I'm imagining the thought experiment of taking one of those wheels and dragging it through some rocky dirt with 10 kg of weight on it (which I think is about the right load). Because we've only gone a few hundred meters(?) total since the wheel froze, my instincts agree with JayB that it would get nice and shiny but probably wouldn't suffer major structural damage.

Back on topic: here's an annotated version of my previous mosaic pointing at some nearby features: Tsiolkovsky and Von Braun.

Since Sol A 779 we drove about 859 m. I doubt the RF wheel has worn out significantly. It definitely is not like this.

That is a great movie Paolo, I memember watching it live on TV. It was very scary when you didn't know it would turn out.

It looks like Spirit's trying to build a canal.

That is a keeper! - Classic image of the trenching action, and a shadow of Spirit thrown in for good measure.

With these great long drags, is there any concern that we'll start wearing through the stuck wheel?


Well, if we can abrade it down to a nice, smooth surface, doesn't that solve part of the problem? biggrin.gif

We have refined a set of self correcting arcs that seem to work quite well on this type of terrain. It gets more complicated when the terrain is not very uniform and less firm. The Sol 1854 and 1856 drives seem to have been on quite benign terrain.

Probably just a few remains of shrimp tails and a couple of empty Fosters cans that you guys brought from Down Under.
