A amount of space debris in Earth orbit has led experts in Switzerland to develop a project that aims to build a "satellite-janitor." Scientists at the Ecole Polytechnique Fédérale de Lausanne, in Switzerland, plans to release the device, called CleanSpace One in five anos.Com up an estimated 10 million Swiss francs (about $ 18 million), the CleanSpace One will be the first to reduce space pollution.
Swiss experts say there are about 16,000 objects with diameter greater than 10cm in Earth orbit - enough to cause an accident with satellite service or manned aircraft.
The U.S. space agency (Nasa) monitors larger pieces of junk orbiting the Earth. Besides them, hundreds of thousands of smaller pieces take risk to satellites and space missions.
The initial mission was designed to collect one of the first two satellites sent into space by Switzerland, both out of use - SwissCube, placed in orbit in 2009, and Tlsat, which became active in the year seguinte.Para collect the retired satellites, the "janitor" is launched into space and will have to correct his course toward the alvo.A captures will occur when the objects are sailing at a speed of about 28,000 km / h at an altitude between 630km and 750 km.
Equipped with arms that resemble tentacles, the CleanSpace One will embrace the other satellite and bring it back to the atmosphere, where both enter into combustion.
In the future, scientists plan to bring more space junk to Earth.
The amount of space junk in orbit requires the International Space Station (ISS acronym in English) to adjust your route frequently to avoid collisions.
However, the risk is increasing, according to Swiss scientists, which justifies the enormous amount of space insurance sector - currently estimated at U.S. $ 20 billion.
In February 2009, the U.S. satellite Iridium-33 exploded after colliding with the abandoned Russian satellite Cosmos 2251, adding more waste into orbit.
