Launch Plus and the Real Economics of Orbit

Zach Martin

Welcome back to SPACE CAPITAL on KMKT IR Hub Radio. I'm Zach Martin, and today it's just you and me. In our last episode, Emily and I walked through the headline numbers from the Q2 2026 Space IQ report and the SPCX debut on Nasdaq. We're not going to replay that scoreboard. Think of today as the film room. A scoreboard tells you who's ahead. The film tells you why, and whether the team can keep doing it when the crowd goes home. So we're going to look at how capital is actually being deployed at the level of individual companies, and we'll sort what looks like durable, recurring utility from what looks like a great story waiting for its unit economics.

Zach Martin

Before the film, I need to give you just enough of the scoreboard that everything else makes sense. According to Space Capital's Space IQ dataset, which tracks more than 3,000 companies across three layers called Infrastructure, Distribution, and Applications, about $488 billion has been invested in the private space economy since 2009. One note on sourcing. Space IQ is a quarterly report from Space Capital, which is also an active investor across all three layers, and several of the companies we'll discuss today are in its portfolio. That doesn't make the data wrong. It does mean we should read it the way you'd read a coach's own scouting report, useful, detailed, and not neutral. I'll flag where a point is Space Capital's interpretation instead of a plain fact.

Zach Martin

Here is the number I'd put on your wall. Since 2009, pure launch has attracted $18.3 billion. That's roughly 4% of all the capital invested in the space economy. Satellites took 81%. Let that sit for a second. The part of the industry that gets the cameras, the rocket landing on the barge, the countdown, drew about four cents of every investment dollar. The money has gone where the repeatable revenue is, into the things you put in orbit and what they let you sell once they're up there.

Zach Martin

That's the foundation for a new category Space Capital added to its data this quarter, and it's the most useful single idea for today's episode. They call it Launch Plus. The plus is the whole point. The thesis is that launch alone doesn't make a great business, and that access to orbit is a strategic advantage that lets a launch company walk into higher margin businesses, like orbital compute, communications, and lunar markets. Their blog on the category says the value of reaching orbit is what you own once you're there. I'd call that the interpretation, but the quarter gave it some evidence. Space Capital reports that Launch Plus led all Infrastructure investment at $14.6 billion year to date, and drove 71% of the quarter's top Infrastructure deals, anchoring what they call the largest Infrastructure quarter on record.

Zach Martin

Now let me give you the discipline lesson before we go any further, because this is where listeners get hurt. When a category gets a new name and a record quarter in the same breath, it's tempting to assume the name explains the money. Sometimes the name is just a label stuck on the money after it arrived. So I want you to hold two questions in your pocket for the whole episode. First, what recurring thing does the customer pay for, again and again? Second, what has to be true physically and financially for that to keep working? If a company can't answer both, it's a story. If it can, it's a business. Let's use those two questions on everything.

Zach Martin

Start with the liquidity event that changed how everyone has to think. SpaceX debuted on Nasdaq under the ticker SPCX on June 12, 2026, and closed its first day up 19%, at a market capitalization north of $2 trillion. Space Capital describes it as the largest IPO in history. And here's a detail I find more telling than the price. The S one filing doesn't describe a rocket company. It describes, and this is a quote from the filing as Space Capital presents it, the only company building the integrated hardware and software infrastructure of the future across space, connectivity, and AI. The market agreed with that framing. It priced the stock like an AI infrastructure company that happens to launch rockets, not like a launcher.

Zach Martin

Then look at what the company did with its new currency, because that's the part that moves capital flows. According to Space Capital's opening letter, SpaceX merged with xAI ahead of the IPO. It bought an option to acquire Cursor, then exercised it in a $60 billion all stock deal days after the debut. In one quarter it sold AI compute to Anthropic and Google at roughly $26 billion annualized, which the letter says more than doubled the revenue it took 23 years to build. It plans to make AI chips with Terafab to power orbital data centers. And it launched a $25 billion notes offering, following big tech into the debt markets to fund an AI buildout. Before this year, the letter says, SpaceX had made four acquisitions in its history, none larger than $525 million. In Q2 alone it added two more, including that $60 billion deal priced in its own record stock.

Zach Martin

Think about what that means mechanically. A private company can only spend what it has raised. A public company with a rich stock can buy other companies with the stock itself. That's a different kind of power, like the difference between a player who has to save up for equipment and one who can trade his jersey number for a roster spot. Space Capital's framing is that the currency flows both ways. The same letter says Rocket Lab is buying Iridium partly with its own stock. I'd add a coach's caution. Stock as currency works beautifully when the stock is rising and gets painful when it isn't. Space Capital's own newsletter lists a MarketWatch headline in its press section, asking why the stock is now cratering. I haven't seen the underlying article, so I won't characterize it. But the existence of that headline is a reminder that a currency has a price, and the price moves.

Zach Martin

The second half of the public market bridge is exits. For a decade the knock on the space economy was that investors couldn't get their money out. Space Capital argues that argument ended in Q2. Their claim is that the SpaceX IPO is the largest liquidity event in venture capital history, surpassing the full year exit value of 2021, the previous high water mark, and generating more exit value than every venture backed IPO of the past decade combined. HawkEye 360 also listed, and Blue Origin acknowledged for the first time that it will need outside capital to scale and didn't rule out going public. Now, one company supplied most of that exit value. That's a fact worth keeping in view. A single giant exit can prove that the door opens. It doesn't prove the door stays open for the next dozen companies, and that's what allocators will test over the next few quarters.

