Inside Starcloud’s $2B Space Factory

Molly O'Shea tours Starcloud's Redmond, Washington HQ with CEO Philip Johnston, who argues that below $500-per-kilo launch costs, space-based AI data centers beat terrestrial ones. Starcloud went founding-to-orbit in 21 months, launched the first Nvidia H100 in space for about $2.5 million versus a $75-100 million quote, and Starcloud 2 launches in January with 100x the power. Co-founders Ezra Feilden and Adi Oltean explain the rescued secondhand vibe table, in-house radiators and cooling, and chip burn-in against radiation. He covers edge inference for government imagery, an 88,000-satellite constellation totaling 10 terawatts (20x the US grid), and the $450M raised. He predicts SpaceX will buy Tesla and top $100 trillion, plus a Fermi Explorer mission reaching Alpha Centauri in 80,000 years.

Molly O’Shea0:00

We're with Philip Johnston, the CEO, and we're going to go through the $2 billion company and what they're building behind us.

Philip Johnston0:07

That's the satellite we launched in November last year, with the first Nvidia H100s on board.

Starcloud 1, separation confirmed.

Philip Johnston0:14

They told us it would cost $75 million to $100 million to do Starcloud 1. We did it for about $2.5 million. If the launch cost gets below around $500 a kilo, then it will be much cheaper to do this in space than terrestrially.

We think we can fit about 10 terawatts in this dawn-dusk sun synchronous orbit, so that's about 20 times the entire U.S. power grid.

Ezra Feilden0:31

It's around 2 tons, fully loaded, 235 kilowatts, and we can deploy up to 50 of them per Starship launch.

Molly O’Shea0:37

Do you think Tesla will merge with SpaceX?

Philip Johnston0:40

This isn't a hot take, this is just a fact. SpaceX is going to buy Tesla.

Molly O’Shea0:54

We are here at Starcloud in the Seattle region. I'm not going to disclose the exact location because it's a secret,right, Philip?

Tour begins1:00

Philip Johnston1:00

Top secret.

Molly O’Shea1:01

Top secret, okay. We're with Philip Johnston, the CEO, and we're going to go through the $2 billion company and what they're building behind us.

Philip Johnston1:11

So welcome to Starcloud. On the screen we actually have the location of Starcloud 1, so that's the satellite we launched in November last year with the first Nvidia H100s on board. This little green area is everything that's visible anywhere on Earth where you have line of sight to the satellite, because it means if we have ground stations anywhere in this green area, we can see the satellite.

It's moving about 17,000 miles an hour, so it takes about an hour and a half to circumnavigate the globe. So if we come back in half an hour, you'll probably find it over Africa somewhere. Yeah, it's moving fast.

Molly O’Shea1:43

And before we walked over here, it was down here. Something special happened over here?

Philip Johnston1:48

Oh yeah, yeah. So it actually just came over Cabo, which is where I proposed to my fiancée, and it only comes over there once every three days. So I waited till 6:00 a.m. and then showed her on the phone because I'd written the proposal on Starcloud 1.

Molly O’Shea2:01

Yeah.

Philip Johnston2:01

So yeah.

Molly O’Shea2:03

It's cute. Check out the post if you haven't yet. Okay. Allright, so we're going to walk through the facility. Just give us, like, a sense of what we'll be looking at, what stages of development. Are we going to see Starcloud 1, Starcloud 2, maybe Starcloud 3 anywhere close?

Philip Johnston2:18

Yeah, well, so Starcloud 1 is launched. Starcloud 2 we have in the assembly facility. As I say, it's we are this is midway through move-in, so please take it with a pinch of salt for those boxes everywhere. And then we'll go through to the fab shop.

We've welded up a mock-up of the chassis of Starcloud 3 so you can get a sense of how big it is. And then we'll go through and we'll finish the tour in some of the newer facilities that we're bringing online next year.

Molly O’Shea2:43

Awesome. Cool.

Philip Johnston2:44

Cool. This is the main assembly area for Starcloud 2, and this is the satellite in the background. You can see Starcloud 2. You can see on the top the two lasers, and then we have some deployables. It's about a 120-foot wingspan deployment.

And we actually just put this through vibration testing, so this is our vibe table here. Fun story about this vibe table is we we we actually had I'm going to move around here so you can see it. So we couldn't find a vibe table in the U.S.

Vibe table saga3:01

Philip Johnston3:18

that would vibe with a pressure vessel on there in the time we needed, and the lead time on new vibe tables is about, like, almost two years now.

Molly O’Shea3:26

Oh no.

Philip Johnston3:26

Yeah, so and it's about $1.5 million for a new vibe table. So we actually bought this secondhand broken vibe table for 200 grand, and then the team worked all weekend to fix it up. I don't know if you can see maybe we can go around and you can see how janky, like, the amp that we bought for it is, I know.

Molly O’Shea3:44

Allright, we have a new entrant on the video. So we're here with Ezra. Ezra is also a co-founder. Do you want to give a couple sentences on your background and then we'll talk about the vibe table?

Ezra Feilden3:54

For sure. Yeah, my name is Ezra Feilden. I'm the co-founder and CTO at Starcloud. Before Starcloud, I was with Airbus designing and building satellites, focusing on large deployable structures, which is a very critical piece of what we're building here.

And then before I before that, I did my PhD in materials engineering.

Molly O’Shea4:15

Damn.

Ezra Feilden4:17

So yeah, we're standing in front of our vibe table, our very old, very beaten-up vibe table. We had to get this on an extremely short lead time, and new vibe tables are, you know, 26 months lead time, over a million dollars, and that didn't work for our schedule.

So the only option available to us and we had to do this test in-house for various reasons. So the only option available to us was to get a secondhand vibe table. And this one, I can tell you, has had a life.

It is as old as I am. It came to us filled with water.

Molly O’Shea4:52

No.

Ezra Feilden4:53

And with a horrendous internal leak. So there's very high voltage inside. There's obviously it's vibrating. There's high temperatures. Andright in the heart of all of that, there was a very large leak, which is the reason why the previous owner sold it, evidently.

So we didn't realize that until we got it in-house, you know, two days before the test, essentially.

Molly O’Shea5:16

Oh my God.

Ezra Feilden5:16

And so through the weekend, like, evenings and weekends, we had to absolutely hustle to tear this thing downright to the core, repair the leak. We had an expert who from basically, like, the country's expert in vibe tables come and tell us that the repair is not possible.

And we pressed on and we got it limping along, at least enough to complete our spacecraft-level vibe test.

Molly O’Shea5:44

So do you find this on, like, Facebook Marketplace? Like, where do we find old vibe tables?

Ezra Feilden5:50

Yeah, so it tends to be auction houses. Yeah, surplus auction houses. When companies go out of business, they get rid of all their assets. And yeah, that's a bit of a yeah, there's some diamonds in the rough there, for sure.

Philip Johnston6:04

It's not easy to move. There's about 60 tons.

Molly O’Shea6:07

Oh my God.

Ezra Feilden6:08

16 tons.

Philip Johnston6:08

Sorry, 16. Sorry, sorry. 16 tons. Yeah, yeah. Which is

a bit of a beast.

Ezra Feilden6:15

Yeah, it's hefty. And, you know, to run, just to power this thing, we need a generator. So we have a very large generator outside.

Molly O’Shea6:23

I know when I was pulling up, I was like, oh, we're in kind of like a warehouse office park. Which one could possibly be Starcloud? Probably the one with huge generators outside.

Ezra Feilden6:33

Yeah, that's yeah. But yeah, I mean, this is when you have extremely tight timelines, when you're trying to do new things very quickly, you often find yourself in these kind of situations where you have to get very creative and hustle and basically not take no for an answer and just be incredibly scrappy.

And that's, you know, our superpower as a startup, I think, is the ability to turn these crazy scenarios around and make a success of them.

Molly O’Shea7:01

It's a great point, because Starcloud, you guys went from founding to in orbit in 21 months.

Seattle roots7:01

Philip Johnston7:06

Yeah, which is a record. I think the fastest anybody did that before us was four years. And that was basically because Adi and Ezra built the satellite by hand. Yeah, we'll speak with Adi in a minute, but.

Molly O’Shea7:17

Oh my God. And so I know this is something that might surprise people. It definitely surprised me, because now I'm doing more of these tours, and the locations, like, it's not El Segundo, it's not down in Long Beach, but you guys are up here in the Seattle region.

So why Seattle?

Philip Johnston7:38

Yeah, so people don't realize this, but 90% of all satellites launched in the last few years by mass were designed, built, and tested in Redmond, Washington, which is exactly where we are now. So it's if you run we were literally me and Ezra were sitting in El Segundo for the first month of the company, and we were typing into LinkedIn like, okay, spacecraft demo engineer, and it was literally going like Redmond, Redmond, Redmond, Bellevue, Seattle, Redmond, Redmond, and we were like, okay, shit, I guess we have to move up.

