This image is my poster for the 2026 Lunar and Planetary Science Conference which I am attending virtually because - you can imagine. It has 8 panels containing text and images, comparing high resolution images of various spacecraft landing sites from LRO's camera (LROC-NAC) and the OHRC camera on India's Chandrayaan 2 orbiter. OHRC images have up to 4 times the resolution of typical recent LROC images because LRO is in a higher orbit than wen it started. The OHRC images show some important details impossible to see with LROC. For SLIM, the LEV-1 hopping rover is probably what is seen by OHRC adjacent to the lander. For Chandrayaan 2, which crashed, the largest fragment is seen by LROC to have left a dark track as it rolled or bounced, but OHRC resolves a line of small pits. For Chandrayaan 3 a paper by Iyer et al. last year showed that OHRC before-after differencing revealed small dark spots where the Pragyan rover made a comm turn after every drive. At IM-2 Athena's site unique gouges in the regolith must have been made by the lander footpads as it touched down twice before falling into a crater.

... I show the new thing: the LEV-1 hopping rover for SLIM, rover turning marks at Chandrayaan 3, a row of bounce pits for Chandrayaan 2, the remarkable footpad gouges at IM-2 Athena's site. I point out that the new imaging service from Firefly, Ocula, will […]

Slight change of plan - tomorrow the lunar site selection begins. Today, a preview of my LPSC poster. I compare LROC-NAC and OHRC images of some landing sites - OHRC has 4x the resolution of typical LROC-NAC images at the moment. At first NAC had a resolution of 50 cm/pixel from 50 km but now it […]

This is a very small part of a very large OHRC image showing the double crater (exactly in the middle) made by the upper stage of the rocket used to launch China's Chang'e 5 T-1 spacecraft in 2014.

You can see the LRO images (before and after) at the link in the previous post. What did OHRC show us? Here is the image. The impact feature is the double crater exactly in the middle of this tiny detail of a very large image. Comparison shows it is more […]

In 2022 an object was found on course to hit the Moon. LRO imaged the crater it made:

It was almost certainly the upper stage of the rocket used to launch Chang'e 5 T-1. Chang'e 5 was China's first sample return mission, but Chang'e 5 T-1 was a flight to […]

I have been extolling the virtues of India's Orbiter High Resolution Camera (OHRC) instrument on Chandrayaan 2, so I had the idea of looking to see if any other lander or crash sites might be found. There are surprisingly few images by this camera considering it has been in orbit for 6 years […]

Intuitive Machines have not yet released their analysis of the landing, but this OHRC image has to be a major contribution to that analysis. I have never seen anything like this before but we don't have images like this for most landings. It would be great to have this for Luna 23, for instance […]

A map of the landing site of IM-2 Athena, with comments suggesting what seems to have happened to the lander. The image is from Chandrayaan 2's OHRC instrument. It shows two craters with the lander lying in the southern one. Odd gouges on the northern and southern rims of the northern crater suggest that Athena's footpads scraped the surface as it was moving near-horizontally southwards. I have never seen anything like that elsewhere, but we don't have such great pictures of most landers. It would be great to see this for Luna 23, for instance.

LRO imaged the Athena landing site:

but again the most impressive and informative images were taken by India's Chandrayaan 2 orbiter. Its Orbiter High Resolution Camera (OHRC) took an image and Indian space enthusiast […]

Another example of the embarrassing systemic racism in the Ontarian and Canadian Media and Press. OHRC introduced the 29 point action plan against systemic racism in the education system. Only 1 outlet asked a question. #Shameful

I think its far too easy for me, having intimately worked on finding it. Here'a close up view #Apollo11 Lunar descent module that've compiled a while ago.
