Another space station orbited the earth recently:

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.
