Thank you! Good work. My phone only works on this site not UMSF, so that helps!

Didnt make the front page of reddit at all, but obviously peaked http://www.reddit.com/r/space/
Scratch that, this post went to front page. Lots of complaints about mainstream media failing to cover this

I followed all of the Apollo landings "live", twice on radio and the others on TV, and I got the same "buzz" with all of them - and the same for Chang'e 3.

Me too, and you're absolutely right - the buzz is still the same... I was glued to every minute of it.

I remember looking up at the Moon on Christmas 1968 and a shiver going down my spine realising there were three men orbiting it. Same for the landing missions. It's never looked the same in all the years since.  :( Last night, I looked up (it was clear!!!) and felt the same way - wishing Jade Rabbit good luck for today...

It's a sobering thought that there are children alive today whose grandparents weren't born when Apollo 11 landed! But today gives hope that I may yet be able to hang on long enough to see more humans tred the dust of another world...

P.S. Check out the Apollo 11 Flight Journal Day 5 at MET 095:17:28 http://history.nasa.gov/ap11fj/14day5-landing-prep.htm . Funny old life, isn't it...?  ;)

By a very strange coincidence, at the time Change'3 was making its descent to the lunar surface , the book "An Introduction to the Mathematics and Methods of Astrodynamics , Revised Edition" by Richard H. Battin - which I had ordered some weeks ago from an Amazon dealer  - arrived by UK Royal Mail . Literally, 4 minutes before touchdown of Change'3 :-))

How strange is that !

For those not familiar with the name Richard H. Battin he was the Technical Director, Mission Development for the Apollo Guidance and Navigation Program during the 1960s. In fact, I have several of Dr Battin's  papers including one  called "Explicit and Unified Methods of Spacecraft Guidance"  which carries a very good "easy mathematical" treatment of the Apollo trajectory from Earth to the Moon.

The book "An Introduction to the Mathematics and Methods of Astrodynamics , Revised Edition" is a different mathematical "animal " though :-))

So has landing site been confirmed as not being in sinus iridium yet? I notice the tv presenters were all referring to bay of rainbows in their pieces. only 2 hours togo for jade bunny to hop off lander  8)

Correct. We landed in north central Mare Imbrium. Lat: ~44.1260, Lon: ~-19.5014.

A "Spaceflight Now " report also suggests that the initial landing coordinates are:-

"....An initial position estimate put the landing site at 44.12 degrees north latitude and 19.51 degrees west longitude. The estimate will be refined over the coming days....."

Here is a "rough image" where that is - close to Laplace F crater on the map in Mare Imbrium.

Has there been any announcement of CCTV live coverage of the Yuto rover?

Here is a better map having a "stab" at where Change'3 is on the lunar surface based on coordinates published so far.

Based on IAU/NASA/USGS online lunar maps

Are you aware of the analysis of the descent images here? http://forum.nasaspaceflight.com/index.php?topic=33511.msg1133006#msg1133006

I'm fairly certain the landing site is pinned down to within a few metres.

That's one small step for mankind, but a giant leap for China!

Congratulations to the Chang'e 3 team.

Yes aware of coordinates but it was an "early stab" at trying to show where on a lunar map - not a "guess" at co-ordinates.

Here is an even better map

Look it up on the LRO website Hungry4info3 was posting pictures from:  http://target.lroc.asu.edu/q3/ .  You can zoom in from the big picture all the way down to 0.5m per pixel, and lattitude and longitude at your mouse cursor are marked at the finer resolutions.

According to CCTV, Yutu has successfully separated from the lander.