Zach Martin

Let me show you the Launch Plus pattern in the deal that best illustrates it, and then I'll explain why I think it's the most important asset lesson of the quarter. Rocket Lab had a busy stretch. According to Space Capital, it joined the Nasdaq 100, it broke its own launch turnaround record by more than ten hours on a U.S. Space Force mission, and it closed its acquisition of Mynaric, adding laser optical terminals and its first European entity. Then came the headline, an $8 billion acquisition of Iridium, at $54 per share in cash and stock, expected to close in mid 2027. Amazon, in the same quarter, paid $11.6 billion for Globalstar. Space Capital says it was on the same logic.

Zach Martin

What logic? Spectrum. Radio spectrum is a finite resource. Nobody can manufacture more of it. Space Capital calls it the scarcest asset in the space economy, and notes that Iridium's L band licenses are globally harmonized, meaning they work everywhere on Earth rather than country by country. Pair that with Iridium's 2.5 million subscribers and decades of government and safety of life contracts, and Rocket Lab doesn't just get a satellite network. It gets an installed base in the markets Space Capital says are heating up fastest, direct to device, positioning and timing, and aviation.

Zach Martin

Here's my analogy. A rocket is a truck. Trucks are essential, but if all you own is trucks, you compete on price with every other truck. Spectrum is the land under the warehouse. You can't print more of it, and everyone who wants to operate in that neighborhood has to deal with whoever holds the deed. When Rocket Lab spends $8 billion on Iridium, the interpretation, and it is an interpretation, is that it's trading a good truck business for some land. Whether $8 billion is the right price is a question the next couple of years will answer, and the deal isn't expected to close until mid 2027, so there's execution and regulatory time between announcement and ownership. But the direction tells you where the smart operators think the durable margin lives.

Zach Martin

Let me bring in the record numbers, because they frame everything we're about to do. Space Capital's data, as summarized in the research I'm working from, shows 2025 closing at a record $55.3 billion, anchored by a $17.0 billion fourth quarter across 135 rounds. The first half of 2026 then brought more than $67.6 billion, with $36.0 billion in Q1 and $31.6 billion across 129 companies in Q2. SpaceNews, separately, ran a headline that satellite investment set an annual record halfway through 2026, with the research brief putting that figure at $8.1 billion in six months. So the first half of this year already exceeds all of last year in total dollars. Capital isn't scarce right now. Discipline is. And that's the lens for the rest of the show: when money is abundant, the question isn't who raised the most, it's who can turn the money into something customers keep paying for.

Zach Martin

Here's the road map. We have four deep dives. First, Eclipse Space and the idea of a fabless satellite company, which asks whether you need to own a factory to own a constellation. Second, Xona Space Systems and what happened to commercial positioning and timing after the Pentagon cancelled its resilient GPS program. Third, Impulse Space and the shift from simply putting lots of satellites up to moving them around, under the Golden Dome defense architecture. And fourth, the off Earth economics, with Muon Space's honest assessment of orbital data centers and Lunar Outpost's rover milestones. Same two questions each time. What do they sell repeatedly, and what has to be true for it to work.

Zach Martin

Let's start with a company that has thirty employees and no factory, and is talking about building constellations. That's Eclipse Space, which came out of stealth on stage at the 13th annual Space Capital Summit at Nasdaq MarketSite, two weeks after the SpaceX IPO. Space Capital led its seed round, so again, keep the disclosure in mind. The CEO is Derek Huerta, who spent seven years at SpaceX as a satellite payload engineering manager, leading the team behind the phased arrays that link Starlink satellites to the ground. He was interviewed by Tom Whayne, a Space Capital operating partner who was formerly CFO of OneWeb and chief strategy officer at Maxar.

Zach Martin

The first thing that struck me is who works there. Roughly half of Eclipse's 30 employees came from Starlink, and Space Capital says 13 of them are from the years the program was still called Satellite Development. They work out of Redmond, Washington, where SpaceX builds Starlink satellites. First customer hardware ships later this year, and a demonstration spacecraft follows in 2027. So this isn't a PowerPoint. It's a small team that watched one of the most successful hardware programs in history from the inside and then decided to do something different with what they learned.

Zach Martin

To understand what different means, you need the scale problem that Whayne laid out at the start. In fifty years of satellite communications, only two companies have organically reached a billion dollars of connectivity revenue. Inmarsat needed thirty years. SpaceX needed a handful. If you're an investor, that should stop you cold. It says the business of satellite connectivity has historically been brutally hard to scale, and then one company broke the pattern. The natural reaction is to ask what it did and whether anyone can copy it.

Zach Martin

The industry's answer for years has been vertical integration. SpaceX builds its own rockets, satellites, and terminals, so everyone else decided they should own the factory too. Huerta's argument, as Space Capital recounts it, is that vertical integration was never the source of the advantage. He named two things. First, SpaceX treated the user terminal, the spacecraft, and the launch vehicle as one system, so engineers could make trade offs across all of it rather than optimizing one slice and passing the problem along. Second, it imported mass manufacturing discipline from industries that had already solved volume production, designing for manufacturability from the start instead of retrofitting it later. Huerta's line was, you don't actually need to own a factory.

Zach Martin

Let me translate that for anyone who has ever tried to build a habit. Imagine two people who want to get fit. One buys a house with a built in gym, a pool, a sauna, everything. The other joins a gym, has a great program, and spends the money on a coach. The first person has a beautiful asset and a monthly obligation to use it. If they miss a few weeks, the cost of the idle gym still shows up. The second person pays for what they use. That's roughly the logic Eclipse is applying. A factory isn't just an asset. It's an obligation to fill it.

