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.

First Human in Space
title First Human in Space
date 04.12.1961
description On April 12, 1961 Yuri Gagarin became the first human in space. News of his successful launch stunned the world and spurred the American space program to catch up. The name of his spacecraft was Vostok 1. Vostok 1 had two sections. One section was for Yuri. The second section was for supplies needed for Gagarin to live such as oxygen and water. Vostok 1 circled Earth at a speed of 27,400 kilometers per hour. The flight lasted 108 minutes. Vostok's reentry was controlled by a computer. Gagarin did not land inside of Vostok 1. He ejected from the spacecraft and landed by parachute. Born near Moscow, Russia on Mar. 9, 1934, Gagarin joined the Soviet Air Force in 1955. By 1959, he was training to be a cosmonaut. Gagarin was killed in a plane crash on Mar. 27, 1968. He was 34. *Image Credit*: NASA

Title 3-D Perspective Kamchatka Peninsula Russia
Full Description This perspective view shows the western side of the volcanically active Kamchatka Peninsula in eastern Russia. The image was generated using the first data collected during the Shuttle Radar Topography Mission (SRTM). In the foreground is the Sea of Okhotsk. Inland from the coast, vegetated floodplains and low relief hills rise toward snow capped peaks. The topographic effects on snow and vegetation distribution are very clear in this near-horizontal view. Forming the skyline is the Sredinnyy Khrebet, the volcanic mountain range that makes up the spine of the peninsula. High resolution SRTM topographic data will be used by geologists to study how volcanoes form and to understand the hazards posed by future eruptions. This image was generated using topographic data from SRTM and an enhanced true-color image from the Landsat 7 satellite. This image contains about 2,400 meters (7,880 feet) of total relief. The topographic expression was enhanced by adding artificial shading as calculated from the SRTM elevation model. The Landsat data was provided by the United States Geological Survey's Earth Resources Observations Systems (EROS) Data Center, Sioux Falls, South Dakota. SRTM, launched on February 11, 2000, used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. To collect the 3-D SRTM data, engineers added a 60- meter-long (200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. SRTM collected three dimensional measurements of nearly 80 percent of the Earth's surface. SRTM is a cooperative project between NASA, the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense, and the German and Italian space agencies. Size: 33.3 km (20.6 miles) wide x 136 km (84 miles) coast to skyline. Location: 58.3 deg. North lat., 160 deg. East long. Orientation: Easterly view, 2 degrees down from horizontal. Original Data Resolution: 30 meters (99 feet). Vertical Exaggeration: 3 times.

Title Artist's Conception of Space Station Freedom
Full Description Alan Chinchar's 1991 rendition of the Space Station Freedom in orbit. The painting depicts the completed space station. Earth is used as the image's backdrop with the Moon and Mars off in the distance. Freedom was to be a permanently crewed orbiting base to be completed in the mid 1990's. It was to have a crew of 4. Freedom was an attempt at international cooperation that attempted to incorporate the technological and economic assistance, of the United States, Canada, Japan, and nine European nations. The image shows four pressurized modules (three laboratories and a habitat module) and six large solar arrays which were expected to generate 56,000 watts of electricity for both scientific experiments and the daily operation of the station. Space Station Freedom never came to fruition. Instead, in 1993, the original partners, as well as Russia, pooled their resources to create the International Space Station.

Cosmonaut Yuri Gagarin
Title Cosmonaut Yuri Gagarin
Full Description Yuri Gagarin was born on March 9, 1934 in a town outside of Moscow, Russia. After graduating from secondary school in 1949, Gagarin went to several technical schools before joining the Orenburg Higher Air Force School in 1955. He began his cosmonaut training in 1960, along with 19 other candidates. On April 12, 1961 at 9:06 am Gagarin lifted off in the Vostok 1 spacecraft and after a 108-minute flight of extended microgravity, he parachuted safely to the ground in the Saratov region of the USSR. As the first human to fly in space, he successfully completed one orbit around the Earth. After his historic flight, Gagarin became an international symbol for the Soviet space program and in 1963 was appointed deputy director of the Cosmonaut Training Center. In 1966 he served as a backup crewmember for Soyuz 1 and on February 17, 1968, completed a graduate degree in technical sciences. Tragically, during flight training in a UTI-MiG-15 aircraft on March 27, 1968, Gagarin was killed when his plane crashed.

