Next year will complete six decades of space travel. Earth is being orbited by one hundred million pieces of debris because of this exploration.

This debris includes everything from particles of paint and flecks of plastic to the tool box that was misplaced by a US astronaut who visited space in 2008 to the huge satellite launched by the European observation that is almost equal to the size of a bus.

Twelve years ago, Australian Archaeologist Dr. Alice German started wondering about the effect this space junk can have on Earth in the coming years. Space junk makes space more dangerous. According to ABC News, newly launched and working satellites would have to dodge the ones that are no longer useful.

When this space debris collides with one another, it converts into further smaller parts which can damage or destroy the working satellites if they collide with them.

There is a chain reaction known as Kessler Syndrome, which has the potential to destroy satellites valued at more than $1 trillion in a week and leave Earth covered in a lot of debris that it will be harder to leave the planet. Dr. Gorman suggests that the problem of getting rid of the space junk is not technical, it's legal and diplomatic.

According to The Atlantic, a special type of satellite with the potential to knock out space junk of orbit is being developed by Japan to be launched next year. However, there are a few satellites that need to be protected while cleaning space junk.

Those are Vanguard 1, Asterix-1, Australis-Oscar 5, TRAAC (Transit Research and Attitude Control, Syncom 3.

Dr. Gorman does not want these satellites to be brought back, and neither does she want them destroyed. According to her, they should be left where they are.