Zach Martin

Space Capital's write up spells this out. A factory obligates you to fill it. SpaceX and Amazon generate their own demand, so for them a plant makes sense, because they already know the satellites will be bought, by themselves. Everyone else builds the plant first and then hunts for customers. Idle capacity raises unit costs, and higher unit costs price out the very buyers who would have filled the plant. The moat turns into an anchor. I think that's a sharp observation, and notice it's an economic argument, not a technology argument. It says the problem isn't that other companies can't build satellites. It's that building them in a captive factory forces a cost structure that only works for a company with captive demand.

Zach Martin

So what's the alternative? The comparison Space Capital makes is to chips. Eclipse runs it the way Apple runs Foxconn and NVIDIA runs TSMC. Fabless means you own the design, the architecture, the integration, and the on orbit operations, and someone else owns the plant. Eclipse engineers the spacecraft so that building it doesn't demand highly skilled labor, which is what lets contract manufacturers take on the work. Or as the Space Capital write up puts it, own the design and the supply chain, let someone else own the plant.

Zach Martin

There's a detail in the story I love because it reveals the actual priority. Before Eclipse had a logo, a website, or an office, Huerta had someone on a plane building the supply chain, and he had already met heads of state. An advisor told him he was doing it backwards. The supply chain, it turned out, was the hard part. The logo could wait. That's the kind of sequencing I respect. Founders who start with the brand are practicing for a pitch. Founders who start with the supply chain are practicing for delivery.

Zach Martin

Now let's talk about who the customer is, because that's where the capital flow shifts. The pitch is that this puts constellation ownership within reach of buyers who could never build one. Think regional telecom operators, and think countries. Huerta picked up a point from NASA's Deputy Administrator earlier in the same day, that in space the usual order has inverted. Commercial operators built the infrastructure and governments became the tenants. Countries are discovering they depend on capability they neither own nor control. And Huerta laid out the options as he sees them. China's answer, exported along the Belt and Road, is to build and finance your constellation and keep the strings. The American answer has been leased capacity on someone else's network. His third way is infrastructure built in country, on what he described as an ITAR free platform, which the customer owns and operates.

Zach Martin

I want to flag the line between fact and interpretation here. That a team came out of Starlink, that the company has 30 employees, that hardware ships later this year and a demonstrator flies in 2027, those are the company's stated facts as reported by Space Capital. The claim that this model puts constellations within reach of sovereign buyers is Eclipse's pitch, and the claim that it's ITAR free is Huerta's description, not something I've been able to verify independently. Also note a gap I haven't seen filled. Space Capital's write up says the full conversation covers the financing problem behind billion dollar constellations, but the summary I have doesn't tell us how that problem gets solved. That's the question I'd press hardest, because a fabless model removes the factory from the balance sheet, not the cost of the satellites or the launches.

Zach Martin

The thing underneath all of it is a single metric, and I wish more companies would organize themselves around one number like this. Dollars per throughput delivered in orbit. Drive that down far enough, the argument goes, and serving a rural user from orbit costs less than serving them from a tower. At that point, the billions telecom operators spend each year on radios and towers could redirect upward. Eclipse is starting with direct to device service, meaning connecting ordinary phones to satellites, because it's the hardest version of the problem, and the stack that solves it should carry over to broadband and orbital compute.

Zach Martin

Here's why this belongs in a conversation about capital flows. The old model concentrated capital in factories and in the handful of companies that could afford them. If the fabless model works, capital splits. Some goes to design and architecture teams. Some goes to the contract manufacturers who get the volume. And a lot of it goes to the buyers, who suddenly have a new asset class they can own. That's what Space Capital means when it says the infrastructure layer itself becomes something you buy rather than a program you run.

Zach Martin

Let me give you my coach's view, and I'll give you the skeptic's cut along with the optimist's. The optimist's version is that the semiconductor industry did exactly this, and the world got better chips, faster, from companies that didn't have to carry plants. It's a strong analogy. The skeptic's version is that chips are a mature, standardized discipline with decades of process knowledge and a deep contract manufacturing base. Satellites for megaconstellations are not there yet. Making a design that unskilled labor can assemble is a hard engineering target, and the first demonstration spacecraft in 2027 is the first real test of whether the target is hit. What I'd watch is not the next funding announcement. I'd watch whether customers sign for hardware that ships later this year, and whether the cost per unit of throughput lands where Huerta says it can.

Zach Martin

And the discipline question. What does Eclipse sell repeatedly? On the evidence in front of me, it sells design, integration, and operations expertise, plus hardware to customers who own the result. That could become recurring, through operations and follow on constellations, but today it's mostly a promise of a first delivery. So I'd classify it as a credible architecture with an unproven revenue cycle. That isn't an insult. Every business is in that spot before it ships. The key is to not confuse the spot for the finish.

Zach Martin

Next up, the layer that most people use a hundred times a day without noticing. Positioning, navigation, and timing, or PNT. GPS is the famous version of it. When your phone knows where you are, that's PNT. When a bank timestamps a trade, when a cell network hands your call from one tower to another, when a farm tractor steers itself down a field, that's PNT too. Space Capital's materials say GPS alone has generated trillions of dollars in economic value, and they call satellites the invisible backbone for the world's largest industries. What I like about this layer is that it's a clean example of a pattern Space Capital describes again and again, which is that infrastructure gets built, becomes invisible, and then becomes the foundation for the next commercial layer.

