Description KidSat Images - Fires in Indonesia As the Space Shuttle Atlantis flew over the Indonesian archipelago on Saturday, September 27, middle school students across the country used the Kidsat camera to photograph the fires and smoke that blanket the island of Sumatra . A joint effort between 23 of the 52 schools participating in this mission, the KidSat camera was used to image a 140 km wide, 1950 km long strip that starts in the northwest (5.24 degrees N, 97.11 degrees E), and follows the Pegunungan Barisan range across the equator to the southern tip of Sumatra (7.44S, 106.1E). [Mission Elaspsed Time (MET) 00215343 - 00215750] Smoldering underground fires have raged uncontrolled for the past few weeks in Southeast Asia. Originally set to clear land for agriculture, the fires are usually extinguished by the annual monsoon rains. However, this year, the rains had not come due to El Nino which produces dry conditions in the Indonesia region. Due to the lack of trade winds, the seasonal warm waters in the eastern Pacific have spread over to South America. Consequently, the water temperature in Indonesia has dropped significantly. This decrease in temperature has not produced enough warm water vapor to produce the normal seasonal showers that usually encompass the area. The effects of the fires have been astronomical. So far the fire has been blamed for two fatal accidents and countless health hazards. At one point, the pollution index of the region reached 839. To put a relative point to this number, a pollution index of 300 is a equivalent of smoking 20 cigarettes a day. The smoke, during one time, blanketed an area that was larger than the continental United States. Currently, the fire's rage has been quelled by winds and rain which have lifted the smog and dampened the fires. However it is estimated that 100,000 fire fighters are needed to stop the fire. This KidSat image (MET 00215424) of the northern regions of Sumatra was captured on September 27, 1997 during the Shuttle flight STS-86. It is centered at 3.1 degrees S 98.6 degrees E and is 140 km wide and 205 km long. Smoke from the fires completely covers the land. The only indication of surface features is from the clouds that rise above the smoke over Danau Toba, the largest lake in Sumatra. The KidSat camera that photographed these fires is mounted in the overhead starboard window of the Shuttle Atlantis and operates before and after docking with Mir when the Shuttle's windows face the Earth. Students on the ground are linked to the camera through the Internet and a series of satellites. Commands are sent from middle schools through a Mission Operations Gateway at the University of California, San Diego, to a Thinkpad on the Shuttle flight deck. Images are transmitted back to the Jet Propulsion Laboratory where they are immediately placed on the Internet for the KidSat students and the rest of the world to view and use. High school and undergraduate students work in collaboration with scientists and engineers to develop and operate the KidSat systems. Curriculum developed by The Johns Hopkins University Institute for the Academic Advancement of Youth is used in the middle school classrooms to encourage scientific inquiry based on the images.

Description This image shows a 40-kilometer (25-mile) wide strip of digital topographic data superimposed on an optical photograph of the western United States. Both images were acquired during the STS-68 flight in October 1994. The digital data were acquired by the Spaceborne Imaging Radar C/X-Band Synthetic Aperture radar system, while the photograph was taken by the Space Shuttle astronauts. The view is looking to the east from above California's central valley (the dark area seen at the bottom of the image) across the snow-covered Sierra Nevada Mountains to the basin and range province of western Nevada. In the strip of topographic data, the different colors indicate elevation, with green being lowest and white being highest. The swath covers blue-colored Lake Tahoe on the left (north) and Mono Lake on the right. For comparison, the white lines indicate the 225- kilometer (140-mile) wide swath that will be mapped in a single pass by the Shuttle Radar Topography Mapper (SRTM) instrument, now scheduled to fly on the Space Shuttle in May 2000. The ability to cover a swath this wide will allow SRTM to completely map all the land surface between plus and minus 60 degrees latitude in a single 11-day flight. This is about 80% of Earth's total land area. SRTM, is a cooperative project between NASA and the Defense Mapping Agency of the U.S. Department of Defense that will be managed by the Jet Propulsion Laboratory for NASA's Office of Mission to Planet Earth. #####

