Haven-2

In Development

Vast's proposed successor to the International Space Station and its bid for NASA's CLD Phase 2 competition. Modules launch on Falcon Heavy roughly every six months starting in 2028, building from a single NASA-certifiable 16 m module to a nine-module station by 2032 with 12 crew, a 3.8 m cupola, EVA airlock, external payload facilities, and Starlink laser terminals. Unlike Haven-1's 160 crew-days of consumables, each Haven-2 module supports 720 crew-days and cargo resupply.

    NASA CLD Phase 2 award decision (Haven-2 bid)

    NASA released the draft RFP on July 6, 2026, and the industry feedback window closed July 27. The late-August final-RFP window then slipped: on September 4, 2026 NASA Johnson posted a CLDC presolicitation saying the formal RFP is now anticipated at the end of September 2026, with offers due 60 days after release (roughly late November) and industry questions due September 15. A contract selection is still expected in early 2027 per rival bidder Voyager Technologies' August 3 earnings call. Vast's Haven-2 roadmap (first module 2028) hinges on selection.
