This looked extremely promising, though I guess we'll have to wait upon the official word on how they thought it went.

My first contribution:



Movement for sure!

Looks encouraging!

Seeing the stuck right wheel slide made me wonder if the tread on the bottom of the wheel has worn off by now? Has this been discussed? According to this quote I found on a NASA site "At 26 centimeters in diameter (a little over ten inches), these aluminum wheels are twice the size of those on Sojourner" it appears the wheels are aluminum which is soft. Spirit has been dragging the wheel for a while and sometimes over hard material such as on home plate. Is it possible that the tread on the bottom is now completely worn smooth? Did NASA use a worn tread right front wheel when doing sandbox tests? (I suppose if the treads are caked with material anyway it might not make much difference, but for future mobility over hard material it could be adventageous if the tread is now gone) (at the very least it is good the wheel froze without the criss-cross-lander-attachment-point-tread pointing down!)

Had the same thought.

There appears to be a 1 pixel drop on the left side of the horizon in the front hazcam views between 2088 and 2090. That corresponds to a pitch up at the front by about 0.1 degree. There's a corresponding lift of the right side of the horizon in the rear hazcam views. Considering that that may have more to do with rocker/bogey than wheels, that sounds like nothing to write home about to me.

The movement of the horizon in the front hazcams appears to be mainly a shift to the left. That means the rover is yawing clockwise as viewed from above, which is what you'd expect with the dead RF wheel. Again though, the yaw angle is very small.

MIs are consistent with us moving forward. It's really good to see LF eating into the soil in front of it, and the RF make progress too.

Tweaked rear hazcam comparison, 2088 to 2090:

Right! I tried to match features on the pile in front of the LF and a lot of the face of the mini cliff in front of the LF seems to have fallen away, but there is no pile of fallen material visible. In fact, a pile of material (orange arrows) that was present before the drive is also missing.

Before drive.............. After drive

From the latest update:

And this was really interesting - she actually made too much progress in her first step, so the second was cancelled!

Here is a little animation of the underbelly of Spirit (sols 2088 -2090)
I dusted off the program that s t r e t c h e s the heck out of the histogram of the images (no respect for gamma)

Wow! That RM cleaned up nice! The LM seems to have dug in, but I like those clean cleats on the RM -- ready to grab hold and push the RF along.

Another 600m and we're out

as the most annoying thing of sand is it keeps falling on you while you dig... would it be possibile for the IDD to remove the sand over the wheel, to prevent it from burying the wheel itself?

EMBEDDED IMAGE REMOVED - please either attach images or post links to them offsite -- embedding makes life difficult for people with slow connections or small screens.

The IDD is not a shovel........so NO.

never mind what it is designed for, think of what it CAN do! "Think lateral" , or we'll never get out of there!

There is no way they are going to be shoveling with the IDD. MahFL was being polite by just saying NO.
