An article with interview to Zhang Yuhua, deputy chief designer of the lunar probe system for the Chang'e-3 mission:
http://news.xinhuanet.com/english/china/20...c_133499472.htm
Based on this interview, Yutu might have been damaged by knocking against rocks on a lunar surface that is more complicated than expected from "foreign researchers" data (no comment!).

The latest from from https://twitter.com/uhf_satcom is that Yutu has been transmitting again in the last few days. Still alive! This was the 9th lunar day for Yutu - just ended.

Albeit its functionality is severely limited, it is now the second longest lived lunar rover, having exceed the 3 short-duration Apollo rovers and
Lunokhod 2, which only made it through 4 lunar days. It is creeping up on Lunokhod 1, which lasted over 11 lunar days.

yes, but one could argue that, since it has been unable to move for some time, it can no longer be considered a "rover".

Was Spirit not a rover anymore when it got stuck? I think it was! wink.gif
Unless Yutu's wheels suddenly fall off it should be considered the same...

Senior management would disagree

QUOTE (NASA Release)
After six years of unprecedented exploration of the Red Planet, NASA's Mars Exploration Rover Spirit no longer will be a fully mobile robot. NASA has designated the once-roving scientific explorer a stationary science platform after efforts during the past several months to free it from a sand trap have been unsuccessful.

Touché, but even the team members' quotes refer to Spirit as a rover when talking about its future life expectancy!
Let's leave well enough alone; we could open a can of worms like the planet definition debate....

When did a scientist or engineer ever take instruction from management on such a topic?

So on a different topic......there is an exhibition about Chang'e 3 (as well as the orbiters #1/2) right now at the Hong Kong Science Museum, which has some big models of the lander and rover, as well as some back up hardware of the science instruments on display. I took some photos yesterday and I shall put them up here shortly. wink.gif

an update in Chinese on Yutu and Chang'e 3: Yutu is about to enter its 10th lunar day and four instruments are operating normally (camera, radar, APXS, IR spectrometer).

Link to a video of a panorama from Yutu. If anyone finds the pan as a downloadable image, please let us know!

EDIT - I just did a quick reprojection job and realized - this is not from the end of the route as I assumed at first, or as a description of it seems to suggest - this is from very close to the big rock (Dragon Rock) at the position labelled 14-01-2014 on my route map. So it is newly released but not newly taken.

thanks for clarifying this. I had the same impression but I have seen the new panorama reported many times as newly taken
