🚨I found the ill-fated @Int_Machines #IM2 #Athena lander using the #Chandrayaan2 OHRC and it shows some interesting patterns around the site where it hard landed. Exclusive story 👇 and I’ll share more detailed observations and my thoughts on this soon in my blog. (More pictures are storely below)

When comparing OHRC imagery from #Chandrayaan2 with
@LROC images, it’s clear once again that @isro
’s OHRC remains the most capable lunar observation camera to date—delivering unmatched clarity, resolution, and detail from orbit.

A distinct light-toned halo around the site indicates lunar regolith was ejected during impact. The debris spread extends noticeably from the point of contact, hinting at the significant kinetic force involved in the crash.

Both images offer high-resolution visuals of the impact site. In the first annotated image, the crash point is clearly visible, along with a debris field scattered around the site, providing valuable post-impact data.

The exact coordinates of the impact, as determined from OHRC imagery, are (60.445897, 355.410438). OHRC captured these images from an altitude of ~109 km, with a pixel resolution of 28 cm—some of the clearest views to date.

🚨 (New High res lunar images) On June 5, 2025, ispace_inc’s HAKUTO-R lander attempted a soft landing on the Moon in the Mare Frigoris region. Unfortunately, the mission ended in a crash landing during its final descent. (1/n)

Now that’s wealth of global data

this is kinda hard to tell with very limited public info. But, this is what I can interpret it. The Yaoki rover is completely hidden, but you can see the shadow as well as the illuminated regolith on the top left corner.

The tiny rover on board #IM2 Athena captured the broken leg of Athena (again!) and a mysterious debris off the lander. @yaoki_space has released the raw images - thanks!

First images of @Int_Machines #IM2 Athena from
@LRO_NASA Athena did land in a tiny crater than I originally imagined. Its more up north than the low illuminated areas I originally thought.
Athena is at 84.7906° S, 29.1957°E but there is a minor small uncertainty in that location.

Average Solar illumination and Earth Visibility seems pretty good as long as #IM2 Athena kept with-in intended target location. Given the 😶🙃 I speculate Athena went far off its target and toppled - whatever that means this time on

Here's my initial assessment of Intuitive Machines’ IM-2 mission Athena Landing site. There are at least 2 significant PSR's (<1Km2) (PSR1, PSR2 ) within 3km radius around the planned -84.78°, 29.13°E target landing site.
