Astra Spacecraft Engine
Electric thrusters that satellites use to maneuver and hold their orbit, sold to other satellite makers.
Why it matters
Every satellite needs to move once in orbit. Electric propulsion uses far less propellant than chemical thrusters, which lets satellites last longer or carry more.
How the technology works
The engine is an electric thruster with a magnetically shielded design and a center-mounted cathode. It runs on xenon or krypton and uses power from the satellite's solar panels to produce small, steady thrust.
