Note to Editors/News Directors:

The launch of NASA’s Tracking and Data Relay Satellite-H (TDRS-H)
aboard a Lockheed Martin Atlas IIA rocket (AC-139) is scheduled for
Thursday, June 29. Liftoff is targeted to occur at the opening of a launch
window that extends from 8:38 – 9:18 a.m. EDT, a duration of 40 minutes.
Launch will occur from Pad A at Complex 36 on Cape Canaveral Air Force
Station.

TDRS-H is the first in a new series of three Tracking and
Data Relay Satellites designed to replenish the existing on-orbit fleet of
six spacecraft, the first of which was launched in 1983. It is also the
first TDRS spacecraft designed to be launched on an expendable vehicle
instead of the Space Shuttle. The Tracking and Data Relay Satellite System
is the primary source of air-to-ground voice, data and telemetry for the
Space Shuttle. It also provides the communications and data capability for
the International Space Station and scientific spacecraft in low earth orbit
such as the Hubble Space Telescope and the Chandra X-ray Observatory. This
new advanced series of satellites will extend the availability of TDRS
communications services until approximately 2010.

TDRS-H Prelaunch Press Conference

The prelaunch press conference will be held at the NASA-KSC News
Center on Wednesday, June 28, at 10 a.m. EDT. Participating in the briefing
will be:

* Robert Spearing, NASA Deputy Associate Administrator for Space
Communications

* Stan Newberry, Director, Space Operations Management Office, Johnson
Space Center

* Randy Brinkley, Senior Program Vice President, Hughes Space and
Communications

* Chuck Dovale, NASA Launch Manager, Kennedy Space Center
