Hi everybody and welcome back to the show.
0:02
Today we're going to be presenting to you, a Twitter
0:05
spaces, talk with Elon Musk where he discusses the latest
0:10
updates for the Starship, super heavy program after the launch
0:14
attempt than happened on for 20 of this year.
0:17
And there are some very good Insight from Elan himself in
0:21
this episode. So, please sit back and relax
0:23
and listen to this Twitter spaces.
0:25
Recording, it seemed odd everyday.
0:27
Astronaut is messed up. My co-host and determine if
0:31
those people actually want to add to speak and provide some
0:34
important questions, definitely feel free to just.
0:37
Yeah sounds great. Thank you Lon.
0:39
Hey Irene Hey Lon. It's been like that it has that
0:46
was very exciting to be in Boca Chica.
0:49
You always live up to your promises about exciting times
0:53
and SpaceX Yes. Punctuality is not my strong
0:57
suit, but I do deliver in the end.
0:59
Yes, you do excitement was guaranteed and it was delivered,
1:05
exactly. Yeah, we just get right into it
1:08
at. So I think probably people have
1:11
enough time to get on or hopefully hopefully yeah, as it
1:16
basically the outcome was roughly in the sort of what I
1:21
expected and maybe slightly exceeded my expectations.
1:25
Roughly what I expected which was or all hoped for I should
1:28
say which is that we would get clear of the pad with minimal
1:32
damage the pad and I'm glad to report that the pat damage is
1:36
actually quite small. And looks like if you were quiet
1:39
repaired quickly and that we would also get significant
1:43
in-flight data. Particularly, with respect to
1:46
the pressurizing of the tanks, with the propellant liquid,
1:51
which is called, which hajin has pressurization as opposed to
1:55
say, A falcon 9 which uses a helium.
1:57
Pressurization. But helium isn't very short
2:00
supply and extremely expensive. It's way better to, or, to
2:04
essentially pressurized with the liquid form of the oxidizer and
2:07
fuel. So that that actually quite
2:09
good. And we also went supersonic
2:12
which is that was no problem at all.
2:14
And he, so I'm going through obviously some good news items
2:17
here. The vehicle.
2:19
Structural margins appear to be better than we expected.
2:23
As you can tell by the fact that the vehicle is actually I'm
2:25
doing somersaults towards the end and still staying intact.
2:30
So that's also good. And yeah, so I will actually
2:34
feel like that was a great flight at SpaceX team did.
2:37
Excellent work. We made a lot of progress and I
2:40
think for a technique from a broadcast standpoint and Pad
2:45
standpoint, we are probably ready to launch in six to eight
2:51
weeks. The longest, the item that is
2:54
probably requalification of the flight termination system.
2:59
Because we did initiate the fight termination system, but it
3:02
was not enough to it took way too long to rupture the tanks.
3:07
So we need a basically a much we need more detonation cord to
3:13
unzip the tanks at altitude and ensure that they basically the
3:18
rocket explodes immediately. If there's an a if I
3:22
termination, is this necessary. So requalification of the is I'm
3:26
just guessing here that recalled cake of the Much longer
3:29
detonation cord to tons of the rocket in a bad situation is
3:35
probably the long lead item. What was the time lag?
3:42
It was pretty long, I think it was on the order of 40 seconds
3:45
ish. So quite long.
3:48
The yeah. So Now, it's the rocket was in a
3:54
relatively low air density situation.
3:57
So the aerodynamic forces that I was experiencing were, will be
3:59
less than if it was at a lower lower down in the atmosphere.
4:03
And so that are now forces would have included, I think low point
4:07
the atmosphere aided in the destruction of the vehicle.
4:10
And in fact that that's what happened.
4:11
When the vehicle got to load off altitude, the atmospheric
4:15
density was enough to cause structural failure, but this is
4:19
obviously something that we want to make suture.
4:21
Aerosol it before proceeding with next flight.
4:24
Let's see, I'll go through a bunch of notables so we we
4:28
actually at liftoff there were three engines that we didn't, we
4:32
chose not to start essentially, the oh, that hit aborts that.
4:36
And so we actually looked at off with 30 engines, which is the
4:39
minimum number of engines those interested or explode.
4:42
But they were just the system. Didn't think they were healthy
4:44
enough to bring them to a full thrust so they were shut down.
4:49
Then at t, plus 27 seconds and 219 lost Communications
4:54
Concurrent with some kind of energetic event that liberated.
4:58
The outer heat shield from the e engines 17, 18, 19 and 20 area.
5:05
You can see this on video actually and by the way, if
5:08
people have like, basically think that maybe something
5:10
different from this occurred that would be interesting too.
5:12
Because I know people, some people have looked very closely
5:14
frame-by-frame at video but this is the SpaceX best assessment
5:18
after a week anyway. So something bad happened at t
5:22
plus 27 seconds because engine 19 law school Communications and
5:26
some kind of explosion happened to knock out the heat shields of
5:30
engines. So much pain, 18, 19 or 20 and
5:33
yeah. And the possible fire scene from
5:35
The Afghan starting after this event and continuing through
5:38
flight. The rocket kept going, though,
5:40
for at T plus 62 seconds, we see additional after heat shield
5:45
damage and your engine 30, however, the engine continues to
5:49
run and then at TA 5 seconds is worth Things really hit the fan.
