The satellite's solar arrays deployed on schedule early this morning (July 1st), following yesterday's successful launch from the Baikonur Space Center in Kazakhstan aboard a Proton Breeze M launch vehicle provided by International Launch Services (ILS). The satellite is scheduled to begin firing its main thruster tomorrow in order to start maneuvering into geosynchronous orbit. SIRIUS FM-5 will be the highest-powered satellite in the SIRIUS fleet, with end-of-life power capability of nearly 20 kilowatts. It has a nine-meter unfurlable reflector, built by Harris Corporation, which allows for broadcast to cars and other small mobile devices. The satellite is based on SS/L's 1300 space-proven platform, which provides the flexibility to support a broad range of applications and technology advances. SIRIUS FM-5 will be the first geostationary satellite in the SIRIUS constellation, which already includes three SS/L built satellites in highly elliptical inclined orbits (HEIOs). The satellite will supplement the existing constellation in providing radio service to the continental U.S. as well as Canada. When SIRIUS FM-5 reaches its geostationary orbital slot at 96 degrees West, there will be 56 Space Systems/Loral GEO satellites on orbit.
