Astra

Astra is a private United States space company that offers launch services and satellite engines. Its website says its mission is to improve life on Earth from space by creating a healthier and more connected planet. The company is headquartered in Alameda, California, and says all its products are designed, built, tested and manufactured in the USA.

Launch services

The launch business centers on Rocket 4.0, a rapidly deployable launch system with orbital flight heritage that Astra describes as mobile and responsive. The site says it can serve mid-inclination low Earth orbit and a wide range of orbital inclinations, with a target launch rate that depends on spaceport availability, and it offers a page on spaceport locations and plans. The company says it offers dedicated orbital launch at one of the lowest costs per launch among operational providers, and that it is the fastest company in history to reach orbit.

Satellite engines

• Electric propulsion systems for satellite constellations, described as flight proven and in use on orbit
• Engines that work with xenon and krypton propellants
• A design using novel magnetic lensing and a magnetic circuit
• Thousands of hours of on-orbit operation

The company reports that it has delivered more than 110 satellite engine systems, a milestone it says shows its scaled production at the Alameda facility.

History

Astra was founded by Chris Kemp and Dr. Adam London, who began designing Rocket 1.0 and its mobile ground support system in a San Francisco garage. Its Orion test facility in Alameda uses a retired jet engine test cell at the former Alameda Naval Air Station as a rocket engine development site. The site also mentions a launch contract from the US Department of Defense.
