The Brand New Made-in-Space FrontierWhat happens when you're 220 miles above Earth on the International Space Station and you need a tool you don't have? You can print one yourself. In 2014, American astronauts for the first time printed a tool -- a ratchet wrench -- using a design file sent from NASA on the ground to the 3D printer spinning about in space. The feat was only the first step to much larger miracles in space.
