I think it's time for a new topic. We are effectively at the entrance to Gediz Vallis now that we have climbed this last slope on sol 3871.
The previous topic described the Greenheugh Pediment. We made a valiant attempt (two valiant attempts really) to explore its surface. It was too rough for Curiosity's dainty wheels but its outer edge was examined in detail. But now there are new targets: a crater cluster, the Gediz Vallis Ridge whose upper part is accessible from this level, and the large valley and its central sinuous valley as well. I attached a picture seen at LPSC - I am embarrassed to say that I can't remember where it was from. Usually I have detailed notes of sources but this one slipped through. Maybe someone will recognize it and I can add a source. It gives the name of the butte at the western entrance to the valley, annotated onto the JPL map. Phil -------------------- ... because the Solar System ain't gonna map itself.

Yeah, the regular 8x8 green blocks are easy to deal with, and there are some in smooth areas of this image that my algorithm removes, but some areas not on the 8x8 grid remain.
The thumbnail is available here: https://mars.nasa.gov/msl-raw-images/msss/0...870I01_DXXX.jpg and presumably comes from the original raw data. Here it is scaled up 400%, but with no other processing: I think the resolution is too low too say for sure. The image has an overall greenish cast which should go away with calibration so the bright areas may still be close to white. |
