Launch history
The first launch was on December 24, 1979, and was successful. The second launch, in 1980, failed shortly after launch due to a combustion instability in one of the Viking first stage engines. The third launch succeeded in orbiting three satellites, and the fourth and last qualification launch was also a success.
During the next launch, the first commercial one, the rocket ceased functioning after 7 minutes of flight due to a turbopump failure in the third stage. After a complete review of the launcher, the next 6 flights were all successful.
The Giotto mission's spaceprobe was successfully launched on the tenth Ariane 1 (flight V14) on July 2, 1985.
The first SPOT satellite was put into orbit by the eleventh and last launch of Ariane I, which was on February 22, 1986.
