The landing area shown in that abstract is plotted here as a red box on a Quickmap background:

So not necessarily literally in Sinus Iridum, it may be outside but nearby. I don't know of other areas with the very high resolution coverage, so Chang'E 4 may be targeted for the same region, and maybe even the later sample return missions. Still quite a lot of scope for different sites and surface compositions here.

Back to lunar missions smile.gif where the Chang'e 3 lunar lander is expected to fly
to the Moon "in the second half of 2013".

Chang'e 3's RTG could permit it a 30 year lifespan.

Of course, a mechanical or electronic failure is likely to end the mission long before the RTG wears out (same as on Curiosity)

I've put together a Flickr album of all the images of Chang'E 3 that I've been able to find online. There is one particularly visually striking little animation that was shown as part of a news broadcast, showing the rover making tracks on the Moon, driving toward the Sun. I'm using it to illustrate my story on Chang'E 3 even though the quality of the screen grab is very poor. I would love to try to create a higher-resolution version of this illustration by combining some lunar landscape photo with some hand-drawn silhouette of the rover, but I don't have time to try and don't even know if my artistic ability is up to the task. So I throw the idea out there in case anyone else wants to take up that challenge!

Bonus: a Flickr album of very bad quality screen grabs from Ouyang Ziyuan's talk showing Chang'E 5 artwork.

I don't understand why space geeks are not excited about Chang'e 3. I mean, I have seen a space.com post on the 13 missions worth following in 2013 and it's not even included...
just a reminder for the history-oriented: CE-3 will attempt the first lunar soft landing in 37 years (since Luna 24 in 1976) and will deploy the first lunar rover in 40 years! (the last was Lunokhod 2 in 1973!)

I would say that partly to blame is the (relative) lack of publicly available information. I suspect
that, once it launches and touches down everyone will go bonkers about it.

By the way, the image that accompanies Emily's most recent post reminds
me of an animation of MER rover operation that was created for PR purposes
before landing back in the early 00s. I recall seeing the MER roving
towards the sun during the concluding part of that animation.

I also wonder if any part of the landing sequence for CE3 could be visible from Earth.

I suppose that the landing might be barely visible to LRO if the latter is in a favorable orbital position at the time, but suspect it would be quite underwhelming since of course Chang'e-3 won't be using a parachute.

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.

I can't find any information on how the RTG is powered? Does China have it's own PU-238?

Ouyang Ziyuan is reporting that the launch of Chang'e 3 may come as soon as June 2013! That's much earlier than what I have expected...... blink.gif
