NIAC Award: High Irradiance Peltier Operated Tungsten Exo-Reflector

Concept of the HI-POWER rover. A small vehicle is shielded from the sun with a tungsten shield. The connections to the shield are comprised of stacked POLAR coolers. The outer skirt of the shield includes arrays of thermoelectric generators which absorb heat from the shield and radiate waste heat to the ground without heating the rover. (Credits: Troy Howe)

One issue that arises with spacecraft in almost every mission is thermal management. Computers, instruments, and housing may heat up in space, as a combination of solar energy and poor heat rejection causes temperatures to rise to hundreds of degrees. This can be fought by advanced radiators or may require specialized cooling systems.

Nuclear electric propulsion (NEP) systems have the potential to provide a very effective transit mechanism to celestial bodies outside of the realm of solar power, yet the heavy power source and massive radiators required to justify a reactor core often push NEP spacecraft towards very large masses and major missions.
