AIM spacecraft Facts & Figures
The baseline propulsion system for the AIM spacecraft will use a bi-propellant (MMH/MON) fuel with 24 thrusters, each capable of producing 10 N of thrust.
A separate Helium tank would keep the four 60 L propellant tanks pressurized. Power is generated by two deployable, fixed solar arrays with an output of 165 W each at a distance of 2.2 AU from the Sun, and a total panel surface of 5.6 m². The total spacecraft dry mass would be about 420 kg and the propellant mass about 292 kg.
