When can we expect release of LROC images?

While we wait for more images and science data in January 2014 here is a JOKE :-

Why did The Princess and her Rabbit ( Change'3/Yutu ) have to land in Mare Imbrium ?

Because the "Man in the Moon" said "You cannot park in that Bay !! "   
 
(Think car parking attendants ! )

Any update on the LROC images?  They should have been obtained five days ago.

last update was posted on 14th of dec, although @LRO_NASA has been chattering on twitter two days ago. Nothing about CE-3 so far. I noticed there is a  cool LRO tracking page

Don't get too excited about the LROC images.  Yes, they will be nice to have, but LRO is now in a higher orbit than when it started, with 2 m/pixel images instead of 50 cm resolution.  The lander will only be about 2 pixels across, the rover maybe only 1 pixel across.  We have previous LRO coverage at 1.5 m/pixel to compare it with, showing the very large rock SW of the lander - now there will be a second 'rock' which will be the lander, and a third small one which will be the rover.  Tracks will be very hard to see because of the lower resolution, and  because the new image has a fairly low sun angle (taken about the time the lander shut down for the night).  Later images with higher sun may do better at showing tracks, and when we get them in a few months there will be more tracks to see (if they show at all).

Call *that* a, you know, wossisname?

Losing the will to live...

Nope, lost it! At least there have been a total lack of 'no atmosphere' efforts (notice the entirely appropriate absence of the 'j' word from this post!).

That's a shame.....

Nice - actually a bit better than I expected - so that's good! - but the tracks are not resolved as far as I can see.

Excellent!

It may be my imagination but I think there a faint wiggly track connecting the lander and the rover

I know what you mean, but on the before/after GIF on the LRO site, that dark wiggly line is there before the landing as well.

this week's issue of Aviation Week has an article on the development of CE-3's throttling main engine.
anybody willing to post it here?

No, because it's obviously copyrighted.

This isn't up for discussion, this is a warning to all.

Any idea why the rover's shadow is larger than the lander's?  Shouldn't it be the other way round?
