Opportunity has a broken wheel motor. (http://www.spacedaily.com/news/mars-mers-05zk.html)
The right front steering actuator stalled on sol 433, on 434 it still wasn't moving. It's about 7 degrees off from straight and could still be driveable if it doesn't get fixed.

Doesn't sound so bad. Check the other topic (http://www.badastronomy.com/phpBB/viewtopic.php?p=456825&#456825).

No more than a Vostok capsule is within sight of nearby Vostok Crater.

The craters are named after famous vessels/craft of discovery.

Ohhhhhhh! What a disappointment!

I was hoping to see at least one of the Voyagers at the bottom of Voyager Crater!

Now that would be a conspiracy!

New pictures from Opportunity at JPL, still no driving though. I have the awfu feeling that Opportunity's journey is coming to an end. :(

Or maybe they are just checking all possibilities, just to prevent damaging things any further. I assume they can just drag the wheel along -or lift it up- and continue driving if the wheel turns out [pun unintended, and unnoticed at first :)] to be irreparable.

Hasn't Spirit been dragging one of its wheels for months now? Or did they get it fixed?

Link to Squyres update in the Vostok to Victoria thread. They've been having software problems - nothing to do with the gimpy wheel. They're on the move again, but now Oppy is sinking into the sand more than they expected, so probably more delays coming up.

These Rovers have been great, its so good that they have done so much work and returned such images + data

However opportunity-rover looks like its in trouble

Remind anyone of the motors in Dakar ?

All of Spirit's wheel motors are working correctlly, now. Last fall, by running the rover backwards, the wheel lubrication redistributed itself and the wheel started working correctly. Now, that is part of standard operating procedure for both rovers -- to periodically run backwards to keep the lubrication distributed.

It looks like Opportunity was driving backwards at the time it bogged-down. The front hazcam is looking back along the wheel tracks, and the rear is looking towards undisturbed sand.
