Elon Musk Discuss The SpaceX & Starship! One day we occupy Mars. · Elon Musk Thinking

I far, and the achievements of the past year demonstrate that, I think
0:04
to a degree that is mind blowing. Like what you have achieved over the
0:07
past year is nothing sort of incredible, and one day we will indeed occupy
0:13
Mars. So let's go through everything that FACEX has achieved, that you have
0:17
done, and it's actually going to take a while. By the way,
0:21
this is going to take a minute. First of all, with Falcon we
0:23
have achieved the most launches of any rocket in a single year ever. So
0:28
the next best is was the Soviet Soyuz, which I think did a little
0:31
over sixty launches in a year, and we did ninety six. Yeah,
0:35
so no other family of orbital class rockets has launched more than sixty three times
0:39
a year. That was Soyuz, and we did thirty percent more. Falcon
0:42
Heavy also surpassed in terms of heavy lift vehicles the record for Saturn five,
0:45
which I think that with five launches last year week seeded the Saturn five records.
0:49
So that was like pretty incredible on Falcon Heavy. So this gives you
0:53
a sense in pictures of how incredible that was. For a while there I
0:57
was like when I was like I'd be posting something, is this like the
0:59
launch that just happened or the one that is happening, or like because they
1:02
were like three launches that happened in the space of a few days. But
1:04
this is all the launches on one page. And yes, it's really incredible.
1:10
All made it to orbit, all landed, just a huge hand for
1:12
the Falcon team. That was incredible. And two those of the missions were
1:15
Starlink, but the third were for other customers for a NASA for other communications
1:21
satellites. It was a combination of our of Starlink plus a lot of other
1:26
missions. So even if you just take the non Starling portion of the flights,
1:29
that was more than any other vehicle. Last year by a long shot.
1:32
We launched NASA's Psyche, Issa's Euclid, the X thirty seven B spaceplane,
1:38
multiple transport emissions, we launched, did missions for one web Viasat,
1:42
and we're actually on contract to launch Amazon's hyper Constellation and we treat everyone fairly.
1:47
So just one and just and we managed to do nineteen flights on a
1:51
single Falconine booster, which is really incredible in three and a half years.
1:55
So and that vehicle did that. Brewster did eight hundred and sixty satellites and
1:59
deliver two undred sixty metric tons to orbit. Because it's like wow. So
2:01
there's a lot of wows and it's worth you know, like, how long
2:07
ago was it that we landed a booster? Was actually eight years ago in
2:09
December, roughly eight years ago, and since that time we've landed two hundred
2:14
and sixty times. The two hundred and sixty landings, it's just like wow.
2:17
There were a lot of people that said that it couldn't be done,
2:21
and then there were a lot of people that said, even if it could
2:23
be done, it's a dumb idea that it wouldn't it wouldn't pay off,
2:25
that it wouldn't you know, it wouldn't make sense. But we've shown that
2:30
in fact, it is absolutely the right. Idea of reusability is the key
2:34
to a great future in space. It's essential. We need reusability for truck.
2:38
It's just like we have reusability for cars, for airplanes, for bicycles,
2:42
for horses. Obviously, reusability is essential, and the fundamental invention that
2:46
is necessary for humanity to become a multiplanet species is a full and rapidly basically
2:53
rapidly reusable, reliable rockets. I mean, it's incredible how much has happened
2:55
in eight years. I wonder what will things be like eight years from now.
3:00
Hopefully we have I think we will have landed on Mars, and I
3:02
think we will have sent people to the Moon, and maybe if we get
3:06
like we will have sent people to Mars within eight years. The key question
3:08
is, sort of I think about for civilization is the key test perhaps for
3:15
civilization is do we make it through the Spermi Great filter of being going from
3:19
a one planet civilization to a multiplanet civilization? And if we are, if
3:22
we do become multiplanet civilization, we may go out there to other star systems
3:27
and discover many long dead one planet civilizations. And we don't want to be
3:30
one of them. That's lame. We don't want to be one of those
3:31
lame one planet civilizations. But I think we should always regard civilization as fragile,
3:38
as not something that not a situation where there is an inevitable upward trajectory.
