What about collecting into a single thread all cool animated GIFs about Phoenix activities?
A possible list of cool images is: - soil digging - ice scraping - TEGA filling - ice melting - dust devils - sunset/sunrise - snowing Thanks for your contribution! Direct links to images, or even attachments, would be better than just links to pages which link to images. Standalone page with inline animations: http://www.planetmobile.it/jumpjack/immagi...ni-phoenix.html |

I don't want attachments doubled up purely to be put into an animation thread. If they're already on the forum, link to the post they're in.

Off site animations are even better. There is a nice, off site gif animation of frost accumulating on the telltale mirror here.
QUOTE Bright specks of frost accumulate on the mirror of the telltale on NASA's Phoenix Mars Lander in this series of images taken between 12:54 a.m. and 2:34 a.m. at the landing site during the 80th Martian day, or sol, of the mission (on Aug. 15, 2008). Here is an off site animation of a dust devil from the same Canadian site. QUOTE "It was a surprise to have a dust devil so visible that it stood with just the normal processing we do," said Mark Lemmon of Texas A&M University, College Station, lead scientist for the stereo camera. "Once we saw a couple that way, we did some additional processing and found there are dust devils in 12 of the images." It still blows my mind to realize I am seeing dust devils on the northern arctic plains of Mars as winter approaches. This is indeed a strange planet. -------------------- ...Tom

DD even at pole?!? really a weird planet. I thought DD where caused by warm/hot air... |

Yes - they've been observed from orbit, and now from the ground. They're caused by relative heat - not just heat per-se.

Sorry if it has already been said here, but I wonder if they use the same kind of software as MER's to image DD?

No - the PHX and MER avionics are quite different.

What amazes me is not that we're seeing dust devils -- as Doug said, it's all a matter of relative temps, as long as the differential is of the right magnitude, it doesn't really matter what the overall temperature state is.
No, what amazes me is that there doesn't seem to be any albedo impact from these DDs. In other regions, DD tracks are quite obvious and even prominent. Here, there was no trace of such DD "leavings" in any of the HiRISE images of the area. It's not because the soil is of uniform albedo -- we can see very clearly that the soil disturbed by Phoenix's landing thrusters is much darker than the undisturbed soil. Also, soil disturbed by impact from the heatshield and backshell shows a distinct darkening. Why, then, if DDs roam these plains, are there no DD tracks? That's the really fascinating question here, to me. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

No enough dust?

Maybe they just need to take another Hirise image? MOC images of the Phoenix latitude band show lots of dust devil tracks, even if the hirise of Phoenix did not. So, maybe they fade quickly, but are there now. Or, maybe these are just too small. Only one or two of the Phoenix dust devils favorably compare to the typical Spirit dust devils. The rest are smaller and pick up much less dust.

Or - maybe there are streaks being created by these DD's - but - in the same way we couldn't see the heat-shield at first - the lumpy bumpy nature of the terrain hides them?
