Completed TRL 3 (started at 2, targeting 5)
This project is focused on maturing future surface exploration technologies and instrumentation and working towards flight instrumentation and systems to support future robotic exploration efforts. The main portion of this project advances a JSC remote sensing method employing passive wireless surface acoustic wave (SAW) devices integrated with a retro-reflector antenna and mounted on a penetrator probe. Placement of the penetrator probes into the surface layers of a small body would allow direct measurements of surface temperatures, temperatures at multiple points around the body of interest, surface and subsurface temperature measurements over multiple diurnal cycles, surface feature movement and precise relative navigation aid
The small size and low weight of these battery-free SAW tags enable long-range, long duration remote temperature sensing instruments as well as a relative navigation waypoint network. This project can eventually provide a unique scientific instrument to be flown on multiple robotic probes. Additional exploration technologies will be identified and assessed for their applicability for future surface, small body and planetary exploration (e.g. Naval Research Lab miniature microbial fuel cell, modulating retrroeflector, X-band switchable radio/radar).
Outcomes: Analyses for system performance in a deep space environment, breadboard-level hardware fabricated for laboratory testing, preliminary system concept for a flight quality article
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 3) — 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.
