RELEASE: 93-52
NASA's Langley Research Center, Hampton, Va., will lead a multi-year,
research program effort to develop technology for a future high-speed civil
transport.
The joint NASA-industry effort would provide a technical foundation
that the nation's aerospace companies could use to make intelligent business
decisions about future supersonic transport airframe and engine development
programs.
"The program is laying a technical foundation for an environmentally
compatible, economically practical commercial transport that could contribute
up to 140,000 jobs and $200 billion to the national economy in the next
century," said Louis J. Williams, Director of the High-Speed Research Division,
NASA Headquarters, Washington, D.C.
Langley will manage high-speed technology in aerodynamic performance,
airframe materials and structures, flight deck systems and airframe and systems
integration. And, Langley researchers are working to reduce sonic boom, reduce
overall structural weight and improve aerodynamic performance.
NASA's Lewis Research Center, Cleveland, is working on technology that
will reduce engine noise and dramatically lower nitrogen oxide emissions that
might affect Earth's ozone layer.
NASA's Ames Research Center, Mountain View, Calif., is flying high-
altitude missions to analyze the impact of a future high-speed civil
transport's engine exhaust on the atmosphere.
NASA's Dryden Flight Research Facility Edwards, Calif., is
flight-testing a drag-reduction concept called "laminar flow control" that
could significantly improve the efficiency of a supersonic transport's wings.
The High-Speed Research Program will complete Phase I, focused on
environmental challenges, in 1996. Phase II, which began in 1993, focuses on
technology to provide economic viability for a high-speed civil transport.
The program's technical management is being consolidated at Langley
because the center has research skills and facilities in most of the
disciplines important to the success of a future high-speed airliner. W. Ray
Hook has been named to head the project office.
"Hook's previous program management experience, coupled with his
involvement in the Atmospheric Science Division's analysis of the potential
environmental impact of a high-speed transport and his unique experience as the
leader of the NASA Aeronautics Red Team, make him especially well qualified for
this important leadership position," said H. Lee Beach, Acting Langley
Director.

Today at 1:00 p.m. EST NASA TV will replay the Pioneer/Venus Orbiter Final
Report Press Conference which was held at the Ames Research Center,
Calif.,yesterday.
The Pioneer Venus Orbiter spacecraft's last findings provided new evidence that
the planet Venus once had three and a half times more water than previously
thought. This is enough water to cover the entire surface between 25 and 75
feet deep.
The new data provided by the Pioneer Venus orbiter spacecraft shows that at the
spacecraft's lowest altitude, 80 miles 'whistler' radio signals were detected
and are believed to be generated by the Venus' lightning. These "whistler'
radio signals were the strongest ever detected and are the same as the radio
signals used in most lightning studies on Earth.
Pioneer's exploring came to an end on Oct. 8, 1992, after it entered Venus'
atmosphere and burned up. This ended 14 years of exploration

3/25/93: LAUNCH ADVISORY: STS-56 FLIGHT READINESS REVIEW COMPLETED
Jim Cast
Headquarters, Washington, D.C. March 25, 1993
George Diller
Kennedy Space Center, Fla.
The Flight Readiness Review for the launch of STS- 56/Discovery was
held today with no major issues identified.
Shuttle managers will set a target launch date next week after
resolution of the problem which caused last's Monday's engine shutdown on Space
Shuttle Columbia.
The primary STS-56 payload, ATLAS 2, will investigate the sun's energy
output and the Earth's middle-atmosphere chemical makeup and how these factors
affect levels of Earth's ozone, which prevents much of the sun's harmful
ultraviolet radiation from reaching the Earth's surface.
The 8-day STS-56 mission will be commanded by Kenneth Cameron and
piloted by Steven Oswald. Three mission specialists will round out the
five-person crew: Michael Foale, Kenneth Cockrell and Ellen Ochoa.

STS-55 LAUNCH DELAY
SPACELINK NOTE: We'll post additional information on the launch as
it becomes available. Previously issued news releases and status reports
concerning the STS-55 launch follow.
3/22/93
While igniting Columbia's three main engines which began at
T-6.6 seconds, the onboard computers initiated a main engine abort
sequence. Shutdown was completed at approximately T-3 seconds at
9:51 a.m. EST.
The reason for the abort appears to be that main engine #3
did not fully ignite due to a liquid oxygen preburner check valve
which apparently experienced an internal leak, causing the purge
system to be pressurized above the maximum 50 pounds per square
inch allowed. Ambient pressure would have allowed full engine
ignition to occur. The onboard computers sensed the higher than
allowed pressure in the line and terminated the main engine
ignition sequence.
The amount of time estimated to pick up the Columbia's STS-55 countdown again
is about a minimum of three weeks. No definite schedule has been developed.
Schedule options are under consideration this week.

