🚨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)

🚨 (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)

With launch successful, ISRO waits until it starts receiving and processing 8 Terra Bytes of S-Band data and @nasajpl.bsky.social 35 Terra Bytes of L-Band data single a day! Now that’s wealth of global data

ISRO successfully launched and deployed NISAR in its intended orbit with a precision of ~2km to its desired placement.

A day after the launch of ispace 'RESILIENCE' ISRO seems to have already started terrain analysis on the landing location using the highest resolition camera circling around the moon right now, Chandrayaan 2. Image shows the latest released images of the target landing location of RESILIENCE.

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! here's the processed image. #WhatYaokiSee Credits: Daimon/C.Tungathurthi

A more non-oblique look at #IM2 Athena. This view you can clearly see the shadow casted by Athena.

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.

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. There are other smaller PSR's within the 3Km radius and the next...(1/3)

We made it to the Moon! Blue Ghost is currently orbiting our nearest celestial neighbor! 🌖 It’s truly unbelievable to see our lander finally in orbit around the thing I’ve been looking at in the night sky for 35 years. I can’t wait to get the chance to stick the landing in a few weeks!🧪

ISRO aborted its third #SpaDex attempt at 3m separation, just before the final docking. They have been brought back to a safe distance of around 4.5 Km now. No new dates has been announced.

Chandra (tckb) @moonandbeyond.blog · 12/01/2025

#SoaDex crafts are 15m now, next up 3m then final docking. The final docking is expected to be in about an hour when it’s visible over India. There will not any live streaming but I expect a docking video on successful completion

Chandra (tckb) @moonandbeyond.blog · 11/01/2025

#SpaDex update. Spacecrafts are about 230m apart and likely closing in for next stages of 15 and 3 meters before they start final docking sequence. Docking expected to happen tomorrow with very slim to no chance of live streaming. I expect an announcement with a docking video, well hopefully🤞🏻