3:43
I mean, I read a lot about history, and if you look
3:44
at if you read history, you see that civilizations are anything but permanent.
3:49
Many civilizations have risen and fallen over the years, over the centuries and millennia,
3:53
and eventually the Sun will expand well the oceans and destroy all life on
3:58
Earth now bitterly. That's you know, several hundred million years in the future,
4:00
but it's only about maybe ten or twenty percent of the existence of Earth
4:06
itself. If Earth is four and a half billion years old, then another
4:10
ten, ten twenty percent longer and life wouldn't or intelligent life would not have
4:14
evolved because it's taken us a long time to get to this point. That's
4:16
really that's really the key test. Do we become a self sustaining multiplanet civilization
4:21
while civilization still exists, or don't we that? You know, I think
4:25
that's really the key question. I think we've got a good chance, but
4:28
it's not a sure thing. That's why time is of essence. I think
4:30
we want to make Mars self sustaining as quickly as possible. It's not just
4:35
a question of getting people tomorrows, but it's getting enough tonnage and equipment to
4:40
Mars to make enable Mars to be self sustaining. The key test being that
4:45
if the resupply ships from Earth stop coming for any reason, do we does
4:49
Mars die out or does it continue? That's the really the fundamental threshold to
4:55
pass the Fermi paradox, great filter. The Fermi paradox is where are the
4:59
aliens? You know, if life is common, if intelligent life is common,
5:01
shouldn't we see a lot of evidence of it? Now? I get
5:04
asked a lot about, you know, aliens actually, and I usually say
5:09
I am one. Well, actually I used to be. According to you
5:11
know, Homeland Security, it's an alien registration card. Literally. I was
5:14
like, okay, but the truth is I actually have not seen any evidence
5:17
of aliens, which I think is maybe a bit more troubling than if I
5:21
had. I have not seen any, and I'd be on it and you
5:26
can pretty much guarantee that I would post about it instantly. Okay. I
5:30
was like, yep, let's we go one. This is a spaceship for
5:32
sure, But I have not seen anything. So that leaves me to think
5:35
that we're more likely to be a tiny candle of consciousness in a vast emptiness,
5:41
a vast darkness. You know that the civilization that we have is really
5:44
just this very small candle in a vast darkness, and we just must do
5:46
everything possible to ensure that candle does not go out. Yeah, anyway,
5:49
I think we can do it. So, you know, but we need
5:53
to move fast because you just never know. I mean, there could be
5:56
you know, at any given point. There's like Stephen Hawking actually I believe
5:59
said that he thought there was like roughly a one percent chance in any given
6:01
century of civilization ending. That was his rough estimate. I think it actually
6:05
might be higher than that. So we just want to go there fast.
6:09
So this is the getting back to Falconine, back to reality. These are
6:13
all the launches we've done, and you can see how the cadence of launches
6:16
has rapidly increased over time. I think people online have actually assembled videos showing
6:21
every launch and it just gets like crazy fast as you get to twenty twenty
6:26
three. Yeah, so we've done a nineteen three flight. We're now qualifying
6:29
Falconine to be able to do forty flights, and we're aiming for maybe as
6:32
much as one hundred and fifty flights this year. So and then let's not
6:35
forget far and recovery because actually a lot of people don't realize we recover the
6:40
fairing as well. This was actually very difficult to recover the fairing, so
6:44
cas an immense amount of effort. We now quite regularly recover the fairing and
6:47
we've reflown fairings three hundred times, so congrats to the ferry recovery team.
6:51
That was actually pretty damn hard. Oh and then of course we do operate
6:56
basically a small navy. I think people don't always know that, but we
7:00
have, you know, drone ships and support ships of various kinds. So
7:03
we've got a small fleet of ships and we operate them very efficiently. May
7:09
help people. Also, sometimes I don't know the site, Like you can
7:11
see the size of the ship by the person walking around on it. It's
7:14
not small, so it looks cool like that's sort of kind of a Darth
7:17
Vader aesthetic, but it's like it So, and we're also getting much better
7:20
with the pad turn around. We achieved a three day pad turn around and
7:24
I think we're aiming to hopefully get under twenty four hours pad turn around by
7:28
the end of this year. So in terms of yeah, launch rate.
