SURFACE POWER EXCHANGE CONNECTOR (SPEC)

The Surface Power Exchange Connector and its associated hardware are designed to create a standardized, plug-and-play interface for transmitting power between lunar surface electrical power systems and consuming equipment, ensuring seamless energy exchange across diverse assets such as the Pressurized Rover, Lunar Terrain Vehicle, Fission Surface Power units, and habitats. This common interface is defined by the Lunar Surface Integration Phase Power Specification EHP-10069 and enables interoperability among systems developed by different teams or contractors, reducing complexity and enhancing operational reliability on the Moon. The connector architecture includes a fixed-mount component integrated into vehicles prior to launch, paired with a separate mobile cable end for flexible power transfer, allowing for adaptable connections without requiring permanent reconfiguration of hardware. The initiative is led by NASA’s Johnson Space Center under a forecasted procurement with a NAICS code of 541330, targeting advanced engineering and technical services to support lunar infrastructure development. While no solicitation number has been issued yet, the posting date indicates the opportunity is anticipated for 2026, with point of contact information provided for technical inquiries and small business engagement. The effort aims to standardize power transfer mechanisms across the Artemis program’s surface systems, aligning with long-term goals for sustainable lunar operations by minimizing proprietary interfaces and supporting scalable, modular power distribution across the lunar surface.