Description Alex Amerri and Jenny Shanley, Kidsat Gaza Strip, Mediterranean Sea KidSat Image STS081.ESC.01002601 This image, taken with the KidSat digital camera aboard the space shuttle Atlantis during STS-81, was requested by Buist Academy School in Charleston, S.C. for the purpose of studying the coast of Israel and the Mediterranean Sea. The Kidsat electronic still camera, using a 50 mm lens, was used to take this picture which covers an area 102.25 km long and 152.98 km wide. The image is centered at 32.7 degrees north latitude, 34.22 degrees east longitude. Due to shuttle orientation, north is located at approximately eleven o'clock in this image. The Gaza Strip is inhabited by more than 800,000 Palestinian Arabs and approximately 4,800 Jewish settlers. This image shows the Gaza Strip and the Mediterranean Sea. The border can be seen within the image because of a difference in vegetation patterns, the Egyptian side being less vegetated perhaps due to heavy use of the land for grazing. Like the West Bank, the Gaza Strip was included as part of the British Mandate that lasted from 1917 to 1948. In 1948, an area west of the Jordan River was given to the Jewish people, and the country of Israel was established. Palestinian refugees settled in Gaza and in the West Bank. Since 1948, the Arabs and the Israelis have fought four wars over land. More recently, peace negotiations have occurred between Israeli Prime Minister Benjamin Netanyahu and Palestinian Authority President Yasser Arafat. KidSat gives students across the country a chance to view and learn about Earth using and commanding their own instruments in space. The KidSat project is a result of the effort and collaboration of Johns Hopkins University's Institute for Academic Advancement of Youth, the University of California, San Diego, and NASA's Jet Propulsion Laboratory. KidSat includes a payload of digital still and video cameras that fly on the Space Shuttle. Students operate these cameras from their classrooms, sending instructions to KidSat Mission Control Center at UC San Diego via the Internet to photograph specific regions of Earth they wish to study. Image data are sent to the KidSat data system during the mission and these images are accessible in the classroom in real time, again using the Internet. At JPL, students on the exploration team research the surrounding area of images and write a summary of its history as shown above. The KidSat project allows students to explore Earth from space and learn about its past and its fragile, ever-changing environment. Images and student results will be posted on the KidSat home page. Interested public school districts, teachers, and students may view the images and information provided by students during the mission via this World Wide Web site: http://www.jpl.nasa.gov/kidsat The KidSat pilot program is sponsored by NASA's Office of Human Resources and Education, with support from the Offices of Space Flight, Mission to Planet Earth and Space Science. #####

Description Conray Tseng, KidSat KidSat Image STS081.ESC.01002012 This KidSat image spans the region of Venetia from the city of Venice, Italy, on the coast of the Adriatic Sea north to the snow-capped Alps. Venice appears in the upper right part of the image, and the Alps appear in the upper left. This image is 97.78 km long by 146.31 km wide and is centered at 45.56 degrees north latitude, 11.48 degrees east longitude. Due to shuttle orientation, north is located at approximately ten o'clock in this image. It was taken by the KidSat electronic still camera, using a 50 mm lens, from the Space Shuttle Atlantis flight STS-81 at an altitude of 264.57 km. The image was requested by the Buist Academy Student Mission Operations Center in Charleston, South Carolina. The students will use the image in their classrooms to study the rivers and channels of Venice and to compare the cities of Venice and Paris, France. Venice's Grand Canal is barely visible in the image. Venice was one of the centers of science, knowledge and art during the Renaissance, as well as a major trade center for goods from Asia. Located near fishing and forest resources, it was first settled by a variety of people that included war refugees from Troy and immigrants from what are now the Slavic nations. The first settlement, consisting mostly of wood buildings, was destroyed after a massive sea quake, little remains of the original city. Settlements spread to encompass the islands in the mouth of the river Brenta and now cover a total 117 islands. In the nearby Alps are several waterfalls which, since 1977, have been the site of many ice climbing missions. KidSat gives students across the country a chance to view and learn about Earth using and commanding their own instruments in space. The KidSat project is a result of the effort and collaboration of NASA's Jet Propulsion Laboratory, Johns Hopkins University's Institute for Academic Advancement of Youth and the University of California, San Diego.

Date 5/1/00
Description This electronic nose, developed and built at NASA's Jet Propulsion Laboratory, Pasadena, Calif., was flown on the Space Shuttle during Mission STS-95 in October 1998. The E-Nose was able to determine changes in humidity accurately, but none of the 10 contaminants the E-Nose was trained to monitor was present. A cabin humidity monitor confirmed the humidity changes, while results of contaminant monitoring were confirmed using air samples brought back from the flight. Researchers are continuing to further develop E-Nose's capability to detect various odors and differentiate between those that signify danger and those that do not. This is especially important for the space station and any future space outpost that features a closed human habitat. Size and power requirements are important, too, since quarters will be constricted. The unit shown is only about the size of a large paperback and weighs 1.4 kilograms (about 3 pounds), including the small operating computer to the left.

