The CAPSTONE spacecraft executed a planned trajectory correction maneuver on Thursday evening, Sept. 8, and CAPSTONE mission controllers have since obtained telemetry confirming that an issue put the spacecraft in safe mode near the end of the maneuver. The CAPSTONE mission team has good knowledge of the state and status of the spacecraft. The mission operations team is in contact with the spacecraft and working towards a solution with support from the Deep Space Network. Additional updates will be provided as available.

CAPSTONE – short for Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment – is owned by Advanced Space on behalf of NASA. The spacecraft was designed and built by Terran Orbital. Operations are performed jointly by teams at Advanced Space and Terran Orbital.
