what we think happened.
- 26:49My theory is just a theory until we get an actual picture and see
- 26:54what happened. But if you pass me the model,
- 26:56Tim, I'll show you here is if we're coming down, we came down
- 27:01a little bit faster. We were supposed to come down at
- 27:041m per second, which is about two miles an hour, and we're
- 27:07supposed to null the lateral velocity, which was was supposed
- 27:13to be 0, and we're coming straight down.
- 27:14We had about two miles an hour going this way.
- 27:17And so if you're coming down at six miles an hour is what we
- 27:20think, and moving 2 miles an hour and you catch a foot, we
- 27:25might have fractured that landing gear and tipped over
- 27:27gently. Like I like I said, we have to
- 27:31go look at when the main engine cut off was to see if the main
- 27:34engine had any coupling effect to that or not.
- 27:37I can't tell you for sure. It'd be good to see the health
- 27:39of the landing gear and see how that all looks.
- 27:42And so it'll be a few days before we get all of that put
- 27:45together and reconstructed. That's an action I've already
- 27:47given the team and I look forward to the answer to help
- 27:50inform our future flights. I can add to that that after
- 27:55pitch over we have a hazard relative navigation system that
- 27:58generates measurements at 1 Hertz.
- 28:00This is our optical processing and we generated 84 measurements
- 28:05and process 79 of those. So 84 is important because we
- 28:08have an approximately a 122nd timeline from pitch over to
- 28:12landing. So the fact that we generated 84
- 28:15accounts for a portion of that timeline, they're not
- 28:17necessarily continuous. The fact that we process 79 of
- 28:20them and they were accepted by the common filter that we have
- 28:23in our software means that there was very good agreement between
- 28:26the inertial measurement unit and our our camera velocity
- 28:30measurement and the NDL navigation Doppler lighter on
- 28:33board. With those all in agreement that
- 28:35means we had roughly 90 seconds out of 120 seconds guaranteed
- 28:40stable flight coming in. So we were very close to the
- 28:43vertical phase. We don't have the data from that
- 28:46interval yet. And so we're waiting to see what
- 28:48that is. But that's a really good
- 28:49indication that we were in stable control and vertical at
- 28:52the time we touched down. Thank you.
- 28:57Bill Harwood with CBS News. Hey, thank you very much.
- 29:02I think this is for Steve. How do you guys know it's
- 29:05resting on a rock as it were and not on its side?
- 29:08In other words, how many degrees of vertical did your hike
- 29:11readings lead you to think if if you even got a number like that?
- 29:15And are there any payloads on board that simply cannot work in
- 29:19the current orientation? Thanks.
- 29:22Well, I'll let Tim address part of it.
- 29:26But our reconstruction by based on how much power we're getting
- 29:31off of this solar array says that it that it has to be
- 29:35somewhat elevated off the surface horizontally.
- 29:38So that's why we think it's on a on a rock or the foot is in a in
- 29:42a in a crevice or something to to get to hold it in that that
- 29:47attitude. Fortunately for most, most of
- 29:52the payloads are exposed to the outside above the surface that's
- 29:58down the the, the panel that's down towards the surface.
- 30:01That panel only had a single payload on it and it's not an
- 30:06operational payload, it's it's a static payload.
- 30:09And that one, we're still going to try to take a picture of that
- 30:12payload if we can. And that would meet those
- 30:15objectives of taking a photograph of of that art cube
- 30:19that's in the on that panel and that one that's pointed towards
- 30:23the surface of the of the moon. So we're going to try to
- 30:25download all the pictures and see if we got got that picture
- 30:28in view. Tim, any more insight?
- 30:31We also have some inertial measurement unit data.
- 30:33We've turned a lot of the the flight instrumentation off on
- 30:36the vehicle for power management purposes.
- 30:38But before we did we were able to get some packets and measure
- 30:41lunar gravity and most of that lunar gravity was in the Z
- 30:45direction on that model which is up along fairly close to level.
- 30:51So there is something whether we run into a slope, which would
- 30:54also explain a tip over if there's more slope than than we
- 30:56anticipated at touchdown. So the inertial measurement unit
- 31:01gives a very strong indication that this is up and and those
- 31:07sensors are very, very exquisite.
- 31:09So it's a confirmation of what we're seeing from the tanks.
- 31:13Exactly what the material is that's underneath the Lander is
- 31:16something we hope to get some imagery from over the next
- 31:19coming days and and find out more.
- 31:21Where is eager to see those images as the public is.
- 31:25Yeah. And and I would add in terms of
- 31:27the technology payloads, we've already gotten data along the
- 31:30way to say they've been successful, right.
- 31:32So the radio frequency mass gauge has been working since
- 31:35long, you know, as soon as we got into our low Earth orbit and
- 31:38going on the way. So we've gotten data all along
- 31:40that way as well as during the descent which we're still
- 31:43waiting for telemetry on that. The navigation Doppler or LIDAR,
- 31:47we got that real time going down.
- 31:49So we know that worked very well and successful aspect of it,
- 31:51right, The scalps, the stereo cameras, we're waiting for the
- 31:55pictures to come back there, but you know everything else seems
- 31:58to be working very well. So we anticipate that that
- 32:00worked well during the descent as well and just waiting for the
- 32:04data to come back to, to analyze to see how that went.
- 32:07So a lot of the payloads have already been successfully
- 32:09demonstrated. Yeah, I know.
- 32:11This is Joel. What I'd say is that in addition
- 32:13to what Prasad and Tim said about the fact that so much data
- 32:17was acquired during transit out to the moon, long lunar Warburg
- 32:21and descent, Of course we'll evaluate if there's any
- 32:23particular measurements that we can take because of the vehicle
- 32:27configuration, but in general, we expect to get a lot of data
- 32:30and a lot of measurements from the instruments, both science
- 32:32and technology. Yeah, I have an add to that too.
- 32:35You know, the NDL is a perfect example of a problem solved.
- 32:38But the radio frequency mass gauge was also something that we
- 32:42used for a problem avoided. We had a temperature sensor on
- 32:45one of our tanks and we fly. Cryogenic fluids are very, very
- 32:49cold for propellant and a temperature sensor was
- 32:53recording, reporting back colder than we had anticipated.
