SpaceX launched the SiriusXM SXM-11 satellite aboard a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station early Monday morning, June 29, 2026. Liftoff occurred at 2:25 AM UTC (10:25 p.m. ET on June 28), right at the opening of a four-hour launch window. The mission marks another step in SiriusXM's effort to refresh and expand its satellite constellation.
The Falcon 9 first stage booster, designated B1085, completed its 17th flight and successfully landed on the A Shortfall of Gravitas droneship in the Atlantic Ocean. B1085 has an impressive resume β prior missions include Crew-9, Firefly Blue Ghost Mission 1, Fram2, SXM-10, and nine Starlink runs. The SXM-11 satellite itself is no lightweight: tipping the scales at approximately 15,000 pounds, it was deployed into an elliptical geosynchronous transfer orbit roughly 34.5 minutes after liftoff.
Built by Lanteris Space Systems β formerly Maxar Space Systems, acquired by Intuitive Machines in January 2026 β on the proven IM-1300 platform, SXM-11 spans 106 feet tip-to-tip with solar panels deployed. The satellite is designed to enhance signal reception, extend coverage into Alaska, and eventually replace the aging XM-5 and Sirius FM-5 satellites currently serving listeners across the United States, Canada, and the Caribbean. With this launch, SpaceX's SpaceX coverage of commercial GTO missions continues at a steady clip heading into the second half of 2026.
