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

I agree that Phil's object is Luna 18. Geert's object looks like a rock which is a different shape and substantially smaller than a Luna. Geert, thnanks also for explaining how there are more images available than the system seems to show, which also explains how no-one (to my knowledge) has been able to find Luna 16 in a big context image, although the craft itself has been excised and posted by the LROC people.
If south is to the bottom, the ascent stage might actually have toppled over to the SE, and there is a curious extra shadow on the NE side of the image.. a rock or an arm or antenna of the spacecraft? Better defintion image awaited with interest. |

Better defintion image awaited with interest. The object I mentioned before was at the coordinates the LROC site gave for Luna 18, so it's no 'Geert's object' ![]() I agree that the object Phil shows much better conforms to size and shape of a Luna sample return craft, so I think he has indeed a much better candidate. I tried to find the object Phil mentions in other images of the area, problem is making sure that you have indeed the same thing, but maybe I succeeded in M104147428LE, if I'm correct than the same crater Phil mentions is in this image almost at the bottom of the image. Might this be the same object Phil has found? It certainly looks 'artificial' and indeed as if the ascent stage has broken off, there still seem to be some shadows of antenna.. EDIT: From the latest localizer image Phil posted, it's clear I had the correct crater, but the wrong stone/object ! Still trying to find the correct object in the other images of the area. I'm trying to get the same thing in other images as well, and trying to work out convincingly that we are indeed talking about the same thing, it's hard to puzzle out how pixel-coordinates from one image map into the other, so I might very well be wrong! If I can find the time I'll try to work out a better method of making sure we are talking about the same thing.. |