- 32:57Well, that could have been indicative of a leak.
- 32:59And so we were beginning to spin up some contingencies.
- 33:02Well, what if we have a leak, What do we do?
- 33:04But because we had the radio frequency mass gauge, we're able
- 33:07to confirm that our tank masses were stable and we just had a
- 33:11little bit of an anomalous sensor reading and that avoided
- 33:14a problem and we didn't spend more energy going through that.
- 33:17So that technology is one that maybe isn't quite as dramatic as
- 33:21a as a Late Orbit software reboot, but nonetheless gave us
- 33:26confidence going through the mission.
- 33:29Great. Thank you so much for your
- 33:31insight on that. Next up we have Ken Chang with
- 33:33the New York Times. Ken.
- 33:36Yes, hi. Thank you.
- 33:37I was wondering I guess for Tamara and Steve for a TikTok of
- 33:42what happened after lunar insertion.
- 33:45It looks like the orbit is lower than what was in the press press
- 33:49kit and then you had another burn that evening and then you
- 33:55avoided the DOI burn and and then you had it, it moved up to
- 34:00launch of the landing time. So I was wondering what the very
- 34:03orbits were and how that affected the landing time.
- 34:07And also, when did you find out that you had a bomb based
- 34:09alternator? I missed the last part.
- 34:13I'll start with the first part. Kenneth, do you want to ask the
- 34:16last part again? When did you find out that you
- 34:21had a laser altimeter? Yeah.
- 34:25OK. Laser altimeter.
- 34:27So the first part of the question was about the lunar
- 34:29orbit insertion and what happened after that, right?
- 34:34If I understand your question right, well, we were having some
- 34:38difficulty with communications around the world communicating
- 34:42from the different configurations and the different
- 34:45dishes that we had around the world up to our radios.
- 34:49And we have Poisonics radios and Talus Alinea radios and some of
- 34:55those that Talus Alinea radios have a range beacon and we have
- 34:59a frequency that we know, a carrier frequency that we're
- 35:02operating on. And some of the dishes were
- 35:04smaller around the world. So in certain parts of the world
- 35:07we had a weaker signal and we would lose that carrier lock.
- 35:11And when that carrier lock goes down, you can't get a good orbit
- 35:16determination. And there was a shift in the
- 35:18ranging beacon. So that shift and that turn
- 35:20around ratio in the ranging beacon is such that you had some
- 35:25inaccuracy, we had some inaccuracy.
- 35:28So we got the best data we could possibly get going into our
- 35:32lunar orbit insertion burn. But what we found was that was
- 35:35slightly elliptical. Actually it was elliptical, not
- 35:39highly elliptical, but it was elliptical orbit And so we were
- 35:41not comfortable necessarily with our the proximity to to, to the
- 35:48to the South Pole area. We were a little too close for
- 35:50our own comfort. So we decided to come in and do
- 35:53a a a raise of our of our periloon position.
- 35:58And we did that very quickly, autonomously and put us in a
- 36:01safer configuration for the mission and be prepared.
- 36:05And that burn we did in such a way that it eliminated the need
- 36:09for a de orbit insertion burn, very small burn before we did
- 36:14power descent. When we were looking at our
- 36:20position around the moon, we decided to take a laser range
- 36:24Finder, power it on and ping the surface to see how close we were
- 36:28because we're having trouble with this orbit determination in
- 36:31this Doppler measurement that we're trying to get.
- 36:33And we saw that that laser didn't fire and what we found
- 36:37was that there's a safety enable switch because it's not an ISAFE
- 36:42laser. That safety enable switch is in
- 36:46the box and was not disabled. So it's like having a a safety
- 36:51on a on a on a on a firearm, it's it's for ground processing
- 36:56and that was an oversight on our part.
- 36:58And so those laser range finders could not be turned on and we
- 37:02couldn't manipulate that enable switch or disable switch with
- 37:06the software. And so those range finders had
- 37:09been tested and would have worked if we'd had caught that
- 37:13oversight and remove that enable before or disable before flight.
- 37:18So I think that got your question.
- 37:20Tim, anything to add on that? No, that's right.
- 37:22I think the key thing was we have an incredible flight
- 37:25dynamics team who were able to determine that from the orbit we
- 37:29were in, we could raise Paralun with a lunar correction maneuver
- 37:34that they had built in with the foresight to trim the orbit.
- 37:36If we had some unexpected conditions and it basically put
- 37:39us into our descent orbit about four or five Revs before we we
- 37:44nominally would have done that. But the orbit still phased over
- 37:47the landing site in the right way and gave us a great
- 37:49opportunity to execute power descent.
- 37:54Thank you so much for that Lauren Grush with Bloomberg.
- 37:59Hi. Thank you so much for taking my
- 38:01question. I think this might be for Steve
- 38:03or Tim. I'm curious if you've been able
- 38:05to determine if the tipping damaged the Lander at all based
- 38:10on the rock that it's leaning on.
- 38:11Is there any concern of further degradation because of the
- 38:15position that it's in? Thanks.
- 38:18Well, again Lauren, we're hopeful to get pictures and
- 38:21really do an assessment of the structure and assessment of all
- 38:24the external equipment. I we we are hopeful that the top
- 38:31deck solar array is not damaged and that as the sun comes around
- 38:35the Lander will be able to get some power generation from the
- 38:38top deck solar array which which is now vertical.
- 38:42And so we'll see what that means.
- 38:44But so far we have quite a bit of operational capability even
- 38:49though we're we're tipped over and so that's that's really
- 38:53exciting for us and we we're continuing the surface
- 38:55operations mission as a result of it.
- 39:00Thank you. Next up we have Andrea
- 39:03Linefelder with the Houston Chronicle.
- 39:05Andrea. Hi, these questions are for Tim
- 39:09Crane, that final orbit you took.
- 39:14I just want to make sure that was specifically to implement
- 39:16the software path to use NASA's LIDAR tech demo for landing.
- 39:20Also, Tim on Twitter or excuse me, X, you mentioned a big role
- 39:24maneuver. Was this part of the plan?
