RELEASE: 93-127
NASA and the Federal Aviation Administration (FAA) will co- host a
briefing July 19-20 for aviation industry representatives about a
NASA-developed automated air traffic control tool that could save airlines
hundreds of millions of dollars.
The Center/TRACON Automation System (CTAS) helps air traffic controllers
schedule arriving aircraft more effectively, starting when planes are still
about 200 miles from an airport. The briefing at NASA's Ames Research Center,
Mountain View, Calif., will describe how CTAS works, review NASA's research to
date and discuss the FAA's plans to deploy the system.
The FAA predicts that bringing CTAS on-line at just 12 selected airports
will save airlines nearly $600 million in operating costs and reduced delays by
the year 2000.
"CTAS is a prime example of how the combined strength of research,
operations and manufacturing organizations, leveraged together, will help the
United States prevail in the global marketplace," said Wesley L. Harris, NASA's
Associate Administrator for Aeronautics.
The FAA's Associate Administrator for System Engineering & Development,
Marty Pozesky, describes CTAS as "a joint FAA/NASA research and development
effort to enhance flight efficiency by incorporating new air traffic control
automation into the existing system."
"We have designed CTAS tools to bridge the gap between controllers and
pilots, thereby improving the efficiency of the air traffic system as a whole,"
said Dr. Heinz Erzberger, Chief CTAS Designer.
Inefficient, inconsistent spacing between aircraft creates delays in
airport arrivals. The FAA has regulations that govern the spacing of arrivals
at each of the nation's airports, but air traffic controllers normally add a
"buffer" to that distance based on their individual experience and judgment.
CTAS helps controllers to more accurately space the aircraft by monitoring
aircraft during the last 20 minutes of flight and presenting information on
displays that pop up on the screen controllers normally use. The system has
three highly integrated, automated parts:
-- Traffic Management Advisor looks at planes as they come in from all
directions while they are still about 200-300 miles from the airport. As the
aircraft approaches, it develops a plan to handle the traffic effectively
according to the spacing requirements for that airport.
-- Descent Advisor generates graphic displays of space and time
relationships among incoming planes as they converge on an aerial "gate" about
40 miles out and provides controllers with accurate, fuel-efficient descent and
vectoring advisories.
-- Final Approach Spacing Tool lets controllers make corrections to the
spacing between aircraft after they have flown through the gate and are within
40 miles of the airport.
NASA began to research the air traffic control process in the late 1970s.
The advent of graphics-oriented computers in the 1980s provides the means for
taking these research ideas from the laboratory to the field.
Since May 1992, NASA and the FAA have been testing CTAS at Stapleton
International Airport, Denver, and the air route traffic control center in
Longmont, Colo. The simpler parts of the system are used in operations while
the more complex parts work in "shadow" mode, where real radar data drives CTAS
and the system provides advisories, but controllers do not act on them. NASA
personnel are located in the facility and get real-time feedback from
participating controllers.
Similar CTAS operations are slated to begin soon at Dallas/Fort Worth
International Airport. NASA researchers believe that area will be an excellent
test of the system because there is heavy traffic and the airport is surrounded
by many satellite airfields.
The limited deployment of CTAS is a multi-million-dollar part of the FAA's
Terminal Automation program, a new air traffic control system that will be in
place by the end of this decade.

KSC SHUTTLE STATUS REPORT 7/15/93
KENNEDY SPACE CENTER SPACE SHUTTLE STATUS REPORT
Thursday, July 15, 1993
KSC Contact: Bruce Buckingham
MISSION: STS-51 ACTS-TOS/ORFEUS-SPAS
Launch minus 2 days
VEHICLE: Discovery/OV-103 ORBITAL ALTITUDE: 184 miles
LOCATION: Pad 39-B INCLINATION: 28.45 degrees
LAUNCH DATE: Saturday, July 17, 1993 CREW SIZE: 5
LAUNCH WINDOW: 9:22 - 10:24 a.m. EDT
EXPECTED KSC LANDING DATE/TIME: July 26 or 27 7:21 a.m. EDT
EXPECTED MISSION DURATION: 8 days/22 hours + 1 day (an additional
day on orbit may be granted if orbiter cryogenics allow)
The countdown for Discovery's launch continues without problem at KSC's
pad 39-B. No technical or hardware issues are being worked. The primary
operation at the pad today features the loading of the onboard cryogenic tanks
with the liquid oxygen and liquid hydrogen reactants. These reactants provide
the orbiter's electricity while in space and a by-product of drinking water.
