NASA's MAVEN spacecraft is still silent at Mars — and apparently is spinning, too

MAVEN (short for "Mars Atmosphere and Volatile Evolution") has been silent since Dec. 4, despite repeated efforts to hail the spacecraft, NASA announced in an update on Monday (Dec. 15). And a fragment of tracking data recovered on Dec. 6 delivered a bit of additional bad news.

"Analysis of that signal suggests that the MAVEN spacecraft was rotating in an unexpected manner when it emerged from behind Mars," NASA officials wrote in the update. "Further, the frequency of the tracking signal suggests MAVEN's orbit trajectory may have changed."
