Dangerous space junk accomplished stage Unknown6:28 AM 0 comments

Experts in the United States warned NASA that the amount of space junk in Earth orbit has reached a dangerous stage.

Report prepared by the National Research Council states that garbage can cause leaks in spacecraft or destroy satellites.

"The amount of junk orbiting Earth could collide assessed, which in turn will increase the number of waste fractions. It's all increase the risk of damage to aircraft, spacecraft," the report said.

Efforts to reduce the amount of waste space in recent years suffered a setback due to several factors.

In 2007, China conducted a weapons test by destroying satellite antisatelit no longer in use in space.

This test produces no less than 150,000 satellite fragments with a size of about 1 cm.

Two years later, the two satellites, one of which is still active, collided in the orbit and increase the amount of waste fractions in the sky.

"The two events immediately doubling the small fragments in Earth orbit. Cleanup efforts we did in the last 25 years to be wasted," said Donald Kessler, one of the experts at the National Research Council.

International Space Station (ISS), orbiting the Earth with a speed of 28,164 km / hour, sometimes also have to maneuver to avoid collision with space debris.

Last June, a few shards almost ran into the ISS, even had time to make the six crew members entered the rescue capsule and prepare evacuation to Earth.

"The situation is critical," said Kessler, a former NASA scientist is.

National Research Council called for the preparation of international rules to limit the space garbage.

It also calls for more research to find effective ways to clean the air from waste.