5:56
We see engine 6 will last the communication to thrust vector
5:59
control and roughly. At, from this point onwards, we
6:02
lose thrust vector control of the rocket.
6:04
So we lose steering at t. Plus 85 seconds, was that engine
6:08
6 that kept trying to relight to Possibly I was like I don't know
6:15
was there one that one looks like and footage like it just
6:18
kept attempting to relight relay relay over and over which is
6:21
pretty wild to see. I don't think I've ever seen
6:23
that before and it was one of the center ish engines.
6:29
That's her saying. Okay, we do have relight logic
6:32
in the center engines but not in the outer engines, I believe.
6:36
So the third basically at Landing engines have relied
6:39
Logic. The perimeter engines don't set
6:42
that isn't, that's entirely possible.
6:43
Although if the engine is detecting significant issues
6:47
that should not be going into a tree light cycle yeah what's
6:51
your best guess as to what caused the initial engine issues
6:56
and then I guess it, cascaded a After that.
6:59
But what do you think happened? It's I think we don't know with
7:05
certainty. Obviously, the rocket stayed on
7:07
the launch pad for a while and we did generate quite the rock,
7:11
tornado at the base of the vehicle and at our first guest
7:14
would have been that The Rock tornado would have caused the
7:17
significantly significant damage to the engines but at least we
7:22
don't we do actually do not see obvious.
7:24
We actually do, weirdly do not see evidence of the rock
7:28
tornado. Actually damaging engines or
7:31
heat shields in a material way. It may happen.
7:33
We have not yet seen evidence that for the next flight we
7:36
certainly will be taking off faster.
7:38
So this for this flight, weird on the side of babying, the
7:42
engines and just gently starting each engine, one at a time.
7:46
And they're quite the engines on Brewster seven were built over a
7:50
long period of time. So, each Anton was a little bit
7:52
of a unique item and whereas the engines on Brewster line which
7:58
is next are much newer and more consistent.
8:01
And really with With significant reliability improvements over
8:04
booster 7. So I think we'll see you a much
8:08
more robust to engine situation with rooster 9.
8:11
The heat shield won't Orchard should say the shields which are
8:14
both force and heat shields around the engines for booster 9
8:20
are much better because they were retrofitted for Brewster
8:24
seven year, we record heat shields whereas mr.
8:27
Is designed in so the Riveter much stouter.
8:31
Will you be doing something with the Raptor?
8:33
Chill system on the on booster 9 differently than what you did
8:36
with seven? It seems like that was like an
8:40
Expendable part of the pad, essentially, with having all of
8:43
those hoses, rip free. I'm guessing that's something
8:45
you would like to avoid having to replace every time in the
8:48
future. Yeah, over time, we're
8:51
definitely needs to be like a rabbit reflect capability, so
8:55
they can't be any external items over time.
8:57
It was actually just good to get this vehicle off the ground
9:00
because we've made so many improvements in the booster.
9:03
And I know beyond that it really really just need to fly this
9:07
vehicle and then move on to the much improved.
9:10
Rooster nine and later ship designs.
9:13
But so thing we want to ensure of probably most with the next
9:19
Inflight is that we do not have that any kind of central Nexus
9:24
that controls that affects multiple engines is extremely
9:27
robust and with extra shielding so that that we don't have a
9:33
sort of a single point that can take out multiple engines.
9:35
And for sure, we don't want a single point, they can take out
9:38
the thrust vector control which is entrance during the range of
9:43
detail. We guarantee our is like level 9
9:45
rocket was a tree all the way to how rockets work.
9:49
Understood, can I try again? How do I have?
9:51
I can confirm that we have all been doing a massive amount of
9:55
speculation out here. And I guess one of the big
9:59
points that a lot of us have been wondering, is related to
10:02
Stage separation. So, I guess, the two part
10:04
question, like, what actually triggers second stage, ignition?
10:09
And also the second part of that question did ship 24 attempt to
10:14
light its engines after the destruction of booster 7.
10:19
No, it did not when they termination is executed, its
10:24
executor on both, so the ship currently does not attempt to
10:27
save itself. Arguably, maybe two.
10:31
That's good point. Yeah, it's crazy.
10:32
And looks like the engines lit after the booster, like, go, and
10:37
after the booster finally blew up, like there's what looks
10:39
like, A combination of it.
10:56
But but like the, so the very things that are like important
11:01
for the next flight are ensuring that thrust vector control.
11:04
We don't lose the rocket thrust vector control.
11:06
So isolation with respect to control, which with the booster
11:09
nine is a lot easier because we use electric motors to steer the
11:14
engines as opposed to hydraulic actuators where you've got a
11:19
common manifold between the hydraulic actuators.
