Mission Details
SXM-9
SXM-9 is the 10th high-powered, digital, audio radio satellite built by Maxar (SSL) for SiriusXM. The SXM-9 satellite will be based on Maxar's proven 1300-class platform and built at the company's manufacturing facility in Palo Alto, California. It is expected that SXM-9 will launch in 2024. SXM-9 has a large, mesh, unfurlable reflector almost 10 meters in diameter that allows SiriusXM programming to reach its radios, including those in moving vehicles.

ЦитироватьSpaceX is targeting Thursday, December 5 for launch of the SiriusXM SXM-9 (https://sxcontent9668.azureedge.us/cms-assets/assets/SXM_9_ca68a00a13.png) mission to geosynchronous transfer orbit from Launch Complex 39A (LC-39A) at Kennedy Space Center in Florida. The 90-minute window opens at 11:10 a.m. ET. If needed, a backup launch opportunity is available on Friday, December 6 during a two-hour window that opens at the same time.

A live webcast of this mission will begin about 15 minutes prior to liftoff, which you can watch here and on X @SpaceX (https://twitter.com/SpaceX). You can also watch the webcast on the new X TV app.

This will be the 19th flight for the Falcon 9 first stage booster supporting this mission, which previously launched CRS-26, OneWeb Launch 16, Instelsat IS-40e, O3B mPOWER, Ovzon 3, Eutelsat 36D, Turksat 6A, Maxar 2, and 10 Starlink missions. After stage separation, the first stage will land on the Just Read the Instructions droneship, which will be stationed in the Atlantic Ocean...

Less than 30 minutes until Falcon 9's launch of the @SiriusXM SXM-9 mission from Florida. Propellant load is underway, and weather is looking good for liftoff

Encapsulated inside of the payload fairing for today's Falcon 9 launch in ~30 minutes, is SiriusXM's SXM-9 satellite. The ~7,000kg satellite was built by Maxar, and is a replacement for SXM-7, which failed in-orbit. It's also the 1st in a series to refresh SiriusXM's fleet.

Это он на своём апогйенике будет столько до ГСО вытягивать? Смотрится страшновато. Поискал - да, у SXM-8 было то же самое примерно. Что-то вроде ГПО-2200. Это сколько ж их этих 7 тонн приходится на горючку для апогейника, интересно.

"SiriusXM is committed to cutting-edge technology and enhancing the proprietary satellite delivery systems that help power our audio entertainment and information service offerings," said Bridget Neville, SiriusXM's Senior Vice President & GM of Signal Distribution Engineering. "The successful implementation of SXM-9 and expected launches of SXM-10, -11 and -12 will strengthen the health of our satellite fleet for decades to come and allow our team to continue innovating far into the future."

"At Maxar Space Systems, we take pride in partnering with innovative companies like SiriusXM that push the boundaries of what's possible," said Chris Johnson, CEO of Maxar Space Systems. "The Maxar 1300™ platform is designed with mission adaptability and reliability in mind, making it an ideal choice for the requirements of SXM-9 and the upcoming SXM-10, -11 and -12 satellites. Maxar remains committed to delivering high-quality solutions that allow our customers to innovate and achieve their long-term objectives."

SXM-9 will help provide continuous reliable delivery of SiriusXM's audio entertainment and information services to consumers in the United States, Canada and Puerto Rico. SXM-9 is the tenth high-powered, digital audio radio satellite built by Maxar Space Systems for SiriusXM and is built on the Maxar 1300™ platform. SXM-9 is more than 27 feet tall and over 100 feet long with its solar arrays deployed, and weighed almost 6,400 kg at launch. SXM-9 features a large unfurlable S-band reflector antenna supplied by L3Harris that enables SiriusXM programming to reach approximately 167 million SiriusXM-equipped vehicles on the road today.

SiriusXM and Maxar Space Systems previously announced that Maxar Space has been commissioned to build the SXM-10, -11 and -12 satellites for SiriusXM, and those programs are ongoing with the expected launch of SXM-10 to occur later this year.
