Wonderful images! Great detail. But in your opinion, just how "true" are these 3D images? How much are they "manipulated'?
Another good job. (You're so routine at doing an outstanding job that to save typing time I may have to shorten "great job" to just "GJ" )
What is the data release plan for KAGUYA?
One year after the end of the nominal operation phase (about two years after the launch), all KAGUYA products will be opened for public access online. During this one year data study period for instrument teams’ data research and validation / verification, sample data will be posted on the homepage for public outreach.

Subject Re: [SEL_HP:00688] Concerning the KAGUYA Mission
Thank you for your message. About KAGUYA product, we plan to open all KAGUYA
products one year after the end of nominal operation (two year after the
launch). Before that,
we only posted sample images visualized from KAGUYA products on the Web
we have to protect our mission instrument teams right to study in prior
to other scientists (first author right).
Thank you for your understanding.
Outline of instrument
A germanium semiconductor crystal cooled to below -180 degrees centigrade by a Stirling cryocooler is employed as a main detector of GRS. GRS has an excellent energy resolution 20 times superior to those used in past lunar missions. Thus, GRS can discriminate the incident gamma-ray energies with high precision and can determine abundances of more than 10 elements in the lunar surface.

It's a good picture. High quality it seems. Let's just hope that there are many more to come.
I thought it would take them longer to put anything out, but I guess they were in a hurry to show that they could do it.

Some more stuff from China's Chang'e today, including a 3D image:
BEIJING (Reuters) - China has dismissed Internet gossip that its first photo of the moon taken from a lunar orbiter might have been plagiarised from NASA, local media said on Monday.
The country launched its first lunar probe, the Chang'e 1, in October and released a photo featuring a patch of grey moon surface splotched with craters last week, hailing the mission as a "complete success".
But some Chinese Internet users have questioned its originality after comparing it with an almost identical lunar image from the U.S. National Aeronautics and Space Administration in 2005.
"There is absolutely no forgery," Ouyang Ziyuan, chief scientist for the lunar probe, told the Beijing News.
The Chinese and U.S. lunar images looked similar only because they had aimed at the same area of the moon's southern hemisphere, Ouyang was quoted as saying.
"But a careful examination will tell some small differences," Ouyang said.
There were two craters on a certain spot of the Chinese photo, but there was only one on that same spot of the American picture, the Beijing News quoted him as saying.

Interesting pictures, internos. As usual. You're too good for us mere mortals.
But why is there so little difference between the pictures, except for the new crater? I realize it could have been a new strike since the last set of photos, but it would seem odd that the orbiter taking the photos would be so close to the original.
This past week has given me confirmation of something that has been a growing dread and suspicion by many of us in the space community regarding our latest return to the Moon effort. The Vision for Space Exploration (VSE) is being suffocated. It is literally having the life choked out of it.
The vision is simple, a prosperous world of 9.5 billion people in the year 2050 and in 2100. This world will have a large middle class in India, China, Europe, Japan, as well as the United States. The people of the rest of the world have a legitimate right to the same standard of living that we enjoy here in the U.S. today. However, it is clear that the resources of our little planet are inadequate to provide this level of civilization. A few years ago the World Wildlife Federation put out a press release that our global civilization would need the equivalent of two more Earths in order to provide for all of the people that will be alive in the year 2050. In fact we have thousands of worlds in our solar system that are worth untold trillions of dollars that can be developed to provide these resources for our use here on the Earth.
In the book "Guns, Germs, & Steel", the author, Jared Diamond developed the theory that all civilizations are ultimately limited by the resources at their command. This is what led to cannibalism in the pacific islands, the lack of metal technology in New Guinea, Australia, and South America, and conversely the plentiful nature of these resources gave western civilization its head start leading to the current world system. It is my feeling that a prosperous world that is far above our level of civilization in the year 2100 is both a desirable state and an amazing legacy for America to bequeath to our fellow planetary citizens. This is also a vision that will connect with the American people.
Since our victory in the cold war our dreams have been small and we as a people have done nothing but fight each other. It is time for that to end, it is time for us to rise above our differences, and space is the place for that to happen.
The Japan Aerospace Exploration Agency (JAXA) verified the Spectral Profiler (SP) onboard the lunar explorer "KAGUYA" (SELENE) orbiting approximately 100 km above the lunar surface, through initial observations on November 3, 2007, and subsequent data analysis. The obtained data is the world's first continuous reflectance spectra of the far side of the Moon in the visible and near infrared region.
The satellite was confirmed to be in good health through telemetry data received at the Usuda Deep Space Center.
These two figures are visualized images produced from SP data normalized at 600 nm with a simple correction to the variation of the overall reflectance of the lunar surface and SP detectors response.
The horizontal X axis of the right figure shows wavelength (600nm-1680nm) and vertical Y axis shows longitude (S19-53 degree - 1000km).
The red part shows relative strong reflectance, while yellow, green and blue show weaker reflectance than the red area, respectively. The color change from green to yellow at around 950nm is expected to correspond with iron-bearing mineral distribution.
The pink part on the right figure of the MI data shows the line profiling with SP observation area. SP data is expected to show that fresh rock and soil exist in a small crater or on the slope of a large crater since the color of the profile is longer than 600nm and has changed from yellow-green to blue or black (reflectance of the location is weak in longer wavelengths). However, the other area is experiencing space weathering since the color changed from yellow-green to yellow or red (reflectance of the location is strong).
