Abstract
LUMIO is a 12U CubeSat destined for a halo orbit around the Earth-Moon L2 point, requiring 203 m/s of delta V for orbital transfer, station-keeping and disposal manoeuvres, to be delivered by its Main Propulsion System (MPS). A total impulse of 170 N-s is required to be delivered by its Reaction Control System (RCS) for de-tumbling and reaction wheel de-saturation. A custom propulsion system was designed including commercial-off-the-shelf thrusters, valves, filters, sensors and a micro-gear pump to fulfil these functions. The pump-fed MPS uses 'green' mono-propellant LMP-103s and the RCS uses water propellant, with a resulting wet mass of 5.563 kg for the MPS and 0.822 kg for the RCS.
