ARLINGTON, Va. — Iridium Satellite LLC announced today that it predicts
its constellation of satellites will retain mission functionality into
the next decade, based on internal analyses of satellite and operational
data, as well as an external study by an independent company.

Iridium contracted with The Aerospace Corporation of El Segundo, Calif.,
to conduct the study, based on several years of actual on-orbit
reliability data provided by Iridium. Incorporating assumptions of
planned future software and operational improvements, the analysis
indicated that the Iridium constellation would likely remain viable
into the next decade.

“Based on our observations and The Aerospace Corporation’s analysis,
we are confident that the Iridium satellite constellation will deliver
services to customers through mid-2010. The operational constellation
is performing beautifully, and with the 14 in-orbit and ground spares
we’ll continue providing quality service for years to come,” said Gino
Picasso, Iridium Satellite CEO. “Iridium continues to drive toward its
business plan objectives. Our solid financial backing, a growing
government and industrial customer base, the Department of Defense
contract and the anticipated life of the constellation communicate to
the marketplace that Iridium Satellite is poised for continued growth
and success.”

Dannie Stamp, Iridium Satellite Chief Operating Officer and former
director of Space Satellite Systems for the Iridium program said, “In
the past two years, the constellation has not required the use of any
in-orbit spare. Through a robust architecture and a highly-skilled
team of operators and engineers, the reliability of the Iridium
satellite constellation is far exceeding original design predictions.”

Comprised of 66 low-earth orbiting (LEO) satellites plus spares, the
Iridium Satellite constellation delivers global voice and data services
to industrial customers around the world who require communications
to and from remote locations. In 2002, Iridium Satellite will launch
additional spare satellites to ensure the system’s long-term
