• A pressure drop in the Psyche spacecraft's xenon gas fuel line caused the electric thrusters to shut down automatically.
• NASA engineers are investigating the cause of the pressure drop and are considering switching to a backup fuel line.
• The mission team believes they have until mid-June before the issue significantly affects the spacecraft's trajectory and arrival at the asteroid Psyche in 2029.

NASA's Psyche mission, launched in October 2023, is experiencing a problem with its electric propulsion system. On April 1, a pressure drop was detected in the xenon gas fuel line that feeds the thrusters, causing them to shut down automatically. The spacecraft, en route to the asteroid Psyche, is designed with redundancy, including a backup fuel line. Engineers are currently assessing the situation and exploring potential solutions to ensure the mission stays on course for its 2029 arrival at the asteroid.

• What: A pressure drop in the xenon fuel line of the Psyche spacecraft's electric propulsion system caused the thrusters to shut down. NASA is investigating and considering a backup fuel line.
• Who: NASA, JPL, Maxar Space Systems, Louise Prockter (NASA's planetary science division director), Psyche mission team.
• When: Pressure drop occurred on April 1, 2024. Launched in October 2023. Mars flyby in May 2026. Scheduled to arrive at the asteroid Psyche in August 2029.
• Where: The Psyche spacecraft is currently en route to the asteroid Psyche, which orbits between Mars and Jupiter at a distance of up to 309 million miles from the Sun.

The thruster issue on the Psyche mission, while concerning, appears to be manageable. The redundancy built into the spacecraft's design, including a backup fuel line, provides a viable solution. The mission team's proactive investigation and assessment of the problem suggest a cautious but optimistic outlook. The incident highlights the inherent challenges and risks involved in deep-space missions, but also showcases the resilience and problem-solving capabilities of space agencies like NASA. The earlier launch delays and cost increases due to software testing problems at JPL suggest that the mission has faced hurdles throughout its development.

"This kind of thing happens and that's why we build redundancy into our missions. We don’t have any concerns at the moment about it but we’re obviously keeping tabs on it."

The NASA Psyche mission is currently facing a thruster issue caused by a pressure drop in its electric propulsion system. While this issue has prompted investigation and troubleshooting, the spacecraft's design includes redundancy measures, and the mission team expresses confidence in resolving the problem. The mission remains on track to arrive at the asteroid Psyche in 2029, pending the outcome of the ongoing investigation. The event underscores the challenges of space exploration and the importance of robust engineering and problem-solving.
