Vast Space Selected by NASA for Sixth Private Astronaut Mission to ISS

NASA has officially selected Vast Space to conduct the sixth private astronaut mission (PAM-6) to the International Space Station (ISS). The mission, targeted for launch no earlier than summer 2027, marks a significant expansion in the commercial landscape of Low Earth Orbit (LEO). According to the announcement from the Long Beach-based aerospace company, this selection positions Vast as a key player in NASA’s strategy to transition from government-led operations to a commercial space economy.

The mission will utilize a SpaceX Falcon 9 rocket and a Dragon spacecraft to transport four private astronauts to the orbiting laboratory. While the specific crew members have not yet been named, Vast confirmed that the mission will focus heavily on science and research, distinguishing it from purely tourism-focused endeavors. This contract award represents a major milestone for Vast, which was founded in 2021 and is simultaneously developing its own commercial space station, Haven-1.

Mission Profile and Objectives

Under the terms of the agreement, the PAM-6 mission is designed to spend up to 14 days docked at the ISS. Vast stated in their press release that the primary objective is to conduct a broad range of experiments, including biology, biotechnology, physical sciences, and human research. This focus aligns with NASA’s requirement that private missions contribute to the utilization of the ISS’s research capabilities.

Vast will be responsible for the end-to-end mission management, including crew selection, training, and mission execution, subject to rigorous approval by NASA and its international partners. The company emphasized that this operational experience is critical for their long-term goals.

“Leveraging the remaining life of the International Space Station with science and research-led commercial crewed missions is a critical part of the transition to commercial space stations and fully unlocking the orbital economy.”

Operational Timeline

The summer 2027 target date places PAM-6 in a busy operational window for the company. According to company timelines, Vast intends to launch its own single-module space station, Haven-1, in the first quarter of 2027. If these schedules hold, Vast could be managing two separate human spaceflight programs, one to the ISS and one to its own outpost, within the same calendar year.

Strategic Context: The Road to Haven

Vast views the PAM-6 mission as more than just a flight to the ISS; it is an operational pathfinder for their future independent stations. By managing a crewed mission to the ISS, the company aims to refine the logistics, training protocols, and safety procedures required to operate Haven-1 and its planned successor, Haven-2.

According to industry data, Vast successfully launched a “Haven Demo” pathfinder spacecraft in November 2025 aboard a SpaceX rideshare mission. That demonstration validated critical subsystems such as avionics and propulsion, likely contributing to NASA’s confidence in awarding the PAM-6 contract.

Dana Weigel, NASA’s ISS Program Manager, highlighted the agency’s goal of fostering a robust commercial market through these missions.

“By hosting private astronaut missions, the station helps accelerate innovation, opens new commercial pathways, and advances research strengthening the foundation of a thriving space economy.”

AirPro News analysis

The selection of Vast for PAM-6 signals a notable shift in the private astronaut market, which has previously been dominated by Axiom Space. Axiom operated the first four private missions to the ISS (Ax-1 through Ax-4) and holds the contract for Ax-5. By selecting a second provider, NASA appears to be actively encouraging competition and reducing reliance on a single vendor for commercial access to the station.

Furthermore, this “dual-track” strategy, where Vast pursues both ISS missions and its own station simultaneously, is aggressive. It suggests that the company is positioning itself not just as a participant in the current ISS program, but as a leading contender for the Commercial LEO Destinations (CLD) program that will eventually replace the ISS around 2030.

Frequently Asked Questions

When will the mission launch?
The mission is targeted for launch no earlier than summer 2027.

Who will be on board?
Vast will select four crew members. Their names have not been announced, but they will undergo NASA and international partner approval.

What spacecraft will be used?
The mission will use a SpaceX Dragon spacecraft launched atop a Falcon 9 rocket.

How does this relate to Haven-1?
Vast plans to launch its own station, Haven-1, in early 2027. The ISS mission (PAM-6) serves as an operational experience builder and risk-reduction exercise for the company’s long-term habitation goals.
