KENNEDY SPACE CENTER, FLA. -- At Launch Complex 40 on Cape Canaveral Air Station, one of three Radioisotope Thermoelectric Generators (RTGs) is being installed on the Cassini spacecraft. RTGs are lightweight, compact spacecraft electrical power systems that have flown successfully on 23 previous U.S. missions over the past 37 years. These generators produce power by converting heat into electrical energy, the heat is provided by the natural radioactive decay of plutonium-238 dioxide, a non-weapons-grade material. RTGs enable spacecraft to operate at significant distances from the Sun where solar power systems would not be feasible. Cassini will travel two billion miles to reach Saturn and another 1.1 billion miles while in orbit around Saturn. Cassini is undergoing final preparations for liftoff on a Titan IVB/Centaur launch vehicle, with the launch window opening at 4:55 a.m. EDT, Oct. 13. |

Inspecting Cassini's nuclear power source |
| Full Description |
Environmental Health Specialist Jamie A. Keeley of EG&G Florida Inc., KSC's base operations contractor, uses an ion chamber dose rate meter to measure radiation levels in one of the three radioisotope thermoelectric generators (RTGs) that will provide electrical power to the Cassini spacecraft. Technicians tested and monitored four RTGs, including one spare, in the Radioisotope Thermoelectric Generator Storage building in KSC's Industrial Area. The RTGs use heat from the natural decay of plutonium to generate electric power. This nuclear powered system enables the spacecraft to operate far from the Sun, where solar power systems are not feasible. Similar RTGs powered the Galileo and Ulysses spacecraft. A close-up study of Saturn and its moons, the Cassini/Huygens mission launched from Cape Canaveral Air Station in October 1997 and reached the Saturnian system in July 2004 for four years of observation. Scientific instruments carried aboard the Cassini orbiter will study Saturn's atmosphere, magnetic field, rings, and several moons, while the Huygens probe will separate and land on the surface of Titan, Saturn's largest moon. The Cassini-Huygens mission owes its name to the Dutch astronomer Christiaan Huygens and Italian astronomer Giovanni Domenico Cassini. Both had spectacular careers as observers of the heavens, which included important discoveries about Saturn and its satellites. Huygens (1629-1695) discovered Saturn's largest moon, Titan, in 1655 and in 1656 described the shape and phase changes of Saturn's rings. Cassini (1625-1712) was the first to observe four of Saturn's moons, Iapetus, Rhea, Tethys, and Dione, in the 1670s and 1680s. He also, in 1675, discovered the gap in Saturn's rings, now called the Cassini Division, and proposed that the rings were formed from many tiny particles. Cassini-Huygens is a joint mission of NASA, the European Space Agency (ESA), and the Italian Space Agency, Agenzia Spaziale Italiana (ASI). JPL is managing the Cassini project for NASA. The mission was proposed in November 1982 by a group of European and American scientists from the European Science Foundation and the National Academy of Sciences. The Solar System Exploration Committee of the NASA Advisory Council endorsed the idea in April 1983, and NASA and ESA began a joint assessment study in 1984. ESA officially adopted the project in November 1988, and Congress approved funding for NASA's portion of the mission in FY 89. |

Viking Pre-Launch Test Fligh
| Title |
Viking Pre-Launch Test Flight |
| Full Description |
The Titan booster is a two-stage liquid-fueled rocket, with two additional large, solid-propellant rockets attached. It is a member of the Titan family that was used in NASA's Gemini program. The Centaur is a liquid oxygen- liquid hydrogen, high- energy upper stage used on Surveyor flights to the Moon and on Mariner flights to Mars. At liftoff, the solid rockets provide 9.61 million newtons (2.16 million pounds) of thrust. When the solids burn out, the first stage of the Titan booster ignites, and followed by the second-stage ignition as the first stage shuts down. The Centaur ignites on second stage shutdown to inject the spacecraft into orbit. Then after a 30-minute coast around the Earth into position for re-start, the Centaur re-ignites to propel Viking on its Mars trajectory. Once this maneuver is completed the spacecraft separates from the Centaur, which subsequently is deflected away from the flight path to prevent its impact on the surface of Mars. Shortly after separating from the Centaur, the orbiter portion of the combined orbiter-lander spacecraft orients and stabilizes the spacecraft by using the Sun and a very bright star in the southern sky, Canopus, for celestial reference. For more information about Titan and Centaur, please see Chapters 4 and 8, respectively, in Roger Launius and Dennis Jenkins' book To Reach the High Frontier published by The University Press of Kentucky in 2002. |

