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.
