Vast Space has announced a significant milestone in its pursuit of a commercially operated orbital platform, revealing plans to train up to four astronauts aboard the International Space Station in summer 2027 via SpaceX transportation. The training initiative represents a critical step toward establishing operational capabilities for the company's Haven-1 station, which is targeted for launch in 2027 with full permanent habitability expected by 2030.
The company has already demonstrated technical execution by successfully launching its Haven Demo satellite, positioning Vast as the sole operational commercial space station entity to have deployed its own crewed spacecraft to date. This operational achievement distinguishes Vast from competitors in the emerging commercial space infrastructure sector and validates its engineering and launch capabilities.
Vast's timeline aligns strategically with the anticipated retirement of the International Space Station around 2030, a transition point that creates demand for alternative orbital platforms for scientific research, manufacturing, and other microgravity applications. The company's structured approach—combining workforce preparation, hardware deployment, and operational readiness—suggests institutional confidence in meeting its development schedule during a period of expanding commercial space activity.
