   Ariane 5 - Summary
space.gif (43 bytes)

An Ariane 5 failed in a launch attempt of two satellites from Kourou, pad ELA 3, at 2158 UTC on July 12 possibly resulting in a US$1 billion loss. However, a propulsion failure in the rocket's upper stage resulted in a 592 km by 17,528 km orbit, inclined 2.9 degrees to the equator. Telemetry from the rocket indicated the vehicle had achieved a maximum velocity of just over 8 km/sec. The speed should have been about 9 km/sec at spacecraft deployment. The two satellites aboard the Ariane 5 were Artemis, and BSAT-2B. Given the low orbit, it is not known if the spacecraft have enough fuel to reach their final destinations. The Artemis satellite has two reignitable engines while the Japanese satellite has only one engine which can be switched on only once. Even if the satellites can be maneuvered into the correct orbit the spacecraft will have significantly reduced life-spans. ArianeSpace is working to do all they can to recover the satellites and see what kind of operations are possible to recover the satellites and rectify this. Arianespace has launched an investigation into the mishap to determine what caused the problem.