Description Middle school students across the country photographed the fires and smoke over southern Sumatra from a camera aboard the Space Shuttle Atlantis September 27. A joint effort between 23 of the 52 schools participating in this mission, the KidSat camera was used to image a 140 km wide, 1950 km long strip that starts in the northwest (5.24 degrees N, 97.11 degrees E), and follows the Pegunungan Barisan range across the equator to the southern tip of Sumatra 7.44S, 106.1E [MET 00215343 - 00215750]. Smoldering underground fires have raged uncontrolled for the past few weeks in Southeast Asia. Originally set to clear land for agriculture, the fires are usually extinguished by the annual monsoon rains. However, this year, the rains had not come due to El Nino which produces dry conditions in the Indonesia region. Due to the lack of trade winds, the seasonal warm waters in the eastern Pacific have spread over to South America. Consequently, the water temperature in Indonesia has dropped significantly. This decrease in temperature has not produced enough warm water vapor to produce the normal seasonal showers that usually encompass the area. The fire has now been blamed for two fatal accidents and countless health hazards. At one point, the pollution index of the region reached 839. To put a relative point to this number, a pollution index of 300 is a equivalent of smoking 20 cigarettes a day. The smoke, during one time, blanketed an area that was larger than the continental United States. Currently, the fire's rage has been quelled by winds and rain which have lifted the smog and dampened the fires. However it is estimated that 100,000 fire fighters are needed to stop the fire. The KidSat image shown here is a mosaic of three images of the 16 image series (Mission Elapsed Time) 00215624, 00215637, 00215701, the center latitude and longitude of each image, respectively, is 3.0 degrees S 102.9 degrees E, 3.7 degrees S 103.4 degrees E, 4.9 degrees S 104.3 degrees E and is 140 km wide and 400 km long. The images were captured on September 27, 1997 during Shuttle flight STS-86. Starting in the south (right) and traveling northwest (left), a clear view is visible of the southern tip of Sumatra with the volcanoes that make up the backbone of the island appearing darker than the surrounding land. Further northwest, the first smoke plumes appear in the rain forests east of the mountains where land is being cleared for palm plantations, the plumes indicate a prevailing wind to the northwest. Within a short distance, the region becomes completely blanketed in smoke with only the peaks of the volcanoes rising above the gray haze layer. The KidSat camera that photographed these fires is mounted in the overhead starboard window of the Shuttle Atlantis and operates before and after docking with Mir when the Shuttle's windows face the Earth. Students on the ground are linked to the camera through the Internet and a series of satellites. High school and undergraduate students work in collaboration with scientists and engineers to develop and operate the KidSat systems. Curriculum developed by The Johns Hopkins University Institute for the Academic Advancement of Youth is used in the middle school classrooms to encourage scientific inquiry based on the images.

Description This is a three-dimensional perspective view of a false-color image of the eastern part of the Big Island of Hawaii. It was produced using all three radar frequencies -- X-band, C-band and L-band -- from the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) flying on the space shuttle Endeavour, overlaid on a U.S. Geological Survey digital elevation map. Visible in the center of the image in blue are the summit crater (Kilauea Caldera) which contains the smaller Halemaumau Crater, and the line of collapse craters below them that form the Chain of Craters Road. The image was acquired on April 12, 1994 during orbit 52 of the space shuttle. The area shown is approximately 34 by 57 kilometers (21 by 35 miles) with the top of the image pointing toward northwest. The image is centered at about 155.25 degrees west longitude and 19.5 degrees north latitude. The false colors are created by displaying three radar channels of different frequency. Red areas correspond to high backscatter at L-HV polarization, while green areas exhibit high backscatter at C-HV polarization. Finally blue shows high return at X-VV polarization. Using this color scheme, the rain forest appears bright on the image, while the green areas correspond to lower vegetation. The lava flows have different colors depending on their types and are easily recognizable due to their shapes. The flows at the top of the image originated from the Mauna Loa volcano. Kilauea volcano has been almost continuously active for more than the last 11 years. Field teams that were on the ground specifically to support these radar observations report that there was vigorous surface activity about 400 meters (one-quarter mile) inland from the coast. A moving lava flow about 200 meters (650 feet) in length was observed at the time of the shuttle overflight, raising the possibility that subsequent images taken during this mission will show changes in the landscape. Currently, most of the lava that is erupted travels the 8 kilometers (5 miles) from the Pu'u O'o crater (the active vent) just outside this image to the coast through a series of lava tubes, but in the past there have been many large lava flows that have traveled this distance, destroying houses and parts of the Hawaii Volcanoes National Park. This SIR-C/X-SAR image shows two types of lava flows that are common to Hawaiian volcanoes. Pahoehoe lava flows are relatively smooth, and appear very dark blue because much of the radar energy is reflected away from the radar. In contrast other lava flows are relatively rough and bounce much of the radar energy back to the radar, making that part of the image bright blue. This radar image is valuable because it allows scientists to study an evolving lava flow field from the Pu'u O'o vent. Much of the area on the northeast side (right) of the volcano is covered with tropical rain forest, and because trees reflect a lot of the radar energy, the forest appears bright in this radar scene. The linear feature running from Kilauea Crater to the right of the image is Highway 11 leading to the city of Hilo which is located just beyond the right edge of this image. ----- Spaceborne Imaging Radar-C and X-Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth.

