SpaceX Delivers SiriusXM’s 7.5‑Ton SXM‑11 to Geosynchronous Transfer Orbit

SiriusXM will deploy SXM‑11 to replace aging satellites, improving signal reach and coverage in Alaska.

Overview

  • The Falcon 9 launched SXM‑11 from Cape Canaveral and deployed the roughly 15,000‑ to 15,400‑pound satellite to a geosynchronous transfer orbit during the June 28–29 launch window.
  • First‑stage booster B1085 completed its 17th flight and landed on the droneship A Shortfall of Gravitas about 8½ minutes after liftoff, underscoring SpaceX’s routine reuse of flight‑proven boosters.
  • SXM‑11 was built on the IM‑1300 bus by Lanteris Space Systems, now a subsidiary of Intuitive Machines following its January 2026 acquisition of the former Maxar business.
  • SiriusXM says the spacecraft is the most powerful in its fleet, holds about 60% of its ~7.5‑ton mass as propellant for transfer and station‑keeping, and will move from GTO to its geostationary slot to replace XM‑5 and Sirius FM‑5.
  • The new satellite is part of a multi‑satellite fleet refresh intended to boost signal reliability for U.S., Canadian and Caribbean subscribers and extend service in Alaska, and the launch reinforces demand for high‑cadence reusable launch services.