7:30
Yeah, So it's been fifteen years since flight one of Falcon one, I'm
7:34
sorry, Flight four Falcone the first one to reach orbit. So fifteen years
7:39
since we've got anything at all or to orbit. Yeah, and now we're
7:42
aiming to have one hundred and fifty flights of thereabouts this year, so big
7:48
rockets at this point, Falcon one is little rocket. In fact, when
7:51
I see Falcon one right now, I was like, man, I think
7:54
I've probably tucked that under my arm and just take it home with me.
7:56
You know, it was like launched in the backyard or something. It looks
7:59
so cute. At the time, Falcon one did seem like extremely it was
8:01
extremely difficult. It took us four flights to reach orbit, and it did
8:05
seem kind of big at the time. But now it's like, you look
8:07
adorable thing. Yeah. So the most I think the most profound metric,
8:11
or the metric that really describes the magnitude of what SpaceX achieved in twenty twenty
8:16
three is the mass to orbit number. So and you can see the incredible
8:20
change just year of a year. So twenty twenty one we were slightly below
8:24
the rest of world. Twenty two we I think roughly doubled what the rest
8:28
of the world did. And last year we were eighty percent of all mass
8:31
to orbit. So the rest of the world, we mean like the rest
8:37
of US industry, you know, Europe, India, China, Japan,
8:41
everyone, So there's not a lot of industries where a company is doing like
8:45
eighty percent of everything. And then what's really mind boggling is that that number
8:50
should increase by fifty percent this year. So I guess on the order of
8:54
like ninety percent of all master to orbit, not counting starships. So if
8:56
we start as we start launching Starship, Starship is like in roughly one hundred
9:00
tons to orbit with every flight. There's a path to getting Starship to do
9:05
over two hundred tons with full reusability, So two hundred tons to useful orbit
9:09
with full reusability. And yeah, it's really an incredible amount. Twelve hundred
9:13
tons of useful load to orbit last year. Yeah, that's just astounding.
9:16
So I think that that really deserves around the floors. I got like wow,
9:20
I mean, that's the most mind blowing and the rate of increase is
9:22
just astonishing. Now these numbers will actually look very small in the future.
9:26
In order to build a city on Mars will need to be kind of in
9:31
the million ton to orbit range, so maybe a little higher, ideally a
9:37
little higher, but sort of if you just try to get things to the
9:41
right order of magnitude, like not trying to get to an exact number,
9:43
but try to get the order of magnitude right. I think it's on the
9:46
order it's roughly a million tons to Earth orbit. That'll get you roughly two
9:50
hundred thousand tons to the surface of Mars. So roughly, you know,
9:54
approximately twenty percent of what if you get to Earth orbit you can get to
9:56
the surface of Mars, and figure like, maybe we need at least million
10:00
tons of useful load to the surface of Mars for this for it to become
10:03
self sustaining. That self sustaining threshold is actually a very tough threshold to meet
10:07
because even if you're missing a tiny thing, then eventually that Mars will die
10:13
out. So you've got to be able to not just build, for example,
10:16
computer chips, but you need to be able to build computer chip factories,
10:20
because you can't build computer chip factories. The factory that you do build
10:24
will eventually break down and then you will have no chips, and then you're
10:28
that's it. It's kind of like a long sea voyage where if you're just
10:31
missing vitamin C, yeah, you'll cruise on for a while, but then
10:35
you know, you'll teeth will fall out and you'll die. That was a
10:37
real problem in the old days. Anyway, it's quite a high threshold,
10:39
is and like Mars, Mars is a fixer upper of a planet. You
10:43
need some work. But so it's not like you can just run around outdoors
10:46
and like you know, fish or live off the land. You know,
10:50
you can't live off the land on Mars. So it's really quite a lot
10:52
of work that's required to make that work. So Dragon an amazing amount of
10:58
progress with Dragon and a track record of success. So by as of last
11:01
year, the Dragon's fleet time on orbit exceeded the Space Shuttle fleet. So
11:07
we had accumulative thirteen over thirteen hundred days of time on orbit last year as
11:11
of last year. So that's pretty mind boggling that Dragon has now had more
11:15
days in orbit than the entire Space Shuttle fleet. It's like wow, So
11:18
yeah, and we've had now Dragon has visited the Space station more times than
11:22
the Space Shuttle as well. This is an incredible achievement by the Dragon team.
