The Odyssey Launch Platform
and the Sea Launch Commander have embarked on their transit to the Equator for
the launch of the Galaxy XIII/Horizons-1 satellite for PanAmSat Corporation
and JSAT Corporation. Liftoff is scheduled for September 30, in a 39-minute
launch window that will open at 9:03 pm PDT (4:03:00 GMT, October 1).

The Sea Launch vessels are sailing from Sea Launch Home Port, in the Port
of Long Beach, Calif., to the launch site on the Equator at 154 degrees West
Longitude. When they arrive, the launch team will initiate a 72-hour
countdown, ballasting the Launch Platform to launch depth and performing final
tests on the rocket and spacecraft. The three-stage Zenit-3SL rocket will
lift the 4090 kg (9,081 lb) Galaxy XIII/Horizons-1 satellite to geosynchronous
transfer orbit. This is the third mission Sea Launch is executing for
PanAmSat, including PAS-9 in July 2000 and Galaxy IIIC in June 2002.

The Boeing-built 601 HP spacecraft is designed to offer a variety of
digital video, Internet and data services to North America, Central America,
Alaska and Hawaii. The spacecraft’s Ku-band payload, designated Horizons-1,
supports the Horizons joint venture of PanAmSat and JSAT and is jointly owned
by the two companies. This venture provides expanded Ku-band services in
North America and extended services to Japan and Asia via a Hawaii-based relay
station. The C-band portion is known as Galaxy XIII and will be operated
separately as part of PanAmSat’s Galaxy cable neighborhood, which serves the
U.S. cable industry.

Sea Launch Company, LLC, headquartered in Long Beach, Calif., is a world
leader in providing heavy-lift commercial launch services. This multinational
partnership offers the most direct and cost-effective route to geostationary
orbit. With the advantage of a launch site on the Equator, the reliable
Zenit-3SL rocket can lift a heavier spacecraft mass or provide longer life on
orbit, offering best value plus schedule assurance. Sea Launch has a current
backlog of 15 firm launch contracts. For additional information and live
