We've been talking about this as if we had overestimated the height of Cape York (and we had), but now it looks as if we had underestimated the steepness of the slope down into Endeavour.

You really feel like you are looking into the bowl of a crater here:

QUOTE (Phil Stooke @ Jul 30 2011, 07:10 PM)  it looks as if we had underestimated the steepness of the slope down into Endeavour. I estimated slopes of 5 or 6 degrees in Botany Bay based on pgrindrod's contour map, which still looks realistic. If we were looking down a 5.5 degree slope, the slope would appear this far below the distant (true) horizon in pancam:
So there's still a lot of room for the horizon to drop. My guess is in another few hundred metres, once we get a clear view down the throat of Botany Bay, the view will be really impressive (without Philovision!), and CY will actually turn out to be quite a dramatic "shelf". I hesitate saying all this since I could be wrong! The view will depend on what the slope does beyond CY. Anyway, we'll soon see... |

Here is the colourized version of that image for
better viewing of the slope. jan van driel

For those of you not following me on Twitter two bits of news: Another ~65m drive tosol and that large ripple/dune/mound has been named 'Pathfinder Mound'

Note that the "grain" of the cracks in the sediment now trend parallel to the rim of the crater. The boundaries of the covered-versus-uncovered areas also shows this trend. More extension perpendicular to the rim? Influence of buried topography? We are probably descending thought sediment layers too. The ground slope here is only 1-2 degrees. So far.

"Data dropouts," meaning... what do you mean?  Combination of a few factors... 1) going into Restricted planning mode (as we do every couple weeks) 2) as it seems to me, smaller available relay downlink volumes through ODY and MRO (this is just bad luck, and perhaps there's some selection bias in my estimation) 3) longer latencies in the relayed downlink (again, bad luck) 4) dragons Mostly the dragons. Mostly. Though, again, it depends what you mean by "dropouts". |

Hi Matt!
I think he meant these black parts like here: http://marsrovers.jpl.nasa.gov/gallery/all...IP2375R2M7.HTML These parts just haven't been not been received on earth, and will be later send again. -------------------- Need more input ...

Ohhh, that kind of dropout. Yup. It's a function of how they choose to prioritize the images and any sub-framing they do. |

Okay, this was already amazing. But now, this is going to be epic.
Sol 2671 pancam view  Also navcam, same sol :  Cape York is now obviously visible on the left part of the pan. I just can't believe what we are living now  .Ps : I will be a little bit out of networks the next week. I will try to continue working on pictures but not sure (internet through 3G network, in the Alps, it can be a little bit random). -------------------- |
