[October 19 AFP] The European Space Agency (European Space Agency, ESA) announced on the 18th that the artificial satellite “GOCE” (Gautier) launched in 2009 may fall with a “one of these days” fuel piece, in order to observe the gravitational field of the earth.
However, it is said that there is almost no danger to man.
According to a ? satellite employment person in charge, Mr. Christoff Staiger (Christoph Steiger), fuel goes out within several weeks and Gautier is expected that it becomes 40?50 fragments and a total of 250 km falls to the earth.
According to ? and the said person, although Gautier’s fuel tank pressure will be zero by October 26, an engine may stop before it.
“At present, such a thing cannot predict whether it generates in which position.
It is said that however, it can predict correctly if the point which reenters an earth’s atmosphere is approached.”
? and also the said person “the probability that the space debris made artificially will rush into the atmosphere, and will collide with it is 65,000 times as low as the probability struck by thunder.
It is being explained that moreover, it is 1,500,000 times as low as the probability that it is killed in the accident which occurs in a house, such as falling down the stairs.”
