10:25 p.m. EDT liftoff from Cape Canaveral sent SiriusXM’s 15,000-pound SXM-11 into orbit, with the satellite deploying a little more than 30 minutes later.
SXM-11 is designed to replace SiriusXM’s aging XM-5 and Sirius FM-5 spacecraft and to improve signal reception while extending coverage in Alaska.
B1085 completed its 17th flight and landed on drone ship A Shortfall of Gravitas about 8.5 minutes after launch, marking the vessel’s 158th successful booster recovery.
Lanteris Space Systems—acquired by Intuitive Machines for about $800 million in January—built SXM-11 on the IM-1300 bus; SiriusXM says it is the most powerful satellite in its fleet.
The launch continues SiriusXM’s constellation refresh after SXM-10 flew in June 2025, with that satellite expected to remain in service until 2040.
