As many of you know, I have a neighbor who works at the School of Earth and
Space Exploration at Arizona State University.
He was the source of the donated books, enjoyed by members of both SAC and
EVAC.
Anyway, his link is a good read. Thought you all might enjoy.

I had not?. And yes, I enjoyed it.
I also looked at the other images. VERY IMPRESSIVE.
I will forward this on to the EVAC list. They will enjoy it also.

ARIZONA STATE UNIVERSITY News Release
June 29, 2011

Arizona State University researchers have released a stunning image of the
Moon?s prominent impact crater Tycho, taken with the Lunar Reconnaissance
Orbiter Camera (LROC) on 10 June 2011. This dramatic sunrise view of Tycho
crater captured by Professor Mark Robinson?s LROC team with the narrow angle
camera could be considered one of the most beautiful images of the Moon
taken to date.
?We planned the image because it would dramatically show the geologic
relations from a more human perspective. Drama we got!? says Robinson, a
professor in the School of Earth and Space Exploration at ASU. ?When I first
saw the reconstructed image all I could think was what it would be like to
be on the first mission to Tycho. Imagine coming in for a landing within
this geologic wonderland! When can we go??
Named after the Danish astronomer Tycho Brahe, the relatively young Tycho is
the most conspicuous crater visible when the Moon is full. It is a very
popular target with amateur astronomers because it is surrounded by a
distinctive dark halo and radiating bright rays. Located in the southern
lunar highlands at 43.37°S, 348.68°E, the approximately 82-kilometer (51
miles) wide Tycho crater fits the mold of a typical large complex impact
crater with its flat floor, terraced inner-rim walls and prominent central
peak. The summit of the central peak is 2 km (6562 ft) above the crater
floor, and the crater floor is about 4700 m (15,420 ft) below the rim. Many
"clasts" ranging in size from 10 meters to 100s of meters are exposed in the
central peak slopes.
Tycho's features are so steep and sharp because the crater is young by lunar
standards, only about 110 million years. Over time micrometeorites, and not
so micro meteorites, will grind and erode these steep slopes into smooth
mountains.
Another NAC image pair (below) acquired on 27 May 2010 gives an excellent
straight down view of the summit, including the large boulder seen in the
oblique view. Fractured impact melt deposits surround the boulder. These
LROC images clearly show that the central peak formed very quickly; the peak
was there when impact melt that was thrown straight up during the impact
came back down. The fractures probably formed over time as the steep walls
of the central peak slowly eroded and slipped downhill. Eventually the peak
will erode back such that the big boulder will meet its demise as it slides
2000 m (6,561 ft) to the crater floor.

on Tycho, and a video.
