P-34681 Range: 870,000 kilometers (540,000 miles) This image of Neptune's irregularly-shaped satellite 1989N1 taken by Voyager 2 shows a resolution of 8 kilometers (5 miles) per pixel. The satellite has an average radius of about 200 kilometers (120 miles) and is uniformly dark with an albedo of about 6 percent. The irregular shape suggests that 1989N1 has been cold and rigid throughout its history and subject to significant impact cratering. ARC-1989-A89-7034

KENNEDY SPACE CENTER, FLA. -- Towering atop the mobile launcher platform and crawler transporter, Space Shuttle Discovery rolls out of the Vehicle Assembly Building on its way to Launch Pad 39B which is 4.2 miles (6.8 kilometers) away. While at the pad, the orbiter, external tank and solid rocket boosters will undergo final preparations for the STS-103 launch targeted for Dec. 6, 1999, at 2:37 a.m. EST. The mission is a "call-up" due to the need to replace portions of the pointing system the gyros which have begun to fail on the Hubble Space Telescope. Although Hubble is operating normally and conducting its scientific observations, only three of its six gyroscopes are working properly. The gyroscopes allow the telescope to point at stars, galaxies and planets. The STS-103 crew will also be installing a Fine Guidance Sensor, a new enhanced computer, a solid-state digital recorder, and a new spare transmitter to replace older equipment, and replacing degraded insulation on the telescope with new thermal insulation. The crew will also install a Battery Voltage/Temperature Improvement Kit to protect the spacecraft batteries from overcharging and overheating when the telescope goes into a safe mode. Four EVA's are planned to make the necessary repairs and replacements on the telescope. Comprising the STS-103 crew are Commander Curtis L. Brown Jr., Pilot Scott J. Kelly, Mission Specialist Steven L. Smith, Mission Specialist C. Michael Foale (Ph.D.), Mission Specialist John M. Grunsfeld (Ph.D.), Mission Specialist Claude Nicollier of Switzerland, with the European Space Agency, and Mission Specialist Jean-François Clervoy of France, with the European Space Agency KSC-99padig031

KENNEDY SPACE CENTER, FLA. - Space Shuttle Atlantis crawls at less than 1 mph (<1.5 kilometers) along the crawlerway to the launch pad.  The Shuttle sits on top of the Mobile Launcher Platform, which rests on the crawler-transporter. Atlantis is scheduled for launch April 4 on mission STS-110, which will install the S0 truss, the framework that eventually will hold the power and cooling systems needed for future international research laboratories on the International Space Station.  The  Canadarm2 robotic arm will be used exclusively to hoist the 13-ton truss from the payload bay to the Station.  The S0 truss will be the first major U.S. component launched to the Station since the addition of the Quest airlock in July 2001.  The four spacewalks planned for the construction will all originate from the airlock.  The mission will be Atlantis' 25th trip to space KSC-02pd0276

ISS012-E-18779 (28 Feb. 2006) --- Winter in the Dasht-e-Lut Desert, eastern Iran is featured in this image photographed by an Expedition 12 crew member on the International Space Station. The image takes advantage of the low angle of illumination to reveal linear geological structures of the Iranian mountain range bordering the western edge of the basin known as Dasht-e-Lut. The range rises 1818 meters (6000 feet) above sea level and lies 750 kilometers (466 miles) north of the Persian Gulf. The convoluted appearance results from erosion of folded and faulted rocks – softer rocks erode away quickly, leaving more resistant rock to form linear ridges perpendicular to the direction of compression. While not a major oil producing region like the Zagros Fold Belt to the southwest, the mountains of east-central Iran contain economically important deposits of copper and other metals. Little vegetation is visible from space in the arid interior basin of the Dasht-e-Lut. Iran is climatically part of the Afro-Asian belt of deserts that stretch from the Cape Verde islands off West Africa all the way to Mongolia near Beijing. The patchy, elongated, light-colored feature in the foreground (parallel to the mountain range) is the northernmost of the Dasht dry lakes that stretch southward 300 kilometers (186 miles). High country is the source of precipitation-derived water in all near-tropical deserts. Agricultural fields (small dark patches in the image) that depend on this precipitation are located down slope near the margin of the dry, salty soils of the lake. iss012e18779