Zach Martin

Here's the problem. GPS satellites sit in medium Earth orbit, roughly 20,000 kilometers up. From that distance, the signal arriving at your receiver is very weak. That's fine in an open field, and much less fine in a city, where tall buildings degrade the signal. It's also a serious problem in a conflict, because a weak signal is easy to jam and easy to spoof. Spoofing means a bad actor feeds your receiver a false position. The research brief I'm working from lists extreme susceptibility to electronic warfare, spoofing, and jamming as the core structural vulnerabilities of legacy GPS.

Zach Martin

And here's the number that tells you the market is already voting. The same materials say enterprises spend more than $20 billion a year on ground augmentation and workarounds to make up for GPS limitations. That's a figure from Space Capital's analysis, so treat it as their estimate, but think about what it implies. When customers are spending twenty billion dollars a year to patch a free service, they are telling you that free isn't good enough. The patching is an existing budget line. That's the most attractive condition for a new entrant, because you don't have to create demand. You have to capture spending that already exists.

Zach Martin

Now the policy event. In early 2026, according to the research brief, the U.S. Space Force cancelled its billion dollar Resilient GPS program, known as R GPS. The significance is the direction of the pivot. Space Capital describes it as pivoting to embrace existing commercial PNT solutions instead of building new government owned constellations. I want to be careful with what that means. It doesn't say the government is abandoning GPS, and it doesn't hand any one company a contract in the material I have. What it does say is that a budget line that would have gone into a government built constellation is now open to commercial providers. For a young company, that's a market that just moved from impossible to plausible.

Zach Martin

The company at the center of this is Xona Space Systems, founded by Stanford aeronautics and astronautics engineers Brian Manning and Dr. Tyler Reid. Its system is called PULSAR, and the core design choice is simple to describe. Instead of sitting 20,000 kilometers up, PULSAR operates in low Earth orbit, which is about twenty times closer to the surface. Physics hands you a gift for that. Signal strength falls off with distance, so a closer transmitter can be heard far more strongly. The brief says Xona's signals are up to 170 times stronger than GPS, and that the system delivers two centimeter accuracy, native cryptographic authentication, and a patented distributed clock architecture. Those are company claims relayed through Space Capital's write up, and I haven't seen independent test data, so hold them as claims. But the logic points the right way. A stronger signal is harder to jam, and authentication built in from the start makes spoofing harder.

Zach Martin

Let me give you an analogy for the distance effect. Imagine trying to hear a friend whispering from across a stadium versus across a table. You don't need better ears. You need to be closer. LEO PNT is moving the speaker to the table. Of course, a closer satellite moves faster across the sky, and you need many more of them to cover the planet. That's where the capital goes. The plan, per the brief, is a 258 satellite constellation. It's a different business from GPS. GPS is a few dozen satellites, each expensive and built to last. Xona is betting on a larger number of cheaper satellites in lower orbit.

Zach Martin

The milestones on the way there are specific, and I like specifics. In June 2025, Xona launched and commissioned a production demonstrator called Pulsar Zero, which operated with live sky signals. In March 2026, it closed a $170 million Series C to scale a manufacturing line in Burlingame, California. And it has a partnership with Belgium's Aerospacelab to deliver eight microsatellites for initial commercial rollouts by 2027. Think of the sequence. Demonstrator, then funding, then factory, then first production satellites. That's the order you want to see. Each step retires one kind of risk before asking for the next dollar.

Zach Martin

Now here's the part I think is the most underrated detail in the whole story, and it's about adoption, not satellites. A new navigation signal is useless if nobody's receiver can use it. Historically, that has been the killer. You build a beautiful system and then wait years for device makers to redesign their products. The research brief says Xona's partners, including Trimble, Furuno, Safran, the UK's National Physical Laboratory, and the Air Force Research Laboratory, are adopting Pulsar through software or firmware updates to their receivers, not new hardware. If that's accurate, and I'd treat it as a stated plan rather than a completed rollout, it matters enormously. It lowers the switching cost for the customer to a software update. Compare that to asking a farmer to rip out a tractor's guidance system.

Zach Martin

So who pays, and how often? This is where I try to separate a recurring revenue story from a one time contract story. PNT is a service. It's like a subscription for knowing where you are and what time it is, with accuracy and integrity guarantees. Precision agriculture is one example in the materials. Space Capital says it saves 500 million gallons of water annually in the United States. Others include drone logistics, financial timestamping, and cellular handoffs. Each of those customers needs the service every second, forever. That's about as recurring as revenue gets. And the contracts that tend to go with it, resilience for defense and critical infrastructure, are the kind of sticky enterprise relationships that compound.

Zach Martin

Now the coach's caution, because I'd be a bad coach if I only showed you the highlight reel. First, a cancellation is not an award. The Pentagon stepping back from building its own constellation opens a door, but several commercial players could walk through it, and the government may want multiple sources. Second, building 258 satellites is a long haul, and initial commercial rollouts by 2027 means the full network is further out still. Third, a stronger signal solves some vulnerabilities and not others. I'd want to see how the system performs under real world interference, not just in a demonstration. None of that kills the thesis. It tells you where the homework is.

Zach Martin

Let me tie this back to capital flows. Look at how three things are layered in Xona's story. A government cancels a program, which shifts public demand toward commercial supply. A venture round, the $170 million Series C, converts that shift into a factory and a launch schedule. And downstream partners adopt through software, which converts satellites into revenue without a hardware reset. That's what a healthy flow looks like. Public demand signals, private capital builds, and customers adopt with minimal friction. It's also exactly the thing that was missing for years in space, and it's why Space Capital keeps pointing to GPS, then GEOINT, then SatCom as the pattern.

