About
Vast is a commercial space station company founded in 2021 by Jed McCaleb, the entrepreneur behind Ripple and Stellar, with a mission to build privately owned and operated habitats in low Earth orbit. As NASA's International Space Station approaches decommissioning, Vast is positioned to provide a successor commercial destination for astronauts, researchers, and private space travelers. The company is building a family of modular space stations designed to serve as research platforms, manufacturing facilities, and eventually long-duration human habitation in orbit — the next phase of human spaceflight infrastructure.\n\nVast's initial product is Haven-1, a single-module commercial space station designed for short-duration crew missions. Haven-1 is scheduled for a crewed launch in May 2026 aboard a SpaceX Crew Dragon, making it the first commercial space station to host astronauts. A demonstration version of the Haven module completed a three-month uncrewed orbital mission between 2025 and 2026, validating the platform's life support, power, and structural systems in orbit. Vast is also developing Haven-2, a larger multi-module station intended for longer-duration research and commercial operations.\n\nVast raised $500M in March 2026, bringing total capitalization to over $500M and enabling the company to accelerate station development and expand its mission manifest. The company has partnered with SpaceX for launch and crew transportation services. Vast is competing with Axiom Space and Blue Origin's Orbital Reef project for the commercial space station market, which NASA is funding through its Commercial Low Earth Orbit Destinations (CLD) program as a deliberate strategy to transition human spaceflight from government-owned to commercially operated infrastructure.
Relativity Space is building the world's first fully 3D-printed rocket, using autonomous robotic manufacturing to reduce production time from years to 60 days. HQ: Long Beach, CA.
About
Relativity Space is an aerospace company pioneering a new approach to rocket manufacturing through large-scale 3D printing and autonomous robotics, with the goal of building a fully vertically integrated launch company that can design, manufacture, and launch rockets at a fraction of traditional cost and time. Founded in 2015 by Tim Ellis and Jordan Noone, former SpaceX and Blue Origin engineers, Relativity uses its proprietary Stargate metal 3D printing system — the world's largest metal 3D printer — to fabricate rocket structures from aluminum alloy, reducing part counts from 100,000+ (traditional rockets) to under 1,000.