First Map of Subsurface Flow
| Description |
First Map of Subsurface Flows in the Sun's Convection Zone This map provides the first view of an important part of the Sun's interior, the region call the convection zone. The convection zone lies directly beneath the photosphere, which forms the Sun's visible surface and effectively hides what is below. As a result, very little is known about the convection zone's internal structure, despite the fact that it is the source of sunspots, solar flares and most other forms of solar activity that affect Earth. "This map is important for two reasons," said team member Alexander G. Kosovichev, a senior research scientist at Stanford. "First, it gives us a new window into the solar interior. Second, it appears to provide support for one of two theories that have been proposed to explain the dynamics of this region." Kosovichev and Thomas L. Duvall, Jr., a scientist at Goddard Space Flight Center in Greenbelt, MD., reported the successful mapping effort on Tuesday, June 11, at the annual meeting of the American Astronomical Society held in Madison, Wis. Also collaborating on the project were Stanford physics research Professor Philip H. Scherrer and Peter N. Milford of Parallel rules Inc. of Los Gatos, Calif. The Scientists constructed the map using detailed data of the Sun's surface motion provided by an instrument called a doppler imager carried aboard the Solar and Heliospheric Observatory. SOHO is a $1.1 billion spacecraft that is a joint project of the European Space Agency and NASA. The observatory was launched from the Kennedy Space Center in Florida last December and now has taken up a station 930,000 miles sunward from the Earth. Its mission is to provide new knowledge about the Sun, Earth's nearest star. Accordfing to current understanding, the Sun's interior is divided into threevery different regions: The core, which extends out about 100,000 miles for the Sun's center, contains about half of its mass and generates about 98 percent of its energy through processes of nuclear fusion. Next, there is a relatively stable radiative zone that conducts heat smoothly from the core to within 125,000 miles of the Sun's surface. Finally, there is the convection zone, where the Sun's gases boil much like water in a pot on the stove, forming giant cells of rising and falling gases that carry heat to the surface. Most knowledge about the Sun has come form studying the light emitted from the photosphere. Although the photosphere is only about 200 miles thick, it has proven very difficult for scientists to pierce its fiery veil. In the last 30 years, solar scientists have developed a technique called global helioseismology, which uses low-pitched sound waves to study the Sun's deep interior. This method has allowed researchers to measure limportant properties of the solar interior, such as temperature and rotational variation. But it has not provided much information about the convection layer. The Michelson Doppler Imager on board SOHO, built by Stanford and, Lockheed Palo Alto Research Laboratory, measures lthe vertical motion of the Sun's surface at a million different points once a minute. The researchers used this information to calculate the time it takes sounds to travel between many different points on the solar surface. Because the paths of these sound waves loop down into the interior, the scientists can use this information to map the temperature and flow patterns beneath the surface. "We can do this by using a maghematical technique similar to that used in computer-aided tomography to produce CAT scans," Duvall said. Thus, after a solid week of number crunching on a supercomputer, the researchers were able to reconstruct a picture of the three-dimensional flows in a volume at the Sun's equator that extends for 110,000 miles horizontally and penetrates to a depth of 4,800 miles below the photosphere. Additional observations at other times and locations are needed to determine whether the features that the map reveals are characteristic, the scientists stress. Nevertheless, it provides a tantalizing first view of how the convection zone is organized internally. For example, the map provides the first direct evidence for the depth of the features called granuled, which cover the face of the Sun and are typically about 1,000 miles across. Granules typically are organized into larger domaine called supergranules that average about 15,000 miles across. Theoretical calculations predicted that supergranule thickness should be between 25 and 30 percent of their width. But the mapping effort suggests that they are shaped more like pancakes, with a thickness only one-tenth of their width. More significantly, the new map shows no evidence of giant convection cells that had been predicted by a popular theory called the global circulation model, the scientists said. It does, however, show evidence of narrow plumes of cooler gases streaming downward toward the boundary with the radiative layer - a view consistent with the result of some numerical simulations of the region. According to the simulations, these plumes extend all the way down to the boundary between the convective and radiative zones. When the material in the plumes plunges into the radiative zone, it may create the magnetic loops that produce the fiery flares that rise above the Sun's surface and that are intimately involved in the formation of sunspots. Surprisingly, however, the plumes appear to originate from the middle of the supergranuled, rather than at their edges as had been proposed. Onboard SOHO, the doppler imager has begun a continuous, 60-day observing program. This will allow the researchers to make a "movie" of this part of the convection zone so that they can observe how its structure changes over time. |

