“After the spacecraft emerged from behind Mars, NASA’s Deep Space Network did not observe a signal,” the agency said in a press release on Dec. 9.
Officials added that “the spacecraft and operations teams are investigating the anomaly to address the situation.”
MAVEN reached orbit around Mars on Sept. 21, 2014, to study the composition of the planet’s upper atmosphere.
