Russia`s Proton-M heavy carrier rocket put a U.S. Sirius XM-5 satelliteintoorbit on Friday, a spokesman for Russia`s space agency, Roskosmos, said.
"The Russian part of the program is complete: the [U.S.] spacecraft separated from the Briz-M upper stage rocket 9 hours and 12 minutes after the blastoff," the spokesman said.
The Proton-M blasted off from the Baikonur Space Center in Kazakhstan at 22:53 Moscow time [18:53 GMT] on Thursday.
A contract to launch the Sirius XM-5 was concluded between the Russian-U.S. joint venture International Launch Services (ILS) and the Sirius XM Radio, Inc.
Sirius XM-5, a powerful geostationary satellite built by Space Systems/Loral, will function as an in-orbit backup for the Sirius XM satellite radio network. All four previous Sirius satellites were launched on Proton rockets.