| Abstract |
The Apollo 17 spacecraft was launched from the Kennedy Space Center at midnight on December 7th, 1972. Just hours after lift-off, the command module aligned with the Earth and Sun, allowing the crew to photograph Earth in full light. For the first time in an Apollo mission, the Antarctic continent was visible allowing for a photo to be taken by the orbiting astronauts. The photo was taken at about 18,000 statute miles away from Earth. Virtually every picture showing the full Earth is derived from this one photograph. Television, newspapers, websites, and marketing material have all used this photograph over the years. Geostationary weather satellites, Galileo, and many other spacecraft have returned great pictures of the full Earth from space, but this image is still the number one requested photo in the NASA photo archives. |

Inside the Station, the STS-114 crew conducted joint operations with the Expedition 11 crew. They unloaded fresh supplies from the Shuttle and the Raffaello Multi-Purpose Logistics Module. Before Discovery undocked, the crews filled Raffeallo with unneeded items and returned to Shuttle payload bay. Discovery launched on July 26 and spent almost 14 days on orbit. |

| Project Description |
NASA uses two modified Boeing 747 jetliners, originally manufactured for commercial use, as Space Shuttle Carrier Aircraft (SCA). One is a 747-100 model, while the other is designated a 747-100SR (short range). The two aircraft are identical in appearance and in their performance as Shuttle Carrier Aircraft. The 747 series of aircraft are four-engine intercontinental-range swept-wing "jumbo jets" that entered commercial service in 1969. The SCAs are used to ferry space shuttle orbiters from landing sites back to the launch complex at the Kennedy Space Center, and also to and from other locations too distant for the orbiters to be delivered by ground transportation. The orbiters are placed atop the SCAs by Mate-Demate Devices, large gantry-like structures which hoist the orbiters off the ground for post-flight servicing, and then mate them with the SCAs for ferry flights. Features which distinguish the two SCAs from standard 747 jetliners are: - Three struts, with associated interior structural strengthening, protruding from the top of the fuselage (two aft, one forward) on which the orbiter is attached - Two additional vertical stabilizers, one on each end of the standard horizontal stabilizer, to enhance directional stability - Removal of all interior furnishings and equipment aft of the forward No. 1 doors - Instrumentation used by SCA flight crews and engineers to monitor orbiter electrical loads during the ferry flights and also during pre- and post-ferry flight operations. The two SCAs are under the operational control of NASA's Johnson Space Center, Houston, Tex. NASA 905 NASA 905 was the first SCA. It was obtained from American Airlines in 1974. Shortly after it was accepted by NASA it was flown in a series of wake vortex research flights at the Dryden Flight Research Center in a study to seek ways of reducing turbulence produced by large aircraft. Pilots flying as much as several miles behind large aircraft have encountered wake turbulence that have caused control problems. The NASA study helped the Federal Aviation Administration modify flight procedures for commercial aircraft during airport approaches and departures. Following the wake vortex studies, NASA 905 was modified by Boeing to its present SCA configuration and the aircraft was returned to Dryden for its role in the 1977 Space Shuttle Approach and Landing Tests (ALT). This series of eight captive and five free flights with the orbiter prototype Enterprise, in addition to ground taxi tests, validated the aircraft's performance as an SCA, in addition to verifying the glide and landing characteristics of the orbiter configuration -- paving the way for orbital flights. A flight crew escape system, consisting of an exit tunnel extending from the flight deck to a hatch in the bottom of the fuselage, was installed during the modifications. The system also included a pyrotechnic system to activate the hatch release and cabin window release mechanisms. The flight crew, escape system was removed from the NASA 905 following the successful completion of the ALT program. NASA 905 was the only SCA used by the space shuttle program until November 1990, when NASA 911 was delivered as an SCA. Along with ferrying Enterprise and the flight-rated orbiters between the launch and landing sites and other locations, NASA 905 also ferried Enterprise to Europe for display in England and at the Paris Air Show. NASA 911 The second SCA is designated NASA 911. It was obtained by NASA from Japan Airlines (JAL) in 1989. It was also modified by Boeing Corporation. It was delivered to NASA 20 November 1990. |

