SXM-8

SXM-8 and SXM-7 were contracted as a matched pair to replace SiriusXM's aging orbital assets - SXM-7 to succeed XM-3 and SXM-8 to succeed XM-4. After SXM-7 encountered payload failures during in-orbit testing following its December 2020 launch, SXM-8 carried more of the burden for the network's digital audio radio service.
