ST. LOUIS - Boeing today successfully launched NASA's Space
Infrared Telescope Facility, or SIRTF, aboard a Delta II Heavy launch
vehicle from Cape Canaveral Air Force Station, Fla.

Liftoff occurred on schedule at an instantaneous launch window of 1:35:39
a.m. EDT from Space Launch Complex 17B. Telemetry data indicated that the
launch vehicle successfully deployed SIRTF to a solar orbit.

SIRTF is the last of NASA's Great Observatories program, which includes the
Hubble Space Telescope, and the Chandra X-Ray and Compton Gamma Ray
Observatories. SIRTF will enable researchers from around the world to learn
more about the formation of the universe.

Today's launch for the Boeing Delta team commemorates 300 missions of a
Delta rocket, spanning over four decades of launching spacecraft for
government, commercial and civilian customers.

"Today's milestone launch reflects the efforts of thousands of dedicated
people who have worked so hard on Delta over the past four decades. Our team
has truly achieved an impressive accomplishment in Delta's history and the
launch industry. We thank our NASA customer for their continued confidence
in Delta to support important science missions such as SIRTF," said Jay
Witzling, vice president and deputy program manager, Boeing Delta programs.

The original Delta rocket, launched in 1960, later evolved into the Delta
II. Boeing then built the Delta III, which was used in part to help develop
the Delta IV.

The Delta II 7920 Heavy configuration uses nine stretched graphite epoxy
motors that provide 135,900 pounds of thrust at liftoff, increasing the
vehicle's lift performance up to 4,723 pounds (2,142 kilograms) to
geosynchronous transfer orbit. For the SIRTF mission, the Delta II Heavy
provided 31 percent more performance than the current Delta II.

The next Boeing Delta launch is the Defense Satellite Communications System
spacecraft, DSCS III B6 for the U.S. Air Force aboard a Delta IV Medium on
Aug. 28 from Cape Canaveral.
