Thank you for letting us see that.

The slide from the video showed the view of the lander that we have already seen as well as the two new ones. When I compare them... it looks like the object on the horizon of the rocks stereo image is the top of the lander, just visible over a small local rise in the terrain.

And here I was thinking they are just very strange outcrop of rocks. That indeed looks like top of lander, really nice catch.

There's been an addition of around 40 new files at the Chandrayaan-2 OHRC page, and a hefty chunk of them seem to focus on the Chandrayaan-3 lander/rover.

Edit to add: most of the files around the lander site seem to pre-date it, with only this post-landing image to go at so far:

This link is to a very interesting talk by Santosh Vadawale of the Physical Research Lab in Ahmedabad, the PI for the APXS on the Pragyan rover.

It goes from the beginning of discussions about the instrument to flight operations. Among the interesting points, the fixed solar panel on Pragyan plus the motion of the Sun across the sky originally dictated a counterclockwise traverse after deployment. That route was blocked by craters so a 'backwards' path was selected, requiring a 180 degree turn after every drive to charge the battery. Also a map of locations of the APXS measurements (of which more later). The hop at the end of the lunar day was preceded by a short test burn.

About the APXS map. Here it is, superimposed on the earlier ISRO map. There are multiple points of disagreement. We can say that the definitive map is not yet available. One thing that will help will be a post-mission OHRC image which might show the rover and clarify its location. The lander location is more accurate on the APXS map.

Shan Subramanian has tweeted this LRO image:

I compared it with the OHRC image used as a background to the rover traverse map. There seems to be a feature casting a shadow like the lander but smaller and not present in older images. It is close to where the previous maps placed Pragyan so it is probably the rover.
