I spent a few minutes this last weekend trying to stitch together some raw images from the Mars Rover site into a panorama. Well, today I see they've posted just the panorama I was working on. The JPL image guys are awesome and they've certainly done a better job than I could have so I'm happy to see this nice mosaic arrive. You can find the medium resolution version here and the high resolution version here.
I've just begun work on a new mosaic from the Opportunity raw imagery. I've combined a couple of images, cleaned up a lot of noise and burned areas, and colorized it for fun. You can see the low resultion version here and the higher resolution version here. (If you're interested in the full resolution version, let me know and I can make it available for a short period of time.)
That hill in distance is actually Endurance Crater's rim. Opportunity spent the better part of last year rolling around in that crater and only recently surfaced. A bit closer in the image, you can see the wreckage of Opportunty's heat shield which just happened to be in her path as the trek southward began.
