Sea Launch Delays Launch of XM Satellite

Sea Launch has delayed the
launch of XM Satellite Radio’s digital audio radio satellite
(XM “Roll”).
Yesterday’s launch countdown was halted when a minor
out-of-specification condition was detected on the satellite.
The Zenit-3SL
rocket performed as designed and the countdown was terminated in a successful
manner.

The out-of-specification condition was resolved within minutes of stopping
the launch.
The short launch window did not allow adequate time for a recycle
of the Sea Launch rocket.
Sea Launch is in the process of rescheduling the
launch.

Media representatives are encouraged to check the Sea Launch Media
Hotline, for the latest launch information.
