ILS Proton to Launch EchoStar VIII 08-15-2002
Payload: EchoStar VIII Loral 1300 platform Separated mass: approx. 4,660 kg (10,270 lbs) Launch Vehicle: Proton K/Block DM Weight at liftoff: 691,000 kg (1.5 million lbs), including payload Height: 57.2 m (187.7 ft) Payload fairing: 4.35 m (14.27 ft) diameter Launch Date: Tuesday, Aug. 20, 2002 Launch Window Opens: 11:15 a.m. Baikonur 5:15 GMT 1:15 a.m. EDT (USA) 11:15 p.m. Aug. 19 MDT Launch Site: Baikonur Cosmodrome, Kazakhstan Launch Complex 81, Pad 23 End User: EchoStar Communications Corp., Littleton, Colo. Satellite Manufacturer: Space Systems/Loral, Palo Alto, Calif. Launch Vehicle Manufacturer: Khrunichev State Research and Production Space Center, Moscow -- Proton first three stages; RSC Energia, near Moscow -- Block DM fourth stage Launch Services Provider: International Launch Services (ILS), McLean, Va. Satellite Use: High-powered direct broadcast satellite to enhance services for DISH Network(TM), EchoStar's state-of-the-art DBS entertainment service Satellite Statistics: -- 8th satellite in EchoStar constellation -- Orbital location: 110 degrees West longitude -- Anticipated service life of 15 years Mission Profile: The Proton launch vehicle will inject the EchoStar VIII satellite into geosynchronous transfer orbit. The first three stages will use a standard ascent trajectory to place the Block DM upper stage with the satellite into a circular parking orbit of 160 km (100 mi), inclined at 51.6 degrees. Then the Block DM will ignite three times to propel the satellite to a transfer orbit of 4,300 km x 35,786 km (2,670 mi x 22,300 mi). Following separation from the Block DM, the spacecraft will perform a series of liquid apogee engine burns to raise perigee, lower inclination and circularize the orbit at the geostationary altitude of 35,786 km (22,300 mi). Spacecraft Separation: Approximately 6 hours, 36 minutes after liftoff ILS Mission Statistics: -- 5th ILS mission this year -- 3rd ILS Proton mission this year -- 2nd ILS mission for EchoStar in 6 months -- 24th ILS mission on Proton since formation of the U.S.-Russian joint venture in 1995 Live Broadcast: Galaxy 9, transponder 3, C-band, at 127 degrees West Downlink frequency 3760 MHz vertical Test signals to begin at 12:30 a.m. EDT More Information: Live webcast and general mission information will be available on the ILS web site at www.ilslaunch.com. Launch status updates are available on the ILS U.S. domestic Launch Hotline at 1-800-852-4980.