11:26
So once again, as I'm saying, this really has been an incredible
11:30
maybe the best year in company's history. I mean, it was the best
11:31
year in the company's history. Actually, So there's a lot of great things
11:33
to go through. And I'm not one who gives out false praise, so
11:37
it's really mind boggling what you've achieved. All of the missions. Last year,
11:41
I used a flight proven Dragon, so these were all these are all
11:46
these Dragons are all flown before, and this year we're looking to fly maybe
11:50
seven or eight Dragon missions. So it's really been fantastic success by the Dragon
11:54
team. This doesn't have audio, there's no sound in space. Yeah,
11:56
it's a great that's a great look in spacesuit and in Dragon interior. So
12:01
yeah, so we've now sent forty two humans to orbit. To be precise,
12:03
space is relatively easy, but orbit is very difficult. So if we've
12:07
now taken forty two humans to orbit and back, and I have to say,
12:11
like, yeah, if there's one thing I wish for, it is
12:13
that we bring them all back safely. That's like peeple like say, well,
12:16
what is the one thing you wish for? I said, I wish
12:18
we'd bring this asminalts back safely. That's one thing if I had one wish,
12:22
that's what it would be. So and we also have now completed a
12:26
second crew arm in Florida. So we've got two towers that are capable of
12:31
two launch pads that are capable of sending astronauts to orbit, and this is
12:35
going to be great for being able to shift missions between Pad forty and Pad
12:39
thirty nine night we've got so this here our first space walk, and so
12:43
we've got to redesign the suit so that you can actually move around in it,
12:46
and you don't just like, you know, because if you just inflate
12:48
the suit, you know, you just basically, you know, you're kind
12:52
of like one of those like balloons at a party or something, you know.
12:54
So it's it's quite hard to make the to still be mobile in an
12:58
inflated suit and have the joints move and stuff. And then we will actually
13:03
evacuate the whole spacecraft, so everyone, even those that don't go on the
13:07
space walk, will still be in vacuum. So obviously very important that at
13:11
work and we don't have like a little hole in the suit or something go
13:13
up and around. So but I think, you know, obviously we're gonna
13:16
put a lot of testing into this, and there's gonna be another significant milestone,
13:18
which is to have a suit where you can be in like the vacuum
13:22
of space with just nothing at all and just be out there. It's hard
13:26
to it's actually hard to conceive the concept of nothingness. And it's not technically
13:30
nothing like this small number of particles per cubic meter, but it's pretty damn
13:33
close to nothing. If you lose too much, too much air, too
13:37
much oxygen, that's it. There's no place to get oxygen from. So
13:41
like an airplane, even at high altitude, can increase, it's the pressurization
13:45
pumps and get more atmosphere from. Because in the atmosphere dragon springs an oxygen
13:50
leak, and that auction leak is too significant. There is no place to
13:52
get oxygen. You're just gonna die. So the requirements for getting everything perfect
13:58
are saying it's everything's going to be absolutely perfect to work. We did not,
14:01
you know, evolve to live in space. Obviously a tough one,
14:05
but this is really going to be another great milestone is to actually have be
14:09
able to have someone floating out there, you know, in the vacuum of
14:13
space and come back. And we do want to actually have we want to
14:16
have a space suit that you can walk around in because if you're on the
14:18
Moon, you're you want to be able to walk around the Moon, walk
14:22
around a Mars. So having a high mobility space suit that actually isn't crazy
14:26
expensive ideally and that you can walk around in comfortably is a big deal.
