Hurricane Emily and Luna

This unusual high-oblique (from the side) panoramic view of the eye of Hurricane Emily in 2005 was shot by the crew of the International Space Station while they passed over the southern Gulf of Mexico looking eastward toward the rising moon. The eye appears as a depression in the cloud deck, which stretches out to the horizon and fades into the limb (the bright blue cross-section) of the Earth’s atmosphere. At the time this image was taken, Emily was a strengthening Category 4 hurricane with wind speeds approaching 155 miles per hour. The hurricane was moving west-northwest over the northwest Caribbean Sea about 135 miles southwest of Kingston, Jamaica.

Searles Lake, California

Searles Lake is known for the abundance of rare elements and evaporate minerals, such as trona, hanksite, and halite formed within its sediments. Evaporites are minerals that are left behind when saltwater evaporates. This astronaut photograph depicts the Searles Lake playa (characterized by white surface mineral deposits) bounded by the Argus and Slate Mountains. The width of the playa is approximately 10 kilometers. The center of the image is dominated by mining operations that extract sodium- and potassium-rich minerals (primarily borax and salt) for industrial use.

Las Cruces, New Mexico

The city of Las Cruces is located within the Rio Grande Rift, a large geological feature that extends from Colorado southwards into Mexico. The Rio Grande Rift is marked by a series of depressions punctuated with uplifted mountains. Sinking in one place is often accompanied by uplift along boundaries of the grabens—the striking Organ Mountains to the east of Las Cruces are one such uplifted fault block.

Sept-îles, Gulf of St Lawrence, Quebec, Canada

Seven Island Bay (left side of the image) is one of the largest and best-protected harbors on Quebec’s north shore of the Gulf of St. Lawrence. Because this is both a deep-water port and ice-free year round, Sept-Îles is one of Quebec’s busiest ports. Locally produced materials (iron ore, alumina) comprise the bulk of port traffic, but Sept-Îles also acts as a trans-shipment point for goods moving to Europe, the Far East, and South America.

Port of Rotterdam, Netherlands

The Port of Rotterdam, also known as Europoort (Eurogate), has been an important trading center since approximately AD 1250. The history of the port reflects the evolution of the world’s economic base. Originally serving the North Sea herring fleets, it rapidly grew into a major mercantile port during the Dutch colonial period. The 19th century witnessed the Industrial Revolution, and steel and coal became major commodities passing through the port. Following the development of petroleum as a primary energy resource in the early 20th century, the port expanded westward to accommodate storage facilities and large oil tankers.

Fire Scars in Australia’s Simpson Desert

Bright orange fire scars show up the underlying dune sand in the Simpson Desert, 300 kilometers east of Alice Springs, in this astronaut photograph taken from the International Space Station in November, 2003. The fire scars were produced in a recent fire, probably during the same year. The image suggests a time sequence of events. Fires first advanced into the view from the lower left—parallel with the major dune trend and dominant wind direction. Then the wind shifted direction by about 90 degrees so that fires advanced across the dunes in a series of frond-like tendrils.

Ural River Delta, Kazakhstan
Image

Ural River Delta, Kazakhstan

The Ural River is one of the two major rivers (the other is the Volga) that empty into the northern coast of the Caspian Sea, creating extensive wetlands. This image shows details of the Ural’s tree-like (or “digitate”) delta. This type of delta forms naturally when wave action is low, and sediment content in the river is high. New distributary channels form in the delta when the river breaches natural levees created by sediment deposition. The long main channel of the river in this image and several of the distibutary channels are too regular to be entirely natural, however. Like the famous Mississippi River delta in the United States, the Ural River delta has been significantly modified to reduce flooding and divert water.

Tarbela Dam, Pakistan

The Indus River basin extends from the Himalaya Mountains that form the northeastern boundary of Pakistan to the alluvial plains of Sindh near the Arabian Sea coastline. Tarbela Dam is part of the Indus Basin Project, which resulted from a water treaty signed in 1960 between India and Pakistan. This treaty guaranteed Pakistan water supplies independent of upstream control by India. Designed primarily for water storage rather than power generation, the dam was completed in 1977. Turquoise waters of the Indus River (to the south of the dam) reflect the high proportion of silt and clay suspended in waters released by the spillways.

Khartoum, Sudan
Image

Khartoum, Sudan

Sudan’s capital city, Khartoum, translates as “Elephant’s Trunk.” The name describes the shape of the Nile where the Blue and the White Nile Rivers unite to form the single Nile River that flows northward into Egypt. This image shows the rivers near the end of the dry season. The White Nile (western branch) runs through Sudan from Uganda. It originates in equatorial regions, where rainfall occurs throughout the year, and as a result it runs at a nearly constant rate throughout the year. The Blue Nile, nearly dry this time of year, flows out of the Ethiopian highlands, where rainfall is more seasonal. It swells in the late summer and early fall with rains from the summer monsoons. The flow at these times can be so great that the volume is too much for the river’s channel, causing the Nile to flow backward at the junction.

