Sounds impossible, but the interview clip at BBC seems real. The experiment by Karen Olsson-Francis, Charles Cockrell and colleagues at the Open University in England was intended to see which, if any, microbes could survive in space.
The team took a chip of limestone from a cliff in a town called Beer in Devon that had microbes growing in the rock. They busted it into bits, and put the little bits on disks that were flow up to the space station and attached to the outside of the capsule. They were left for 553 days. When the chips got back to the lab, they were put into a growth medium in a tube. After awhile, the liquid turned green. Dr. Cockrell said there was only one survivor--a blue-green algae that one researcher in Redorbit's story said "resemble closely a group of cyanobacteria known as Gloeocapsa… They have a thick cell wall and this could be part of the reason they survived so long in space."
These may be the most extreme conditions ever for bugs that have been studied---intense UV, no air, no water, and really chilly. The idea, the scientists said was not only curiosity about extreme conditions, but if these bugs can really do this, why not start thinking about bringing them to other planets to produce oxygen for colonists? Be difficult to do the environmental impact statement on that one.
