July 15, 1993 Michael Mewhinney Ames Research Center, Mountain View, Calif. Pat Cariseo Federal Aviation Administration, Washington, D.C. 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. - end - Source:NASA Spacelink Modem:205-895-0028 Internet:192.149.89.61 =--=--=-END-=--=--= =--=--=START=--=--= NASA Spacelink File Name:930715.SHU 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. SUMMARY OF HOLDS AND HOLD TIMES REMAINING FOR STS-51 T-TIME ------- LENGTH OF HOLD ---- HOLD BEGINS ---- HOLD ENDS T-19 hours --- 4 hours ----------- 5:30 pm Thurs.- 9:30 pm Thurs.

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 temperatures well within expected ranges. * * * * * * * * * * * * * * * * On July 19-20, NASA and the Federal Aviation Administration (FAA) will cohost a briefing at the Ames Research Center for aviation industry representatives about a NASA-developed automated air traffic control tool.

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.

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.

MAGELLAN STATUS REPORT July 14, 1993 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.

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.