STS-64 Landing at Edwards
| Photo Description |
The Space Shuttle Discovery settles to the main runway at Edwards, California, at 2:13 p.m. (PDT) 20 September 1994, to conclude mission STS-64. The spacecraft, with a crew of six, was launched into a 57-degree high inclination orbit from the Kennedy Space Center, Florida, at 3:23 p.m. (PDT), 9 September 1994. The mission featured the study of clouds and the atmosphere with a laser beaming system called Lidar In-Space Technology Experiment (LITE), and the first untethered space walk in over ten years. A Spartan satellite was also deployed and later retrieved in the study of the sun's corona and the solar wind. The mission was scheduled to end Sunday, 18 September, but was extended one day to continue science work. Bad weather at the Kennedy Space Center on September 19, forced a one-day delay to September 20, with a weather divert that day to Edwards. Mission commander was Richard Richards, the pilot Blaine Hammond, while mission specialists were Jerry Linenger, Susan Helms, Carl Meade, and Mark Lee. |

The early morning sun found hundreds of spectators on the beaches and roadways near the NASA Kennedy Space Center (KSC) where they had camped the night before to witness history by watching the epic beginning of the journey of Apollo 11. The first manned lunar landing mission launched from KSC via the Marshall Space Flight Center (MSFC) developed Saturn V launch vehicle on July 16, 1969 and safely returned to Earth on July 24, 1969. Aboard the space craft were astronauts Neil A. Armstrong, commander, Michael Collins, Command Module (CM) pilot, and Edwin E. (Buzz) Aldrin Jr., Lunar Module (LM) pilot. The CM, ?Columbia?, piloted by Collins, remained in a parking orbit around the Moon while the LM, ?Eagle??, carrying astronauts Armstrong and Aldrin, landed on the Moon. On July 20, 1969, Armstrong was the first human to ever stand on the lunar surface, followed by Aldrin. During 2½ hours of surface exploration, the crew collected 47 pounds of lunar surface material for analysis back on Earth. With the success of Apollo 11, the national objective to land men on the Moon and return them safely to Earth had been accomplished. |

The Space Shuttle Discovery, STS-102 mission, clears launch pad 39B at the Kennedy Space Center as the sun peers over the Atlantic Ocean on March 8, 2001. STS-102's primary cargo was the Leonardo, the Italian Space Agency built Multipurpose Logistics Module (MPLM). The Leonardo MPLM is the first of three such pressurized modules that will serve as the International Space Station's (ISS') moving vans, carrying laboratory racks filled with equipment, experiments, and supplies to and from the Station aboard the Space Shuttle. The cylindrical module is approximately 21-feet long and 15- feet in diameter, weighing almost 4.5 tons. It can carry up to 10 tons of cargo in 16 standard Space Station equipment racks. Of the 16 racks the module can carry, 5 can be furnished with power, data, and fluid to support refrigerators or freezers. In order to function as an attached station module as well as a cargo transport, the logistics module also includes components that provide life support, fire detection and suppression, electrical distribution, and computer functions. NASA's 103rd overall flight and the eighth assembly flight, STS-102 was also the first flight involved with Expedition Crew rotation. The Expedition Two crew was delivered to the station while Expedition One was returned home to Earth. |

