NASA has officially ended the MAVEN mission after the Mars orbiter stopped responding in December, apparently after an unexpected spin drained its batteries and knocked out communications. Launched in 2013 and orbiting Mars since 2014, MAVEN spent more than a decade studying how the planet lost its atmosphere and helped explain how Mars transformed from a potentially habitable world into the cold, dry planet seen today. The New York Times reports: The NASA spacecraft MAVEN, short for Mars Atmosphere and Volatile Evolution, had been orbiting around the Red Planet since 2014. NASA last received a signal from MAVEN on Dec. 6, shortly before the spacecraft passed behind Mars. Then the spacecraft stopped responding. A review board found that MAVEN began unexpectedly rotating, causing its batteries to drain too quickly and resulting in a loss of power to the communications system.
"The team is certainly broken up about this," said Shannon Curry, the principal investigator of the mission and a scientist at the University of Colorado Boulder, at a news conference on Wednesday. "But at the same time, we are incredibly proud of the science we've accomplished over the last decade." NASA officials declined to speculate on the root cause of the mishap. A final report is expected to be released later this year.