SOLAR FLARE LEAVES SUN QUAKI …
Description SOLAR FLARE LEAVES SUN QUAKING Scientists have shown for the first time that solar flares produce seismic waves in the Sun's interior that closely resemble those created by earthquakes on our planet. The researchers observed a flare-generated solar quake that contained about 40,000 times the energy released in the great earthquake that devastated San Francisco in 1906. The amount of energy released was enough to power the United States for 20 years at its current level of consumption, and was equivalent to an 11.3 magnitude earthquake, scientists calculated. Dr. Alexander G. Kosovichev, a senior research scientist from Stanford University, and Dr. Valentina V. Zharkova from Glasgow (United Kingdom) University found the tell-tale seismic signature in data on the Sun's surface collected by the Michelson Doppler Imager onboard the Solar and Heliospheric Observatory (SOHO) spacecraft immediately following a moderate-sized flare on July 9, 1996. "Although the flare was a moderate one, it still released an immense amount of energy," said Dr. Craig Deforest, a researcher with the SOHO project. "The energy released is equal to completely covering the Earth's continents with a yard of dynamite and detonating it all at once." SOHO is a joint project of the European Space Agency and NASA. The finding is reported in the May 28 issue of the journal Nature, and is the subject of a press conference at the spring meeting of the American Geophysical Union in Boston, Mass., May 27. The solar quake that the science team recorded looks much like ripples spreading from a rock dropped into a pool of water. But over the course of an hour, the solar waves traveled for a distance equal to 10 Earth diameters before fading into the fiery background of the Sun's photosphere. Unlike water ripples that travel outward at a constant velocity, the solar waves accelerated from an initial speed of 22,000 miles per hour to a maximum of 250,000 miles per hour before disappearing. "People have looked for evidence of seismic waves from flares before, but they didn't have a theory so they didn't know where to look," says Kosovichev. Several years ago Kosovichev and Zharkova developed a theory that can explain how a flare, which explodes in space above the Sun's surface, can generate a major seismic wave in the Sun's interior. According to the currently accepted model of solar flares, the primary explosion creates high-energy electrons (electrically charged subatomic particles). These are funneled down into a magnetic flux tube, an invisible tube of magnetic energy, and produce X-rays, microwaves and a shock wave that heats the solar surface. Kosovichev and Zharkova developed a theory that predicts the nature and magnitude of the shock waves that this beam of energetic electrons should create when they slam down into the solar atmosphere. Although their theory directed them to the right area to search for the seismic waves, the waves that they found were 10 times stronger than they had, predicted. "They were so strong that you can see them in the raw data," Kosovichev says. The solar seismic waves appear to be compression waves like the "P" waves generated by an earthquake. They travel throughout the Sun's interior. In fact, the waves should recombine on the opposite side of the Sun from the location of the flare to create a faint duplicate of the original ripple pattern, Kosovichev predicts. Now that they know how to find them, the SOHO scientists say that the seismic waves generated by solar flares should allow them to verify independently some of the conditions in the solar interior that they have inferred from studying the pattern of waves that are continually ruffling the Sun's surface. SOHO is part of the International Solar-Terrestrial Physics (ISTP) program, a global effort to observe and understand our star and its effects on our environment. The ISTP mission includes more than 20 satellites, coupled with with ground-based observatories and modeling centers, that allow scientists to study the Sun, the Earth, and the space between them in unprecedented detail. ISTP is a joint program of NASA, ESA, Japan's Institute for Astronautical Science, and Russia's Space Research Institute.

Title Loop of AMSR-E Daily Arctic Sea Ice from Aug 2005 to Aug 2006
Abstract Sea ice is frozen seawater floating on the surface of the ocean. Some sea ice is permanent, persisting from year to year, and some is seasonal, melting and refreezing from season to season. Sea ice is almost always in motion, reacting to ocean currents and to winds. The AMSR-E instrument on the Aqua satellite acquires high resolution measurements of the 89 GHz brightness temperature near the poles. Because this is a passive microwave sensor and independent of atmospheric effects, this sensor is able to observe the entire polar region every day, even through clouds and snowfalls. This animation of AMSR-E 89 GHz brightness temperature in the northern hemisphere during late 2005 and early 2006 clearly shows the dynamic motion of the ice as well as its seasonal expansion and contraction. This animation shows the seasonal advance and retreat of sea ice over the Arctic from 8/5/2005 through 8/4/2006. The false color of the sea ice, derived from the AMSR-E 6.25 km 89 GHz brightness temperature, highlights the fissures in the sea ice by showing warmer areas of ice in a deeper blue and colder areas of sea ice in a brighter white. The sea ice extent is defined by a three-day moving average of the AMSR-E 12.5 km sea ice concentration, showing as ice all areas having a sea ice concentration greater than 15%.

