Last week, on the 10th of February, there was collision between two satellites. Apparently, this was the first major, unintentional collision in space involving a Russian satellite, which was no longer functional and a US owned, data communication satellite in full service at the time of the crash. This encounter, which happened over Siberia, produced debris, that could potentially pose danger to other objects that are in orbit around the Earth.
Interestingly, while looking for more information about satellites and man-made objects in space, I stumbled upon a very fascinating article and was very surprised about the content. As seen on the picture, there are thousands of man made objects orbiting the Earth, some of them loose debris and junk. Few of the more unusual articles floating around are a camera, a glove and some numerous wrenches and screwdrivers, all lost by astronauts during space walks. Al the space junk put together would produce a weight of about 11 million pounds here on Earth. Amazing!
Overall, NASA is apparently tracking more than 500 pieces of debris, as the floating garbage might pose a threat to the International Space Station or complicate the shuttle launch.
