![]() Kessler, however, thinks that neither concept would be a total solution, even if they worked as planned. Two current possible ideas for cleaning up space debris are the use of powerful lasers, whose projected laser beams would push the space junk into lower orbits to be burnt up, and the creation of a matrix of nets to catch some of the space junk. ![]() Kessler believes that an increasing frequency of collision of space junk will create "a permanent belt of space debris" that would be so thick that it would be a hazard to any attempted launched rocket or satellite. International interest in cleaning up space debris has increased in recent years, especially since February 2009, when two artificial satellites collided at almost about 790 km over Siberia, creating over 1,000 pieces of space debris. However, usually an object of 10 centimetres or greater is considered "large". Astrophysicists and scientists have difficulty putting precise definitions to "large" space debris. Size of space debris can be as small as one centimetre. To cite a case, NASA does not annually spend any government funds with regard to the research and the cleaning up of space junk. Another factor to consider is that astrophysicists and scientists have been slow to address the topic. ![]()
