This graphic of orbital debris, or “space junk" (any human-made object in orbit around the Earth that no longer serves a useful purpose) comes from 2009. The same year, a US communications satellite owned by a private company, Iridium, collided with a non-functioning Russian satellite. The collision destroyed both satellites and created a field of debris that endangered other orbiting satellites. Credit: NASA illustration, courtesy Orbital Debris Program Office.
