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.

Development of a space faring civilization will depend on the ability to move cargo efficiently and humans rapidly. Due to the large distances involved in space travel, the ships must reach a high velocity for reasonable mission transit times. Thus, propulsion systems with high specific impulse (Isp) AND high thrust are required.

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.

NASA Supports ‘Wild’ Ideas to Bring About New Space Tech

Swarm-Probe Enabling ATEG Reactor, or SPEAR, is a nuclear electric propulsion spacecraft concept that proposes a new, lightweight reactor moderator and advanced thermoelectric generators to deliver scientific payloads to anywhere in the solar system. SPEAR was selected in April 2019 as a NIAC Phase I. (Credit: Howe Industries LLC)

WASHINGTON, DC (NASA PR) — NASA has a wild side. In fact, the agency has a program dedicated to nurturing visionary ideas that could transform future NASA missions with the creation of breakthroughs—radically better or entirely new aerospace concepts.

For years, NASA Innovative Advanced Concepts (NIAC) has supported early-stage research through multiple phases of study, competitively selecting Phase I and follow-on Phase II projects each year.

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. If the total mass of an NEP system could be reduced to levels that were able to be launched on smaller vehicles, these devices could deliver scientific payloads to anywhere in the solar system.
