Douglas Wheelock, a NASA astronaut, just checked into the International Space Station. On Foursquare. In outer space. The feat netted him the NASA Explorer Badge, which I'm sure is very validating, you know, for a real astronaut.
Wheelock, aka @Astro_Wheels, is the Commander of ISS Expedition 25, a team comprising astronauts and cosmonauts from the US and Russia. His historic check-in earned him the NASA Explorer Badge, which terrestrial Foursquarers will be able to unlock by visting space-related sites here on Earth. All of this, of course, is very crazy.
