Astra Space develops small-lift orbital launch vehicles and electric propulsion systems for satellites. The company operates a two-pronged business: launch services for small satellites via the Rocket 3 and Rocket 4 platforms, and in-space propulsion engines acquired from Apollo Fusion (Hall-effect thrusters for station-keeping, collision avoidance, and de-orbiting). Founded by Chris Kemp (former NASA CTO) and Adam London, Astra evolved from Ventions LLC (2005), initially focused on miniaturized propulsion before pivoting in 2017 to full small-launch vehicles. Originally went public via SPAC (Holicity) at $2.1B valuation in July 2021 but delisted after founder buyout at $0.50/share in July 2024.
