Thought this deserved a new thread- we can't talk about EVERY LRO target in the one thread
I made a mistake in this one - I didn't include the thruster plume guards. My MER/MPF simulation for HiRISE seemed to come out about right - so fingers crossed that this will be there or there abouts as well. Still in a comissioning phase, something of a slant angle - I'd expect approx 1.5m/pixel if it's at the 120km figure mentioned earlier. |

Nice images! The dark spot puzzles me because it doesn't seem to move with changing sun height, so it is on the surface, but there is absolutely nothing there in the images from the LM window after EVA 2. I have wondered if it was a bit of material thrown there during the LM liftoff, though usually when we see that it is bright, not dark (e.g around Apollo 11 in LRO images).

Phil The "dark spot" only shows up clearly in high sun angle NAC images, suggesting that it's simly rougher soil that doesn't reflect as much sunlight directly upwards as the surrounding area (same as with astronauts' foot tracks and other disturbed soil areas (however, the roughness in this case might be completely natural)). This roughness and the effect it produces wouldn't be obvious from a shallow-angle Apollo photo from the LM. These are all just my musings, of course, based on what I see in the images. -------------------- Curiosity rover panoramas: http://www.facebook.com/CuriosityRoverPanoramas
