Satellite descriptionEdit

Astra 1M was built by Astrium (now Airbus Defence and Space) under a contract signed in July 2005, and is based on the Eurostar 3000S satellite bus. It is equipped with thirty six transponders operating in the J-band of the NATO-defined spectrum, or the Ku-band of the older IEEE-defined spectrum. At launch it had a mass of 5,320 kg (11,730 lb),[1] with an expected operational lifespan of 15 years,[2] however four of its transponders were deactivated five years after launch.[3] At the beginning of its operational life, it had a maximum power consumption of 10 kilowatts by the end of the satellite's operational life.[3]


The launch of Astra 1M was conducted by International Launch Services (ILS), using a Proton-M launch vehicle with a Briz-M upper stage. The launch occurred from Site 200/39 at the Baikonur Cosmodrome in Kazakhstan, at 20:44:20 UTC on 5 November 2008.[4] Astra 1M was successfully placed into a geostationary transfer orbit (GTO), from which it raised itself to geostationary orbit by means of an onboard apogee motor.
