NASA Future In-Space Operations: SmallSat Thrusters

NASA FISO Presentation: The Film Evaporation MEMS Tunable Water Microthruster Array

"Miniaturization of satellite systems provides potential for reduced launch and operations costs
- Small sats i.e. micro, pico, nanosats are emerging technologies.
- Cubesats (4 inches cube) are low cost alternative for some applications.

Propulsion systems resist miniaturization
- Viscous losses at small scale
- Low mass fraction due to power processing mass
- Excessive power demands for small sat applications"
