Space Junk In Earth Orbit Now Worse Than Ever

Officials at NASA now say that the amount of "Space Junk" that is in Earth's orbit is now greater than ever before. They are currently tracking about 22,000 pieces of space debris that they categorize as "big objects," which are pieces of space junk that are larger than about one half of an inch, and countless thousands of smaller objects that are less than one half of an inch in size.
Since 1957 when the Russians launched the first satellite "Sputnik" mankind has been littering the orbit of the Earth with bits and pieces of debris from rocket launches and satellite launches. Much of the stuff over time falls back into Earth's atmosphere and is burned away but some debris achieves too high an orbit in space for that to happen and so it just circles around the Earth for years causing a hazard for space missions and expensive communications satellites. Even the International Space Station from time to time has to adjust its orbit in order to avoid a tracked piece of space junk from hitting it and causing devastating damage.
The amount of space debris increased greatly in 2007 when the Chinese government conducted an anti satellite weapons test. The Chinese launched a missile into orbit to destroy an old weather satellite. When the missile hit its target it shattered it into an estimated 150,000 new pieces of space debris.
