While doing an EVA on the ISS, Space Shuttle astronaut Suni Williams' camera broke free of its bracket and floated away from her into space.
It's below and ahead of the station, so it probably won't cause any trouble that way. I expect it'll fall into the Earth's atmosphere and burn up in the next couple of years. I haven't found any official word on that yet though.
However, bring on the beauty of that which is YouTube. You can see this event unfolding for yourself.
