Scientists have discovered a rare meteorite a wheat field, For the detection of cosmic rarity “was used new, so-called penetrating radar technology that could be used anywhere: on Mars.
However, in order to retrieve a meteorite from the Earth, scientists had to use very simple tools-brushes. And all this in order to maximally preserve traces of a meteorite impact.
Brenham meteorite, scientists say, collided with the ground over 10 thousand years ago in the Pleistocene Epoch.
According to the Director of the Department of Astronomy of the Houston Museum of natural history by Carolyn Sumners, “possibly, the original inhabitants of America saw it falling.”
Less than 1% of the meteorites discovered on Earth apply to the type of pallasite meteorites. This is a fairly rare type iron-stone meteorites, which consist of approximately the same amount of nikelistogo iron and olivine. Pallasite meteorites have a kind of internal structure, which indicates that they were formed in the absence of any significant gravity. Scientists believe that these meteorites are fragments of destroyed small planets or major asteroids.
Sophisticated metal detectors at the site of the search showed the existence of an object, as scientists had hoped for, search pallasita. Joy scientists a few dented when GPR (Ground Penetrating Radar) instead of meteorite discovered steel cable.
However, scientists continued to search for, and at a depth of more than one metre below ground was discovered exactly meteorite, weighing about 70 kilograms.
GPR technology was used previously for detecting meteorites in Antarctica, where ice allows the sound penetrate at considerable depth, and get an accurate three-dimensional image of the object located even deep underground. Scientists intend to use similar radars for detecting meteorites or water on Mars.