Zach Martin

And one more connection to the Launch Plus idea from earlier. Remember that Rocket Lab's $8 billion Iridium deal was explicitly aimed at positioning and timing, among other markets. So PNT is now a place where a launch company is buying its way in and a startup is building its way in. That's a sign of a market with real money in it. When a launch company with an $8 billion check and a seed stage satellite company both aim at the same service, you should expect competition, consolidation, and, if you're a customer, better options. If you're an investor, you should expect the winners to be the ones with the signal, the receivers, and the contracts, not the ones with the best slide deck.

Zach Martin

Now let's move from where you are to where you can go. For years, the dominant story in orbit was proliferation, put up so many satellites that no adversary can take them all out. It worked in low Earth orbit, where Starlink and others made constellations of a thousand spacecraft routine. But this quarter's defense conversation says proliferation has a limit, and the limit is geometry. The source for this section is a conversation at the 2026 Space Capital Summit titled Shield and Spear: The Age of Maneuver. On one side was Marcia Holmes, Deputy Director of Golden Dome for America, whom Space Capital calls the architect. On the other was Eric Romo, President and COO of Impulse Space, a Space Capital portfolio company, whom they call the builder.

Zach Martin

Start with why the government is doing this at all. Holmes did not soften the picture. The threat is real, complex, and growing, she said. She pointed to Russia fielding hypersonic and Avangard systems and using them on the battlefield in Ukraine, and to China being projected to field over 1,000 intercontinental ballistic missiles, doubling its arsenal. Her words were that the homeland is no longer a sanctuary. The practical consequence is where defense has to live. For sixty years, the United States has defended itself mostly from the ground, with radars, sensors, and interceptors rooted to the Earth. Holmes said those can't see the newest threats early enough, so you have to go to space to see them from launch through their whole flight path, and to position interceptors before a missile deploys its warheads or decoys.

Zach Martin

Now, why is that possible today when it wasn't before? Romo's answer began where every space conversation begins, with launch. The last time the country seriously discussed intercepting missiles from space was the 1980s, when reaching orbit cost a fortune. Today, a constellation of a thousand spacecraft in low Earth orbit is routine, thanks to Starlink and others. And that maturity spreads to the companies building the hardware. Romo said he's not doing this for the first time, he's doing it for the second or third time and scaling up. That is a line I'd underline for any investor. Companies on their second or third pass at building hardware behave very differently from first timers.

Zach Martin

Here's the doctrinal shift, and it's the heart of this chapter. Proliferation works where the space you're defending is small enough to fill. But Romo pointed out that medium Earth orbit and geostationary orbit are, in his words, literally a million times bigger than low Earth orbit. Blanketing orbits that vast with enough satellites to cover every point at every moment is, he said, completely untenable. And those high orbits are where a lot of the crown jewels sit. GPS is in medium Earth orbit. Missile warning and secure communications are in geostationary orbit. Most U.S. investment has historically gone to those high energy orbits, and now those assets are under pressure for the first time.

Zach Martin

If you can't defend them with numbers, you defend them with agility. Think about a soccer match. You can't cover a huge field by lining players shoulder to shoulder. You need players who can sprint to where the ball is going. Romo pointed to recent reports of three Russian craft maneuvering around a U.S. imaging satellite over Ukraine as a sign that everything up there now has to be able to move. I'll note that's his citation of reports, not something I can confirm. But the logic is clear. If an adversary can move a spacecraft next to yours, a satellite that can't move is a spectator.

Zach Martin

That's where Impulse Space comes in, and it's a good example of a company whose products match a doctrinal need. According to Space Capital, Impulse is flying the capability now. Its Victus Surgo and Victus Salo vehicles are both Space Domain Awareness missions, both in the clean room at the time of the conversation, and built for fast, high energy repositioning. One is bound for a geostationary transfer orbit and one for low Earth orbit. And then the demonstration that I think matters most. In December, together with Starfish Space, Impulse completed a fully autonomous rendezvous in orbit, one vehicle approaching another using a single camera, with no joystick, no human steering from the ground. The research brief dates that to late 2025.

Zach Martin

Let me make that concrete. Autonomous rendezvous means a spacecraft finds another one, judges the relative motion, and closes in on its own. A single camera is a modest sensor for a very hard job. Romo explained the difficulty plainly. The ability to reach out and touch an asset when it wants to be touched is one thing, he said. When it does not want to be touched is another. Closing velocities run into thousands of meters per second, and hitting a target is not so much a bullet hitting a bullet as, in his words, maybe a hundred times harder than that. I'd treat that as vivid rhetoric from a builder, but it conveys the point. This is the difference between a demonstration and a weapon system, and the gap is large.

Zach Martin

Now the money. This is where the story gets interesting for allocators. A recent Congressional Budget Office estimate, as reported in the write up, pegged space based interceptors at roughly $22 million a shot. Romo put that in context. Ground based interceptors like the SM three and the GBI run from $30 million to nearly $100 million apiece. So $22 million isn't outrageous by historical standards. But now multiply by the thousands of interceptors a real architecture would need, and the number gets very large, very fast. Holmes was direct about the constraint. General Guetlein, who leads the program, has said publicly that if space based interceptors cannot be bought affordably and at scale, they will not be part of Golden Dome.

Zach Martin

Read that again, because it's one of the most important sentences in the defense space story. The program lead is saying the technology only gets a place if it's affordable at scale. That's not a blank check. It's a cost discipline mandate, and it explains Holmes's fix, which is procurement itself. Because Golden Dome is net new, she said, it can start from a clean sheet rather than fifty years of cost plus habit. The program is offering prize based competitions, rewarding demonstrated performance instead of paperwork, and dealing directly with builders to compress timelines. Romo's reaction, and I love the bluntness, was that you set an ambitious goal, and if you get it, you get paid a bunch. If you don't, sorry.

