STS099-753-032 (11-22 February 2000) ---This 70mm photograph, photographed from the Space Shuttle Endeavour, centers on the two westernmost Galapagos Islands--seahorse-shaped Isla Isabela and the smaller round Isla Fernandina to its west. All of the 19 islands in the chain are volcanic in origin, and the craters of several of the shield volcanoes are visible as circular features on each of the islands. The two islands shown in this picture contain the most active volcanoes of the Galapagos. Fernandina last erupted in January-February 1995, with red-hot lava pouring into the sea. After 20 years of inactivity, Cerro Azul on Isla Isabela, last erupted in September-October 1998. Cerro Azul is the southwesternmost volcano on Isla Isabela. At 82 miles long, Isla Isabela is the largest of the islands, and comprises half of the land area of the archipelago. The islands are famous for their unique flora and fauna. Charles Darwin's observations of these species in 1835 contributed to the formation of his ideas on natural selection. Some of the most unique species include flightless cormorants, Galapagos penguins, giant land tortoises, and Galapagos finches. The range of Galapagos penguins is restricted to these western islands where upwelling enriches the ocean productivity, and the adaptation of a typically Antarctic bird family to the equator is an ecological marvel. Giant land tortoises are thought to have the oldest lifespans of any animal on Earth, but, scientists say, they have been driven near to extinction. During the most recent eruption of Cerro Azul, one tortoise was killed and many had to be relocated. The 13 species of Galapagos finches on the islands, although varied in form and lifestyle, are the descendants of an ancestor that happened to colonize this isolated archipelago. The human population of the entire archipelago is about 10,000.

An emperor penguin waddles away on Christmas morning in Antarctica. On Christmas day, the BARREL team visited a penguin colony. Credit: NASA --- In Antarctica in January, 2013 – the summer at the South Pole – scientists launched 20 balloons up into the air to study an enduring mystery of space weather: when the giant radiation belts surrounding Earth lose material, where do the extra particles actually go? The mission is called BARREL (Balloon Array for Radiation belt Relativistic Electron Losses) and it is led by physicist Robyn Millan of Dartmouth College in Hanover, NH. Millan provided photographs from the team’s time in Antarctica. The team launched a balloon every day or two into the circumpolar winds that circulate around the pole. Each balloon floated for anywhere from 3 to 40 days, measuring X-rays produced by fast-moving electrons high up in the atmosphere. BARREL works hand in hand with another NASA mission called the Van Allen Probes, which travels through the Van Allen radiation belts surrounding Earth. The belts wax and wane over time in response to incoming energy and material from the sun, sometimes intensifying the radiation through which satellites must travel. Scientists wish to understand this process better, and even provide forecasts of this space weather, in order to protect our spacecraft. As the Van Allen Probes were observing what was happening in the belts, BARREL tracked electrons that precipitated out of the belts and hurtled down Earth’s magnetic field lines toward the poles. By comparing data, scientists will be able to track how what’s happening in the belts correlates to the loss of particles – information that can help us understand this mysterious, dynamic region that can impact spacecraft. Having launched balloons in early 2013, the team is back at home building the next set of payloads. They will launch 20 more balloons in 2014. <b><a href="http://www.nasa.gov/audience/formedia/features/MP_Photo_Guidelines.html" rel="nofollow">NASA image use policy.</a></b> <b><a href="http://www.nasa.gov/centers/goddard/home/index.html" rel="nofollow">NASA Goddard Space Flight Center</a></b> enables NASA’s mission through four scientific endeavors: Earth Science, Heliophysics, Solar System Exploration, and Astrophysics.

ISS011-E-12147 (26 Aug. 2005) --- South Georgia Island is featured in this image photographed by an Expedition 11 crewmember on the International Space Station. There is no permanent human base on South Georgia Island, a British territory in the South Atlantic Ocean that lies 1300 kilometers east of the Falkland Islands. Using a long lens (800 mm focal length) and positioned for an oblique view, the crew of the international space station was able to capture the rugged and isolated landscape of the northern shore of the island. The high mountains protect the north and eastern coast of the island from the prevailing gales coming from Antarctica and the west. The steep topography also makes deep embayments along the coast that provide habitat for wildlife and anchorages for whaling ships. The island supports major rookeries of penguins and albatrosses, and large seal populations. This view centers on Mt. Paget and Cumberland Bay. The former whaling station Grytviken is located within the bay. The encampment supports the scientific base for the British Antarctic Survey and Bird Island Research Station.