Anticrepuscular Rays Over Florida |
| Explanation |
What's happening over the horizon? Although the scene may appear somehow supernatural [ http://www.badastronomy.com/bad/misc/astrology.html ], nothing more unusual is occurring than a setting Sun [ http://antwrp.gsfc.nasa.gov/apod/ap980526.html ] and some well placed clouds. Strangely, the actual sunset was occurring in the opposite direction from where the camera was pointing. Pictured above are anticrepuscular rays [ http://www.sundog.clara.co.uk/atoptics/anti1.htm ]. To understand them, start by picturing common crepuscular rays [ http://www.ems.psu.edu/~demark/471/CrepuscularRays.html ] that are seen any time that sunlight pours though scattered clouds. Now although sunlight indeed travels along straight lines [ http://www.theory.caltech.edu/people/patricia/grelb.html ], the projections of these lines onto the spherical sky [ http://math.rice.edu/~pcmi/sphere/ ] are great circles [ http://en.wikipedia.org/wiki/Great_circles ]. Therefore, the crepuscular rays [ http://www.allthesky.com/atmosphere/sunrays.html ] from a setting (or rising) sun [ http://antwrp.gsfc.nasa.gov/apod/ap030123.html ] will appear to re-converge on the other side of the sky. At the anti-solar point 180 degrees around from the Sun [ http://antwrp.gsfc.nasa.gov/apod/sun.html ], they are referred to as anticrepuscular rays [ http://www.sundog.clara.co.uk/atoptics/antray2.htm ]. While enjoying the sunset after visiting NASA's Kennedy Space Center [ http://www.nasa.gov/centers/kennedy/home/index.html ] in Florida [ http://en.wikipedia.org/wiki/Florida ], the photographer chanced to find that an even more spectacular sight was occurring in the other direction just over the Atlantic Ocean [ https://www.cia.gov/cia/publications/factbook/geos/zh.html ] -- a particularly vivid set of anticrepuscular rays [ http://www.gcrg.org/bqr/6-4/optics.htm ]. |

The change of season is known as an equinox as the Sun rises [ http://solar.physics.montana.edu/YPOP/Classroom/Lessons/ Sundials/sundials.html ] due east on the horizon and sets due west -- providing an equal night [ http://antwrp.gsfc.nasa.gov/apod/ap000923.html ], 12 night and 12 daylight hours, for both northern and southern hemispheres. In this picture [ http://www-pao.ksc.nasa.gov/kscpao/captions/ 2001/mar/01pp0440.htm ] from March 8, the Sun peers over the eastern horizon at the space shuttle Discovery's dramatic morning launch on mission STS-102. Having delivered supplies and taxied crew to the International Space Station [ http://antwrp.gsfc.nasa.gov/apod/ap010228.html ], Discovery will remain in orbit for this first day of northern hemisphere Spring.

But this is not a picture of that launch [ http://spaceflight.nasa.gov/gallery/images/shuttle/sts-107/ html/03pd0113.html ]! It was taken on the morning of January 16 though, at sunrise, looking eastward toward Lake Ontario from just outside of Caledon, Ontario, Canada. In the picture a sun pillar [ http://ww2010.atmos.uiuc.edu/(Gh)/ guides/mtr/opt/ice/sp.rxml ], sunlight reflecting from ice crystals [ http://www.sundog.clara.co.uk/halo/pillar.htm ] gently falling through the cold air, seems to shoot above the fiery Sun still low [ http://antwrp.gsfc.nasa.gov/apod/ap020902.html ] on the horizon. By chance, fog [ http://antwrp.gsfc.nasa.gov/apod/ap021122.html ] and clouds forming over the relatively warm lake look like billowing smoke from a rocket's exhaust plume [ http://antwrp.gsfc.nasa.gov/apod/ap020308.html ] and complete the launch illusion.

