this time they seem even less willing to release pics than they were with CE-1

Have they taken any yet?
We're told that imaging of the landing site will be today. There may simply not be much to release yet. -------------------- -- Hungry4info (Sirius_Alpha)

Right - as I understand it there are only test images so far. This is not a global mapping mission (with the camera, maybe it is with the other instruments), it is intended to focus on specific future landing sites. So Chang-e 2 has dropped into its lower perilune orbit for a short imaging period, maybe only a few orbits. Then I assume they will raise perilune again and wait until the groundtrack crosses another target under good lighting conditions, drop it again and so on. They have lots of fuel, so they can presumably do several of these sessions. Presumably the target areas will also be imaged under optimal lighting conditions from 100 km for wider coverage at intermediate resolution.
No word yet on the suggested impactor. A page on technical innovations referred to a 'landing camera', which might be part of it. Phil -------------------- ... because the Solar System ain't gonna map itself.

Got this via email today from Yong-Chun Zheng at National Astronomical Observatories, Chinese Academy of Sciences
QUOTE Chang'E-2 lunar probe has entered into the 100km x 15km orbit, and begun to take photo for Bay of Rainbows.
Engineers of Beijing Aerospace Command & Control Centre (BACC) have maneuvered Chang'E-2 into the 100km x 15km orbit in the night of 26, Oct, 2010 (Beijing Local Time). BACC is the commanding, decision-making and control centre of the key space flight missions in China. This action of Chang'E-2 was begun at the farside of the Moon, and reqiure high accuracy of orbit control. In the 100km x 15km orbit, Chang'E-2 is taking images for the Sinus Iridum, or Bay of Rainbows, where will be selected as the site for the soft landing of Chang'E-3. In the future several days, Chang'E-2 will obtain high resolution images of this regions. After taken photoes for Sinus Iridum, Chang'E-2 will go back to the 100km x 100km orbit, where it will stay for half a year to explore the lunar surface. -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

Latest news - Chang-e 2 has been raised to its long term orbit and will now do more imaging and other mapping from that altitude. No more news on the low altitude results yet. I had assumed they would repeat the low altitude imaging elsewhere but apparently not, as Emily's reported email had also said. We'll learn more later... too bad it's so slow coming out.

Thanks for the update, Intrepid Correspondent, and best of luck on your launch!
Interesting. So have they completely ruled out any future low-alt passes now? -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

The paper Chang'E-1 lunar mission: an overview and primary science results is available for free on the website Chinese Journal of Space Science. I am not sure that there is anything new in there

Finally! A report with image and coordinates. No word on that rumor of an impact probe. Phil -------------------- ... because the Solar System ain't gonna map itself.

more images at a decent resolution

Be sure to watch the first one until the end! I almost stopped once the panels deployed, but skipped ahead and then had to rewatch the whole thing again.
I really like the trend of "engineering" cameras such as these, Mars Express' VMC and Ikaros DCAMs! -------------------- Space Enthusiast Richard Hendricks

For some reason - none of those links work - (the entire domain doesn't exist at my end)
http://www.youtube.com/watch?v=nWHU4VMGDDM However - that YouTube link contains all of them, I think |
