## FAQs
### Q: What is Sirius FM-5?
A: Sirius FM-5 is a geostationary communications satellite used for satellite radio, operated by Sirius XM and manufactured by Lanteris Space Systems.

### Q: When and how was Sirius FM-5 launched?
A: Sirius FM-5 was launched on 2009-06-30 from Baikonur Cosmodrome Site 200 aboard a Proton-M launch vehicle with a Briz-M upper stage.

### Q: What are the technical specifications and expected lifetime?
A: Sirius FM-5 had a launch mass of 5,840 kg, uses the Lanteris 1300 spacecraft bus, is powered by solar arrays plus R-4D and SPT-100 engines, and has a design/service life of 15 years.

## Why It Matters
Sirius FM-5 is a key asset in Sirius XM’s constellation of satellites that deliver satellite radio services. As a geostationary communications satellite with a 15-year design life, it contributes long-term capacity and continuity to the network that carries subscription radio and related services to listeners. Built on the Lanteris 1300 bus by Lanteris Space Systems and launched on a heavy-lift Proton-M with a Briz-M upper stage, the satellite represents a significant commercial space deployment involving international launch infrastructure. Its propulsion and power architecture — including solar arrays, R-4D, and SPT-100 thrusters — are characteristic of medium-to-large communications satellites designed for sustained station-keeping and operational reliability in geostationary orbit. For Sirius XM and its customers, satellites like FM-5 provide the backbone for nationwide satellite radio distribution independent of terrestrial networks.

## Notable For
- Launched on 2009-06-30 from Baikonur Cosmodrome Site 200 using a Proton-M/Briz-M stack.
