    19.2 Doğu yörüngesine konumlandırılacak olan ve tahmini 15 yıl hizmet vermesi öngörülen Astra 1M uydusu için geri sayım sürüyor.

    Eğer bir aksilik olmazsa bu gece saat ( T.S. ) 22:44 gibi fırlatma gerçekleşecek.

    Bu uydunun yılbaşından sonra ( fırlatılışından itibaren 3-6 ay arası ) aktif olması beklenmektedir.

    Bizdekiler gibi acele ederek sonradan karşılaşılan sorunları çözmek yerine burada izlenilen yol uyduda tüm denemeleri gerçekleştirdikten sonra faaliyete geçirmek, sorun yaşanmasının önüne geçmektir ve bu da belli bir zaman alacaktır.


    ILS PROTON TO LAUNCH ASTRA 1M

    Oct. 30, 2008
    Payload:
    ASTRA 1M communications satellite
    Eurostar E3000 bus
    Separated spacecraft mass: Approx. 11,729 lbs (5,320 kg)
    Launch Vehicle:
    Proton M/Breeze M
    702,000 kg (1,547,000 lbs), including payload
    58.2 m (191 ft)
    Launch Date:
    Nov. 6 (Baikonur)
    Nov. 5 (GMT, North America)
    Launch Time:
    02:44 Baikonur
    20:44 GMT
    15:44 EST
    Launch Site:
    Baikonur Cosmodrome, Kazakhstan
    Launch Pad 39
    Launch Customer:
    SES ASTRA, Luxembourg
    Satellite Manufacturer:
    EADS Astrium, France
    Launch Vehicle Manufacturer:
    Khrunichev State Research and Production Space Center,Moscow
    Launch Services Provider:
    International Launch Services, Reston, Va.
    Satellite Use:
    ASTRA 1M will be positioned at 19.2 degrees East longitude, where it will provide pan-European coverage. It will primarily deliver direct-to-home services, including high-definition television. The launch of the spacecraft will allow SES ASTRA to move capacity to its increasingly important orbital position 23.5 degrees East. ASTRA 1M will carry 36 transponders covering the FSS and BSS frequency bands.
    Satellite Statistics:
    Solar array span of 35 meters
    Spacecraft power of 10kw
    Orbital location: 19.2 degrees East longitude
    Anticipated service life: 15 years
    Mission Profile:
    The Proton M launch vehicle, utilizing a 5-burn Breeze M mission design, will lift off from Pad 39 at Baikonur Cosmodrome, Kazakhstan, with the ASTRA 1M satellite on board. The first three stages of the Proton will use a standard ascent profile to place the orbital unit (Breeze M upper stage and the ASTRA 1M satellite) into a sub-orbital trajectory. From this point in the mission, the Breeze M will perform planned mission maneuvers to advance the orbital unit first to a circular parking orbit, then to an intermediate orbit, followed by a transfer orbit and finally to a geosynchronous transfer orbit. Separation of the ASTRA 1M satellite is scheduled to occur approximately 9 hours, 12 minutes into the mission.
    Target Orbit at Separation:
    Apogee: 35,786 km (22,236 miles)
    Perigee: 4,980 km (3,094 miles)
    Inclination: 21.5 degrees
    Spacecraft Separation:
    Approximately 9 hours, 12 minutes after liftoff
    ILS Mission Statistics:
    5th ILS launch of 2008
    48th Proton launch for ILS
    11th Eurostar satellite launched on a Proton
