Nasa astronauts have completed the last ever space walk from a space shuttle.
During the six-and-a-half hour walk, they fixed some equipment to the outside of the station and picked up some broken machinery.
The four astronauts on board the Atlantis shuttle have taken vital supplies into space, including enough food to last for a year!
They'll then fill up with space station rubbish and discarded equipment, before returning to Earth next week.
Atlantis is on the last ever mission for a space shuttle. After that, all three shuttles will be put in a museum for people to look at.
