A stretched out version - easier to try to locate it. But I don't recognize the area. This has north up, from the lighting direction, if it's taken on the last orbit.

This Aviation Week article http://www.aviationweek.com/aw/generic/sto...china092809.xml is mostly about MSF, but it does say that Chang'e 2 will fly in October 2010.
"Improvements include a better camera with a resolution of 5 meters (16.4 ft.) at the surface, they say."

Novosti-Kosmonavtiki confirms launch in October 2010 and it is also said that Chang'e 2 will be 100 kms closer to the lunar surface. It's also said that the instruments will be even more sophisticated and powerful, but I don't know about the resolution of the camera.

Chang'e 2 will be based on a back-up spacecraft for Chang'e 1 already built. Initially it was supposed to be launched as-is, as a clone of Chang'e 1, but now it's confirmed it will carry more powerful instruments.

Novosti-Kosmonavtiki also says the moon rover will be launched no later than 2013. The moon rover will study the local resources, particularly minerals. The rover will be a stepping stone to a human mission to the Moon, which has to occur no later than 2030.

A new article plus a thumbnail of the topographic map. Do you have any idea if we already have a bigger version somewhere?

100 km closer using the same spacecraft bus & upgraded instruments, eh? They don't seem too worried about thermal problems.

Perhaps with the information gained from their first lunar mission, they're confident they'll be able to handle it. On the other hand, if they suddenly consider raising altitude for a better view, we'll know what's happening laugh.gif

LRO's at 50 km and it's not bothering them.

Surely. I was being kind of elliptical; it appears that they are quite confident in their basic design is what I meant.

Yes, we have. See attachments below. First one is topographical map from Chang'e Laser Altimeter with North/South pole views presented. Second one is a kind of microwave map at 37 GHz. I can't translate the title, but I suppose it presents a microwave emissivity of the moon regolith.

(checking in from vacation)

(like, who can stay away from UMSF even if a vacation is supposed to be happening?)

So now I hear that Chang-e 2, the Moon orbiter due to launch in October this year, will be carrying a small lunar impact probe, as Chandrayaan 1 did. Presumably it will be testing tracking, altimetry etc., and maybe imaging down to the surface in support of the lander scheduled for 2013.

Microwave brightness temperature (there is a color scalebar in K on the plot..)
This has an emissivity contribution, but is dominated by the physical temperature
which in this case is dominated by latitude.

There have been a few papers published on these (nice) data - possibly some of the
most solid results from Chang'e so far, or at least results complementary to what
everyone else has flown.

e.g. LPSC abstract http://www.lpi.usra.edu/meetings/lpsc2010/pdf/1331.pdf

Chang'e 2 will be launched at 10:59:57 UTC, tomorrow.
