The Sirius FM-5 satellite and its Russian Proton M rocket were delivered separately to the Baikonur Cosmodrome in Kazakhstan, according to International Launch Services (ILS).
After passing through customs, the spacecraft was transferred to building 92A-50 for testing and integration.
The satellite, built by Space Systems/Loral on the 1300 bus for Sirius XM Radio, is scheduled to be the fifth Proton launch this year and the third ILS mission of the year. Sirisu FM-5 will be inserted into a geostationary orbit and will supplement the existing fleet of SIRIUS satellites.
