4/5/00
Date 4/5/00
Description Polar stratospheric clouds over Kiruna, Sweden, on Jan. 27, 2000. The colorful appearance of these clouds is due to the small size of their droplets and their high altitude, approximately 21,300 meters (70,000 ft). The small droplets in the clouds result in separation of light of different colors due to refraction of sunlight. Their high altitude allows for full solar illumination for up to 20 minutes following sunset at the ground. These clouds, which have long been called "Mother of Pearl" by Scandinavians, participate in a chain of events that leads to ozone depletion by human-produced chlorine. Between November 1999 and March 2000, the SAGE III Ozone Loss and Validation Experiment (SOLVE) provided scientists with measurements of ozone using a variety of satellite-, airplane-, balloon- and ground-based instruments. Scientists also obtained a comprehensive inventory of numerous other atmospheric gases and information on the physical and chemical properties of polar stratospheric clouds. The SOLVE mission was co-sponsored by the Upper Atmosphere Research Program, Atmospheric Effects of Aviation Project, Atmospheric Chemistry Modeling and Analysis Program, and Earth Observing System of NASA's Earth Science Enterprise as part of the validation program for the SAGE III instrument. Based primarily in Kiruna, Sweden, the campaign included scientists from the United States, Europe, Canada, Russia and Japan. A key aspect to the success of this mission was the permission to fly both NASA research aircraft over Russia. SOLVE was managed by the Ames Research Center, Moffett Field, CA, with extensive participation by science teams from Goddard Space Flight Center, Greenbelt, MD, Langley Research Center, Hampton, VA, and the Jet Propulsion Laboratory, Pasadena, CA, as well as a number of other government laboratories and universities. The ER-2 and DC-8 aircraft are based at Dryden Flight Research Center, Edwards, CA, and the U.S. balloon operations in Sweden were conducted by a team from the National Scientific Balloon Facility, Palestine, TX.

Description A NASA high-altitude research balloon climbing to study the composition of the Arctic stratosphere from the Esrange Balloon Launch Facility near Kiruna, Sweden. With its helium bubble expanding to the size of a large building while in the stratosphere, the balloon carried a payload of about 450 Kg. (1000 lbs) to an altitude of about 30,500 meters (100,000 ft.). Following flight, the instrument payload lands by parachute and is recovered for subsequent flights.

Description The NASA ER-2 high-altitude research plane on the runway of Kiruna, Sweden. The airplane -- a civilian variant of the U-2 reconnaissance plane capable of reaching altitudes as high as 21,330 meters (70,000 feet) -- carried into the stratosphere dozens of scientific instruments that measure the composition of Earth's ozone layer. The only person on board is the pilot, who must wear a pressurized spacesuit to guard against the dangers of high-altitude flight.

Description Multi-Angle Views of the Appalachian Mountains The true-color image at left is a downward-looking (nadir) view of the eastern United States, stretching from Lake Ontario to northern Georgia, and spanning the Appalachian Mountains. The three images to the right are also in true-color, taken by the forward 45.6-degree, 60.0-degree, and 70.5-degree cameras, respectively, of the Multi-angle Imaging SpectroRadiometer (MISR) instrument on NASA's Terra satellite. As the slant angle increases, the line- of-sight through the atmosphere grows longer, and a pall of haze over the Appalachians becomes progressively more apparent. You can see a similar effect by scanning from near-nadir to the horizon when standing on a mountain top or looking out an airplane window. MISR uses this multi-angle technique to monitor particulate pollution and to distinguish different types of haze. These observations reveal how airborne particles are interacting with sunlight, a measure of their impact on Earth's climate system. The images are about 400 km (250 miles) wide, and the spatial resolution is 1.1 kilometers (1,200 yards). North is toward the top. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology. #####
Titan Sea and Lake Superior
Description Titan Sea and Lake Superior
Full Description This side-by-side image shows a Cassini radar image (on the left) of what is the largest body of liquid ever found on Titan's north pole, compared to Lake Superior (on the right). This close-up is part of a larger image (see Titan (T25) Viewed by Cassini's Radar - Feb. 22, 2007) and offers strong evidence for seas on Titan. These seas are most likely liquid methane and ethane. This feature on Titan is at least 100,000 square kilometers (39,000 square miles), which is greater in extent than Lake Superior (82,000 square kilometers or 32,000 square miles), which is one of Earth's largest lakes. The feature covers a greater fraction of Titan than the largest terrestrial inland sea, the Black Sea. The Black Sea covers 0.085 percent of the surface of the Earth, this newly observed body on Titan covers at least 0.12 percent of the surface of Titan. Because of its size, scientists are calling it a sea. The image on the right is from the SeaWiFS project, NASA's Goddard Space Flight Center, Greenbelt, Md. 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 was designed, developed and assembled at JPL. The radar instrument was built by JPL and the Italian Space Agency, working with team members from the United States and several European countries.

