The surface of the Moon is highly cratered due to impacts of meteorites, asteroids, comets and other celestial objects. The origin, size, structure, age and composition vary among craters. We study a total of 339 craters observed by the Lunar Reconnaissance Orbiter Camera(LROC). Out of these...
The Moon is a cold, dry desert. Unlike the Earth, it is not surrounded by a protective atmosphere and water which existed during the Moon’s formation has long since evaporated under the influence of solar radiation and escaped into space. Nevertheless, craters and depressions...
Combining camera data from Lunar Orbiter, Lunar Reconnaissance Orbiter (LRO), Kaguya and Chang'e-1 missions, 5 representative large Copernican craters on various terrains of the lunar surface are chosen to study the origin of the pit chains in the crater floor. The morphology and distribution ...

"The information from the depths of the moon will be one of our focuses in the exploration," said Li. The CNSA also released a video of the landing process of the Chang'e-4, which was produced by processing more than 4,700 pictures taken by a camera on the probe. ...

The Mars Reconnaissance Orbiter and its HiRISE camera have been examining Mars' surface for years, cataloguing the planet's menagerie of impact craters. One of them, recently chosen as the HiRISEPicture of the Day(HIPOD,) looks like a Thunderbird. Or a dinosaur footprint left in the mud....
to craters of elliptical shape. This was obviously not the case, and so most of the Moon craters could not be meteoritic. At that time, however, the physics of impact cratering implying shock physics was not yet understood. This especially concerned also the vaporization of the impactor by sh...
Using both NAC and Kaguya Terrain Camera DTMs, we also determined the d/D ratios for the set of fresh simple craters larger than 400 m in diameter. The d/D ratios of these larger craters are typically near 0.21, as expected of gravity-dominated crater excavation. Fresh craters less than ...
It turns out that water is slowly escaping the topmost, super thin layer (thinner than the width of a red blood cell) of the Moon’s surface.
