This simulated natural color image shows the Coco River, between Nicaragua and Honduras, as seen from space on December 5, 2002. As it makes its way to the Caribbean Sea, the Coco River forms the border between the two countries. The coastline, known as the Mosquito Coast, is of low relief and has plentiful water bodies, relic shorelines and high temperatures. Mosquito Coast derives its name from its principal inhabitants, the Miskito Indians, whose name was corrupted into Mosquito by European settlers. The Mosquito Indians, of whom there are several tribes, are short in stature and very dark-skinned. The first European settlement in the Mosquito country started in 1630, when agents of the English-chartered Providence Company established friendly relations with the local inhabitants. The image shown covers an area of 29 x 39 kilometers (18 x 24 miles).

Byrd Glacier, Antarctica, is a 15-mile- (24-kilometer-) wide, 100-mile- (161-kilometer-) long ice stream that plunges through a deep valley in the Transatlantic Mountains and into the Ross Ice Shelf. It moves towards the sea at a rate of about half a mile (0.8 kilometers) per year. This snapshot of the glacier was taken on January 11, 2000.

These are the Anti-Atlas Mountains, part of the Atlas Mountain range in southern Morocco, Africa. The region contains some of the world’s largest and most diverse mineral resources, most of which are still untouched. This image was acquired by the Landsat 7 satellite on June 22, 2001. This is a false-color composite image made using shortwave infrared, infrared and red wavelengths.

In the style of Van Gogh's painting 'Starry Night,' massive congregations of greenish phytoplankton swirl in the dark water around Gotland, a Swedish island in the Baltic Sea. Phytoplankton are microscopic marine plants that form the first link in nearly all ocean food chains. Population explosions, or blooms, of phytoplankton, like the one shown here, occur when deep currents bring nutrients up to sunlit surface waters, fueling the growth and reproduction of these tiny plants. Image taken by Landsat 7 on July 13, 2005.

February 12, 1984: Mission specialist Bruce McCandless II ventures further away from the confines and safety of his ship than any previous astronaut has ever been. This space first was made possible by the Manned Manuevering Unit or MMU, a nitrogen jet-propelled backpack. After a series of test maneuvers inside and above Challenger's payload bay, McCandless went 'free-flying' to a distance of 320 feet away from the Orbiter. This stunning orbital panorama view shows McCandless out there amongst the black and blue of Earth and space.

Some of the most breathtaking views of Earth taken from space are those that capture our planet's limb. When viewed from the side, the Earth looks like a flat circle, and the atmosphere appears like a halo around it. This edge of the atmosphere is known as the limb. Viewed from space, the image of this luminous envelope of gases shielding life on our planet from the dark, cold space beyond rarely fails to fascinate us. What makes this image even more fascinating is the added silhouette of the space shuttle Endeavour. The orange layer seen is the troposphere, where all of the weather and clouds that we typically experience are created and contained. The troposphere gives way to the whitish stratosphere and then mesosphere. This image was captured by an astronaut prior to Endeavour's rendezvous and docking with the International Space Station on February 9, 2010.

Small, blocky shapes of towns, fields, and pastures surround the graceful swirls and whorls of the Mississippi River. Countless oxbow lakes and cutoffs accompany the meandering river south of Memphis, Tennessee, on the border between Arkansas and Mississippi, USA.

This interesting image shows the world’s largest glacier, Lambert Glacier in Antarctica, and icefall that flows into it. Ice flows like water, albeit much more slowly. Cracks can be seen in this icefall as it bends and twists on its slow descent 1300 feet (400 meters) to the glacier below. The image was taken by the Landsat-7 satellite on December 2, 2000 and is a false-color composite made from infrared, red and green wavelengths. The image has also been sharpened using the sensor’s panchromatic band.

In this image, it’s hard to get a sense of scale or of what we’re actually looking at. This picture, taken by the Landsat-5 satellite on 8 April, 1985, shows sand dunes (yellow streaks) that extend from Algeria into Mauritania in northwest Africa. These wind-blown sand ridges make up Erg Iguidi, one of the Sahara’s ‘sand seas’ in which individual dunes are often more than a third of a mile (500 meters) wide and tall.

This spectacular 'blue marble' image is the most detailed true-color image of the entire Earth to date. Using a collection of satellite-based observations, scientists and visualizers stitched together months of observations of the land surface, oceans, sea ice, and clouds into a seamless, true-color mosaic of every square kilometer (0.4 square miles) of our planet. Much of the information contained in this image came from NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) onboard the Terra satellite. Visualization date: August 2, 2002.

Susitna Glacier, Alaska. Like rivers of liquid water, glaciers flow downhill, with tributaries joining to form larger rivers. But where water rushes, ice crawls. As a result, glaciers gather dust and dirt, and bear long-lasting evidence of past movements. Alaska’s Susitna Glacier reveals some of its long, grinding journey in this image, taken from space on August 27, 2009. The satellite image combines infrared, red and green wavelengths to form a false-color picture. Vegetation is red and the glacier’s surface is marbled with dirt-free blue ice and dirt-coated brown ice. Infusions of relatively clean ice push in from tributaries in the north. The glacier surface appears especially complicated near the center of the image, where a tributary has pushed the ice in the main glacier slightly southward. In the lower left corner of this image, meltwater lakes can be seen on top of the ice.

This image, showing tidal flats and channels on Long Island, in the Bahamas, was taken by an Expedition 26 crew member onboard the International Space Station. The islands of the Bahamas in the Caribbean Sea are situated on large platforms made mainly from carbonate sediments ringed by fringing reefs — the islands themselves are only the parts of the platform currently exposed above sea level. The sediments are formed mostly from the skeletal remains of organisms settling to the sea floor; over geologic time, these sediments will consolidate to form carbonate sedimentary rocks such as limestone. Darker blue shows deeper water, while light blue-green shows shallow water on the tidal flat. The continually exposed parts of the island are seen in brown, a result of soil formation and vegetation growth (left).
