This is from a dust-devil simulation on earth, cropped from a Nasa report. Apologies but I can't find the original paper at the moment.

Edited to add the correct figure source [not a Nasa report, but] :

Lunar and Planetary Science XXXV (2004)
MARS EXPLORATION ROVERS: LABORATORY SIMULATIONS OF AEOLIAN INTERACTIONS
Lynn D. V. Neakrase, Ronald Greeley, and Daniel Foley
Arizona State University, Dept. of Geological Sciences, Box 871404, Tempe, AZ, 85287-1404

PDF link to article

Originally pointed by Bruce Moomaw several months ago on the MainlyMartian blog.

Ahhhh... beat to the punch on the cleaning of Spirit's solar cells. Saw it yestererday and while on the way to check past sol's images I wound up chacing other rabbits (a analyst notebook data for a possible halo for Oppy's sol 312).

Great Find (on both the dust devils AND the cleaning of the cells), and Great News!!

Well, it seems that Martian's humor and atmospheric dust levels are closely linked...

Has this been confirmed by anyone?

I'd rather not get my hopes up.

Then so be it.

My hopes are officially UP, and with Ireland on their way to winning the grand slam in the Six Nations, I could not be happier.

This could certainly make them reevaluate their next move.
Will an unfavourable tilt be quite so bad now.
Will they go where previous power levels would have meant a propable death sentance?

Just curious

I thought the panels looked darker. I also looked at the rear hazcam images to see if the thing got much closer to the summit; the front hazcam images weren't much help to me in that respect - the tracks behind it are a lot tougher to see now. Looking at the Navcam images too - yeah, those tracks are definitely eroded a good bit.

Very good to hear that Spirit is back to normal power levels.



And what's this about cut funding for Voyager and other space probes? They damn well better not cut funding for any more operational probes. Hubble's already been handed a death sentence; they better not kill off any other working probes because we don't want to listen to them anymore. The Voyager probes are out in an area never before explored by any spacecraft (the Pioneer craft aren't transmitting anymore); and really, we invested a lot of time and money in building and launching these things. Run them until they won't do a damn thing anymore. Like the rovers - if their wheels seize up completely, fine, leave the cameras running - maybe update the software to allow for rapid image acquisition, and get some videos of some dust devils.