11:21
So if you lose hydraulic pressure, if I can It's you can
11:24
look, there's multiple engines especially if you have some kind
11:28
of failure in the hydraulic system, the electric actuator to
11:31
engines will be much more isolated and not have the single
11:34
event failure. As long as they did not lose
11:37
power or comes along since you've gone ahead and excavated
11:41
your your launch mount a bit, I assume you're gonna go ahead and
11:44
put in that the steel grid and the word they lose.
11:47
Do you think that will fully address the issue of the wider
11:51
than expected? Debris field?
11:52
And are you expecting any? A pushback from environmental
11:56
and kind of community groups that this, that this event did
12:00
put debris where it wasn't expected.
12:04
Yeah, the we're going to be putting down a lot of Steel.
12:07
The debris is really just basically sand and rock, so,
12:10
it's often they're not toxic at all or anything.
12:12
It's just like a sandstorm. Essentially, basically a
12:15
human-made set Stan storm, but we don't want to do that again.
12:19
We were very putting down a, a very strong steel.
12:24
Sandwich that is basically a water jacketed sandwich, that's
12:27
two layers of thick, very thick plate steel that a better.
12:30
Also perforated on the upper side so that you have, but what
12:33
is basically a massive super-strong steel shower, head
12:38
pointing up and then the water pressure has coming out of
12:42
there, has to exceed the pressure for the engines.
12:45
Thrust is exerting on the steel plate on the vehicle or Stan,
12:49
but, which is is all doable, and Ed being done and so it should
12:52
be much less Dusty. And we should not have a rock
12:55
tornado with the next flight. Hey Ilan, it's Joey from
12:59
Reuters. Why couldn't you install that
13:01
before this launch, was that a technical reason or a regulatory
13:04
reason that it wasn't ready to do stuff like we expected, we'd
13:08
expected to dig a hole. We would not have Teflon.
13:12
So the reason we would not expect to excavate a whole,
13:16
we've done a static fire of the booster and that that had just
13:22
result in You're fairly modest erosion of the high strength
13:27
concrete at the base of just called found a gets a sort of
13:30
special, but basically the strongest highest temperature
13:34
form of concrete that you can get steel-reinforced everything.
13:37
And so if we thought it would be fine for one launch, we would
13:41
erode some amount of the concrete but that it would be
13:44
fine. We certainly didn't expect to
13:46
effectively what it looks like when we were enough to full
13:49
thrust, probably shattered the concrete, so Is it possible that
13:54
the base layer failed first and not the actual van dijk layer on
13:57
top. It is, we are getting into some
14:00
amount of speculation here but it's one of the aspirations.
14:04
And one of the more probable explanations is that when we ran
14:08
up to full thrust that the that we may have, compressed, the
14:12
sand underneath the concrete to such a degree that the concrete
14:16
perfectly bent and then cracked. That's it.
14:19
That is a leading theory. But as we definitely want to do
14:22
not have the gain and and I was never a long time ago, we
14:25
thought it would just be fine for one launched.
14:26
We were owed some on Deck just as we did with the booster,
14:30
static fire. And and then for the next
14:32
launch, we're going to put in the deal.
14:35
Mega steel pancake, this thing's a beast.
14:37
That is why the steel pancake over like a flame trench or
14:41
something like that. You can do it either way but the
14:47
and that's just from schools of thought there.
14:49
The important thing is that you have a regenerative Lee cooled,
14:52
like wherever the flame is hitting that your that that is
14:55
regenerative lie and evaporatively cooled.
14:59
So, what you'll see is that how to make Steam Cloud, but not a
15:02
dust cloud so that we, you know, we're friends, some both ways,
15:07
you could do it both ways. But and I both work, the
15:10
acoustic environment is worse with a flat face.
15:12
So, as you might imagine, but the payload is so far up in the
15:17
payload 400 feet away from where the plane from, where the plume
15:20
is impinging. So, it's so far away that the
15:23
Acoustics are not actually, not that bad and the payload
15:25
fairing, so we're not have to worry too much about it being
15:29
too loud in the payload Fairing and so it can be done either
15:32
way, but this is one way and we were pretty confident, this will
15:36
work and we're going to extend the steel Beyond just underneath
15:40
the rocket. It because you want to make sure
15:43
we don't take up concrete elsewhere.
15:46
And and then it get, we're going to connect the load of the
15:51
massive steel sandwich underneath launch pad into the
15:55
launch found legs. So it can take that load in
16:00
tension, as well as a compression.
16:04
So I don't know if that's a true Pro pretty good about that.
16:06
You'll see it come together next author.
16:08
So but like say that that actually we're it is not
16:12
currently appear to be what prevented the rocket from
16:16
getting closer than it did. There was obviously a caps a
16:21
flame path somewhere within the vehicle structure that As some
16:27
of the engines failed there, maybe it would appear to be a
16:31
foot like a flame path to a piece of avionics or control
16:35
system that knocked out the thrust vector control.
