Astra Space
Develops small-lift launch vehicles with mobile launch infrastructure and manufactures Hall-effect electric propulsion systems for satellite constellations
Astra Space designs and manufactures small-lift launch vehicles and electric propulsion systems for satellites. Its primary launch product, Rocket 4.0, is a two-stage expendable vehicle targeting one tonne to low Earth orbit, paired with a containerized mobile launch system deployable to austere locations.
The company's spacecraft engine division produces Hall-effect thrusters compatible with xenon and krypton propellants. Astra has shipped over 110 satellite engine systems and holds contracts with constellation operators and defense customers. Launch sites include the Pacific Spaceport Complex in Kodiak, Alaska and Cape Canaveral, Florida. Astra holds contracts with the U.S. Space Force and the Defense Innovation Unit. Founded in 2016, the company went public on NASDAQ in 2021 and returned to private ownership in July 2024. Headquarters and manufacturing are in Alameda, California.
