Description In this 1960 photograph, the seven original Mercury astronauts participate in U.S. Air Force survival training exercises at Stead Air Force Base in Nevada. Pictured from left to right are: L. Gordon Cooper, M. Scott Carpenter, John Glenn, Alan Shepard, Virgil I. Grissom, Walter Schirra and Donald K. Slayton. Portions of their clothing have been fashioned from parachute material, and all have grown beards from their time in the wilderness. The purpose of this training was to prepare astronauts in the event of an emergency or faulty landing in a remote area. Forty-five years ago today on May 24, 1962, Scott Carpenter went on to fly the second American manned orbital flight. He piloted his Aurora 7 spacecraft through three revolutions of the Earth, reaching a maximum altitude of 164 miles. The spacecraft landed in the Atlantic Ocean about 1,000 miles, about 1,609 kilometers, southeast of Cape Canaveral after the 4 hour, 54 minute flight. Image credit: NASA

Description This spaceborne radar image shows the famous "hook" of Cape Cod, Massachusetts. The Cape, which juts out into the Atlantic Ocean about 100 kilometers (62 miles) southeast of Boston, actually consists of sandy debris left behind by the great continental ice sheets when they last retreated from southern New England about 20,000 years ago. Today's landscape consists of sandy forests, fields of scrub oak and other bushes and grasses, salt marshes, freshwater ponds, as well as the famous beaches and sand dunes. In this image, thickly forested areas appear green, marshes are dark blue, ponds and sandy areas are black, and developed areas are mostly pink. The dark L-shape in the lower center is the airport runways in Hyannis, the Cape's largest town. The dark X-shape left of the center is Otis Air Force Base. The Cape Cod Canal, above and left of center, connects Buzzards Bay on the left with Cape Cod Bay on the right. The northern tip of the island of Martha's Vineyard is seen in the lower left. The tip of the Cape, in the upper right, includes the community of Provincetown, which appears pink, and the protected National Seashore areas of sand dunes that parallel the Atlantic coast east of Provincetown. Scientists are using radar images like this one to study delicate coastal environments and the effects of human activities on the ecosystem and landscape. This image was acquired by Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR-C/X-SAR) onboard the space shuttle Endeavour on April 15, 1994. The image is 81.7 kilometers by 43.1 kilometers (50.7 miles by 26.7 miles) and is centered at 41.8 degrees north latitude, 70.3 degrees west longitude. North is toward the upper right. The colors are assigned to different radar frequencies and polarizations of the radar as follows: red is L-band, horizontally transmitted and received, green is C- band, horizontally transmitted, vertically received, and blue is C-band, horizontally transmitted and received. SIR-C/X-SAR, a joint mission of the German, Italian and United States space agencies, is part of NASA's Mission to Planet Earth program. #####

Description This image was produced during radar observations taken by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar as it flew over the Gulf Stream, Florida, and past the Atlantic Ocean on October 7, 1994. The data were produced using the X-band radar frequency. Knowing ahead of time that this region would be included in a regularly scheduled radar pass, the Kennedy Space Center team, who assembled and integrated the SIR-C/X-SAR equipment with the Spacelab pallet system, designed a set of radar reflectors from common construction materials and formed the letters "KSC" on the ground adjacent to the main headquarters building at the entrance to the Cape Canaveral launch facility. The point of light formed by the bright return from these reflectors are visible in the image. Other more diffuse bright spots are reflections from building faces, roofs and other large structures at the Kennedy Space Center complex. This frame covers an area of approximately 6 kilometers by 8 kilometers (4 miles by 5 miles), which was just a small portion of the data taken on this particular pass. ----- Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth. The radars illuminate Earth with microwaves, allowing detailed observations at any time, regardless of weather or sunlight conditions. SIR-C/X-SAR uses three microwave wavelengths: L-band (24 cm), C-band (6 cm) and X-band (3 cm). The multi-frequency data will be used by the international scientific community to better understand the global environment and how it is changing. The SIR-C/X-SAR data, complemented by aircraft and ground studies, will give scientists clearer insights into those environmental changes which are caused by nature and those changes which are induced by human activity. SIR-C was developed by NASA's Jet Propulsion Laboratory. X-SAR was developed by the Dornier and Alenia Spazio companies for the German space agency, Deutsche Agentur fuer Raumfahrtangelegenheiten (DARA), and the Italian space agency, Agenzia Spaziale Italiana (ASI), with the Deutsche Forschungsanstalt fuer Luft und Raumfahrt e.V.(DLR), the major partner in science, operations and data processing of X-SAR. #####

