Key highlights
The Astra Spacecraft Engine (ASE) Max is a kilowatt-class propulsion system using krypton or xenon propellant. The thruster is suitable for missions requiring high total impulse per thruster.
ASE Max is ideal for communication satellite constellations, for small GEO spacecraft, and as an enabling technology for high throughput LEO, GTO-GEO transfer, and cislunar missions.
ASE Max includes a magnetically shielded thruster which is tuned to optimize performance with krypton propellant. The thruster is matched to an Astra radiation-hardened, 95% efficient, single-board PPU, a propellant management system with flight heritage components, and a COPV tank sized to fit customer mission requirements.
ASE Max has been selected for programs such as a GEO mission and a commercial constellation with several hundred satellites.
Key features
- Tuned to optimize performance for krypton propellant
- Designed for use with krypton or xenon propellants
- Magnetic shielding for at least 1.5 MN-s total impulse
- Consistent performance from the start of life to the end of the mission
- Instant-start, center-mounted cathode
- Designed for multi-thruster operation
- Thruster can operate between 800 W and 1.8 kW to PPU (System optimized for 1.4 kW operation)
