A Russian Proton-M launch vehicle carrying the Dutch SES-4 (NSS-14) telecoms satellite lifted off on Tuesday from the Baikonur Space Center in Kazakhstan after a series of delays caused by technical problems, Russia’s Federal Space Agency Roscosmos said.
“The launch occurred at the calculated time - 11:36 p.m. Moscow time [19:36 GMT],” Roscosmos said. “The separation of the satellite from the launch vehicle is expected at 08:48 a.m. Moscow time [04:48 GMT] on February 15.”
The blastoff was the 70th commercial launch of a Proton carrier rocket since 1995 under contracts concluded by International Launch Services Inc. (ILS).
ILS initially had to postpone the launch planned for December 26, 2011 after a problem affecting the avionics unit of the rocket’s Briz-M upper stage was discovered.
The launch was moved to a later date for the second time on January 28 due to an electrical problem affecting the Proton rocket.
The SES-4 is the largest and most powerful in the group of SES satellites, built by U.S. company Space Systems/Loral for the Dutch operator SES World Skies, which is now a subsidiary of Luxemburg-based SES S.A.
It was designed to provide various satellite services to customers in the Middle East, Europe, Africa and Latin America. Equipped with 52 C-band and 72 Ku-band transponders, the 5.8-ton satellite has a life span of 15 years.
The SES-4 will be deployed over the Atlantic Ocean region, enabling the incumbent NSS-7 satellite to move to a new orbital position.

During Vladimir Putin’s annual Q&A session some members of the Valdai International Discussion Club asked him several questions. How united is the West in its desire to punish Russia? Which EU countries are in favour of isolating Russia? Is this even possible? And what is going on in Ukraine?
