The GRAIL and LADEE missions demonstrated the inherent value of skimming low over the lunar surface, yet they only probed below 10 km very briefly during periapse passages. Advanced Space proposes developing the means for flying spacecraft in an orbit that remains below 10 km altitude for weeks or months, opening the door to breakthrough scientific investigations. The proposed work will study an innovative system that may be used to achieve Sustained Low-Altitude Lunar Orbital Missions (SLALOM), enabled through autonomous onboard GNC capabilities and the use of Flash LIDAR.The proposed study explores the dynamics of SLALOM, performs navigation analyses, evaluates maneuver planning methodologies, and researches how unique innovations in spacecraft autonomy can transfer operations from the ground to the spacecraft. Skimming the lunar surface autonomously with a spacecraft that remains below an altitude of 10 km is a challenging proposition that requires an entirely new approach to spacecraft navigation, maneuver design and execution, and spacecraft autonomy. SLALOM, with the requisite breakthrough improvements in guidance, navigation, and control technology, allows new scientific investigations such as the direct sensing and/or capture of lunar particles naturally lofted by the complicated dynamics of the lunar exosphere. The benefits of the proposed innovation in spacecraft autonomy extend naturally to other airless bodies where sustained low-altitude orbits are mission enabling. These include, among others, the scientific and commercial exploration of asteroids and the Martian satellites Phobos and Deimos. While these applications are compelling, Advanced Space identifies the Moon as an ideal proving ground for this technology for many reasons, not least of which is to take advantage of the wealth of geodetic reference data generated by previous missions and the desire for low-altitude, high value scientific investigations identified by the lunar science community.
