The four-hour window opens at 10:25 p.m. EDT (June 29, 0225 UTC, 04:25 CEST). If needed, a backup launch opportunity is available on Monday, June 29 during a four-hour window that opens at the same time. This will be the 17th flight for the Falcon 9 first stage booster supporting this mission, which previously launched Crew-9, RRT-1, Firefly Blue Ghost Mission 1, Fram2, SXM-10, MTG-S1, EchoStar XXV, and nine Starlink missions. After stage separation, the first stage will land on the A Shortfall of Gravitas droneship, which will be stationed in the Atlantic Ocean.

Positioned as part of SiriusXM’s third-generation fleet refresh, the spacecraft is scheduled for orbital deployment from Florida on a SpaceX Falcon 9 rocket. Design and Specifications: The satellite is built on the industry-proven 1300-class (IM-1300) platform, an architecture recognized for its long-term reliability in geostationary orbits. Reflector: It features a massive, unfurlable mesh reflector measuring nearly 10 meters (33 feet) in diameter, allowing robust signal penetration to moving vehicles. Solar Arrays: Upon deployment, the satellite's solar panel arrays span over 106 feet long, roughly the height of a 10-story building laid on its side. Mass: The heavy-class spacecraft weighs roughly 7,000 kilograms (15,432 lbs) at launch. Mission Purpose and Coverage: SiriusXM commissioned SXM-11 to enhance overall service quality, relieve strain on terrestrial network repeaters, and expand the company's active constellation. While many earlier satellites prioritized the contiguous United States, SXM-11 is designed with highly powerful antennas specifically tailored to expand coverage into Canada and southern Alaska. The satellite delivers over 250 channels of digital audio alongside specialized data. It feeds specialized marine and aviation cockpits with real-time weather information and supports the company’s hybrid 360L platform, which blends satellite broadcast with cellular streaming.