And yeah, so about half our team actually formerly worked at SpaceX. The other half were the hyperscalers, so we have AWS and Azure down the road. So for doing data centers in space, this is literally the best place in the world you could be.

Molly O’Shea8:18

Okay, so we're also joined by another co-founder of Starcloud, Adi. So Adi, tell us a little bit about your background and how did you end up here?

Adi Oltean8:26

Yeah. Before Starcloud, I was at SpaceX for about two years. I was a responsible engineer for a feature called Tracking Beams, which essentially gives starling to all the in-motion vehicles, including aviation, cruise ships, and even the Starship. So if you've ever seen those cool Starship videos.

Molly O’Shea8:44

Yeah.

Adi Oltean8:45

I have built that. Before Star before SpaceX, I was at Microsoft for about two decades. And in the last couple of years or so, I was working on the GPU, large-scale GPU deployments in production. We onboarded the very first large language models before they were called LLMs in a bunch of data centers and working very closely with Nvidia on that.

And it was, like, really rewarding. And to be part of two keynotes in GDC 1 in 2019 where Jensen talked about conversational AI, that was what it was called back then, and our demo was part of that keynote.

And then later this year, part of the same GDC keynote in San Jose, Jensen introduced Space One, which is one the very first GPU designed to work in space.

Molly O’Shea9:40

Damn. Yeah, Philip was telling me you've been mentioned in GTC talks multiple times.

Adi Oltean9:45

Not me personally, but our team, yes.

Molly O’Shea9:48

That's incredible.

Adi Oltean9:48

I helped build the demo.

Molly O’Shea9:50

Yeah. So we're standing in front of Starcloud 2. Do you want to give us a little rundown on it?

Adi Oltean9:54

Yeah. So people are busy at the moment. They're about to fire the HDRM, which is essentially a latch that will deploy the solar panels on each side of the spacecraft. And if you hear a loud pop, that's it.

So we are testing the satellites actively. We are testing various systems.

Philip Johnston10:16

There you go.

Adi Oltean10:18

No, it was finished.

Molly O’Shea10:19

I was like, okay.

Adi Oltean10:20

I was like, something's going to explode in here. Maybe not as climactic as wanted, but this is actually the most important deployment event that happens in orbit. We use that to kick off the deployment of both solar panels in orbit and make sure we can get kilowatts of power to all our compute.

Molly O’Shea10:43

So I know this is a very new facility, but where does that get made? Like, where are all these components coming from? Is it vertically integrated? How do you think about engineering?

Adi Oltean10:55

We try to vertically integrate as much as possible. Obviously, we are not manufacturing the Nvidia boards or other high-level compute systems, but we integrate everything here, and we manufactured our radiators. We put together the solar panels. So a lot of the cooling system is being built internally here, so which is kind of our secret sauce, if you will.

Another HDRM firing. And yeah, we try to integrate as much as possible in-house.

Cooling system11:27

Molly O’Shea11:27

What's been the biggest technical challenge coming over to Starcloud?

Adi Oltean11:33

I think the cooling system and the radiators are the by far the largest technical challenge. And I think we are very proud of what we did and how it works and how compact the whole thing is. It's mostly focused on engineering costs rather than is this possible or not.

We know it's possible, but the question is how do you make it super cheap and how do you make it manufacturable at scale?

Molly O’Shea11:56

Yeah, I mean, that's a big point. I was interviewing Sean Maguire, and he was talking about data centers in space, and he was like, I did the math on it, and it makes sense. The math matters. And so a large component of that is energy transfer and, like, how much energy is used on Earth for Earth data centers versus in space.

And so in space, this is going to be a little bit of a different environment. It is very, very cold, but you still need radiators, you need cooling, all that kind of stuff. So could you explain that out a little bit more?

Adi Oltean12:25

Well, it's basically the engineering math is hard, but economic math is the one that truly matters in orbit. So you what you want is to dissipate every single watt you're receiving from the sun. So that is the hard part.

How do you make it very efficiently? How do you essentially emulate a cooling system that mimics the one in data centers today on Earth? As probably people know, 2025 was the year of liquid cooling in all the data centers.

So people have to switch to liquid cooling because that's the only way to achieve the incredible densities of compute in the next generation of data centers. And we are catalyzing on that and using the same thing, the same technology in space as well.

Molly O’Shea13:13

For those who don't know about the Fermi Explorer mission, can you explain that and why it's significant for you?

Alpha Centauri13:13

Philip Johnston13:18

Yeah. So my co-founders, Adi, Ezra, and I have created a nonprofit with a few others, Cam Gaffar and others. We created a nonprofit to send the first spacecraft to the nearest star. So the nearest star system to us is Alpha Centauri.

It's about four light-years away. And we realized after doing Starcloud 1 that you can do things very cheaply. Like, for example, Starcloud 1, we had a quote from one of the primes. They told us it would cost $75 million to $100 million to do Starcloud 1.

And we did it for about $2.5 million.

Molly O’Shea13:47

No way.

Philip Johnston13:48

Yeah. So we realized you can do things very cheaply, and we found.

Molly O’Shea13:50

You just put things in space.

Philip Johnston13:52

Yeah, pretty much. And we found a trajectory. We had a physical AI lab out of MIT run this analysis and find a trajectory that allows us to get a spacecraft on a trajectory to Alpha Centauri for about $10 to $15 million.

So it's going to it won't use any technology that doesn't exist today. It's going to use solar Hall effect ion thrusters with solar to power it. And we're going to basically be spiraling towards the sun for five years, and then we're going to fire the thruster at the perihelion, at the closest point to the sun, for another five years to create these ever-expanding ellipses.

And then on the last firing, we're just going to fling off in the direction it's actually not even anywhere close to where Alpha Centauri is today. Alpha Centauri is moving towards us, and it will intersect on a path in about 80,000 years.

So the hope is that we'll be both the first to leave on this journey to another star and also the last to arrive. So, you know, hopefully in 50 years or 100 years, there'll be better propulsion technology. In 1,000 years, there'll be much better propulsion technology.

So I hope stuff starts flying past us.

Molly O’Shea14:57

Yeah.

Philip Johnston14:57

And then by the time we arrive in 80,000 years, you know, maybe for 15,000 years, there's already been a colony, even if your propulsion technology was only 20% faster. And so what I hope happens is they sort of applaud our spacecraft across the finish line, they capture it, and they put it in a museum or something.

And then from there, it'll take sort of 5 to 10 million years to settle the galaxy, even with just today's technology. And then from there, it's about a billion years to get to Andromeda, our nearest galaxy. And then from there, to get to the local group of 50 galaxies is about another sort of 5 billion years.

And the purpose for me of doing it is, like, either all of that happens or it doesn't for some reason. And, like, yeah, there's this idea of the Fermi paradox, the idea that the question of why we don't see more intelligence in our galaxy or more obvious evidence of it.

Molly O’Shea15:45

You mean aliens.

Philip Johnston15:46

Yeah, or why our solar system isn't part of a galactic empire, you know?

Molly O’Shea15:50

Yeah.

Philip Johnston15:50

If they it's pretty quick. Like, 10 million years to settle the galaxy is the blink of an eye in galactic time frames. So if there had been intelligent life on any other star, trillion planets in our galaxy, if there had been intelligent life on any other one in the last 10 billion years, galaxies have been around for more than 10 billion years, then it would have been 5 million years to settle the whole galaxy.

And so it's really kind of concerning that we don't see more evidence of that. To me, there's two options. Either we're exceptionally rare, maybe we're the first species or intelligence to get to this level of complexity in the whole galaxy, or maybe even in the local 50 cluster of galaxies, or and by the way, I'm open to that.

I like that idea. Like, maybe we're going to be the first to settle the galaxy, and that's a great privilege. Or the other alternative is intelligent life doesn't last very long. Maybe there's been intelligent life on many other stars in our galaxy.

Molly O’Shea16:40

Damn.

Philip Johnston16:41

And for some reason, it doesn't survive very long. So either way, I think we should, like, know about that. And one of the reasons to do this mission is to make people think more about our place in the galaxy and more about the Fermi paradox and other things.

Molly O’Shea16:53

How did you get into space, and how did you get interested in this?

Philip Johnston16:56

So, I mean, I've always been interested in space. Like, I wanted to be an astronaut as a kid, like anybody.

Molly O’Shea17:00

But why? Like, what exposed you to that? You just.

Philip Johnston17:04

I guess, like, yeah, sci-fi movies when I was a kid. Like, I read the Asimov novels foundation series. Yeah, it was there was this there's this phrase that people sometimes say, which is, like, we're too late to explore the Earth, and we're too early to explore the solar system and the galaxy.

