NASA Teams Work MAVEN Spacecraft Signal Loss

NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN) spacecraft, in orbit around Mars, experienced a loss of signal with ground stations on Earth on Dec. 6. Telemetry from MAVEN had showed all subsystems working normally before it orbited behind the Red Planet. After the spacecraft emerged from behind Mars, NASA’s Deep Space Network did not observe a signal.

The spacecraft and operations teams are investigating the anomaly to address the situation. More information will be shared once it becomes available.

The MAVEN spacecraft 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 solar wind to explore the loss of the Martian atmosphere to space. Understanding atmospheric loss gives scientists insight into the history of the Red Planet’s atmosphere and climate, liquid water, and planetary habitability. The spacecraft also serves as a communications relay station for rovers on the Martian surface. Last year, MAVEN celebrated its 10th anniversary in orbit at Mars.
