With An Eye To Mars, NASA is Testing its Astronaut Twins | Science | Smithsonian – This so amazingly cool. I had no idea that Mark Kelly’s brother was an astronaut, much less that he was an identical twin. It’s like the perfect guinea pig setup! Can’t wait to see what the results are.

This somewhat related story about twins going into space made me LOL though. The Winklevi used bitcoin to book a space trip. OF COURSE THEY DID.
