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. smile.gif

Thanks for the tip!

I'm learning a lot here. Locating both those landers on that image, I find that they are further north than I had expected. Also, that raw image is south-up. If it's rotated 180 degrees it is right-reading - no further flip needed. When I compare the two landers - I mean the candidate Luna 18 lander as it's not confirmed yet - I find the 'Luna 18' is quite a bit smaller than Luna 20:

Maybe it's not the right object, but large rocks are very rare in this region.
