TL;DR
SpaceX launched the SXM-11 satellite for SiriusXM using a Falcon 9 rocket, marking a key step in renewing SiriusXM’s satellite fleet. The satellite aims to improve signal coverage and service reliability.
SpaceX successfully launched the SXM-11 satellite for SiriusXM on June 28, 2026, at 10:25 p.m. EDT from Cape Canaveral. The 7.5-ton satellite was deployed into geostationary transfer orbit, marking a significant step in SiriusXM’s satellite fleet renewal.
The Falcon 9 rocket, with tail number B1085, lifted off from Space Launch Complex 40, carrying the SiriusXM SXM-11 satellite. The launch occurred within an 80-90% favorable weather window, according to the Weather Squadron. The rocket’s first stage successfully landed on the drone ship ‘A Shortfall of Gravitas’ in the Atlantic Ocean, marking its 158th landing.
The SXM-11 satellite, manufactured by Lanteris Space Systems, a subsidiary of Intuitive Machines, weighs approximately 15,000 pounds (7.5 tons) and is based on the IM-1300 satellite bus. It is designed to replace SiriusXM’s SXM-5 and Sirius FM-5 satellites, launched in 2010 and 2009, respectively. SiriusXM stated the satellite will enhance signal reception, expand coverage in Alaska, and support services across the U.S., Canada, and the Caribbean.
According to SiriusXM, SXM-11 is the most powerful high-powered satellite in the company’s fleet, with about 60% of its mass from onboard fuel. The satellite’s operational lifespan is expected to extend until around 2040, based on prior satellite performance and SiriusXM disclosures.
Implications for Satellite Communications and Coverage
The launch of SXM-11 represents a major upgrade for SiriusXM’s satellite fleet, aimed at improving signal strength, coverage, and reliability across North America and the Caribbean. This renewal helps SiriusXM maintain its competitive edge in satellite radio and audio entertainment services amid increasing demand and technological advancements.
Additionally, the deployment of a high-power, modern satellite supports SiriusXM’s long-term service plans, including expanding coverage in remote regions such as Alaska. It also demonstrates SpaceX’s continued success in launching large, complex payloads for commercial clients, reinforcing its role in satellite deployment for communications infrastructure.
