Introduction (space junk)

Just like e Messy teenager's bedroom, The space around earth is starting to get filled up with junk.  Ever since the earliest days of space exploration,  Debris has been left behind orbiting around the planet with human activity increasing in space, More and more debris has been left behind and it's now a real serious threat to orbiting spacecraft. 

The debris ranges in size from disused satellites down to tiny flecks of paint, And it's estimated there are over 170 million pieces of space debris orbiting around the planet. now some of the more interesting pieces of Junk includes gloves, Spanners, And even frozen clumps of urine dumped from orbiting spacecraft.

In fact, Apollo 9 Astronaut Russell Schweickart said the most interesting, Beautiful site in orbit is a urine dump at sunset. The debris could be travelling as fact as 8000 Meters per second. That's roughly 17,500 miles per hour, And this speed even a tiny piece of debris could rip through the spacecraft or satellite.

In February 2009, A decommissioned Russian satellite collided with a us communications satellite called Iridium 33, Completely destroying it and causing thousand of pieces more of space junk. Now, While this could have a huge collateral cost, The fear is the that a collision like this could cause a chain reaction creating more and more space junk, And this is called Kessler syndrome.

This was actually the basis of the 2013 film Gravity, And the fear is that actually this could come in to contact with spacecraft carrying astronauts. And this really does have the whole potential for the loss of the human life. NASA is tracking the 500,000 pieces of space junk the have the potential to damage or destroy orbiting satellites or spacecraft.

And the International space station can have it's orbit moved up and down to avoiding potentially damaging pieces of junk. Now nations are starting to look at ways of not just tracking these pieces but actually destroying them or returning them to earth. The Chinese government developed a method using missiles to destabilize the orbits of satellites, Return them to earth so they harmlessly burn up in the earth's atmosphere.

But the fear among other nations is that this method could be used to destroy working satellites that the Chinese government isn't in favor of  with civilization's dependence upon satellites for weather forecasting, GPS, Scientific research, Could the day come when civilization is brought to its knees by a tiny fleck of paint?

Space debris Efforts to clean up space

Around the earth today we have thousands and thousand of objects or particular round in the near friction less environment of the cold vacuum of space and that now is doing a big hazard to future spaceflight not just to robotic spacecraft but also to people working for example on the space station.

What we need to do is  to go in to space and start to clean it up the question is how to do that left to their own devices the satellites don't readily fall down who may take many tens if not hundered of years to fall down so we need to accelerate that process and here it's sorry we developed a technology to enable us to do that satellites which are in this wooden region of space what we call low earth orbit.

Remove debris was launched from cape Canaveral on a falcon nine spacecraft and was launched up to the ISS and the second of April then astronauts unpacked remove debris from it's container and put it onto a slide table that goes through an airlock through the international space station so we'll have a Cube sat which is released large target being inflated and then the net ejected and wrapping itself round the target and bringing the whole lot home.

The question is how to bring this debris down what we'll do is we'll deploy a large sail and this sail will drag against the residual atmosphere bringing energy out of the orbit bringing the satellite down lower and lower the course as it comes down lower the atmospheric density gets bigger and bigger so the effect really builds up and eventually when we're up at about a couple hundred kilometers 180 kilometers the frictional effect of the air rushing Byers is enough to heat us up to a temperature hotter than the surface of the sun in fact the satellite will completely vaporize just end up as a puff of gas.

Some 8,000 tons of space debris orbits the earth ranging from obsolete satellites to tiny flecks of paint the united states tracks 23,000 objects larger than about 10 centimeters ISA receives  the data on these objects and analyse them for any possible conjunctions with it's functioning satellites the requires are the one that if they get impacted will create a cloud of  molar Tabriz which in turn could hit other the breeze and days could start what is called the kessler syndrome.

A chain reaction which is not controllable the Prada space debris has to be fixed in two days first one we need to stop polluting and second way we have to remove the garbage if you want and deliveries at  ESA's tech center in the Netherlands engineer's are developing IDI orbit designed to capture an out of control satellite and remove it from harm's way it's  being tested using a robot and satellite model we use the camera which is mounted on the smaller robot arm to mimic to reproduce the motion of the satellite around the target the target satellite around the target.

The target satellite what we want to be to capture once we are sure we are moving like a single object we  are as if we were densely but without touching it each other we can move the robotic arm to grab the launcher adapter ring co which us easy to bring it down to the earth and destroyed in the reentry or in the south pacific ocean. Another  approach involves using nets to capture space junk so the concept is to let's say to mimic what the fishermen do on the sea and so to have a very large a net to stay away from our the breeze and med satellites that is tumbling and moving freely and then from that distance to keep our net and you just try to warp all over your satellites although Edie orbit is still in development ISA scientists will be closely watching a UK mission. Remove debris this will trial the net concept coming months using a test satellite launch from the international space station. In the mean time the priority is to make sure new satellites don't add to the problem ideally at the end of their lives.

Satellites are either parked in graveyard orbits or their course adjusted to re-enter the atmosphere this is an AIV supply ship burning a apart over a remote area of the pacific ocean but even with planned reentry's like this tough components in titanium and steel can survive to hit the earth there's only signal called quanta specifically right now we're trying to understand what happen to the materials. We use and then we'll see how we can improve them how we can work on the design and conception of the satellite how the different parts of the satellite break up in relation to each other in order to have a satellite which is safer at the end of its life and creates the smallest amount of debris on the earth issa supports and follows international guidelines to reduce space debris but it's up to all countries to work together to combat the problem with our increasing reliance on space dealing with debris is in everyone's interest.
