Space Junk
Isaac Asimov's 21st Century Library of the Universe: Past and Present
What happens to all those pieces of rockets and space shuttles that break off during space missions? Do they ever come back to Earth or do they float eternally in outer space? Space Junk investigates humankind's impact as we continue to leave not only our footprints on the Moon but our trash in outer space.