Date 10/3/94
Description This is a radar image of Mount Rainier in Washington state. The volcano last erupted about 150 years ago and numerous large floods and debris flows have originated on its slopes during the last century. Today the volcano is heavily mantled with glaciers and snowfields. More than 100,000 people live on young volcanic mudflows less than 10,000 years old and, consequently, are within the range of future, devastating mudslides. This image was acquired by the Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) aboard the space shuttle Endeavour on its 20th orbit on October 1, 1994. The area shown in the image is approximately 59 kilometers by 60 kilometers (36.5 miles by 37 miles). North is toward the top left of the image, which was composed by assigning red and green colors to the L-band, horizontally transmitted and vertically, and the L- band, horizontally transmitted and vertically received. Blue indicates the C-band, horizontally transmitted and vertically received. In addition to highlighting topographic slopes facing the space shuttle, SIR-C records rugged areas as brighter and smooth areas as darker. The scene was illuminated by the shuttle's radar from the northwest so that northwest-facing slopes are brighter and southeast-facing slopes are dark. Forested regions are pale green in color, clear cuts and bare ground are bluish or purple, ice is dark green and white. The round cone at the center of the image is the 14,435-foot (4,399- meter) active volcano, Mount Rainier. On the lower slopes is a zone of rock ridges and rubble (purple to reddish) above coniferous forests (in yellow/green). The western boundary of Mount Rainier National Park is seen as a transition from protected, old-growth forest to heavily logged private land, a mosaic of recent clear cuts (bright purple/blue) and partially regrown timber plantations (pale blue). The prominent river seen curving away from the mountain at the top of the image (to the northwest) is the White River, and the river leaving the mountain at the bottom right of the image (south) is the Nisqually River, which flows out of the Nisqually glacier on the mountain. The river leaving to the left of the mountain is the Carbon River, leading west and north toward heavily populated regions near Tacoma. The dark patch at the top right of the image is Bumping Lake. Other dark areas seen to the right of ridges throughout the image are radar shadow zones. Radar images can be used to study the volcanic structure and the surrounding regions with linear rock boundaries and faults. In addition, the recovery of forested lands from natural disasters and the success of reforestation programs can also be monitored. Ultimately this data may be used to study the advance and retreat of glaciers and other forces of global change. ----- 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 false-color composite radar image of the Mammoth Mountain area in the Sierra Nevada Mountains, California, was acquired by the Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar aboard the space shuttle Endeavour on its 67th orbit on October 3, 1994. The image is centered at 37.6 degrees north latitude and 119.0 degrees west longitude. The area is about 39 kilometers by 51 kilometers (24 miles by 31 miles). North is toward the bottom, about 45 degrees to the right. In this image, red was created using L-band (horizontally transmitted/ vertically received) polarization data, green was created using C-band (horizontally transmitted/vertically received) polarization data, and blue was created using C-band (horizontally transmitted and received) polarization data. Crawley Lake appears dark at the center left of the image, just above or south of Long Valley. The Mammoth Mountain ski area is visible at the top right of the scene. The red areas correspond to forests, the dark blue areas are bare surfaces and the green areas are short vegetation, mainly brush. The purple areas at the higher elevations in the upper part of the scene are discontinuous patches of snow cover from a September 28 storm. New, very thin snow was falling before and during the second space shuttle pass. In parallel with the operational SIR-C data processing, an experimental effort is being conducted to test SAR data processing using the Jet Propulsion Laboratory's massively parallel supercomputing facility, centered around the Cray Research T3D . These experiments will assess the abilities of large supercomputers to produce high throughput Synthetic Aperture Radar processing in preparation for upcoming data- intensive SAR missions.