Zach Martin

Why does that matter for capital flows? Because cost plus contracting pays you for effort, and prize based contracting pays you for results. Under cost plus, a company's incentive is to keep the program going. Under a prize, a company's incentive is to hit the milestone with the least cash burned. That changes who can compete. A venture backed company with a lean team can take a milestone contract in a way it never could take a decade long cost plus program. It also changes how investors underwrite. You're no longer betting on a company's relationships. You're betting on its test results.

Holmes also described where the opportunity sits, and I think it's the practical takeaway for founders and investors listening. She and Romo described a layered defense running from space to land to sea, with a long list of pieces still to be built. Low cost kinetic and non kinetic interceptors. AI and autonomy for automated decision making. Track fusion, meaning combining data from many sensors into one picture. And low latency communications to stitch it all together. Golden Dome has what Holmes called an ecosystem hub, meant to be a single front door for companies to find where they fit, with primes subcontracting to non traditional companies inside its command and control consortium rather than the other way around.

Zach Martin

A moment on the tactical edge, because it ties to a company in Space Capital's portfolio that shows the same logic one layer down. Guardian RF builds handheld signal detection units called Scout and a mesh network called Mosaic, linked through Starlink, which Space Capital describes as battle tested in Ukraine. The same source offers a striking cost comparison. In 2024, it says, a 50 kilogram payload drone cost the same as a single dummy 155 millimeter artillery shell. I'm relaying that as Space Capital's figure. But think about the lesson it implies. When defenders face cheap, numerous threats, the cost of defense per engagement is the whole game. That's the same affordability constraint General Guetlein is applying to space interceptors, just at a different altitude.

Zach Martin

Let me draw the distinction I promised at the top. What's genuine recurring utility here, and what's still speculative? The utility side is the space domain awareness, the repositioning, the ability to move and refuel and inspect assets that already exist and already matter. Those are services customers can pay for repeatedly, and the demand signal is policy driven. Space Capital describes geopolitical imperatives as a permanent floor under space investment, and the Q4 2025 review puts it in similar terms, saying strategic competition established a permanent floor and that maneuverability is becoming the most valuable currency in orbit. That's Space Capital's interpretation, but the Golden Dome conversation supports it.

Zach Martin

The speculative side is the interceptor architecture itself. A $22 million per shot estimate is an estimate. A fielded capability by 2028, which is the target Space Capital reports for Golden Dome, is a target. And Romo himself gave the caution that I'd tape to every desk. The early demonstrations are not what pays off. Long term production is, and confidence in it will, in his words, ebb and flow with news cycles and OMB reports. OMB is the Office of Management and Budget. So a builder is telling you that the biggest risk isn't the physics. It's the budget cycle. The signal to watch, both speakers agreed, is not press releases but contract awards, test campaigns, and the steady expansion of the space budgets that quietly underwrite it.

Zach Martin

This is the kind of discipline I'd apply as a coach. Press releases are warm up. Contract awards are the game. If you're following this sector, build a habit of checking three things every quarter. Did a program convert a demonstration into a funded production contract? Did the unit cost move toward the stated target? And did the company deliver on the date it gave you last time? Those three questions will keep you out of most of the traps. A maneuvering spacecraft is a beautiful thing. A maneuvering spacecraft with a repeat customer is a business.

Zach Martin

For our last stretch, let's go off Earth and ask what the economics actually look like when the ambition gets bigger. Two stories. First, orbital data centers, through the lens of Jonny Dyer, CEO of Muon Space, who sat with Space Capital partner Tom Ingersoll at the 2026 Summit for a conversation titled The Honest Case. Second, the Moon, through Lunar Outpost and the first human rated rover contract awards. They share a theme. In both, the physics may be fine. The question is whether the economics close.

Zach Martin

Orbital data centers first, because the pitch is seductive and I want you to hear why. As terrestrial AI runs into power shortages and water fights, the idea of moving compute above the grid has gone from fringe to boardroom fast. Dyer lists three real advantages. Power, because in the right orbit the sun never sets, and he said you can pick orbits where the sun is baseload power, always on in a way it fundamentally can't be on Earth. Cooling, because deep space is a nearly absolute zero background you can radiate heat into, without water, real estate, or permitting fights. And regulation, because there are no county councils in orbit. If you come up with a regulatory approach, he said, it's a global approach, literally.

Zach Martin

Then comes the honesty. Dyer says the physics works and the economics do not yet. At today's launch prices, a large orbital data center costs roughly eight to ten times more than its terrestrial equivalent. To close that gap, you need launch cost down about five times and launch cadence up about ten times. For scale, he noted that Falcon 9 flies something like 100 to 200 times a year, and the math wants 500 to 1,000. He added that luckily that's also the scale of launch you'd need to put gigawatts of data centers in space, so the two numbers move together. And it all comes back, he said, to the cost of launch.

Zach Martin

Let me put that in a framework a coach would use. Imagine you're training for a marathon and someone tells you that you can run it in three hours if only your current pace were twice as fast and you could train ten times as often. You'd say, that's not a plan, that's a different athlete. But then suppose that someone is also building the track, the shoes, and the training facility that gives you exactly that pace and frequency, because they need it for a different reason. Then the plan is suddenly coherent. That's Dyer's point. The launch scale that makes orbital data centers affordable is the same scale that a lot of other businesses, including Starship driven launch and the Launch Plus companies, are already trying to reach.

