I hope my sources don't get in trouble, but these are too good to keep to myself! These are enhanced animations from Sol 456 and 459. Amazing quality.

No wonder Spirit got some dust lifted by something like that
![]() Seriously, that is just bloody awesome! Thankyou Spirit for living so long and giving us the opportunity (no pun) to see something like this! ![]() -------------------- "I want to make as many people as possible feel like they are part of this adventure.

Oh my God! I just saw them. What can you say! I never thought we would see anything like that. I could practically hear them as they went by. Intense.

Clever way of getting the details of the devils from the images too. jG Yes, I didn't have time to apply this enhancing method to this sequence (though I already used something like this in the analysis of a devil track: http://www.unmannedspaceflight.com/index.p...indpost&p=8673). Very interesting strategy also for JPL devils detection/transmission...! ![]() -------------------- I always think before posting! - Marco -

I don't want to see them on Spacedaily, attributed to this forum ![]() I am totally blown away. This is what I mean about seeing alien vistas. BTW -- the Sol 456 event (I think it was, the middle one of the first three Doug posted) seemed to pass rather close to Spirit. Does anyone know whether or not the solar panels were affected, either way? I mean, the devils pick up dust, but they also look like they could drop dust in their wake, too. Considering how quickly the air thins out with height, I'd think that small devils like these might be dropping dust fairly close to their paths. I'm hoping we don't get showered with so much dust at any point that power levels drop as fast and far as they rose after the first major cleaning event... -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

QUOTE how they do the "remove the background" thing You have two images of the same scene taken without moving the camera and digitally subtract one from the other. In theory, they ought to cancel out and give a black image. In reality, there is a difference in the JPEG artifacting and the residual thermal noise of the camera so you won't get _zero_. If one image contains something different, like a dust devil or a tribble, the different material will left and emphasized. In these images, they then added or overlayed the "enhanced" dust devil back into the scene for aesthetics. A standard PShop function. --Bill -------------------- |
