Astra 1M

Astra 1M is a Luxembourgian geostationary communications satellite which is operated by SES. It is positioned in geostationary orbit at a longitude of 19.2 degrees East, from where it is used to provide direct-to-home broadcasting to Europe.

Astra 1M was built by EADS Astrium under a contract signed in 2005, and is based around 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 ,[1] with an expected operational lifespan of around 15 years,[2] however four of its transponders will be deactivated five years after launch.[3] At the beginning of its operational life, it had a maximum power consumption of 9.3 kilowatts, which is expected to have decreased to 8.3 kilowatts by the end of the satellite's operational life.[1]

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