Haven-1's thermal control system is integrated and its in-house Hall thruster begins vacuum testing

Vast/Haven-1

Vast integrated Haven-1's thermal control system in June 2026 and began vacuum-chamber testing of its in-house electric Hall thruster, which uses electric fields to accelerate charged gas for thrust. The commercial space station was targeted to launch in early 2027.

• Thermal control system integrated; uses additively manufactured cold plates for direct avionics heat rejection
• Hall thruster: in-house designed electric propulsion using electric fields to accelerate charged gas
• Vacuum-chamber testing validates thruster performance for space operations
• Haven-1 launch targeted for Q1 2027; multi-module Haven-2 successor envisioned as ISS successor
