Johnson Space Center, Houston
EDITORS NOTE: N93-24
The STS-55 Spacelab D-2 postflight crew press conference will be held
Tuesday, May 19, at 11:00 a.m. EDT at the Johnson Space Center, Houston, in
building 2, room 135.
The crew members will narrate film highlights of their German research
mission to study life sciences and materials processing in microgravity. The
briefing will be carried on NASA Select television with two-way audio for
questions from NASA Headquarters and other centers. NASA Select programming is
carried on SATCOM F2R, transponder 13, located at 72 degrees west longitude.

5/10/93: WORLD'S LARGEST WIND TUNNEL WILL BE WORLD'S QUIETEST

RELEASE: 93-81
The world's largest wind tunnel soon will be the world's quietest,
thanks to a $25 million NASA sound insulation project.
NASA will design and install an acoustic lining in the 40-by-80-foot
test section of the National Full-scale Aerodynamics Complex (NFAC) at NASA's
Ames Research Center, Mountain View, Calif. The improved wind tunnel ultimately
will help U.S. industry design quieter engines for a future high-speed civil
transport and for new, advanced helicopters.
"It will provide the United States with a world-class capability that
will help us greatly during the next generation of aeronautical research," said
Ames Project Manager John Allmen. "After workers install the acoustic lining,
echoes will be greatly reduced. Microphones will be able to measure engine and
rotor sounds much more accurately with fewer sound waves bouncing off the
walls."
Background noise and echoes in the wind tunnel test section cause
problems for measuring sound during engine tests. The deeper the acoustic
liner, the lower the sound frequency engineers can measure accurately.
Construction workers will install a dense acoustic lining in the NFAC's
40- by-80-foot test section walls, floor and ceiling. The insulation material
comes in wedges 42 inches deep and about 4 feet square to cover that entire
area. The new lining is similar to the spun Fiberglas commonly used to
insulate houses.
Project design will take the next 2 years. Construction is scheduled
to begin in the spring of 1995. During construction, the test section will
shut down for more than a year.
Workers also will modify the wind tunnel's motor generators to let
engineers send more electric power to the main drive motors. "Normally, we
rotate the main drive motors at 180 rpm, but now we will be able to rotate them
at half that speed and cut the noise levels by 75 percent, " Allmen said. "This
major reduction in background noise will allow us to reach speeds of 100 knots
(105 mph) quietly."
Allmen noted that the tunnel's net operational costs will not rise
after the project is complete. "The modification costs are about one-twentieth
of the cost of building a new facility, which would cost more than $500
million," he said.

5/10/93: CONFERENCE COMMEMORATES SKYLAB, SPACELAB, SPACE STATION ANNIVERSARIES
Dave Drachlis, Mike Simmons
Marshall Space Flight Center May 7, 1993
Huntsville, Ala.
RELEASE NO: 93-46
The International Conference on Skylab, Spacelab, Space
Station, and Beyond will convene in Huntsville, Ala., May 13 in
the North Hall of the Von Braun Civic Center.
The day-long event will commemorate the 20th anniversary of
the launch of Skylab, the world's first space station; the 10th
anniversary of the first mission of Spacelab, a research
laboratory carried by the Space Shuttle; and the 10th anniversary
of Space Station concepts development.
The conference will bring together astronauts, scientists,
engineers and managers from around the world who participated in
these programs, and will serve as a platform for discussion of
future missions as space exploration continues to evolve from
expertise and knowledge gained from the programs.
At 8:15 a.m., Jack Lee, director of NASA's Marshall Space
Flight Center in Huntsville, will open the conference with
welcoming remarks. The Marshall Center was responsible for
development of Skylab, was the agency's lead organization for
development of the European Space Agency-provided Spacelab, and is
responsible for managing many of the Spacelab missions. The
center also has had a key role in Space Station development.
Seven of the nine Skylab astronauts are also scheduled to
participate in the conference. (Editors Note: The Skylab crew
members will be available to meet with reporters at 10 a.m., May
13, in the Rehearsal Hall, on the second floor over the VBCC
North, where they will talk about their experiences and answer
questions.)
A conference overview session at 8:30 a.m. will review
initiation and key challenges of each of the Skylab, Spacelab and
Space Station programs. Key government and contractor management
personnel who participated in the programs will give their views
on each programs goals and accomplishments.
A spacecraft systems seminar will address critical spacecraft
and transporation systems required to support human space
exploration capabilities. It will be held at 10:30 a.m.
A science session at 1:30 p.m. will review major science
accomplishments of Skylab and Spacelab and will highlight the
opportunities for future science investigations on Space Station.
And, beginning at 4:00 p.m., astronaut crew members from
Skylab and Spacelab will discuss from their personal experiences -
the spectrum of activities and accomplishments involved in those
programs.
Exhibits of space hardware and other memorabila from the
Skylab, Spacelab, and Space Station development programs will be
on display throughout the conference in the VBCC's East Exhibit
Hall.
A special Von Braun Exploration Seminar will cap the day's
activities with a presentation on the Challenges of Human Space
Flight at 8 p.m. at the U.S. Space and Rocket Center. This
session is open to the public free of charge, and the featured
speaker will be Skylab astronaut Joseph Kerwin.