- 39:26If not, what caused the role maneuver and did that create any
- 39:28complications? And finally, I was hoping you
- 39:30could walk us through some of the communication issues
- 39:32experienced right after landing. Was it difficult to get a signal
- 39:35because it was at an angle or was it other challenges related
- 39:39to being unstoppable? Thank you.
- 39:40Thanks, Andrea. I did not catch the first part
- 39:42of your question. Could you, could you repeat
- 39:44that? Sorry, the first part was you
- 39:48know that final orbit that you took that kind of pushed back
- 39:51the landing, Was that specifically to implement the
- 39:53software patch that that helps you land with the NASA's LIDAR
- 39:57tech demo? Yes, OK.
- 39:59Thanks. It was we were we were in good
- 40:02position to land at approximately 3:30.
- 40:05But the the procedures that that Steve was talking about, what
- 40:09order do we bring down the, the flight control, the guidance, do
- 40:13we inhibit RCS? How do we do that in such a way
- 40:16that there's no unexpected consequence on the vehicle?
- 40:18For example, if we turned off guidance navigation and control
- 40:22but didn't turn off the RCS control valves, they could
- 40:26listen to noise on the computer instead of controls to zero, and
- 40:29we could open up the valves and and lose control.
- 40:32So we were very, very deliberate about working through in what we
- 40:35call a flat sat, which is basically the spacecraft
- 40:38equipment laid out in a lab driven by a simulation.
- 40:41We were very deliberate about working that procedure so that
- 40:44when we shut the software down, we could bring it back up
- 40:47safely. There was no harm to the
- 40:48vehicle. We had the patch ready in time
- 40:50for the first landing attempt. We hadn't come to a satisfactory
- 40:54procedure yet and we had to get it right.
- 40:56And so Steve and I conferred. It would be a little bit more
- 41:00fuel to catch the, the, the OR bort once around.
- 41:04But again, our flight dynamics and automation team had written
- 41:07software that gave us a great amount of flexibility to control
- 41:11Odysseus. And we're really at a special
- 41:13time in our lunar program and intuitive machines where most of
- 41:16our operators are also the subject matter experts who built
- 41:19these systems. So we had incredible insight
- 41:21what was going on. We had great confidence we can
- 41:23make this work, but we needed a little bit more time.
- 41:25And so we made the call to abort once around and implemented the
- 41:30patch at that time so that when we had that final orbit we were
- 41:33in high confidence of landing the role maneuver.
- 41:38At the end we had made some decisions.
- 41:41You know every, every vehicle has a mass limit and you're
- 41:44trying to optimize performance versus mass.
- 41:47We had flown a vehicle with fixed antenna and in order to
- 41:51fly with fixed antenna we had to look at what our, our landing
- 41:54orientation was at the South Pole.
- 41:58We landed. In fact you'll see in this model
- 42:01there's white, white paint on on some surfaces and and black
- 42:04paint on others. That's because we were going to
- 42:06land on the South, near the South Pole, and the sun was
- 42:09going to illuminate the solar arrays, as you can imagine, and
- 42:12then also these white surfaces to reject heat.
- 42:15But on the other side we have the cold side, and it gets very,
- 42:19very cold if you're not in direct sunlight on the moon.
- 42:21So we painted that black to catch reflected light off the
- 42:23moon and warm them up. So as we were coming down, we
- 42:30wanted our navigation cameras pointed to the ground.
- 42:33Then we wanted our navigation ground cameras pointing to the
- 42:36ground after we pitched over. But in landing, we had a planned
- 42:42roll maneuver to bring our antennas to face the earth, and
- 42:45so in order to accommodate that we had a planned roll maneuver.
- 42:48It was not unexpected that the roll maneuver would occur.
- 42:53It was also expected that there would be a loss of
- 42:55communications as we switched from our 1-2 antenna pair to our
- 42:593-4 antenna pair. Thank you so much for that.
- 43:04Next up we have Chris Davenport from the Washington Post.
- 43:07Chris. Hey, thanks everyone.
- 43:10For Tim and Steve, just regarding that audible you had
- 43:14to make up and I want to see if I can come down to some of the
- 43:17chronology to get a sense of how the day unfolded for yesterday.
- 43:20About what time is it that that you realize that that that laser
- 43:24range Finder wasn't working and then did you immediately know
- 43:28that you could go to the MDL system was just something you
- 43:31had planned on as a contingency or did you kind of make this up
- 43:36on the fly and decide work on it, you know, in real time
- 43:40yesterday? Thanks.
- 43:41I'll I'll start and Tim will add a lot of color to this because
- 43:46this one, this one was like Gina asked was the Hail Mary issue.
- 43:52When we went around the night before and we made that laser
- 43:58range Finder measurement, it looked like the laser fired, we
- 44:03got an enable in the data, but when we did a deeper analysis
- 44:07analysis of it, it was it was not actually fired, it was an
- 44:12error in the telemetry. So when we dug into it, we that
- 44:17morning, this was the morning of landing, we called MDA and asked
- 44:22them what they thought about it and could we convert that
- 44:26physical enable switch to a software change to command that
- 44:31switch. And they indicated no, there's a
- 44:34physical cut out for this and not a software driven cut out
- 44:40for this. So we now I get into the control
- 44:44room. I can laugh about it now.
- 44:46And Tim was on console as the mission director and I said,
- 44:50Tim, we're going to have to land without laser range finders.
- 44:52And his face got absolutely white because it was like a
- 44:56punch in the stomach that we were going to lose the mission.
- 44:59And we went around and we said what are we going to do?
- 45:01We started to hack into the OS, the operating system of the
- 45:05laser range Finder to see if there was a way we could trick
- 45:08it some way. We thought about running a
- 45:11simulated table of the power descent phase and like predict
- 45:15with like some parameters how we might land and there's just way
- 45:20too much variables, way too many variables in that running a
- 45:24simulation table in against the real world situation.
- 45:29So that wasn't going to get work.
- 45:30And so Tim and I were walking through the halls and trying to
- 45:33find the experts. And he came up with the idea
- 45:36that says, why don't we just Plumb the high beam laser and
- 45:41the low beam laser from the NDL into the registers for the HRN
- 45:47laser range Finder and the TRN laser range Finder.
