The launch of Sputnik I and Yuri Gagarin, the first human being in space, marked the beginning of space exploration and the beginning of a new and unfamiliar type of pollution.

          Satellites, solar panels, rocket bodies and fragments from space shuttles that are floating in space and are no longer functional are considered space debris. This pollution of man-made objects in space affects us here on Earth as well and will continue to affect us in future travel. In 1978, the Soviet Union Kosmos 954, which contained a nuclear power source, reentered over Canada and left debris over an area the size of Austria. In 1969, five Japanese sailors were injured by pieces of space debris that hit their ship. The largest piece, weighing one thousand pounds, landed in Australia in 1979.

          Many solutions are being considered by scientists and engineers. However, the challenge to finding a solution lies within all of the nations which take part in the space exploration.
