NEXT SPACE STATION COMPONENT TO LAUNCH BETWEEN JULY 8-14

                 Launch of the International Space Station's next
component
-- the Zvezda service module -- is scheduled to occur between July 8 and
14
from the Baikonur Cosmodrome in Kazakhstan, NASA and the Russian
Aviation
and Space Agency announced today. The Zvezda launch window will be
proposed
for approval to the International Space Station Partners in accordance
with
the ISS Control Board process within the next several weeks.

                 Following joint meetings in Moscow, including a General
Designer's Review and a Joint Program Review, Rosaviakosmos has proposed

that Zvezda (Russian for "Star") -- the early living quarters for crews
aboard the station - be launched on a Proton rocket with second and
third
stage engines modified to increase reliability.

                 The 42,000 pound Zvezda not only provides the early
living
quarters for astronauts and cosmonauts, but also the life support
system,
electrical power distribution, data processing system, flight control
system, and propulsion. While many of these systems will be supplemented
or
replaced by later U.S. station components, Zvezda always will remain the

structural and functional center of the Russian segment of the
International
Space Station.

                 Zvezda has a solar-array wingspan of 97.5 feet tip to
tip,
and is 43 feet long from end to end. The module contains three
pressurized
compartments and four docking ports.

                 Following Zvezda's launch and about 15 days of free
flight,
the ISS will rendezvous and dock with its newest module.

                 Launch of Zvezda sets the stage for the launch of other
ISS
components undergoing final testing at NASA's Kennedy Space Center in
Florida.

                 These components include a small truss segment that will

serve as the support structure for other station hardware; the first set
of
solar arrays; the United States Destiny laboratory; the Canadian-built
space
station robot arm; and several truss segments that will serve as the
station's backbone for external hardware, experiments and solar arrays.
Other key station components are also under development and testing in
Europe and Japan.