America's petroleum industries pour out fuel and lubricants for the United Nations. Railroad cars stand on a side track ready to receive cargoes of gasoline stored in large spherical tanks at the refinery of one of the principal U.S. oil companies. The cars will speed the gasoline across the American continent to seaports where it will be loaded onto tanker ships for conveyance overseas to the armed forces of the United Nations. Gasoline totals have reached new records since the U.S. entered the war. Besides the enormous amounts required to fuel the 180,000 planes American factories have turned out since December 7, 1941, large supplies of fuel are needed for naval vessels, merchant ships, tanks and mechanized units in the field. It takes 25,000 gallons of gasoline to move a single U.S. Army tank division 100 miles (160 kilometers)

Voyager 1 Image of Jupiter and two of its satellites (Io, left, and Europa). Io is about 350,000 kilometers (220,000 miles) above Jupiter's Great Red Spot; Europa is about 600,000 kilometers (375,000 miles) above Jupiter's clouds. Although both satellites have about the same brightness, Io's color is very different from Europa's. Io's equatorial region show two types of material -- dark orange, broken by several bright spots -- producing a mottled appearance. The poles are darker and reddish. Preliminary evidence suggests color variations within and between the polar regions.  Io's surface composition is unknown, but scientists believe it may be a mixture of salts and sulfur.  Erupoa is less strongly colored, although still relatively dark at short wavelengths. Markings on Eruopa are less evident that on the other satellites, although this picture shows darker regions toward the trailing half of the visible disk. Jupiter at this point is about 20 million kilometers (12.4 million miles) from the spacecraft.  At this resolution (about 400 kimometers or 250 miles) there is evidence of circular motion in Jupiter's atmosphere. While the dominant large-scale motions are west-to-east, small-scale movement includes eddy-like circulation within and between the bands.  (JPL ref: P-21082) ARC-1979-AC79-0164-1

This mosaic of Jupiter was assembled from nine individual photos taken through an orange filter by Voyager 1 on Feb. 6, 1979, when the spacecraft was 4.7 million miles (7.8 million kilometers) from Jupiter.  Distortion of the mosaic, especially where portions of the limb have been fitted together, is caused by rotation of the planet during the 96-second intervals between individual pictures.  The large atmospheric feature just below and to the right of center is the Great Red Spot.  The complex structure of the cloud formations seen over the entire planet gives some hint of the equally complex motions in the Voyager 1 time-lapse photography.  The smallest atomospheric features seen in this view are approximately 85 miles (140 kilometers) across.  Voyager project is managed and controlled by Jet Propulsion Laboratory for NASA's Office of Space Science.  (JPL ref. No. P-21146) ARC-1979-A79-7029

P-21747 BW Range: 2,200,000 miles This image shows a region of the Jovian atmosphere from approximately 25° N to the equatorial region. The north temperate jet, at approximately 23° N, where the wind speed is about 150 meters per second, is seen as a dark brown line from the left-hand edge to the right-hand corner of the picture. The wispy clouds of the north equatorial belt appear as shades of brown. The lower right-hand corner of the image shows the brighter (white) clouds of the equatorial region. A small blue area is apparent near the lower edge, which corresponds to a region free of the upper clouds, where it is possible to penetrate to cloud layers approximately 60 kilometers below the visible surface.

P-21751 C Range: 1.2 million kilometers This Voyager 2 color photo of Ganymede, the largest Galilean satellite, shows a large dark circular feature about 3200 kilometers in diameter with narrow closely-spaced light bands traversing its surface. The bright spots dotting the surface are relatively recent impact craters, while the lighter circular areas may be older impact areas. The light branching bands are ridged and grooved terrain first seen on Voyager 1 and are younger than the more heavily cratered dark regions. The nature of the brightish region covering the northern part of the dark circular fature is uncertain, but it may be some type of condensate. Most of the features seen on the surface of Ganymede are probably both internal and external responses of the very thick icy layer which comprises the crust of this satellite. ARC-1979-AC79-7083

Range :  660,000 kilometers (400,000 miles) Time :  5:05 am PST This Voyager 1 picture of Mimas shows a large impact structure at 110 degrees W Long., located on that face of the moon which leads Mimas in its orbit.  The feature, about 130 kilometers in diameter (80 miles), is more than 1/4 the diameter of the entire moon.  This is a particularly interesting feature in view of its large diameter compared with the size of the satellite, and may have the largest crater diameter/satillite diameter ratio in the solar system.  The crater has a raised rim and central peak, typical of large impact structures on terrestrial planets.  Additional smaller craters, 15-45 kilometers in diameter, can be seen scattered across the surface, particularly alon the terminator.  Mimas is one of the smaller Saturnian satellites with a low density implying its chief component is ice. ARC-1980-A80-7034

P-29511 BW Range: 130,000 kilometers (80,000 miles) This clear-filter, narrow-angle picture is part of the high-resolution Voyager 2 imaging sequence of Ariel, a moon of Uranus about 1,300 kilometers (800 miles) in diameter. The complexity of Ariels' surface indicates that a variety of geologic processes have occured. The numerous craters, for example, are indications of an old surface bombarded by meteroids over a long periond. Also conspicuous at this resolution, about 2.4 km (1.5 mi), are linear grooves (evidence of tectonic activity that has broken up the surface) and smooth patches (indicative of deposition of material).

