Nice and convenient method for viewing large images.

For some reason these remind me of Cassini's hi-res images of Phoebe.
How strange it is to look at somewhere just next door and think of something far more distant and alien. Surely a sign of just how long it's been since we last had lunar imagery of this kind. |

WOW...incredible.
If these early images are anything to go, we're in for a treat over the next year or so John |

Yes, a real treat!

I'm impressed that the first calibration image, from the "commissioning" orbit (higher than the final science orbit, IIRC) is stated to have a resolution of 73cm per pixel.

The current orbit is 30kmx199km. Periapsis is at the south pole. The science orbit is nominally 50km circular. So this image, assuming that the resolution is listed correctly, was taken at a lower altitude than the science orbit. The nominal resolution is 50 cm from 50 km (1 m summed).

On July 3, LRO officially entered the Instrument Commissioning Phase. See http://lroupdate.blogspot.com/ for further details.
A first LROC picture taken on July 3 has been issued as well (a region south-east of Clavius); see page http://lroc.sese.asu.edu/news/?archives/66...-Highlands.html |

Fascinating -- this surface strongly resembles the "elephant-skin" surface observed in some of the Ranger IX photos of Alphonsus and around Gassendi. Among many other places.
My understanding of the best speculation on what forms this kind of surface is that we're looking at debris flow patterns from large-scale ejecta events (i.e., basin ejecta emplacement events). If this is in the Clavius region, would that imply we're looking at Aiken Basin ejecta debris flow? -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

I like the 'debris flow' hypothesis -- very interesting.
There definitely are series of striations running diagonally across the picture from upper-left to lower-right. However, depending on the exact location of this lovely shot, I wonder would these be due to Tycho's influence -- just north of Clavius, or, are they, an integrated effect of the above flow hypothesis?

Many thanks for that heads-up. That's a nice image, very abstract and sparse... like it a lot. I get the feeling that we're going to get quite a few unintentionally "arty" shots from LRO.
