Proton Launch Advisory: W3A |
| Payload: W3A satellite Eurostar E3000 platform Separated mass: approx. 4,250 kg (9,370 lbs) Launch Vehicle: Proton M/Breeze M Weight at liftoff: 691,272 kg (1.5 million lbs), including payload Height: 61 m (200 ft) Launch Date: March 16 (Baikonur) March 15 (GMT, U.S.) Launch Window Opens: 04:06 a.m. Baikonur 23:06 GMT 6:06 p.m. EST Launch Site: Baikonur Cosmodrome, Kazakhstan Launch Complex 81, Pad 24 End User: Eutelsat, Paris Satellite Manufacturer: EADS Astrium, Toulouse, France Launch Vehicle Manufacturer: Khrunichev State Research and Production Space Center, Moscow Launch Services Provider: International Launch Services (ILS), McLean, Va. Satellite Use: Largest satellite launched to date for Eutelsat. Ku- and Ka-band frequencies and Skyplex on-board processing to provide direct-to-home, video, data and broadband services in Europe, Middle East and Africa. Satellite Statistics: 58 transponders (50 operational simultaneously) Orbital location: 7 degrees East longitude Anticipated service life of 15 years Mission Profile: The Proton launch vehicle will inject the satellite into geosynchronous transfer orbit, using a five-burn Breeze M mission design. The first three stages of the Proton will use a standard ascent trajectory to place the Breeze M fourth stage, with the satellite, into a suborbital trajectory, from which the Breeze M will place itself and the spacecraft into a support orbit of 180 km (112 miles), inclined at 51.6 degrees. Then the satellite will be propelled to its transfer orbit by additional burns of the Breeze M. Following separation from the Breeze M, 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 miles). Target Orbit at Separation: Apogee: 35,786 km Perigee: 3,978 km Inclination: 13� Spacecraft Separation: Approximately 9 hours, 10 minutes after liftoff ILS Mission Statistics: 2nd ILS launch in a week 3rd ILS mission this year 1st Proton mission this year 28th ILS mission on Proton NEWS MEDIA ACTIVITIES Live Broadcast in U.S.: Galaxy 3 , transponder 2, C-band, 95 degrees West, downlink 3740 MHz (vertical), analog Test signals start at 5:30 p.m. EST In Europe & Russia: NSS-7, transponder NAV6/EUH6, Channel 1, Ku-band, 338 degrees East; FEC 3/4; downlink 11573.750 MHz (horizontal) Test signals start at 22:30 GMT More Information: Live webcast and general mission information are available on the ILS web site.
