​​Thermasat is a propulsion system for Cubesats that uses water as a propellant. The propellant is heated to high temperature steam through optical manipulation of incident sunlight. The optical system uses nano-structures known as photonic crystals to limit infrared emission.  The propulsion system provides deployment, station keeping, and end of life de-orbit. Can provide propulsion for a 15kg Cubesat for a 10 year lifetime.

ThermaSat V2.0

Recent changes in design now allow for more photovoltaic augmentation and a compact 2U form factor. This new design still provides all the propulsion needs for satellites up to 10 kg.
