For over 50 years, hydrazine has been the industry standard for monopropellant propulsion systems, widely used in satellite attitude and orbit control systems. However, hydrazine’s toxicity necessitates expensive handling procedures and may lead to a future ban of the propellant in Europe. This has motivated the development of novel...

This research describes a near-optimal feedback guidance, based on nonlinear orbit control, for low-thrust Earth orbit transfers. Lyapunov stability theory leads to proving that although several equilibria exist, only the desired operational conditions are associated with a stable equilibrium. This ensures quasi-global asymptotic convergence...

The use of additive manufacturing (AM) can potentially offer significant benefits to the design and performance of resistojet components but has so far only seen limited research in this application. The goal of this study was to investigate the possibility of 3D printing a functional resistojet heating chamber and the potential benefits that...

High concentration hydrogen peroxide (HP) promises to be an economical and green alternative for hydrazine. However, it has only limited storage life, and addition of stabilizers must be avoided to preserve the high purity required for propellants. This work has investigated the mechanical fastening of normally dissolved stabilizers on the...

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...

Current research trends have advanced the use of “green propellants” on a wide scale for spacecraft in various space missions; mainly for environmental sustainability and safety concerns. Small satellites, particularly micro and nanosatellites, evolved from passive planetary-orbiting to being able to perform active orbital operations that may...
