So, they might have seen those harmonics from MRO as well as they have not received telemetry from Maven since December 4th and it might well be that Maven is still in its nominal orbit, but having some sort of electrical power outage. Hopefully they will be able to "reboot" Maven soon.

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”.

On December 15th NASA wrote in the Maven blog: “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.

What was thought to be “Maven” is in fact MRO. Proof test by off-pointing our 20m antenna from Mars, but also acid tested when MRO disappeared behind Mars (LOS) – same effect.

Yes, you are right.. MRO is in a ~250 km to ~320 km orbit around Mars, which results in the same orbital period we observed. Will check both again tomorrow, so maybe we received some harmonic frequencies.

Each Orbiter does have different frequencies.

Our own preliminary doppler profile shows that Maven's orbit period is now 1h52m instead of 3h30m. That would be a huge discrepancy. 112 minutes period gives SMA of 3659km. Something odd is going on...

Also visible is the doppler on the carrier frequency, which will allow NASA engineers within a couple of orbits to determine the orbit properties. Fingers crossed, that they will able to fully recover the spacecraft soon.