The pad was closed to all non-essential personnel at about 9:30 a.m. today for
this operation. Cryogenic flow is expected to begin at about 11:30 a.m. and
continue for about 5 hours. Follow- ing this operation the orbiter mid-body
umbilical unit will be demated. Communications activation and final vehicle
and facility closeouts will begin. Also preparations will be made to retract
the rotating service structure to launch position at about 11:00 a.m. tomorrow.
Forecasters continue to indicate a 10 percent probability of weather
prohibiting launch with a slight chance of showers being the primary concern.
The winds at the pad are expected to be from the southwest at 4 to 6 knots;
temperature 84 degrees F.; visibility 7 miles; and clouds scattered at 3,000
and 25,000 feet. A 24-hour or 48-hour delay will see about the same condi-
tions with a forecast 20 percent chance of violation.
The five-member astronaut crew for this mission arrived at KSC's Shuttle
Landing Facility at about 3:30 p.m. yesterday. Today they will be involved
with checking out their mission plans and fit checks of their equipment. They
are scheduled for some free time this afternoon and will be ready for sleep at
about 6:30 p.m. They will be awakened tomorrow at about 2:30 a.m.

After more than 450 orbits of aerobraking, the Magellan spacecraft continues to
successfully circularize its orbit around Venus. This week, Magellan is passing
through a phase in which the local gravity field changes. This phase is
causing the spacecraft, at its closest point to the planet, to drift upward
instead of toward the planet.
To keep the orbit change on course for achieving a 102- minute orbit by July
27, project officials plan to perform a maneuver today. The "end game" will
begin to place Magellan in the desired orbit for collecting gravity data in the
higher latitudes of Venus. Magellan's systems remain in normal with

7/15/93: NASA OSHKOSH EXHIBIT HIGHLIGHTS U.S.-LEADERSHIP IN AERONAUTICS
Barbara Selby
Headquarters, Washington, D.C. July 15, 1993
RELEASE: 93-128
NASA returns to the annual Experimental Aircraft Association Fly-In
Convention And Sport Aviation Exhibition at Oshkosh, Wisc., July 29-Aug. 6,
with a different look to NASA's exhibit and a special focus on general aviation
technology.
The modular "NASA and American Leadership in Aeronautics" exhibit explains
how NASA is addressing the challenges of aircraft in every speed regime, in
every size from tiny homebuilts to giant airliners. The exhibit also stresses
how NASA's Rcustomers' in government, industry, universities -- and ultimately,
the American taxpayer -- benefit from the agency's advances in aeronautics.
In front of the NASA pavilion, visitors may examine the world's first
lightning-protected, composite kit-built aircraft, the Glasair III LP.
Stoddard- Hamilton Aircraft, Inc., developed the plane under a
highly-successful NASA effort to increase the role of small business in federal
high-technology research.
Inside the exhibit hall, "High Speed for World Travelers" shows what NASA
is doing to make a next-generation supersonic airliner possible. Colorful
photos and graphics explain how the agency is tackling the three environmental
issues - exhaust emissions, airport noise and sonic boom - that, if solved,
will make it easier for U.S. industry to design and build such an aircraft.
Highlights of the display are a striking 10-foot model of a future
high-speed civil transport concept and an actual "mixer-ejector" nozzle design.
Advanced noise suppressors like the nozzle could reduce takeoff and landing
loudness of a future supersonic airliner to one-quarter that of today's
Concorde.
"Toward Safer Skies" showcases NASA's role in making air travel safer for
thousands of pilots and millions of passengers. It highlights the agency's
research on weather-related hazards such as windshear and icing and on new
technology to combat them. The displays also explain NASA's research on aging
aircraft, more efficient air traffic control, cockpit automation and human
factors.