Date 10/7/94
Description This is an X-band image of an oil slick experiment conducted in the North Sea, Germany. The image is centered at 54.58 degrees north latitude and 7.48 degrees east longitude. This image was acquired by the Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) aboard the space shuttle Endeavour on October 6, 1994, during the second flight of the spaceborne radar. The experiment was designed to differentiate between petroleum oil spills and natural slicks floating on the sea surface. Two types of petroleum oil and six types of oils resembling natural sea surface slicks were poured on the sea surface from ships and a helicopter just before the space shuttle flew over the region. At the bottom of the image is the Sylt peninsula, a famous holiday resort. Twenty-six gallons (100 liters) of diesel oil was dissipated due to wave action before the shuttle reached the site. The oil spill seen at the uppermost part of the image is about 105 gallons (400 liters) of heavy heating oil and the largest spill is about 58 gallons (220 liters) of oleyl alcohol, resembling a "natural oil" like the remaining five spills used to imitate natural slicks that have occurred offshore from various states. The volume of these other oils spilled on the ocean surface during the five experimental spills varied from 16 gallons to 21 gallons (60 liters to 80 liters). The distance between neighboring spills was about half a mile (800 meters) at the most. The largest slick later thinned out to monomolecular sheets of about 10 millimeters, which is the dimension of a molecule. Oceanographers found that SIR-C/X-SAR was able to clearly distinguish the oil slicks from algae products dumped nearby. Preliminary indications are that various types of slicks may be distinguished, especially when other radar wavelengths are included in the analysis. Radar imaging of the world's oceans on a continuing basis may allow oceanographers in the future to detect and clean up oil spills much more swiftly than is currently possible. ----- Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth.

Description An area near Long Valley, California, was mapped by the Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar aboard the space shuttle Endeavor on April 13, 1994, during the first flight of the radar instrument, and on October 4, 1994, during the second flight of the radar instrument. The orbital configurations of the two data sets were ideal for interferometric combination -- that is overlaying the data from one image onto a second image of the same area to create an elevation map and obtain estimates of topography. Once the topography is known, any radar-induced distortions can be removed and the radar data can be geometrically projected directly onto a standard map grid for use in a geographical information system. The 50 kilometer by 50 kilometer (31 miles by 31 miles) map shown here is entirely derived from SIR-C L-band radar (horizontally transmitted and received) results. The color shown in this image is produced from the interferometrically determined elevations, while the brightness is determined by the radar backscatter. The map is in Universal Transverse Mercator (UTM) coordinates. Elevation contour lines are shown every 50 meters (164 feet). Crowley Lake is the dark feature near the south edge of the map. The Adobe Valley in the north and the Long Valley in the south are separated by the Glass Mountain Ridge, which runs through the center of the image. The height accuracy of the interferometrically derived digital elevation model is estimated to be 20 meters (66 feet) in this image. ----- Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth.

10/10/94
Date 10/10/94
Description This is a deformation map of the south flank of Kilauea volcano on the big island of Hawaii, centered at 19.5 degrees north latitude and 155.25 degrees west longitude. The map was created by combining interferometric radar data -- that is data acquired on different passes of the space shuttle which are then overlayed to obtain elevation information -- acquired by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar during its first flight in April 1994 and its second flight in October 1994. The area shown is approximately 40 kilometers by 80 kilometers (25 miles by 50 miles). North is toward the upper left of the image. The colors indicate the displacement of the surface in the direction that the radar instrument was pointed (toward the right of the image) in the six months between images. The analysis of ground movement is preliminary, but appears consistent with the motions detected by the Global Positioning System ground receivers that have been used over the past five years. The south flank of the Kilauea volcano is among the most rapidly deforming terrains on Earth. Several regions show motions over the six-month time period. Most obvious is at the base of Hilina Pali, where 10 centimeters (4 inches) or more of crustal deformation can be seen in a concentrated area near the coastline. On a more localized scale, the currently active Pu'u O'o summit also shows about 10 centimeters (4 inches) of change near the vent area. Finally, there are indications of additional movement along the upper southwest rift zone, just below the Kilauea caldera in the image. Deformation of the south flank is believed to be the result of movements along faults deep beneath the surface of the volcano, as well as injections of magma, or molten rock, into the volcano's "plumbing" system. Detection of ground motions from space has proven to be a unique capability of imaging radar technology. Scientists hope to use deformation data acquired by SIR-C/X-SAR and future imaging radar missions to help in better understanding the processes responsible for volcanic eruptions and earthquakes. ----- Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth.

