It's busy in orbit

Since the advent of the space-age over five decades ago, more than thirty-five thousand man-made objects have been cataloged by the U.S. Space Surveillance Network. Nearly twenty-thousand of those objects remain in orbit today, ninety-four percent of which are non-functioning orbital debris. These figures do not include the hundreds-of-thousands of objects too small to be cataloged, but still large enough to pose a threat to approximately nine-hundred operational satellites in orbit around the Earth. In addition, collisions between debris objects could potentially lead to a continuously growing debris population, thus increasing the risk to operational satellites.
