"If the spacecraft does not receive commands from Earth for seven days in a row, it is programmed to stop whatever it is doing and try to transmit a signal to Earth using its high gain antenna. This could happen at about 0014 GMT on Friday (1614 PST on Thursday), so NASA will be listening for a signal from MGS's high gain antenna at that time." http://space.jpl.nasa.gov/cgi-bin/wspace?t...=1&showsc=1 That would have been a Canberra pass.

Please don't tell me the Cassini periapsis data is being trashed for MGS contingency operations!

I'm sure somewhere someone's thinking "well - that makes us even for when Cassini took our DSN time when it had a problem"

So no news from the Canberra pass?

Maybe that's why there hasn't been any new images from Opportunity for about 48 hours too.

I'm not sure this should be impacting other Mars ops (it may be though...perhaps for AM DFE Uplinks?)

If I remember correctly they can communicate with more than one spacecraft at Mars using the same DSN dish because the antenna beam covers the whole Mars disk and beyond.
As for Cassini: It is a normal procedure that a spacecraft emergency gets priority over normal (Cassini) operations. The same about primary vs. extended missions and manned vs. unmanned missions. It's the way it should be. If they have exhausted their options, MGS is declared lost, not before. Analyst |

Yes. All is well. Though still, giant laser...MGS... Funny you should mention lasers, VP...perhaps the cancellation of the Mars Telecommunications Orbiter should be reconsidered. Lasercomm would be independent of the DSN, and free up resources. (Yeah, I knew what you meant, though...bad planetary scientist, bad!) -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

It's the way it should be. If they have exhausted their options, MGS is declared lost, not before. Oh, I'm perfectly aware of that and I'm not bitchslapping the DSN network for choosing recovery over data playback. It's just that it seemed to happen after a more interesting periapsis pass for Cassini that I find an unlucky coincidence. Unlucky coincidences are what I hate. -------------------- |

yeah, there are contingency plans (woohoo for that). And I hope MGS is recovered, sooner rather than later. I guess it just annoying, that's all.
