By some estimates, about 3,000 dead satellites are orbiting Earth, and around 34,000 pieces of space junk have been left behind by humans. Wherever humans go, we always leave a trace.
And it’s an even bigger problem in space because it takes much longer to decompose and does nothing but muck up the place, says Jack Gabel, an associate professor of physics at Creighton University in Omaha, Nebraska.
As humans go back to the moon and aim to travel to Mars, the more people that visit space, the more likely they are to end up dying there. Which brings up the question, what would happen to those bodies in space?
