COLORADO SPRINGS—Aspiring space station operator Vast has signed three international customers to fly payload facilities aboard its planned Haven-1 orbital outpost, the company said April 8.
The new clients are:
• Japan Manned Space Systems Corp. (JAMSS), which has operated Japan’s Kibo laboratory aboard the International Space Station. JAMSS plans to develop a multi-purpose payload facility for microgravity experiments and small payload modules, including devices for colloidal photonic crystallization and interfaces for commercial merchandise items.
• Interstellar Lab, a France-based company developing autonomous AI-powered greenhouse systems. It plans to develop Eden 1.0, a fully automated, controlled-environment greenhouse. The goal is to measure and understand the impact of microgravity on plant growth, including nutrient dynamics, phenotyping and genetic adaptation.
• Exobiosphere, a Luxembourg-based space biotechnology company that develops high-throughput screening platforms to accelerate drug discovery and streamline pre-clinical trial testing. Exobiosphere plans to fly its Orbital High Throughput Drug Screening Device to conduct experiments to accelerate cell growth and uncover cellular behaviors not observable under Earth’s gravity.
The companies’ facilities are scheduled to launch inside Haven-1 in May 2026. Vast has previous agreements with Redwire and Yuri to develop payloads.
“These partnerships reflect a growing global recognition that microgravity is not just a research environment, but a catalyst for transformative breakthroughs,” Vast CEO Max Haot said in a statement.
