A healthy NASA orbiter disappeared as usual behind Mars back in December. When the spacecraft reemerged from the other side, it was never the same again.
The U.S. space agency announced June 3 that the Mars Atmosphere and Volatile Evolution mission, aka Maven, is over, after a review board determined the orbiter that has circled Mars for over 11 years is now unreachable.
Though all of Maven’s systems were normal before it rounded the bend on Dec. 6, 2025, something mysterious happened to the spacecraft when it slipped out of view. A snippet of data transmitted to Earth indicates Maven began rapidly tumbling. While mission control would normally only lose contact with the spacecraft for 20 to 30 minutes when it passed behind Mars, the team never regained its signal.
NASA’s anomaly review board, which convened in February, determined this erratic rotation, coupled with dwindling battery power, meant there was no viable way to recover Maven. At a teleconference Wednesday, officials delivered something of a eulogy to the mission, which continued 10 years longer than the team had originally planned.
