NASA Ends Mars Mission 6 Months After Losing Communication With Spacecraft

NASA’s MAVEN mission is observing the upper atmosphere of Mars to help understand climate change on the planet. MAVEN entered its science phase on Nov. 16, 2014. NASA's Goddard Space Flight Center

After more than a decade of service, unlocking treasure troves of insights into Mars’s atmosphere, NASA announced on June 3 that its MAVEN mission has come to an end after a still unknown anomaly threw the spacecraft off course and drained its battery.

Short for “Mars Atmosphere and Volatile Evolution,” NASA’s MAVEN mission launched in November 2013 to study the Red Planet’s atmosphere, specifically how it interacts with solar flares and other types of space weather, as well as readings of the dust storms. The mission was supposed to last one year, but the hardware continued to operate for another decade, providing insights crucial to sending a human crew there with the right protection in the future. It was also able to give ground systems early warning of incoming coronal ejecta from the sun.
