When you think of the International Space Station — that huge floating laboratory cruising through Earth's atmosphere that has housed dozens of different astronauts and cosmonauts over the years — what image does your mind paint? If it's a picture of pristine, almost clinical cleanliness, far away from the grime that you already know covers your kitchen counters and couch cushions, you should think again.
A new study published in the journal PeerJ reveals that the inside of the International Space Station is actually teeming with microbial life, and now after 17 years in use and without a single housekeeping visit, as many as 4,000 or more species of microbes can now be found inside. It might sound mighty nasty, but believe it or not, it's actually good news.
