NASA announced that its Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft is now considered unrecoverable after more than a decade of studying the Martian atmosphere. The spacecraft lost communication on December 6, 2022, after passing behind Mars. An anomaly review board concluded that MAVEN could no longer perform its mission due to a battery drain caused by an unusual rotation, which left it unable to send signals back to Earth. Launched in November 2013, MAVEN was the first mission dedicated solely to observing Mars' atmosphere, providing critical data on how the planet lost its atmosphere to space. Major findings include the acceleration of atmospheric erosion by solar storms and the discovery of new types of auroras. The mission has produced over 800 publications and is expected to influence future Mars missions, particularly those involving human exploration. NASA has initiated the decommissioning process and will archive the mission's comprehensive dataset.
