SXM-7 is one of two upcoming satellites, the other being SXM-8 which is launching in early 2021, aiming to replace the XM-3 and XM-4 satellites.SXM-7 was built by Maxar Technologies and is based on their SSL-1300 satellite bus; a satellite bus is simply a set of core components that all satellites need (such as avionics, power, communication…) that customers can add to suit their needs. The satellite contains two large solar arrays and batteries for on-orbit storage. SXM-7 will operate in the S-band spectrum, between 2.32 GHz and 2.345 GHz. Each satellite has an operational lifetime of 15 years, after which the satellite is moved into a graveyard orbit.The Sirius XM satellite constellation was formed in 2008 when Sirius and XM merged into Sirius XM. The constellation provides satellite radio and online radio services to a significant portion of the world.The booster supporting this mission is B1051. This booster has flown six times. Its maiden flight was on SpaceX’s Demonstration Mission-1, which launched on March 2, 2019. Its second mission was launching the most expensive commercial payload launched, launching the RADARSAT constellation into orbit. Finally, the booster has been used on the V1.0 L3, V1.0 L6, V1.0 L8, and V1.0 L13 Starlink missions.This will be the 25th launch for SpaceX in 2020 and 102nd launch of a Falcon 9 rocket.
