Free Spirit website now up, featuring a video of TeeBee's embedding with a familiar face or two hard at work... smile.gif

Watching the video is actually quite illuminating. Question: It seems like just spinning the wheels might facilitate letting Spirit slide slowly down the slope. Given the fact that the pointy rock is looking like less of a hazard, would this be a good extraction strategy? I suspect that there's some fear that even deeper dust lies at the bottom, but gotta ask.

Nice comparison, Astro0!

Actually, TeeBee's rock looks scarier than Spirit's in this view.

This is a question for the rover drivers:

What is the upper and lower limits for the 'shutter speed' (the time a picture could be taken) of the MI?

I guess a corollary is what are the units between them...?

at your convenience,

You are right, but in the ISIL I had a limited set of rocks available. It needed to be small in size, tall enough to reach the WEB, and shaped with a pointy end.

I don't know. Probably there is a published paper that describes the Pancam. The cameras on MER are all the same, the difference is just in the optics.

According to the Pancam technical paper, the integration time for the CCD's can be between 0 - 335 seconds in 5.12ms steps

Why do the words "underground lair" come to mind when I see this photo?

Test bed

Between the lab coats and the test machinery, the image is evocative of a Bond Villian set up!:D

I don't know. I think mad scientists bent on world domination would at least spring for a couple of LCD monitors. wink.gif

Paolo definitely has the look of someone who could turn into a Blofeld if pushed over the edge! Be nice to him!

I don't think they would let a Persian cat in the test bed. Not only because of the fur, but that big box filled with sand might prove too tempting. Ewwwww.
