A fourth attempt to launch the nation's first geostationary ocean weather-communications satellite, Chollian, will take place Sunday morning.

Arianespace Chief J. Y. Legall said that based on launch simulations conducted in Paris, the launch should be possible. Arianespace is a contracted launch services provider.

Arianespace will therefore attempt to launch the Ariane rocket, which will carry the Chollian satellite, between 6:41 a.m. and 7:45 a.m on Sunday (KST).

Although the Chollian was originally scheduled for launch on June 24th, it was delayed due to the detection of a pressure problem in the first phase and upper section of the Ariane rocket. On June 25th, the launch was stopped twice with the first taking place just 17 seconds before blastoff. The countdown was restarted again only to be halted with 16 seconds remaining.

If the launch is successful, Chollian will provide communications, maritime and climate data from geostationary orbit. It will remain in orbit for the next seven years at an altitude of 36-thousand kilometers.
