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.
