Mission

SXM-9 is the 10th high-powered, digital, audio radio satellite built by Maxar (SSL) for SiriusXM. The SXM-9 satellite will be based on Maxar’s proven 1300-class platform and built at the company’s manufacturing facility in Palo Alto, California. It is expected that SXM-9 will launch in 2024. SXM-9 has a large, mesh, unfurlable reflector almost 10 meters in diameter that allows SiriusXM programming to reach its radios, including those in moving vehicles.
