Astronaut Doug Wheelock checked in while on the International Space Station today, earning himself an oh-so-exclusive "NASA Explorer" badge. But Foursquare is also partnering with NASA to encourage all kinds of terrestrial space-knowledge exploration.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