Description These images are composites of the complete radar image collection obtained by the Magellan mission. The Magellan spacecraft was launched aboard space shuttle Atlantis in May 1989 and began mapping the surface of Venus in September 1990. The spacecraft continued to orbit Venus for four years, returning high-resolution images, altimetry, thermal emissions and gravity maps of 98 percent of the surface. Magellan spacecraft operations ended on October 12, 1994, when the radio contact was lost with the spacecraft during its controlled descent into the deeper portions of the Venusian atmosphere. The surface of Venus is displayed in these five global views. The center image (A) is centered at Venus’s north pole. The other four images are centered around the equator of Venus at (B) 0 degrees longitude, (C) 90 degrees east longitude, (D) 180 degrees and (E) 270 degrees east longitude. Magellan synthetic aperture radar mosaics are mapped onto a rectangular latitude-longitude grid to create this image. Data gaps are filled with Pioneer-Venus Orbiter altimetric data, or a constant mid- range value. Simulated color is used to enhance small-scale structure. The simulated hues are based on color images recorded by the Soviet Venera 13 and 14 spacecraft. The bright region near the center in the polar view is Maxwell Montes, the highest mountain range on Venus. Ovda Regio is centered in the (C) 90 degrees east longitude view. Atla Regio is seen prominently in the (D) 180 east longitude view. The scattered dark patches in this image are halos surrounding some of the younger impact craters. This global data set reveals a number of craters consistent with an average Venus surface age of 300 million to 500 million years.

Description This image is a composite of the complete radar image collection obtained by the Magellan mission. The Magellan spacecraft was launched aboard space shuttle Atlantis in May 1989 and began mapping the surface of Venus in September 1990. The spacecraft continued to orbit Venus for four years, returning high- resolution images, altimetry, thermal emissions and gravity maps of 98 percent of the surface. Magellan spacecraft operations ended on October 12, 1994, when the radio contact was lost with the spacecraft during its controlled descent into the deeper portions of the Venusian atmosphere. Venus is displayed in this simple cylindrical map of the planet's surface. The right and left edges of the image are at 240 degrees east longitude. The top and bottom of the image are at 90 degrees north latitude and 90 degrees south latitude, respectively. Magellan synthetic aperture radar mosaics are mapped onto a rectangular latitude- longitude grid to create this image. Data gaps are filled with Pioneer-Venus Orbiter altimetric data, or a constant mid-range value. Simulated color is used to enhance small-scale structure. The simulated hues are based on color images recorded by the Soviet Venera 13 and 14 spacecraft. At the top, left of center, the bright region is Maxwell Montes, the highest mountain range on Venus. Extending along the equator to the right of center is Aphrodite Terra, a large highland region on Venus. The scattered dark patches in this image are halos surrounding some of the younger impact craters. This global data set reveals a number of craters consistent with an average Venus surface age of 300 million to 500 million years.

Description This pair of images illustrates the ability of multi-parameter radar imaging sensors such as the Spaceborne Imaging Radar-C/X- band Synthetic Aperture radar to detect climate- related changes on the Patagonian ice fields in the Andes Mountains of Chile and Argentina. The images show nearly the same area of the south Patagonian ice field as it was imaged during two space shuttle flights in 1994 that were conducted five-and-a-half months apart. The images, centered at 49.0 degrees south latitude and 73.5 degrees west longitude, include several large outlet glaciers. The images were acquired by SIR-C/X-SAR on board the space shuttle Endeavour during April and October 1994. The top image was acquired on April 14, 1994, at 10:46 p.m. local time, while the bottom image was acquired on October 5,1994, at 10:57 p.m. local time. Both were acquired during the 77th orbit of the space shuttle. The area shown is approximately 100 kilometers by 58 kilometers (62 miles by 36 miles) with north toward the upper right. The colors in the images were obtained using the following radar channels: red represents the C-band (horizontally transmitted and received), green represents the L-band (horizontally transmitted and received), blue represents the L-band (horizontally transmitted and vertically received). The overall dark tone of the colors in the central portion of the April image indicates that the interior of the ice field is covered with thick wet snow. The outlet glaciers, consisting of rough bare ice, are the brightly colored yellow and purple lobes which terminate at calving fronts into the dark waters of lakes and fiords. During the second mission the temperatures were colder and the corresponding change in snow and ice conditions is readily apparent by comparing the images. The interior of the ice field is brighter because of increased radar return from the dryer snow. The distinct green/orange boundary on the ice field indicates an abrupt change in the structure of the snowcap, a direct indication of the steep meteorological gradients known to exist in this region. The bluer color of the outlet glaciers is probably due to a thin snow cover. A portion of the terminus of the outlet glacier at the top left center of the images has advanced approximately 600 meters (1,970 feet) in the five-and-a- half months between the two missions. Because of the persistent cloud cover this observation was only possible by using the orbiting, remote imaging radar system. ----- 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.

