I didn't see any mention of this elsewhere, but the 21 December drive video showed (a) that video is possible as well as individual images

Are you sure that's not just a timelapse sequence similar to the Yutu deployment cameras where in reality just one frame every 1-2 seconds was taken?

True... I guess I don't know that.

Past days I read somewhere about live HD 3D  video streaming capabilities of Yutu.

this link (in Chinese) gives some details of the future objectives of Yutu's traverses:

a "large stone pyramid" about 42 meters SW of the lander, the a high ground to the W and a crater 10 m to the N.
the link also gives some detail of the driving sessions.

Interesting: if Chang'e 3 will last up to april 2014 (4 months rather than 3), it will be able to witness both a lunar eclipse and a solar eclipse!

April 15th: total lunar eclipse; this will result into a solar eclipse seen from the Moon:

April 29th: annular solar eclipse:

Not sure about what will be visible from the Moon. Will the Moon create a shadow track or just a penumbra track?

Which eclipse simulator do you suggest to see eclipses from the Moon?

Is it true that the lander still has significant amount of fuel? Now that the rover has departed from landing site, I wonder if it is possible for the lander to take off and land somewhere nearby.  ::)

That would be like Surveyor 3's "hop" on the Moon.   (Hmmm, I think it was #3!)

No mention here, but apparently they are now in sleep mode. I'll look for a news link to post.

An article indicating that the lander and rover were due to enter sleep mode at 7 AM Beijing time on Christmas Day.

The forthcoming lunar night, expected to begin on Dec. 26, will last for about two weeks, experts with the center estimated.
That was a chuckle for me. I'm sure their experts are doing slightly better than "estimating" it at "about two weeks" : )

Blame the translation. There will continue to be 'errors' like this unless the translators are regular visitors to this forum or another. *Or even the Chinese journalists in the first place. Not that I enjoy this game of telephone.

Xinhua news agency, 24th December
 Deputy Director, Wu Fenglei of the Beijing Aerospace Control Center said the lander will be scheduled around 7:00 in the morning on the 25th into the lunar night sleep mode and the lunar rover will start its lunar night sleep around 1:00 on the 26th December.

Xinhua news agency, 25th December
...They had to sleep for about half a month, about in January 12th next year to "wake up", continue to work.
