Wow - lots of chunks smile.gif

I think somebody flushed the toilet on Opportunity - we're getting a LOT of pancam imagery from Sol 114. Imagery that was taken in MAY!!!

I guess being out of the crater really opens up the UHF passes for a full horizon to horizon pass every time - 15 minutes of 256kbits (190Mbits+ ) - instead of just the top 120 degrees or so when you're in a crater smile.gif

From the long range images of it - it didnt seem to "look" too badly damaged, now were seeing it up close it looks much worse lol. And that must have been a looooooooong drive on sol 324. biggrin.gif

There you go ladies wink.gif

I've labelled the big bits so we can sing from the same song sheet. I'd suspect that they'd like to look at A for the science of the imapct, and almost certainly E because it'll be a nice piece of heatsheild detached from the danger zone near C and D

I think C/D will be avoided like the plague - too much chance for danger - but when we get the R navcam frame for the middle of that mosaic - I think we'll see that B is 5 - 10m further away than C/D. If they're happy to look at B -then I think we'll see A - B - then possibly E - or just leave after B. But - like the Parachute and backshell - C/D has too much potential to hurt the rover - it's got to be 2m tall

For scale - from A to E is about 38 metres - and Eagle Crater was about the size of the gap between B and E

Could the object you labeled C in your picture actually be a rock?

This is one mangled piece of metal. When I look at a picture of the original heatshield I can't say that I recognize any piece we see here... unsure.gif Can someone identify the part(s)? And Doug, I think Sunspot is right. Chunks C and E look like rocks.

Now where did that BIG trench go dry.gif

How can it be bended and folded like that without digging a deeper hole in the ground?

Did it land on a rock on the ground perhaps?

Here's the pancam image of the hole :

It's probably deeper than it looks, we're not close enough to get a look at it

So it jumped out of the impact hole and did not make a "genesis" impact biggrin.gif

Well then the hole is free to study, great cool.gif

When I was refering to C and D - I meant the two parts of that central lump which pancam has resolved into being one lump. I'm shifting the naming of D to be whatever piece of heatsheilf is behind C - and keeping it upright.

That piece way out at E really is a bit of heatsheilf. Colour images show that -



Apart from, you know, LOADS of bits of heatshielf - we can see three springs that pushed the heatsheild away from the backshell as well. There's three more out there somewhere wink.gif

BIG picture





In there is a tiny pic of one of those brackets that held the springs pre launch

It'd make a LOT of sense to approach that rock - it's a nice size for IDD work.

Park there - and IDD the rock whilst Pancaming the heatshield smile.gif

These rocks seem to attract Crap from Outer Space.

As you all remember, Oppy just about hit a similar rock just before bouncing into the Eagle
crater. And we haven't seen one like it for hundreds of metres.
