Due to the tremendous energy released by an impact event large portions of the target rock is melted. This impact melt forms distinctive flows and ponds both inside and outside of its parent crater. In many young craters the #LROC-NAC has captured deposits that look as if they formed yesterday.

Today's Featured Image is on the northern slope of the Hayn crater central peak. Due to the peak's steepness, it is rough and craggy. In many places on the peak wavy deposits are seen between crags and blocks; these deposits are most likely impact melt. Truly amazing, first the central peak formed then impact melt splashed down and coated it. If this interpretation is correct you can say that the peak formed in matter of a few seconds, quickly enough that melt that was thrown during the impact had not yet landed! Quantitative measurements of these kind of spectacular outcrops, using new accurate topography from LROC NAC stereo will help reveal how impact craters form.

Hayn is an exceptionally deep crater because it is situated just within the northern mountainous ring of 550 km-wide Humboldtianum basin, which extends far beyond its deep interior Mare Humboldtianum. The entire basin straddles the 90° east meridian, though Mare Humboldtianum is a nearside basin visible at favorable lunar librations. The floor of Hayn is 4.9 kilometers below global mean elevation and it's northern crater rim is still more than a half kilometer below global mean. The mountain directly north of Hayn, a worn remnant of the Humboldtianum basin rim is 2.3 kilometers above global mean, nearly a seven thousand meter change in elevation over the eighty kilometers between that massif and the center of Hayn.

Lichtenberg B Flow |LRCO

Starting at the rim of the crater Lichtenberg B, impact melt flowed and formed a channel, pushing boulders aside in the process. LROC NAC M120257109R, image width is 430 m, incidence angle is 57°

LROC Moon |Nature's Art

Western half of an unusual unnamed crater and its ejecta near the center of Mare Serenitatis.

In many cases crater ejecta patterns on the Moon 
result in natural art.



Unlike the ejecta on the Earth and Mars, ejecta on th
Moon does not interact with an atmosphere.


Thus the final pattern on the ground is solely a reflection the 
dynamics of impact cratering. Today's Featured Image highlights 
the western half of an unnamed crater located in the middle of
Mare Serenitatis. The crater diameter is about
470 meters.

Context view of today's Featured Image, showing a wider view of the unnamed crater ejecta. Field of view close to the full  2.2 kilometer width of LROC NAC frame M139795376L. See the larger context image accompanying the image  release HERE [NASA/GSFC/Arizona State University].

As seen in the second picture (a zoom-out of the same NAC frame), one third of the ejecta blanket (the western portion) is missing, probably due to an oblique impact from west to east. In the top image (near the crater center), almost all of the boulders are ejected in the northwest and southwest direction. The fine particles, however, extend out to the west in patterns not unlike a delicate lace. Studying the full variety of craters with distinctive ejecta patterns is key to understanding the dynamics of oblique impact events.

Another very familiar crater famous for its asymmetric ejecta and as a nearside landmark of the Moon in an evening sky is bright Proclus - with lighthouse rays guarding "the gates" separating distinctive Palus Somni from Mare Crisium.

Ray of boulders |LROC

Dozens of boulders, ranging from 10 m to more than 30 m in diameter, are distributed within an ejecta ray close to the crater rim (lower right). These boulders represent the deepest material excavated during crater formation.

First Chang’e-2 Photos |China

China has released the first photos from it’s recently-launched
Chang’e-2 lunar orbiter!

Released with some fanfare (that’s the Chinese premier, Wen Jiabao,
there. [Editor's note: originally had Jiabao as the 'head of state'; that
would actually be the president, Hu Jintao, not the premier, Jiabao]),
the images get more or less straight to the point: they’re of the Bay of
Rainbows (Sinus Iridium), which China has slated to be the potential
landing location of it’s Chang’e-3 rover mission.

The images include a 3-D map, and have a resolution of ~1.3 meters
(for comparison, NASA’s Lunar Reconnaissance Orbiter has resolution
up to 1 m [PDF]).

Check out the official Chinese release page for all the images:
A rough translation notes the last image is labeled as “antarctic”,
so it’s unclear if that’s also a Bay of Rainbows crater, or one near
the lunar south pole.