P-34540 Range: 37.3 million kilometers (23.6 million miles) This image captured by the Voyager 2 spacecraft was used to confirm the discovery of three new satellites orbiting Neptune. The 46-second exposure was taken with the narrow angle camera and shows the large globe of the planet to be severely overexposed and almost pure white in appearance. The image has been computer-processed to accentuate the new moons, which otherwise would be hard to distinguish from background noise. The satellite 1989N1, at right in this frame, was discovered by Voyager 2 in early July 1989. The new satellites confirmed later are 1989N2, 1989N3 and 1989N4. Each of the moons appears as a small streak, an effect caused by movement of the spacecraft during the long exposure. The new moons occupy nearly circular and equatorial orbits ranging from about 27,300 to 48,300 kilometers (17,000 to 30,000 miles) from Neptunes's cloud tops, and are estimated to range in diameter from about 100 to 200 kilometers (about 60 to 125 miles).

KENNEDY SPACE CENTER, FLA. -- The NASA Comet Nucleus Tour (CONTOUR) spacecraft arrived at KSC on April 24 and was transported to the Spacecraft Assembly and Encapsulation Facility-2 (SAEF-2) to begin final preparations for launch.  CONTOUR will provide the first detailed look into the heart of a comet - the nucleus. The spacecraft will fly as close as 60 miles (100 kilometers) to at least two comets, Encke and Schwassmann-Wachmann 3, taking the sharpest pictures yet of the nucleus while analyzing the gas and dust that surround these rocky, icy building blocks of the solar system.  The Applied Physics Laboratory of Johns Hopkins University, Baltimore, Md., built CONTOUR and will also be in control of the spacecraft after launch, scheduled for July 1, 2002, from LC 17A at Cape Canaveral Air Force Station KSC-02pd0571

Range : 7 million kilometers (5 million miles) Callisto is Jupiter's outermost Galilean satellites and darkest of  the four(but almost twice as bright as Earth's Moon).  Mottled appearance from bright and dark patches.  Bright spots seem like rayed or bright halved craters seen on our Moon.  This face is always turned toward Jupiter.  Photo taken through violet filter.  Ganymede is slightly larger than Mercury but much less dense (twice the density of water).  Its surface brightness is 4 times of Earth's Moon.  Mare regions (dark features) are like the Moon's but have twice the brightness, and believed to be unlikely of rock or lava as the Moon's are.  It's north pole seems covered with brighter material and may be water frost.  Scattered brighter spots may be related to impact craters or source of fresh ice. ARC-1979-A79-7020

P-21747 C Range: 2,200,000 miles This image shows a region of the Jovian atmosphere from approximately 25° N to the equatorial region. The north temperate jet, at approximately 23° N, where the wind speed is about 150 meters per second, is seen as a dark brown line from the left-hand edge to the right-hand corner of the picture. The wispy clouds of the north equatorial belt appear as shades of brown. The lower right-hand corner of the image shows the brighter (white) clouds of the equatorial region. A small blue area is apparent near the lower edge, which corresponds to a region free of the upper clouds, where it is possible to penetrate to cloud layers approximately 60 kilometers below the visible surface.

P-34692 Range :  500 km. ( 300 miles ) Smallest Resolvable Feature :  900 m. or 2,700 ft. Part of Triton's complex geological history canbe seen in this image, shot by Voyager 2. Part of a sequence,  it shows a surface dominated by many roughly circular, polygonal, and arcuate features between 30 and 50 km (18 and 30 miles ) across. Some resemble degraded impact craters of Mars, while others resemble the 'palimpsest' features of Jupiter's satellite Ganymede. Peculiar intersecting, double ridged lines are 15 to 20 km. or 9 to 12 miles wide and hundreds of kilometers long.  Theyresemble some deformational belts of Ganymede. Patches of plainsforming material tend to occur in local depressions. The geologic features of Triton and spectroscopic information indicates that the surface  of Triton is underlain by a mixture of ices. ARC-1989-A89-7030