And I always thought that was really sad. Like, it was exciting to me to be an explorer, and the, you know, the voyages across the globe were kind of exciting to me. And then realizing, okay, we've kind of explored everything now.

Everything's done. It was kind of sad. And then, yeah, recently started thinking, okay, well, maybe we can do our own, like, our own effort. Maybe we can be the first to send a spacecraft to the nearest star. And we're like, what an incredible privilege that would be.

Molly O’Shea17:50

So if you wrote a sentimental note on Starcloud 1, what are you going to put on the spacecraft?

Philip Johnston17:56

I'm definitely going to put the name of my fiancée on there.

So for the low, low price of.

Molly O’Shea18:05

No, well, oh, you're going to start selling logo spots?

Philip Johnston18:07

Yeah, yeah, yeah.

Molly O’Shea18:07

Wow. We got an advertising option.

Philip Johnston18:09

Yeah, there you go. People can go to fermi-explorer.com/donate, and people can put whatever message they want on there. But what would I put on there? Like, I'm excited to put, like, lots of information, like records of records of what Earth is like.

And we're going to have some interest we'll have some scientific payloads on there. We'll have the Golden Record, which is one of the artworks that they put on one of the probes going out of the solar system. But then we'll also have a solicitation period for various artistic payloads, like various artworks that people can put on there.

So we're actually yeah, we're drawing ideas from various places. One of them one cool-ish scientific payload. Did you ever see this fruit fly that Google or there was a startup, they cut they sliced the brain of a fruit fly?

Molly O’Shea18:57

That's crazy. Yeah.

Philip Johnston18:57

Yeah. So we'll put a digital copy of that, like, this fruit fly thing, and, like.

Molly O’Shea19:02

Whoever finds this is going to be like, humans are tiny.

Philip Johnston19:05

Yeah, yeah, yeah.

Molly O’Shea19:06

This.

Philip Johnston19:06

They were like, how the hell did they build this? Yeah, yeah, yeah.

Hot takes19:10

Molly O’Shea19:10

That's awesome. Allright. So I do have to address this because every time we've done plenty of hot takes now. We did one at the New York Stock Exchange. We did one in Paris at the Raise AI Summit. So I have to ask you now, what is your hottest take?

Philip Johnston19:27

Every time I do a hot take with you, I get in trouble. Because usually, last time we did it, I said, you should buy SpaceX stock. And then Elon retweeted it. And then.

Molly O’Shea19:36

But you wereright.

Philip Johnston19:36

I was totallyright. I was 100%right.

Molly O’Shea19:39

Okay.

Philip Johnston19:41

And then what was my hottest take? Let's stick on the theme. So Elon reposted that they're going to be worth $100 trillion in 10 years. I think they might be worth more than $100 trillion in 10 years.

Molly O’Shea19:54

You do?

Philip Johnston19:55

Yes.

Molly O’Shea19:55

If all goes to plan and there's no world war, you believe.

Philip Johnston19:59

That's my hottest take.

Molly O’Shea19:59

SpaceX will be worth more than $100 trillion?

Philip Johnston20:01

Correct.

Molly O’Shea20:03

Okay. Well, that'll be good for business.

Philip Johnston20:06

Yeah, exactly.

Molly O’Shea20:08

What would make that up, though? So, like, break that down. How do you think about it?

Philip Johnston20:13

Actually, well, mostly a good chunk of it will come from the fact that Tesla's Optimus will be up and running. And so once you have Optimus is building Optimus factories, then you have this incredible exponential. And so for all of manufacturing, all of yeah, the rate of the rate of growth will increase a lot once Optimus is producing Optimuses.

It's a bit like what's happening now with the recursive self-improvement, but for the physical world.

Molly O’Shea20:42

Do you think Tesla will merge with SpaceX, which will help with that?

Philip Johnston20:46

This isn't a hot take. This is just a fact.

Molly O’Shea20:48

Okay.

Philip Johnston20:49

SpaceX is going to buy Tesla, and they have to wait until the unlocks of the stock because if they do, then everyone's going to say the price wasn't fair. So at the moment, yeah, at the moment, it's you're not going to see too many announcements.

But I think there's a roadster announcement tonight. But beyond that, I don't think you're going to see any announcements about Optimus for the next year. And then once they once they do the merger, then we'll hear a lot more.

Molly O’Shea21:15

I know this will come out after the roadster announcement, but what's your prediction?

Philip Johnston21:21

What I've heard is they have these cold gas thrusters from star from, like, the spacecraft that they've so you have a compressor that's compressing air, essentially, and then that's being fired out the back, which means which gives you, like, absurd acceleration and cornering and everything else.

And also, I think I think there's I think.

Molly O’Shea21:42

Lift?

Philip Johnston21:43

Lift. Yeah. I actually think you can get lift on these things.

Molly O’Shea21:46

Oh, my gosh.

Philip Johnston21:47

What do you what do you think?

Molly O’Shea21:48

I just I kind of thought it might be an EV toll.

Philip Johnston21:53

That would be wild, but I don't think it is.

Molly O’Shea21:55

You don't think it is?

Philip Johnston21:56

We would know by now if it's an EV toll.

Molly O’Shea21:58

I think you could just skip the whole car thing and just go to EV toll, call it a roadster.

Philip Johnston22:04

That would be amazing. Like, that would be incredible. But I would be extremely surprised if it's an EV toll.

Molly O’Shea22:09

Allright. Stay tuned for our predictions. Oh, my God. I don't know if this one this one is a little bit more than length.

Philip Johnston22:18

Length and girth. Length and girth.

Molly O’Shea22:22

That's crazy. So what do you.

Philip Johnston22:23

Yeah, so.

Molly O’Shea22:24

Use this for what? What do you use it for?

Philip Johnston22:26

This is this is for screwing in bolts at the warehouse.

Molly O’Shea22:30

That's crazy. Where did you find this?

Philip Johnston22:32

I went to a Halloween store this morning because I was like.

Molly O’Shea22:34

Oh, okay. Well, that's actually pretty impressive for a Halloween store.

Philip Johnston22:36

I can't be sword mugged by the rest of your guests.

Molly O’Shea22:38

Yeah. That's wild.

We'll go to the fab shop so we can see where we're welding and fabricating various aluminum and steel parts, some of which for the actual spacecraft and most of which is for test equipment and other things. Maybe Ezra can talk a bit about the fab shop.

Adi Oltean24:50

Yeah, this is a this is a big upgrade from our last facility. So we've literally just moved in here as of, like, the last few days. So everything's a little bit chaotic.

Molly O’Shea25:01

Wow.

Adi Oltean25:01

But we moved from this tiny office building into into this lovely manufacturing space. And this area of it is we call the fab shop. So this is where we do dirtier work so that the cleaner work goes on in there.

Dirtier work happens here. So we're talking sheet metal work, welding, and, yeah, general fabrication. So we have lots of fab shop equipment here. We have MIG welding, TIG welding, laser welding. We have a shear for sheet metal. Andright here, we have the manufacturing demonstrator for Starcloud 3.

So Starcloud 3 is our largest platform. It's a 2-ton vehicle, approximately. Yeah, so this is the Starcloud 3 manufacturing demonstrator. So we wanted to get some experience building a primary structure of the scale of our Starcloud 3 vehicle.

So this vehicle is designed to go through the PEZ dispenser door for Starship. It's around 2 tons, fully loaded, 235 kilowatts. And we can deploy up to 50 of them per Starship launch.

Molly O’Shea26:12

My God.

Adi Oltean26:13

And.

Molly O’Shea26:14

I've not seen Starship, or I have no idea on the scale of that. But you said two of these fit in?

Adi Oltean26:22

So per layer, so you get two of these.

Molly O’Shea26:25

Wide and then.

Adi Oltean26:26

Wide and then 25 tall.

Molly O’Shea26:28

Oh, my God.

Adi Oltean26:28

So it's, yeah, from here to the ceilings of these stacked in two layers.

Molly O’Shea26:31

Soright now, we're in the middle of Starship. We're inside of it.

Adi Oltean26:34

Yeah.

Molly O’Shea26:35

Okay.

Adi Oltean26:35

Yeah, that gives you an idea of the diameter of Starship, the fact that this can fit in there.

Molly O’Shea26:39

That's insane.

Adi Oltean26:40

It's an enormous vehicle.

Molly O’Shea26:41

Where how have you guys been launching today? What are I know you have three launches coming up as well.

Adi Oltean26:46

So our first launch was with Falcon 9. So, yeah, Falcon 9 rideshare mission. Our upcoming launches are all with Falcon. And, yeah, it's really it's really hard to beat the the the benefits and the economics of rideshare when you're when you're producing single missions like we are at the moment.

The future is definitely Starship, and that's what we're gearing up for here.

Molly O’Shea27:13

What's the process like for booking a ride?

