Finally, some high-quality photos from Chang'e 3!

EDITED JANUARY 13: Three of the images have been replaced as noted below.

Once again, tips from helpful users at nasaspaceflight.com and from Twitter have led me to a new pile of photos from the Chang'e 3 mission. And these are the best-quality ones I've seen yet. Almost all of the images I've seen to date have been shared through a bizarre roundabout method of projecting them on a screen, then filming them with a video camera, then aired on television, and then screen-grabbed. These photos are different: they are clearly direct from the original digital data. They're still not perfect -- they have been downsampled, contrast-enhanced, watermarked, and JPEG-compressed -- but they're so, so much better than what I've seen before, rich with detail and nuanced in color. They were also accompanied by a little bit of information about when they were taken, which is great. Here's the trove of images.

This first one is really special:

The Chang'e 3 lunar lander captured this photo of Earth from the lunar surface on December 25 at 2:15 China time (December 24 at 18:15 UTC).

Note: the Earth image has been replaced with a higher-resolution version since I first posted it.

And these panoramic 360 views around lander and rover are new:

Chang'e 3 captured the images for this panoramic view around the landing site on December 17 and 18, 2013. The images have been mosaicked into a polar azimuthal projection, showing the full 360 degrees of terrain around the lander.

Here, Phil Stooke has "unwrapped" the polar azimuthal view to make a more familiar-looking panorama:

Chang'e 3 captured the images for this panoramic view around the landing site on December 17 and 18, 2013. The original image was in polar azimuthal projection; it has been reprojected into a more familiar landscape view here.

Look, here's some science data! An ultraviolet view of Earth:

The extreme ultraviolet camera on Chang'e 3 studies the plasma environment around Earth at a wavelength of 63 nanometers. This image was taken shortly after Chang'e 3's landing, on December 16, 2013.

Note: the ultraviolet "image" that I had originally posted was a computer simulation. The image above is actual data.

We've seen these descent images before, but the detail is really nice here:

And finally, some lovely colorful landscape shots around the lander, of the rover, and images of the lander from the rover's survey.

This photo from the Chang'e 3 lander confirmed the safe deploy of the Yutu rover on the lunar surface at 23:41 China time (17:41 UTC) on December 15, 2013.

By December 21, Yutu had completed a semicircular traverse around the lander and was able to view its "front" (south-facing) side.

I got most of the images from this slideshow. I don't recommend following that link, because the photo site also contains other photos I'd rather not have seen. I got the ultraviolet image from another slideshow that contained most of the same photos as the first slideshow, but at much worse JPEG compression.

The Sun should have risen at the landing site by now. Time to wake up, Chang'e 3!