KENNEDY SPACE CENTER, FLA. -- At the Kennedy Space Center Visitor Complex, Dr. Norman E. Thagard (left) is inducted into the U.S. Astronaut Hall of Fame. Thagard was the first American to occupy Russia's Mir space station. Former NASA astronaut James A. Lovell Jr. holds a "penguin suit," the clothing Thagard wore aboard Mir. The suit will be put on display in the Hall of Fame. Also chosen for induction in 2004 are Kathryn D. Sullivan, the first American woman to walk in space; Richard O. Covey, commander of the Hubble Space Telescope repair mission; Frederick D. Gregory, the first African-American to command a space mission; and the late Francis R. "Dick" Scobee, commander of the ill-fated 1986 Challenger mission. The U.S. Astronaut Hall of Fame opened in 1990 to provide a place where space travelers could be remembered for their participation and accomplishments in the U.S. space program. To be eligible for induction, an individual must have been a U.S. citizen, a NASA astronaut, and out of the active astronaut corps at least five years. The five inductees join 52 previously honored astronauts from the ranks of the Gemini, Apollo, Skylab, Apollo-Soyuz, and Space Shuttle programs.

ISS034-E-041528 (6 Feb. 2013) --- Tristan da Cunha is featured in this image photographed by an Expedition 34 crew member on the International Space Station. The island is located in the southern Atlantic Ocean; more than 3,700 kilometers from the northern coastline of Antarctica, approximately 2,800 kilometers to the southern tip of Africa, and more than 3,000 kilometers from the eastern coastline of South America. The island forms part of the British Overseas Territory of Saint Helena, Ascension, and Tristan da Cunha. The shoreline of the 13-kilometer-wide island is marked on most sides by steep cliffs, with lower beach areas on the southern and north-northwestern sides. The island is notable for its bird population, including important breeding grounds for a variety of petrels, albatrosses, penguins and shearwaters. Tristan da Cunha is a shield volcano; a type of volcanic structure usually recognized by a low, broad profile and composed of silica-poor lavas (such as basalt). The upper surface of this low base appears dark green in this photograph. Steeper, brown to tan colored slopes mark the central cone of the volcano at the island?s center. The summit crater, Queen Mary?s Peak, sits at an elevation of 2,060 meters above sea level. While geologic evidence indicates that eruptions have occurred from the central crater, lavas have also erupted from flank vents along the sides of the volcano as well as smaller cinder cones. The last known eruption of Tristan da Cunha took place 1961-1962 and forced evacuation of the only settlement on the island, Edinburgh of the Seven Seas. The settlement is located along the northern coastline of the island (obscured by clouds in this image). This is considered to be the most remote permanent settlement on Earth, with its citizen?s nearest neighbors located 2,173 kilometers to the northeast on the island of St. Helena.

Completed: 07-16-2009 Straddling the equator approximately 1000 kilometers to the west of the South American mainland, the Galapagos Islands lie within the heart of the equatorial current system. Rising from the sea floor, the volcanic islands of the Galapagos are set on top of a large submarine platform. The main portion of the Galapagos platform is relatively flat and less than 1000 meters in depth. The steepest slopes are found along the western and southern flanks of the platform with a gradual slope towards the east. The interactions of the Galapagos and the oceanic currents create vastly different environmental regimes which not only isolates one part of the Archipelago from the other but allows penguins to live along the equator on the western part of the Archipelago and tropical corals around the islands to the north. The islands are relatively new in geologic terms with the youngest islands in the west still exhibiting periodic eruptions from their massive volcanic craters.

ISS020-E-039083 (6 Sept. 2009) --- Glacier outlet in the Southern Patagonian Ice Field of Chile is featured in this image photographed by an Expedition 20 crew member on the International Space Station. The Southern Patagonian Ice Field of Chile and Argentina hosts a spectacular array of glaciers and associated glacial features within the southern Andes Mountains. Glaciers flowing downhill on the eastern side of the mountains have outlets into several large freshwater lakes. On the western side of the mountains, glaciers release ice into the Pacific Ocean via an intricate network of fjords. Fjords are steep valleys originally cut by glaciers during periods of lower sea level that are now inundated. As glaciers flow into the fjord, ice at the front of the glacier begins to break off and form icebergs that can float out to sea ? a process known as calving. This detailed photograph shows the merged outlet of Penguin Glacier and HPS 19 into a fjord carved into the snow-covered mountains of the southern Andes. The designation HPS stands for Hielo Patagonico Sur (e.g. Southern Patagonian Ice field) and is used to identify glaciers that have no other geographic name. Ice flowing into the fjord begins to break up at center, forming numerous icebergs ? the largest visible in this image is approximately 2 kilometers in width. The large ice masses visible at center have a coarse granular appearance due to variable snow cover, and mixing and refreezing of ice fragments prior to floating free.

