The first phase of Haven-1 integration includes installation of the station’s pressurized fluid systems, including thermal control, life support, and propulsion system tubes, and component trays and tanks. These systems will undergo pressure, leak, and functional testing. The second phase of integration will incorporate avionics, guidance, navigation and control systems, and air revitalization hardware. The third and final phase will complete the vehicle with crew habitation and interior closeouts, exterior micrometeoroid and orbital debris (MMOD) shielding, thermal radiator installation, and solar array integration, bringing Haven-1 to a fully flight-ready configuration. Vast remains focused on completing integration and conducting a suite of system environmental tests at NASA’s Neil Armstrong Test Facility later in 2026.