16:40
Once you knock out thrust vector control, the rocket no longer
16:42
has serious during Authority. What things do you think went
16:47
better than you expected, and what things went worse than you
16:50
expected? It was pretty close to what I
17:01
expected at least in this. And those for this fight was
17:03
pretty close to what I expected getting past.
17:05
My excuse was a pretty big deal. I was actually quite shocked.
17:09
I don't know why I had that whole the fins in the flaps up
17:13
front and all that stuff especially starting to lose
17:15
Control Authority, with TVC going out.
17:17
That was pretty impressive. Thing, just kept chugging along
17:20
and punching right through. So that was my big one.
17:23
If it made it through Max Q, I was gonna consider that a pretty
17:25
big milestone for sure. Yeah, definitely, that's for
17:29
sure. An important Milestone and it
17:31
got pretty close to Stage separation.
17:33
If we had maintained thrust vector control and throttled up,
17:37
which we should have, because we needed to compensate greed, lust
17:40
too many engines, so we need to read which of the throne, but
17:44
the remaining engines to make up for the missing ones.
17:47
But if we don't lost, if we're thrown off their many engines
17:49
and maintain thrust vector control, we would have made it
17:51
to staging which would be cool. Yes, that that's our goal for
17:54
the next flight is make it to staging.
17:58
Hopefully 16 and staging and get get older.
18:02
So everybody started going to orbit with the next?
18:04
Why did the my booster command separation?
18:06
Get it actually try letting go of Starship and it just couldn't
18:10
because of something or did not even get that far in the
18:14
program. Now, at first, they did not get
18:17
to the point where it would do separation.
18:20
And I want one could argue that at the point, which the booster
18:23
is kaput. The ship may as well just take
18:26
off and keep going. But the problem is that we have
18:30
a very precise targeted entry point in the Pacific.
18:34
The ship really wouldn't have the Delta plastic the capability
18:38
of reaching that Target points. Are you are?
18:40
So even if you wouldn't want it re-entry over Africa or
18:43
something and then just just touching down randomly.
18:46
Yeah, exactly. Yeah.
18:48
So it's with it would only be worth really starting to show up
18:52
if the ship is able to complete a submission and reaches
18:56
targeted Landing point, just the west of Hawaii.
19:00
Ilan, would you change the flight profile all?
19:03
And what would you have to do to actually reach orbit?
19:06
As opposed to the 146 miles? That this one, seems like that
19:10
would have been the max altitude?
19:14
Yeah, yeah. So it's mostly about velocity
19:16
that rather than elf to, but I'd said, I think we've got a better
19:19
than 30% chance of reaching Orbit on the next line.
19:23
So, I'd say that my expectation for the next flight would be
19:29
more likely to reach over tonight.
19:32
And are you actually in with are you going to be attempting orbit
19:34
or like doing the same profile of re-entering over Hawaii?
19:37
And that whole thing? Yeah, we're just going to do
19:40
repeat. Basically the goal of these
19:41
early missions is just information going to have any
19:44
payload or anything. It's let's try to learn as much
19:46
as possible and that's a and that's why we consider this to
19:50
be a success because since the goal of the flight was to learn
19:54
a lot and we learned a lot, I would characterize it as a
19:56
success, obviously not complete success but still no less
19:59
successful. And I always want to frame this
20:02
the difficulty of this with respect to the sort of Soviet
20:06
Union Warsaw Pact rocket developments of the past, for
20:10
which I have a lot of respect. But back in Russia and Ukraine
20:13
are working together. They made great.
20:15
I did great stuff in space after I say yeah maybe wonder they can
20:20
respond to that but much more productive.
20:23
Like the N1 program is always worth always recommend people
20:26
read the history of the Soviet and one program which was the
20:30
competitor. Rocket to the Saturn 5, Euro
20:33
certified Moon rocket. And that's, that's a point
20:37
you're talking about late 60s early 70s where the Soviets were
20:40
really at their a game. They were just really fantastic.
20:44
They said they had a plus players that it's fair to say
20:48
that their motivation was maximized.
20:50
Success means, you are hero of the Soviet Union.
20:52
Failure of you're probably going to the gulag so a plus players
20:58
maximum motivation and so The N1 failed at every solve it so that
21:05
those are that's the team for one.
21:07
We really have to have a tremendous respect for the end
21:09
one team and they did not succeed so and it didn't help
21:12
that glushko never wanted that thing.
21:13
Any way you wanted it, he wanted his own Mega rocket.
21:17
Then, what score, Leo, Carrillo have died.
21:19
It was game over for that poor thing.
21:24
So the storage unit, certainly suffered a massive lost with
21:27
Karlov dying. He was there for brown
21:29
basically. So That for a car, that was
21:32
awesome. It's like losing your best
21:33
player at the worst time, really?
21:35
But nonetheless, it's there was so many super smart people in
21:38
that program and they're really know what they're doing with
21:41
rockets and maximum motivation. I do not succeed.
21:43
So it just always bearing that in the N1 is the closest to
21:47
Starship of any rocket that's flown.
