Uele River, Cleared Pasture Lands, Zaire, Africa

STS049-91-079 (7 - 16 May 1992) --- This 70mm frame, photographed from the Earth-orbiting Space Shuttle Endeavour, features a dendritic drainage pattern in Zaire. Cleared pasture land shows light green in this color photograph, in contrast to the dark, closed-canopy forest of Zaire. Remnant woodland along minor streams indicates the intricate drainage network of this hilly region. Scattered vegetation-free spots show the deep red, tropical soil of the region. The sediment-laden stream is the Vele River just west of the village of Niangara. A crew member used a 70mm handheld Hasselblad camera with a 250mm lens to record the image.

After a 19 month rainfall deficiency, heavy rainfall during January 2004 brought drought relief to much of northern Queensland; these images were acquired by NASA Terra spacecraft.

Colorado as seen from STS-58

STS058-89-013 (18 Oct-1 Nov 1993) --- An oblique westward view, across the wheat fields and cattle pastures, of eastern Colorado to the Front Range of the Rocky Mountains. Denver is bisected at the center of the right edge of the frame. Pikes Peak and Colorado Springs are left of center, and the Arkansas River Valley with Canyon City and the Royal Gorge are along the left edge of the frame. This view shows the startling contrast between the nearly-flat High Plains and the ancient geological uplift of the Rockies.

Detroit, MI, Toledo, OH and Lake Erie

SL2-05-390 (22 June 1973) --- Greater Detroit (42.0N, 82.5W) is located at the southeastern border of Michigan on the Detroit River across from Windsor, Ontario, Canada and Lake Huron to the north. The river connecting Lake Erie is a channel left over from the Ice Age Glaciers. The land use pattern in this scene is typical of this part of the upper Midwest. The once extensive forests have been cleared for farmland and pasture, but narrow rows of trees still line farm boundaries. Photo credit: NASA

Agricultural and Ranching area, Rio Sao Francisco, Brazil

STS035-73-082 (2-10 Dec 1990) --- This agricultural and ranching area, Rio Sao Francisco, Brazil (13.0S, 43.5W) has been under study for several years. See scene STS-31-92-045 for comparison. This area has many small single family subsistence farms, large square and rectangular commercial farms and pastures for livestock grazing. Over the several years of observation, the number and size of farms has increased and center-pivot, swing-arm irrigation systems have been installed.

Fall Harvest in Kazakhstan

September 22, the autumnal equinox, marks the beginning of fall in the Northern Hemisphere, but the fall harvest begins early in the harsh continental climate of eastern Kazakhstan. By September 9, 2013, when the Operational Land Imager (OLI) on the Landsat 8 satellite acquired this image, several fields were already harvested and bare. Others were dark green with pasture grasses or ripening crops. The fields fill the contours of the land, running long and narrow down mountain valleys and spreading in large squares over the plains. Agriculture is an important segment of the economy in Kazakhstan: the country’s dry climate is ideal for producing high quality wheat for export. However, 61 percent of the country’s agricultural land is pasture for livestock. The area shown in this image, far eastern Kazakhstan near the Chinese border, is a minor wheat-growing region and may also produce sunflowers, barley, and other food crops. An artifact of Soviet-era collective farms, most of the farms in Kazakhstan are large, covering more than 5,000 hectares (12,500 acres). Some of the larger fields in the image reflect the big business side of agriculture. However, family farms and small agriculture businesses account for 35 percent of the country’s agricultural production, and some of these are visible as well, particularly in the uneven hills and mountains. Nearly all agriculture in Kazakhstan is rain fed. Farmers in this region have designed their fields to take advantage of rain flowing down hills, allowing the natural shape of the land to channel water to crops. The effect is a mosaic of green and tan with tones matching the natural vegetation in the mountains to the north.

