This Voyager 2 image, taken Aug. 18 from a distance of 6.8 million kilometers (4.2 million miles), shows the region extending from 20 north latitude to Saturn?s polar region. Several small-scale spots evident at around 37 north move in an easterly jet at a speed approaching 15 meters-per-second (33 mph). Toward the boundary with the white cloud band are several cloud strands that mark part of the westerly flow of the atmosphere. This flow reaches a maximum in the ?ribbonlike? structure, with...

These photos of the four Galilean satellites of Jupiter were taken by Voyager 1 during its approach to the planet in early March 1979. Io (top left), Europa (top right), Ganymede (bottom left) and Callisto (bottom right) are shown in their correct relative sizes: Ganymede and Callisto are both larger than the planet Mercury; Io and Europa are about the same size as the Moon. Image processing also preserves the relative contrasts of the satellites. Thus it is apparent that Europa has the least...

On January 26, 2001, the Kachchh region in western India suffered the most deadly earthquake in India's history. Shortly thereafter, geologists traversed the region looking for ground surface disruptions, such as fault breaks, that could provide clues to the tectonic processes here. Shuttle Radar Topography Mission (SRTM) scientists provided stereoscopic images to the geologists, similar to this 3-D view of the terrain northwest of the city of Bhuj.

During its flight, the Galileo spacecraft returned images of the Moon. The Galileo spacecraft took these images on December 7, 1992 on its way to explore the Jupiter system in 1995-97. The distinct bright ray crater at the bottom of the image is the Tycho impact basin. The dark areas are lava rock filled impact basins: Oceanus Procellarum (on the left), Mare Imbrium (center left), Mare Serenitatis and Mare Tranquillitatis (center), and Mare Crisium (near the right edge).

The north polar residual ice cap of the Planum Boreum region, which is cut by spiral-patterned troughs, is located at top. The upper part is marked by large depression, Isidis basin, which contains light-colored plains. The upper part also includes the light-colored smooth plains of Elysium Planitia and dark plains of Vastitas Borealis. Together,...

This pattern of eroded, and perhaps deformed layers was once exposed to the martian surface, then buried, and more recently exposed again. The story behind these layers is not really understood; some members of the MOC team have -- for nearly 9 years now -- taken...

On May 18, 1980, Mount St. Helens catastrophically erupted, causing the worst volcanic disaster in the recorded history of the United States. An earthquake shook loose the northern flank of the volcano, and about 2.8 cubic kilometers (0.67 cubic miles) of rock slid downslope in the world's largest recorded landslide. The avalanche released pressure on the volcano and unleashed a huge explosion, which was directed generally northward. The mountain ultimately lost 227 meters (1314 feet) of its...

This HiRISE image shows an impact crater in Utopia Planitia, in the northern hemisphere of Mars, that is filled with layered material. The layered character of these deposits is consistent with episodic deposition. Each distinct layer represents a period of sediment deposition. The layers are parallel to each other, indicating that deposition occurred by material settling onto the surface, rather than being blown across the surface in sand dunes. The hummocky texture of these deposits suggests...

NASA's Viking 1 Orbiter spacecraft photographed this region in the northern latitudes of Mars on July 25, 1976 while searching for a landing site for the Viking 2 Lander. The speckled appearance of the image is due to missing data, called bit errors, caused by problems in transmission of the photographic data from Mars to Earth. Bit errors comprise part of one of the 'eyes' and 'nostrils' on the eroded rock that resembles a human face near the center of the image. Shadows in the rock formation...

This montage of images of the Saturnian system was prepared from an assemblage of images taken by the Voyager 1 spacecraft during its Saturn encounter in November 1980. This artist's view shows Dione in the forefront, Saturn rising behind, Tethys and Mimas fading in the distance to the right, Enceladus and Rhea off Saturn's rings to the left, and Titan in its distant orbit at the top. The Voyager Project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, California.

A shallow 12-inch-long trench was dug by Viking 2 s surface sampler scoop yesterday (September 12) on Mars. The trench is difficult to see in this photo because it is in the shadow of a rock (out of view to the right). The sampler scoop stopped operating sometime after soil was excavated from the trench and delivered to Viking 2 s biology instrument.

The unlit side of the rings glows with scattered sunlight as two moons circle giant Saturn. The light reaching Cassini in this view has traveled many paths before being captured. At left, Mimas (397 kilometers, or 247 miles across) presents its dark side. Enceladus (505 kilometers, or 314 miles across), on the far side of the rings, is lit by "Saturnshine," or reflected sunlight coming from the planet. Saturn, in turn, is faintly lit in the south by light reflecting off the rings....

Data from Odyssey's Martian radiation environment experiment show that the radiation dose equivalent at Mars is two to three times greater than that aboard the International Space Station. The differences are primarily due to the magnetic field surrounding the Earth, which provides considerable shielding to astronauts in orbit.
