MAVEN status update

NASA's MAVEN spacecraft entered safe mode on Feb. 16 after encountering an issue with its Inertial Measurement Unit (IMU), which measures the spacecraft rate of rotation for use in determining its pointing. The IMU had been powered up in preparation for a minor maneuver targeted to reduce eclipse durations in 2027.

On Feb.17, MAVEN exited and is currently operating in all stellar mode, a mode that does not rely on IMU measurements such that the IMU can be powered off to conserve its lifetime. The maneuver will be waived as the team evaluates the path forward. Relay activities and nominal science operations are scheduled to resume on Feb. 23.

MAVEN launched in November 2013 and entered Mars' orbit in September 2014. The mission's goal is to explore the planet's upper atmosphere, ionosphere, and interactions with the Sun and to explore the loss of the Martian atmosphere to space. Understanding atmospheric loss gives scientists insight into the history of Mars' atmosphere and climate, , and planetary habitability.