Adi Oltean27:17

For so booking rideshare is unbelievably easy. So it was actually the basically, the first thing we did as a company was we booked the launch for Starcloud 1.

Molly O’Shea27:25

Do you have to book it really far in advance? Like, how do you how do you I mean, you're, like, gunning for getting on the vehicle, but, like, how does that work?

Adi Oltean27:32

Yeah. So we we booked about, yeah, 21 months in advance. And the process is the initial booking is you can pay for it with a credit card. You can get a confirmation straight away.

Philip Johnston27:46

You could.

Adi Oltean27:47

You could.

Molly O’Shea27:47

You could.

Adi Oltean27:48

Yeah. Rideshare is Falcon 9 rideshare is going away, though. So these were the rosy days when it was much easier to get a single payload launched. So we're in a transitionary period at the moment where Falcon 9 is being wound down and, yeah, Starship has yet to be wound up.

So we're definitely in a crunch time at the moment when it comes to launch.

Molly O’Shea28:11

What is the process for that, though? Do you need insurance? What happens if it doesn't go to plan?

Adi Oltean28:18

So it's insurance is relatively inexpensive for Falcon 9 because it has such a strong track record, you know, 300 launches, consecutive launches without a failure. But so you can insure the a failure on launch, you know, the rocket explodes, the payload doesn't separate, that kind of thing.

It's much more difficult to ensure things going wrong with the spacecraft as it's, you know, this is the first first spacecraft of its type to be built. So we got insurance for the for the launch. And, you know, that can if something goes wrong, then that can give you a bit of a financial payout.

But what we what it can't compensate you for is the lost time, which is really the most valuable resource for, like, a fast-moving startup. So, yeah, I'm slightly on the fence of the value of insuring payloads. But, yeah, we take it case by case.

Molly O’Shea29:13

We were just at Rocket Lab, and we did a tour. We did a series there. And the one topic that keeps on getting delayed is Neutron. How do you think that will or will not affect the market if and when it starts to be serviceable?

Adi Oltean29:34

Yeah, it's yeah, they I think yes, just yesterday, they publicly announced the first flight will be 2027. You know, composite manufacturing is really hard. I know from, yeah, personal experience, very large composite structures often take a bit longer than you expect, especially when you're producing them for the first time and you're running the tooling for the first time.

I have I have a lot of faith that Rocket Lab can can get Neutron flying regularly. They've proven that they 100 launches of Electron, so they can they can do scale. So, yeah, we're definitely rooting for them as well.

Molly O’Shea30:11

Allright, so now we're walking around here. You have a motorcycle. We're going to go look at that.

Philip Johnston30:16

We can look at it if you want.

Molly O’Shea30:17

What whose is that?

Philip Johnston30:18

I think.

Molly O’Shea30:18

What was the joke, by the way?

Philip Johnston30:19

I think it's Bailey's.

Molly O’Shea30:22

Does that go into space?

Philip Johnston30:23

Yeah, maybe. It depends how fast they go. I'm, like.

Molly O’Shea30:27

Everyone's laughing.

Philip Johnston30:27

I'm permanently terrified that somebody's going to kill themselves on a motorbike. Like, half our team is.

Molly O’Shea30:31

Oh, no. Yeah, that is a liability.

Philip Johnston30:32

Yeah, yeah. So this is kind of interesting. This is a it's a half-built, zero-gravity sort of offloading rig. And so we have these runners that run in two axes. And so the deployable Starcloud 2 goes runs down this.

This is one half of it. So, yeah, the other half would.

Molly O’Shea30:52

Oh, wow.

Philip Johnston30:53

The other half goes that side. So it's, like, 120-foot-long deployable.

Molly O’Shea30:56

Oh, my God.

Philip Johnston30:58

Yeah. So that small package you saw there extends down the length of this.

Molly O’Shea31:04

What?

Philip Johnston31:04

And then on one side and then down the length of that on the other side.

Molly O’Shea31:07

Oh, my God.

Philip Johnston31:08

Yeah, yeah.

Molly O’Shea31:09

What? Okay.

Philip Johnston31:10

And the first the first few segments of that is a radiator segment. That's the radiator we've designed and fabricated in-house. As Adi was mentioning, it's our design is way more efficient than any other. So when we launch in January, it'll be about it'll be by far the largest commercial deployable radiator in space.

And the nearest comparison is the International Space Station. Our radiator is at least 10 times less mass per watt of dissipation than the ISS radiator and about 500 times less cost per watt of dissipation than the ISS radiator.

Now, the ISS is an easy benchmark to me on cost, but on mass, it's quite an achievement. Like, yeah.

Molly O’Shea31:45

One of the big biggest topics, and I know we talked about this with Adi, is the economics of this.

Philip Johnston31:52

Yeah.

Molly O’Shea31:52

You are making more economical satellites going out in space and the vehicle itself. So that's one thing. And so I'd love to break that down in the economics there and then also further drill down the difference between on-land, like, terrestrial data centers versus orbital.

Economics & chips31:52

Philip Johnston32:11

Yeah. So the whole thing is actually contingent on the launch cost. So if the launch cost gets below around $500 a kilo, then it will be much cheaper to do this in space than terrestrially. And I think a sort of good comparison for this is if you build a new solar project on Earth to power a data center, because solar is kind of the cheapest form of energy we have terrestrially.

And so the way you can think about it is solar terrestrially has these three big costs. The biggest cost is the cost of per-meter land, depending where you are. Second biggest cost is the cost of battery storage and backup power.

And then the last cost is the cost of the solar cells themselves. And so in space, number one, we don't need per-meter land, so your biggest cost is gone. We don't need batteries and backup power because they're 24/7 in the sun.

And then we need eight times less solar cells because one square meter of solar panel in space produces about eight times the energy of one in space. So we have all these savings in space. The main additional cost we have is the launch cost.

And so that's where this trade-off comes. And that's where we see when you run those numbers, you come out to about $500 a kilo, where it makes more sense to do it in space than terrestrially. And, of course,right now with Starship, we're at about $5,000 a kilo sorry, with Falcon 9.

The design of Starship is designed to produce launch costs of internal launch costs for SpaceX of sort of $20 to $40 a kilo. So so long as they pass that launch cost through to us at anything less than, say, 10 times their marginal launch cost or even more, whether that makes sense for us.

Right now, by the way, on Falcon 9, they charge two or three times their marginal launch cost. So it seems reasonable.

Molly O’Shea33:48

Yeah.

Philip Johnston33:48

Yeah.

Molly O’Shea33:50

Another thing that I listened to so I listened to a handful of your interviews. One of the other very concerning points is chips and chip failures. So how does that work into the model?

Philip Johnston34:01

Yeah, for sure. It's actually a super, like, relevant point. I think it's actually more relevant and pertinent than even cooling, which is people think is the biggest challenge. We've basically solved the cooling challenge. The other part of it that we're working on is the radiation shielding and testing all the chips in different particle accelerators to make sure they can survive the radiation environment in space.

And the reason we put so much time into that is if the chips have, you know, like, a 10 or 20 percent higher failure rate in space than they do on the ground, then the whole economics of the model fall apart.

And the reason is the chips are by far the most expensive part of what we're doing, actually. And so there's a few ways that you can go around that. I mean, essentially, we're not going to have access to the satellites once they've launched.

So they operate a bit like the way the Starlink satellites work, which is you need to have redundancy on critical systems, you know, things like pumps. And then you over-provision things which fail over time. Like, the solar panels, you're going to lose a few percent per year, so you slightly over-provision that.

And then on the chips, we have a longer burn-in period on the ground. Most chips actually fail in the first period of their life. And so if you can put them through a more rigorous burn-in period.

Molly O’Shea35:10

Why is that?

Philip Johnston35:11

I don't know. It's basically the they call it infant mortality of the chips.

Molly O’Shea35:15

Oh, no.

Philip Johnston35:16

Yeah. I know. It sounds kind of terrible.

Molly O’Shea35:19

That's horrible.

Philip Johnston35:19

Yeah, yeah. So what you want is to get through the infancy period and find out all those failures. So for Starcloud 2, we had a three-month burn-in period. It basically means you run the chips hot for three months so you can find all those failures early.

It's basically like, yeah, if you can survive if the chips can survive three months at full power, the chance they have a failure from that point onwards diminishes very dramatically versus the chance they have a failure in the first three months.

Molly O’Shea35:47

So you have five chips up in spaceright now, including one H100?

Philip Johnston35:51

Yes.

Molly O’Shea35:52

What are they doing?

Philip Johnston35:54

So actually, we have yeah, so we have three chips from Nvidia, two from ARM, and we also have some CPUs from AMD on Starcloud 1. And what they're doing is, at the moment, we use them to do some interesting workloads, like train the first model in space, nanoGPT from Andrej Karpathy.

