Even though some miniaturized systems that could fit in a CubeSat framework have been developed, chemical propellant systems ...

These miniature engines are ideal for small satellites called CubeSats that are often used in academic research. Since electrospray engines utilize propellant more efficiently than the powerful ...

While prototypes of water-powered rocket thrusters and engines have been developed before, and a few have succeeded in launching CubeSats, water has not yet been used as a propellant on a large scale.

A fully assembled system is expected to weigh 25 kg "Dry"—meaning without propellant installed ... bus was also the fuel tank, and it had additional slots for CubeSat components.