14:31
It's actually an important thing that needs to be developed and ultimately made in large
14:35
numbers, because if we send say a million people to Mars, then that's
14:39
a million space suits, well a million marsuits that you need, So we'll
14:41
have to make a lot of these things and we're atill more Starlink on that
14:45
flight. So then coming to Starlink, this is a this is only a
14:48
whole separate company, but we're basically building rebuilding Internet in space, which is
14:52
pretty wild and now it is I want to have size supplemental to the terrestrial
14:58
Internet. Sometimes people think, well, Starlink just going to take over and
15:01
destroy all the terrestrial Internet, like it definitely will not. But what it
15:03
will do is Starlink will give access to the Internet to people that either don't
15:09
have access or where their access is extremely expensive or very bad access. So
15:15
this is a massive enabler for improving and enabling people in remote locations to learn
15:22
anything like you can basically learn almost anything for free on the internet right now,
15:26
Like for example, MIT has all of its lessons on YouTube. You
15:30
can learn almost anything if you've got an Internet connection, But if you don't
15:33
have an Internet connection, you're limited to I guess book, you know what,
15:37
maybe you've got some books or something. But it's a basically starlink is
15:39
a game changer for improving people's quality of life around the world. Like it's
15:43
this might be the single well, certainly one of the I think it might
15:48
be the number one might over time technology that improves people's standard of living around
15:52
the world. It's certainly a candidate for potentially being the most profound thing that
15:58
actually improves quality of life for people around the world, which would be really
16:02
something to be proud of obviously. See and we're now introducing the V two
16:04
minis. This is the next generation satellites that we've introducing the constellation. And
16:10
yeah, these are twice the capacity of last year or so, from eighty
16:12
eight terribuits per second to one hundred and sixty five. And our goal,
16:18
the biggest, single goal for Starling from a technical standpoint, is to get
16:21
the mean latency below twenty mints, so that would that actually makes it's for
16:26
immediacy of for actually the quality of Internet experience. This is actually a really
16:29
big deal. Also, if you play video games like I sometimes do,
16:33
this is also important otherwise you lose. So this is anyway, so that's
16:37
actually a very hard problem. But because we're low with orbit constellation, the
16:41
speed of light is what do you think the speed of light is three hundred
16:44
kilometers per milesecond, So if we're at five fifty kilometers, figure it like
16:48
roughly two milliseconds up, two milliseconds down. So if you go up,
16:52
down, up, down to eight milliseconds speed a light limitation and then almost
16:56
everything else we can actually address, like we can't go fast those of light
17:00
yet, you know, but noah, probably ever, but we can get
17:03
the rest of the time I think below blow ten milliseconds and so then basically
17:08
it'll be a more responsive than ground internet in most cases, which is really
17:14
what we're after here. So yeah, this is really amazing work. We
17:17
also have now launched the Argone hole thrusters, which are very low cost and
17:22
use Argone, which is plentiful. So we've gone from using Krypton, which
17:27
is not that rare. I mean if Superman did come here and be like,
17:30
you can get some krypton, you know, and squirt gun or something
17:33
like that. Okay, now what krypton is a noble gas. That is,
17:37
it's moderately rare, But we would actually be using a huge percentage of
17:41
the world's krypton if we were launching that with the Gen two satellites. And
17:45
so we moved to argon and ar gone Is is actually extremely plentiful. In
17:48
fact, right now you are breathing approximately one percent argon, So ar gone
17:52
Is there's a lot of argne. But this is really the I think,
17:56
the first significant argne whole thruster and certainly by far the most cost efficient and
18:02
most power efficient, and a really great job by the Starling team to create
18:06
this thruster and many other upgrades to the in space laser stuff. I mean,
18:11
so this is by far. I think we're now sent at least one
18:15
thousand times more data, maybe ten thousand times more data over laser links in
18:19
space than any other system before. I think it will soon be like a
18:23
million times more data transferred, maybe more than that through the starlink laser interconnects
18:29
between the satellites. So we now have nine thousand active space lasers, so
18:32
sort of vaguely reminds me of Doctor Evil, you know, lasers from space.
18:36
Actually, well, I guess I made that joke a long time ago.
18:37
It's like Dragon does have light. Art has like a laser for you
18:41
know, document the space station. So like dragons with lasers, I mean
18:45
like it'd be better than shocks with lasers. And each link, each laser
18:48
link is capable of one hundred gigabus per second and we're looking to increase that.
18:52
So let's see. This is an animation of all the places where starlink
18:56
is active. So obviously a lot of the Stallink activations depend on country approvals.
