Mining and Agriculture in Kazakhstan: Agricultural activities and mining occur side-by-side in the Republic of Kazakhstan. This scene is located in the Turgayskaya Oblast of central Kazakhstan, near the provincial capital of Arkalyk, where Russian spacecraft landings occur. The large, mostly square fields are probably spring wheat, one of the cereal grains that grows well in the cold, dry climate. The colorful, irregular patterns on the left side of the image appear to be surface-mining operations where water has accumulated to form small lakes. Bauxite and asbestos are the principal minerals extracted in this region.

Constanta, Romania: The modern city of Constanta, with a population of more than 348,000, is located on the western coast of the Black Sea and is the principal seaport for Romania. It is the site of the ancient Greek city of Tomis, colonized in the 6th century B.C. In the 1st century A.D. Tomis became a flourishing provincial capital of the Roman Empire when it acquired its current name from the emperor Constantine I. Today, Constanta is a thriving port-of-entry for Romania, offering both tourist attractions and an expanding, modern port facility that is among the largest on the Black Sea. The crew of STS-112 acquired this detailed digital image of the city on October 17, 2002, using a 400-mm lens. The older part of the city is situated near the large coastal lagoon to the north, while to the south the port facilities are connected to the Danube River’s import shipping commerce via the 64-km Danube – Black Sea Canal. Agricultural fields of mostly wheat and barley extend almost to the shorelines.

Space Shuttle view after Kolka Glacier Collapse: While docked to the Space Station the international crew of Space Shuttle Mission STS-112 paused as the spacecraft sped over the Caucasus Range. They had planned before launch that a crewmember would look out the windows of the spacecraft for remnants of the disastrous collapse of Kolka Glacier. The close collaboration between the USA and Russia on all aspects of Space Station construction, and the presence on the Shuttle crew of Russian mission specialist Fyodor Yurchikhin, made the crew particularly interested in photographing the area to help scientists on the ground in their studies of the collapse.

There is a dramatic difference between this digital photograph taken by the Shuttle crew and one taken just a week before the collapse by the International Space Station crew. The debris from Kolka glacier obscures and covers the terminus of Maili glacier. The far northern path of the Genaldon River is filled with debris, compared to the clear river course that could be seen before.

The disaster claimed an estimated 140 lives when it sent 20 million tons of ice, rock and mud down Karmadon Gorge on September 20, 2002. The debris field stretches over 11 miles long (see ASTER images) of the full extent of the debris field) and 820 feet wide, and according to the New York Times, will take as long as 10 years to thaw.

Sangeang Api, Indonesia: In 1985, the small Indonesian island of Sangeang Api (for scale, the island is 13 km wide) off the northeast coast of Sumbawa began to erupt. Within a month, the 1250 inhabitants had evacuated to Sumbawa. The eruption lasted until 1988. The lava and pyroclastic flows—the wide channel running west from the summit—are still easily traced on this image taken last week by Space Shuttle astronauts (STS-112) . Today, the island's summit crater (1949 m) produces intermittent steam clouds.

Compare this photograph to an earlier Space Shuttle photograph taken in November 1985.

Sinai peninsula: Egypt's triangular Sinai Peninsula lies in the center of the view, with the dark greens of the Nile delta lower right. In this SSW-looking view the Red Sea, with its characteristic parallel coastlines, stretches toward the top. At the bottom of the view the Suez Canal appears as an irregular line joining the Red Sea to the Mediterranean Sea (lower left). The Dead Sea in central Israel, with its light blue salt ponds at the south end, appears on the left margin.

Volcanoes of the Northwest: Green colors of the forests of the Cascade Mts dominate the view. Browner colors top right are the semiarid plains of the Columbia Basin, in the rainshadow of the Cascades (north is towards the top left corner). The highest peaks in this part of the Cascades are four volcanoes. The amount of snow is a good indication of their altitude. The highest is Mt Rainier (14,710 feet) with the greatest amount of white snow (top left). Seattle lies immediately downslope (top left margin). Mt Adams (12,276) lies due south in the middle of the view. Mt Hood (11,235 feet) in the lower right corner, lies south of the great gorge of the Columbia River (which crosses the lower right and then the lower left corners of the view). The river flows broadly west (left) to the Pacific Ocean (out of the picture left).

Mt St Helens (8364 feet), the snowfree brown patch lower left, was too low to retain snow after the recent fall. Even from the altitude of the Space Shuttle, the intact south half of the cone can be discerned: the famous blast of 1980 not only destroyed the north side of the cone but blew down the green forest for many square miles on the north side (brown signature).

Bahamas: The light-blue region in the middle of the view is the shallow flat platform (covered by less than 100 feet of water) known as the Great Bahama Bank. Andros Island, the biggest island in the Bahamas chain, is the highest part of this platform and appears partly under cloud in the center of the view. The edges of the platform are steep, dropping off thousands of feet into the ocean depths, the deepest water indicated by deep blues. The 50-mile-wide Strait of Florida is the deep water along the left and lower sides of the view. The Key Largo part of the Florida Peninsula appears in the extreme lower left.

Western USA beneath vertical stabilizer: The Colorado River snakes across this view from top left (near the Space Shuttle stabiliser), to the lower right, where the Grand canyon gorge can be detetced. The wider blue parts of the Colorado in the center of the view are Lake Powell, an artificial lake more than 120 miles long. The dark green areas are wooded slopes generally above ~6000 feet-the Kaibab Plateau (lower left) and the range with Abajo Peak (11,360 feet, Utah-Colorado border region) cross the top of the view. The red areas are lower and semiarid, dominated by desert scrub vegetation.

Rocky Mts Colorado, Utah, Wyoming and Idaho: The Front Range of the Rockies is the dark range crossing the bottom of the view, with Denver and neighboring cities (grays) situated in the gentle embayment of the mountains (bottom center of the view). Great Salt Lake in Utah appears as two colors of blue top left, with the snow-covered Uinta Mts just below, in this NW-looking view. Most of the view encompasses the brown plains of western Wyoming (center) and the cluster of mountains around Yellowstone (top center, top right, with snow). Beyond the brown Snake River Plain, black rocks of the Sawtooth Mts and neighboring ranges of central Idaho appear top center.
