 Mission: Galaxy 16

 

Sea Launch Company successfully launched PanAmSat’s Galaxy 16 communications satellite on June 18, 2006. Early data indicated the spacecraft was accurately positioned and in excellent condition.

A Zenit-3SL vehicle lifted off at 12:50 am PDT (07:50 GMT) from the Odyssey Launch Platform, positioned at 154 degrees West Longitude in the equatorial Pacific. All systems performed nominally throughout flight. The Block DM upper stage inserted the 4,640 kg (10,229 lb) Loral 1300-series spacecraft, to geosynchronous transfer orbit (GTO), on its way to a final orbital position of 99 degrees West Longitude. A ground station at Hartebeesthoek, near Pretoria, South Africa, acquired the first signal from the satellite shortly after spacecraft separation.

Payload - Galaxy 16

Built by Space Systems/Loral (SS/L), the 1300-series spacecraft, weighing in at 4,640 kg (10,229 lb), carries 24 C-band and 24 Ku-band transponders, primed to meet the needs of a variety of broadcast customers in the continental United States, Alaska, Hawaii, Mexico and Canada. Galaxy 16 is the fourth spacecraft Sea Launch will orbit for PanAmSat. While it is designed for a 15-year lifespan, Sea Launch’s direct insertion into equatorial orbit is expected to yield additional years of fuel life.

PanAmSat Corporation is the premier provider of global video and data broadcasting services via satellite. PanAmSat's global network of satellites and fiber connectivity provides unparalleled coverage of the Americas, Europe, Africa, the Middle East and Asia. This global network enables customers to reach millions of people covering vast geographic areas or offers them the ability to target specific groups in cities, countries or regions.

 Mission Profile

button to return to top of page

From its equatorial launch site at 154 degrees West Longitude, a Zenit-3SL launch vehicle lifted the 4,640 kg (10,229 lb) Galaxy 16 spacecraft to geosynchronous transfer orbit, on its way to a final orbital location at 99 degrees West Longitude.

Lifting off from the Odyssey Launch Platform, a Zenit-3SL rocket began its ascent phase of flight. The first stage of the vehicle separated two-and-a-half minutes after liftoff, and the protective payload fairing jettisoned 75 seconds later. Following a six-minute burn, the second stage separated from the Block DM upper stage. The Block DM operated for seven minutes and then shutdown for a 30-minute coast period. The Block DM burned a second time for four-and-a-half minutes. Following the second burn, and another 10-minute coast, the spacecraft separated over the Democratic Republic of the Congo in Africa. The Hartebeestok ground station at Pretoria, South Africa, acquired a signal from the spacecraft after spacecraft separation.