Description This is an X-band Synthetic Aperture Radar image spanning an area of about 20 kilometers by 40 kilometers (12 miles by 25 miles) of the Kennedy Space Center, Florida. At the top right are cloud-like structures which indicate rain. X-SAR is able to image heavy rainfall. The Atlantic Ocean is at the upper right. The shuttle landing strip is seen at the top left of the image. The Vertical Assembly Building, the Orbiter Processing Facility and other associated buildings are seen as a white area to the right and just above the end of the shuttle strip. The shuttle launch pads are the two white areas near the top center of the image. The Banana River shows up as a large black area running north to south to the right of the image. The Indian River is on the left side of the image. Just above the image center is a cluster of white spots which are the major buildings of the Kennedy Space Center industrial area. This was the location of the reflector array that was constructed to form the letters "KSC" by the KSC payload team. The data for these KSC images were taken on orbit 81 of the space shuttle Endeavour on the fourth day of the SIR-C/X-SAR mission. ----- Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth.

Description This is radar image of the New York city metropolitan area. The island of Manhattan appears in the center of the image. The green-colored rectangle on Manhattan is Central Park. This image was acquired by the Spaceborne Imaging Radar-C/X- band Synthetic Aperture Radar (SIR-C/ X-SAR) aboard the space shuttle Endeavour on October 10, 1994. North is toward the upper right. The area shown is 75.0 kilometers by 48.8 kilometers (46.5 miles by 30.2 miles). The image is centered at 40.7 degrees north latitude and 73.8 degrees west longitude. In general, light blue areas correspond to dense urban development, green areas to moderately vegetated zones and black areas to bodies of water. The Hudson River is the black strip that runs from the left edge to the upper right corner of the image. It separates New Jersey, in the upper left of the image, from New York. The Atlantic Ocean is at the bottom of the image where two barrier islands along the southern shore of Long Island are also visible. John F. Kennedy International Airport is visible above these islands. Long Island Sound, separating Long Island from Connecticut, is the dark area right of the center of the image. Many bridges are visible in the image, including the Verrazano Narrows, George Washington and Brooklyn bridges. The radar illumination is from the left of the image, this causes some urban zones to appear red because the streets are at a perpendicular angle to the radar pulse. The colors in this image were obtained using the following radar channels: red represents the L-band (horizontally transmitted and received), green represents the L-band (horizontally transmitted, vertically received), blue represents the C-band (horizontally transmitted, vertically received). Radar images like this one could be used as a tool for city planners and resource managers to map and monitor land use patterns. The radar imaging systems can clearly detect the variety of landscapes in the area, as well as the density of urban development.

Pale Blue Orb (1)
Description Pale Blue Orb
Full Description Not since NASA's Voyager 1 spacecraft saw our home as a pale blue dot from beyond the orbit of Neptune has Earth been imaged in color from the outer solar system. Now, Cassini casts powerful eyes on our home planet, and captures Earth, a pale blue orb -- and a faint suggestion of our moon -- among the glories of the Saturn system. Earth is captured here in a natural color portrait made possible by the passing of Saturn directly in front of the sun from Cassini's point of view. At the distance of Saturn's orbit, Earth is too narrowly separated from the sun for the spacecraft to safely point its cameras and other instruments toward its birthplace without protection from the sun's glare. The Earth-and-moon system is visible as a bright blue point on the right side of the image above center. Here, Cassini is looking down on the Atlantic Ocean and the western coast of north Africa. The phase angle of Earth, seen from Cassini is about 30 degrees. A magnified view of the image taken through the clear filter (monochrome) shows the moon as a dim protrusion to the upper left of Earth. Seen from the outer solar system through Cassini's cameras, the entire expanse of direct human experience, so far, is nothing more than a few pixels across. Earth no longer holds the distinction of being our solar system's only "water world," as several other bodies suggest the possibility that they too harbor liquid water beneath their surfaces. The Saturnian moon, Enceladus, is among them, and is also captured on the left in this image (see inset), with its plume of water ice particles and swathed in the blue E ring which it creates. Delicate fingers of material extend from the active moon into the E ring. See Ghostly Fingers of Enceladus, for a more detailed view of these newly-revealed features. The narrow tenuous G ring and the main rings are seen at the right. The view looks down from about 15 degrees above the un-illuminated side of the rings. Images taken using red, green and blue spectral filters were combined to create this view. The image was taken by the Cassini spacecraft wide-angle camera on Sept. 15, 2006, at a distance of approximately 2.1 million kilometers (1.3 million miles) from Saturn and at a sun-Saturn-spacecraft angle of almost 179 degrees. Image scale is 129 kilometers (80 miles) per pixel. At this time, Cassini was nearly 1.5 billion kilometers (930 million miles) from Earth. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.