Marjorie Townsend and SAS-1
Title Marjorie Townsend and SAS-1
Full Description Marjorie Townsend discusses the X-ray Explorer Satellite's performance with a colleague during preflight tests at NASA's Goddard Space Flight Center. Townsend, a Washington DC native, was the first woman to receive an engineering degree from The George Washington University. She joined NASA in 1959 and later advanced to become the project manager of the Small Astronomy Satellite (SAS) Program. The satellite shown in the picture, SAS-1, was the 42nd in NASA's Explorer series, a family of small, simple satellites sent to perform important scientific missions for minimal cost. The first Explorer satellite launched in 1958, months prior to the formation of NASA, initiating a program of exploration that has continued into the twenty-first century. SAS-1 continued the tradition of crucial science projects by carrying the first set of sensitive instruments designed to map X-ray sources both within and beyond our own galaxy, the Milky Way. Also known as Explorer 42 and the X-ray Explorer, it became the first American spacecraft launched by another country when an Italian space team launched it on December 12, 1970 from a mobile launch platform located in international waters off the coast of East Africa. It mapped the universe in X-ray wavelengths and discovered X-ray pulsars and evidence of black holes. The satellite was named Uhuru, which means freedom in Swahili, because it was launched from San Marco off the coast of Kenya on Kenya's Independence Day. In the 1970's the Italian Government made Townsend a Knight of the Italian Republic Order for her contributions to the United States-Italian space efforts. In 1990, Townsend joined BDM International Inc., as the director of Space Systems Engineering with the Space Science and Applications Division.

Title Applications Technology Satellite Testing
Full Description A test model of the Applications Technology Satellite (ATS) is seen during checkout activity in Chamber A of the Space Environment Simulation Laboratory at the Johnson Space Center (JSC) to see if the satellite's 30-feet diameter umbrella-shaped antenna would unfold properly in a space vacuum. The antenna is in an unfolded (deployed) position in this picture. For the test, the 65-feet diameter by 120 feet high vacuum chamber in Building 32 was pumped down to an equivalent altitude of 255,000 feet. The test model satellite is hung by cables from the chamber's dome. Engineers from the Goddard Space Flight Center (GSFC) not only wanted to test the antenna mechanism itself, but the efforts of the unfolding action on the whole satellite. For the test, the 54-feet span solar array "paddles" for generating the satellite's electrical power were spread in the orbit flight position, while the parabolic antenna was folded into a donut-shaped package beneath the solar ray booms. The 3,000 pound ATS-F was launched in the spring of 1974 atop a Titan IIIC launch vehicle into a 22,000-mile high synchronous orbit, first above the United States and later above India. ATS spacecraft prime contractor to the GSFC, Greenbelt, Maryland, was Fairchild Industries, Germantown, Maryland. This view is from outside the chamber looking through the huge doorway.

