He is "the first human to ever use a location-based service from space," wrote Foursquare's Eric Friedmon on the company's official blog.
For his crowning achievement, Wheelock received the one-of-a-kind NASA Explorer badge for his Foursquare profile.
In a move to regain popularity and wonder from the American public, NASA has been on a social media binge over the last several months, increasing its presence on Facebook and Twitter and even setting up its own official Foursquare account.
Additionally, last year the first official Tweet from outer space was posted, but something about actually using a location-specific app from space seems way cooler.
NASA did not have an official comment on the achievement, but they're probably planning something else exciting. We now just have to await when Google Street View goes to the moon.
