Space junk can destroy satellites, scientists say

“The problem of space debris is getting worse every year,” Ben Greene, head of the Australian Center for Space Research, told AFP.

Some 170 million pieces of debris or “space debris” are currently in orbit and only 22,000 Earth are being tracked, said Greene, who is organizing a conference between international space science in Canberra.

“We lost three or four satellites a year to the collision of space debris. We are very close, according to NASA estimates, of five to ten years to lose everything,” said M. Greene, adding that “an avalanche catastrophic collisions Could quickly destroy all orbiting satellites, it is now possible. ”

Greene suggests that such collisions can jeopardize the global economy, which shows the example of satellite dependence in Australia.

“The Australian economy is totally space dependent,” said M. Greene. “We are a large country with few people and the only way to treat it, whether with surveillance, security and search and rescue, comes from space.”

A major collision of space stress is “inevitable,” if the problem is not addressed properly, space junk expert Moriba Jah University of Texas, who joined the Canberra conference told the Australian Broadcasting Corporation.

“You drove on the highways here when you have a lot of fog or mist, and you have to go very slowly, and not really know what’s around you.” It’s the perfect analogy with space now, “said Jah.

NASA debris defined as “any artificial object in orbit around the Earth that no longer serves a useful function.” Such space freedom can move at speeds up to 27,000 km / h, “fast enough for a relatively small piece of orbital debris damage from a satellite or spacecraft,” according to NASA.

NASA says about 500,000 pieces of debris are being processed, while more than 20,000 fragments are “larger than a baseball orbiting Earth.”

It may even be a potential hazard to the International Space Station (ISS) as well as several spacecraft and shuttles with humans overseas.

Proper removal of the “waste” space has become a more important concern because the simple act of throwing objects away from the ships has created a lot of space debris.

In February of this year, NASA astronauts dropped a capsule for the ISS waste by a ton and a half in what looked like the largest example of sand in space.
