                                                              NASA's Mitigation Strategies

                                                              NASA's mitigation strategies have been a cornerstone in handling unexpected events such as the recent pressure drop in the Psyche spacecraft's propulsion system. One of the primary strategies is the integration of redundant systems, which is crucial for maintaining mission integrity when issues arise. For instance, the Psyche spacecraft is equipped with a backup fuel line, allowing the mission team to bypass the primary line if it's identified as faulty. This redundancy ensures that the mission can proceed with minimal disruption, demonstrating a proactive approach to spacecraft design .

                                                                In addition to hardware redundancies, NASA employs rigorous investigative procedures to diagnose and rectify anomalies. The current issue with the Psyche mission involves detailed assessments by engineers at the Jet Propulsion Laboratory, who are scrutinizing potential problems within the fuel line and other mechanical components . By methodically evaluating both internal and external factors, NASA ensures that any decision to employ backup systems is well-informed and optimized for success.

                                                                  Moreover, NASA's strategy includes leveraging institutional expertise and industry partnerships to enhance mission resilience. Engaging with experts who understand the nuances of space exploration allows NASA to adapt quickly to technical challenges, such as those faced by Psyche. As noted by Louise Prockter, incidents like these are accounted for in mission planning, ensuring continuity despite unforeseen complications . This capability to anticipate and mitigate risks effectively underpins NASA's overall mission strategy.
