The CAPSTONE spacecraft successfully completed a trajectory correction maneuver on Thursday, Oct. 27, teeing up the spacecraft’s arrival to lunar orbit on Nov. 13.
CAPSTONE is no longer in safe mode following an issue in early September that caused the spacecraft to spin. The team identified the most likely cause as a valve-related issue in one of the spacecraft’s eight thrusters. The mission team will design future maneuvers to work around the affected valve, including the two remaining trajectory correction maneuvers scheduled before CAPSTONE’s arrival to orbit at the Moon.
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.
