Space junk: 17,000 So are the objects that you can fall on your head / Expansion / Most are Russians and Americans, but there are also Chinese and scrap some Spanish TV. The Survillance Space Tracking program (SST), which participates Elecnor, can locate and monitor hazardous waste and alert satellite operators.
The space objects have fallen recently in Murcia Spain and other area have revealed the abundance of “junk” there circling Earth. Although it seems a story, that space debris is not only a real threat to the safety of persons. It is also an economic problem of enormous dimensions.
A study by NASA and the European Space Agency, says there are currently about 17,000 cataloged objects more than 10 centimeters long circling our planet. Of these is tracked, explains Miguel Belló, managing director of Elecnor Deimos, the subsidiary of the Spanish group Elecnor satellites. “These are objects that can be seen,” says Belló, “In addition, there are hundreds of thousands of smaller objects”. It is estimated that there may be between half a million and a million floating objects in different orbits around the planet.
Most screwdriver floating space junk is junk that has been caused by the collision of satellites in disuse or as a result of explosions of rockets into orbit, or leftover rocket boosters. There are also complete satellites circling following decades after afford downtime. And even, “there is a screwdriver that once dropped an astronaut on a space mission,” says Bello. “We have located,” explains the director of Elecnor Deimos. This company participates in the Space Tracking Survillance program (SST), aimed at providing surveillance and monitoring space for localization and monitoring of hazardous wastes and warn satellite operators about the risks of collision. And also, the government calls on uncontrolled re-entries in the atmosphere and fall on Earth.
Although it is very difficult for these objects falling over people, is not impossible. “It can happen,” says Bello. Fortunately, over 90% of falling objects, burned in their friction with the atmosphere reminds Belló, addition, three quarters of the Earth are oceans or are uninhabited, so the odds of space debris be a threat to the population decreases. Whether fall above people is always the risk of nuclear components containing contaminants and maintain radioactivity. That, perhaps, is the greatest danger.
Elecnor compiles a list each week with objects that can fall from the sky. Through complex mathematical calculations, you can specify their orbits reach down to Earth and find out relatively precisely where they can fall if not disintegrate before. “It’s not easy, because we must bear in mind that objects moving at 25,000 kilometers per hour.” Elecnor, with satellite tracking facility in Puertollano (Ciudad Real), also has facilities for viewing objects in space, like a telescope, in the nearby town of Almodovar del Campo.
Just Like Gravity speed is what makes it dangerous space junk. The Gravity film, starring Sandra Bullock and George Cloony, picks it up perfectly. A tiny object the size of a fingernail, can drill to 25,000 mph, an astronaut suit or any new satellite to be launched into space.
other flying objects identified But who are these objects? How did they get there? Where are they exactly? Of the 17,000 other flying objects that are identified are 6,000 Russian bill, another 6,000 are Americans and has recently begun to proliferate the Chinese junk, with 2,500 pieces, largely from a single explosion of a device made by the Government Chinese two years ago to 800 kilometers up to display mode to demonstrate that it had advanced aerospace technology. Although Spanish is not abundant waste, the country also has some piece orbiting in space to drift. Specifically, the remains of INTASAT, the first Spanish artificial satellite, launched on November 15, 1974.
The garbage Earth Right now, 99% of objects orbiting the Earth ” worthless, “says Bello, who is a great promoter of space technology. The problem is that space has become a kind of gigantic dump that take care cost much. An example is the case with satellites into disuse. The owners could remove them from making space down to orbits closer to Earth until it attracts them and end up falling in the atmosphere and destroyed in a controlled operation. But depressing to have to maneuver them and that a large amount of extra fuel is needed. The company owns preferred to use the fuel for the satellite to continue operating a few months, instead of using it for the purposes of destruction.
A cemetery land 300 kilometers One solution would be to gradually lower the satellite into what has become known as the graveyard orbit. This is an orbit which lies about 300 kilometers from Earth and that, in principle, international agencies have recognized exclusive to deposit waste. The problem is that although there have been efforts to achieve an international consensus, each country has different rules about what to do with space debris. Some force out there once the satellite end of life. . Others do not