We did the first run the first version of Gemini. But now they're actually doing useful workloads for government customers. So they are mainly in sort of as a test phase, but we're doing inference on satellite imagery, so on synthetic aperture radar data, on hyperspectral data.

So we actually just we'll do an announcement about some of the results of this, but we've got some very interesting results. And the use case for that is, let's say the government has a bunch of military satellites. They collect enormous amounts of mostly imagery, but also other types of data.

They don't want to have to wait for a ground station to downlink all of that data. So if they can run inference on that at the edge, we can then send down the insight much quicker. And so, for example, if they're monitoring a patch of water, they might want to know, is there a vessel crossing some boundary?

At the moment, what they do is they take an enormous amount of imagery, and then they have to wait at least an hour and a half to get to a ground station. And then they try and downlink as much as they can, but that's usually not very much.

Once we're in space, we have a bunch of optical terminals on our satellite. In real time, they can send data to us. We can then run the inference workloads on our satellite, and then we can downlink the coordinates of a vessel, for example, in minutes rather than hours and days, which is the current way that this works.

Molly O’Shea37:27

That's wild.

Philip Johnston37:28

Yeah.

Molly O’Shea37:29

Oh, my gosh. So are initial use cases for these satellites and what they're doingright now, the satellite operators and that kind of data, when do you think it'll reach outward into other parts of the economy?

Philip Johnston37:41

Yeah. So it's entirely dependent on the launch cost hitting $500 a kilo. So the business, as it is today, runs really, you know, economically with the current launch price. In order to be competitive with terrestrial data centers on energy and infrastructure cost, that's where we need the launch cost to be $500 a kilo or less.

My expectation is that sort of we've already seen Starship deploying its first payloads. We'll see reusability of Starship probably within a year, or at least we'll see the capture of the upper stage. Reflight might take a little bit longer.

And then 2028 onwards, we're hoping to see SpaceX selling capacity to commercial customers. You know, if they don't, we also are, you know, considering other options. And so we've booked on a bunch of different other launch vehicles, not just Falcon 9, but also some others.

And we'll I think we announced Stoke already. We announced Firefly. We'll announce some others soon.

Molly O’Shea38:39

Congrats.

Philip Johnston38:39

Yeah.

Molly O’Shea38:40

Well, if the goal on Earth is to get to a 1-gigawatt facility, a 5-gigawatt facility, what is realistic for space, and what does that look like in mass?

Philip Johnston38:51

Yeah. So very large data centers on Earth are usually used for training large models. So you need a very highly internally networked cluster to train a frontier model. It's in space, for a long time, we're probably not going to be docking together things.

And so most of the workloads we're going to be doing in space is running inference. And that's usually for things like coding agents and back-office business processing agents and ChatGPT queries. So the roadmap is we launch a bunch of things like this.

So the 200-kilowatt one, we can launch 50 per Starship. So you're talking about close to 10 kilowatts sorry, 10 megawatts of new compute capacity per Starship launch. And we've filed with the FCC for a constellation of 88,000 of those.

Molly O’Shea39:37

That's crazy.

Philip Johnston39:37

Yeah. So and that's just the first 88,000. So that will.

Molly O’Shea39:41

Just the first 88,000?

Philip Johnston39:43

Yeah, yeah. I mean, we're not stopping there. So that enables us to deploy the first 20 gigawatts. We think we can fit about 10 terawatts in this dawn-dusk-sunsynchronous orbit. So that's about 20 times the entire US power grid.

And then once we run out of that, we can go to cislunar, MEO, Beyond Geo, and to the Lagrange points. And we can yeah, essentially, if you want to scale much more compute, then you really need to do it in space.

Molly O’Shea40:08

So will we have access to sunlight on Earth if we have so many solar panels up?

Philip Johnston40:14

Yes.

Molly O’Shea40:15

We will.

Philip Johnston40:16

And the reason is.

Molly O’Shea40:17

Because I saw was it Starcloud 3? It's four square kilometers in orbit on his.

Philip Johnston40:24

Yes. Yeah, Starcloud 3 will take a while before we can start docking together these large structures. But even when we do, they won't ever cast a shadow on the Earth. And the reason is they're flying over the poles.

So if this is the sun is here and this is Earth, Earth spinning on its axis, they fly over the poles like this. And so the yeah, the Earth will never create a shadow on our satellite, and our satellite will never create a shadow on Earth.

So they never go behind or in front of Earth, basically.

Molly O’Shea40:54

The more you know.

Philip Johnston40:55

The more you know.

Molly O’Shea40:56

Science. So, Philip, we're back at the vibe table, and we're about to do some testing.

Vibe test demo41:01

Philip Johnston41:01

Yeah.

Molly O’Shea41:02

Do you want to explain this?

Philip Johnston41:03

Yeah. So we need to simulate the launch environment. And so in order for SpaceX to allow us to launch on a rocket with multiple tenants, they want to make sure that both nothing's going to fly off from any individual satellite in launch.

But also, they don't want any satellite to resonate at a certain frequency, which throws the whole stack off. And so the point of the vibe table is to put the satellite through every different frequency and amplitude that the satellite is going to experience during launch and also this shock test so that we make sure nothing flies off.

And we also make sure that we don't have resonance at a certain frequency.

Molly O’Shea41:38

How long do you run it for?

Philip Johnston41:40

It depends on the test, but the launch environment itself is about seven minutes. And so there are some tests we would run for a few minutes. Most tests we run for a shorter period, especially what they call the sort of

yeah, like, random vibe, we run a bit longer, but the shock test we run for shorter.

Molly O’Shea41:59

Have you ever.

Philip Johnston42:00

Sat on a vibe table.

Molly O’Shea42:01

Sat on that?

Philip Johnston42:03

I have never sat on that, I have to say. Yeah. People.

Molly O’Shea42:07

I've had that. I've touched them before, but.

Philip Johnston42:11

Oh, yeah.

Molly O’Shea42:13

We were at Zipline, and we went into their testing room, and they had a vibe table and these, like, RC propeller like RC fans.

Philip Johnston42:24

Oh, yeah.

Molly O’Shea42:24

To test the drones with. And they would fly them in front of it and see if anything would, you know.

Philip Johnston42:29

Oh, really?

Molly O’Shea42:30

Get fragile or break, if there were any, like, fractures. And it ended up just being me walking through RC fans.

Philip Johnston42:38

No way.

Molly O’Shea42:38

Which is they're I think they go, like, 80 miles an hour.

Philip Johnston42:41

Wow.

Molly O’Shea42:41

Yeah.

Philip Johnston42:42

Crazy. Oh, there you go.

Molly O’Shea42:45

Oh.

Philip Johnston42:46

So this is a very low-frequency test. We're doing it as low-frequency, mainly so that you can see what it looks like when it moves. But the when it moves faster, basically, you won't be able to see it moving.

That's if they're moving at least 50 Hertz, so 50 times back and forth per second. And this is basically a huge solenoid, so a huge magnet that's pulling this thing in and out. It's basically speeding up now. Yeah.

Molly O’Shea43:15

So we walk in?

Philip Johnston43:18

Yeah, yeah. We're good.

So the hardware we have on the table at the moment is part of our thermal management system called the accumulator. So as the so we have liquid cooling on Starcloud 2 and all of our future vehicles. As the liquid heats up, it wants to expand.

And so you have to have a component which allows that expansion to take place. Otherwise, you'll burst your cooling system. So that's what the accumulator does. It allows for that thermal expansion of the fluid to manage the pressure inside the cooling system.

And that's what we have on the tableright now is the accumulator for Starcloud 2. Yep.

We're good. Yeah, go for it.

Philip Johnston44:04

Yeah, yeah. There you go.

So.

Molly O’Shea44:14

Oh, my god.

Philip Johnston44:15

That's crazy. Yeah. So this isright now, the test is doing is what's called a sine sweep. It's where we're going to go through every different frequency and amplitude that the satellite will experience during launch. So it starts very low frequency.

We're doing this low frequency. Normally, we wouldn't even start this low, but we wanted to be able to see that it's moving here. As it gets faster and faster, you won't really be able to see the movement of it.

Molly O’Shea44:44

What is the worst thing that a vibe table has done?

Philip Johnston44:50

The worst thing that a vibe table what?

Molly O’Shea44:51

Has a vibe table, like, ever, like, as a magnet, like, shot out or anything?

Philip Johnston44:57

No. The actual vibe tables themselves are pretty safe. The worst thing that can happen with a vibe table is whatever you're testing can explode. So, for example, underneath Starcloud 2, we have this xenon tank for the thrusters. And if the xenon tank explodes, it's about half the explosive power of a hand grenade.

So.

Molly O’Shea45:19

Great. That's awesome. That's really good to know.

Philip Johnston45:21

Yeah, yeah.

Molly O’Shea45:22

OK.

