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...
We model the primary crater production of small (D < 100 m) primary craters on Mars and the Moon using the observed annual flux of terrestrial fireballs. From the size–frequency distribution (SFD) of meteor diameters, with appropriate velocity distributions for Mars and the Moon, we are abl...
One of the published images is a 360-degree panorama which was pieced together from 80 photos taken by a camera on the lander after the rover drove onto the lunar surface, according to Li Chunlai, deputy director of the National Astronomical Observatories of China and commander-in-chief of th...
The detected craters are fitted with ellipses and matched to a Lunar Crater Database previously created. The matching of the two sets permits the computation of the absolute position of the camera. A Kalman Filter uses this information... M Mammarella,MA Rodrigálvarez,A Pizzichini,... - Spri...
Are small (less than ∼1 km diameter) craters on Mars and the Moon dominated by primary impacts, by secondary impacts of much larger primary craters, or are both primaries and secondaries significant? This question is critical to age constraints for young terrains and for older terrains coverin...

Four hundred years ago an Italian scientist named Galileo Galilei became the first person to see the craters(环形山) on the moon. Galileo was one of the first people to use a telescope to study the sky. Since then telescopes have bec
NASA captured a satellite image of Mars that appears to show an adorable bear's face on the red planet.NASA/JPL-Caltech/UArizona The image was shared on Jan. 25 by the University of Arizona, which operates theHiRISE cameraon the Mars Reconnaissance Orbiter (MRO) that has been capturing ...
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...
