The launcher preparation programme has not only involved validating the ability of the Aestus engine and EPS stage to carry out a totally new mission (nearly 200 ignition sequences were executed at Lampoldshausen under hot conditions over a broad temperature domain to ground qualify the Aestus engine), but has also led to development of a dedicated VEB, development of totally dedicated software and an exhaustive campaign to confirm the capability of the lower stages to carry an exceptional load in flight. It should be noted that, while lift-off mass of the payloads normally carried by Ariane is of the order of 8 to 10 tonnes, the ATV mission requires the launcher to place 20 tonnes into orbit!
Successful re-ignition of the Aestus engine was operated for the first time under actual flight conditions representative of the ATV mission during the Ariane 5 flight of October 5, 2007.
