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.
  Disclaimer: These come from JPL, but NOT OFFICIALLY. They have been modified by me to reduce file size. I don't want to see them on Spacedaily, attributed to this forum  . Seriously. Enjoy the sneak preview, and wait for JPL's PR people to catch up.

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!

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.

Very interesting strategy also for JPL devils detection/transmission...!

Enjoy the sneak preview, and wait for JPL's PR people to catch up.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

Oh sure get a little busy at work and life for a couple days, come back and see i missed all the excitment.
 Anybody know how they do the "remove the background" thing at jpl? remove everything that is the same and leave everything that is different? Would be nice to do to the earlier dd'shttp://marsrovers.jpl.nasa.gov/gallery/pre.../20050421a.html scott |

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 -------------------- |
