Aldabra Islands, Indian Ocean (November 1991)

STS044-082-057

The islands of Aldabra and Assumption, part of the Seychelles in the Indian Ocean northwest of Madagascar, appear in this near-vertical photograph. Larger Aldabra, an oval atoll more than 20 miles (32 kilometers) long, encloses a large lagoon. The islands cover 60 square miles (155 square kilometers) and are known for their distinct fauna, particularly the giant land tortoise.

Alexandria, Egypt March 1990

STS036-151-100

The seaport city of Alexandria, with a population of more than 3.5 million, is built primarily on a sandy strip of land between the Mediterranean Sea and Lake Mareotis. An industrial and commercial city, Alexandria anchors the western extent of the large Nile River Delta. Although most of the city infrastructure is not visible, some of the large modern harbor facilities, including a breakwater structure, are discernible in the small bay. The unusual tan water body southwest of the port facilities is possibly a holding pond for industrial effluents. A narrow band of darker substance in the water current appears to be flowing toward the east, and farther offshore, an interesting light blue turbidity indicates water color boundaries along this part of the Mediterranean Sea. A series of canals and roadways appears within the darker green of the fertile, intensively cultivated and irrigated, agricultural Nile River Delta. Circular field patterns southwest of the city indicate that center-pivot irrigation is being used in addition to irrigation from ditches and canals. The smaller, highly reflective areas scattered among the irrigated farmland are villages and cities.

Amazonas, Brazil (January 1986)

STS61C-33-0084

Two rivers and an urban area dominate this photograph. The largest city in the Amazon Basin, Manaus (with a 1994 population of 1.7 million), is located at the confluence of the Rio Negro (dark blue) and the Amazon River (lighter because of its high sediment content). The combined river flows eastward into the Atlantic Ocean. Situated approximately 800 miles (1290 kilometers) from the mouth of the Amazon River but accessible to oceangoing ships, Manaus is an important river port. This port city started to flourish in the late 1800s when the rubber boom was at its peak. Rubber, Brazil nuts, lumber, and assorted fruits are exported. In recent years, renewed interest in general development and the discovery of oil and manganese near Manaus have brought new importance to the city. A number of highways (linear, light-colored features), as well as a large commercial airport north of the city, are visible in the rain forest north and south of Manaus. North-south ground transportation is hindered because no bridges cross the Rio Negro or Amazon River. A large, sediment-laden lake (note irregular shoreline) is located east of Manaus between the main channel of the Amazon River and a smaller channel to the south.

Antigua, Leeward Islands (September 1994)

STS064-076-0BB

Antigua, a low-lying, semiarid, limestone island of the Lesser Antilles, is part of a two-island independent state, Antigua and Barbuda. Antigua has severely eroded volcanic remnants along its forested southwestern quadrant, which has a maximum elevation of only 1319 feet (402 meters) above sea level. Although Antigua receives approximately 40 inches (100 centimeters) of precipitation annually, wide fluctuations in rainfall amounts occasionally create serious water shortages, especially for the agricultural industry. Some of the larger hotels transport water by barge from nearby islands when water supplies become critically low. At one time Antigua’s economy was based largely on the sugarcane industry, but light manufacturing and tourism are now the leading contributors to the island’s economy. St. John’s, the country’s capital, is located along the northwest coast, adjacent to one of the island’s many natural harbors. More than half of the country’s population of almost 80 000 live in the St. John’s area. The island is approximately 16 miles (25 kilometers) east-west and 12 miles (19 kilometers) north-south.

Atlasova Island, Kuril Islands, Russia (September 1992)

STS047-075-082

This low-oblique, southwest-looking photograph of Atlasova Island shows the classic radial drainage pattern seen in most stratovolcanoes. Atlasova Island is located at the northern end of the Kuril Islands arc about 60 miles (95 kilometers) west of the southern tip of Kamchatka Peninsula, Russia. This island’s summit reaches 7675 feet (2340 meters) above sea level, making it the highest point in the Kuril chain. The other land visible in this photograph is the northern end of Paramushir Island, another volcanic island in the Kuril archipelago. The Kuril Islands are a continuation of the volcanic mountains of Kamchatka Peninsula to the north and the Japanese islands to the south. (Refer to STS-068-231-054 for a view of other Kuril Islands, including Onekotan Island.)
