Scientists sound alarm over growing amount of junk in space

Discover Magazine quotes John Crassidis in a story about the increase of space junk. Crassidsis says most of the junk in space is due to the satellites and rockets that have been launched into space since the beginning of the space age in 1957. “The biggest contributor of debris is explosions in orbit, caused by leftover energy from fuel and batteries onboard satellites and rockets,” Crassidius states.
