Hm, there is some confusion with the orientation.
The rover left the lander towards the north, not south.

And the Earth should be in the opposite direction,
and higher above the horizon...

And the sun... ohmy.gif

But besides these points, it's nice to move within the panorama.

this image from one of the TV reports has been posted on a French forum

I think we have never seen it before, and it looks like a perspective from late on the first lunar day

EDIT: I post the image below because I don't trust these image hosting sites...

That hazcam image appears to show the arm deployed. I wonder if this was taken around the time that the first APXS spectrum of the lunar soil was obtained.

Thanks Paolo for the image!
The news about Yutu signal detection, after initial unsuccessful attempt on Monday, is intriguing... could it be related to the late wake-up of the lander who received the rover signal and re-directed it to Earth?

I believe the Chinese deserve many kudos for achieving what they have managed to achieve on this flight. Historically, a given country's first attempt at a specific type of mission is not completely successful. Just in terms of lunar probes, the first Soviet and American missions failed (either partially or completely) on the order of four times out of five.

Granted, the Chinese are somewhat standing on the shoulders of giants, the state-of-the-art being so much more advanced now in so many of the fields (electronics, communication, propulsion, etc.) that must come together for a mission like this to succeed. But that has historically been true for every other "first" attempt at a given mission. The very first people to try something are always stepping into the unknown.

However, I am positive the Chinese will learn from Chang'e 3's failures as well as its successes, and we are likely to see a more robust unmanned lunar exploration program as a result.

Even if we don't get any more beautiful images from Yutu, I'm impressed with the capability displayed. And I'm already looking forward to seeing what Chang'e 4 will accomplish.

Chang'e 4 may not actually fly.

Right... and that link (which looks more like someone's opinion rather than official policy) did say 'if CE3 is successful...' So I would say a CE4 mission that tries to solve the Yutu problems is very likely.

Probably depends on if they can solve the problem on Yutu.

I have found this image from Yutu linked in a Russian forum. I think it's from the first lunar day

edit: I have attached the image to the post, in case it disappears...

That can only be the large 'pyramid' rock which was approached during the second day. On my map I showed the rover near it on January 14th and 15th - keep in mind the dates are assumptions and might not be exactly correct. The picture had to be taken on one of those two days.
