NASA clean rooms breed hardy bacteria

Catalogue made of bugs that survive preparations for space.

The ultra-clean facilities used to assemble NASA's spacecraft are inhabited by some hardy bacteria, which could be hitchhiking their way to space.

Samples from NASA's Jet Propulsion Laboratory (JPL), Kennedy Space Center and Johnson Space Center, show the variety of bacteria that make it into the spaceship assembly areas despite the clean rooms used to build the craft in.
