A picture taken on 28 November 2022 at a distance such as the Earth and the Moon had the same apparent size for Danuri's camera.
Contrast increased on the Moon's surface since it appears far much darker than the Earth on the original image. -------------------- |

Very impressive, Mike. Well done!

More from ShadowCam. This is part of a small crater inside a much larger one near the north pole. Check out the full mosaic at the bottom of the page, zoomable or downloadable.

New image from ShadowCam - Marvin crater, which is adjacent to de Gerlache at one end of the 'Connecting Ridge' near the south pole.

The quality of these images is remarkable. It's interesting to see the lighting coming from different directions in different parts of the image.

Another great image from ShadowCam.
https://www.shadowcam.asu.edu/images/1297 This is the central peak of Aristarchus seen by Earthlight. I hadn't thought much about Earthlight imaging before but now I am interested in seeing what some Apollo and other sites would look like.

I hadn't thought much about Earthlight imaging before... When we were developing Shadowcam, we tried to come up with ways of having the TDI be selectable so that we could still image on the dayside, but this was just too complex given the constraints of the electronics. So we always asked about Earthlight images, but the SNRs are much poorer than the dimmest permanently-shadowed regions (which you can see in the graininess of the images.) Still, it's better than nothing and a good indication that the system doesn't do too badly even at very low signal levels. -------------------- Disclaimer: This post is based on public information only.

Sweet! I remember seeing Apollo images of Orientale from lunar orbit in Earthlight, much lower resolution and grainier than this one. Probably in one of the Apollo Preliminary Science Reports (Phil would know).

Not an expert, but I recall looking at prints of Lunar Orbiter images that were of similar resolution to these impressive shots.

John's faith in me is touching.
According to my records, Apollo 13 was intended to image the area around Orientale by Earthshine at the end of its orbital phase (but didn't for obvious reasons). Some experimental Earthshine images of Aristarchus were taken by Apollo 15, followed by sunlit images of the same area later. Apollo 16 took a few images across Riccioli crater late in the mission. Finally, Apollo 17 took quite a few frames from the Luna 9 area out across Orientale. In addition to these images, Earthshine images have also been taken by star-tracker cameras on Clementine and LADEE. I think Lunar Flashlight might have done the same (or perhaps one of the other recent lunar cubesats, RIP) if its mission had gone as intended.

Some nice new images on the Danuri website. A view of the central peak of Tsiolovskiy is particularly dramatic.

Danuri's instrument images are now available for download, though it's a tricky business. Here's a link to the files released so far:
https://www.kari.re.kr/kpds/published/KPLO/...O/PublicRelease As yet there's no map based search, which is a shame as the xml files accompanying the images don't seem to have lat/long data included (at least for LUTI). There is a search facility, but it's difficult and slow to navigate, eg: https://www.kari.re.kr/kpds/search_view/lev...ct?keyword=LUTI Shadowcam data can be searched for here: https://data.ser.asu.edu/lunaserv.html Edited to add: They did release views of Apollo 11 and 17's landing sites here: https://twitter.com/kari2030/status/1706532004945412205 The Shadowcam has also coverd Apollo 14, 15 and part of Taurus-Littrow under Earthshine conditions. |
