The Atlantis space shuttle has arrived at the International Space Station on the final mission in America's space shuttle programme.
Astronauts made the shuttle do a back-flip so it could be checked for damage before parking up.
Atlantis will spend a week docked at the space station before returning to Earth.
The four astronauts on board have taken vital supplies into space, including enough food to last for a year!
During America's 30-year space shuttle programme, there have been 135 Nasa missions.