Jericho, West Bank

Commonly known as “the oldest city in the world,” Jericho is an important historical, cultural, and political center located northwest of the Dead Sea. This astronaut photograph illustrates the city center, and the original settlement mound of Tell es-Sultan. Total distance across the image is approximately 8 kilometers (5 miles). Two large refugee camps are located to the northwest and south of the city center. The high building density of the refugee camps contrasts sharply with the more open city center and irrigated fields (green polygonal patches) of Jericho, and illustrates one of the physical consequences of the ongoing Israeli-Palestinian conflict in the region.

International Space Station Astronaut Leroy Chiao, like the rest of NASA, tracks key milestones for the Space Shuttle Return-to-Flight operations. A lucky overpass of the Space Station over Florida on April 6, 2005, allowed Leroy and his crew mate Salizhan Sharipov a unique view of the rollout of the Space Shuttle Discovery. At the time of his observations, Discovery was approximately midway between the Vehicle Assembly Building (VAB) and launch pad 39-B at Kennedy Space Center in Florida.

Mount Olympus is the highest peak in Greece. The 2,917-meter (9,570-foot) summit is the tallest in a mountain chain that runs north into Bulgaria and south into Turkey, via the Cyclades Islands. In this winter view, Olympus is the only peak with a dusting of snow—perhaps the reason its name in classical Greek means “the luminous one.” In Greek mythology, the peak was inhabited by the Twelve Olympians, the most famous gods of the ancient Greeks. North of Mount Olympus lies Macedonia, the homeland of Alexander the Great. Climbing the famous mountain is a favorite tourist activity today.

Following the last major upheaval of the Andes Mountains, rivers flowing down into the Pacific Ocean have carved dramatic canyons along Peru’s southern coast. In geologic terms, the canyons are relatively young—carved over the past 8 million years. This oblique (off-vertical) image from March 14, 2003, provides a southward look down Peru’s rugged, arid coastline between 15.5 and 17 degrees South latitude. The canyons run from left to right and appear grayer than the surrounding reddish-brown terrain.

Fringing Coral Reef, Red Sea

The Sudanese coast of the Red Sea is a well-known destination for diving due to clear water and abundance of coral reefs (or shia’ab in Arabic). Reefs are formed primarily from precipitation of calcium carbonate by corals. (In addition to its commonly used meaning, precipitation can also describe how something dissolved in a solution becomes “undissolved” through chemical or biological processes.) Massive reef structures are built over thousands of years of succeeding generations of coral. In the Red Sea, fringing reefs form on shallow shelves of less than 50 meters depth along the coastline. This astronaut photograph illustrates the intricate morphology of the reef system located along the coast between Port Sudan to the northwest and the Tokar River delta to the southeast.

The city of Shenyang is China’s sixth largest city with a population ofover 4 million residents in the urban core. The city is the major industrial, commercial, and cultural center of northeastern China (the region historically known as Manchuria). Its geographic location on the flood plains of the Hun and Liao Rivers ensured an early agrarian economy that was later replaced by industrialization and natural resource extraction. The major portion of the local economy is devoted to industries such as metal smelting, coal mining, and petrochemical processing. Several southeast-trending plumes from industrial facilities are visible in the image.

Located approximately 50 kilometers northeast of Tehran, Mt. Damavand is an impressive stratovolcano that reaches 5,670 meters (18,598 feet) in elevation. Part of the Alborz Mountain Range that borders the Caspian Sea to the north, Damavand is a young volcano that has formed mostly during the Holocene Epoch (over approximately the last 10,000 years). The western flank of the volcano includes solidified lava flows with flow levees—“walls” formed as the side edges of flowing lava cooled rapidly, forming a chute that channeled the hotter, interior lava. Two such flows with well-defined levees are highlighted by snow on the mountainside.

Solimões-Negro River Confluence at Manaus, Amazonia

The largest river on the planet, the Amazon, forms from the confluence of the Solimões (the upper Amazon River) and the Negro at the Brazilian city of Manaus in central Amazonas. At the river confluence, the muddy, tan-colored waters of the Solimões meet the “black” water of the Negro River. The unique mixing zone where the waters meet extends downstream through the rainforest for hundreds of kilometers, and is a famous attraction for tourists from all over the world. The tourism contributes to substantial growth in the city of Manaus. Twenty years ago the large park near the city center (center) lay on the eastern outskirts of Manaus.