21:50
And I thought shop is actually a bit more risky in some ways and
21:53
that we've got a cryogenic fuel and think about a cryogenic
21:56
fuel. Is it can gasify and form fuel
22:00
oxygen pockets. And that kind of thing, it's
22:01
always harder to deal with the gas with a cryogenic fuel.
22:04
Then with a fuel that is liquid at room temperature kerosene,
22:07
basically. Rocket grade jet fuel is, which
22:12
is what Falcon and the anyone used.
22:15
So they've got real risk in that respect.
22:17
We're running at a higher chamber pressure engine that's
22:19
full flow stage combustion so it's the most complex and
22:22
difficult engine configuration. But the one with the highest
22:25
efficiency and we're using autogenous pressurization, which
22:29
I don't think they did and I feel so those are things and
22:33
I'll steer our scale is also bigger.
22:34
We're about twice the mass and about.
22:37
So I think 60% Will thrust in an N 1.
22:41
So if you don't mind me asking here, why do you think Starship
22:44
will succeed using a similar? Even not just the multi-engine
22:48
Clause if you're anything like that.
22:49
But just even though General like test by flying philosophy
22:54
of the N1, why do you think there's four flights?
22:56
The N1 never made it to Stage separation.
22:57
Why do you think Starship will succeed in a with all the
23:00
comparisons that are similar to it?
23:05
We do have a production line that if it takes those ten
23:08
flights will do it, they would eventually have succeeded with
23:10
the anyone. They just decided that it was
23:12
too expensive to continue and they want to do other things.
23:15
So after they had those failures they and I guess it's probably
23:18
pretty embarrassing. Our national level, but I do
23:22
think that the Starship resign, if you've got a, you've got a
23:26
rocket with light engines as we do, if you have extremely good
23:29
engine isolation so that if an engine fails, it does not cause
23:34
The failure of neighboring engine or the stage itself, you
23:37
have a very robust design because then you lose one of 33
23:41
engines. That's a three percent thrust
23:43
lost. It's not a big deal, but if you
23:45
do not have good energy and isolation and an engine failure.
23:49
Can Domino to other engines or two parts of the stage?
23:53
Then you have an extremely unreliable design so that's why
23:56
with with recruiters haven't, but especially booster 9, we're
24:00
gone to so much trouble to isolate the engines.
24:04
And so if one engine goes wrong, it does not knock out other
24:07
engines or damage the rest of the stage.
24:10
Yeah, so I think it's when all is said and done.
24:13
This will be an extremely reliable provide, that you.
24:16
It's absolutely fundamental to achieve Edge isolation.
24:19
Hey, Alana to expect hls to be Starship.
24:22
Hls to be the long pole for our team is 3.
24:27
No, definitely don't. I think we will be will be.
24:33
The first thing to be really be, I think we'll know.
24:36
I think will be the that we will not be a limiting factor at all
24:43
you on. How much do you expect to spend
24:46
in this kind of prototype development phase?
24:48
Before one of these Starships actually starts flying real
24:51
payloads other and starlink or otherwise and how many kind of
24:54
tests are you targeting before that?
24:58
I hope all we can get. For flight to out the Seer,
25:03
maybe five and we should be. I would be surprised if we exit
25:08
this here without getting to orbit.
25:12
I'd say it's not 100, it's not hard.
25:13
Said probably. I think we probably got an 80%
25:16
probability of reaching orbit this year and pretty and I don't
25:20
want to tempt fate. You're not going to work but I
25:22
think close to 100% chance of reaching orbit within 12 months
25:27
Thank you very much like it's Basics, actually quite good at
25:29
production so we do like extremely like the best in
25:32
history of any rocket made from with production.
25:35
We're making a falcon 9 upper stage which is a large complex
25:41
machine every three or four days.
25:44
And around there every day right now.
25:47
Yes, we're capable of. We're actually slowed it down
25:49
slightly because we've got more Raptors than we know what to do
25:51
with. So we're actually focusing but
25:53
more on the rafter side on upgrades, mostly to improve
25:57
reliability and robustness of the engine.
26:00
They some performance improvements as well and the
26:02
cost of all this like how much do you expect to spend on all
26:05
that either this year or before you start flying real payloads?
26:12
Probably. Be a couple billion dollars this
26:16
year, two billion dollars ish. well, then on Sasha and there's
26:23
kind of a struggle by other companies to raise funds lately,
26:27
for a number of reasons in SpaceX is usually didn't
26:29
insulated from that. But do you see any kind of
26:31
difference, nowadays is SpaceX kind of thinking about
26:34
fundraising differently, and it does that affect how the
26:37
pressure on this Starship program at all?
26:40
We do not anticipate needing to raise funny.
26:45
We think we're we don't think we need to raise funding will do a
26:48
status thing where we provide liquidity to employees who are
26:51
in stock, but that's my knowledge, we do not need to
26:54
raise incremental funding for SpaceX.
26:59
Annie Lon. Another 5-10 minutes.
27:05
Okay cool. Yeah, time and didn't want to
27:07
get a be fun to get some new people in here, John Cross and I
27:10
haven't said anything yet and it also Mary Liz.
