Lunar Programme To Be Open To World
Although China is still in the "initial stage" in tapping the moon and outer space when compared with the United States, Russia and Europe, the nation is catching up, Luan said. http://www.spacedaily.com/dragonspace.html The first phase of the Chang'e Project was solely accomplished by China through its own technology, products and designs, said Luan, former director of the China National Space Administration (CNSA). However, lunar scientists from Europe, the United States and Russia have expressed their willingness to co-operate with China in its research of the moon and deep space exploration, he said. Chinese scientists are assembling, integrating and testing to ensure that the mission of the nation's first lunar explorer, Chang'e-1, goes smoothly, a top space official said yesterday. http://english.people.com.cn/200607/26/eng...726_286707.html "Fundamental development has been achieved in all five related systems ranging from the satellite, the rocket, tracking and control, ground applications and the launch centre since it was approved two years ago," said Sun Laiyan, head of the China National Space Administration. The lunar orbiter is scheduled to blast off next year from the Xichang Satellite Launch Centre in Southwest China's Sichuan Province, Sun said at the ongoing eighth International Lunar Exploration Working Group (ILEWG) Conference in Beijing. The spacecraft will be 2350 kilograms in weight. According to the plan, the program will go through four phases. 1. Send a satellite to orbit the Moon 2. Conduct exploration on the surface of the moon through the soft landing of a detector. 3. Collect Moon surface samples using a robot, which will then return to the Earth. 4. Manned missions. http://en.wikipedia.org/wiki/Chang'e_program According to the schedule, detailed program design of the first step will be completed by September 2004. Research and development of a prototype probe and relevant testing of the probe will be finished before the end of 2005. Design, manufacture, general assembly, test and ground experiments of the lunar probe satellite will be finished before December 2006. In 2007 the Chang'e 1 will blast off. |

Also, what NASA spacecraft would have taken a picture in 2005? Perhaps they refer to a Clementine mosaic released in 2005 -- is that it? I think that they are in fact showing part of the Clementine base map.
Here is an original Clementine image (not from the base map) of the same area. It's a 750 nm UVVIS image. (Source) The Telegraph article showed a crop from a low-res version of the Chang'e image. Here is a crop from the full-res Chang'e image, which does indeed seem to show a new feature in the position highlighted in the article. What do you think, Phil? A closeup on the area: My two cents: look how much more detail is visible in the Chang'e image, even though they are at similar resolutions, and even though the Chang'e image has been JPEG-compressed, while the Clementine one is original data presented in GIF format, so it's losslessly compressed... --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

It is clearly a double image of the same crater, caused by improper assembly of the mosaic - this is common on early releases in a mission.. On the new image, you may notice that the crater within the crater on the left side is visible, just as in the Clementine image, but the crater abruptly fades out to the right. On the "upper crater" in China's new image, the crater fades out at about the same place horizontally in the image, which in this case is on the left side. If you look at the little crater along the rim at the 2:00 position, it is in exactly the same place in both images. Looking below the crater, you will also notice the slightly diagonal (close to vertical) little trough visible in the Clementine image is also double.
