Today in 1969 was the first day off for the Apollo 11 astronauts in more than a month. Yes, they'd finished their moon landing weeks earlier, but they had to go into quarantine in case they'd picked up some "moon germs" that could lead to a plague on Earth. (Fortunately, they hadn't.) Plus: there's a new augmented reality tour of a church in Florence, Italy that was deconstructed in 1784.
