Summary
XM-2 (ROCK), also known as XM Radio-2, is a communication satellite launched on March 18, 2001, from the Sea Launch platform using a Zenit-3SL launch vehicle. It was manufactured by BOES and has a configuration of BSS-702 with dimensions of 7 meters in length, 3.3 meters in diameter, and a span of 40.4 meters due to its solar arrays. The satellite has a dry mass of 2500 kg and a launch mass of 4682 kg. Equipped with 13.3 kW digital audio radio capacity and two active S-band transponders each with 16 active (and 6 spare) TWTAs at 228 W, it provides communication services for XM Radio. Its power system includes two deployable solar arrays and batteries. The satellite's shape is described as a box with two panels, and its operational lifetime was projected to be 15 years.
