Oh, WOW. Those were a real trip; very, very impressive!

two papers (in Chinese, unfort.) on Chang'e 1 have been released in the Chinese Journal of Space Science

These are all really awesome, thanks! Has there been any more news on the planned landing for 2013? You know, sometimes I wonder why China, India, Russia, Europe, Brazil? etc. are undertaking all these expensive lunar missions...I mean its not like there's isnt already a lot of data out there from NASA and ESA. Do those countries just want their own set of data, but why? Is it a matter of trust? Or a matter of pride and accomplishment? A matter of "owning a piece of the moon"? I know, everyone tells us we live in the global age, bilateral and multilateral agreements, etc etc. But it makes you wonder if all the data gets shared freely or not.... Sorry if this is drifting off into politics.

It's about mastering the technology in preparation for bigger things in the future.
The landing in 2013 appears to be on track. A lander with a rover will land in Sinus Iridum. In about 2014 or 2015 a second lander and rover, perhaps with more autonomy, will land at another site. Then in about 2017 a sample return mission will be flown, and a year or two later a second sample return. That much is established, but human missions are being considered for about 2025 or slightly later. Phil -------------------- ... because the Solar System ain't gonna map itself.

China announces the end of the Chang'e mission. Still no word of a possible extended mission in solar orbit

... or either of the other possible extended missions which have been discussed: return to Earth orbit or extended lunar operations ending in impact. The latter looks more likely to me.

of course an impact is more likely, but a solar mission would give them some experience in navigating and most of all communicating with a truly deep space probe. and that would be invaluable for Yinghuo when it reaches Mars next year.

True, but at the cost of additional lunar science.
You're right of course that the solar orbit option was mentioned, but so were the other two options. No word yet on which one will actually be used. There's also no word on whether or not the previously described impact probe on Chang-E 2 even exists. Phil -------------------- ... because the Solar System ain't gonna map itself.

Chang'e 2 may depart lunar orbit on June 16 for L2.

My [perhaps uninformed] question is how will they communicate with the spacecraft? Article on Emily's blog: http://www.planetary.org/blog/article/00003037/ |

L2 is not a point - it's a broad region, and the spacecraft orbit loosely around it, almost never hidden by the Moon. Right now NASA's ARTEMIS mission has two spacecraft, one orbiting L1 and one orbiting L2, waiting to go into lunar orbit in a few months for particles and fields studies.

QUOTE In any case no images at all have ever been released from Chang'e 2 so even their quality is unknown. Several images are here. -------------------- -- Hungry4info (Sirius_Alpha)
