To answer Ustrax's querries from the other thread, I think we can now see more of the
The leftmost (Endeavour north rim) and middle (far rim) features look similar. But it looks like we can see more stuff on the right, which is Endeavour south rim and Iazu. The view we had a few sols ago (2133) of Iazu was still partly obscured by dunes, so it makes sense that we can see more now. I can't see Bopolu in the navcams, though it could be there and buried in the jpeg noise... |

The heading is consistent with the next crater on the planned route. Early in this thread I suggested based on the navcams that this feature to the south was the hill far to the south. I agree it looks much too close to be that hill, which is farther than Iazu. But I'm not sure about your identification, Tesheiner. I'll call the close pair of craters you suggested Twin Craters (I guess they're not identical twins!). Measuring the angles each component (A and B ) would subtend at Conception, I find the Twins should look this big: In other words, much bigger than the dark feature on the horizon. But looking closely, there are some dark features (black arrows) that could perhaps be one or both of Twin Craters somewhat closer than the horizon. In L2, these features look bright, which might be exposed bedrock on the rims? Is there another feature somewhat farther than Twin Craters that the dark feature on the horizon could be? |

We will certainly have to keep an eye on those features once we leave this area.
Fredk is right. Althought the horizon feature is at the right heading, it's too small to be the twin craters; those ones, combined, cover about 3.5º viewed from the current position, while the black feature has only 0.4º. Is there another feature somewhat farther than Twin Craters that the dark feature on the horizon could be? Unfortunately, the HiRISE picture I'm using doesn't cover that area. |
