P-29502C Range: 1.04 million kilometers (650,000 miles) This color photo of Umbriel, the darkest of Uranus' five large moons was synthesized from frames exposed with the Voyager narrow-angle camera's violet and clear filters and has a resolution of 19 km (12 mi.). Umbriel is characterized by the darkest surface and smallest brightness variations of any of the large satellites of Uranus. As seen here, the surface is also generally gray and colorless. Nevertheless, at this resolution, considerable topographic detail is revealed, showing that Umbriel's surface is covered by impact craters. The brightest spot (shown at top near the equator at approxiamately 270 ° longitude) appears as a bright ring. Its geological significance is not yet understood. Umbriel has a diameter of about 1,200 km (750 miles) and orbits 267,000 km (166,000 mi) from Uranus' center. The satellite's name, from Alexander Pope's 'Rape of the Lock,' means 'dark angel'.

VANDENBERG AIR FORCE BASE, Calif. -- The Aquarius/SAC-D spacecraft is offloaded from a U.S. Air Force C-17 transport at Vandenberg Air Force Base in California. The aircraft traveled from Campos, Brazil. Following final tests, the spacecraft will be integrated to a United Launch Alliance Delta II rocket in preparation for the targeted June launch to low Earth orbit.        Aquarius, the NASA-built primary instrument on the SAC-D spacecraft, will map global changes in salinity at the ocean's surface. Salinity is a key measurement for understanding how changes in rainfall, evaporation and the melting of freezing of ice influence ocean circulation and are linked to variations in Earth's climate. The three-year mission will provide new insights into how variations in ocean surface salinity relate to these fundamental climate processes. Photo credit: VAFB/30th Space Wing KSC-2011-2628

CAPE CANAVERAL, Fla. – – Sami Asmar, GRAIL deputy project scientist, NASA’s Jet Propulsion Laboratory, participates in the Gravity Recovery and Interior Laboratory (GRAIL) mission science briefing in the NASA Press Site auditorium at NASA's Kennedy Space Center in Florida. GRAIL is scheduled to launch Sept. 8 aboard a United Launch Alliance Delta II Heavy rocket from Cape Canaveral Air Force Station in Florida.    GRAIL will fly twin spacecraft in tandem around the moon to precisely measure and map variations in the moon's gravitational field. The mission will provide the most accurate global gravity field to date for any planet, including Earth. This detailed information will reveal differences in the density of the moon's crust and mantle and will help answer fundamental questions about the moon's internal structure, thermal evolution, and history of collisions with asteroids. The aim is to map the moon's gravity field so completely that future moon vehicles can safely navigate anywhere on the moon’s surface. For more information, visit http://www.nasa.gov/grail.

CAPE CANAVERAL, Fla. – – Leesa Hubbard, teacher in residence, Sally Ride Science, San Diego, participates in the Gravity Recovery and Interior Laboratory (GRAIL) mission science briefing in the NASA Press Site auditorium at NASA's Kennedy Space Center in Florida. GRAIL is scheduled to launch Sept. 8 aboard a United Launch Alliance Delta II Heavy rocket from Cape Canaveral Air Force Station in Florida.    GRAIL will fly twin spacecraft in tandem around the moon to precisely measure and map variations in the moon's gravitational field. The mission will provide the most accurate global gravity field to date for any planet, including Earth. This detailed information will reveal differences in the density of the moon's crust and mantle and will help answer fundamental questions about the moon's internal structure, thermal evolution, and history of collisions with asteroids. The aim is to map the moon's gravity field so completely that future moon vehicles can safely navigate anywhere on the moon’s surface. For more information, visit http://www.nasa.gov/grail.

CAPE CANAVERAL, Fla. – Plumes of smoke surround Space Launch Complex 17B on Cape Canaveral Air Force Station in Florida as a United Launch Alliance Delta II Heavy rocket lofts NASA’s Gravity Recovery and Interior Laboratory (GRAIL) mission into space. Liftoff was at 9:08:52 a.m. EDT Sept.10. GRAIL-A will separate from the second stage of the rocket at about one hour, 21 minutes after liftoff, followed by GRAIL-B at 90 minutes after launch. The spacecraft are embarking on a three-month journey to reach the moon.    GRAIL will fly twin spacecraft in tandem around the moon to precisely measure and map variations in the moon's gravitational field. The mission will provide the most accurate global gravity field to date for any planet, including Earth. This detailed information will reveal differences in the density of the moon's crust and mantle and will help answer fundamental questions about the moon's internal structure, thermal evolution, and history of collisions with asteroids. The aim is to map the moon's gravity field so completely that future moon vehicles can safely navigate anywhere on the moon’s surface. For more information, visit http://www.nasa.gov/grail.

