Sirius Satellite Radio Announces Successful Launch of Satellite


New York, NY - June 30, 2000 - Sirius Satellite Radio (Nasdaq: SIRI), the satellite radio broadcaster, today announced the successful launch of its first satellite, Sirius-1. Lift-off occurred on Friday, June 30 at 6:08 p.m. EDT. Sirius Satellite Control successfully established a communications link with Sirius-1 at 8:33 p.m. EDT and deployed the satellite's solar panels by approximately 11:55 p.m. EDT. Sirius-1 is the first satellite ever designed to deliver satellite radio broadcasts to the United States. Beginning at the end of this year, Sirius will deliver 50 channels of commercial-free music and up to 50 channels of news, sports and information seamlessly across the continental U.S. for a monthly subscription of $9.95. The other two satellites in Sirius' three-satellite constellation are scheduled to be launched and tested by November.

"Satellite radio is a reality," said Sirius chairman and chief executive, David Margolese. "The deployment of Sirius-1 means that within weeks we will be able to verify the fundamental capabilities of our system, including a coast-to-coast signal and digital-quality sound."

Sirius-1 was launched from the Baikonur Cosmodrome in Kazakhstan on a Proton/Block DM launch vehicle. "This mission was an unqualified success and ILS is proud to have launched the first Sirius satellite," said Dr. Mark J. Albrecht, President of International Launch Services (ILS). "We look forward to the next two launches, helping Sirius become the first digital satellite radio broadcaster in the United States."
