On December 6, NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN) spacecraft, which has been studying the Red Planet’s upper atmosphere for over a decade, mysteriously went offline. Less than a week later, NASA issued a new update, admitting that MAVEN appeared to be “rotating in an unexpected manner when it emerged from behind Mars.” Then, on December 23, the agency issued its last update, promising that it’s “continuing efforts to recontact” its lost spacecraft. Mars’ solar conjunction, a weeks-long period when Mars and Earth are on opposite sides of the Sun, will end on January 16, which will give NASA a new opportunity to reestablish contact. It’s a sad state of affairs, but fortunately there are three other spacecraft that can still relay communications between Mars missions and the Earth.
