Custom 1 Prop

ASE (Astra Spacecraft Engine) & ASE MAX can be configured with multiple thrusters and PPUs to handle a wide range of missions, from the smallest Earth observation satellites with 100W Orbit Average Power, up to large communication satellites with multiple kilowatts of solar power. With multiple thrusters, LEO-GEO orbit raises can take as few as 12 weeks.

INTEGRATED PROPULSION SYSTEMS BUILT FOR YOUR SPACECRAFT

COMPACT
THRUSTERS

ASE and ASE Max include an instant-start center-mounted cathode and compact design. Each thruster leverages the past 50 years of Hall thruster research in an efficient, clean sheet design.

RAD HARDENED POWER PROCESSING

The PPU (Power Processing Unit) is radiation hardened by design, replacing many microprocessors with simple and reliable components – creating a single circuit board design that is 95% efficient.

FEED SYSTEMS WITH HERITAGE

Single and multi-thruster configurations include gaseous feed systems with flight-proven components from respected industry partners with flight heritage.

FLIGHT-PROVEN COPV PROPELLANT TANKS

Propellant tanks are sized specifically to fit the unique requirements of each customer mission with flight-proven COPV construction rated to 2,700 psi or 4,000 psi.