Title Global Large-scale Precipitation during Hurricane Frances (WMS)
Abstract Water vapor is a small but significant constituent of the atmosphere, warming the planet due to the greenhouse effect and condensing to form clouds. As moisture-laden air rises, the relative humidity increases until it saturates the air, at which time precipitation occurs. If the uplift of air is due to large-scale atmospheric motion, then the precipitation is called large-scale, or dynamic. This animation shows the large-scale precipitation for the whole globe from September 1, 2004, through September 5, 2004, during the period of Hurricane Frances in the western Atlantic Ocean and Typhoon Songda in the western Pacific Ocean. Large-scale precipitation tends to be continuous and to come from decks of stratus clouds rather than from thunderstorms.

Title Sequence of Clouds, Snow Cover, Sea Ice, Sea Surface Temperature and Biosphere
Abstract This animation is part of an NSF-funded, international project, Exploring Time. The two-hour television special, broadcast on the Discovery Channel in the spring of 2007, explores how the world changes over different timescales ... from billionths of seconds to billions of years. This animation portrays a variety of remotely sensed data elements at different temporal resolutions. Initially, the animation shows cloud cover in motion over North America in half-hour increments from Nov. 26 to Dec. 7, 2005. The temporal pace quickens to show a 5-day moving average of daily MODIS snow cover along with daily AMSR-E sea ice from Dec. 7, 2005 to Mar. 15, 2006. As the view swings south over the Gulf of Mexico, the AMSR-E Sea Surface Temperature reveals warming ocean temperatures from March through August, 2006. As it passes over the Atlantic Ocean, the biosphere fades into view, showing both chlorophyll concentration in the ocean along with Normalized Difference Vegetation Index over the land areas. The biosphere animates over time while the view pans over northern Africa and Europe, showing data collected from September 2002 through February 2006. This program was also broadcast in Japan through a partnership with the NHK international broadcasting service and in France through a partnership with the ARTE television network.

Title Rainfall Accumulation from Hurricane Isabel (WMS)
Abstract Hurricane Isabel generated large amounts of rain over the Atlantic ocean as it approached East coast of the United States in September 2003. In fact, unlike many hurricanes, most of the Isabel's rainfall did not occur over land, flooding on land was caused mainly by storm surge. This animation shows accumulation of rainfall from the hurricane--each frame shows the total amount of rain since the start of the measurement period. Rain from other sources has been masked out, so the hurricane track is clearly visible as the storm moves across the Atlantic.

Title Rainfall Accumulation from Hurricane Isabel (WMS)
Abstract Hurricane Isabel generated large amounts of rain over the Atlantic ocean as it approached East coast of the United States in September 2003. In fact, unlike many hurricanes, most of the Isabel's rainfall did not occur over land, flooding on land was caused mainly by storm surge. This animation shows accumulation of rainfall from the hurricane--each frame shows the total amount of rain since the start of the measurement period. Rain from other sources has been masked out, so the hurricane track is clearly visible as the storm moves across the Atlantic.

Title Global Cloud Cover during Hurricane Frances (WMS)
Abstract Water vapor is a small but significant constituent of the atmosphere, warming the planet due to the greenhouse effect and condensing to form clouds which both warm and cool the Earth in different circumstances. Warm, moisture-laden air moving out from the tropics brings clouds and rainfall to the temperate zones. This animation shows the cloud cover for the whole globe from September 1, 2004, through September 5, 2004, during the period of Hurricane Frances in the western Atlantic Ocean and Typhoon Songda in the western Pacific Ocean. The cloud cover in any region significantly affects the energy balance since sunlight reflected from the clouds is not available to heat the surface. The motion of clouds in this animation clearly indicates the speed and direction of winds around the globe.

