Earth Orbiting debris starting to impede Space Exploration programs

Japan’s H-2A rocket that blasted off on May 18 sent a Japanese satellite, Shizuku, and a South Korean satellite, Arirang-3, into orbit but it has also left behind space junk, the accumulation of which is starting to create big problems above Earth's atmosphere.

The amount of space debris has steadily increased since its start on Oct. 4, 1957, when the Soviet Union launched Sputnik 1, the first artificial satellite to enter Earth orbit.

Now that India and China are testing space systems, the "garbage problem" could rise at an explosive rate.

Countries are now trying to figure out ways to take care of the problem, but progress has been slow.

"We know that it will eventually impede the development of space, but if we just leave space debris out there anyway, then some day we won't be able to go into space anymore and our development there will hit a brick wall," said Seishiro Kibe, director of the Innovative Technology Research Center of the Japan Aerospace Exploration Agency (JAXA).

An estimated 22,000 pieces of debris with a diameter of 10 centimeters or more are floating around in space. Information, such as orbital path, size and origin, is known for about 16,000 of them.

There are also about 1,000 satellites in operation. The continued accumulation of space debris could interfere with the satellites' orbital paths, leaving them nowhere to operate.

Debris has always been a part of space development and will continue to be so but nations participating in space programs need to take responsibility for the disposal of there waste products, just as on Earth.
