MUSIC Electric Propulsion System
Multi-stage Hall thruster
Multi-mode operation
Instant ignition option possible
Modular design
High thrust-to-power ratio

MUSIC Electric Propulsion System offers a modular architecture that allows for the widest dynamic range of thrust and specific impulse for such a system available on the market today. With three modes of operation, MUSIC can provide a thrust raging from as low as 0.1 mN to as high as 3 mN, with a total impulse up to 15 kNs within a 4U form factor.

The self-ignition mode provides unprecedented low-power consumption and instant ignition (without "hot stand-by") for a Hall thruster. Aliena deployed the record-breaking technology on a 3U nanosatellite in January 2022

 

Our low-current hollow cathode technology allows for reliable high thrust/high specific impulse operation at sub-100 W in hot mode. MUSIC-HM was deployed in space on a 12U satellite in July 2023

 

The dual mode operation, which integrates both the self-ignition technology and the hollow cathode, makes MUSIC the Hall thruster with the widest dynamic thrust range and a fault tolerant system that can ignite on demand.        â€‹
