Arianespace launched at 10:32 a.m. local time the satellites ECS-2 and Telecom I aboard an Ariane vehicle from Kourou, French Guiana. The first data received from both satellites showed satisfactory behavior. They were injected into an orbit with provisional parameters of 199.02-kilometer perigee, 36,091.00-kilometer apogee, and 6.98 ° inclination.
This 10th Ariane launch was the first flight of an Ariane 3 version of the vehicle, whose main characteristics were a higher thrust of the Viking first and second stage, a stretched third stage; greater 'liquid oxygen and liquid hydrogen tank capacities, leading to an increased flight time by approximately 30%; and the addition to the first stage of two strap-on rocket boosters.
Ariane 3 could carry 2,580 kilograms into geostationary transfer orbit. (ESA Release Aug 4/84)
