Hang Woon Lee, director of the Space Systems Operations Research Laboratory at WVU, said a junkyard of human-made debris, including defunct satellites, is accumulating around Earth. The more debris in orbit, the higher the risk that some of that debris will collide with manned and unmanned space assets. He said he believes the best chance for preventing those collisions is an array of multiple lasers mounted to platforms in space.
“That increased population of objects heightens the risk of collisions, endangers manned missions, and jeopardizes high-value scientific and industrial missions,” Lee said. He added that collisions in space can trigger a domino effect called the “Kessler Syndrome,” which induces a chain reaction increasing the risk of further collisions, “making space unsustainable and hostile.
