Sangeang Api, Indonesia

In 1985, the small Indonesian island of Sangeang Api (13 kilometers 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 by Space Shuttle astronauts in 2002. Today, the island’s summit crater (1949 m) produces intermittent steam clouds.

Astronaut Photos of Hurricane Lili

On October 2, 2002, Houston’s Mission Control Center powered down and people along the coasts of Texas and Louisiana prepared for landfall of Hurricane Lili. The storm held special significance for International Space Station astronauts orbiting above 210 n. mi. above—it delayed that day’s launch of the Space Shuttle that was scheduled to bring them visitors and supplies and hardware. However, the crew gained perspective on Lili by tracking and photographing the hurricane near its peak.

Easter Island

On September 25, 2002, astronauts aboard the International Space Station viewed Easter Island, one of the most remote locations on Earth. Easter Island is more than 2000 miles from the closest populations on Tahiti and Chile—even more remote than astronauts orbiting at 210 nautical miles above the Earth. Archaeologists believe the island was discovered and colonized by Polynesians at about 400 AD. Subsequently, a unique culture developed. The human population grew to levels that could not be sustained by the island. A civil war resulted, and the island’s deforestation and ecosystem collapse was nearly complete.

Mount Kazbek, Caucasus, Russia

This photograph of Mt. Kazbek was taken from the International Space Station on August 13, 2002. The astronauts and cosmonauts took the photograph at the request of the Russian URAGAN project, which is studying changes in the world’s glaciers in response to global climate change. Although scientists have predicted the possibility of large glacial collapses as the climate warms, no one predicted that tragedy would strike the mountain village of Karmadon, a little more than a month later.

Hakodate City is a seaport located on two bays in the Oshima Peninsula near the south end of the major Japanese island of Hokkaido. This image nicely illustrates how sunglint reflecting off the ocean reveals internal waves impinging on the coast. Also, from space, Hakodate is quite distinguished from other cities of it size, featuring a large five-pointed star near it center.

Kanaga Volcano, Alaska

The symmetrical cone of Kanaga volcano stands out on the northern corner of Kanaga Island, located in the central part of Alaska’s Aleutian archipelago. Kanaga last erupted in 1994 and is well known for its active fumaroles and hot springs (located, in this image, by fine steam plumes on the northeast flank of the volcano). A small lake to the southeast of the cone is situated on the floor of a larger more ancient volcanic caldera. The crew of the international space station acquired this image late in the day of August 13, 2002. Note how the late summer sun accentuates the terrain features like the volcanic flows that radiate down from the volcano’s peak, and the steep cliffs along the western coastline.

Petroleum Infrastructure, Denver City, Texas

Agriculture and the petroleum industry compete for land use near Denver City, Texas, southwest of Lubbock near the New Mexico border. The economy of this region is almost completely dependent on its underground resources of petroleum and water. Both resources result in distinctive land use patterns visible from space. Historically this area has produced vast quantities of oil and gas since development began in the 1930s. Note the fine, light-colored grid of roads and pipelines connecting well sites over this portion of the Wasson Oil Field, one of the state’s most productive. Since the 1940s, agricultural land use has shifted from grazing to irrigated cultivation of cotton, sorghum, wheat, hay, and corn. The water supply is drawn from wells tapping the vast, but failing, Ogallala Aquifer. Note the large, circular center-pivot irrigation systems in the lower corners of the image. The largest is nearly a mile in diameter.

Contrail Web over the Central Rhône Valley, Eastern France

This digital photograph taken through the windows of the International Space Station on May 15, 2002, shows condensation trails over the Rhône Valley in the region west of Lyon. Condensation trails—or contrails—are straight lines of ice crystals that form in the wake of jet liners where air temperatures at altitude are lower than about 40°C. Newer contrails are thin whereas older trails have widened with time as a result of light winds. Because of this tendency for thin contrails to cover greater areas with time, it is estimated that these “artificial clouds” cover 0.1% of the planet”s surface. Percentages are far higher in some places such as southern California, the Ohio River Valley and parts of Europe, as illustrated here.

Fernandina Island, Galapagos

La Cumbre volcano on Fernandina Island is the most active volcano on the Galapagos, erupting most recently in 1995. The volcano rises 1495 m from sea level. This photo was taken by the Expedition 5 crew aboard the International Space Station. The scene provides a detailed view of the 850-m-deep summit caldera. The dark flows in the middle of the caldera floor were erupted in 1991. Today, these flows are partly covered by dark green vegetation.

Summit Crater of Mauna Loa

Mauna Loa is the largest volcano on our planet—the summit elevation is 4,170 m (over 13,600 ft), but the volcano’s summit rises 9 km above the sea floor. The sharp features of the summit caldera and lava flows that drain outward from the summit are tribute to the fact that Mauna Loa is one of the Earth’s most active volcanoes. The most recent eruption was in 1984. The straight line the cuts through the center of the crater from top to bottom is a rift zone—an area that pulls apart as magma reaches the surface.

New Cornelia Mine, Arizona

Although this photograph may appear to be a small pit mine as seen from the air, it is actually a pit mine that is about a mile wide and just over a thousand feet deep as photographed by astronauts orbiting the Earth on board the International Space Station. The New Cornelia Mine is located just south of Ajo, Arizona. Small-scale mining of copper in this area began with the Spaniards and Mexicans as early as 1750. This large-scale, systematic operation began in 1912 and expanded rapidly for the next 50 years. Since the mid 1980s, activity has been limited because of low prices for copper on the world market. Note the tailings deposits to the east (right) and the larger containment ponds for extraction processes to the northeast.

Egmont National Park, New Zealand

The lush forests of Egmont National Park, on New Zealand‘s North Island, contrast with the pasturelands outside the circular park boundaries. The unique shape of the park results from its first protection in 1881, which specified that a forest reserve would extend in a 9.6-kilometer radius from the summit of Mt. Taranaki (named Mt. Egmont by Captain Cook). The park covers about 33,500 hectares and Mt. Egmont stands 2518 meters tall. The volcano began forming 70,000 years ago, and last erupted in 1755. A series of montane habitats occur in procession up the flanks of the volcano—from rainforest, to shrubs, to alpine, and finally snow cover.

San Francisco Bay

Astronauts aboard the International Space Station (ISS) took this photograph of the San Francisco Bay area in April, 2002. The gray urban footprint of San Francisco, Oakland, San Jose, and their surrounding suburbs contrast strongly with the green hillsides. Of particular note are the Pacific Ocean water patterns that are highlighted in the sun glint. Sets of internal waves traveling east impinge on the coastline south of San Francisco. At the same time, fresher bay water flows out from the bay beneath the Golden Gate Bridge, creating a large plume traveling westward. Tidal current channels suggest the tidal flow deep in thebay. Because the ISS orbits are not synchronous with the sun, astronauts view the Earth with variable solar illumination angles. This allows them to document phenomena such as the sun reflecting differentially off surface waters in a way that outlines complicated water structures.

Thunderstorms over Brazil

This photograph, acquired in February 1984 by an astronaut aboard the space shuttle, shows a series of mature thunderstorms located near the Paraná River in southern Brazil. With abundant warm temperatures and moisture-laden air in this part of Brazil, large thunderstorms are commonplace. A NASA-funded researcher has discovered that tiny airborne particles of pollution may modify developing thunderclouds by increasing the quantity and reducing the size of the ice crystals within them. These modifications may affect the clouds’ impact on the Earth’s “radiation budget,” or the amount of radiation that enters and leaves our planet.