19:00
So as we are able to get a country approval, then you see
19:03
rapid adoption within a country, and hopefully we'll get to most countries. Most
19:07
of the rest of the countries will get the approval hopefully this year, and
19:11
we'll be able to go almost worldwide. Some countries are probably unlikely to approve
19:17
our system, but most countries we think we should be able to get to,
19:21
and our goal this year is to activate service in more than half of
19:23
the world's population, so that would be every fantastic but I do want to
19:26
emphasize because we are going to put this presentation online, is supplemental to terrestrial
19:33
internet, does not replace it. So it does really well for low population
19:41
density areas, but it is really not going to be competitive in high density
19:45
cities or it's really low density situations, which is really where the need is.
19:51
So anyway, it works well with other Internet providers, is what I'm
19:55
saying. Then we've got community gateways. I'm told this is a town called
19:57
Analaska's a real place. So we're a lot more gateways down as we increase
20:03
the number of gateways. That improves latency. We've now shipped our next gen
20:06
hardware that's version four of User Terminal, so that allows us to lower the
20:10
cost of Starling. And we'll be introducing the stalling many later this year which
20:15
can fit in a backpack, so that'll be pretty cool for anyone who wants
20:18
very portable Starling. And then we just opened our stalling factory in Bashrup,
20:23
Texas. So that's just a little you know, about twenty minutes away from
20:26
Houston. And this is this is gonna be. Yeah, I guess some
20:30
of you guys are part of that. Yeah, in general, we're gonna
20:33
We're gonna have like a massive round of applause for Starling, that is for
20:37
sure, because it's like the achievement level there is amazing. Actually, let
20:40
let's just have a mass around a flow. It's like, goddamn, it's
20:42
hard to clap with this thing. Yeah, this is the stalling achievements are
20:45
really mind blowing. So it's like the stalling system is an anomaly in the
20:51
matrix. And then we also just recently launched our first director sell satellites,
20:56
and we were able to send text messages directly from a phone to the satellite
21:00
and then back down again. So we did intentionally bespell these things, by
21:04
the way, So although actually when I first saw it, I was like,
21:07
is this real? Be terms that is in fact real? This is
21:10
yeah some doze cooin jokes basically, so yeah, And anyway, so it's
21:14
kind of amazing that you can actually close the link between a phone in your
21:18
hand and a satellite that's hundreds of miles away, and the satellite can hear
21:22
the tiny signal that your phone is outputting, which is like such a faint
21:26
whisper it's ridiculous, but it can actually somehow hear that faint, whisper and
21:30
be able to communicate with a phone. Is I think it's one of those
21:34
things like I would say, is that actually physically possible? But it is
21:37
now I do want to size this is also a not a competitor to phone
21:42
companies. This is something that will be supplemental. So it's going to be
21:45
very helpful for remote areas where there's no cell connectivity, or once in a
21:49
while within a city. If there is a place that has no connectivity within
21:52
a city, then Stonik will be able to communicate with phones. But it's
21:57
I think it's something on the order of seven megabus per second within a cell,
22:02
and the cells are hundreds of square miles or kilometers in size, so
22:06
it's really it's good for text messages. You could technically do video if you're
22:11
the only one or if there's only a few people in that cell, like
22:15
if you're in the middle of the Pacific or something like that, then but
22:18
it is something that is going to be very helpful and well I think save
22:21
lives of people. You know, if somebody's sort of hiking in a remote
22:23
region and they get lost, well, now their phone could actually work,
22:27
and it could I think it will actually save a lot of lives, which
22:30
is cool. And then we have seven announced partnerships. So we've got T
22:33
Mobile in the US, Rogers in Canada, Optists in Australia, one New
22:37
Zealand, Assaulting in Switzerland, KDDI in Japan, and Intel in Chile and
22:42
Peru. So and we expect to announce a number of other telco partnerships this
22:47
year. So this is definitely something where we're again in partnership with telcos.
22:51
I just basically don't want Telcos to get really mad at us. That's what
22:53
I'm what I'm saying, you know, we want to be support to telcos.
