Optical Wireless Technology for Lunar to Mars

Introduction: This SBIR supports NASA's need for Optical Wireless Power Transfer (OWPT) for the Lunar and Mars human exploration missions. Supports power distribution from solar and fission surface generators where wired cabling is costly, impractical, or unsuitable for mobility needs. The SBIR can support a space tech demo in the 2028-2031. OWPT can dynamically deliver power, provisioned within minutes, anywhere within a 20 km radius vs wired deployable tethers or RF wireless out to ~ 1 km. Limitations of Traditional Power Generation: Conventional power generation methods are limited to fixed locations with wired power distribution lines serving nearby areas around landing sites. Long-range power distribution utilizes high-voltage transmission methods for point-to-point power delivery, which is suitable for fixed locations. NASA and others are testing long wire or fiber optic deployable tethers to support mobile power up to approximately 1 km, beyond which challenges arise. On Earth, mobile power is typically provided by gasoline and batteries. Addressing NASA's Commercial Shortfall: This SBIR addresses NASA's Space Technology Mission Directorate (STMD) Commercial Shortfall List Priority #12 (1591). The benefits of OWPT include supporting longer-range deployment of mobile vehicles, Benefits of OWPT Technology: • Provides power for ISRU prospecting, mining, and construction vehicles within PSRs. • Offers dynamic power delivery with a 20 km line of sight. • Extends the reach of solar, fission, and fuel cell generators over large area. • Supports mobile operations lasting days to weeks away from a landing site, reducing the need for direct power source connections. • Enhance mission productivity, flexibility, less wear and tear on mobile equipment traveling to wired chargers. • Nighttime Power Distribution: Distributes nighttime power for operations, ensuring survival through the night. • Provide Lifeline power to mitigate anomalies
