Excellent news! This really makes my day :-)
I guess this makes it more likely that it is the dust devils/wind cleaning up Oppy also, and not necessarily all the rattling from roving. -------------------- Antti Kuosmanen

Great news! OTOH, I wonder what the long-term effect of the dust devils will be on the atmospheric opacity?
I imagine that dust devils might be less visible at Meridiani because of the desert pavement of the blueberries. --Bill -------------------- |

The atmospheric opacity goes up and down like an excited puppy anyway. Regional and local dust-storms give it trends - but it jumps about from .8 to 1.5 over a period of sols as it is.
But - looking at the Navcam imagery - Spirit's obviously had a cleaning event much like opportunity - that that is BRILLIANT news. Doug |

This must be really bad news for all the tired scientists and engineers
Now Spirit is almost back to Sol 1 in terms of dust buildup. And Oppy has stayed at Sol 1 roughly throughout its mission

Well, NASA can shut the rovers down when they are still working. I fear they will do (and did with Viking)

I think actually - that's highly unlikely. The Voyager/Ulysses funding is a totally seperate pot of cash to the Mars Program - and if nothing else - having two rovers on mars is an excellent way to train people for future missions w.r.t. planning, operations, communication, colaboration, long term planning and so forth - some excellent modes of practice are being put in place that will only benefit ( and save money ) future missions
They only shut down one of the viking landers iirc - and then only by accident The other just died.FWIW - I think we'll find that the public outrage and turning functioning probes off will save Voyager, Ulysses - and the others. Doug |

I find it hard to believe they would shutdown the Voyager probes

At least the MERs are out of range to suffer the same fate as the unlucky Solwind satellite that became the target of brainless military types:

Doug, I really hope it will turn out your way. But I doubt. Btw. the DSN people train with Voyager.

How much of that is real versus different lighting conditions?

The Viking 1 lander died in a very sad way. A young controller sent an erant command shutting it down in 1982 - it may well have lived into the 1990s had this not happened.

Don't know how to find out the time a picture is taken, but looking at the two source images:
http://marsrover.nasa.gov/gallery/all/2/n/...44P0775R0M1.JPG and http://marsrover.nasa.gov/gallery/all/2/n/...76P1875R0M1.JPG It looks about the same time of day to me

I question whether the whole Voyager threat is simply a ploy to keep their budget from being cut. Still, we should take no chances.
