Did nobody notice this:
Ground Team Stays Busy on 10th Anniversary of NASA Mars Launch Ten year after launch, there is some trouble with a solar array motor and a comm problem probably resulting from this and entering safe mode. Nothing dramatic yet, but something to follow closely. There are other things than MRO and MER Analyst |

Odyssey or MRO to MGS UHF comms - I've not thought of that but it should be possible - however I imagine that the signal strength pattern from the UHF antenna would require a serious spacecraft manouver for it to work. Very interesting idea. But first you have to turn on the UHF receiver on MGS (including MOC). And you can do this via X-band only (I assume UHF and all instruments are off in safe mode.). I wonder if you can get commands to MGS via UHF from Odyssey or MRO. But why do this if you can command via X-band? So you need X-band commanding first, and if you have X-band commanding you don't need UHF (Except maybe to save power?). Analyst |

Using the UHF, is it to try and send something from the rovers to MGS and then try and relay via Odyssey or use the rovers to try and listen in to see if the MGS is transmitting anything via UHF and then relay the results via Odyssey?
I read an article that mentioned it this morning but can's see it now Edit: Ah, never mind QUOTE The beacon signal would not contain any information, but its detection would at least indicate that the spacecraft is alive and able to respond to some commands. If the rovers heard the signal, they could notify another NASA orbiter
