Ariane versions

The several versions of the launcher include:
  • Ariane 1
    Ariane 1
    Ariane 1 is the first version of the Ariane launcher family. Ariane 1 was designed primarily to put two telecommunications satellites at a time into orbit, thus reducing costs. As the size of the satellites grew Ariane 1 gave way to the more powerful Ariane 2 and Ariane 3 launchers.- Vehicle...

Ariane 5 is a nearly-complete redesign. The two storable lower stages are replaced with a single, cryogenic core stage. This simplifies the stack, along with the use of a single core engine (Vulcain

). Because the core cannot lift its own weight, two solid-fuel boosters are strapped to the sides. The boosters can be recovered for examination but are not reused. The upper stage is storable and restartable, powered by a single Aestus engine.
