People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

Japan tests innovative magnetic tether for slowing space junk

RATE THIS! +33
Posted in Science on 10th Dec, 2016 11:58 AM by AlexMuller

Japan has launched a cargo ship which will use a half mile- (700m)-long tether to remove some of the vast amount of debris from Earth's orbit. The tether, made of aluminium strands and steel wire, is designed to slow the debris, pulling it out of orbit. The innovative device was made with the help of a fishing net company.

 

There is estimated to be more than 100 million pieces of space junk in orbit, including discarded equipment from old satellites, tools and bits of rocket. Many of these objects are moving at high velocity around the Earth at speeds of up to 28,000km/h (17,500mph) and could cause catastrophic accidents and damage to the world's orbital telecommunications network.
 
The junk has accumulated in the more than 50 years of human space exploration since the Soviet-launched Sputnik satellite in 1957. Collisions between satellites and the testing of anti-satellite weapons have made the problem worse.
 
The automated cargo ship - called Stork or Kounotori in Japanese - which is carrying the junk collector is bound for the International Space Station and blasted off from Tanegashima Space Center in the North Pacific.
 
Researchers say the lubricated, electro-dynamic tether will generate enough energy to change an object's orbit, pushing it towards the atmosphere where it will burn up.
 
A 106-year-old Japanese fishing net maker, Nitto Seimo Co, collaborated with Japan's space agency to develop the mesh material, Bloomberg reported last month.

It is about the time to tackle this estimated more than 100 million pieces of space junk in orbit, including discarded equipment from old satellites, tools and bits of rocket. Reply
