The final flight of NASA’s X-43A hypersonic research
aircraft has been rescheduled to occur no earlier than
Monday, Nov. 15, due to scheduling conflicts for use of the
U.S. Navy’s test range off the Southern California coast.

As a result, the X-43A pre-flight news media briefing at
NASA’s Dryden Flight Research Center, Edwards, Calif.,
originally scheduled for Nov. 5, will be held on Wednesday,
Nov. 10, at 1 p.m. EST. The briefing will be carried live on
NASA Television and webcast.

The X-43A, part of the Hyper-X hypersonic research program is
led by NASA’s Aeronautics Research Mission Directorate and
operated jointly by NASA’s Langley Research Center, Hampton,
Va., and Dryden. The program aims to demonstrate scramjet
air-breathing engine technologies that promise to increase
payload capacity, or reduce vehicle size for the same
payload, for future hypersonic aircraft and reusable space
launch vehicles.

Media representatives planning to attend the Nov. 10 briefing
must contact Dryden public affairs at: 661/276-3449 no later
than 7 p.m. EST (4 p.m. PST) Monday, Nov. 8. Those planning
to cover the flight itself and the post-flight news
conference should contact Dryden public affairs no later than
7 p.m. EST (4 p.m. PST) Wednesday, Nov. 10, for
accreditation. Reporters unable to attend in person may
submit questions to the panelists during the briefing via e-
mail at: x43nov@dfrc.nasa.gov or by phone at: 661/276-3449.