27:12
So John I saw you start to speak there for a second.
27:15
Yeah, I have a fun questions. The lean off the pad was that
27:18
intentional was it more than you thought?
27:21
It might be, was it related to the engines out and do you
27:24
expect to do that on future more operational launches?
27:29
No, we're not. We the it was related to the
27:31
engines out and we do not normally expect to lean.
27:34
It should be good. I asked for Ashley going
27:36
straight up, there will be some debate as to because you can.
27:40
So for the next fight we're going to start the engines
27:42
faster and get off the pad faster.
27:44
I think we're from started for engine start to actually moving
27:47
was around 5 Seconds which is really a long time to be
27:50
blasting the pad. We're going to try to get that
27:52
down to about half that time, maybe two and a half seconds,
27:57
start the engines faster and and then at throttle up faster and
28:00
just get off the deck and dark black reduce how much we blast
28:02
the pad and then there's a debate of do you keep the rocket
28:07
over the pad which case you there's more cooking of the base
28:11
or do you start you start moving sideways sooner if you move
28:15
sideways sooner you are moving that big cutting torch across
28:19
the launch room so you can think of a thing like the world's
28:22
biggest cutting torch basically And so it like we have big steel
28:27
plates over the top of launch ring.
28:29
But I think, depending on how close the engines are they are,
28:32
they are road that deal at a roughly in it.
28:35
I think. Half an inch to an inch per
28:38
second of high strength, high strength steel is eroded by The
28:43
Cutting torch, so you don't be too.
28:46
You want the entrance to be too close to the launch ring before
28:49
you. You start moving sideways with
28:52
it with the abyss doing that. What's the op?
28:54
Yeah. And on this one as it did move
28:56
across the launch ring because it needed out there sideways,
28:59
did it towards the top of the laundering to batter did?
29:02
I can't hold up pretty good. Actually held up surprisingly.
29:06
Well, so we actually we're glad to see that there's appears to
29:08
be minimal damage to the launch ring and to the components
29:12
inside launch rank. So, that's great.
29:13
Because that launch roaring is to take six months to build up a
29:18
new launch ring. We have some spares, but that
29:21
there's a lot of complex, Plumbing wiring inside launching
29:23
and that Apache appears to be in good shape.
29:26
Yeah, I just had one could question, speaking of that
29:29
launch ring, like, liftoff conditions.
29:31
Topic. Why couldn't you wait like a
29:33
month to install that steel plate for it to be ready?
29:37
My twin? Why launched before?
29:38
That's ready? As I said, we did a static fire.
29:42
Well, the booster with the concrete, the pond egg and we
29:45
saw mod a manageable amount of erosion.
29:49
We thought the launch would have increased erosion but would not
29:54
smash the concrete. So weird.
29:56
Not expectations, batch the concrete would not think I would
29:58
agree with that that would occur based on the data.
30:00
We saw from the static fire. If we thought that would occur,
30:03
then we would have waited for this deal.
30:04
The deal with was really meant not, it was, is intended to be
30:09
have a launch pad that requires minimal the basically no
30:12
refurbishment. That's the intent, the attached
30:16
of the sort of water cools, the mega steel sandwich and was the
30:21
communications blackout. The reason the staging event
30:24
didn't happen or was it, because it Didn't get that point started
30:28
tumbling before. Yeah, it just didn't get to what
30:32
I would consider to be a safe point to do stage separation.
30:35
Now, I should point out like stage.
30:37
Separation itself is a dodgy thing, and many, a rocket in the
30:39
past has as failed at stage separation, or putting a lot of
30:44
attention on like said, I don't get too confident but I feel
30:48
like it's really quite likely to get to Stage separation with the
30:53
next flight. And so then we want to make sure
30:55
that We actually execute the stage separation because it is
31:00
different from Falcon. It's yeah.
31:02
So that's we want to get through this stage.
31:05
Separation light the ship and complete.
31:09
What almost a full. Oh, but it's actually got the,
31:12
the Delta plus C is almost identical to orbit, but so we
31:17
actually could sell it to a decently good orbit, but we want
31:21
it, we want to test the entry system of the show so to test
31:24
the ship heat shield in the height, you so get to orbit and
31:27
then ideally deal with with the ship.
31:29
So we can test the how well the heat shield works for the ship
31:33
or one of the vehicle. Yeah, let's grab one more Mary.
31:37
Liz Bender. I can marry with solinsky.
31:40
Sorry. Yeah figure out how to change my
31:42
handle Iman. That that launch was so epic.
31:46
I don't know how you felt in Mission Control.
31:48
Maybe you were nervous and paying attention to data.
31:51
But for the rest of us that have witnessed years and years of
31:55
Falcon, launches and many other launches, I think it's safe to
31:59
say that was the most epic launch of them all.
32:03
And I hope you got a chance to really I enjoy it.
32:06
I was actually wondering about that moment in the room with
32:09
your team or maybe for you personally.
32:12
Like, how did this compare to the other first that you've gone
32:16
through in the Falcon program with hopper?
