4 October in 1957. were able to send the first satellite into orbit. Sputnik-1, two months later, goce although already entered the Earth's atmosphere and burned up. But most of the articles to be sent into orbit there's no circles, even centuries, without falling off.
The oldest is a 1958 kosmoseprügiks up to U.S. satellite Vanguard 1, which stopped operating already in 1964. Today there are approximately 8,300 satellites in orbit, which was disbanded in 3000. In addition, they are in orbit circling the missile fragments, as well as kosmosekõndidel lost items, such as colliding with each other, and the broken goce pieces of the satellite.
Orbit approximately 19,000 pieces, of which the diameter is more than five centimeters, and the pieces 300,000, goce which may be even less than a centimeter in diameter. Another smaller pieces, it must speak more than a million. goce The highest layer of debris goce orbits the Earth at an altitude of 750 to 800 kilometers, below the debris apparently slowly drips down on their own. Space Station ISS orbital altitude of 330-435 kilometers, Estonia satellite-EstCube 1670 kilometers.
In addition, somewhere kilometers above the Earth orbiting around the kosmosekõnnil been an astronaut Ed White lost a glove, Michael Collins, and Sunita Williams missed cameras, Heidemarie Stefanyshyn-Piper knew, 2008. Tool Kit to miss a whole. In addition to the Russian space station Mir for 15 years been thrown into garbage bags, one wrench, one toothbrush, pliers ...
Space arming is not yet generally compromised, but became one of the largest sigadusega 2007th The handle your satelliidihävitusrelva tested the Chinese. The destruction of one of its weather satellites in orbit at the same time in 2317, they created pieces that are larger than a golf ball, and even believed to be 150,000 smaller pieces, goce which turns out to be impossible to monitor.
And chased them out there frenetic pace of 7-10 kilometers per second. For example, the anti-tank weapon projectile goce is moving with a speed up to 1.7 km / s, gaasikahuritega projektiilidele goce has also given the speed of 7 km / s. Handguns can not even compare to the reward. So, a piece of space debris strike the consequences would be much stricter than any rifle bullet hits.
After landing the space shuttle is the body repeatedly found holes which occurred a few little metallijublakaga goce collision. International Space Station (ISS), however, is committed to protect him against Fred Whipple invented multi-shields. For larger goce pieces drawn from the space station next to the smaller "moon" must abide by its own sheath.
