A team of Australian scientists is teaming up with NASA on a project that will use lasers to not only find and track space junk, but also destroy these orbiting hazards.
There's a lot of junk orbiting around our planet. Rockets and booster stages from satellite and spacecraft launches, dead satellites, garbage bags, cameras, tools, and even a toothbrush — these objects all travel around Earth at thousands of kilometres per hour. Added to that are all the tiny pieces of debris — nuts, bolts and fragments of damaged spacecraft and satellites that largely go unaccounted for because they're just too small to track.
"Without efforts to clean up the space junk, it could eventually become impossible to send satellites into space," Professor Matthew Colless, the director of Australian National University's Research School of Astronomy and Astrophysics at the Mount Stromlo Observatory, said in a statement.