32:19
Like, how did you feel? Yeah, no.
32:24
I was very excited about the SpaceX team to amazing work and
32:28
aren't this is really one of the hottest technical projects that
32:32
Humanity has ever done. This yourself fully reusable
32:36
humongous rocket fully, and rapidly, reusable reliable
32:40
rocket, that of unusual size. But this is certainly a
32:46
candidate for hardest. Technical problem done by
32:49
humans. Yeah, look at little bit.
32:51
So I think the teams And excellent work at one, a very
32:56
hard problem. And I think we're actually I'm
33:00
upbeat about the next 12 months. I think we're going to get to
33:03
orbit and then the it'll probably take us a few more
33:06
years to achieve reuse reuse ability on a regular basis where
33:10
we bring the booster back and bring the ship back and where it
33:13
gets that, you know, take a few years to get to where Falcon 9
33:15
is today, where it is now quite normal for the rocket to land
33:20
every word. If it doesn't land these days.
33:22
So, it's in that Old. Yeah, it's crazy.
33:26
Hitting the bullseye of a ship out in stormy weather at that,
33:30
sugar is not. Anchored is literally trying to
33:31
keep position. It's holding to a GPS position
33:34
in. The rock is flying to that
33:35
position until manages to hit the bullseye in a storm.
33:38
Make it look you guys make it look so easy it's crazy every
33:42
time to watch that happen. Yeah.
33:45
Like that. It's a testament to the awesome
33:47
team and it is wonderful. Sorry, I just had one more
33:52
question. A lot of opposition from these
33:54
environmental groups in the area over the debris and I just
33:57
wanted to get your reaction to that since some didn't expect
34:01
the debris to go as far as it seemed to go.
34:02
And if there is a legal challenge in court, you know
34:05
either against SpaceX or the effort, how would SpaceX respond
34:09
and what would that do to the timeline?
34:12
Yeah, I think if you stop for practical purposes, what was?
34:16
I think? Like you, if you were to say
34:19
like at this point, I look at it aerial picture of the area and
34:21
apart from the area around launched and tell me where
34:24
things are damaged. It's actually, I think can't
34:26
even see it at this point. So the it's not like the rocket
34:30
uses non-toxic propellants and so it just got a lot of dust,
34:34
but it's the best of our knowledge.
34:37
Like there is not been any meaningful damaged.
34:41
Environment that we're aware of. And to be honest, I was out
34:43
there at the pad, two days after there's a huge storm on Saturday
34:46
like 70. 80 mile an hour winds, yeah, it was intense and like I
34:50
saw more debris coming off the shore from like people's Ducks
34:54
falling into the water and like capsized boats.
34:56
If that's true I did anything more than just some bits of
34:59
concrete which you know. Yeah yeah I mean to exceed the
35:04
Damage Done by a hurricane is quite difficult, hurricanes
35:08
nature, the power of nature is a man's compared to I will We are
35:11
still feeble compared to the power of nature.
35:13
Little tiny miniature. Hurricane Really tiny like I
35:16
look at Sasha pin slide. It seems so big to us humans,
35:19
but if you zoomed out and we're looking at Earth from a
35:21
distance, you wouldn't even see Starship it real I can't I think
35:24
I see a tiny little dot jumping off the surface.
35:27
Maybe yeah. It's like we're like microbes
35:30
trying to get from one dust mode to another dust mode.
35:33
Did you see the village of them by the way, like pad footage of
35:36
how like dark and crazy? It got it.
35:39
It does, it's crazy cause it looks so violent and wild.
35:42
It looks like a miniature tornado just for a minute. there
35:45
but at some of the footage is actually terrifying to imagine
35:48
if you were obviously no one's around it at the time but it is
35:52
not the amount of power that thing has yes, it's Yes, they're
35:58
actually we're really looking at the like the Retro throat.
36:01
We believe is the highest heat flux of any human-made object
36:07
ever. Well, how does it survive?
36:11
Is it helped that Plaza has to go through a throat?
36:15
Any, how does that throat? Not melt.
36:17
That's crazy. And literally, how does it from
36:21
a mastermind like film Cooling and regenerative doing?
36:24
Yes, keep getting cooled region. It's like getting crazy to regen
36:27
Cooling and like we're flowing. Liquid methane at extreme
36:30
pressure, 11,000 PSI through the jacket at clothes ripping and
36:35
then combine that with film Cooling and the best thermal
36:38
barrier Coatings, we can come up with but it's still shocking
36:42
that we do not favor eyes, the throat of that engine in
36:45
immediately, it's a heat transfer so insane, but that's
36:50
what we live on a planet with a lot it with strong gravity and I
36:53
freaked out. Sphere.
36:54
So it's this is what's needed. If we were to become a
36:58
spacefaring civilization and bold based on the moon and the
37:01
city on Mars and yeah multi-planet species which is I
37:05
think a super exciting future and at a high level the super
37:08
cool thing here is that hey this thing kind of works and we're
37:12
going to solve the issues that are remaining and we'll get it
37:15
to all good. And we'll make it reusable.