Earth observation taken by the Expedition 29 crew

ISS029-E-008032 (17 Sept. 2011) --- Fires along the Rio Xingu, Brazil are featured in this image photographed by an Expedition 29 crew member on the International Space Station. The rain forest of South America, also known as ?Amazonia??the largest such forest on Earth?has been undergoing a continual and accelerated land use conversion process into farmlands (including pasture for livestock) since the early 1960s. This process has typically been achieved by clearing of the forest using fire ? ?slash and burn? ? followed by planting of crops. The generally infertile soils of the region make sustainable farming difficult; this drives more forest conversion into new farmland. The area of clearing can be considerable, and as the deforested regions are easily identifiable and measurable from space the rate of deforestation is likewise easy to track. This detailed photograph illustrates slash-and-burn forest clearing along the Xingu River (Rio) in the northeast of the state of Matto Grasso, Brazil. The perspective of this image allows for a striking visualization of both the horizontal position and extent of the fire lines next to the river, as well as providing a sense of the vertical structure of the smoke plumes due to the viewing angle and shadowing. Light colored areas within the river channel are sand bars, which show that the river is in its annual low-flow/ low water stage. For a sense of scale, the Xingu River channel within the view is approximately 63 kilometers long. Rivers in Amazonia are its natural highways, which may explain why the burning is occurring right next to the Xingu River, one of Amazonia?s largest. In recent years, preservation has gained traction in the region as a result of such considerations as new valuation of the ecosystem services provided by the forest, concerns about the impact of widespread burning on global climate change, and greater sensitivity to the ethnic and biological heritage of Amazonia.

Earth observation taken by the Expedition 33 crew.

ISS033-E-022852 (18 Nov. 2012) --- This view, photographed by an Expedition 33 crew member on the International Space Station, highlights the 24-kilometer wide Aso caldera on the Japanese Island of Kyushu, formed during four explosive eruptions that took place from 300,000 to 90,000 years ago, according to scientists. These major eruptions produced pyroclastic flows and airfall tephra that covered much of Kyushu. As the eruptions emptied the magma chambers beneath the ancient volcanoes, they collapsed ? forming the caldera. Shadows highlight the caldera rim at left, while green vegetation covers slopes between the rim and caldera floor at right. Volcanic activity continued in the caldera following its formation, represented by 17 younger volcanoes including Naka-dake at center. Naka-dake is one of Japan?s most active volcanoes, with ash plumes produced from the summit crater as recently as June 2011. Another prominent crater, Kusasenri, is visible to the west of Naka-dake. This crater is the site of the Aso Volcano Museum as well as pasture for cows and horses. The Aso caldera floor is largely occupied by urban and agricultural land uses that present a gray to white speckled appearance in the image. Fields and cities surround the younger volcanic structures in the caldera center to the north, west, and south. Tan to yellow-brown regions along the crater rim, and along the lower slopes of the younger volcanic highlands in the central caldera, are lacking the dense tree cover indicated by greener areas in the image.

Landsat View: Western Suburbs of Chicago, Illinois

Forty miles west of downtown Chicago, the Fox River meanders its way through what has become the westernmost reaches of metropolitan Chicago, where the sprawling metropolis meets the hinterlands. While Chicago itself has seen a seven percent population decline during the last decade, the population of its metropolitan region, "Chicagoland," has steadily increased. These two natural-color Landsat 5 images acquired a quarter-century apart (on May 2, 1985, and May 23, 2010), stand witness to the soaring growth of this region. Aurora, Illinois’ second largest city, is the silvery-green region to the left hugging the Fox River, just south of the I-88 (North is to the right in this image); Carpentersville is found on the rightmost side, north of the I-90. From 1985 to 2010 a development explosion can been seen as the browns of pasture lands give way to silvery-green suburban areas and large white-colored business districts spring up along and east of the river. A major expansion of Dupage Airport appears in the middle of the 2010 image, and the circular-shaped region north of the I-88 and east of the Fox River, visible on both images, is the Department of Energy’s Fermilab. ---- NASA and the U.S. Department of the Interior through the U.S. Geological Survey (USGS) jointly manage Landsat, and the USGS preserves a 40-year archive of Landsat images that is freely available over the Internet. The next Landsat satellite, now known as the Landsat Data Continuity Mission (LDCM) and later to be called Landsat 8, is scheduled for launch in 2013. In honor of Landsat’s 40th anniversary in July 2012, the USGS released the LandsatLook viewer – a quick, simple way to go forward and backward in time, pulling images of anywhere in the world out of the Landsat archive. <a href="http://www.nasa.gov/audience/formedia/features/MP_Photo_Guidelines.html" rel="nofollow">NASA image use policy.</a> <a href="http://www.nasa.gov/centers/goddard/home/index.html" rel="nofollow">NASA Goddard Space Flight Center</a> enables NASA’s mission through four scientific endeavors: Earth Science, Heliophysics, Solar System Exploration, and Astrophysics.

