Canceled TRL 6 (started at 3, targeting 6)
Develop a highly-efficient (>95%), low-mass (1kW/kg), high-density (2W/cm3), distributed power subsystem for in situ platforms on the Moon and beyond. The developed system will provide common power and communications busses for all units, enabled through distributed digital control, distributed bus converters for >95% efficiency to loads with localized digital control/telemetryDistributed load switches & linear heater controls to maximize thermal system efficiency, common modules that can be used throughout rover, orbiter, or base power distribution systems
Distributing power system elements enable compact, modular, power subsystems, creating a platform to enable SWaP-C improvements on a wide variety of lunar mission types. By moving power system elements throughout the spacecraft, point-to-point harnessing is eliminated, communications systems are simplified, and numerous architectures are enabled. JPL and GRC will develop several modules within the distributed power subsystem that can be used to form the architectures of numerous mission types. The developed modules will leverage JPL IRAD support for radiation-hardened GaN conversion systems and GRC support for the HEO AMPS program. JPL and GRC, along with commercial partners, will then integrate a full system for demonstration CLPS lander and AMPS payloads (500W - kW) and evaluate in relevant lunar environments to improve from TRL 3 to TRL 6.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 6) — 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.
