Cattle Run Proposers Day Announcement

PROGRAM OBJECTIVE AND DESCRIPTION: The Defense Advanced Research Projects Agency (DARPA) Cattle Run program enables cost effective cislunar constellations by developing and demonstrating autonomous spacecraft that leverage renewable propulsion [EF1.1]for persistent cislunar access. Phase 1 develops and rapidly launches a[SK2.1] Demonstrator spacecraf[SK3.1]t in 18 months that shows the ability of renewable propulsion to achieve sufficient acceleration, accurate vehicle control, and autonomous navigation necessary for persistent cislunar access. The Phase 1 objective is to collect on-orbit data to prove the performance of the renewable propulsion approach including vehicle control and navigation data. The Demonstrator spacecraft is launched below GEO and is agnostic of formfactor. Phase 2 creates multiple spacecraft and demonstrates persistent cislunar access.
