"Hey folks! I’m on-duty with Opportunity this week and it’s going to be pretty exciting. We are in the process of driving the rover over to the wall of Cape Verde to study the layers of rocks there in much greater detail. I will be posting updates all week with the spectacular new pictures that we should be receiving. Stay tuned, it’s going to be a pretty cool week!"
Thanks for the update Ryan : http://martianchronicles.wordpress.com/200...ng-to-the-cape/ I wonder how close they'll get. I think no closer than the height projected from it's base ( i.e. 45 degrees ) |

There are some fresh pictures on the Exploratorium of the latest move by Opportunity during sol 1495.
The latest significant drive was on sol 1491 (check the route map) and there were two "drive attempts" after that one, on sols 1493 and 1495, both of them resulting on tiny uphill movements. Have a look to the fhazcam shots from those sols here below (gamma corrected). Don't you think the forward left wheel is sliping and digging in the soil?

Don't you think the forward left wheel is sliping and digging in the soil? I'd say it is digging in, to a small depth. But of course on such a steep slope even a small amount of slippage is concerning. When you look at these images it's easy to forget about the slope and mentally "subtract it off".On the other hand, we apparently have bedrock not far below the surface here. And the best rover drivers in the solar system at the wheel. I have to say though that I'm surprized that it appears they intend to take a direct route to the target, over this sandy surface, rather than following the exposed rock to the left (upslope) as far as possible, before heading downslope. Perhaps they've chosen the route with the shallowest slopes. |