6/1/95
Date 6/1/95
Description A NASA radar instrument has been successfully used to measure some of the fastest moving and most inaccessible glaciers in the world -- in Chile's huge, remote Patagonia ice fields -- demonstrating a technique that could produce more accurate predictions of glacial response to climate change and corresponding sea level changes. This image, produced with interferometric measurements made by the Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) flown on the Space Shuttle last fall, has provided the first detailed measurements of the mass and motion of the San Rafael Glacier. Very few measurements have been made of the Patagonian ice fields, which are the world's largest mid-latitude ice masses and account for more than 60 percent of the Southern Hemisphere's glacial area outside of Antarctica. These features make the area essential for climatologists attempting to understand the response of glaciers on a global scale to changes in climate, but the region's inaccessibility and inhospitable climate have made it nearly impossible for scientists to study its glacial topography, meteorology and changes over time. Currently, topographic data exist for only a few glaciers while no data exist for the vast interior of the ice fields. Velocity has been measured on only five of the more than 100 glaciers, and the data consist of only a few single-point measurements. The interferometry performed by the SIR-C/X-SAR was used to generate both a digital elevation model of the glaciers and a map of their ice motion on a pixel-per-pixel basis at very high resolution for the first time. The data were acquired from nearly the same position in space on October 9, 10 and 11, 1994, at L- band frequency (24-cm wavelength), vertically transmitted and received polarization, as the Space Shuttle Endeavor flew over several Patagonian outlet glaciers of the San Rafael Laguna. The area shown in these two images is 50 kilometers by 30 kilometers (30 miles by 18 miles) in size and is centered at 46.6 degrees south latitude, 73.8 degrees west longitude. North is toward the upper right. The top image is a digital elevation model of the scene, where color and saturation represent terrain height (between 0 meters and 2,000 meters or up to 6,500 feet) and brightness represents radar backscatter. Low elevations are shown in blue and high elevations are shown in pink. The digital elevation map of the glacier surface has a horizontal resolution of 15 meters (50 feet) and a vertical resolution of 10 meters (30 feet). High-resolution maps like these acquired over several years would allow scientists to calculate directly long-term changes in the mass of the glacier. The bottom image is a map of ice motion parallel to the radar look direction only, which is from the top of the image. Purple indicates ice motion away from the radar at more than 6 centimeters per day, dark blue is ice motion toward or away at less than 6 cm per day, light blue is motion toward the radar of 6 cm to 20 cm (about 2 to 8 inches) per day, green is motion toward the radar of 20 cm to 45 cm (about 8 to 18 inches) per day, yellow is 45 cm to 85 cm (about 18 to 33 inches) per day, orange is 85 cm to 180 cm (about 33 to 71 inches) per day, red is greater than 180 cm (71 inches) per day. The velocity estimates are accurate to within 5 millimeters per day. The largest velocities are recorded on the San Rafael Glacier in agreement with previous work. Other outlet glaciers exhibit ice velocities of less than 1 meter per day. Several kilometers before its terminus, (left of center) the velocity of the San Rafael Glacier exceeds 10 meters (32 feet) per day, and ice motion cannot be estimated from the data. There, a revisit time interval of less than 12 hours would have been necessary to estimate ice motion from interferometry data. The results however demonstrate that the radar interferometry technique permits the monitoring of glacier characteristics unattainable by any other means. ----- Spaceborne Imaging Radar-C and X-Synthetic Aperture Radar (SIR- C/X-SAR) are part of NASA's Mission to Planet Earth.

Images such as this -- obtained by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR-C/X-SAR) flying aboard the space shuttle Endeavor last fall -- can become an effective tool for urban planners who map and monitor land use patterns in urban, agricultural and wetland areas. Central Houston appears pink and white in the upper portion of the image, outlined and crisscrossed by freeways. The image was obtained on October 10, 1994, during the space shuttle's 167th orbit. The area shown is 100 kilometers by 60 kilometers (62 miles by 38 miles) and is centered at 29.38 degrees north latitude, 95.1 degrees west longitude. North is toward the upper left. The pink areas designate urban development while the green- and blue-patterned areas are agricultural fields. Black areas are bodies of water, including Galveston Bay along the right edge and the Gulf of Mexico at the bottom of the image. Interstate 45 runs from top to bottom through the image. The narrow island at the bottom of the image is Galveston Island, with the city of Galveston at its northeast (right) end. The dark cross in the upper center of the image is Hobby Airport. Ellington Air Force Base is visible below Hobby on the other side of Interstate 45. Clear Lake is the dark body of water in the middle right of the image. The green square just north of Clear Lake is Johnson Space Center, home of Mission Control and the astronaut training facilities. The black rectangle with a white center that appears to the left of the city center is the Houston Astrodome.