This animation shows the atmospheric water vapor for the whole globe from September 1, 2004, through September 5, 2004, during the period of Hurricane Frances in the western Atlantic Ocean and Typhoon Songda in the western Pacific Ocean. The band of water vapor over the tropics is the intertropical convergence zone, where converging trade winds and high temperatures force large amounts of water high into the atmosphere. Both Hurricane Frances and Typhoon Songda exhibit significant spiral bands of high water vapor.

Title Global Convective Precipitation during Hurricane Frances (WMS)
Abstract Water vapor is a small but significant constituent of the atmosphere, warming the planet due to the greenhouse effect and condensing to form clouds. As moisture-laden air rises, the relative humidity increases until it saturates the air, at which time precipitation occurs. If the uplift of air is due to strong updrafts and unstable air systems, as in thunderstorms, then the precipitation is called convective. This animation shows the convective precipitation for the whole globe from September 1, 2004, through September 5, 2004, during the period of Hurricane Frances in the western Atlantic Ocean and Typhoon Songda in the western Pacific Ocean. Convective precipitation is more intense but less long-lasting than large-scale precipitation.

Title Global Sea Surface Temperature from June, 2002 to September, 2003 (WMS)
Abstract The temperature of the surface of the world's oceans provides a clear indication of the state of the Earth's climate and weather. The AMSR-E instrument on the Aqua satellite measures the temperature of the top 1 millimeter of the ocean every day, even through the clouds. In this visualization sequence covering the period from June, 2002, to September, 2003, the most obvious effects are the north-south movement of warm regions across the equator due to the seasonal movement of the sun and the seasonal advance and retreat of the sea ice near the North and South poles. It is also possible to see the Gulf Stream, the warm river of water that parallels the east coast of the United States before heading towards northern Europe, in this data. Around January 1, 2003, a cooler than normal region of the ocean appears just to the west of Peru as part of a La Nina and flows westward, driven by the trade winds. The waves that appear on the edges of this cooler area are called tropical instability waves and can also be seen in the equatorial Atlantic Ocean about the same time.

Title North Atlantic Ocean Current Velocity
Abstract Three-dimensional General Circulation Models divide the ocean into a rectangular grid with layered vertical columns. This North Atlantic model uses a 1/6 degree grid with 37 layers. It captured 30 years of velocity, sea-surface temperature, and salinity. The model realistically separates the Gulf Stream from the Florida coast. A feature as small as the Gulf Stream had not appeared in lower-resolution models.

Title Global High Altitude Wind Speed during Hurricane Frances (WMS)
Abstract The Earth's atmosphere exerts pressure based on the weight of the air above. Differences in pressure from place-to-place cause winds to try to flow from high pressure to low pressure regions to even out the differences, but the Earth's rotation and wind friction with the surface act to slow or divert the winds. This animation shows the high altitude wind speeds for the whole globe from September 1, 2004, through September 5, 2004, during the period of Hurricane Frances in the western Atlantic Ocean and Typhoon Songda in the western Pacific Ocean. At high altitudes, the difference between between high pressures from warm tropical air and low pressures from cold polar air try to force air from the tropics toward the poles, but the Earth's rotation diverts this flow to the east, resulting in the high velocity west-to-east jet stream flows at mid-latitudes. The circular flows from Frances and Songda can barely be seen at this altitude.

Title Global 300 hPa Geopotential Height during Hurricane Frances (WMS)
Abstract The Earth's atmosphere exerts pressure based on the weight of the air above, so the pressure reduces with rising altitude. This rate of pressure reduction with altitude is based on the temperature of the air, with the pressure of colder air reducing faster with altitude than warmer air. Therefore, a surface of constant pressure has a lower altitude at the poles than the equator. This animation shows the altitude above sea level (the geopotential height) of the 300 hectopascal (hPa) pressure surface for the whole globe from September 1, 2004, through September 5, 2004, during the period of Hurricane Frances in the western Atlantic Ocean and Typhoon Songda in the western Pacific Ocean. This pressure is about one-third of the normal pressure at sea level. The largest downward slope of this surface occurs in the mid-latitudes and is shown in yellow in the animation. At this region, air is trying to flow from the equator towards the poles to reduce the slope, but the rotation of the Earth forces the flow to divert to the east, forming the strong west-to-east jet stream flows in these regions. Frances and Songda can be seen as sharp yellow dots of reduced height in their respective locations.
