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.