Title Snow Cover over the Northern Hemisphere during the Winter of 2002-2003 (WMS)
Abstract The amount of snow covering the land has both short and long term effects on the environment. From season to season, snow coverage and depth affect soil moisture and water availability, which directly influence agriculture, wildfire occurrences, and drought. In the long term, the part of the Earth's surface covered by snow reflects up to 80 or 90 percent of the incoming solar radiation as opposed to the 10 or 20 percent that uncovered land reflects, and this has important consequences for the Earth's climate. Satellites identify the snow cover precisely by looking at the difference between light reflected off snow in the visible and the infrared wavelengths. This visualization shows the snow cover in the Northern Hemisphere from September, 2002, through June, 2003, as measured by the MODIS instrument on the Terra satellite. Since this instrument cannot measure snow cover through clouds, this visualization designates an area as covered by snow when the instrument takes a valid measurement showing greater than 50% snow coverage in that area. This area is assumed to be snow covered until the instrument takes a valid measurement showing less than 40% snow coverage in that same area. It is possible to see topographic features in the snow cover such as the Rocky Mountains and the Himalayas, and large snow coverage paths from storms that cross the plains of the United States and Russia can also be seen.

Earth At Night (WMS)
Title Earth At Night (WMS)
Abstract This image of Earth's city lights was created with data from the Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS). Originally designed to view clouds by moonlight, the OLS is also used to map the locations of permanent lights on the Earth's surface. The brightest areas of the Earth are the most urbanized, but not necessarily the most populated. (Compare western Europe with China and India.) Cities tend to grow along coastlines and transportation networks. Even without the underlying map, the outlines of many continents would still be visible. The United States interstate highway system appears as a lattice connecting the brighter dots of city centers. In Russia, the Trans-Siberian railroad is a thin line stretching from Moscow through the center of Asia to Vladivostok. The Nile River, from the Aswan Dam to the Mediterranean Sea, is another bright thread through an otherwise dark region. Even more than 100 years after the invention of the electric light, some regions remain thinly populated and unlit. Antarctica is entirely dark. The interior jungles of Africa and South America are mostly dark, but lights are beginning to appear there. Deserts in Africa, Arabia, Australia, Mongolia, and the United States are poorly lit as well (except along the coast), along with the boreal forests of Canada and Russia, and the great mountains of the Himalaya.

Title Seasonal Landcover Change over Eastern Asia in 2004
Abstract The Blue Marble Next Generation dataset provides a monthly global cloud-free true-color picture of the Earth's landcover at a 500-meter spatial resolution. This visualization of the dataset shows seasonal variations such as snowfall, spring greening and droughts in a seamless fashion, thereby heightening awareness of changes in the Earth's climate. Here we focus on the seasonal landcover changes over the Eastern Asia. This dataset is derived from imagery taken in 2004 by the MODIS instrument on the Terra satellite.

Name of Image STS-102 Mission Crew Insignia
Date of Image 2001-01-01
Full Description This is the STS-102 mission crew insignia. The central image on the crew patch depicts the International Space Station (ISS) in the build configuration that it had at the time of the arrival and docking of Discovery during the STS-102 mission, the first crew exchange flight to the Space Station. The station is shown along the direction of the flight as was seen by the shuttle crew during their final approach and docking, the so-called V-bar approach. The names of the shuttle crew members are depicted in gold around the top of the patch, and surnames of the Expedition crew members being exchanged are shown in the lower barner. The three ribbons swirling up to and around the station signify the rotation of these ISS crew members. The number 2 is for the Expedition 2 crew who flew up to the station, and the number 1 is for the Expedition 1 crew who then returned down to Earth. In conjunction with the face of the Lab module of the Station, these Expedition numbers create the shuttle mission number 102. Shown mated below the ISS is the Italian-built Multipurpose Logistics Module, Leonardo, that flew for the first time on this flight. The flags of the countries that were the major contributors to this effort, the United States, Russia, and Italy are also shown in the lower part of the patch. The build-sequence number of this flight in the overall station assembly sequence, 5A.1, is captured by the constellations in the background.
