This activity took place in the Ariane 5 Final Assembly Building at Europe's spaceport at Kourou in French Guiana. Here an overhead crane hoisted Rosetta up inside the Final Assembly Building. This underside view shows the compact dimensions of the EADS Astrium-built spacecraft, which accommodates the scientific payload and subsystems in a 12-cubic-metre platform. Rosetta will start its 10-year journey to Comet 67P/Churyumov-Gerasimenko with 1650 kilograms of propellant on board, accounting for more than half its mass at lift-off. Once in the vicinity of Comet Churyumov-Gerasimenko, the spacecraft will spend more than six months mapping and observing the comet.