In "New And Better Aircraft," guests will learn about NASA's efforts to
revitalize subsonic airplanes and the nation's airspace system. The displays
emphasize NASA's research on advanced composite materials, more efficient, less
noisy engines and new control systems that use fiberoptics and electric
actuators. A special feature details NASA's new initiatives in short-haul
aircraft, including the important general aviation market.
"New Worlds of Flight" is a look at how NASA is paving the way for the
aircraft and aviation systems of tomorrow. There is a special update on the
progress of the National Aero-Space Plane Program, which is generating the
technical foundation for operational, single-stage-to-orbit spaceplanes in the
early decades of the 21st century.
Visitors will find out how the products of NASA research travel from the
lab to the runway in "Putting Technology to Work," a recap of the payoffs of
NASA's aviation research. The displays explain how NASA technology winds up in
products from new engines and nacelles for the Boeing 777 to small aircraft,
automobiles and sailboards.
A special exhibit focuses on NASA's Small Business Innovation Research
Program, which has produced success stories such as the Glasair III LP and the
Pilot Weather Advisory cockpit display for general aviation aircraft
demonstrated at the exhibit. The firms involved will be on hand to talk about
their products.
NASA experts also will be on hand to give forum talks on topics ranging
from general aviation aircraft to the agencyUs SR-71 RBlackbirdsS . The forum
schedule may be obtained from NASA public affairs representatives at Oshkosh.
The presentations by crafts personnel from NASA's research centers are
traditionally a popular feature of the exhibit. This year, NASA's skilled
technicians will again discuss and demonstrate how they make wind tunnel
models, test instruments and other devices that make NASA's advanced
aeronautics research possible.
Although NASA's Oshkosh exhibit is geared toward aviation, there also are
exciting displays of the agency's space programs, including the latest on the
Space Shuttle, Earth and space science studies, space technology and the Space
Station.

7/15/93: DISCOVERY READY TO LAUNCH ON MISSION STS-51
Bruce Buckingham
July 15, 1993
KSC Release No. 85 - 93
The Space Shuttle Discovery is prepared and ready to launch on its 17th
voyage into space. Launch remains scheduled for the opening of a 62-minute
window at 9:22 a.m. EDT from Kennedy Space Center's Pad 39-B.
Preparations for Discovery's flight began just hours after the orbiter
returned from its most recent mission, STS-56, launched on April 8, 1993.
Discovery landed at KSC's Shuttle Landing Facility (SLF) on April 17 and was
towed a few hours later to Orbiter Processing Facility (OPF) bay 3. In the OPF
the vehicle underwent standard turn-around operations and was prepared for
transfer to the Vehicle Assembly Building (VAB) on June 18.
Once in the VAB, Discovery was mated to the external tank (ET) and twin
Solid Rocket Boosters (SRB). Following standard Shuttle interface testing in
the VAB, the entire Shuttle vehicle was rolled out to pad 39-B on June 26. The
day before rollout, the primary payload, the Advanced Communications Technology
Satellite/Transfer Orbit Stage (ACTS/TOS), was delivered to the pad's payload
changeout room. The next day Discovery's payload bay doors were opened and the
ACTS/TOS payload was transferred to the orbiter's payload bay.
Pad 39-B was turned-around in just 4 1/2 days from the time Endeavour was
launched on June 21 and Discovery was rolled out on June 26.
On June 30 the final phase of the Terminal Countdown Demonstration Test
(TCDT) was conducted. The test involved the KSC launch team as well as the
five crew members of mission STS-51. During the TCDT, STS-51 Commander Frank
Culbertson made an orbiter-to-orbiter communications check with STS-57
Commander Ron Grabe, who had just landed the Shuttle Endeavour at KSC's SLF.
At the pad, Discovery underwent typical pre-launch preparations and the
countdown to launch the fifth Space Shuttle mission of the year began on time
at the T-43 hour mark at 9:30 a.m., July 14.
Mission STS-51 is scheduled to last nine days. An additional day on orbit
may be permitted if enough onboard cryogenic reactants are available. Landing
is scheduled to take place at KSC.
