QUOTE (Tesheiner @ Jan 20 2006, 05:38 AM) It was already said that those structures seen on previous hazcam pics (well, in all sort of cameras and filters...) were delicate. [attachment=3535:attachment] (138k) But what about these ones? It looks like the smallest touch could broke them. [attachment=3536:attachment] (138k) PS: It's time to open a new thread, don't you think so? Good idea. That topic was "tired" and had the cord showing. Delicate, to be sure. One thing I've noticed is that the "ledge-forming" rocks are a layer and extend to the right and left of where we camped out. I wonder if that feature is related to the bluff at Mogollon Rim? We need to check out the "mobile dust" at that site and see if there has been more movement during the stopover. --Bill -------------------- |

Also since this site a only a couple of degrees South of the equator there is not much difference between the mid-summer and mid-winter altitude of the Sun (62 and 68 degrees, respectively) so it might seem that a north-facing slope isn't critical. But given that these angles represent a loss of 47% and 37% based on ther cosine function, it might require some north-facing slopes to increase the solar incidence on the solar panels.
The big problem is the orbital eccentricity. Mars is some 19% farther from the Sun in the Martian Southern Winter (which we are approaching) so the sunlight will be less intense by xx% so some time on a north-facing slope may be needed to top up the batteries. --Bill -------------------- |