Range :  1,094,666 km (677,000 mi.) This false color picture of Callisto was taken by Voyager 2 and is centered on 11 degrees N and 171 degrees W.  This rendition uses an ultraviolet image for the blue component.  Because the surface displays regional contrast in UV, variations in surface materials are apparent.  Notice in particular the dark blue haloes which surround bright craters in the eastern hemisphere.  The surface of Callisto is the most heavily cratered of the Galilean satellites and resembles ancient heavily cratered terrains on the moon, Mercury and Mars.  The bright areas are ejecta thrown out by relatively young impact craters.  A large ringed structure, probably an impact basin, is shown in the upper left part of the picture.  The color version of this picture was constructed by compositing black and white images taken through the ultraviolet, clear and orange filters. ARC-1979-AC79-7104

VANDENBERG AIR FORCE BASE, Calif. --  A Delta II rocket appears to erupt from the undulating clouds of smoke below as it launches with the joint NASA/French Space Agency oceanography satellite Jason 1 and Thermosphere Ionosphere Mesosphere Energetics and Dynamics satellite aboard.  Liftoff from Launch Complex 2W occurred at 7:07 a.m. PST (10:07 a.m. EST or 15:07 GMT).  Jason 1 joins the orbiting Topex/Poseidon satellite to continue observations of the global climate interaction occurring between the sea and the atmosphere as a result of stored solar energy.  Instruments on Jason 1 will map variations in ocean surface topography to monitor world ocean circulation, study interactions of the oceans and atmosphere, improve climate predictions and observe events like El Nino.  The mission is expected to last three years.  The TIMED satellite will study a little-known region above the atmosphere, some 40 to 110 miles from the Earth's surface. Studying this region has been nearly impossible until now because conventional airplanes and balloons cannot reach this high altitude, and it is too low for direct satellite measurements KSC01pd1821

CAPE CANAVERAL, Fla. – At ignition, flames from the engines begin liftoff of the United Launch Alliance Delta II Heavy rocket carrying NASA’s twin Gravity Recovery and Interior Laboratory (GRAIL) mission off Space Launch Complex 17B on Cape Canaveral Air Force Station. The spacecraft launched at 9:08:52 a.m. EDT Sept. 10. GRAIL-A will separate from the second stage of the rocket at about one hour, 21 minutes after liftoff, followed by GRAIL-B at 90 minutes after launch. The spacecraft are embarking on a three-month journey to reach the moon.    GRAIL will fly twin spacecraft in tandem around the moon to precisely measure and map variations in the moon's gravitational field. The mission will provide the most accurate global gravity field to date for any planet, including Earth. This detailed information will reveal differences in the density of the moon's crust and mantle and will help answer fundamental questions about the moon's internal structure, thermal evolution, and history of collisions with asteroids. The aim is to map the moon's gravity field so completely that future moon vehicles can safely navigate anywhere on the moon’s surface. For more information, visit http://www.nasa.gov/grail.

KENNEDY SPACE CENTER,FLA. -- Inside the Payload Changeout Room (PCR) in the Rotating Service Structure (RSS) at Launch Pad 39-B, technicians in clean suits and tethers prepare to move the payloads for mission STS-95 through the open doors of the payload bay (left) of Space Shuttle Discovery. At the top of the RSS is the Spacehab module; below it are the Spartan solar-observing deployable spacecraft, the Hubble Space Telescope Orbiting Systems Test Platform (HOST), and the International Extreme Ultraviolet Hitchhiker (IEH-3). The PCR is an environmentally controlled facility with seals around the mating surface that fit against the orbiter or payload canister and permit the payload bay or canister doors to be opened and cargo removed without exposing it to outside air and contaminants. Payloads are installed vertically in the orbiter using the extendable payload ground handling mechanism. Fixed and extendable work platforms provide work access in the PCR. The SPACEHAB single module involves experiments on space flight and the aging process. Spartan is a solar physics spacecraft designed to perform remote sensing of the hot outer layers of the sun's atmosphere or corona. HOST carries four experiments to validate components planned for installation during the third Hubble Space Telescope servicing mission and to evaluate new technologies in an Earth-orbiting environment. IEH-3 comprises several experiments that will study the Jovian planetary system, hot stars, planetary and reflection nebulae, other stellar objects and their environments through remote observation of EUV/FUV emissions; study spacecraft interactions, Shuttle glow, thruster firings, and contamination; and measure the solar constant and identify variations in the value during a solar cycle. Mission STS-95 is scheduled to launch Oct. 29, 1998 KSC-98pc1184

VANDENBERG AIR FORCE BASE, Calif.. --   A Delta rocket leaps off Launch Complex 2W carrying the joint NASA/French Space Agency oceanography satellite Jason 1 and Thermosphere Ionosphere Mesosphere Energetics and Dynamics satellite aboard.   Liftoff occurred at 7:07 a.m. PST (10:07 a.m. EST or 15:07 GMT).  Jason 1 joins the orbiting Topex/Poseidon satellite to continue observations of the global climate interaction occurring between the sea and the atmosphere as a result of stored solar energy.  Instruments on Jason 1 will map variations in ocean surface topography to monitor world ocean circulation, study interactions of the oceans and atmosphere, improve climate predictions and observe events like El Nino.  The mission is expected to last three years.  The TIMED satellite will study a little-known region above the atmosphere, some 40 to 110 miles from the Earth's surface. Studying this region has been nearly impossible until now because conventional airplanes and balloons cannot reach this high altitude, and it is too low for direct satellite measurements KSC01pd1822
