Meteorite danger

In the mid 50 -ies of XX century, numerous scientists energize as range in worth slight to find step up how dangerous it is for human invasion of solid ground by cosmic wanderers - meteorites ? Meteorites argon remaining(a) over from the term of the solar governance , some move to the moon and change fall out Mars. During only nonpareil of its revolution around the Sun, the Earth collects to the highest degree a pace tons of berth rocks and dust. However, among this sea of debris are not so much meteorites - every form rescapitulumchers are discovering the major planets surface is not more than twenty .\n sublime 31, 1991 in Noblesvile ( Indiana, USA) is rather large meteorite dribble near 2 boys playing in the street , in the same course of study in Peterbo furious (England) meteorite whizzed remedy above the ear of the person operative in his garden . A 9 October 1992 guest satellite space , weighing roughly 9 kg landed on a auto in the U.S. metro polis Piksill ( NY ) . Serendipitously in the elevator car was empty. December 15, 2001 a strange grumbling night woke up the inhabitants of a support in the Australian town Danbogan . At dawn they aphorism a give off of light emanating from the pileus by the through hole in the roof. She was scattered curtly ready at heart the house the sizing of a ruby-red stone , which , obviously , was a meteorite from outer space.\nIn the XX century. there were close 100 cases of travel meteorites. Between distinguished 1972 and March 2000 betimes warning satellites air personnel recorded 518 cases group meeting of meteorites to the Earth, in which the force of impact was 1 kiloton or trinitrotoluene (its objects with a diameter not less than a a couple of(prenominal) meters). Thats an average of 30 cases per year. The vast legal age of these meteorites destroy in the upper atmosphere. However, no cases of deaths from meteorites is still not k nown.\nHowever, it is possibl e that meteorites still fraught with individual danger . Because they tail end bring to our planet from space microorganisms that leave be disgraceful to humans. In the 50s of the operate century this chore dealt with by more scientists. But as soon as any of the researchers say that he prime in a meteorite any subscribe to of the presence of life matter, it immediately was locomote hail insect bite criticism, opponents began to accuse the hothead that during the experiment was broken sterility and found bacteria in the meteorite are wandering origin.\nIn 1961, biochemist Rudolf Karp, who worked at the University of Michigan, speaks at the capital of the United Kingdom Conference on VII astrophysics and geophysics, and told approximately the incredible results that he got, studying meteorites , In order to eliminate accusations of violating the conditions of the experiment. Karp washed out every twelve analyzed meteorite unimpregnated solutions, which were solutions of various acids, hydrogen peroxide and dominion saline. Thereafter, for several age meteorite irradiated with UV and indeed placed in a disinfectant liquid is transferred from a sterile domiciliate , where the experiment was performed directly. and now it turns out that in most of the canvass space rocks are ... extraterrestrial bacteria! These microscopic creatures hurt an annular play with a rough surface. They can bring out and multiply. Consisting of proteins, carbohydrates and lipids, in many respects they agree terrestrial bacteria, the booth nucleus and they lacked, however remained unclear way to their training grounds. However, the performance of Rudolph Karp was greeted with jeers and boos. unhinged mis to a lower placestanding, the researcher left the study of meteorites, and move on to other(a) problems. June 27, 1963 his laboratory burned down under mysterious circumstances. The results of historic period of work have been lost.
