## Key Points

- Axiom Space filed a lawsuit against Vast Space in Houston federal court under the False Claims Act, seeking treble damages
- At the center of the dispute is the MIOMP document, which Axiom considers a copy of its work, while Vast explains it as a receipt from a common subcontractor
- Vast claims it notified NASA of the error within 24 hours and submitted a corrected version the next day
- The legal process coincides with NASA's commercial orbital station competition, with final proposals due December 14, 2026

On November 13, 2026, the Federal Court in Houston registered a lawsuit by Axiom Space against California-based Vast Space, filed under the U.S. False Claims Act, which provides for civil liability for fraud against a government client. Axiom claims that Vast submitted a Mission Integration and Operations Management Plan (MIOMP) to NASA — a detailed operational plan for a manned mission describing every stage of flight from launch to crew return — which, according to the plaintiff, contained Axiom's own long-term proprietary data. The company is seeking civil penalties, treble damages, and reimbursement of legal fees. Axiom alleges that in several places, Vast replaced the company name with a generalized phrase "private manned mission provider" but kept Axiom’s corporate data in other sections, which, in the plaintiff’s view, proves copying rather than independent development of the document.

### Vast's version: subcontractor and standard documentation

Vast Space categorically rejects the accusations. In an official statement, the company explained that it received the MIOMP from a subcontractor who provides services to both Axiom and Vast, and the document was based on standard documentation from previous program missions. According to Vast, the received file did indeed contain materials from one of Axiom’s past missions, but the company asserts that it independently notified NASA of the need for correction within 24 hours of submission and provided an updated version the very next day. Vast also emphasizes that cooperation with NASA on its sixth private manned mission continues without delays. The U.S. Department of Justice declined to intervene in the proceedings, which does not, however, mean that the accusations have been refuted: Axiom is pursuing the case independently.

### Context: Private Astronaut Missions program and the landscape

The conflict is unfolding at a critical moment for both companies. NASA has been developing the Private Astronaut Missions program since 2019, allowing commercial operators to organize flights for private crews of up to four people to the International Space Station. Axiom was the first to receive contracts for four such missions: the first took place in April 2022, and the fourth in the summer of 2025. In January 2026, NASA selected Axiom for the fifth mission, in February Vast received the sixth, and in April Voyager Technologies received the seventh. Thus, both companies are currently executing contracts within the same program simultaneously, which makes any accusations of operational document copying especially sensitive for their reputations and competitive positions.

### The lawsuit against the backdrop of the commercial space station competition

The situation is made more acute by the fact that the proceedings are beginning immediately before the next stage of NASA’s competition for creating commercial orbital stations. Final proposals from applicants must be submitted by December 14, 2026. Among the participants, besides Axiom and Vast, are Voyager Technologies, Blue Origin, and possibly SpaceX. NASA has confirmed that it is aware of the legal dispute but declined to comment on its details. The allegation of document copying in itself does not mean disqualification of Vast from the competition, but proven fraud while working with a government client could significantly complicate the company’s participation in future agency contracts. For Axiom, in turn, success in court would demonstrate the protection of intellectual property accumulated over years of organizing manned flights and strengthen its position in the upcoming selection of orbital station operators.

### What's next: the process and possible consequences

The lawsuit in Houston will likely drag on for months, as the False Claims Act involves a complex mechanism of proof, including analyzing the document’s chain of custody, the role of the subcontractor, and the timing of when NASA might have been misled. A key question will be whether the MIOMP was developed by Vast from scratch based on standard templates or effectively replicates Axiom’s unique operational procedures. The answer to this question will determine not only the outcome of the current lawsuit but also whether Vast can participate without restrictions in the competition for commercial orbital stations, the results of which NASA plans to summarize in the first half of 2027.

## Accounts differ

### Origin of the MIOMP document submitted by Vast to NASA

- **Axiom Space:** Vast copied the operational plan from Axiom's materials, replacing the company name with a generalized term in some sections while leaving Axiom's corporate data in others, proving copying rather than independent development ([ixbt.com](https://www.ixbt.com/news/2026/11/13/sudebnaia-tiazba-dvux-konkurentov-axiom-obvinila-vast-space-v-kopirovanii-planov-pilotiruemyx-missii-dlia-nasa.html))
- **Vast Space:** The document was obtained from a subcontractor who provides services to both companies and was based on standard documentation of previous missions; Vast independently notified NASA of the correction within 24 hours and submitted a new version the next day ([ixbt.com](https://www.ixbt.com/news/2026/11/13/sudebnaia-tiazba-dvux-konkurentov-axiom-obvinila-vast-space-v-kopirovanii-planov-pilotiruemyx-missii-dlia-nasa.html))

*Where they agree:* The document submitted to NASA did contain Axiom materials and corporate data; both parties acknowledge the fact that these data were in the file

## FAQ

### What is MIOMP and why is it important?

Mission Integration and Operations Management Plan is a detailed operational plan for a manned mission describing all flight stages from launch to crew return. For NASA, accepting this plan is a prerequisite for the next contract payment, and for the operator, the document confirms the ability to safely organize a flight.

### What does Axiom demand from Vast Space?

Axiom is seeking civil penalties, treble damages, and reimbursement of legal fees. The lawsuit is filed under the False Claims Act, which provides for liability for fraud against a government client.

### How does Vast Space explain the presence of Axiom's data in the document?

Vast claims it received the MIOMP from a subcontractor who serves both companies, and it was based on standard documentation for previous missions. The company states it informed NASA of the need for correction within 24 hours and submitted a new version the next day.

### Will the lawsuit affect Vast's participation in the commercial orbital station competition?

The accusation itself does not mean automatic disqualification. However, proven fraud while working with a government client could complicate Vast's participation in future NASA contracts. Final proposals for the orbital station competition are due December 14, 2026.
