Is there a significant risk of getting stuck if Oppy rolls over one of these rocks?

Wow, will ya look at that...
http://twitpic.com/zysql/full Are they shattercones littering the area? Or has the rock just fractured at sharp angles? Can't wait to see some of those stones in more detail... -------------------- |

"Are they shattercones littering the area?"
I wouldn't expect shatter cones in a tiny impact like this. Phil -------------------- ... because the Solar System ain't gonna map itself.

Hmmm. Interesting rock on the bottom of one of the latest images... Wonder if this is what we'll see a lot more of when we get to the crater itself..?

Yes, we're very near Conception, and we see clearly the "star" structure of the ring of ejectas, I think. And we can see like a dark streak on the horizon Endeavour. Can't wait to have the pancam's -------------------- |

We are sitting now on one of the most scenic place either rovers ever been on Mars. A fresh 1000 years crater, opening view to our destination, others big craters in sight, Victoria still to find in our rear mirror. We'll be there for a while, guys.
Time to open a new topic. Enjoy your stay. -------------------- |

Many, maybe most of the rocks seem to be sitting on the drifts - very few seem embedded. And there's no sign I can see yet of wind tails behind rocks or moat-like troughs wrapping around the base of rocks (compare with the Barnacle Bill area at Pathfinder to see what I'm referring to). I take that to mean that the drifts have hardly changed since the crater formed. If the drifts were marching across the surface, even 1 cm per year, I would expect to see more buried rocks or wind sculpting of drift around rocks. Pancams might prove me wrong. But I think this shows the big drifts are fairly static on thousand year time scales.

Is there a significant risk of getting stuck if Oppy rolls over one of these rocks? I'd say no. This is the reverse of the situation Spirit is in where LACK of traction is the problem. Here we have abundant traction. Remember the rovers were designed with an eye toward the only ground observations of Mars we had until that time -- the Viking and Pathfinder sites. And as we all recall those sites consisted of scattered fractured rock as far as the eye could see. It's why they tested the rovers at a site in Death Valley California known as "Mars Hill" (see attached image) which consists of an extreme swath of fractured basalt. This debris field that Opportunity is approaching is ideal for the MERs, however I have no doubt that the approach will be cautious nonetheless. -------------------- If Occam had heard my theory, things would be very different now.

That's right, and they're pretty small rocks too for the most part.

Is that the reason this crater is believed to be only about 1,000 years old?

... I think this shows the big drifts are fairly static on thousand year time scales. ...or that the crater is less than 1000 years old. It's all relative and I have yet to see any data that pins any of the relationships down to an absolute. -------------------- If Occam had heard my theory, things would be very different now.
