Astra Space

Astra Space is an American aerospace manufacturer focused on providing dedicated orbital launch services and electric propulsion systems for the small satellite market. Positioned as a vertically integrated provider, the company designs and builds its own launch vehicles and spacecraft components in-house, aiming to lower the barriers to space access through mass-produced hardware and portable launch infrastructure. The company is best known for the development of its Rocket 3 and Rocket 4 launch vehicle series, having conducted orbital missions from facilities in Alaska and Florida. Beyond launch, its propulsion division supplies the Astra Spacecraft Engine, an electric Hall-effect thruster designed for satellite constellation deployment and station-keeping. Customers include commercial satellite operators and government agencies, including contracts associated with NASA and the United States Space Force. Prospective partners should verify the current operational status of the Rocket 4 development programme and the company's recent shift in strategic focus towards its spacecraft engine business. It is also necessary to confirm the specific flight heritage of propulsion units relative to the buyer's intended orbital environment and mission duration requirements.
