NASA’s Psyche spacecraft has successfully resumed full-time propulsion after a temporary suspension earlier this year. The mission team detected an abnormal pressure drop in the propulsion system, prompting a halt in operations. However, they were able to reroute the spacecraft’s electric propulsion system to a backup line and restore thruster activity.
The anomaly was attributed to a valve issue in the primary xenon line, which is crucial for the spacecraft’s propulsion system. The team successfully resolved the issue by using the identical backup xenon line, allowing them to regain control of the spacecraft’s trajectory.
With propulsion now back online, the team can continue preparing the spacecraft for its scientific phase without worrying about major trajectory corrections. The Psyche mission remains on track to reach its asteroid target in August 2029, where it will conduct a multi-phase study of the object’s surface, magnetic field, and composition.
The recovery showcases the importance of integrated design, deep system knowledge, and teamwork in spacecraft engineering. The mission team’s dedication and systematic approach to the investigation demonstrate the value of robust spacecraft design and exceptional collaboration.