37:17
And that means that we have it a real path here to get Humanity
37:22
to Mars. It's also that's mind-blowing
37:27
Ilana. I want to let other people talk
37:29
here but I did want to say just on behalf of all of us, that the
37:32
production work that you guys put on like the actual show, we
37:36
all greatly appreciate it. I think that was like one of the
37:38
most amazing launch coverage. Has I've ever seen and I think a
37:41
lot of us were like hoping that you guys were going to give us
37:44
cool angles and you guys by far exceeded the expectations.
37:47
Yeah, I've greatly appreciate that.
37:48
I think everybody else does as well.
37:50
That sounds like you. You guys are most welcome and it
37:54
was a super appreciate your support and and always looking
37:57
for critical feedback and stuff supported critical feedback is
38:00
always extremely welcome. And at the end, thanks to help
38:03
bring the public along for the ride because the other day.
38:06
If we, the support of the public is essential and it's also about
38:10
inspiring the public that they're always, like, things
38:12
than world that are reasons to be like, sad about the future
38:15
and say, but you need, but there's got to be things that
38:17
you wake up the morning and inspire you and just be excited
38:20
about the future of life. And this is one of them and you
38:23
guys are key to conveying that to the public.
38:26
So, thank you. You guys are doing it for us as
38:27
well. So it goes both ways.
38:30
Just a quick question. Christopher - are you looking
38:35
for this next flight? Are you still deciding that one?
38:39
Because no 25 is that nice isn't it?
38:41
I'm done if you're going over 25 or 28.
38:45
I made a final decision on the ship, that's why I was referring
38:47
to Brewster nine. But I was somewhat, I did not
38:49
mention the ship number, I know. So it's a good catch there.
38:54
Yeah, I think we'll probably make that decision at this this
38:56
week, but I do we want, we do want to bet on success in the
38:59
sense that if we get to orbit, it will be super helpful that
39:02
try a deal good and see how well, the ship heat shield works
39:07
at you because we need to maintain control in Hypersonic,
39:10
High heating regime. Then get through transonic and
39:12
then maintain control away. Through a very wide array of
39:19
micro regimes and so the vehicle actually behaves differently
39:24
with a radically different Heating and force at the various
39:26
mcroy coming back from like, roughly Mach 23 20.
39:30
Yes, we do. I think we want to have that
39:32
option. So I think we'll put a chiffon.
39:34
That gives us that capability, but we haven't decided exactly
39:38
what tripping over it should be. Hey Ilan.
39:41
This is a Michael sheets to CNBC quick question.
39:44
On the launched, our side of things.
39:46
Have you catalogued damage to the equipment?
39:49
It looks like some of the tanks were hit by debris and there's
39:53
quite a lot scattered around. Do you know can you give us like
39:56
a rundown of what you guys need to replace versus repair?
40:00
We're going to be replacing a bunch of the tanks in the tank
40:03
farm, but these are tanks that we want to replace.
40:05
Anyway, so the we're going with more of the vacuum jacketed
40:10
giant, hot dog looking tanks. As opposed to the solute.
40:15
Yeah, vacuum decade of giant hot dog tag, so that those are in
40:19
the best shape and those are what we want.
40:21
Anyway, so some of the tax will be yet but probably removing and
40:24
replacing with the hotdog tanks. The tower itself is in good
40:28
shape. We see you know, Now ready for
40:31
damage to the tower even though to get hit with some pretty big
40:34
chunks of concrete. And yeah, then likes it will be
40:37
installing the big water but a jacketed still sandwich thing
40:40
under the pad of doing final prep on the next Brewster and
40:43
ship and hopefully be ready to fly again in a couple months.
40:47
Once again, excitement guaranteed success is not, but I
40:50
do think I'm cautiously optimistic.
40:53
I think we've got this time. We've got a better than 50%
40:55
chance of reaching orbit, so that would be incredibly
40:59
exciting. Is that steel plate.
41:01
The only thing that you guys are implementing to reduce the
41:04
amount of debris that gets everywhere or is other other
41:07
fixes that you're considering to fix that, but there's a bunch of
41:11
other things were doing. So this gave you a lot of Steel
41:15
plating with. So not just underneath the
41:17
directly underneath the, the rocket, but also extended beyond
41:20
that and also tying the whole structure in together with the
41:23
legs which, which goat that those legs go down very deep and
41:27
then just in general what we want to have.
41:30
Launchpad that over time requires a no refurbishment
41:35
between flights, and that means, obviously not throwing out
41:38
chunks of concrete rapidly, reusable rockets and reusable
41:42
launch pads. Exactly.
41:45
Yeah. Totally on the launch site
41:47
itself, it looks like it's little little bit off the pad
41:50
instead of going like straight vertical, like Falcon does, was
41:53
that part of the profile or was that because the engine
41:55
failures, that's because engine failures.
41:58
Yeah. All right I better sign up now
42:01
but will be I'll do another update.
42:03
Once we resolve some of these questions, I'd be exact
42:06
configuration of the next flight and the upgrades to the launch
