On Friday, October 7, Capstone crew members successfully performed an operation to stop the spacecraft’s rotation. This removes a major obstacle to the spacecraft’s return to normal operations.
Following the course correction maneuver scheduled for 8 September, CAPSTONE encountered a problem Put the spacecraft in safe mode. soon find out The spacecraft was turning The internal reaction goes beyond the ability of the chakras to control and resist. According to the spacecraft data, the problem could be related to a valve in one of the spacecraft’s eight thrusters. Partially open valve indicates thrust as a false thrust is generated each time the thrust system is pressed. After a thorough analysis of the telemetry and simulation data, the mission team performed several tests on the spacecraft to develop a plan to stop the spacecraft’s rotation despite this problem.
Rescue orders were activated on Friday morning. According to preliminary Coronation telemetry and tracking data, the maneuver appears to have been successful, indicating that the spacecraft has stopped its rotation and regained full control of the three-axis position. This means that the CAPSTONE position can be controlled without unplanned rotations. CAPSTONE now directs its solar panels towards the sun to increase energy production. It also changed the pointing of its antennas to provide better data communication with the ground.
The risks of this anomaly and the recovery process are significant and the team has worked extensively and collaboratively to reduce these risks. In the coming days, the team will continue to monitor the condition of the spacecraft and make necessary changes to procedures to account for and mitigate the effects of the partially open thrust valve. The staff will also try to design possible solutions to this valve problem to reduce the risk of future maneuvers.
CAPSTONE is about to enter a straight halo orbit around the moon on November 13th.
