Two very “fresh” in geological terms crater on the moon discovered by a group of specialists under the leadership of Thomas Greathouse of southwest research Institute in boulder. To detect traces of the falling asteroids near the South pole of the satellite was managed with the help of the LRO probe.
The craters are discovered on the so-called “dark side of the moon”, never directly illuminated by sunlight. To study this phase of the satellite, the experts use the cameras in the ultraviolet range, because in it the Moon is lit much brighter by the light of the stars. To detect new craters and to determine their age specialists manage due to subtle fluctuations in albedo, the diffuse reflectivity of the surface of the moon. Also in studies of this kind is used information about the reflection from the surface of radio waves.
Measurements have shown, the age of the one of the detected craters is about 16 million years. The second crater is over 75 million years old, but still considerably “newer” many others located on the satellite. The diameter of the two craters is about two kilometers.
As stated by researchers, studying the craters that dotted the Moon, using them allows the prism to learn a lot about the history of the moon and the entire Solar system. Their work, the scientists published in the scientific journal Icarus.
Probe LRO, or Lunar Reconnaissance Orbiter is an artificial satellite of the moon. It was launched on 19 June 2009 and 23 June entered the lunar orbit. Thanks to data obtained with this probe in the past, scientists have managed to collect a lot of information about the moon — including to find the atoms of helium in its atmosphere and the argon atoms in the soil, and also to detect deposits of ice in one of the lunar craters and in General to clarify the estimated quantity of water in the lunar soil.Related posts:
