For those anxiously awaiting the news, XM Radio’s third satellite, XM-3, successfully reached orbit. Due to flaws in the solar panel design of XM-1 and XM-2 (Rock and Roll), XM-3 and XM-4 will need to be launched to eventually replace the early failing power of the first two. Rock and Roll will move to supplementing each other’s signals until XM-4 is launched potentially later this year, according to some reports.