- 45:50He came up with that while we're walking down the hall in a
- 45:53hurried way. And it only would work if we
- 45:56ingested the range measurement in the NAV application.
- 46:01And we had done that because we had worked with the team at
- 46:04Langley for so long with the NASA Doppler Lidar that we were
- 46:07able to have that instrument in shadow mode to give them better
- 46:13quality data. And because it was in shadow
- 46:15mode, we had that measurement in the navigation application and
- 46:20it was just a brilliant piece of insight by Doctor Crane to say
- 46:23let's clear the register and put those two lasers in as the as
- 46:27the actual makeshift laser range finders.
- 46:30So that's kind of how it unfolded and we needed more
- 46:34time. So we delayed and took the risk
- 46:37and said let's delay an orbit and switch to a later landing
- 46:42time because the landing time was originally around 3/3/23 or
- 46:473/24 and we delayed till, you know 5/24 as you know, based on
- 46:51a 2 hour orbit around the moon. So, Tim, anything else?
- 46:55Yeah, it it it's it sounds easy in retrospect.
- 47:00We had the the navigation Doppler Lidar already plumbed in
- 47:04the navigation system and had the range rate data.
- 47:07So the three beams on the the NDL produce a velocity
- 47:11measurement as pursuant and talked about they also produce a
- 47:14range measurement and we were not using the range measurement,
- 47:17we were we had just the range rate as a backup to our optical
- 47:20systems. But because it was already
- 47:22plumbed in there we had to rewrite those rewrite time tags
- 47:26into our measurement loader. But the challenge was the the
- 47:31lasers. So we have, we have these two
- 47:33navigation pods on the vehicle. If you can zoom in there, maybe,
- 47:38maybe not. Anyways, there are these two
- 47:40navigation pods that have the cameras.
- 47:42There you go, 2 navigation pods on either side of the vehicle
- 47:45that have cameras and the laser range finders point in the same
- 47:47direction as the cameras and those angles were optimized for
- 47:52our flight trajectory to give us the best measurements to land
- 47:55softly. The NDL was under one of these
- 48:00and its angles were optimized to test the extent of its
- 48:04performance, not necessarily to feed our navigation system, but
- 48:07to test the sensor because it was a technology development.
- 48:10So after we figured out we could write the measurements into the
- 48:14laser range Finder, we had to quickly tell the computer that
- 48:18the laser beams were pointed in different directions.
- 48:20And so there were a number of attitude transformations of it's
- 48:24not in the same location, it's not in the same orientation, and
- 48:27if you've ever seen engineers doing right hand rule
- 48:29transformations, there were a lot of broken wrists.
- 48:31Put it down here as people were trying to figure out which way
- 48:34is it pointing, and I will tell you that in normal software
- 48:37development for a spacecraft, this is the kind of thing that
- 48:40would have taken a month of writing down the math, cross
- 48:44checking it with your colleagues, doing some simple
- 48:47calculations to prove that you think you're right, putting it
- 48:49into a simulation, running that simulation 10,000 times,
- 48:53evaluating the performance. Usually you find an error
- 48:56because you did something of that rotation wrong and you roll
- 48:59it back and you go again. Our team basically did that in
- 49:01an hour and a half and it worked, so it was one of the
- 49:10finest pieces of engineering I've ever had a chance to be
- 49:13affiliated with. I'd like to add to that that the
- 49:16performance of the navigation Doppler Leader technology and
- 49:21parallel that was developed by NASA's Langley Research Center
- 49:25was outstanding and it was reliable and that's what got got
- 49:29Intuitive Machine some of the key data they needed in order to
- 49:32soft land. Great.
- 49:35Thank you so much for that. Eric Berger with Ars Technica.
- 49:39Eric. Hi, thanks very much.
- 49:43Congratulations. Question for two questions for
- 49:46Tim or Steve. First of all about propellant
- 49:49management, I'm curious how the cryogenic boil off matched up
- 49:52with your expectations and kind of how much prop you had left at
- 49:55the end. And then what is the transfer
- 49:58data transfer rate you're getting now versus what you
- 50:00expected? You know, trying to get some
- 50:02sense of how much data you're going to get back over the next
- 50:05week or so versus your original expectations?
- 50:08Thanks. Propellant.
- 50:11So actually the the cryogens did very well and and just a
- 50:15correction Eric our system doesn't really have boil off.
- 50:19Our tanks are rated to hold the pressure of of the methane.
- 50:22It's very close to space storable really what we're
- 50:25worried about isn't a propellant boil off it is temperature
- 50:30management. We want to keep that cryogenic
- 50:32fluid very cold because the density of that fluid in our
- 50:35engine is what gives us the power of of that thrust system.
- 50:38So really what we were looking at throughout the flight was did
- 50:43our insulation plan and our isolation of the the cryogenic
- 50:46tanks from the hot material, the spacecraft, did that give us the
- 50:49right thermal protection so that we did not heat, heat that cold
- 50:54system up and that worked very well.
- 50:56We found ourselves in a very good situation with propellant
- 50:59all the way through the mission. We did have we used a little bit
- 51:02more helium than we thought throughout the mission and had
- 51:05to adjust our our control approach for that and that was
- 51:10probably the area of concern we run a little bit low on on
- 51:13helium. So a lot of lessons learned
- 51:15there on how we'll manage that going forward that will play out
- 51:18very well. And in terms of the the
- 51:21bandwidth, that's difficult to answer.
- 51:23One of the things that's happening right now, we built
- 51:25fault detection technology into our COM system that if we're not
- 51:29getting a command heartbeat up on two of the antenna pair, it
- 51:32will go through a sequence of powering the radios off,
- 51:35restarting them. And then if they still don't get
- 51:37the heartbeat command signal from the from the earth, then it
- 51:40switches to the other antenna pair.
- 51:42And so one of the first things we're trying to do is get out of
- 51:44that flight configuration and stay locked in on 2 antennas.
- 51:48But with that flip flopping back and forth, right now we're we're
- 51:53trying to get the command up to move out of that flight mode.
