Japan is preparing to launch a giant magnetic network to catch debris
The following month, the Japanese Space Agency (JAXA) will launch a space trawler – spacecraft that will haul a giant aluminum-steel network of orbiting the Earth, trying to catch debris, which orbit divorced just a huge amount . NASA tracks about 20,000 pieces of large (5 cm and more) orbital debris, but according to various estimates, floating in orbit around 500,000 elusive particles. If one piece gets into the ship, which is in orbit, the collision is likely, will have disastrous consequences (as in the movie “Gravity”) and starts a chain reaction that resulted in debris will be more.

If we do not collect orbital debris now, there is a possibility that one day the garbage becomes so dense that we could not leave the Earth’s surface without being broken up into fragments.

Working with orbital debris – is a relatively new area of ​​research – began after the Chinese anti-satellite missile test in 2007 and the collision of two satellites in 2009, one of which has been inactive since 1995. In both cases, formed a huge pile of orbital debris might one day “attack” and to other satellites. The International Space Station, due to its size and the presence of people, passengers, causing particular concern. As you see in the image, flying around the Earth too much junk with which to do something.

Fortunately, most of our space agency is currently working on some plan to clean up low-Earth orbit (LEO, where much of the debris flies) and geostationary orbit (GEO). NASA, for example, considered the idea of ​​a “laser broom” – terrestrial laser that shoots into space and removes debris from its orbit. Another option – to send another spacecraft that will strengthen small racket to the garbage and send it away. DARPA has proposed a draft Phoenix, which will take small satellites and send them into space to attach to the old inactive satellites. Small satellites will use old satellites reception antennas, reducing the amount of garbage (but not the amount of any rubbish floating in near-Earth space).

Method JAXA almost fantastic. Japanese Space Agency wants to run a dedicated spacecraft that will be pulled along electrodynamic net. To this end, JAXA has teamed up with Nitto Seimo, the company producing fishing tackle, to create a network of steel and aluminum wires. The network will produce an electromagnetic field which will attract debris. Once the network is filled with junk, it will be dropped from orbit and burn up in the atmosphere. The first version, which will be launched in February, will be 700 meters in length. If all goes well, the next one will have a length of 10 kilometers. Option JAXA, of course, leaves a lot of questions for discussion. Some researchers believe that the network will break from the stress itself becomes debris or accidentally catch operational satellite.

Also taken proactive measures: satellite manufacturers increasingly include features that allow satellites to go into orbit own burial (special orbit debris that does not interfere with satellites), or fall and burn up in the atmosphere.

If we just sit back, everything will happen as scripted Donald Kessler. In 1978 Kessler suggested that one day in low Earth orbit will be many objects that multiple collisions lead to new clashes, trash Weathertop and make space exploration and travel impossible. This scenario is also called effect Kessler. Hopefully, the space agencies of the planet Earth will solve this issue.
