ce cooperation at the occasion of the birth of the European Space Agency. I
n 1979, the first Ariane was a technical success. The evolution of the laun
cher and the creation of the company 'Arianespace', in charge of the produc
tion, the commercialisation of the launching and the operations of launchin
g have transformed this technical success into an economic success, since t
his company has kept 60% of the commercial market of launch services. (C) 1