- 51:56But there's a beat frequency of we go from a good configuration,
- 52:01the one that's down and then we're about to come up to the
- 52:03new one and we move to a new antenna.
- 52:05And so we're working through that.
- 52:07When we left to come over for the briefing, I think they just
- 52:10about had that solved. But I can't give you a strong
- 52:12number because there's a variability there as we go from
- 52:15different antennas to different dishes around the world.
- 52:21Great. Thanks again.
- 52:22Jeff Faust with Space News. Jeff.
- 52:26Good afternoon. Maybe just to quickly follow up
- 52:28on Eric's question for Tim. What is your best guess that how
- 52:32good the data rate you can eventually get once you optimize
- 52:35the system for the Lander and its configuration?
- 52:38And then also I think this question was asked.
- 52:40Earlier I may have missed the answer.
- 52:41What's your best guess in terms of margin of error of how close
- 52:44you are to the predicted landing site, How many kilometers away
- 52:48you think you touched down? Thanks.
- 52:50Yeah, great questions. Thanks Jeff.
- 52:53Best guess you know in terms of bit rate that's hard to say
- 52:56because that does vary with the antenna size and the sensitivity
- 53:01beach antenna, but we expect to get most of the mission data
- 53:04down once we stabilize our configuration.
- 53:07In terms of landing accuracy, you know with without precision
- 53:11navigation sensors on board the best you can expect to land on
- 53:16an IMU only landing system would probably be in the four to five
- 53:20kilometer range. However, our optical navigation
- 53:24sensors perform Florida State. In fact our optical measurements
- 53:29looked better on the scopes than they had in simulations.
- 53:32So I'm confident that we're well within probably a 2 to 3
- 53:36kilometer accuracy of the landing site for this mission
- 53:41would have been better if we'd had our full complement of
- 53:44sensors as expected. And just as a closing point,
- 53:47Jeff, on this question is that we're planning working with the
- 53:51Lunar Reconnaissance Orbiter and the Arizona State University
- 53:54faculty to do a pass to see if LRO can locate our position
- 54:01precisely and give us a latitude and longitude and we expect that
- 54:05measurement that pass to occur this weekend.
- 54:12Thank you so much for that. Joey Roulette with Reuters.
- 54:16Joey. Hey, thanks for doing this.
- 54:19Question for Tim or Steve, since the Lander is on its side, I was
- 54:23wondering if you could go into how that will limit what the
- 54:27Lander can do with you know, which operational capabilities
- 54:30are impacted by that and which you know, science objectives, if
- 54:34any won't be able to be conducted because it's on its
- 54:37side? Thanks.
- 54:40Well, I'll comment initially. Like I mentioned, we don't have
- 54:45active payloads on the panel EI believe is what's facing the
- 54:50surface of the moon and so therefore the the active
- 54:55payloads that need communications and need to give
- 54:58up, we need to command and we get the telemetry out are all
- 55:01exposed to the outside, which is very fortunate for us.
- 55:06We do have an antenna, however, that are pointed at the surface
- 55:11and those antennas are unusable for transmission to to Earth,
- 55:17back to Earth. And so that really is a limiter,
- 55:20our ability to communicate and get the right right data down so
- 55:25that you know, we get everything we need for the mission.
- 55:28I think it's the most compromised from being on our
- 55:30side. And anything I missed him?
- 55:33No, that was it. Well, maybe one I just thought
- 55:35of his. I I was telling you before about
- 55:37the solar panel on the top deck we had had to angle that at
- 55:42about 30° tilt up for for landing on the South Pole.
- 55:48That was one of the engineering changes we made when NASA asked
- 55:52us to move to the towards the South Pole region.
- 55:54Now we've tipped over and we don't know the health of that
- 55:57solar panel. It would be great to get a
- 55:59picture and or wait until the sun comes around and see if we
- 56:03get any battery charging off that solar panel.
- 56:06So we'll see we're in a great state of charge with the
- 56:09batteries. We're getting plenty of sun on
- 56:11the on the horizontal and now horizontal solar panel and we'll
- 56:15just have to wait and see with that that other panel.
- 56:19Thank you so much, Jonathan Surry, Fox News.
- 56:24Thank you for taking my question and congratulations everyone.
- 56:28My question is also for Tim or Steve.
- 56:31Your team had to essentially rewrite the instruction manual
- 56:34several times while in flight, not just for troubleshooting but
- 56:38also adapting to 1st in space performance of that new engine.
- 56:43Could you give us an idea of how many people were involved with
- 56:45the process, and did the discussions take place in a
- 56:50single war room, or were you conferencing in experts from
- 56:54multiple locations? Just give us an idea of the
- 56:57human logistics involved. So I'll give you a rough
- 57:00overview and then Tim can comment kind of how how it went
- 57:05over the seven day period. We the operations team was
- 57:08structured in into three shifts, red, white and blue shift.
- 57:13Those shifts were supposed to work 8 hour shifts and then do a
- 57:17a handover between shifts. But between those teams, those
- 57:23teams are about 10 individuals and the other team that we
- 57:28activated was called team four. And the team four was a handful
- 57:33of us senior leaders that and engineers that could analyze and
- 57:38take the workload off of the operations teams.
- 57:42So if the operations teams are are wrestling with a
- 57:45particularly thorny problem, they would call team four and
- 57:48say get in here and let's work on this, work on this for us and
- 57:53give us a a solution. So we would pull in the subject
- 57:57matter experts for any of the disciplines that we would need
- 58:01to solve any particular problem and we would work in a war room
- 58:05sense outside the control room to tackle that problem.
- 58:09We would have for example to activate and bring up the
- 58:12simulation or activate and bring up the flat set.
- 58:16We would run analysis cases. We would call the vendors like
- 58:19we called the MDA about the laser laser rage finders.
- 58:24We called NASA and talked about the Deep Space Network with that
- 58:28orbit determination need also all of that chatter in the back
- 58:32that was handled by I would say about 30 people that that would
- 58:38work a given problem on and off based on the on the discipline.
- 58:42But what had happened during the mission was that red, white and
- 58:45blue team and the teams and team four ended up working nearly
- 58:51around the clock. We really could have staffed
- 58:54more, but it takes a lot of expertise to staff those teams.
