The origin of lunar crater rays
Lunar rays are filamentous, high-albedo deposits occurring radial or subradial to impact craters. The nature and origin of lunar rays have long been the subjects of major controversies. We have determined the origin of selected lunar ray segments utilizing Earth-based spectral and radar data as well as FeO, TiO2, and optical maturity maps produced from Clementine UVVIS images. These include ray...

متن کاملMeteor Storm Evidence against the Recent Formation of Lunar Crater
It has been suggested that the formation of 22 km diameter lunar crater Giordano Bruno was witnessed in June 1178 AD [1]. To date, this hypothesis has not been well tested. Such an impact on the Earth would be “civilization threatening.” Previous studies have shown that the formation of Giordano Bruno would lead to the arrival of 10 million tonnes of ejecta in the Earth’s atmosphere in the foll...
متن کاملThe Nature of Crater Rays ' The Copernicus Example
Crater rays are formed during a cratering event as target material is ballistically ejected to distances of many crater radii forming narrow, generally high albedo, approximately linear features extending outward from the crater. The nature of crater rays was examined for the lunar crater Copernicus using new information on, the composition of surface material (from near-IR reflectance measurem...
متن کاملLack of exposed ice inside lunar south pole Shackleton Crater.
The inside of Shackleton Crater at the lunar south pole is permanently shadowed; it has been inferred to hold water-ice deposits. The Terrain Camera (TC), a 10-meter-resolution stereo camera onboard the Selenological and Engineering Explorer (SELENE) spacecraft, succeeded in imaging the inside of the crater, which was faintly lit by sunlight scattered from the upper inner wall near the rim. The...