P-34718 Range: 210,000 kilometers (128,000 miles) This natural color image of the limb of Triton shows the largest surface features at about 3 miles across. The picture is a composite of images taken through the violet, green and clear filters and shows a geologic boundary between a rough, pitted surface to the right and a smoother surface to the left. The change between surface types is gradual. The image also shows a color boundary between pinkish material in the upper part of the image and whiter material in the lower part. The geologic and color boundaries are not the same. That implies that whatever supplies the color is a very thin coating over a different underlying material in which the geologic boundary occurs. The colored coating may be a seasonal frost composed of compounds volatile enough to be sublimated at the very low temperatures (40 K to 50 K or -387.4 F to -369.4 F) prevailing near Triton's surface. Possible compositions of the frost layer include methane (which turns red when irradiated), carbon monoxide or nitrogen. The color in this image is somewhat exaggerated: Triton is primarily a white object with a pinkish cast in some areas. ARC-1989-AC89-7052

This image is the first full picture showing both asteroid 243 Ida and its newly discovered moon to be transmitted to Earth from NASA's Galileo spacecraft--the first conclusive evidence that natural satellites of asteroids exist.  Ida is the large object to the left, about 56 kilometers (35 miles long).  Ida's natural satellite is the small object to the right.  This portrait was taken by Galileo's charge-coupled device (CCD) camera on August 28, 1993, about 14 minutes before the spacecraft's closest approach to the asteriod, from a range of 10,870 kilometers (6,755 miles).  Ida is a heavily cratered, irregularly shaped asteroid in the main asteroid belt between Mars and Jupiter-- the 243rd asteroid to be discovered since the first one was found at the beginning of the 19th century.  It is a member of a group of asteroids called the Koronis family.  The small satellite, which is about 1.5 kilometers (1 mile) across in this view, has yet to be given a name by astronomers.  It has been provisionally designated '1993 (243) 1' by the International Astronomical Union.  (The numbers denote the year the picture was taken, the asteroid number and the fact that it is the first moon of Ida to be found.)  ALthough the satellite appears to be 'next' to Ida it is actually slightly in the foreground, closer to the spacecraft than Ida.  Combining this image with data from Galileo's near-infrared mapping spectrometer, the science team estimates that the object is about 100 kilometers (60 miles) away from the center of Ida.  This image is one of a six-frame series taken through different color filters, this one in green.  The spatial resolution in this image is about 100 meters (330 feet) per pixel.  The Galileo spacecraft flew past Ida en route to its final destination, Jupiter, where it will go into orbit in December 1995.  The Jet Propulsion Laboratory manages the galileo Project for NASA's Office of Space Science. (JPL ref. No. P-43731) ARC-1994-A91-2018

A Shuttle Training Aircraft (STA) taxis into the parking area of KSC's Shuttle Landing Facility. The STA is a modified Grumman American Aviation-built Gulfstream II executive jet that was modified to simulate an orbiter's cockpit, motion and visual cues, and handling qualities. It is used by Shuttle flight crews to practice landing the orbiter. In flight, the STA duplicates the orbiter's atmospheric descent trajectory from approximately 35,000 feet altitude to landing on a runway. The orbiter differs in at least one major aspect from conventional aircraft; it is unpowered during re-entry and landing so its high-speed glide must be perfectly executed the first time there is no go-around capability. The orbiter touchdown speed is 213 to 226 miles (343 to 364 kilometers) per hour. There are two STAs, based in Houston KSC00pp0604

ISS009-E-18679 (17 August 2004) --- Ural River Delta, Kazakhstan is featured in this image photographed by an Expedition 9 crewmember on the International Space Station (ISS). The Ural River is one of two major rivers (the other river is the Volga) that empty into the northern coast of the Caspian Sea, creating extensive wetlands. This image shows details of the Ural's tree-like (or “digitate”) delta. According to NASA scientists studying the Space Station imagery, this type of delta forms when wave action is low and sediment content in the river is high. New distributary channels form in the delta when the river breaches natural levees formed by sediment deposition.  The dark regions running along the coast are the wetlands that support high biodiversity due to the unique environment and relative isolation of the Caspian Sea. The coastal wetlands are especially important to migrating birds as an important stop-over along the Asian flyway. The Ural River's trek to the Caspian is long — roughly 2400 kilometers (1500 miles) from the Ural Mountains in Russia south to empty into the northern Caspian Sea in Kazakhstan. Although the current sea level of the Caspian is more than 26 meters below global mean sea level the water levels have risen roughly 2 meters since 1980. This has lead to flooding of much of the coastal region, including the Ural delta, and endangers these coastal wetland environments. The coastal flooding has also impacted the oil exploration infrastructure bordering the Caspian coastline, scientists report. iss009e18679

