NEW YORK & PALO ALTO, CA — SiriusXM and Maxar Space Systems announced that the SXM-10 satellite has completed in-orbit testing and is now fully operational by SiriusXM following its successful launch by a SpaceX Falcon 9 rocket on June 7, 2025.
SiriusXM is the leading satellite radio service with 33 million subscribers.
“The SXM-10 satellite strengthens the health of our fleet and the infrastructure that provides a critical foundation for our audio entertainment and information services enjoyed by tens of millions of people across North America,” said Bridget Neville, SiriusXM’s Senior Vice President & GM of Signal Distribution Engineering.
“The successful launch and handover of SXM-10 marks another milestone in our long-standing partnership with SiriusXM,” said Chris Johnson, CEO of Maxar Space Systems. “This satellite reflects our shared commitment to innovation and reliability, and we are proud to be able to leverage our proven Maxar 1300™ platform to help SiriusXM deliver advanced audio entertainment services to millions of listeners.”
SXM-10 will help provide continuous reliable delivery of SiriusXM’s audio entertainment and information services to consumers. SXM-10 is the 11th high-powered, digital audio radio satellite built by Maxar Space Systems for SiriusXM and is built on the Maxar 1300™ platform. SXM-10 is more than 27 feet tall and over 100 feet long with its solar arrays deployed, and weighed almost 6,600 kg at launch. SXM-10 features a large unfurlable S-band reflector antenna supplied by L3Harris that enables SiriusXM programming to reach approximately 175 million SiriusXM-equipped vehicles on the road today.
SXM-10 is the second new satellite to commence service for SiriusXM in 2025 after SXM-9 began service in January. SiriusXM and Maxar Space Systems previously announced that Maxar Space has also been commissioned to build the SXM-11 and -12 satellites for SiriusXM, and those programs are ongoing with launches expected in 2026 and 2027, respectively.
