Sea Launch Initiates Countdown for the Launch of Galaxy 18
Long Beach, Calif., May 19, 2008 – The Sea Launch team arrived at the launch site in the Equatorial Pacific over the weekend and initiated a 72-hour countdown, in preparation for the launch of Intelsat’s Galaxy 18 satellite on Wednesday, May 21. Liftoff is planned at 2:43am PDT (9:43 GMT), at the opening of a two-hour launch window.
Upon arrival at the launch site, at 154 degrees West Longitude, the team began ballasting operations to bring the platform to launch depth. A final series of tests on the launch system and the spacecraft are now underway. Prior to fueling operations, the platform will be evacuated, with all personnel safely positioned on the ship, four miles from the platform. An hour after liftoff, a Zenit-3SL vehicle will insert the 4,642 kg (10,234 lb) Galaxy 18 satellite into geosynchronous transfer orbit, on its way to a final orbital location of 123 degrees West Longitude.
Built by Space Systems/Loral (SS/L), the 1300-series hybrid spacecraft, carries 24 C-band and 24 Ku-band transponders, to provide advanced television, data and telecommunications services to Intelsat customers in North America, Hawaii and Puerto Rico. This spacecraft is designed for a 15-year service life on orbit. It is the 6th mission Sea Launch will execute for Intelsat and the 7th mission with a spacecraft built by SS/L.
Sea Launch will provide live coverage of the Galaxy 18 mission via satellite and on its website, beginning at 2:30am PDT (9:30 GMT) on May 21. Live streaming video will be posted at: Sea Launch Webcast. Transponder coordinates for downlinking the satellite feed are provided at: Sea Launch Television Broadcast Downlink Information.
About Sea Launch Company
Sea Launch Company, LLC, headquartered in Long Beach, Calif., offers the most direct and cost-effective route to geostationary orbit for commercial communications satellites. With the advantage of a launch site on the Equator, the robust Zenit-3SL rocket can lift a heavier mass or provide longer life on orbit, offering best value plus optimized spacecraft orbital delivery. Sea Launch also offers launch services for medium weight satellites on the Land Launch system, originating from the Baikonur Space Center in Kazakhstan.
