Celebrating India’s 2nd National Space Day: Releasing the Lunar Data Explorer On the occasion of the second anniversary of India’s historic lunar landing, I’m excited to present a cloud-optimized Lunar Data Explorer.

India rightfully declared the day Chandrayaan-3 touched down at Shiv-Shakti Point as “National Space Day” for posterity (...) I’m excited to release a Cloud-optimized Lunar Data Explorer.

IM‑2 Athena: An Almost‑Successful South Polar Landing — Intuitive Machines Mission 2

My story on the recent Athena lunar mission

🚨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)

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 more detailed technical analysis, including debris mapping and trajectory implications, will be shared in an upcoming blog post, adding to my existing blog post that wrote early this year.

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.

A week later, on June 12, 2025, India's #Chandrayaan2 orbiter captured two images of the crash site using its Orbiter High-Resolution Camera (OHRC) during two separate passes—at 20:31 UTC and 22:29 UTC.

#NISAR separation from GSLV-F16 today. NASA confirms signal acquisition, solar panels deployed.

How it started vs How’s it going via x/ISROSpaceflight

NASA 🤝 ISRO

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.

ispace 'RESILIENCE' is now as up above the Moon's surface as Chandrayaan-2 oribiter and not so long now when it descends to the Sea of Cold ~(60.5, -4.5)

Image credts: ispace

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.

The first German women in orbit, and the most exotic trajectory - except for those goimg to the Moon, of course - to date actually. Now let's see how much we're going to see and hear in the coming days; a ham radio contact is already planned for 7:28 UTC today: scicomm.xyz/@ARISS_Intl@...
