Yes, another great view of Luna 20 with a different MZ photo strip. This one is quite clear.

Great shot of Jules' crater below Luna 20.



Still looking for dark formations as a tell.



These dark formations are above Luna 20 and near left side of photo strip.

I believe the photograph may be inverted as the bright crater is most likely the one Thing pointed out and another aspect of a previous photograph of a dark formation that may be Luna 18. This dark formation is better defined now. Others I pointed out in earlier photographs did not appear in this strip- or I just simply missed them  :)

Revisiting Luna 18 targets again.  Luna 20 below.

The NAC photo strip really is quite good.

http://wms.lroc.asu.edu/lroc/view_lroc/LRO-L-LROC-2-EDR-V1.0/M111219210LE

I grabbed some pictures of the possible crash sites we have been discussing off the strip and lightened them a bit to show better detail.

Jules' crater and possible impact site:





Possible impact site or dark halo-like crater:





Luna 20 again at same approximate altitude as the other targets.





Very intriguing possible crash site below.  Looks like the item impacted showing some minor ejecta. From my understanding of Luna 18 it was on course for a controlled landing and not a planned maximum speed impact for seismic monitoring like the Apollo ascent stages.  So, its terminal impact velocity may have been significantly lower.  Maybe Thing or other forum members can shed more light on this topic.   

This is the same target Thing and I discussed earlier in this thread- http://www.moonzoo.org/examine/AMZ100266z  Photo in link is inverted from NAC strip and target is above and to right of fresh white crater.  Below is NAC photo strip grab.



This last photo really may show Luna 18 below and to the right of the fresh white crater.  Looking forward to hearing a determination from the MZ team.  Please feel free to jump in with your comments pro and con as we are all learning together  :)

Thought it may be insightful to put Luna 20 and the possible Luna 18 photographs side by side for comparison.  I resized the Luna 18 crash site target by a factor of 2.  As speculated in the previous post, the photograph shows Luna 18 imbedded in the lunar regolith with possibly the ascent stage (still attached) being featured.  If my very rough calculations are correct, the separation distance between the two targets is under 2 NM.

Oh my Gawwwwwddd, I searched for hours having this picture

to ensure myself that little black thing on left edge that I ignored several times  >:( >:( >:( actually IS Luna 20:

ID: AMZ1001hp6
Latitude: 3.78897°
Longitude: 56.6256°
Sun Angle: -32.35°

Not impressive, but we now know that spacecraft can look like this too, especially on low contrast strips.

Now, I call everyone to find Luna 18!

It crashed only 1.3 km from the 20, but on LROC site they still not sure 'bout the coordinates. Lets together search some strips:
M104147428L
M108862844RE
M104147428LE


I found this which matches Things picture which isn't a ACT-REACT FIND

it's identical and can be found here http://www.nasa.gov/mission_pages/LRO/multimedia/lroimages/lroc-20100316-luna.html
