>     The "Clipper Graham" single-stage reusable rocket
>developed by NASA and McDonnell Douglas is scheduled to
>perform its fourth test flight at 3:30 p.m. EDT on Friday,
>July 12, at the U.S. Army White Sands Missile Range in New Mexico.
>     The 43-foot-high rocket will reach an altitude of 4,100
>feet and travel laterally 2,800 feet during its planned two-
>minute, 20-second flight.  During its flight the rocket will
>dip its nose 60 degrees toward the horizon, right itself and
>dip its nose 60 degrees in the opposite direction.  This
>flight maneuver will enable evaluation of the performance of
>new lightweight, high-strength materials and components.
>     The "Clipper Graham" has flown successfully three times.
>Its first flight was May 18, and its last two flights came
>just 26 hours apart on June 7 and 8.
>     The "Clipper Graham" was developed from the U.S. Air
>Force DC-X rocket which flew eight times between August 1993
>and July 1995.  The DC-X airframe was extensively modified by
>replacing existing systems with new technology components
>required for the development of a single-stage-to-orbit
>reusable launch vehicle.  These include a composite liquid
>hydrogen tank, the first ever to fly on a rocket, and a
>Russian-built aluminum-lithium alloy liquid oxygen tank.  The
>vehicle's advanced technology components all have performed
>well during its first three flights according to NASA program
>manager Dan Dumbacher of the Marshall Space Flight Center,
>Huntsville, AL.  The last flight planned for the vehicle will
>feature its first use of a new lightweight auxiliary power
>system which will convert liquid hydrogen to a gas for use in
>the vehicle's flight reaction control system and auxiliary
>power unit.  The reaction control system provides backup for
>the rocket's roll altitude during flight.
>     "Clipper Graham" is part of NASA's Reusable Launch
>Vehicle Technology program, together with the X-34 small
>technology demonstrator and the X-33 test vehicle which NASA
>and Lockheed-Martin are developing as a one-half scale model
>of the Reusable Launch Vehicle private industry likely will
>develop and operate during the first decade of the next century.
>     The Air Force's Phillips Laboratory at Kirtland Air
>Force Base, NM, is managing flight test operations.
>     While the "Clipper Graham" flight tests are not open to
>the general public, news media representatives may cover the
>tests by requesting accreditation from the White Sands
>Missile Range Public Affairs Office (facsimile machine number
>505/678-7174, phone 505/678-1134.  The point of contact is
>Debbie Bingham.  Even those media representatives already
>accredited must register in advance for each flight to ensure
>adequate transportation to the test site.  Media planning to
>view the test flight must be at Bldg. 122 by 11:30 a.m. on
>flight day, July 12.