The crew for mission STS-51 are: Commander Frank Culbertson, Pilot William
Readdy, and Mission Specialists Daniel Bursch, James Newman and Carl Walz.

The Magellan spacecraft, after more than 450 orbits of
aerobraking, continues successfully to circularize its orbit
around Venus. The Transition Experiment to lower the orbit by
dragging it through the top of the Venusian atmosphere began May
25.
As of today, July 14, the apoapsis, or furthest point in the
elliptical orbit, has been reduced from 8,460 to below 3,200
kilometers (5,245 to 1,904 miles).
The orbit period has been reduced from 194 minutes to 124
minutes. There are now 11.5 orbits per day.
This week, Magellan is passing through a phase in which the
local gravity field changes. That has caused the spacecraft, at
its closest point to the planet, to drift upward instead of
toward the planet.
Project officials said they planned to perform a maneuver
Thursday (July 15) to keep the orbit change on course for
achieving a 102-minute orbit by July 27.
At the time, the "end game" will begin to place Magellan in
the desired orbit for collecting gravity data in the higher
latitudes of Venus. The fine tuning adjustments of the end game
are designed to achieve an orbit which varies from 200 to 650
kilometers (124 to 403 miles) from the surface with an orbital
period of 94 minutes.
All spacecraft systems remained normal with temperatures
well within expected ranges. Propellant usage was running between
10 and 20 grams per orbit, and there was a 17-kilogram (37.5
pounds) margin -- enough thruster propellant to maintain Magellan
through several Venus cycles.

1993-94 NASA EDUCATION VIDEOCONFERENCE SERIES
UPDATE FOR TEACHERS
A Series of One Hour Staff Development Programs for Elementary and
Secondary School Faculty
Topics and Dates
MISSION TO PLANET EARTH
OCT. 5, 1993
Curriculum Focus is Earth Systems Science
Our planet is experiencing profound environmental changes. NASA's Mission to
Planet Earth program will enable us to observe, understand, and predict change
on Earth. Mission to Planet Earth is part of an international effort designed
to assure that we enter the 21st Century with a better understanding of
environmental change on the local, regional, and global scale. This
videoconference will discuss global change, the Mission to Planet Earth
project, and how data is turned into scientifically useful information.
ASTRONOMY
NOV. 30, 1993
Curriculum Focus is Mathematics, Physics
NASA astronomy research programs, including the Cosmic Background Explorer
(COBE), the Hubble Space Telescope (HST), and the Compton Gamma Ray Observatory
(CGRO), have been dramatically advancing human knowledge about the origin,
nature, and evolution of our Universe. COBE has provided exciting evidence for
the Big Bang Theory. HST is making discoveries about the planets of our solar
system, the stars and interstellar medium of our galaxy, and the countless
other galaxies beyond our own, some of which may have Black Holes at their
center. CGRO is investigating the most energetic systems and violent events in
our Universe. This program will discuss the discoveries of HST, COBE, CGRO, and
other NASA astronomy efforts.
LIFE SCIENCES RESEARCH
FEB. 8, 1994
Curriculum Focus is Life Sciences
NASA research in the life sciences is designed to further our knowledge of the
requirements for humans to live and work in space. Results from this research
related to atmosphere, microgravity, and radiation are testing concepts and
providing answers that will be applied aboard future Space Shuttle and other
human space flight missions. This program will discuss applications of this
research.
AERONAUTICS HIGH-SPEED RESEARCH
MAY 3, 1994
Curriculum Focus is Mathematics, Chemistry
High-Speed research is underway by NASA, in cooperation with the U.S.
aeronautics industry, to develop the technology base for construction of a
supersonic transport for long-range commercial routes, such as from the U.S. to
the Orient. Phase One is addressing environmental concerns about the effects of
emissions on the atmosphere and airport noise level. This videoconference will
explain the need for capabilities in areas such as chemistry, materials, fluids
and atmospheric sciences, along with using such sophisticated tools as wind
tunnels and computational methods, to develop an environmentally-sound aircraft
system.