$The NISAR (NASA-ISRO Synthetic Aperture Radar) Earth-observing radar satellite's L-band synthetic aperture radar (SAR) system captured an image of a portion of northeastern North Dakota straddling Grand Forks and Walsh counties on Aug. 23, 2025. Produced by scientists on the NISAR science team, the image shows forests and wetlands on the banks of the Forest River meandering through the middle of the frame from west to east and farmland to the north and south. The darker agricultural plots are fallow fields, while the lighter colors represent the presence of pasture or crops, such as soybean and corn. Circular patterns indicate the use of center-pivot irrigation. The satellite is a joint effort between NASA and the Indian Space Research Organisation (ISRO) and is the first satellite to combine L-band and S-band radar systems. The satellite's L-band system, provided by NASA's Jet Propulsion Laboratory in Southern California, uses a 10-inch (25-centimeter) wavelength that enables its signal to penetrate forest canopies and measure soil moisture as well as motion of ice surfaces and land down to fractions of an inch – a key measurement in understanding how the land surface moves before, during, and after earthquakes, volcanic eruptions, and landslides. The NISAR S-band radar, provided by ISRO's Space Applications Centre, uses a 4-inch (10-centimeter) microwave signal that's more sensitive to small vegetation, which makes it effective at monitoring certain types of agriculture and grassland ecosystems. Data used to create the image was collected during NISAR's commissioning phase, when the spacecraft's systems and instruments are powered on and tested. The NISAR mission will begin science operations in November, roughly 90 days after its July 30, 2025, launch from Satish Dhawan Space Centre on India's southeastern coast. Observations from NISAR will benefit humanity by helping researchers around the world better understand changes in our planet's surface, including its ice sheets, glaciers, and sea ice. It also will capture changes in forest and wetland ecosystems and track movement and deformation of our planet's crust by phenomena such as earthquakes, landslides, and volcanic activity. The global and rapid coverage from NISAR will provide unprecedented support for disaster response, producing data to assist in mitigating and assessing damage, with observations before and after catastrophic events available in short time frames. https://photojournal.jpl.nasa.gov/catalog/PIA26615$

