I figured it was time to begin a thread like this, especially since some of us may still be looking for the Surveyor III retro motor casing (assuming the bright dot to the north of the landing site isn't it).
We ought to be seeing some of the other Surveyors fairly soon, I would think. We know most of their locations pretty accurately. Again, I think there is a lot to be gained, both from scientific and engineering standpoints, from detailed imaging of the Surveyor VII landing site, just to mention one. And I really want to see how visible the Lunakhod tracks are as opposed to the MET and LRV tracks. So... until we begin to see images of other unmanned hardware (or the craters caused by same), we could always discuss comparisons of Surveyor III surface imagery to the new LROC images of its landing site here. I'm especially taken by how you can resolve many of the blocks in Block Crater in the LROC image, which gives you a good feel for the explosive nature of the ejecta and roughly where in the ejecta plume a given block might have come from. Might be interesting/useful to apply this information to the samples taken at that location. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

More of a one-fer, I'm afraid. Now I'm afraid to open my mouth.
However, others add more info... Check out this link at the Vernadsky Institute: http://www.planetology.ru/panoramas/lunokh...anguage=english ... where Sasha Basilevsky has posted the discovery of Lunokhod 1 and Luna 17. That's a much bigger deal than Lunokhod 2 (plus it happens to be correct). I have the full image and I'll post details soon. Tracks are barely visible, unlike those of Lunokhod 2, but that may vary with lighting. However I can see tracks in some cases, especially near the biggest crater. I would not have found this by my preferred method, comparing the old Soviet maps with this, because my main feature, the biggest crater, isn't visible in this view. It must be very subdued and only visible under very low lighting. Phil -------------------- ... because the Solar System ain't gonna map itself.

. where Sasha Basilevsky has posted the discovery of Lunokhod 1 and Luna 17. That's great news Phil! On the Soviet side of things, that leaves Luna 16 and Luna 18, both of whom I expect will be discovered in the near future. And offcourse the big price, finding Luna 9 and 13, which will be very very hard given the small size of the landers and the large uncertainty in their positions, but who knows... I still have the impression that Luna 23 is standing at a very large tilt, possibly with one of two of its legs in the crater or on top of some boulder. Given the size of that lander (which includes the ascent stage) the length of the shadow doesn't seem to add up and sun reflections are very different from Luna 24 which is seen under the same sun angle. An extreme tilt might have disabled the drill and/or the firing of the ascent stage. |
