Here's a gamma-tweaked animation of the right rear hazcams from 2072 and 2078:
Attached Image

You can see the LR wheel has been steered more straight, and presumably driven as well. Can't see the RR wheel. Front hazcams show RF wheel was steered straight as well.

I also would expect underbelly MI imaging. And also pancam images of the middle wheels.

Thanks, Sunspot. =)

Yeah, I'm sure they'll image the underneath.

Another momentous moment for the rovers. Good luck to RoverDriver and rest of the team!

Exciting to see at least some movement. It almost looks like we might be taking the forward option? From the data available it is hard to judge whether it is more probable that we will get out or not, but being an optimist I think we will eventually inch our way out in time to find a wintering place.

May interest some people ....... just posted a version 3 of the Sol 2002 (Aug21st) sunset movie on YouTube with the sun continuously tracking down to give a more realistic effect. Will do some final corrections/colour adjustments on a V4 soon.

Maxwell tells us that this move only involved steering, not driving the wheels.

But it looks as if the LR wheel sank further. Given Maxwell's indication that only steering was involved is the downwards movement really good?

We far far FAR too early in the extraction process ( step one of dozens and dozens and dozens of steps ) to say if it's good or not.

But it HAS started, and that's reason to be happy.

If you're going to be negative every time any motion doesn't correlate with your expectation of how things should or shouldn't go, you're going to go very very mad, very very quickly.

Downward movement when steering only would be expected as that's what happened when it was done previously (before they attempted a turn in place)

I recall roverdriver mentioned testing spinning the wheels while steering was tested to determine if it reduced the downward movement.

So RF and LR wheels were steered on 2078, and now LF and RR wheels steered on 2079. It's really hard to see what's happened with the RR, but if you compare the 2078 and 2079 images:
http://qt.exploratorium.edu/mars/spirit/re...03P1304R0M1.JPG
http://qt.exploratorium.edu/mars/spirit/re...04P1314R0M1.JPG
the soil behind the RR has moved quite a bit, perhaps looking as if the RR was actually driven. But my guess is it was just steered like all the others.

This is definitely all good news - finally the extraction has begun! smile.gif
