The collaboration bolsters Vast’s role within NASA’s private astronaut mission (PAM) ecosystem and highlights its commitment to the future of space-based science and commercial development in low-Earth orbit.
Awarded by CASIS, the agreement acknowledges Vast’s innovative spacecraft platforms and its commercial-first approach to extending human presence in orbit. The partnership is designed to open new pathways for in-orbit servicing, while broadening ISS access to emerging players in space research.
Through this collaboration, Vast will support scientific and technical projects that align with future NASA PAM initiatives, particularly those involving astronauts and international space agencies planning missions aboard the ISS. This agreement also enables Vast to test its technology in microgravity conditions—an essential milestone as it moves closer to developing an ISS successor under NASA’s Commercial LEO Development Program.
“This agreement gives Vast direct access to the ISS—a critical step as we prepare our NASA Private Astronaut Mission bid,” said Max Haot, CEO of Vast. “It enables us to fly science, validate our technologies in microgravity, and continue our close collaboration with NASA, all of which are crucial as we design our proposed ISS replacement.”
Vast and CASIS share a unified vision of fostering greater commercial and international use of space as a frontier for research and innovation. Their partnership is expected to accelerate breakthroughs that benefit both life in orbit and advancements here on Earth.
“The ISS National Lab plays a vital role in expanding access and opportunities for research and technology development in space,” said Ray Lugo, CEO of CASIS. “We’re thrilled to work with Vast as they strive to expand innovation and participation beyond Earth’s horizon.”
Vast reaffirmed its ambitions in 2024 by announcing plans to participate in future NASA private astronaut missions. That same year, the company secured two SpaceX Dragon flights to the ISS, laying the groundwork for its upcoming PAM proposals and solidifying its role in the evolving landscape of commercial spaceflight.
