ADVISORY/ILS Proton to Launch Intelsat 903.
ADVISORY...for Saturday (March 30)
Payload: Intelsat 903 Loral 1300 platform Separated mass: approx. 4,726 kg (10,421 lbs) Launch Vehicle: Proton K/Block DM Weight at liftoff: 691,272 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: Saturday, March 30, 2002 Launch Window Opens: 10:25 p.m. Baikonur 8:25 p.m. Moscow 17:25 GMT 12:25 p.m. EST (USA) Launch Site: Baikonur Cosmodrome, Kazakhstan Launch Complex 81, Pad 23 End User: Intelsat, international satellite operator Satellite Manufacturer: Space Systems/Loral, Palo Alto, Calif. Launch Vehicle Khrunichev State Research and Production Manufacturer: Space Center, Moscow - Proton first three stages; RSC Energia, near Moscow - Block DM fourth stage Launch Services International Launch Services (ILS), McLean, Provider: Va. Satellite Use: Internet, broadcast, telephony and business services for Atlantic and eastern Pacific ocean regions Satellite Statistics: -- 4th satellite launched in Intelsat IX series -- Orbital location: 325.5 degrees East longitude -- 76 transponders at C-band (36 MHz equivalent units) -- 24 transponders at Ku-band (36 MHz equivalent units) -- Anticipated service life of 13 years Mission Profile: The Proton launch vehicle will inject the Intelsat 903 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 161-km (100-mi) circular parking orbit, inclined at 51.6 degrees. Then the "enhanced" three-burn Block DM will propel the satellite to its transfer orbit. 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 36,000 km (22,300 mi). Spacecraft Separation: Approximately 6 hours, 43 minutes after liftoff ILS Mission Statistics: -- 3rd ILS mission this year -- 1st ILS Proton mission this year -- 22nd ILS mission on Proton since formation of the U.S.- Russian joint venture in 1995 Live Broadcast: Satellite: Telstar 5, transponder 23, C-band Downlink frequency 4169 vertical Test signals to begin at 11:30 a.m. EST More Information: Live webcast and general mission information are 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.