- 58:58And we ended up kind of melding into, we're all working on this
- 59:02last problem through power, descent and we collapsed into a
- 59:05single red, white and blue team, all of it.
- 59:08And to get that solved, which we're going to go back and look
- 59:11at and see, you know, we really, really work the team hard.
- 59:16They're put a lot of hours in. I think one of the longest days
- 59:19was 48 hours long and another another day was 40 hours long
- 59:23for some of the folks. And that's, you know, just just
- 59:26working too hard. And we need to give them rest so
- 59:29they can be bright and make the right engineering decisions.
- 59:33So we got some lessons learned in that area, but we did it and
- 59:37it was worth it. And it was a whole idea of
- 59:39persevering through the challenges and never giving up,
- 59:42Never ever give up until the last ditch solution you could
- 59:47find and then keep thinking about it if it didn't work.
- 59:50So just a testament to a great operations team.
- 59:53Yeah, I'll add to that. You know, our operations concept
- 59:59was a, a a blend of. Human spaceflight for space
- 1:00:04station and space shuttle, we have, you know that's in our
- 1:00:06culture here in the Houston area.
- 1:00:08Some of us had worked on the all hadamorphous project at NASA,
- 1:00:11which was in some way has the DNA that that led into Nova C We
- 1:00:16had people with a military operations background and then
- 1:00:18we had people from commercial network operations.
- 1:00:21And so we put all of that together and we came up with our
- 1:00:24own unique blend of how we were going to do spacecraft
- 1:00:26operations. And a big focus of that was the
- 1:00:29people inside the room on the red, white and blue teams, Keep
- 1:00:32the vehicle alive, keep the vehicle alive and doing what
- 1:00:35it's supposed to do. And then all the mission
- 1:00:38directors, myself, Jack 2, Fish Fisher and Trent Martin, we had
- 1:00:41the responsibility to interface with Team Four.
- 1:00:44And we would be able to say, I have this problem, I can't solve
- 1:00:47it with the resources I have in the room and and do what we're
- 1:00:50supposed to do. And so we would shed those out
- 1:00:53to Team Four and they did an amazing job.
- 1:00:56Whether it was talking to the vendors or developing a
- 1:00:59procedure, they took that off the plate and that load balance.
- 1:01:03Even though he's right, you know, I joked this morning that,
- 1:01:06you know, how was your day? I said, well, this mission was
- 1:01:08the longest seven day day of my life.
- 1:01:11But it it really, it really allowed us to focus on keeping
- 1:01:15the vehicle alive and keeping it moving on its way to the moon
- 1:01:19and doing the things we needed to do while problems and
- 1:01:21anomalies could be solved in the backroom.
- 1:01:24And you know, this is a story that everybody on that team is
- 1:01:28going to be able to tell for generations about how we landed.
- 1:01:34Irene Klotz, Aviation Week, your line is open.
- 1:01:39Thanks. If I understand that incredible
- 1:01:42sequence of events correctly, was it just serendipity that a
- 1:01:46situation developed with that elliptical orbit that caused you
- 1:01:51to try and get the laser range Finder data where you realized
- 1:01:57it wasn't working before it would have actually been needed?
- 1:02:01And when during the touchdown, would that laser range binder
- 1:02:07nominally have been activated? I think I understood Irene, the
- 1:02:17question. It was actually fortuitous that
- 1:02:22we had an elliptical orbit after lunar orbit insertion, because
- 1:02:29we would not have arbitrarily activated the laser range
- 1:02:33finders prior to power descent. We tested them on the ground, we
- 1:02:38flew them on aircraft, we flew them on helicopters, we and and
- 1:02:44we assumed after all that testing they worked.
- 1:02:48So the first usage of those laser range finders was during
- 1:02:52was supposed to be during the power descent.
- 1:02:54But because we had such a low parallel, we activated a laser
- 1:03:00and found the problem. So that was fortunate and that
- 1:03:02was a bit of luck for us that then we identified that they
- 1:03:06weren't firing. So at that point then that was
- 1:03:10recovered. Like I said, at the next morning
- 1:03:13we uncovered that and then we had to work feverishly to figure
- 1:03:18out an alternative solution. Anything there Tim?
- 1:03:22Yeah. Just the second part, Irene, to
- 1:03:23your question of when would they normally have come on.
- 1:03:25Normally we would have turned them on after deorbit insertion
- 1:03:29about an hour before landing. And we expected the, what we
- 1:03:32call the terrain relative navigation LIDAR, their laser
- 1:03:37range Finder that would have operated really from about 50
- 1:03:41kilometers altitude all the way down to landing.
- 1:03:44And then after pitch over, we had a laser on the other side
- 1:03:47that would take us from a kilometer down.
- 1:03:49So we would have probably been 5 minutes to landing before we
- 1:03:52would have realized that those lasers weren't working if we had
- 1:03:55not had that fortuitous event. So serendipity is absolutely the
- 1:03:59right word. Jackie Waddles, CNN.
- 1:04:06Hi, everyone. Thanks so much for doing this.
- 1:04:08Had a quick question for Steve or Tim.
- 1:04:12I know everyone's really curious about the photos here.
- 1:04:14So do you guys have any indication of Eagle Cam is in a
- 1:04:17position to pop off the Lander and take some pictures?
- 1:04:21And to that end, if you could just clarify for all of us, are
- 1:04:25there any specific payloads whether commercial or NASA?
- 1:04:28I know some of them are passive and you're still working on
- 1:04:32figure out these data down links and stuff, but are there any
- 1:04:35that you know for sure or just haven't gotten any data yet and
- 1:04:39don't know if you will get data from?
- 1:04:41Thanks so much. Well, fortunately again Eagle
- 1:04:47Cam sits on a panel. Let me show Tim if panel EI
- 1:04:59believe is towards the surface of the moon.
- 1:05:02Eagle Cam sits over here on this panel and we plan to eject that
- 1:05:07camera off the side, so it will fall about 30 meters or so, then
- 1:05:14maybe not that far away from the Lander and get a good shot of
- 1:05:17the Lander position this way. So we're looking to power up
- 1:05:22that Eagle Cam. We were waiting on getting
- 1:05:24commanding ability power that up, clear that SD card and fire
- 1:05:29the camera and so we can get a A view a back to our Lander.
