Telstar 402 was successfully launched into space on September 9, 1994, by means of an Ariane-42L vehicle from the Kourou Space Center, French Guiana. It had a launch mass of 3,775 kg. The satellite was lost shortly after launch due to an explosion that occurred in the propulsion system that was caused by leakage of hot gases.[2]
