XM-2 (Rock)

 2001-012A


Two HS-702 DARS satellites, XM-Rock and XM-Roll, were ordered from Hughes in 1998 by AMRC (American Mobile Radio Corp), later XM Radio, for delivery on orbit by Delta 3 in Apr and Aug 2000, carrying Alcatel digital radio S-band payloads.

XM Radio seems to be part of Motient. The satellite was retired in 2014.
