The US space shuttle, Atlantis, has landed at the Kennedy Space Centre in Florida, after a 12-day resupply mission to the International Space Station.
It was the third-to-last space journey for the shuttle programme, which has been operating for 25 years.
NASA is retiring the shuttle fleet for cost and safety reasons. Russia's Soyuz ships will take over most of the supply trips to the ICC.
NASA's other two space shuttles, Discovery and Endeavour, will make their final flights in September and November.
