NASA says the commercial market for low Earth orbit doesn't exist. Axiom Space has a different view of the evidence: 12 paying customers, 166 payloads flown, and $2.2 billion in signed contracts. Three companies showed up at the 41st Space Symposium in Colorado Springs last week with those numbers and a direct challenge to NASA's Ignition event — the agency had proposed, just three weeks earlier, that commercial demand has not materialized and floated a new approach to the Commercial LEO Destinations program that would reshape the entire transition away from the International Space Station.
NASA issued a formal request for information the next day, asking companies to show their work. The companies showed up.
"We put in 390 pages of independent analysis, research studies, data, contracts," said Marshall Smith, chief executive of Starlab Space. He also cited at least $3 billion in private capital invested in companies working on commercial stations — what he called a signal from the market that NASA was declining to read.
Jonathan Cirtain, CEO of Axiom Space, pointed to what he said is the most direct evidence: his company's own revenue history. "We've flown 12 people to space who paid us money to do that," he said. "We've flown 166 payloads to date. All of those are paying payloads that generate revenue." Axiom has conducted four private astronaut missions to the ISS, with a fifth planned no earlier than January 2027, and carries $2.2 billion in customer contracts, according to the company's most recent disclosures. The customers Cirtain is counting on for growth are not space tourists — they are sovereign nations and national space agencies, which he argues represents a durable government demand signal that NASA itself helped create through the Artemis program.
Max Haot, CEO of Vast, made the most specific profitability claim of the three: he says Vast can operate at positive margin on NASA contracts alone, without any revenue from in-space manufacturing, sponsorships, or tourism. His model assumes winning 40 to 60 percent of the total CLD development money from NASA and securing one six-month NASA mission per year, plus a shorter 30-day mission from another nation. "With that alone, and with zero dollars from in-space manufacturing, sponsorship and tourism, Vast can be profitable," Haot said.
The companies are not, however, claiming the market is mature. Haot specifically acknowledged the view expressed by NASA Administrator Jared Isaacman and his team that current private demand is "not substantially large enough" to sustain a commercial station on its own. The argument is about what happens next — and specifically, who controls what comes after the ISS.
That is where the structural contradiction lives. NASA's own FY2027 budget proposal, which covers spending projections through 2031, includes more than $1.5 billion for the CLD program in 2031 — with $1 billion of that redirected from current ISS operations. That transfer only makes sense if commercial stations exist. But the agency's policy position is that the commercial market has not yet demonstrated it can support them. Representative George Whitesides of California, a former NASA chief of staff and former CEO of Virgin Galactic, named the problem directly at a March 25 House Science Committee hearing: "I just don't see how it's fiscally possible for NASA to afford the development and launch of a custom-built government core module, while maintaining ISS, while claiming at the same time it can't afford to be a customer on a commercial station that is being privately financed."
NASA's proposed solution — a government-procured core module that commercial stations would dock to before eventually detaching as free-flying platforms — is designed to reduce the risk of a gap in U.S. human presence in LEO. Agency officials argue the current approach leads to a single CLD provider, which they consider too risky given ISS's age and the planned 2030 deorbit. Companies counter that the core module approach eliminates competition entirely and hands the outcome to whichever company builds that module.
The debate is not academic. Haven-1, Vast's first station module, was originally targeting August 2025. It is now scheduled to launch no earlier than Q1 2027. That is not unusual in spacecraft development — it is however a reminder that every company in this space is building against a hard deadline imposed by the ISS retirement, with investors, customers, and NASA all watching the same clock.
Dave Cavossa, president of the Commercial Space Federation, offered a blunt summary at the same hearing: "My concern is that if NASA is not a reliable partner for private investors, we're not going to get that money and we're not going to save them money by being able to cost-share with the private sector." The $3 billion in private capital that has gone into the sector suggests some investors are willing to bet on the outcome anyway. The question the RFI responses are meant to answer is whether that bet has a financial model underneath it — or whether it is still a bet on NASA eventually agreeing with the premise.
