Ariane 5

The Ariane 5 measures up to 54 m (177 ft) tall and weighs about 710,000 kg (1.57 million lb). The rocket’s power sources consist of a liquid hydrogen/liquid oxygen core stage, an upper stage that burns UH25 and nitrogen tetroxide, and two strap-on boosters that burn HTPB solid fuel. Ariane 5 can deliver 18,000 kg (39,600 lb) into low Earth orbit. It can place either a single satellite weighing 6,800 kg (15,000 lb) or two satellites with a combined weight of 5,970 kg (13,200 lb) into geostationary orbit.