Philip Johnston45:22

That's why we're not doing that test today. So.

Molly O’Shea45:24

Yeah. So does everyone leave the building when you test that?

Philip Johnston45:27

Yeah. Literally, everybody leaves the building. So we had we put this entire satellite on this. By the way, you can see it's in two axes. So the solenoid actually can flip up, and we can test it like this so that we can test in different axes.

But yeah, when we fly that test up, we have to everybody has to leave the building.

Molly O’Shea45:45

I doubt the toy manufacturer that has storage across the street has any idea what's going on in here.

Philip Johnston45:52

They have no idea.

Molly O’Shea45:54

They have no idea.

Philip Johnston45:54

But they are far enough away that we know that they're good.

Molly O’Shea45:59

They're going to be OK.

Philip Johnston46:00

They're safe. Yeah.

Molly O’Shea46:01

Like, why is everyone running out?

Philip Johnston46:05

Yeah, yeah.

That's first mode. Oh, OK, OK. So what they're testing for is this first mode. It's the first frequency at which it's resonating. And when you can hear it making this clicking sound, that means we've hit the first mode of this thing here.

What SpaceX requires is that you don't have a first mode below a certain frequency. I think it's around 40 Hertz.

Molly O’Shea46:32

OK.

Philip Johnston46:33

So it cannot resonate at anything less than 40 times a second. And the reason for that is, let's say it would resonate at, like, twice a second, then the whole thing's going to go like this back and forth.

Molly O’Shea46:43

Yeah.

Philip Johnston46:43

And that will move all the other payloads in the stack.

Molly O’Shea46:46

That's a really good point. So what is the process to get your spacecraft or any kind of components up into space tested to make sure that it's, like, viable for Falcon 9 or Starship?

Philip Johnston46:58

Yeah. So as we mentioned, booking is just put your credit card down. But then that kicks off a whole long process where both regulatory we have to file with the FCC for the orbit and for the spectrum we're going to use.

And we have to have a deorbit procedure and all of these kinds of things. And then SpaceX has a whole laundry list of requirements, mainly, to be honest, to make sure that your spacecraft isn't going to destroy any other spacecraft on the stack.

So if you book a fully dedicated Falcon 9, the requirements are less stringent than if you're booking a rideshare because they need to make sure you're not going to move the whole stack or you're not going to have things flying off and killing other spacecraft.

Molly O’Shea47:35

Damn.

Philip Johnston47:36

Yeah.

Molly O’Shea47:37

So how do they actually verify your, like, your approvals or.

Philip Johnston47:42

So we have to do vibe, and then we send them the vibe reports.

Molly O’Shea47:45

OK.

Philip Johnston47:45

After we've done the vibe testing.

Molly O’Shea47:47

Has anybody ever

lied?

Philip Johnston47:51

I don't think so. It would be quite hard to lie. I mean, reproducing these vibe reports is would be quite a challenge.

Molly O’Shea47:58

I don't know why you would do that unless you're an op.

Philip Johnston48:01

Unless you're an op.

Molly O’Shea48:02

Unless you're an op.

Philip Johnston48:04

There you go.

Molly O’Shea48:05

Geez. I think we just uncovered something. OK, cool.

Molly O’Shea49:20

Allright. So we're walking on through to the laser lab.

Makers' corner49:20

Philip Johnston49:23

Yeah.

Molly O’Shea49:23

How many people work at Starcloud?

Philip Johnston49:25

Right now, it's 30 people at Starcloud.

Molly O’Shea49:27

Wow. That's it?

Philip Johnston49:28

That's it. Yeah, yeah.

Molly O’Shea49:29

Oh, my god.

Philip Johnston49:31

30. Only two non-engineers. And so we'll probably have 50 by the end of the year, maybe 100 by the end of next year. But we very deliberately oh, there's a commitment. We very deliberately keep the team extremely lean.

As I say, we have, like, the most kick-ass engineering team on planet Earth. This will become a full, like, laser lab. So we'll use this for cutting and welding of aluminum and things. We just want to show you the we have a little demo for you.

Molly O’Shea49:58

Make things go zap.

Philip Johnston50:00

Yeah, yeah.

Molly O’Shea50:02

Hi.

Philip Johnston50:02

This is Camilo. He's.

Molly O’Shea50:03

Do we want to give you a mic, and you can talk through it? Or do you want to talk?

Adi Oltean50:07

We can. I can just do the.

Philip Johnston50:09

Yeah, yeah. You can have a little watch.

Molly O’Shea50:11

Demo.

Adi Oltean50:13

So this is our CNC X2 laser cutter. We use this to do quick prototyping on different types of materials. It just gives us a lot of different flexibility of getting things done as fast as possible. Soright now, I just have a little demo with some 30-gal stainless.

Sorry for the compressor. A little loud. But you'll see just how fast and how quick like, how quick this can do very complex cuts, and it's extremely accurate. So I'll.

Molly O’Shea50:41

Nervous?

Adi Oltean50:41

Run a quick demo here.

Molly O’Shea50:43

I always get nervous when I run.

Philip Johnston50:44

If you want to get the camera in there, you can probably.

Molly O’Shea50:46

Here, you can go in there, bro.

Philip Johnston50:47

Yeah.

Adi Oltean50:48

Yeah, my hand is better, too.

Molly O’Shea50:50

Thanks.

Adi Oltean50:51

Allright. Ready to go?

Molly O’Shea50:53

Fire.

Miguel Rivera50:56

Yeah, I can't see this through the reflection.

Philip Johnston50:59

You'll see it here.

Molly O’Shea51:29

Oh, my god. It's so cute.

Philip Johnston51:33

It's a little present for you.

Molly O’Shea51:34

That's awesome.

Adi Oltean51:35

I got some here that I already.

Molly O’Shea51:36

Oh, my god.

Adi Oltean51:38

So stuff like this helps a lot to move quickly, and it gives a lot of flexibility. And this is just to start. We're going to get much larger professional machines.

Molly O’Shea51:46

Wow. Is this your favorite tool or.

Adi Oltean51:48

One of them.

Molly O’Shea51:49

One of them?

Adi Oltean51:51

The next one's going to be my favorite.

Molly O’Shea51:53

What is it?

Adi Oltean51:53

It's going to be an Omada fiber laser cutter. So that we can fit material that's up to, I believe, 5 by 10 feet. So it's a professional-grade laser cutter. So it's going to be significantly more capable than this one is.

Molly O’Shea52:07

Damn. That's fun.

Adi Oltean52:10

Yeah.

Molly O’Shea52:11

Thank you.

Adi Oltean52:11

Of course.

Philip Johnston52:12

And as I understand, you yourself.

Molly O’Shea52:15

Oh, really? OK. I got to keep it.

Philip Johnston52:17

I can take it if you want me to put it in my pocket.

Molly O’Shea52:19

Here. I'll give it to Brent.

Allright. So we walked through.

Philip Johnston52:27

Fab shop.

Molly O’Shea52:28

Fab shop, assembly area, laser.

Philip Johnston52:31

We've got we'll be assembling a clean room, which I don't think we showed you, but that's on the other side. But as I understand, you yourself are actually a proficient welder. Is that true?

Molly O’Shea52:42

I made a very bold claim, but I did learn how to weld in college. And.

Philip Johnston52:47

I think we should put this to the test.

Molly O’Shea52:49

I'm down to try.

Philip Johnston52:49

I think your viewers would find this very exciting.

Molly O’Shea52:53

I am down to try. I was called a prodigy. So we'll see if that's still the case.

Philip Johnston52:58

We'll find out. We'll find out. So we have some welding materials back here. Shall we get you an.

Molly O’Shea53:04

Sure. Do I have to, like, try change everything?

Philip Johnston53:06

You might change it. Yeah, yeah, yeah.

Molly O’Shea53:08

Then I'll change. Allright. We've now advanced. We're now with Miguel, the engineering operations lead here at Starcloud. What are you going to show us today, and what's your background?

Miguel Rivera53:15

Yeah. So we're going to do a little bit of welding, just traditional welding. We do a lot of laser welding here at Starcloud, but we can also fabricate pretty much anything out of steel, aluminum, titanium, stainless steel. So we're set up for doing MIG weldingright now.

So we're going to have you run some beads and make some sparks. And yeah, so before here, I was the welder for Helion Energy, where we built fusion generators. I ran their fabrication shop over there for over a year.

And before that, I've been working at a lot of different fab shops doing architectural, structural, you know, welding and fabrication. And before that, I spent a decade in the US Army.

Molly O’Shea53:54

Oh, my god.

Miguel Rivera53:54

And deployed overseas.

Molly O’Shea53:56

How did you get into welding?

Miguel Rivera53:58

I wanted to do something very different. I wanted to do something that was, you know, neutral, so in the sense that I was contributing to society in a different way. So I decided to get into fabrication and welding after listening to Mike Rowe, the guy from Dirty Jobs.

