Classroom in Space
Published January 25, 2003
The above photo of the International Space Station was taken by an astronaut aboard the space shuttle on April 17, 2002. Although its construction is not yet complete, Space Station Alpha began operations in November 2000. It now serves as home to three astronauts as well as dozens of already ongoing science experiments.

Baltimore with a Dusting of Snow
Published January 19, 2003
While traveling to the International Space Station aboard the Space Shuttle Endeavor, astronauts photographed the northeastern United States blanketed in fresh snow. This image, taken in early December 2002, shows the city of Baltimore and the surrounding area. An inset shows the center of the city (rotated so north points up).

Kharg Island, Iran
Published January 12, 2003
Kharg Island is Iran’s primary oil export terminal in the Persian Gulf. This rocky limestone island is unique because it is one of the few islands in the Persian Gulf with freshwater which has collected within the porous limestone. In addition to its commercial and strategic importance, the freshwater has biological importance, supporting populations of gazelles. This high-resolution photograph taken by astronauts on board the International Space Station shows detail of the tanker dock facilities, tanks and other infrastructure. Sunglint on the surface of the water highlights small amounts of oil on the sea surface and reveals the direction of the local currents.

Plankton Blooms, Capricorn Channel
Published December 29, 2002
This image captures a plankton bloom in the Capricorn Channel off the Queensland coast of Australia. The whispy pattern of the bloom suggests that the plankton are Trichodesmium—a photosynthetic cyanobacteria, also called “sea saw dust” that is common in the world’s oceans. Trichodesmium is frequently observed around Australia this time of year. In fact, Captain Cook’s ship logs written while he was sailing in Australian waters in the 1700s contain detailed descriptions of Trichodesmium blooms. Astronauts frequently photograph large plankton blooms during their missions because a significant portion of the ISS orbits cross long stretches of ocean. In the process, astronauts become acute observers of subtle changes in sea surface dynamics. Imagery of surface plankton blooms offer multi-dimensional (in space and time) visualizations of the unique physical and chemical circumstances that support the blooms.

Emi Koussi Volcano, Chad, North Africa
Published December 8, 2002
Emi Koussi is a high volcano that lies at the south end of the Tibesti Mountains in the central Sahara in northern Chad. The volcano is one of several in the Tibesti massif, and reaches 3415 m in altitude, rising 2.3 kilometers above the surrounding sandstone plains. The volcano is 65 kilometers wide. This view of the Emi Koussi caldera is detailed to the point that it doesn’t include the entire 10-kilometer diameter of the caldera, but reveals individual lava strata within the walls of the summit cliffs. Nested within the main caldera is a smaller crater that contains white salts of a dry lake at its lowest point. Here too, strata are visible in the walls of the smaller crater. The smaller crater is surrounded by a region of darker rocks—a geologically young dome of lava studded with several small circular volcanic vents.

Mt. Elbrus, Caucasus Range
Published November 10, 2002
The Caucasus Mountains form a long (more than 1200 kilometers) and steep spine connecting the Black Sea to the Caspian. Mt. Elbrus, the summit of the Caucasus Mountains, is located in southern Russia just north of the Georgian border, and is distinguished as Europe’s highest peak (5642 m). Elbrus is also an ancient volcano, although it has not erupted for nearly 2000 years. Elbrus’s profile comprises two volcanic peaks (East and West). They are popular trekking and mountain climbing destinations—the saddle between them provides access to the region. In mid-September, the Russian and American crew aboard the International Space Station viewed Mt. Elbrus’s glaciated landscape as part of a study by Russian glaciologists. Elbrus is located west of the recent glacier slide on Mt. Kazbek, another giant peak in the Caucasus Mountains.

Key West
Published November 3, 2002
Turquoise blue waters, coral reefs and sandy beaches were apparently on the minds of International Space Station astronauts last week. As they passed over the Florida Keys, they acquired a sequence of images from Key West eastward along the outer keys. The detail of the images showcases the clarity of the Caribbean waters, and allows for mapping of both land use and shallow marine features. This image of Key West shows the intensive built-up area of the town, the offshore sand flats and grassbeds surrounding Key West, the patterns of natural tidal channels and artificially dredged channels that allow boat access to the local marinas.

Space Shuttle view after Kolka Glacier Collapse
Published October 27, 2002
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.
Sangeang Api, Indonesia
Published October 20, 2002
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.