Big Blue Marble
Title Big Blue Marble
Full Description Though all looks peaceful in this image of the big blue marble taken by the GOES 8 weather satellite, one of two weather satellites designed and built by NASA but operated by the National Oceanic and Atmospheric Administration, statistically the United States has the world's most violent weather. In a typical year, the U.S. will endure some 10,000 violent thunderstorms, 5,000 floods, 1,000 tornadoes and several hurricanes. Improving weather prediction, therefore, always has been a top priority for meteorologists. Since its launch in 1994, GOES 8 has become indispensable for imaging clouds and measuring cloud heights?information scientists need for three- dimensional weather models. A companion weather satellite, GOES 10, was launched in 1997.

Title Satellite Imagery of Hurricane Dennis (WMS)
Abstract Hurricane Dennis started as a tropical depression on August 23, 1999, became a tropical storm on August 24, and was classified as a hurricane early on August 26, near the Bahamas. From August 26 through August 31, Dennis proceeded up the coast of the United States until it stalled off the coast of North Carolina for four days because the pressure trough that was pushing it out to sea left it behind. This animation shows images of Dennis during its hurricane period from August 26 through August 31, 1999, when the stall began. The images were taken by the GOES-8 satellite, a weather satellite in geostationary orbit above the western hemisphere. The continuous white cloud progression came from infrared images from GOES, and the yellowish clouds that come and go with the daylight came from data taken in the visible spectrum, also from GOES. The GOES images were not taken at regular times, so the hurricane appears to slow down when the time between images gets small and speed up when the time between images gets large.

Title NDVI Anomalies Show Areas of Likely Drought in the Western US (wide view)
Abstract Satellite data can gauge the health of plants, which is a good indicator of drought. Satellite imagery shows changes in vegetation between 1999 and 2003. The Normalized Difference Vegetation Index (NDVI) measures how dense and green plant leaves are, which suggests overall vegetative health. The NDVI images are also useful as a measure of drought when compared to 'normal' plant health. NASA scientists calculate average NDVI values for an area to find out what is normal at a particular time of year. This data was measured by the vegetation instrument on Europe's SPOT satellite provided by DigitalGlobe/SPOT, under agreement with the U.S. Department of Agriculture Foreign Agricultural Service (USDA/FAS). In 2002, drought had settled across the Midwest. Large dark brown sections of eastern Colorado show where vegetation was less lush and healthy than normal. This version of the visualization is a wide view showing the western United States.

Title Urban Signatures: Evaporation (WMS)
Abstract Big cities influence the environment around them. For example, urban areas are typically warmer than their surroundings. Cities are strikingly visible in computer models that simulate the Earth's land surface. This visualization shows evaporation rates predicted by the Land Information System (LIS) for a day in June 2001. Evaporation is lower in the cities because water tends to run off pavement and into drains, rather than being absorbed by soil and plants from which it later evaporates. Only part of the global computation is shown, focusing on the highly urbanized northeast corridor in the United States, including the cities of Boston, New York, Philadelphia, Baltimore, and Washington.

Title Erythemal Index 2000: Push-in to the United States
Abstract The Erythemal Index is a measure of ultraviolet radiation (UV) at ground level on the Earth. UV exists to the left of the visible spectrum and is divided into three components (UV-A, UV-B and UV-C). UV-B (290-320 wavelengths) is the most dangerous form of UV radiation that can reach ground level. Atmospheric ozone shields life at the surface from most of the harmful components of solar radiation. Chemical processes in the atmosphere can effect the level of protection provided by the ozone in the upper atmosphere. This thinning of the atmospheric ozone in the stratosphere leads to elevated levels of UV-B at ground level and increases the risks of DNA damage in living organisms.

Title Urban Signatures: Thermal Radiation (WMS)
Abstract Big cities influence the environment around them. For example, urban areas are typically warmer than their surroundings. Cities are strikingly visible in computer models that simulate the Earth's land surface. This visualization shows outgoing thermal radiation predicted by the Land Information System (LIS) for a day in June 2001. Cities are warmer, so they emit more longwave (infrared) radiation. Only part of the global computation is shown, focusing on the highly urbanized northeast corridor in the United States, including the cities of Boston, New York, Philadelphia, Baltimore, and Washington.