He said, you know, the United States really needs welders, and it needs people to build stuff with their hands. And I was like, well, I can build stuff with my hands. So that led me to this career path, which has been very rewarding.

Molly O’Shea54:22

It's very satisfying.

Miguel Rivera54:23

Yeah. It's a lot of fun.

Molly O’Shea54:24

It's cool and addicting.

Miguel Rivera54:25

Yeah, it's a lot of fun. A lot of fun.

Philip Johnston54:27

That sounds like you. You posted recently on X. Somebody was like, "America needs more welders." And you're, like, posting shit about how good you are at welding. So now we're going to find out. Now we're going to find out.

Molly O’Shea54:36

Now we're going to find out. I used to be very good. So for background, this is, like, not at all in this world, but I went to college for studio art. Like, I grew up as an artist. And I was also very entrepreneurial, so I ended up going that path.

But I went to college for art. And so the first year of studio art, you do every discipline, every practice. And one of them, we went and we did metal work, woodwork, glass blowing.

Philip Johnston55:05

Nice.

Molly O’Shea55:05

All of the fun flame stuff. Like, it was so fun.

Philip Johnston55:09

It's a lot of fun.

Molly O’Shea55:09

And then I'm like, well, making this for fun isn't really a job, you know? Like, it's like it's you might as well be doing that but at trade school. So it's like, I don't really understand that. But it was so much fun.

Philip Johnston55:21

Nice.

Molly O’Shea55:21

And I was called a prodigy.

Philip Johnston55:24

We will see. We're going to find out.

Molly O’Shea55:25

Yeah.

Miguel Rivera55:26

So what we're going to do is we're going to give you a little bit of PPE.

Molly O’Shea55:28

OK.

Miguel Rivera55:29

So the sparks can burn you. So just put this jacket on. And we're going to give you some tools.

Molly O’Shea55:34

Should I tie my hair back?

Miguel Rivera55:36

If you keep it on the jacket, it might be fun.

Molly O’Shea55:38

Oh, just keep it behind you.

Miguel Rivera55:38

As long as it's behind you, you're fine. And make sure that you button at least a couple of the buttons.

Molly O’Shea55:44

I'll button.

Miguel Rivera55:45

As long as you have all this on, closed-toe shoes, you'll be just fine. If you feel anything hot, just stop and step back, but you should be perfectly fine.

Molly O’Shea55:52

Yeah, I remember we weren't allowed to wear any polyester.

Miguel Rivera55:55

Mm-hmm. Yeah.

Perfect. And then you can do your sleeves as well.

Molly O’Shea56:07

You haven't done any of this? Why?

Philip Johnston56:11

There's you.

Miguel Rivera56:11

He's never here.

Molly O’Shea56:13

Oh, my god.

Philip Johnston56:13

Traveling the world.

Molly O’Shea56:14

That's true. He's always on stage somewhere. Why aren't you in the shop?

Miguel Rivera56:18

So we'll have you put this on first. So the way that the way you put it on goes over your head, and you click this. And then you can leave this up,right? Then when it's time to weld, you can put it down.

You can see through it just fine. And the second that you start welding, it'll auto-darken.

Molly O’Shea56:31

OK.

Miguel Rivera56:31

So you don't have to worry about doing anything. All you have to do is put it on, crank this down.

Molly O’Shea56:35

OK.

Miguel Rivera56:35

And you'll be ready to go.

Molly O’Shea56:36

Let me try doing this one first.

Miguel Rivera56:37

Yeah. I'm going to do the same. I'm going to put on some PPE.

Philip Johnston56:46

Do you have, like, any kind of glass? I'm going to be quite far back.

Miguel Rivera56:49

You can use the same oneright there.

Philip Johnston56:50

This one?

Miguel Rivera56:50

Yep. You can put that on.

Molly O’Shea56:51

Who is she?

Miguel Rivera57:14

Very nice.

Molly O’Shea57:16

That one, my hand skipped a little bit.

Miguel Rivera57:17

Yep. That's fine. Still counts.

Molly O’Shea57:20

Beautiful.

Miguel Rivera57:20

We can do one more if you want.

Molly O’Shea57:21

OK. One more.

Philip Johnston57:22

Allright. Last one. This is when it counts.

Molly O’Shea57:23

Allright.

Miguel Rivera57:25

Stay nice and tight.

Molly O’Shea57:25

No pressure.

Miguel Rivera57:33

Closer.

Nice.

Philip Johnston57:50

Allright. You're hired.

Molly O’Shea57:51

Not bad.

Philip Johnston57:52

Damn.

Molly O’Shea57:53

Let's go.

Miguel Rivera57:54

Nice.

Molly O’Shea57:55

America needs welders.

Philip Johnston57:57

Whoo. Nice job.

Molly O’Shea57:58

Cool. Thank you, Miguel.

Philip Johnston57:59

You're very welcome.

Molly O’Shea58:00

This was so much fun.

Philip Johnston58:01

Good job.

Molly O’Shea58:04

That's my real reaction.

So on a scale of 1 to 10, like, what are we talking about?

Philip Johnston58:14

Here's you.

Adi Oltean58:14

Here's solid five.

Molly O’Shea58:15

Wow.

Adi Oltean58:16

See, guys, I've been doing this for 10 years, and I don't do a job like that.

Molly O’Shea58:21

Damn.

Adi Oltean58:21

That's very good. Just pay attention and take good instructions.

Molly O’Shea58:26

That'sright. We do.

Adi Oltean58:27

Damn.

Molly O’Shea58:29

That's great.

Cool. Thank you.

Philip Johnston58:34

They just lifted the satellite. I don't know if you want to maybe it's too late to get footage of that. But if you want, we just.

Molly O’Shea58:39

Yeah, let's go over there. So we just did the welding, and.

Philip Johnston58:42

You crushed it.

Molly O’Shea58:43

I'm a five. Out of 10.

Philip Johnston58:47

He didn't say out of 10. It could be out of five.

Molly O’Shea58:48

He did say out of 10.

Philip Johnston58:49

Did he?

Molly O’Shea58:50

Yes.

Philip Johnston58:50

I thought he said you're a solid five.

Molly O’Shea58:51

No, he said you're a solid five out of 10.

Philip Johnston58:52

Did he? OK. OK. OK.

Molly O’Shea58:54

It's like, damn. That's pretty good.

OK. But I was wondering, like, how does the flow change of how many people are working on the floor versus up in the offices through the different stages and processes of building out Starcloud 2?

Philip Johnston59:12

Yeah. So actually, most people that you can see are both engineering, and we have all the engineers make sure that they are hands-on with the satellite as well. So half the time, these people will be upstairs designing stuff on CAD.

The other half the time, they're down here fiddling with wires and testing stuff. We also have a technician team. That was Miguel. We got four technicians, some more coming on soon, maybe five now. I don't want to get it wrong.

And their job is, like, welding and fabrication, making actually producing the satellite. So yeah, Miguel's team.

The whole compute module here is an aluminum box that they in-house produced and fabricated.

Molly O’Shea59:57

And I am contributing to that.

Philip Johnston59:59

And you are contributing a huge amount.

Molly O’Shea1:00:02

Whenever you need me, let me know. I can come on.

Philip Johnston1:00:04

For your listeners, it is official. You have now done more welding at Starcloud than I have.

Molly O’Shea1:00:08

Wow. You got to really visit Miguel. I think he's waiting for you to.

Philip Johnston1:00:14

Yeah, yeah.

Molly O’Shea1:00:14

Put in some work.

Philip Johnston1:00:15

Yeah, yeah.

Molly O’Shea1:00:16

You're not doing enough.

Philip Johnston1:00:17

Yeah.

Molly O’Shea1:00:18

Bailey, tell us a little bit about yourself. I know we're in front of Starcloud 2, and something just happened, and you guys are testing things. But we'd love to learn more about you and how you contributed.

Bailey Montaño1:00:28

So I'm the engineering manager here at Starcloud. And what we're doingright now is a leak check of the prop system. Soright now, we have a fully fueled electric propulsion system, ION Thruster. And we are testing it after vibe to make sure that we didn't introduce any cracks or other leaks during the vibe test.

Molly O’Shea1:00:45

How did you come here? How did you get to Starcloud?

Bailey Montaño1:00:48

It was a bit of a long journey. So I started my career at SpaceX in aerospace. I spent about four years there. Then I did a couple of other side quests in, like, biotech and consumer product design. Those didn't really stick.

I moved on to fusion energy, which was really cool. But at the end of that three-year stint, I realized I'm a space nerd. I need to be working on space to be happy. And fortunately, living in Seattle, there's a ton of cool companies in the area.

But Starcloud really stuck out. Back then, they had a different name and got in contact with the founders super early on. And the rest is history.