ISS030-E-193144 (25 March 2012) --- Wave clouds near Ile aux Cochons are featured in this image photographed by an Expedition 30 crew member on the International Space Station. This photograph illustrates the formation of wave clouds in the wake—or downwind side—of Ile aux Cochons (“Isle of Pigs”) located in the Southern Indian Ocean. The island is approximately located 3,000 kilometers southeast of the southern tip of the African continent and 2,300 kilometers northwest of Antarctica. The island itself, of which only a part of the eastern coastline is visible at center, is volcanic in origin with a summit elevation of 775 meters above sea level. According to scientists, the Ile aux Cochons stratovolcano is thought to have erupted within the last 12,000 years; however no historical activity has been recorded. The summit elevation is high enough for the land surface to interact with cloud layers and winds flowing past the island. Two major cloud layers are visible; a lower, more uniform layer consists of roughly parallel cloud “streets” that suggest a westerly flow pattern of air. When the air mass encounters the Ile aux Cochons, moisture-laden air rises and cools, causing more water vapor to condense into clouds. As the air mass passes over the summit of Ile aux Cochons and descends, it may encounter alternating moist and dry air layers, enabling the formation of the discontinuous chevron-shaped wave clouds in the wake of the island. While their appearance suggests that the clouds are forming in the wake of the island and moving eastwards, in fact it is the air mass that is moving, with clouds forming in regions of moist air and dissipating in dry regions. Ile aux Cochons is the westernmost of the islands that form the subantarctic Crozet Archipelago (part of the French Southern and Antarctic Lands). Accept for occasional research visits, the island is uninhabited. The island is an important breeding site for seabirds, including the world’s largest King Penguin colony.

ISS018-E-018110 (6 Jan. 2009) --- Kerguelen Kelp Beds in the Southern Indian Ocean are featured in this image photographed by an Expedition 18 crewmember on the International Space Station. MacMurdo and Howe Islands are two of the 300 islands of the Kerguelen Archipelago, a remote place located in the Southern Indian Ocean that belongs to the French Southern and Antarctic Lands. The Kerguelen Archipelago is also known as the "Desolation Islands". The coastal regions of the islands support low vegetation (mainly genus Acaena), while elevations above 50 meters are rocky. There are no permanent inhabitants of the islands, but there is a permanent settlement (Port aux Francais) that hosts scientists mainly interested in biology, oceanography and earth sciences ? in addition, the settlement maintains a weather station and satellite/rocket tracking station. Latitudinal weather conditions are typical from the ?roaring forties? through the ?furious fifties? - on the day this image was taken, the mean daily temperature was 4.5 degrees Celsius with mean westerly winds of 9 meters per second. A substantial proportion of the coastlines of sub-Antarctic islands, like the Kerguelen Islands, are occupied by highly productive giant kelp beds (Macrocystis pyrifera). One of the largest marine macroalgaes, the species can grow up to 50 meters in length, forming undersea forests in hard-bottom subtidal areas. Fronds can spread out to form a canopy which can totally cover the water surface ? we interpret that the black patches surrounding coastal areas in this astronaut photograph are the offshore kelp beds. These forests serve as a habitat for marine fauna, and due to their large biomass and relatively long turnover act as an efficient sink for atmospheric carbon dioxide. The surface wave pattern traveling southeastward along the gray-blue ocean surface, and through the kelp beds, are visible due to the sunglint from the water surface. This also improves the identification of the kelp beds by creating a different water texture (and therefore a contrast) between the dark vegetation and the ocean surface. Kerguelen Archipelago hosts thousands of marine birds (penguins, albatrosses, and petrels among others) and seals (elephant and Antarctic fur species). Whales (humpback) and dolphins (killer whales and Commerson's dolphin) are very common in the area. Fishing boats also frequent the Archipelago ? including unlicensed, so-called ?pirate? fishing vessels.
