Water Jet : Enceladus.. a Moon of Saturn , NASA Cassini Spacecraft Nov 21 2009
Dramatic plumes, both large and small, spray water ice out from many locations along the famed 'tiger stripes' near the south pole of Saturn's moon Enceladus. The tiger stripes are fissures that spray icy particles, water vapor and organic compounds.
This mosaic was created from two high-resolution images that were captured by the narrow-angle camera when NASA's Cassini spacecraft flew past Enceladus and through the jets on Nov. 21, 2009. Imaging the jets over time will allow Cassini scientists to study the consistency of their activity.

Sand Dunes on Mars, NASA/JPL-Caltech/University of Arizona: NASA's Mars Reconnaissance Orbiter Dec 28 2009
The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter captured this view on Dec. 28, 2009.
The dunes here are linear, thought to be due to shifting wind directions. In places, each dune is remarkably similar to adjacent dunes, including a reddish (or dust colored) band on northeast-facing slopes. Large angular boulders litter the floor between dunes.
The most extensive linear dune fields know in the solar system are on Saturn's large moon Titan. Titan has a very different environment and composition, so at meter-scale resolution they probably are very different from Martian dunes.
This image covers a swath of ground about 1.2 kilometers (three-fourth of a mile) wide, centered at 42.7 degrees south latitude, 38.0 degrees east longitude. It is one product from HiRISE observation ESP_016036_1370. The season on Mars is southern-hemisphere autumn. Other image products from this observation are available at http://hirise.lpl.arizona.edu/ESP_016036_1370.
The University of Arizona, Tucson, operates the HiRISE camera, which was built by Ball Aerospace & Technologies Corp., Boulder, Colo. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, manages the Mars Reconnaissance Orbiter for the NASA Science Mission Directorate, Washington. Lockheed Martin Space Systems, Denver, is the prime contractor for the project and built the spacecraft.

Men on Mission, NASA Images: STS-130 Feb 11 2010
conducted the STS-130 mission's first spacewalk on Thursday, Feb. 11, 2010.
The spacewalking pair finished all their assigned work and some get-ahead tasks. The Tranquility node and cupola were robotically maneuvered from Endeavour's payload bay, and then installed onto the port side of the Unity node. This was the first of three planned spacewalks for the STS-130 mission.

Chemical Soups Around Cool Stars , Caltech- NASA/JPL Apr 7 2009
Life on our planet is thought to have arisen out of a pond-scum-like mix of chemicals. Some of these chemicals are thought to have come from a planet-forming disk of gas and dust that swirled around our young sun. Meteorites carrying the chemicals might have crash-landed on Earth.
Astronomers don't know if these same life-generating processes are taking place around stars that are cooler than our sun, but the Spitzer observations show their disk chemistry is different. Spitzer detected a prebiotic molecule, called hydrogen cyanide, in the disks around yellow stars like our sun, but found none around cooler, less massive, reddish stars. Hydrogen cyanide is a carbon-containing, or organic compound. Five hydrogen cyanide molecules can join up to make adenine—a chemical element of the DNA molecule found in all living organisms on Earth.

Jupiter and its moon Io , Infrared color composite Image by Spacecraft Feb 28 2007
This is a montage of New Horizons images of Jupiter and its volcanic moon Io, taken during the spacecraft's Jupiter flyby in early 2007. The Jupiter image is an infrared color composite taken by the spacecraft's near-infrared imaging spectrometer, the Linear Etalon Imaging Spectral Array (LEISA) at 1:40 UT on Feb. 28, 2007. The infrared wavelengths used (red: 1.59 µm, green: 1.94 µm, blue: 1.85 µm) highlight variations in the altitude of the Jovian cloud tops, with blue denoting high-altitude clouds and hazes, and red indicating deeper clouds. The prominent bluish-white oval is the Great Red Spot. The observation was made at a solar phase angle of 75 degrees but has been projected onto a crescent to remove distortion caused by Jupiter's rotation during the scan. The Io image, taken at 00:25 UT on March 1st 2007, is an approximately true-color composite taken by the panchromatic Long-Range Reconnaissance Imager (LORRI), with color information provided by the 0.5 µm ("blue") and 0.9 µm ("methane") channels of the Multispectral Visible Imaging Camera (MVIC). The image shows a major eruption in progress on Io's night side, at the northern volcano Tvashtar. Incandescent lava glows red beneath a 330-kilometer high volcanic plume, whose uppermost portions are illuminated by sunlight. The plume appears blue due to scattering of light by small particles in the plume

S-Ring of Saturn, Cassini Spacecraft Apr 17 2009
This view from the Cassini spacecraft looks toward the unilluminated side of the rings from about 30 degrees above the ringplane. The rings have been brightened relative to the planet to enhance visibility.
Images taken using red, green and blue spectral filters were combined to create this natural color view. The images were acquired with the Cassini spacecraft wide-angle camera on Feb. 24, 2009 at a distance of approximately 866,000 kilometers (538,000 miles) from Saturn. Image scale is 38 kilometers (24 miles) per pixel.
Rainy Day at Hotei Arcus, Titan a Satellite of Saturn, Cassini Spacecraft May 21 2009
The channels seen here indicate that fluids flowed from high plateaus on the right to lowland areas on the left. In the center of the image, the wide distribution of the channels' tributaries suggests that rainfall is effectively eroding the surface. The bright terrain toward the bottom of the image is interpreted as high cliffs and broken bedrock.
These canyon systems remind us that Titan is (or has recently been) a dynamic world with a complicated geological history. Multiple channels have flowed into a wide, dark arc in the center of this mountainous region. Here, the canyons appear to have been filled by fine-grained materials that appear dark (smooth) to Cassini's synthetic aperture radar. These canyon-filling materials were later carved by a large river channel that winds from the bottom left of the image toward the left center.
The image center is at 71 degrees south latitude, 240 degrees west longitude, and its dimensions are 335 by 289 kilometers (208 by 179 miles). The radar illuminated this area from the top of the image at 18 degrees incidence angle. The areas seen here are typical of other regions observed near Titan's south pole in other flybys
Radar data show that the arc of Hotei is the boundary between rugged mountains to the south and east and a broad valley. Emerging from the mountains are several radar-bright channels that are likely now dry river beds that were carved by flowing methane due to rainfall. Within the valley, the channels end near lobate (blobby) flows some 100 to 200 meters (300 to 600 feet) thick, which some scientists think could be slushy ice lava from cryovolcanoes. These flows are portrayed here as the rough and elevated lighter tan areas in the foreground. It is possible that such phenomena could release methane from beneath the surface, helping to explain how Titan's atmosphere sustains its supply of methane.
The area depicted is located at approximately 28 degrees south latitude and 78 degrees west longitude.
Tethys- Moon of Saturn, Cassini-Huygens, Cassini Orbiter NASA JPL Jun 26 2009
The shadow of the moon Tethys is revealed on Saturn's B and C rings in this image which also includes the planet.
The planet is overexposed in this image in which the exposure time was set to capture the faint shadow on the rings. Tethys itself is not visible in this image. As Saturn approaches its August 2009 equinox, the planet's moons cast shadows onto the rings.
This view looks toward the unilluminated side of the rings from about 20 degrees above the ringplane. The image was taken in visible light with the Cassini spacecraft wide-angle camera on May 12, 2009. The view was obtained at a distance of approximately 1.2 million kilometers (746,000 miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 28 degrees. Image scale is 65 kilometers (40 miles) per pixel.
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
