Completed TRL 2 (started at 1, targeting 2)
Several targets of interest in solar system exploration require non-solar power sources due to permanent shading from craters or clouds or due to extreme distance from the sun. These missions are typically considered with radioisotope power sources, but the scarcity of such fuel reduces the number of missions that NASA can execute in any decade. This study will explore mission architectures to the Moon's southern Aitken Basin, the surface of Saturn’s moon, Titan, and the surface of Venus that do not rely on Plutonium for power, but instead are powered by a metal-combustion engine. The Applied Research Lab at Penn State has been developing advanced metal combustion systems for power generation through turbines and Sterling engines that have significantly higher energy density than chemical batteries. This NIAC study team will chose one of these missions to study in detail at the NASA Glenn Research Center's COMPASS Lab, resulting in a mission concept report. Proving the feasibility of using metal combustion to power spacecraft in sunless regions would be a breakthrough and shift our expectation of what explorations are possible through Discovery and New Frontiers missions without relying on radioisotope power sources.
This project could enable science personnel on earth to interact and retarget science - something not possible with a ~2 hour spacecraft lifetime. It also allows for contingency operations directed by the ground (reduced risk). The science package was based on that envisioned by the Venus Intrepid Tessera Lander (VITaL) Decadal Survey Study.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 2) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
