NASA’s Lunar Reconnaissance Orbiter has been circling the Moon since June 2009 and has been imaging the lunar surface at much higher resolution than obtained during previous missions going back to the Apollo era. The images can be quite spectacular and some of the most striking are currently on display in an exhibition called A New Moon Rises at the National Air and Space Museum in Washington D.C. Here is a report on the show: Desolate magnificence – The Space Review.
The image below shows “A Very Young Crater” with [spectacular] ejecta surround it. The crater is
about 1,400 meters (4,600 feet) across. Since there are no superimposed impact craters on the ejecta, and the delicate lacy impact spray is still preserved near the rim, this crater formed very recently, perhaps sometime in the past few thousand years.
Below are two “Copernican Craters” that have
… large, spectacular ejecta patterns of bright material thrown across the Moon’s surface. These craters are no more than 1 billion years old—”Copernican age” in the lunar geologic timescale. Because they are so bright and have few impact craters on them, they may be as young as a few million years. Each is incredibly well preserved: crisp crater rims, steep crater walls, and delicate small-scale ejecta patterns. The overhead sunlight highlights the brightness variations.
The lunar feature below is titled, “The Strangest of Swirls”
Reiner Gamma is one of the Moon’s most distinctive and mysterious features. This striking, tadpole-shaped swirl puzzles lunar scientists. Some think that its origin, as with other swirls, is somehow related to the shielding effects of localized magnetic field anomalies.
The images below
…, taken at different times, reveal that a cave extends at least 25 meters (82 feet) under the surface of the Moon. Collapse pits, where the near-surface lunar crust has caved in, can provide a window into the shallow subsurface. Image IDs: M126710873R, M155016845R, M152662021R