ISS031-E-116058 (13 June 2012) --- Polar mesospheric clouds in the Northern Hemisphere are featured in this image photographed by an Expedition 31 crew member on the International Space Station. In both the Northern and Southern Hemisphere, during their respective late spring and early summer seasons, polar mesospheric clouds are at the peak of their visibility. Visible from the ground during twilight, aircraft in flight, and the International Space Station, they typically appear as delicate shining threads against the darkness of space?hence their other name of noctilucent or ?night-shining? clouds. On the same day this image was taken from the space station while it was passing over the night-darkened Tibetan Plateau, polar mesospheric clouds were also visible to aircraft flying above Canada. In addition to this still image, the space station crew took a time-lapse image sequence of polar mesospheric clouds several days earlier (June 5, 2012) while passing over western Asia; this is first such sequence of images of the phenomena taken from orbit. Polar mesospheric clouds form between 76-85 kilometers above the Earth?s surface, when there is sufficient water vapor at these high altitudes to freeze into ice crystals. The clouds are illuminated by the setting sun while the ground surface below is in darkness, lending them their night-shining properties. In addition to the illuminated tracery of polar mesospheric clouds trending across the center of the image, lower layers of the atmosphere are also illuminated; the lowest layer of the atmosphere, the stratosphere, is indicated by dim orange and red tones. While the exact cause of formation of polar mesospheric clouds is still debated?dust from meteors, global warming, and rocket exhaust have all been suggested as contributing factors?recent research suggests that changes in atmospheric gas composition or temperature has caused the clouds to become brighter over time. iss031e116058

CAPE CANAVERAL, Fla. – A “supermoon” begins to rise through the clouds near the 525-foot-tall Vehicle Assembly Building in Launch Complex 39 at NASA’s Kennedy Space Center in Florida.    The scientific term for the supermoon phenomenon is "perigee moon." Full moons vary in size because of the oval shape of the moon's orbit. The moon follows an elliptical path around Earth with one side about 50,000 kilometers closer than the other. Full moons that occur on the perigee side of the moon's orbit seem extra big and bright.

Photo by Voyager 1 Jupiter's satellite Io poses before the giant planet in this photo returned Jan 17, 1979 from a distance of 29 million miles (47 million kilometers). The satellite's shadow can be seen falling on the face of Jupiter at left. Io is traveling from left to right in its one-and-three-quarter-day orbit around Jupiter. Even from this great distance the image of Io shows dark poles and bright equatorial region. Voyager 1 will make its closest approach to Jupiter  174, 000 miles (280,000 kilometer) on March 5. It will then continue to Saturn in November 1980. This color photo was assembled at Jet Propulsion Laboratory's Image Processing Lab from three black and white images taken through filters. The Voyagers are managed for NASA's Office of Space Science by Jet Propulsion Laboratory. (JPL Ref: P-20946C) ARC-1979-AC79-0143-4

Range :  1.2 million kilometers (750,000 miles) This picture of Io is one of the last sequence of 'volcano watch' pictures planned as a time lapse study of the nearest of Jupiter's Galilean satellites.  The sunlit crescent of Io is seen at the left, and the night side illuminated by light reflected from Jupiter can also be seen.  Three volcanic eruption plumes are visible on the limb.  All three were previously seen by Voyager 1.  On the bright limb Plume 5 (upper) and Plume 6 (lower) are about 100 km high, while Plume 2 on the dark limb is about 185 km high and 325 km wide.  The dimensions of Plume 2 are about 1 1/2 times greater than during the Boyager 1 encounter, indicating that the intensity of the eruptions has increased during the four-month time interval between the Boyager encounters.  The three volcanic eruptions and at least three others have apparently been active at roughly the same intesity or greater for a period of at least four months. ARC-1979-A79-7099

P-21760 C This color image of the Jovian moon Europa, which is the size of our moon, is thought to have a crust of ice perhaps 100 kilometers thick which overlies the silicate crust. The complex array of streaks indicate that the crust has been fractured and filled by materials from the interior. The lack of relief, any visible mountains or craters, on its bright limb is consistent with a thick ice crust. In contrast to its icy neighbors, Ganymede and Callisto, Europa has very few impact craters. One possible candidate is the small feature near the center of this image with radiating rays and a bright circular interior. The relative absence of features and low topography suggests the crust is young and warm a few kilometers below the surface. The tidal heating process suggested for Io also may be heating Europa's interior at a lower rate. ARC-1979-AC79-7088