- 1:05:33So that's a very exciting image for us.
- 1:05:36The reason it wasn't fired as we were landing was because of this
- 1:05:41NAV system initialization that we had to do which put a flag up
- 1:05:46to flag the Eagle Cam not to fire.
- 1:05:50So that was part of the troubleshooting we had to do to
- 1:05:54to get the Doppler LIDAR into the NAV system.
- 1:05:59We had to do these navigation initializations and that shut
- 1:06:02off the Eagle Cam and we knew that was in the software, but we
- 1:06:05just did not have time to go fix that.
- 1:06:07And so now we'll get it and get the image in the orientation
- 1:06:11that we need. The other question you had about
- 1:06:14commercial payloads, we think we can meet all of the needs and
- 1:06:20from the commercial payloads that we have in the orientation,
- 1:06:23we have the one on Panel E that's covered right now or
- 1:06:28shaded by the Lander and the surface is the Arc Cube project.
- 1:06:35And we believe we've got an image of that already that we
- 1:06:38can download and share with our our customer.
- 1:06:43I'll add that for the NASA science payloads, as we said
- 1:06:46earlier, the many of them have already taken a lot of data, a
- 1:06:49lot of measurements in transit and also on descent.
- 1:06:52We're still checking to see if in the current suspected
- 1:06:56orientation of the vehicle whether there will be any
- 1:06:59particular measurements that can't be made in some of the
- 1:07:02payloads. So, for example, we want to make
- 1:07:04sure that the laser retro reflectors, which are normally,
- 1:07:08you know, pointed up so that when the Lunar Reconnaissance
- 1:07:11Orbiter flies over it can pulse them with a laser beam and find
- 1:07:14their position. We'll have to check to make sure
- 1:07:16that they can still be illuminated.
- 1:07:18They probably can be when the orbiter's fault is flying it up
- 1:07:21at a further angle away on the trajectory, very similar to what
- 1:07:25we found with the recent slim landing from the Japanese Space
- 1:07:29Exploration Agency. But we are doing an assessment
- 1:07:32to see are there any measurements still to come that
- 1:07:34from any of the NASA supply payloads that most likely can't
- 1:07:38take place particularly because of this new orientation?
- 1:07:43Great. Thank you so much for that.
- 1:07:45Will Robinson Smith for Space Flight Space Flight now.
- 1:07:48Will, Yes. Hi, thanks for taking the time
- 1:07:52to answer our questions here. One for Joel and for Sun.
- 1:07:57If I could, given the success and now the operability of the
- 1:08:04NDL, will that become AI guess highly recommended or required
- 1:08:10payload on future eclipse missions?
- 1:08:13And what are the potential implications or or knock on
- 1:08:17effect for the human landing system Landers?
- 1:08:20Will NASA recommend that Blue Origin and SpaceX implement that
- 1:08:24into their landing systems? Thanks.
- 1:08:27I'll take a, I'll take a shot for Sun, but please please add.
- 1:08:31So for a commercial lunar payload services initiative, we
- 1:08:34don't prescribe to the company partners that are doing this as
- 1:08:38a service, you know what techniques or technologies they
- 1:08:40use. But as you can imagine all these
- 1:08:43different companies are always looking for low risk, good
- 1:08:47performance ways to gather the data or conduct the operations
- 1:08:50that they are going to conduct for NASA.
- 1:08:53So we I'm sure that the story as you can tell now is very public
- 1:08:57about about things like the performance of the NDL.
- 1:09:01And we would think that people that are looking at lunar
- 1:09:04Landers would be checking into that technology.
- 1:09:06Now that it's actually been flight proven operationally on
- 1:09:09probably the an unanticipated flight test mission, right,
- 1:09:14actually use it operationally. I would say the same thing.
- 1:09:17You know, the human Lander system partners have their own
- 1:09:20techniques and their own approaches that they're taking.
- 1:09:23But again, now that this has been actually shown to
- 1:09:25operationally work, I would think it's going to be of great
- 1:09:28interest to folks that want to travel to the moon first time.
- 1:09:31Yeah, I will add, you know, we've actually did.
- 1:09:34NASA has already licensed this technology to a small company to
- 1:09:37commercially provide this to whoever wants to buy it, right.
- 1:09:41And so this only adds more validation of the system.
- 1:09:46There's just a technical reason to add it right beyond the
- 1:09:49aspects that Joel talked about because it is an order of
- 1:09:52magnitude more accurate in precision and measurement of
- 1:09:57range and velocity components. It's half the power, half the
- 1:10:01mass of the traditional approaches that we've used in
- 1:10:04the past and the volume in terms of signs is about 1/3 of it.
- 1:10:08So if you just look at it from a technical perspective, it just
- 1:10:12provides all these benefits. And so I'm sure future vendors
- 1:10:17will look at this type of capability anew and and try to
- 1:10:23incorporate these types of technologies.
- 1:10:24And that's why we're doing these missions right, is to develop
- 1:10:29better and better capable systems that allow us to do this
- 1:10:32more reliably, more capably and hopefully more sustainably and
- 1:10:36more cost efficient wise. So in fact, after the landing, I
- 1:10:40did joke with Steve there, it's like, hey, now Are you ready for
- 1:10:44I Am 2 because we have 3 payloads already ready to go on
- 1:10:47I am two, right. And so we're ready to
- 1:10:50demonstrate even more stuff that will help the greater space
- 1:10:54economy that burgeoning in here in the US and and we just want
- 1:10:59to augment that as much as possible we can with what we're
- 1:11:01doing. Yeah, I'll chime in as well.
- 1:11:04You know, as you look forward to future emissions and as we begin
- 1:11:08delivering cargo emissions with a metric ton and more, you know
- 1:11:11those those payloads get more and more valuable.
- 1:11:14And as those payloads get more and more valuable, we're going
- 1:11:16to have to prove to our customers that we have
- 1:11:17robustness in our landing systems.
