Mission overview

On February 28, SpaceX will conduct the SXM‑11 mission, placing the latest SiriusXM satellite into orbit aboard a Falcon 9. The launch is part of a broader effort to refresh the company’s communications constellation.

Satellite specifications

Built by Intuitive Machines, the spacecraft stands over 70 feet tall and has a mass of approximately 7.5 tonnes. It will serve as a critical node in SiriusXM’s network, delivering radio and data services across a wide geographic area.

Launch site and window

The vehicle will lift off from Launch Pad 40 at Cape Canaveral Space Force Station in Florida. The launch window opens at 10:25 p.m. Eastern Daylight Time (02:25 UTC), providing a brief period for final countdown procedures.

Falcon 9 technical details

The Falcon 9 features a reusable first stage that returns to Earth for a controlled landing after stage separation. This reusability lowers launch costs and aligns with SpaceX’s goal of making space access more affordable.

Industry implications

This launch underscores the ongoing trend toward modular, reusable satellite systems as operators modernize their constellations. The new satellite is expected to enhance SiriusXM’s service coverage and improve overall network reliability.
