Haven-1

In Development

A single-module commercial space station scheduled to become the world's first, launching complete on a SpaceX Falcon 9 to a 425 km, 51.6° orbit. It hosts four astronauts for roughly two-week Dragon missions, with private crew quarters, a 1.1 m domed window, Starlink laser connectivity, and the Haven-1 Lab microgravity research facility. The flight structure has passed beyond-nominal pressure testing and is in final integration for launch readiness in Q1 2027, followed by an uncrewed Dragon docking verification before the first crew.

Announced next steps from Vast that mention Haven-1.

  1. Late 2026

    Complete Haven-1 integration and environmental testing

    Vast says it will finish all three integration phases (fluids/life support, avionics/GNC, crew interior and MMOD shielding) plus a suite of environmental tests at NASA's Neil Armstrong Test Facility (former Plum Brook Station, Ohio) in 2026. As of early September 2026 Vast's site still shows flight solar arrays in acceptance inspection and the Vast Control Unit in EMC testing; no shipment of the flight vehicle to Ohio has been announced, so the environmental test campaign has not yet started. Watch for phase-completion updates and the shipment to Ohio - the last major gates before launch.

  2. Q1 2027

    Haven-1 launch on Falcon 9

    Launch readiness for the world's first commercial space station remains set for Q1 2027, already re-baselined from August 2025 and then 2026. Vast's Haven-1 page still lists the station as launching in 2027. As of early September 2026 Vast is still completing integration and has not yet started the environmental test campaign at NASA's Neil Armstrong Test Facility. Watch for a firm launch date and the uncrewed Dragon docking verification that must follow before any crew flies.

  3. 2027

    Vast-1: first crewed mission to Haven-1

    Four astronauts, including French ESA reserve astronaut Arnaud Prost as flight test engineer, would arrive within weeks of launch on a SpaceX Dragon for a roughly two-week stay - but timing depends on SpaceX verifying Haven-1 is safe for Dragon docking, which CEO Max Haot has said could take from two weeks to much longer. Watch crew announcements and docking-verification progress.

  1. Vast starts Lunar Programs division for NASA Moon Base work

    Vast announced on September 23 that it has created a Lunar Programs division to pursue NASA Moon Base work using Haven-1 heritage, with Haven-1 still in final integration in Long Beach for a targeted 2027 launch. Planned offerings start with a solar power station, then a Haven-derived lunar airlock and later a multi-module habitat, plus a proposed South Pole communications and positioning constellation. Founding team member Colin Smith is senior vice president of Lunar Programs. Independent coverage treated the move as a bid for NASA lunar contracts, not an award.

  2. Vast launches national security division, hires ex-Slingshot CEO

    Space station developer Vast said on July 22 it has established a new Special Programs division to pursue space work for the US defense and intelligence communities, naming Melanie Stricklan, the former CEO of space-domain-awareness company Slingshot Aerospace and a 21-year Air Force veteran, as senior vice president to lead it. The division will draw on Vast's commercial Haven station and satellite-bus platforms and manufacturing base to deliver classified and unclassified systems, adding a national-security revenue line alongside Haven-1, which is in final integration ahead of a targeted Q1 2027 launch.
