Rosetta is lowered into position

High inside the Final Assembly Building, Rosetta was lowered into position on top of the Ariane 5 launcher. The large dish is Rosetta's 2.2-metre diameter steerable high-gain communications antenna. After launch, the antenna will swing into position away from the spacecraft, allowing the dish to be pointed toward the Earth during Rosetta's long mission, scheduled to end in December 2015.
