The pentagon wants to clean up the space debris that orbits the earth. Most of this stuff isn't worth the cost it took to put it in the air to begin with now; mainly because it doesn't work anymore. There isn't any word on how the Pentagon will clean up this space junk, or if it will involve other nations than just the U.S.
“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,” the agency notes. “Nearly twenty-thousand of those objects remain in orbit today, ninety-four percent of which are non-functioning orbital debris.”