In orbit, the Space Shuttles circle the earth at a speed of 17,500 miles per hour with each orbit taking about 90 minutes. A Space Shuttle crew sees a sunrise or sunset every 45 minutes. When Space Shuttle flights began in April 1981, Dryden Flight Research Center, Edwards, California, was the primary landing site for the Shuttles. Now Kennedy Space Center, Florida, is the primary landing site with Dryden remaining as the principal alternate landing site. |

STS-64 and 747-SCA Ferry Fli
| Title |
STS-64 and 747-SCA Ferry Flight Takeoff |
| Description |
The Space Shuttle Discovery, mated to NASA's 747 Shuttle Carrier Aircraft (SCA), takes to the air for its ferry flight back to the Kennedy Space Center in Florida. The spacecraft, with a crew of six, was launched into a 57-degree high inclination orbit from the Kennedy Space Center, Florida, at 3:23 p.m., 9 September 1994. The mission featured the study of clouds and the atmosphere with a laser beaming system called Lidar In-Space Technology Experiment (LITE), and the first untethered space walk in ten years. A Spartan satellite was also deployed and later retrieved in the study of the sun's corona and solar wind. The mission was scheduled to end Sunday, 18 September, but was extended one day to continue science work. Bad weather at the Kennedy Space Center on 19 September, forced a one-day delay to September 20, with a weather divert that day to Edwards. Mission commander was Richard Richards, the pilot Blaine Hammond, while mission specialists were Jerry Linenger, Susan Helms, Carl Meade, and Mark Lee. Space Shuttles are the main element of America's Space Transportation System and are used for space research and other space applications. The shuttles are the first vehicles capable of being launched into space and returning to Earth on a routine basis. Space Shuttles are used as orbiting laboratories in which scientists and mission specialists conduct a wide variety of scientific experiments. Crews aboard shuttles place satellites in orbit, rendezvous with satellites to carry out repair missions and return them to space, and retrieve satellites and return them to Earth for refurbishment and reuse. Space Shuttles are true aerospace vehicles. They leave Earth and its atmosphere under rocket power provided by three liquid-propellant main engines with two solid-propellant boosters attached plus an external liquid-fuel tank. After their orbital missions, they streak back through the atmosphere and land like airplanes. The returning shuttles, however, land like gliders, without power and on runways. Other rockets can place heavy payloads into orbit, but, they can only be used once. Space Shuttles are designed to be continually reused. When Space Shuttles are used to transport complete scientific laboratories into space, the laboratories remain inside the payload bay throughout the mission. They are then removed after the Space Shuttle returns to Earth and can be reused on future flights. Some of these orbital laboratories, like the Spacelab, provide facilities for several specialists to conduct experiments in such fields as medicine, astronomy, and materials manufacturing. Some types of satellites deployed by Space Shuttles include those involved in environmental and resources protection, astronomy, weather forecasting, navigation, oceanographic studies, and other scientific fields. The Space Shuttles can also launch spacecraft into orbits higher than the Shuttle's altitude limit through the use of Inertial Upper Stage (IUS) propulsion units. After, release from the Space Shuttle payload bay, the IUS is ignited to carry the spacecraft into deep space. The Space Shuttles are also being used to carry elements of the International Space Station into space where they are assembled in orbit. The Space Shuttles were built by Rockwell International's Space Transportation Systems Division, Downey, California. Rockwell's Rocketdyne Division (now part of Boeing) builds the three main engines, and Thiokol, Brigham City, Utah, makes the solid rocket booster motors. Martin Marietta Corporation (now Lockheed Martin), New Orleans, Louisiana, makes the external tanks. Each orbiter (Space Shuttle) is 121 feet long, has a wingspan of 78 feet, and a height of 57 feet. The Space Shuttle is approximately the size of a DC-9 commercial airliner and can carry a payload of 65,000 pounds into orbit. The payload bay is 60 feet long and 15 feet in diameter. Each main engine is capable of producing a sea level thrust of 375,000 pounds and a vacuum (orbital) thrust of 470,000 pounds. The engines burn a mixture of liquid oxygen and liquid hydrogen. In orbit, the Space Shuttles circle the earth at a speed of 17,500 miles per hour with each orbit taking about 90 minutes. A Space Shuttle crew sees a sunrise or sunset every 45 minutes. When Space Shuttle flights began in April 1981, Dryden Flight Research Center, Edwards, California, was the primary landing site for the Shuttles. Now Kennedy Space Center, Florida, is the primary landing site with Dryden remaining as the principal alternate landing site. |

