I wonder if Steve Squyres is still interested in taking another look at Fuzzy Smith. It looks like Spirit will be be passing right by it after mounting Home Plate. Does Fuzzy still hold the record for silica content?

"...loose rocks atop Home Plate include the small, irregularly shaped rock Fuzzy Smith. It has the highest silica content reported to date (May 2007) on the mission. Scientists believe hydrothermal processes "bleached" out the primary elements in the rock, leaving the silica behind."

Alan, I'm not seeing it. Did you accidentally post the same pair of images? The image IDs are the same.

The IDs are not the same, somewhere in the middle of the ID, and if you flip there is a VERY faint effect - alan has some kind of freaky super-powers to catch that. It's easier to see above the horizon than below it.

Here's a pic made by subtracting one from the other, cancelling out everything except the DD and noise/JPEG artifacts. The arrows point to the two images of it as it moves. The image subtraction leaves one white and the other black.

Yikes, that's pretty subtle. I had noticed what looks very much like a devil on 1784. Here's a crop of the navcam view. There's no other frame to see the motion of the devil, but at least this one looks kind of like a dd!

Well, it's great to finally see Spirit on the move again. Let's hope one or two of those dust devils she's seeing will come on over and give her solar panels a much needed cleaning off. Here''s hoping.... pancam.gif smile.gif

I see a couple more in the sol 1799 navcam subframes. The 2009 dustdevil season is underway. dd.gif

On another note Spirit, at sol 1801, is now beyond 20x the primary mission.

But you will need to turn the amplifier up a little bit more past 10 when you play it.
This image just in from the OPPY navcam..

Perhaps this will answer important scientific questions, such as "who they were" and "what they were doin' "..

(also.. Sorry!)

Nah - that's obviously a natural formation. Nothing to get excited about.

Back to reality...

Did Spirit just have an un-drive? The new pictures look like post-drive imaging, but she didn't seem to move a mm.
