QUOTE (dilo @ Dec 28 2013, 06:50 PM)  Thanks, Paolo! I found other interesting videos from same peson (H.Kenhmann) and in particular this one, posted one week ago and showing a video sequence of rover in movement (almost real-time movment, I guess): http://www.youtube.com/watch?v=kwxwX4xqLRw (very nice speaker at beginning!) Nice find! Went diggin on youtube after, found this interesting video, a scientist explaining some of the photos. She mentioned the crater seen in one of the rover photos is aprox 10m+ from the lander. http://www.youtube.com/watch?v=0y6o9bX67uU |

QUOTE (Lightning @ Dec 30 2013, 11:18 PM) Finally: Chang'E 3 as seen by LRO: Nice, the lander stand out, but at least I would not figure which ones of those smaller dots were the rover unless it had been indicated.

APXS used just before shutdown! So now we know that every instrument on the rover (and as far as I know on the lander as well) has been tested during the first lunar day. Phil -------------------- ... because the Solar System ain't gonna map itself.

Here's a quick overview of the mutual photography images released so far. For some we only have screencaps. In some cases I've assembled the larger original frames from the various zooms shown in videos.
It's not an artistic composition, but I think it helps in keeping track of things. Images are grouped by the a, b, c and d stops shown on maps.

My friends at Tsinghua University sent me the coolest Christmas toy ever - scale models of the Long March 3 launch vehicle, Chang'E lander, and Jade Rabbit rover. These are very cool - antenna booms and solar panel hinges articulate, rover wheels turn!

WANT
 That is so cool. I would love to see a few more photos of that from different angles.

We have a result from the APXS carried by Yutu:
 QUOTE An initial analysis indicates that eight major rock-forming elements (Mg, Al, Si, K, Ca, Ti, Cr and Fe) and at least 3 minor elements (Sr, Y and Zr) of the Moon can be identified in this spectrum. APXS obtained its first spectrum of lunar regolith |

So it seems, they take iron-55 and cadmium-109 as nuclides for APXS, with Ag K-alpha (from Ag-109 as electron capture "decay" product of Cd-109) at 22keV responsible for the Rayleigh and Compton scattered x-rays, and excited Mn from decaying Fe-55 responsible for the additional Mn K-alpha and Mn K-beta lines.
"esc" probably means "escape peaks", detector artifacts. |
