Ariane 1
Ariane 1 was the first rocket in 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 satellites grew, Ariane 1 gave way to the more powerful Ariane 2 and Ariane 3 launchers.
== Vehicle description ==
Ariane 1 was the first launch vehicle to be developed by the European Space Agency. It was developed from the L3S Europa launch vehicle replacement design. The development of the vehicle was authorized in July 1973. The cost of program is estimated at 2 billion euros. With lift-off mass of , Ariane 1 was able to put in geostationary transfer orbit one satellite or two smaller of a maximal weight of .
The Ariane 1 was a four-stage vehicle (fourth stage put satellite from GTO to GEO is usually not counted as part of rocket, because it is included in 1.85 tons of payload). The first stage was equipped with 4 Viking engines developed by the Société Européenne de Propulsion. The second stage had a single Viking engine. The third stage had one LOX/LH2 bipropellant engine capable of a thrust of 7,000 kgf (69 kN). The fourth stage was powered by a single Mage-1 solid rocket booster producing a thrust of 20 kN.
This design was kept in the Ariane series until Ariane 4.〔 〕
