Vast Space builds artificial gravity space stations to enable long-term human life in space. Its approach uses large rotating habitats that generate centrifugal force to mimic Earth's gravity, helping astronauts stay healthy during extended missions. The company designs, tests, demonstrates, services, and manufactures space infrastructure and customizable habitat modules for government space agencies, private aerospace companies, and research institutions that operate in lunar, Martian, or deep-space missions. Unlike others, Vast Space focuses on end-to-end artificial gravity solutions and ongoing support, not just concepts, and targets contracts that provide sustainable space habitats for science, exploration, and colonization efforts. The overall goal is to expand humanity’s reach across the solar system by creating scalable, gravity-enabled habitats that enable safe, long-term presence in space while protecting Earth's ecosystem.

Simplify's Take

What believers are saying

  • QIA-led $500M funding in March 2026 scales Haven-2 development.
  • Haven Demo succeeded November 2025, validating key subsystems.
  • In-Q-Tel investment signals national security demand for Vast stations.

What critics are saying

  • Falcon 9 capacity constraints delay Haven-1 beyond Q1 2027.
  • Axiom Station captures NASA CLD contract before Haven-2 operationalizes.
  • McCaleb withdraws funding if Ripple faces SEC action by 2027.

What makes VAST unique

  • Haven-1 launches Q1 2027 as first commercial space station on Falcon 9.
  • Haven-1 Lab offers 10 slots for 30kg microgravity research payloads.
  • Roadmap progresses to Haven-2 in 2028 and artificial gravity Haven-3.
  • Six control moment gyroscopes enable precise Haven-1 attitude control.

Vast raises $500M to build commercial space stations with Haven-1 launch in 2027

Vast has raised $500 million in its first significant outside funding, comprising $300 million in Series A equity and $200 million in debt. The round was led by Balerion Space Ventures, with participation from Qatar Investment Authority, IQT, Mitsui, MUFG, Nikon and others. The Long Beach-based company, previously funded by cryptocurrency billionaire founder Jed McCaleb, has invested over $1 billion and employs more than 1,000 people. Vast is building Haven-1, a single-module space station scheduled to launch in early 2027, as a precursor to the multi-module Haven-2 station for NASA's Commercial Low Earth Orbit Destinations programme. The company recently completed testing of Haven Demo, a satellite validating key subsystems, and won a private astronaut mission to the ISS scheduled for mid-2027.