Space Radar Image of Bahia

This is a color composite image of southern Bahia, Brazil, centered at 15.22 degree south latitude and 39.07 degrees west longitude. The image was acquired by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar aboard the space shuttle Endeavour on its 38th orbit of Earth on October 2, 1994. The image covers an area centered over the Una Biological Reserve, one the largest protected areas in northeastern Brazil. The 7,000-hectare reserve is administered by the Brazilian Institute for the Environment and is part of the larger Atlantic coastal forest, a narrow band of rain forest extending along the eastern coast of Brazil. The Atlantic coastal forest of southern Bahia is one of the world's most threatened and diverse ecosystems. Due to widespread settlement, only 2 to 5 percent of the original forest cover remains. Yet the region still contains an astounding variety of plants and animals, including a large number of endemic species. More than half of the region's tree species and 80 percent of its animal species are indigenous and found nowhere else on Earth. The Una Reserve is also the only federally protected habitat for the golden-headed lion tamarin, the yellow-breasted capuchin monkey and many other endangered species. In the past few years, scientists from Brazilian and international conservation organizations have coordinated efforts to study the biological diversity of this region and to develop practical and economically viable options for preserving the remaining primary forests in southern Bahia. The shuttle imaging radar is used in this study to identify various land uses and vegetation types, including remaining patches of primary forest, cabruca forest (cacao planted in the understory of the native forest), secondary forest, pasture and coastal mangrove. Standard remote-sensing technology that relies on light reflected from the forest canopy cannot accurately distinguish between cabruca and undisturbed forest. Optical remote sensing is also limited by the nearly continuous cloud cover in the region and heavy rainfall, which occurs more than 150 days each year. The ability of the shuttle radars to "see" through the forest canopy to the cultivated cacao below -- independent of weather or sunlight conditions --will allow researchers to distinguish forest from cabruca in unprecedented detail. This SIR-C/X-SAR image was produced by assigning red to the L-band, green to the C-band and blue to the X-band. The Una Reserve is located in the middle of the image west of the coastline and slightly northwest of Comandatuba River. The reserve's primary forests are easily detected by the pink areas in the image. The intensity of red in these areas is due to the high density of forest vegetation (biomass) detected by the radar's L-band (horizontally transmitted and vertically received) channel. Secondary forest is visible along the reserve's eastern border. The Serrado Mar mountain range is located in the top left portion of the image. Cabruca forest to the west of Una Reserve has a different texture and a yellow color. The removal of understory in cabruca forest reduces its biomass relative to primary forest, which changes the L-band and C-band penetration depth and returns, and produces a different texture and color in the image. The region along the Atlantic is mainly mangrove swamp, agricultural fields and urban areas. The high intensity of blue in this region is a result of increasing X-band return in areas covered with swamp and low vegetation. The image clearly separates the mangrove region (east of coastal Highway 001, shown in blue) from the taller and dryer forest west of the highway. The high resolution capability of SIR-C/X-SAR imaging and the sensitivity of its frequency and polarization channels to various land covers will be used for monitoring and mapping areas of importance for conservation. http://photojournal.jpl.nasa.gov/catalog/PIA01764

New Earth-Observing Instrument Installed on the International Space Station

In January 2013, a new Earth-observing instrument was installed on the International Space Station (ISS). ISERV Pathfinder consists of a commercial camera, a telescope, and a pointing system, all positioned to look through the Earth-facing window of ISS’s Destiny module. ISERV Pathfinder is intended as an engineering exercise, with the long-term goal of developing a system for providing imagery to developing nations as they monitor natural disasters and environmental concerns. The image above is the “first light” from the new ISERV camera system, taken at 1:44 p.m. local time on February 16, 2013. It shows the Rio San Pablo as it empties into the Golfo de Montijo in Veraguas, Panama. It is an ecological transition zone, changing from agriculture and pastures to mangrove forests, swamps, and estuary systems. The area has been designated a protected area by the National Environmental Authority (ANAM) of Panama and is listed as a “wetland of international importance” under the Ramsar Convention. (Note that the image is rotated so that north is to the upper right.) “ISERV’s full potential is yet to be seen, but we hope it will really make a difference in people’s lives,” said principal investigator Burgess Howell of NASA’s Marshall Space Flight Center. “For example, if an earthen dam gives way in Bhutan, we want to be able to show officials where the bridge is out or where a road is washed out or a power substation is inundated. This kind of information is critical to focus and speed rescue efforts.” The instrument will be controlled from NASA Marshall in Huntsville, Alabama, in collaboration with researchers at hubs in Central America, East Africa, and the Hindu Kush–Himalaya region. They will rely on positioning software to know where the space station is at each moment and to calculate the next chance to view a particular area on the ground. If there's a good viewing opportunity, the SERVIR team will instruct the camera to take high-resolution photographs at 3 to 7 frames per second, totaling as many as 100 images per pass. With a resolution down to 3.2 meters (10 feet), it will be possible to spot fairly small details and objects. The current mission will test the limitations of Pathfinder and identify measures for improvements in a more permanent system. For instance, the engineering team is working to determine how the geometry of the ISS window affects the imagery; how much sunlight is needed to capture clear images; and how the atmosphere affects that clarity. This characterization phase will last several weeks to a few months. Eventually, ISERV should be made available to the natural hazards community and to basic research scientists. ISERV is short for ISS SERVIR Environmental Research and Visualization system. Together with the U.S. Agency for International Development, NASA runs the SERVIR program to provide satellite data, maps, and other tools to environmental decisionmakers in developing countries.