STS-82 Discovery Rollout to Pad 39-A |
| Description |
The rising sun and some scattered clouds provide a picturesque backdrop for the Space Shuttle Discovery as it travels along the Crawlerway toward Launch Pad 39A in preparation for the STS-82 mission. The Shuttle is on a Mobile Launch Platform, and the entire assemblage is being carried by a large tracked vehicle called the Crawler Transporter. A seven-member crew will perform the second servicing of the orbiting Hubble Space Telescope (HST) during the 10-day STS-82 flight, which is targeted for a Feb. 11 liftoff. |

STS-92 - Orbiter in Mate-Dem
| Title |
STS-92 - Orbiter in Mate-Demate Device (MDD) |
| Description |
The early-morning Sun bathes the Space Shuttle Discovery in hues of purple, pink and gold as it is encased in the Mate-Demate Device (MDD) at NASA's Dryden Flight Research Center at Edwards, California. The gantry-like MDD structure is used to prepare the shuttle for its ferry flight back to the Kennedy space Center in Florida, including mounting the shuttle atop NASA's modified Boeing 747 Shuttle Carrier Aircraft. STS-92 was the 100th mission since the fleet of four Space Shuttles began flying in 1981. (Due to schedule changes, missions are not always launched in the order that was originally planned.) The almost 13-day mission, the 46th Shuttle mission to land at Edwards, was the last construction mission for the International Space Station prior to the first scientists taking up residency in the orbiting space laboratory the following month. The seven-member crew on STS-92 included mission specialists Koichi Wakata, Michael Lopez-Alegria, Jeff Wisoff, Bill McArthur and Leroy Chiao, pilot Pam Melroy and mission commander Brian Duffy. |

STS-92 - Shuttle Carrier Air
| Title |
STS-92 - Shuttle Carrier Aircraft (SCA) |
| Description |
One of NASA's two modified Boeing 747 Shuttle Carrier Aircraft is bathed in the morning Sun at NASA's Dryden Flight Research Center at Edwards, California. The modified jumbo jetliners are used to ferry the Space Shuttle orbiters between Dryden and the Kennedy Space Center in Florida and Boeing's Reusable Space Systems modification facility at Palmdale, California. Features which distinguish the two SCAs from standard 747 jetliners are three struts, with associated interior structural strengthening, which protrude from the top of the fuselage (two aft, one forward) on which the orbiter is attached, and two additional vertical stabilizers, one on each end of the standard horizontal stabilizer, to enhance directional stability. All interior furnishings and equipment aft of the forward No. 1 doors have also been removed to reduce weight. The two SCAs are under the operational control of NASA's Johnson Space Center, Houston, Texas. STS-92 was the 100th mission since the fleet of four Space Shuttles began flying in 1981. (Due to schedule changes, missions are not always launched in the order that was originally planned.) The almost 13-day mission, the 46th Shuttle mission to land at Edwards, was the last construction mission for the International Space Station prior to the first scientists taking up residency in the orbiting space laboratory the following month.