Release No. 22-93
NOTE TO EDITORS: NEW LAUNCH DATE FOR STS-55 MISSION
NASA Managers today set March 21, 1993 as the launch date for Shuttle
Mission STS-55 which will see Space Shuttle Columbia and her 7 member crew fly
a mission dedicated to the German Space Agency. The major payload for STS-55,
the pressurized spacelab module - designated as Spacelab-D2 for this flight -
will allow the astronauts to conduct a wide range of experiments in the
microgravity environment of space.
The launch window on March 21 opens at 9:52 a.m. EST. Following launch,
Columbia's crew will be divided into two teams each working a 12-hour shift, so
that science operations can be carried out around the clock. The Spacelab-D2
mission duration is planned for 9 days and will conclude with a landing at
Kennedy Space Center's Shuttle Landing Facility.
Columbia's launch date will have an influence on the next mission to be
flown. Space shuttle Discovery, flying the ATLAS 2 payload on Shuttle Mission
STS-56, now targeted for launch sometime around April 7th. The actual launch
date for STS-56 will be set at a Flight Readiness Review meeting which will be
held approximately two weeks before launch.
"The Shuttle team has done a great job in addressing and closing issues
such as the hydraulic flex hose problem and putting together a new plan for
processing activities" said Shuttle Director Tom Utsman. "Also the cooperation
we've received from the United States Navy, the United States Air Force and
Hughes Space and Communication Company made the March 21st launch of Columbia
possible."
STS-55 STATUS 3/08/93
DAILY NEWS/TV SKED
Daily News
Monday, March 8, 1993
Managers and engineers will continue to asses the launch schedule impact
attributable to inspections of the hydraulic flex hoses and clean-up and
inspection of the aft engine compartment and number two main engine. An
assessment of a new schedule will be made available early this week.
2/26/93: MARCH 14 SET AS LAUNCH DATE FOR STS-55 MISSION

KSC Release No. 16 - 93
NASA managers today set March 14, 1993 as the launch date
for Shuttle Mission STS-55 which will see Space Shuttle Columbia
and her seven-member crew fly a mission dedicated to the German
Space Agency.
The major payload for STS-55, the pressurized spacelab
module - designated as Spacelab-D2 for this flight - will allow
the astronauts to conduct a wide range of experiments in the
microgravity environment of space. Some 90 experiments are
planned during the mission.
The launch announcement follows the removal, inspection and
replacement of the high pressure oxidizer turbopumps on
Columbia's three main engines. The pump changeout came after a
search of processing paperwork could not conclusively determine
that the pumps were equipped with a newer version of turbine tip
seal retainers. The seals minimize the flow of gas around the
tips of the turbine blades to enhance pump performance and the
retainers hold the seals in place.
The launch window on March 14 extends from 10 a.m. until
12:30 p.m. EST. Following launch, Columbia's crew will be
divided into two teams, each working a 12-hour shift, so that
science operations can be carried out around the clock. The
Spacelab-D2 mission duration is planned for 9 days and will con-
clude with a landing at Kennedy Space Center's Shuttle Landing
Facility. This date was chosen primarily because it was the
first open date on the Eastern Range during this time frame.

STS-55 REVIEW COMPLETED, LAUNCH DATE TO BE SET LATER

Kennedy Space Center, Fla.
NOTE TO EDITORS: N93-7
NASA managers today completed their review of the flight readiness of
Shuttle Mission STS-55, a mission dedicated primarily to the German Space
Agency for research in life and microgravity sciences.
Because of a decision reached yesterday to remove and replace
Columbia's high pressure oxidizer pumps, a launch date for the mission was not
set. Managers are still assessing the time it will take to perform the work
and resume launch preparations. Tom Utsman, Director of the Space Shuttle
Program, said a launch date for STS-55 would be set the last week in February.
The pumps being replaced feed super cold oxygen to the Shuttle's three
main engines. They are being removed because a search of processing paperwork
could not conclusively determine that the pumps are equipped with a newer
version of turbine tip seal retainers. The tip seals minimize the flow of gas
around the tips of the turbine blades to enhance pump performance and the
retainers hold the seals in place.
The major payload for Space Shuttle Columbia and her 7 member crew is
the pressurized Spacelab module - designated Spacelab-D2 - which will allow the
astronauts to conduct a wide range of experiments in the microgravity
environment of space. Some 90 experiments are planned during the mission.
This will be the 14th flight of the orbiter Columbia and the 54th Space
Shuttle mission.
