Description
DARPA’s Cattle Run program aims to enable cost-effective cislunar constellations by developing and demonstrating autonomous spacecraft that use solar sails or other renewable propulsion for station keeping and maneuverability over long missions. Initial work focuses on rapidly developing and launching a demonstrator spacecraft below geosynchronous orbit to demonstrate propulsion, vehicle control, and autonomous guidance, navigation, and control; later objectives include multiple spacecraft demonstrating cislunar operations. The Proposers Day provides program information, discussion and questions, and opportunities for potential proposers to meet and explore teaming. Attendance is voluntary and is not a prerequisite for responding to a future solicitation. Registration is required, attendance is limited, and attendees must be U.S. citizens, meet the stated CMMC Level 2 requirements, and submit the required citizenship verification form.
