Watch the launch here, in the video “SpaceX launches SiriusXM satellite aboard Falcon 9 rocket“, below:
SXM-7 is a high power broadcasting satellite. The Sirius XM satellite constellation currently consists of 5 satellites in geostationary orbit. 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. SpaceX is targeting Sunday, December 13 for the launch of the SXM-7 mission, which will launch from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station, Florida. The one-hour and 59-minute launch window opens at 11:22 a.m. EST, or 16:22 UTC, and a backup launch opportunity is available on Monday, December 14 with a one-hour and 59-minute launch window opening at 11:22 a.m. EST, or 16:22 UTC. The Falcon 9 first stage rocket booster supporting this launch previously supported Crew Dragon’s first flight to the International Space Station (Demo-1), launch of the RADARSAT Constellation Mission, and four Starlink launches in 2020. Following stage separation, SpaceX will land Falcon 9’s first stage on the “Just Read the Instructions” droneship, which will be located in the Atlantic Ocean. One half of Falcon 9’s fairing previously supported the ANASIS-II mission in July 2020. 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, in the video “SXM-7 FALCON 9 SpaceX launch, Live at Cape Canaveral Space Force Station, Florida, USA“, below:

Welcome to the latest SpaceX Starship updates video from TheSpaceXFans. Up first, we have a delay to the SXM-7 launch as well as Indonesia interested in hosting SpaceX launches. Then we will see a bunch of things in Boca Chica including SN8’s remains inspected, plus SpaceX are having SN9 problems. Sit back and enjoy, in the video “SpaceX Starship Updates!

To better understand Sirius XM, please refer to the excerpt from wikipedia, in italics, below:
Sirius XM Holdings Inc. is an American broadcasting company headquartered in Midtown Manhattan, New York City that provides satellite radio and online radio services operating in the United States. It was formed by the 2008 merger of Sirius Satellite Radio and XM Satellite Radio, merging them into SiriusXM Radio. The company also has a 70% equity interest in Sirius XM Canada,[1] anaffiliate company that provides Sirius and XM service in Canada. On 21 May 2013, Sirius XM Holdings, Inc. was incorporated,[1] and in November 2013, Sirius XM reorganized their corporate structure, which made Sirius XM Radio Inc. a direct, wholly owned subsidiary of Sirius XM Holdings, Inc.[2]The U.S. Federal Communications Commission (FCC) approved the merger of XM Satellite Radio and Sirius Satellite Radio, Inc. on 29 July 2008, 17 months after the companies first proposed it.[3] The merger created a company with 18.5 million subscribers,[3] and the deal was valued at US$3.3 billion, not including debt.[4] The proposed merger was opposed by those who felt it would create a monopoly. Sirius and XM argued that a merger was the only way that satellite radio could survive.[4]In September 2018, the company agreed to purchase the streaming music service Pandora,[5][6] and this transaction was completed on 1 February 2019.[7]As of 31 December 2019, Sirius XM had approximately 34.9 million subscribers.[1]Sirius XM Radio is a primary entry point for the Emergency Alert System.[8]

I am a mother/wife/daughter, math professor, solar advocate, world traveler, yogi, artist, photographer, sharer of knowledge/information, and resident of Windermere, FL. I've worked professionally in applied math, engineering, medical research, and as a university math professor in IL and FL for about 20 years. My husband and I loved Disney and moved down to Central Florida initially as snowbirds. But we've come to love the warmth and friendly people offered by this community and decided to move down to Windermere, FL full time in 2006. I am now spending time sharing information/ knowledge online, promoting understanding of math and solar energy (via http://www.sunisthefuture.net ), and developing Windermere Sun (http://www.WindermereSun.com) as an online publication, sharing and promoting Community ABC's (Activities-Businesses-Collaborations) for healthier/happier/more sustainable living. In the following posts, I'll be sharing with you some of the reasons why Windermere has attracted us to become full-time residents of Central Florida region.