Zach Martin

Now the objections, and I appreciate that Dyer went through them one by one. Communications is the first. Moving data between spacecraft is easy, he said, and the throttle is the regulated, bandwidth limited link to the ground. But for AI workloads, the heavy traffic stays machine to machine. Starlink's inter satellite links already run about 100 gigabits per second, roughly an order of magnitude short of the terabit fabrics inside a data center. A gap, not a wall. Radiation is the second. He argued it has quietly inverted, because terrestrial chips are already hardened against cosmic ray bit flips, since data centers see those at scale on the ground. His favorite proof was that Google's fleet effectively became the world's largest cosmic ray telescope. These problems are getting easier over time, he said, not harder.

Zach Martin

But he would not wave away the hard part, and neither should we. Space is still a hostile environment, he said. These are autonomous robots sent to space that have to take care of themselves, and if you don't get that right, they fail, and we can't go up and fix them. The deeper challenge is integration, stitching hardware, sensing, compute, and software into one system that works in orbit. Integration is one of the hardest problems in technology, he said, and we just haven't done it enough in space to get it to the point where it's muscle memory. I love that phrase, muscle memory. It's the right metaphor for the whole industry. You don't get skill from knowing the move. You get it from repetitions.

Zach Martin

So what's the timeline? Dyer was careful. It's not a switch, it's a progression, he said. Elon Musk says all of it is going up, and Dyer's response was that it may very well be that Musk is right and in three years all data centers are in space, that you may not be right about that timeline, but that in some ways it doesn't matter, because the secular trajectory points that way. Notice what he did there. He didn't dispute the destination. He disputed neither the destination nor the date out loud, and he left the date to the reader. Then he gave the near term path. National security workloads and data that is simply better kept in orbit will pull the first systems up early, and from there a flywheel of cheaper launch and rack like satellites compounds.

Zach Martin

I want to connect this to SpaceX's quarter, because it's the cleanest real world signal. Space Capital reports that SpaceX sold roughly $26 billion of annualized AI compute to Anthropic and Google, and plans to make AI chips with Terafab for its orbital data centers. Those two facts are not the same kind of fact. The compute sales are reported revenue, as Space Capital describes them. The orbital data centers are a plan. So the lesson is to separate the part of the story that's earning from the part that's aspiring. And I think the Space Capital letter's deeper claim is the one to hold on to, that energy and compute are the two bottlenecks governing AI, and space is being pulled toward them. That's a reasonable thesis. It's still a thesis.

Zach Martin

Here's what I find most useful in Dyer's talk. He said orbital data centers are the ice above the water, and there's an iceberg below. And the iceberg is the convergence of space and terrestrial technology. For seventy years, he said, space behaved like the Galapagos, a separate ecosystem detached from the mainland of the economy. That isolation is ending, and he warned that those who don't have a strategy there are going to get left behind. So rather than chase the compute farm headline, look at how Muon builds. The research brief describes a full stack Space as a Service approach. MuSim for mission digital twins. MuSat, a modular satellite bus. MuCore, a software defined instrument controller. MuOS, cloud native space middleware. And MuDash, a browser based command and control. The point of the stack is that a customer can order an outcome and Muon handles the spacecraft.

Zach Martin

And the proof point is FireSat. According to the brief, it's a constellation of more than 50 satellites carrying six band infrared sensors, scanning wildfire zones every nine minutes at five meter resolution, and it brings together Google Research, Cal Fire, the Moore Foundation, and the Environmental Defense Fund. Dyer's own description is that crews get full situational awareness, overhead views of where the fire is, how hot it's burning, and how fast it's moving, updated hourly, day and night. I'll flag one thing. The nine minute figure in the brief and the hourly update in Dyer's description reflect different aspects of the system, scanning cadence for a zone versus refreshed situational awareness for a crew, and I wouldn't merge them into one claim. What I'd emphasize is the product. It's not a picture. It's a recurring, decision grade service that a fire agency can use every season. Also in the news, Bloomberg reported that Muon raised $250 million with Google and Salesforce backing.

Zach Martin

Compare that with the data center story. FireSat is a real customer with a real, repeating need, in orbit now, built with commodity style hardware and software. The orbital data center is a larger prize with a harder cost problem. A disciplined investor can hold both in the mind and still know which one is paying the bills today. That's the coach's habit, build on what compounds now and keep an option on what's coming.

Zach Martin

Now the Moon, where the opening story is a quiet one. On December 14, 1972, at the end of Apollo 17, Eugene Cernan drove the Lunar Roving Vehicle to a final position in the Taurus Littrow valley, parked it, and walked away. Space Capital's write up on Lunar Outpost notes that the rovers were never designed to survive. Their silver zinc batteries were single use. Their thermal systems weren't built for the roughly 300 degree swings between lunar day and night. Each supported a mission of about three days and traversed at most 36 kilometers. Across all three missions that used them, the rovers drove about ten hours and covered roughly 90 kilometers, and after Apollo 17, no American vehicle touched the lunar surface for fifty three years.

Zach Martin

Why does that history matter for investors? Because it shows what happens without a commercial framework. The infrastructure problem went unsolved because no commercial model existed to solve it, and legacy cost structures made bespoke, single mission hardware the only thing anyone knew how to build. Lunar Outpost, founded in 2017 by brothers Justin and Julian Cyrus along with Forrest Meyen, is built on the opposite premise. Both brothers started at Lockheed Martin, and Space Capital says they came away believing cost plus contracting rewarded delay and perfection over learning, and couldn't produce the iterative, services oriented infrastructure the next era needs. The company's argument is that mobility is the layer that activates the others. A power station no one can drive to is a stranded asset. A communications relay without endpoints is a tower in the dark.

