It took more than 200 astronauts from 12 countries more than a dozen years to build the International Space Station (ISS). Satoshi Furukawa, an astronaut from Japan, matched that feat in just about two hours — and he did it all while aboard the orbiting outpost itself.
It helped that his space station was made out of LEGO.
“It was a great opportunity for me to have built the LEGO space station,” Furukawa, a Japan Aerospace Exploration Agency (JAXA) flight engineer, told collectSPACE.com in an interview after he returned to Earth. “I enjoyed building it.”
