In Kansas the rare meteorite is discovered

For scientists it was possible to reveal rare meteorite in the wheaten field in the state of Kansas.

For detecting the "space rarity" was used the new, so-called penetrating radar technology, which could be used somewhere... on Mars.

However in order to extract meteorite from the earth, by scientist it was necessary to use very commonplace tools - small brushes and sovochkami. And all this in order to maximally preserve the tracks of the action of the impact of meteorite.

Meteorite Brenham, in the opinion of scientists, encountered with the Earth more than 10 thousand years ago in the epoch of Pleistocene.

According to the director of the division of astronomy of the Houston museum of the natural science Of kerolin Of samners, "possibly, the natives of America saw its drop".

Less than 1% meteorites of those detected on the Earth relate to the type of pallasites. This is the sufficiently rare type of the iron- rock meteorites, which consist of an approximately identical quantity of nikelistogo iron and olivine. Pallasites have the unique internal structure, which indicates that they were formed in the absence of any significant gravitational force. Scientists consider that such meteorites are the fragments of the destroyed small planets or large asteroids.

The most complex detectors of metal in the section of search showed the presence of a certain object, as hoped scientists, desired pallasite. Happiness of scientists is somewhat tarnished, when geo-radar (Ground Penetrating Radar) instead of the meteorite revealed steel cable.

Nevertheless, scientists continued searches, and at the depth more than meter underground was discovered precisely meteorite, by weight about 70 kilograms.

Technology GPR was used earlier for detecting the meteorites in Antarctica, where it makes possible for sound signal to penetrate ice to significant depths, and to obtain the precise exploded view of the object of that being being located even is deep underground. Scientists are intended to use similar geo-radars for detecting of meteorites or water on Mars.