Zach Martin

Then the milestone. According to the research brief, on May 26, 2026, NASA awarded Lunar Outpost and Astrolab firm fixed price task orders under the $4.6 billion Lunar Terrain Vehicle Services program, or LTVS. Lunar Outpost's task order was $220 million, to build Pegasus, a two astronaut rover that can be autonomous or teleoperated, with a 900 kilometer range and a one year surface life. Compare that to the Apollo vehicle's 36 kilometers and a few days. The company had already taken its MAPP rover systems to technology readiness level nine during the IM two mission, and it's building with partners including GM, Goodyear, and Leidos. I'd note the brief states these figures, and I haven't seen the NASA award documents, so I'd attribute the numbers to Space Capital's account.

Zach Martin

Now see why firm fixed price is the key phrase. Under a firm fixed price contract, the price is set in advance. If the company runs over budget, it eats the cost. If it delivers early and lean, it keeps the upside. That's the opposite of cost plus. And it connects to the broader shift described by NASA Deputy Administrator Matt Anderson, a month into the job at the time, at the same Summit. His line was that we cannot do our job without commercial companies. Space Capital summarizes the new model as the agency being an anchor customer, not the sole builder. Anderson described it as incentivizing excellence. Deliver on cost, schedule, and performance and you get repeat business. Miss, and your contract is canceled and the money redeployed.

Zach Martin

What I like about the NASA story is that it gives the whole lunar sector something rare, a schedule. Space Capital reports hard dates set by national space policy. Artemis III in 2027 is slated to put the three largest rockets in the world, SLS, Starship, and New Glenn, into orbit within days of each other, which Anderson summarized as three rockets, two dockings, and one splashdown. A crewed lunar landing is targeted for 2028. The ISS retires in 2030, with a commercial station as the replacement, where NASA is a major early customer but not the only one. And there's one inconsistency in the sources I should flag. The Lunar Outpost write up describes the Ignition plan as resequencing the first crewed landing under Artemis IV, while the Summit write up describes Artemis III as a low Earth orbit rehearsal for the 2028 landing. Those fit together, but the numbering is easy to confuse, so I'm describing it as the 2028 crewed landing and leaving the mission numbering to NASA.

Zach Martin

Anderson also said something I think investors should take literally. Asked whether NASA prefers public or private companies, he said it's just outcomes, and how you're funded is irrelevant to us. And he conceded that early on, the lunar outpost is going to look like a junkyard. I appreciate that candor. It signals an industrial buildout, not a highlight reel. Water ice at the lunar south pole is the reason for the destination, because propellant produced on the Moon changes the economics of everything beyond it. That's a long game. The early money isn't in mining ice. It's in the vehicles, the power, the communications, and the services that make any later activity possible.

Zach Martin

Now apply my two questions. What does Lunar Outpost sell, repeatedly? The LTVS structure is services, which is the point of the name. A company that builds a rover and then operates it for a customer, with an autonomy stack that coordinates a fleet without continuous ground control, is selling capability by the mission and potentially by the year. Space Capital also says Lunar Outpost has sold thousands of sensor products on Earth, in environmental sensing and mining, which gives it revenue that doesn't depend on a single launch date. That's the kind of diversification I want to see in a deep tech company. And what has to be true? The rover has to work in the lunar environment on the lunar schedule, and NASA has to keep its dates. The first part is engineering. The second part is politics and budgets. Romo's warning about news cycles and budget reports applies here too.

Zach Martin

Let me step back and give you the whole film in one view. SpaceX showed that the public market will pay for a full stack and will let a company use its stock as currency. Rocket Lab and Amazon showed that the scarce asset is what you own once you reach orbit, spectrum in particular. Eclipse is testing whether you can own a constellation without owning a factory. Xona is testing whether a government cancellation can become a commercial service built on a stronger signal. Impulse is testing whether maneuver, paid for by prizes and milestones, can become the next orbital currency. And Muon and Lunar Outpost are testing whether off Earth infrastructure can be priced like a service instead of a spectacle.

Zach Martin

Here's the coaching summary, and I'll keep it simple. One, follow the recurring revenue. Spectrum, positioning and timing, wildfire intelligence, firm fixed price lunar mobility, these are things a customer pays for again and again. Two, respect the unit economics. The orbital data center is eight to ten times too expensive today by Dyer's own estimate, and Golden Dome's interceptors only stay in the program if they're affordable at scale by General Guetlein's own standard. Both of those are builders and operators telling you the cost gate is real. Three, watch for the conversion from demonstration to contract. Demonstrations are warm up. Awards are the game.

Zach Martin

And four, remember that abundant capital is a test, not a trophy. First half 2026 investment of $67.6 billion, a record by Space Capital's count, means more companies will get funded than should. Space Capital's own Chad Anderson has said that in space, as in venture capital, things take longer than expected but happen faster than imagined. His 2025 report card gave himself a B plus, noting that timing on specifics like Starship operations and the Vast station was optimistic. I take that as a model of how to think. Get the big themes right, stay humble on the dates, and keep your eyes on what compounds.

Zach Martin

If you take one habit from today, make it small and repeatable. Pick a company in this sector you care about, and every quarter write down three lines. What did it sell this quarter, and will the customer buy again? What did it spend per unit of what it sells, and is that number falling? And what did it promise last time, and did it deliver? That's it. No genius required. Just the discipline of checking, over and over, until the pattern speaks for itself. Compounding doesn't care about hype. It rewards the ones who keep showing up. Thanks for spending the hour with me. I'm Zach Martin, and this has been SPACE CAPITAL on KMKT IR Hub Radio. Real assets, real ideas, and a brighter tomorrow. See you next time.