- 1:11:19One of the ways you achieve robustness is with redundancy or
- 1:11:22with the similar redundancy. So having two ways of measuring
- 1:11:25that landing. We had a camera system on board,
- 1:11:27but if you have a camera system and a laser system, one might
- 1:11:31fail in a way that the other one might not.
- 1:11:33And so I can see that as the lunar economy opens up, as NASA
- 1:11:37begins to send cargo and larger, more expensive payloads with
- 1:11:40companies like ours and others, that you're going to see demand
- 1:11:44for these kind of sensors complementing a suite of sensors
- 1:11:48that you use to guarantee safe landing is going to be something
- 1:11:50that that will be an industry standard.
- 1:11:54Thank you for that. We are going to try and take two
- 1:11:56more questions. So I'm going to ask you guys to
- 1:11:59be brief in your remarks so we can get the get through these
- 1:12:01questions. First up, we have Marsha Smith
- 1:12:04with spacepolicyonline.com. Marsha.
- 1:12:08Thanks so much. Getting back to the
- 1:12:11communications question, I gather that part of the
- 1:12:14challenge is that you have so many different sites around the
- 1:12:16world with different capabilities.
- 1:12:19But I know that you would talk before you launched about the
- 1:12:22challenges of communicating at the South Pole.
- 1:12:25But how much of the calm problems are related to the
- 1:12:27ground stations and how much to the place where you are on the
- 1:12:31moon? And what lessons are you going
- 1:12:33to learn from all of this for the Artemis missions?
- 1:12:39Well, yeah, I'll answer some of that question.
- 1:12:44What you get is a phenomenon at the South Pole that NASA is
- 1:12:47interested in understanding since that's where our future
- 1:12:51Artemis missions are targeted or NASA's future Artemis missions
- 1:12:56are targeted is a is a frequency multi path condition and so are
- 1:13:04you going to get multi path interference on your
- 1:13:07communication frequencies? Fortunately we think the
- 1:13:10antennas that are pointed towards the moon will give us a
- 1:13:13really good understanding of that phenomenon at the South
- 1:13:17Pole. Another serendipitous moment,
- 1:13:20right? But I would say that we thought
- 1:13:24about this landing on the South Pole quite a bit and if you look
- 1:13:27at the mock of all the antennas are up high and pointed like we
- 1:13:31like towards Earth. When you're sitting on on the
- 1:13:35surface of the Moon in transit, it's very difficult.
- 1:13:38You have to constantly change your attitude to point the
- 1:13:41antennas back to Earth when you're headed to the Moon.
- 1:13:44So we're going to figure out an antenna location map for
- 1:13:49subsequent missions and even mission two that gives us an
- 1:13:53antenna pointed back at the Earth when we're flying out
- 1:13:55towards the towards the Moon for sure.
- 1:13:58Also in this first ever use of our lunar data network, of this
- 1:14:04commercially now available data network made-up of these large
- 1:14:09radio astronomy dishes that we've stitched together in a
- 1:14:13network. Some of those dishes have had
- 1:14:18have had configuration issues. Some of those dishes have had a
- 1:14:21weaker power band. So we can all operate on this
- 1:14:26frequency S band set of frequencies.
- 1:14:30However, the power to reach the moon is what came into account
- 1:14:34as we went around and out towards the moon.
- 1:14:38The further we got, the some of the times those power
- 1:14:42transmission levels were too low to have us keep the carrier
- 1:14:46locked, locked up on the radios. So that was some of the
- 1:14:51challenges and that's what we're looking for going forward is to
- 1:14:54really regularize that lunar data network so that
- 1:14:59operationally we know the configuration we can go upgrade
- 1:15:03to put additional orbit determination capabilities
- 1:15:07within our baseband units at each antenna site.
- 1:15:10And and the best thing will be when we get our data relay
- 1:15:13satellites in orbit, we'll have that problem licked and we can
- 1:15:19communicate short distance from the surface up to a satellite
- 1:15:22and relay that back to Earth in a in a in a more traditional
- 1:15:26way. So looking forward to those
- 1:15:27advances in the communication system.
- 1:15:31Thank you. And we have one last question we
- 1:15:33can take this afternoon with Adam Mann from Science.
- 1:15:36Adam. Hi there, I'm with Science News
- 1:15:42actually and I guess this is for the Intuitive machines folks.
- 1:15:46I'm wondering maybe you've answered this already, but I'm
- 1:15:48just wondering if you have any idea how long OD might be able
- 1:15:53to stay operational on lunar surface.
- 1:15:57Well, it's a great question and and you're going to bring a tear
- 1:15:59to my eye. We know at at this landing site
- 1:16:03the sun will move beyond our solar arrays in any
- 1:16:07configuration in approximately 9 days.
- 1:16:10And so the early missions are all solar powered and require
- 1:16:15that. And then once the sun sets on on
- 1:16:18OD, the batteries will attempt to keep the vehicle warm and
- 1:16:23alive, but eventually it'll fall into a deep cold.
- 1:16:26And then the electronics that we produce just won't survive the
- 1:16:31deep cold of lunar night. And so, best case scenario,
- 1:16:35we're we're looking at another nine to 10 days.
- 1:16:37And then we will, of course, the next time the sun illuminates
- 1:16:42the solar arrays, we'll turn our dishes to the moon, just to see
- 1:16:45if the radios and the batteries in the flight computer survive
- 1:16:48that deep cold. The solar array should, they
- 1:16:51should survive the deep cold and provide power, but we'll just
- 1:16:54see if our electronics made it through.
- 1:16:55We'll take a look, we'll take a listen.
- 1:16:57By that time we'll have gotten very, very good at at listening
- 1:17:00to that signal, but we do expect probably a maximum of another
- 1:17:04nine to 10 days. Thank you so much, Tim, and
- 1:17:08thank you to everyone who submitted questions this
- 1:17:11afternoon. And thank you to our briefers
- 1:17:14for taking the time to discuss this historic mission enabled by
- 1:17:17the agency's Commercial Lunar Payload Services or Eclipse
- 1:17:21Initiative. We hope you'll continue to
- 1:17:24follow along on this mission by keeping track on Intuitive
- 1:17:27Machines's website and on nasa.gov/CLPS that will wrap
- 1:17:34today's briefing. Thank you so much.
