(London Telegraph) NASA does not need to travel to the stars to find new forms of life – it has discovered a new species of bacteria living in the special rooms used to build spacecraft.
The US space agency uses sterilized clean rooms to build spacecraft for missions to other planets to help avoid any contamination that may hinder the search for life.
These rooms are kept extremely dry, are cleaned with chemicals including bleach and have negative air pressure to keep out any contaminants.

Ultraviolet light and heat treatments are also used to kill off any life on objects that go in and workers are required to wear special suits.
