Moscow : Russia s Proton-M carrier rocket failed to put into orbit two telecommunications satellites due to problems in its booster stage, federal space agency Roscosmos said Tuesday.
Russia Monday night launched Telkom 3 and Express MD2 aboard the Proton-M from the Baikonur cosmodrome in Kazakhstan, Xinhua reported. However, "the Briz-M booster and the two satellites have not been detected on the transition orbit.
The signal from the booster has been received from an interim emergency orbit", the agency said in a statement.
Preliminary information showed the Briz-M only had fired for seven seconds rather than the scheduled 18 minutes and 5 seconds. Due to the failure, all launches of the Proton-M rocket were temporarily suspended pending the end of investigations.
Russia launches two telecom satellites
Moscow : Russia launched two telecommunications satellites Monday night aboard a Proton-M rocket from the Baikonur space centre in Kazakhstan, according to the Russian Federal Space Agency Roscosmos.
Live webcast from Roscosmos showed that the Proton carrier rocket blasted off from the Cosmodrome at 11.31 p.m. as scheduled, Xinhua reported.
The Indonesian satellite -- Telkom 3 -- is scheduled to separate from the rocket s upper stage at 8.44 a.m. Tuesday and the Russian satellite -- Express MD2 -- at 9.14 a.m., said Roscosmos.
The 1.8-tonne Telkom 3, with a life span of 15 years, is developed by the Information Satellite Systems-Reshetnev Company of Russia.
It will provide broadcasting and communications services for Indonesia, and is expected to improve the country s IT infrastructure. Express MD2, with a life span of 10 years, was designed and developed jointly by Russia and France.
It will provide broadcasting, communications, internet and other services for Russia s Far East and Southern Siberia regions. Monday s launch was the sixth of the Proton rocket in 2012, and the 378th in its flight history.
