"Amazingly, some of the bacteria survived. The population is strong and growing. That’s pretty impressive, when you consider it was exposed to near-vacuum and subarctic temperatures for over twenty-four hours. My guess is pockets of ice formed around some of the bacteria, leaving a bubble of survivable pressure inside, and the cold wasn’t quite enough to kill them. With hundreds of millions of bacteria, it only takes one survivor to stave off extinction. Life is amazingly tenacious. They don’t want to die any more than I do."
