Key Takeaways:

Vast Space secured a strategic agreement with CASIS (ISS National Lab) for direct access to the ISS, enabling them to validate technologies, conduct research, and compete for NASA's private astronaut missions as they develop their proposed ISS replacement, Haven-2.
The company also announced three new payload partners—JAMSS, Interstellar Lab, and Exobiosphere—for its Haven-1 Lab, which is nearing full capacity and will host diverse microgravity experiments in biotechnology, pharmaceuticals, and plant growth.

Vast Space, one of several commercial firms vying to replace the International Space Station (ISS) following its planned deorbit at the end of the decade, this week signed key agreements that heighten the competition.

At the 40th Space Symposium in Colorado, where Vast’s Haven-1 space station was on display, the company secured deals that give it direct ISS access and three new customers for its Haven-1 Lab, which is being developed as the first microgravity research and manufacturing platform on a commercial space station. The company is also developing Haven-2, its proposed ISS replacement.
