Space Junk- A threat for satellites and economy


Pollution is an inevitable threat to this world from an elongated time period, and now the space too is facing the same menace, as the junk in the space has become a major problem for all the satellites to work properly.

Space is no more pollution free and the sources from the NASA (National Aeronautics Space Administration) claimed that around 170 million pieces of junk are now circling in the orbit of the Earth. This wreckage can lead to a ‘catastrophic avalanche of collisions’.

This can utterly destroy the working satellites in the space plus it is a danger for the economy of the world as society heavily depends upon these satellites for navigation and communication processes.

The satellites in the space are also directing the key-industries such as finance, transport and energy. For instance, if the satellites get damaged then the consequences will be quite severe.

The junk in the space is usually left behind after the space missions, the trash pieces can be as minute as flake of paint or can be as huge as a spent rocket stages.

But the fact is only 22,000 pieces are tracked and even the tiny pieces from the junk can badly damage the satellites as the space junk is travelling at the high speed of 27,000kmh.

According to Ben Greene (Head of Australia’s Space Environment Research), “We’re losing three or four satellites a year now to space debris collision. We’re very close, NASA estimates, of within five to 10 years of losing everything.”

“The Australian economy is entirely dependent on space,” Greene said. “We’re a big country with few people and the only way we can service it, whether it’s with surveillance, safety or search-and-rescue, is from space.”

Greene explained in the conference how dangerous this collision can be by giving the example of Australia whose economy absolutely depends upon the space. He also stated, The space junk problem has been getting worse every year.”

He also threw the light on some facts, in the conference as he mentions, “We’re losing three or four satellites a year now to space debris collision. We’re very close, NASA estimates, of within five to 10 years of losing everything.”

In the interim, the space trash disposal has become more significant after this warning given in the summit which held on Wednesday.

From the University of Texas, Moriba Jah also joined the conference, according to him, “You’ve driven on the roads here when you have a lot of mist or fog, and you have to go really slow, and you just don’t know what’s really around you. That’s the perfect analogy to space right now.”

This is a horrific picture drawn by Jah of the space, after such statements the responsible authorities should take necessary steps to solve this huge problem.

The largest instance of littering held this year in space when the astronauts dumped the trash (a tone and half capsule) out of the ISS.  This is also a potential hazard for the infrastructure of the space costing $700 millions.

 Even the scientist are working and developing such technologies which can track the debris so the spacecraft could easily move around them

But it is implied that if this major collisions takes place then it will turn out to be calamity for the whole world and it will devastate the satellites and thus the economy of the world will definitely collapse.
