The space shuttle, Endeavour, has docked with the International Space Station on its final mission hundreds of kilometres above South America.
The $2bn NASA mission is aimed at attaching a telescope onto the space station to explore facts about the universe.
Endeavour is the second to last mission of the US shuttle program, which will end later this year after the final launch by the shuttle Atlantis.
The shuttle programme is being shelved to cut costs and from now on Russian spacecraft will be the only way to get to and from the world's orbiting research laboratory.
