The Russian Satellite Communications Company lost contact with the $265-million Express AM-4 satellite shortly after launch aboard a Proton-M rocket from Kazakhstan.
The Express AM4, based on Astrium’s Eurostar E3000 satellite design, is the largest of the Express satellites so far. IT is equipped with a total of 63 active transponders in L-, C-, Ku- and Ka-bands and 10 antennas, both fixed and steerable. Its mission is to deliver digital TV, Internet and telecom services for eastern Russia. http://eng.rscc.ru/
