Maybe it got hit by a roadster... what a bad luck that would be... good luck filling the insurance papers

NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN) mission team, in partnership with the agency’s Deep Space Network, continues recovery activities after losing contact with the spacecraft on Dec. 6. To date, attempts to reestablish contact with the spacecraft have not been successful.

Although no spacecraft telemetry has been received since Dec. 4, the team recovered a brief fragment of tracking data from Dec. 6 as part of an ongoing radio science campaign. Analysis of that signal suggests that the MAVEN spacecraft was rotating in an unexpected manner when it emerged from behind Mars. Further, the frequency of the tracking signal suggests MAVEN’s orbit trajectory may have changed. The team continues to analyze tracking data to understand the most likely scenarios leading to the loss of signal. Efforts to reestablish contact with MAVEN also continue.

NASA is also working to mitigate the effect of the MAVEN anomaly on surface operations for NASA’s Perseverance and Curiosity rovers. Four orbiters at Mars, including MAVEN, relay communications to and from the surface to support rover operations. NASA’s Mars Reconnaissance Orbiter, Mars Odyssey, and ESA’s (European Space Agency’s) ExoMars Trace Gas Orbiter all remain operational. For the next two weeks of scheduled surface operations, NASA is arranging additional passes from the remaining orbiters, and the Perseverance and Curiosity teams have adjusted their daily planning activities to continue their science missions.

Huh... That really does sound like it got hit by something. Something small though, not quite roadster sized...

Or something vented, propellant and/or pressurant, and maybe that is why it hasn't stabilized to point the antenna back home.

Mabye it vented because it got hit by something!
