Here're the latest navcam pictures taken during sol 1850: http://nasa.exploratorium.edu/mars/spirit/navcam/2009-03-18/
Spirit is no longer stuck, but I think the attempt to go on top of HP via the NE path is finished and we are going to the West Valley. A pancam mosaic of the western route is planned for tosol. |

Phew! It's not just me then! A few times I've looked at them and thought "But if that colour is meant to be rocky, how come it doesn't look rocky on the pictures?" then thought maybe I was just being dumb and missing something slap-across-the-face obvious or just not interpreting the images correctly. But for some time now I've been thinking that - and I mean absolutely no disrespect here to the people who spend so much time working so hard on making them - these "terrain mapping" images are now a little bit irrelevent, especially when it's stated that the colours don't actually represent any ground truth.

these "terrain mapping" images are now a little bit irrelevent, especially when it's stated that the colours don't actually represent any ground truth. Colors can only mean one position has the same relative brightness and the same variance as an other position with the same color, there is absolutely no way they can say anything more be course that information simply is not in the HiRISE data. CRISM and THEMIS tell you a LOT more about the surface, but both have a resolution which is far and far less then what we need here, so you can't use them in this case. I gave it a try to see if there was any way we could get any information from HiRISE when working on this small scale but I was already very skeptical about it, it was a nice exercise in chasing ghosts |

it was a nice exercise in chasing ghosts It was definitely worth a try, yep! Not taking anything away from the effort or intentions. I think we can leave those particular ghosts alone now tho, and just enjoy the spectacular real views Speaking of which, hoping we're soon going to get a second look at my very favourite martian rock, McKay (lower right), last seen around Sol 747... -------------------- |