22:56
And then of course this is slow down a little. But that launch
23:00
did take a while to get off the pad that took off, I was
23:03
like, wow, I can't believe it took off as my reaction. So
23:07
it gets incredible that we took off twice last year. Even though I've been
23:12
very you know, closely you know, involved with the Starship program from the
23:17
beginning and actually like I lived out here, this is my primary residence for
23:19
three years. This used to be a sandbar basically what we're looking at here,
23:23
and now it's got an advanced rocket factory and a gigantic launch pad,
23:27
and we've got a whole bunch of rockets out there. But I still amazed
23:32
that it actually got put together and it took off. I'm like, wow.
23:36
I mean, the starship is more than twice the thrust of a Saturn
23:40
five. It is by far the biggest flying object ever made, and for
23:45
you know, with with some upgrades down the road, it'll actually be I
23:48
think probably over twenty million pounds of thrust and Saturn five is seven and a
23:51
half, so it'll end up being three times to thrust a Saturn and it's
23:55
gonna fly a lot. It has to fly a lot, so it's gonna
23:56
end up flying several times a day from many different locations in the world.
24:00
And I think there's a pretty good chance that it does Earth to Earth transport
24:04
as well, because the fastest way to get from one place to another on
24:07
Earth is you know, to get from here to the other side of Earth
24:10
is an intercontinental ballistic missile, but just make sure you delete the nuke and
24:14
add the landing part. Basically it's the fastest way to get somewhere. Yeah.
24:18
Wow. And then between flight one and two, we made a number
24:21
of massive upgrades. So the it was obviously a massive upgrade to the launch
24:25
pad. So we've got like in many Niagara falls, here, the water
24:27
pressure is so much that if it went straight up, it would actually destroy
24:32
the rocket. That's how much water pressure it is. So it's like wow,
24:34
and it worked like actually it went looked at. One of the first
24:37
things I went looked at after the second launch was to check out the launch
24:41
pad because obviously after the first launch we dug a pretty big hole and and
24:45
honestly, it looked like you could just it looked like there was no damage
24:48
at all, like you could just launch a game basically for the pad itself.
24:52
So it's great work by the team to radically improve the launch pad overnight.
24:56
People always like want to use the Statue of Liberty for stuff. Statual
24:59
Liberty is not that big. I was like, I was like, been
25:00
there. I actually climbed up the Statue of Liberty in the tiny staircase a
25:03
long time ago. But anyway, this is a big rocket and we'll get
25:07
bigger over time. Yeah, so that's I don't know, if you guys
25:10
watched the cong versus Godzilla, it's like one of the most insane movies I've
25:14
ever seen, but it's like kind of entertaining and it's sheer madness. And
25:18
the crazy thing is that that a launch tower is bigger than Mecaso and it's
25:21
gonna do basically like the same thing, but with the arms, you know,
25:23
catch the rocket and tell people like, yeah, we're gonna catch the
25:26
largest flying object ever with giant mechanical arms. They're like, there's no way
25:32
that's real. I mean, we could give it legs too, just give
25:34
it legs and have it drump around. That'd be pretty cool. And then
25:38
we're also gonna build the second tower. Uh yeah, this is We're gonna
25:45
really be launching a lot and up and we're gonna be upgrading one tower while
25:48
we launched from another tower. So two towers is important, and there was
25:52
there are actually so many upgrades between flight one and two that it would actually
25:56
take it like hours to go through the mall. But one of the biggest
26:00
upgrades was going from a hydraulic to electric of the engines, so that actually
26:06
saved a lot of mass and complexity. So yeah, the electric TVC,
26:10
I mean, it was just that this is one of the biggest upgrades we're
26:12
also massively upgraded the heat field. The engines themselves were massally upgradedally, literally
26:17
everything on the rocket was like there might have been thousands of upgrades between flight
26:22
one and two, so really gigantic improved between flight one and two, and
26:26
also obviously many improvements between flight two and three. And then we've got a
26:30
whole development plan to, like I said, ultimately get to a fully reusable
26:33
rocket that does over two hundred tons to orbit on a regular basis, full
26:37
reusability. Yeah. Hot staging, I mean, hot staging was a change
26:41
that was basically, I don't know, I just really within the space of
26:45
like three or four months maybe less, going from or roughly that, going
26:48
from previously just separating the rocket without anything to actually lighting the upper stage engines
26:55
while the first stage engines are still thrusting and not blowing up the ship,
26:59
which is that was an amazing achievement. So I was like, Wow, that's an