Molly O’Shea1:01:17

What's your favorite thing about Philip?

Philip Johnston1:01:24

You can't do that. You can't do that.

Molly O’Shea1:01:27

What do you hate about him?

Philip Johnston1:01:28

What's your least favorite thing about him?

Molly O’Shea1:01:29

Yeah. What do you hate about him? What's your least favorite thing? We don't say hate.

Philip Johnston1:01:33

Got it.

Molly O’Shea1:01:33

What's your biggest challenge with Philip over here? Does he not give you enough attention? What's going on? Let's work this out on camera.

Bailey Montaño1:01:43

It's a two-sided coin or whatever. But, like, the office is very busy with tours and things like that all the time.

Molly O’Shea1:01:48

We got to go.

Philip Johnston1:01:49

There you go. There you go. There you go.

Molly O’Shea1:01:51

There you go.

Philip Johnston1:01:52

It's good and bad. That was the politest way to tell you to fuck off.

Molly O’Shea1:01:56

Oh, my god. Damn, Bailey. Give me the mic.

Oh, that's funny. OK. So what are you most looking forward to? What is your favorite part of the process?

Bailey Montaño1:02:08

I think the next thing I'm looking forward to most is obviously the launch, for sure. I'm going to be tremendously proud of this. Like, a lot of blood, sweat, and literal tears into this thing. As far as the whole design process goes, I would say kind of the test is my favorite part.

That's where the rubber really hits the road. So this recent vibration test was a really big one. And then the cooling system was another big one, where back when we were in Colorado not long ago, that was our first, like, full-up integrated test of the whole cooling system, which was kind of, like, my baby from day one.

So it was really cool to see that up and running too.

Philip Johnston1:02:40

So everybody always asks about what the hardest thing about Starcloud is, and it's the thermal system, these radiators in particular. And Bailey was responsible for designing and fabricating the radiators. And also, Bailey is responsible for this satellite being here.

So we had in the end state, we only had three weeks to do the final assembly of all of the satellite. And Bailey went down and basically built that bus from scratch.

Molly O’Shea1:03:02

Damn.

Bailey Montaño1:03:02

It was fun.

Molly O’Shea1:03:03

Where'd you build it?

Bailey Montaño1:03:04

In Colorado, in our bus provider's office.

Scaling & security1:03:06

Molly O’Shea1:03:06

Oh, my god. Allright. So we're just leaving the main facility. We're now going over here.

Philip Johnston1:03:11

Yeah, we're going to go to.

Molly O’Shea1:03:13

You're buying up the entire.

Philip Johnston1:03:15

We're building a bit of a campus here. This is definitely the place we need to be to build AI satellites, basically, SI satellites.

Molly O’Shea1:03:23

Yeah.

Philip Johnston1:03:24

So we've got now this middle section that we have now, where this will come online in November. And then we have access to the third one in February next year. And so this enables us to scale manufacturing for Starcloud 3.

And the reason we need so much space, one of the reasons is you have 100-meter or 400-foot deployables on Starcloud 3 that we need to test

the mechanisms on. But also, to manufacture something like 88,000, you know, we're going to need a way bigger facility.

Molly O’Shea1:03:57

I just think Bret's going to trip. I'm so sorry.

Philip Johnston1:04:00

It's fine. It's fine.

Molly O’Shea1:04:02

To manufacture 88,000. OK.

Philip Johnston1:04:04

Yeah, yeah, yeah. To manufacture 88,000, we're going to need a whole bunch more space.

Molly O’Shea1:04:08

So how many do you think you'll be able to produce a day?

Philip Johnston1:04:12

So we'll be up to 100 a week from what we've got here. So 10 a day or more than 10 a day after you. So this is one of the three spaces. And so we've got about 100,000 square foot that we can fit out for manufacturing.

So we're going to remove this wall, and we'll remove that wall. And then that enables us to.

Molly O’Shea1:04:33

This is huge. Oh, my god.

Philip Johnston1:04:36

Yeah, it's going to be it's going to be quite a sight to behold when this is up and running.

Molly O’Shea1:04:40

You should throw a Halloween party in here with this.

Philip Johnston1:04:42

Oh, yeah.

Yeah. We're going to do a we'll do an opening party sometime soon. So you're very much welcome.

Molly O’Shea1:04:51

Thank you.

Philip Johnston1:04:51

I know you're on the road all the time.

Molly O’Shea1:04:53

You never know where I land.

Philip Johnston1:04:56

Who knows? Maybe wooden building in three weeks.

Molly O’Shea1:04:58

I know. OK. So in here, it's going to look much different than the previous facility.

Philip Johnston1:05:05

It will look pretty similar, actually, to the previous facility.

Molly O’Shea1:05:06

It'll look the same.

Philip Johnston1:05:07

Except with a manufacturing line, like a proper in the end state, we want it to be like an auto manufacturing line. So if you when you see a Tesla factory, you see cars going down a line, it'll be exactly like that, except with Starcloud 3 chassis going down the line with various things being added.

Yeah.

Molly O’Shea1:05:24

How do OK. So this is a crazy question. How does Starcloud 3 get to Starship?

Philip Johnston1:05:35

We load them on the back of a truck and then drive them down the motorway.

Molly O’Shea1:05:39

That's it?

Philip Johnston1:05:40

That's it. Yeah. It's very similar to the way at the moment, just down the road from here is where the full Starlink facility is. So they literally load all those on the back of a truck and then drive them across the country to Florida.

Molly O’Shea1:05:53

Damn.

Philip Johnston1:05:53

Yeah.

Molly O’Shea1:05:54

OK. Wow. Allright. So one thing we haven't talked about yet is Starcloud has raised $450 million in total. What are you using the money for?

Philip Johnston1:06:04

Yeah.

Molly O’Shea1:06:05

How is the capital being utilized?

Philip Johnston1:06:07

Yeah. Well,right now, so launch is very constrainedright now, especially from 2028, 2029 onwards. So a portion of that cash is going to reserving launch slots. A bunch of it's going to fitting out these places and then hiring and materials and everything else.

Yeah, we're making about $1 million a week in interestright now.

Molly O’Shea1:06:30

Oh, my god.

Philip Johnston1:06:31

$1 million a month, sorry, in interest.

Molly O’Shea1:06:33

Wow.

Philip Johnston1:06:34

But soon.

Molly O’Shea1:06:35

You use Brex?

Philip Johnston1:06:35

We'll be spending.

Molly O’Shea1:06:36

Brex has a really good treasury product.

Philip Johnston1:06:38

We do use Brex, actually. And they do have a great treasury product. So there you go.

Molly O’Shea1:06:43

I know. I get a good interest on that.

Philip Johnston1:06:44

There you go. Yeah.

Molly O’Shea1:06:46

So one major thing that has been a topic of discussion as global competition heats up and satellites become the greatest asset for national security is what happens if someone tries to shoot it down or our adversaries get in contact with it or maybe there's a listening device.

Apparently, there was one at OpenAI. So how do you think through the national security concerns when it comes to chips and data centers in space?

Philip Johnston1:07:19

Yeah. So it's a great point and one we think a lot about. It's actually a lot harder to shoot down a satellite than it is to, for example, blow up a data center in Virginia,

which is surprising. Because and the reason is satellites are traveling at about 17,000 miles an hour. And so to target and have some kind of kinetic impact on a satellite at that speed is very difficult. And we know this.

One of the reasons we we have a pretty good case study, actually, from the Starlink satellites. So Starlink is being used in Ukraine and also Starshield. And it's not like the Russians are particularly happy about that. And so both in terms of cyber and in terms of the physical security of satellites, we can kind of see the tactics people are using already on Starship sorry, on Starlink.

And so, yeah, we're using the same kind of cryptography for

making sure that the satellites are secure from that perspective. And then, yeah, anything that approaches the satellite would be very visible. So anything bigger than one-inch cube, you could track in space. And so we would, yeah, we would see if somebody was tampering with our satellites.

And it would be considered an act of war. You know, there's this outer space treaty which governs what you can and can't do. And that would be considered an act of war on the US. And that's the purpose, the primary purpose of Space Force.

One of the key purposes is to, you know, they're developing interceptors and things to dissuade offensive action.

Molly O’Shea1:08:44

So as we just finished walking through the HQ, seeing the tracking of Starcloud 1, the development of Starcloud 2, and some of the early innings of Starcloud 3, what are you most looking forward to in the next 12 months?

Philip Johnston1:08:57

Definitely, the thing I'm most looking forward to is the launch of Starcloud 2. So that's going to happen in January. And it's going to be a huge proof point with the radiators and everything else we've designed in there.

Molly O’Shea1:09:07

Exciting. Well, thank you so much, Philip.

Philip Johnston1:09:08

Thanks so much for coming.

Molly O’Shea1:09:09

Cool.
