Nasa emails spanner to space station

Astronauts on the International Space Station have used their 3-D printer to make a wrench from instructions sent up in an email.

It is the first time hardware has been "emailed" to space.

Mike Chen, founder of Made In Space, the company behind the 3-D printer, said: "We had overheard ISS Commander Barry Wilmore mention over the radio that he needed one, so we designed one in CAD and sent it up to him faster than a rocket ever could have."
