DESIGNED, MANUFACTURED, & TESTED FOR MAXIMUM RELIABILITY
The Astra Spacecraft Engine™️ (ASE) & Astra Spacecraft Engine Max (ASE Max) can be configured with multiple thrusters and PPUs to handle a wide range of missions, from the smallest earth observation satellites up to large communications satellites with multiple kilowatts of solar power.
Each system is delivered fully integrated and tested to reduce spacecraft development complexity, while improving on orbit reliability.

Instant-start, heaterless, center-mounted cathode and permanent magnet design deliver high thrust and high Isp in a compact design which has been ground tested to 12,000 operational cycles.
RADIATION HARDENED POWER PROCESSING UNIT
The Power Processing Unit (PPU) is radiation hardened by design, replacing many microprocessors with simple and reliable components – creating a single circuit board design that is 95% efficient.
Increased radiation hardening extends system lifetimes and supports a broad range of LEO and GEO missions.
FEED SYSTEM WITH HERITAGE
Compact, bang-bang feed system with flight-proven components.
Each system is leak and vibration tested in an integrated system test to ensure on orbit reliability.
FLIGHT-PROVEN PROPELLANT TANK
Flight-proven, off-the-shelf propellant tanks meet a broad range of mission requirements without the high cost or long lead times of custom tanks.
Tanks are sized specifically to fit the unique requirements of each customer mission with flight-proven COPV construction rated to 4,000 psi.
MEETING MISSION DEMANDS WITH
MULTI-THRUSTER ASE CONFIGURATIONS
Need to go faster? Need to go farther? Need to do both? Multi-thruster ASE configurations allow you to build a system that meets your unique mission requirements. Select the number of thrusters that meet your delta-v requirement and choose a tank that meets your total impulse needs to build the best configuration for your constellation.