Date 6/22/95
Description This radar image of the Midland/Odessa region of West Texas, demonstrates an experimental technique, called ScanSAR, that allows scientists to rapidly image large areas of the Earth's surface. The large image covers an area 245 kilometers by 225 kilometers (152 miles by 139 miles). It was obtained by the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR- C/X-SAR) flying aboard the space shuttle Endeavour on October 5, 1994. The smaller inset image is a standard SIR-C image showing a portion of the same area, 100 kilometers by 57 kilometers (62 miles by 35 miles) and was taken during the first flight of SIR-C on April 14, 1994. The bright spots on the right side of the image are the cities of Odessa (left) and Midland (right), Texas. The Pecos River runs from the top center to the bottom center of the image. Along the left side of the image are, from top to bottom, parts of the Guadalupe, Davis and Santiago Mountains. North is toward the upper right. Unlike conventional radar imaging, in which a radar continuously illuminates a single ground swath as the space shuttle passes over the terrain, a Scansar radar illuminates several adjacent ground swaths almost simultaneously, by "scanning" the radar beam across a large area in a rapid sequence. The adjacent swaths, typically about 50 km (31 miles) wide, are then merged during ground processing to produce a single large scene. Illumination for this L-band scene is from the top of the image. The beams were scanned from the top of the scene to the bottom, as the shuttle flew from left to right. This scene was acquired in about 30 seconds. A normal SIR- C image is acquired in about 13 seconds. The ScanSAR mode will likely be used on future radar sensors to construct regional and possibly global radar images and topographic maps. The ScanSAR processor is being designed for 1996 implementation at NASA's Alaska SAR Facility, located at the University of Alaska Fairbanks, and will produce digital images from the forthcoming Canadian RADARSAT satellite.

title Earth's San Andreas Fault
date 02.11.2000
description The Earth's surface is broken. Cracks in the Earth's crust known as faults can run for hundreds of kilometers. These faults are frequently the sites of major earthquakes as the tectonic plates that cover the surface of the Earth shift. Pictured above is San Andreas Fault in California, one of the longest and most active faults. Visible as the linear feature to the right of the mountains, San Andreas Fault reaches 15 kilometers deep and is about 20 million years old. The above exaggerated-height image was created by combining radar deployed by the Space Shuttle Endeavour in February 2000 with a true-color Landsat picture. Along San Andreas Fault, the titanic Pacific Plate is shifting relative to the huge North American Plate by an average of a few centimeters per year. At that rate, in a few million years, the Earth's surface will look quite different than it does today.

description This pair of images illustrates the ability of multi-parameter radar imaging sensors such as the Spaceborne Imaging Radar-C/X-band Synthetic Aperture radar to detect climate- related changes on the Patagonian ice fields in the Andes Mountains of Chile and Argentina. The images show nearly the same area of the south Patagonian ice field as it was imaged during two space shuttle flights in 1994 that were conducted five-and-a-half months apart. The images, centered at 49.0 degrees south latitude and 73.5 degrees west longitude, include several large outlet glaciers. The images were acquired by SIR-C/X-SAR on board the space shuttle Endeavour during April and October 1994. The top image was acquired on April 14, 1994, at 10:46 p.m. local time, while the bottom image was acquired on October 5,1994, at 10:57 p.m. local time. Both were acquired during the 77th orbit of the space shuttle. The area shown is approximately 100 kilometers by 58 kilometers (62 miles by 36 miles) with north toward the upper right. The colors in the images were obtained using the following radar channels: red represents the C-band (horizontally transmitted and received), green represents the L-band (horizontally transmitted and received), blue represents the L-band (horizontally transmitted and vertically received). The overall dark tone of the colors in the central portion of the April image indicates that the interior of the ice field is covered with thick wet snow. The outlet glaciers, consisting of rough bare ice, are the brightly colored yellow and purple lobes which terminate at calving fronts into the dark waters of lakes and fiords. During the second mission the temperatures were colder and the corresponding change in snow and ice conditions is readily apparent by comparing the images. The interior of the ice field is brighter because of increased radar return from the dryer snow. The distinct green/orange boundary on the ice field indicates an abrupt change in the structure of the snowcap, a direct indication of the steep meteorological gradients known to exist in this region. The bluer color of the outlet glaciers is probably due to a thin snow cover. A portion of the terminus of the outlet glacier at the top left center of the images has advanced approximately 600 meters (1,970 feet) in the five-and-a-half months between the two missions. Because of the persistent cloud cover this observation was only possible by using the orbiting, remote imaging radar system. P-45740
