This mosaic of four side-by-side microscope images (one a color composite) was acquired by the Optical Microscope, a part of the Microscopy, Electrochemistry, and Conductivity Analyzer (MECA) instrument suite on NASA's Phoenix Mars Lander.
Taken on the ninth Martian day of the mission, or Sol 9 (June 3, 2008), the image shows a 3 millimeter (0.12 inch) diameter silicone target after it has been exposed to dust kicked up by the landing. It is the highest resolution image of dust and sand ever acquired on Mars. The silicone substrate provides a sticky surface for holding the particles to be examined by the microscope.
The Phoenix Mission is led by the University of Arizona, Tucson, on behalf of NASA. Project management of the mission is by NASA's Jet Propulsion Laboratory, Pasadena, Calif. Spacecraft development is by Lockheed Martin Space Systems, Denver.

Promethei Planum, an area seasonally covered with a more than 3500 m thick layer of ice in the martian south polar region, was the subject of the High Resolution Stereo Camera’s focus on 22 September 2005 as Mars Express was in orbit above the Red Planet.
Satellites shed light on global warming
As climate change continues to make headlines across the world, participants at the 2007 Envisat Symposium this week are hearing how Earth observation satellites allow scientists to better understand the parameters involved in global warming and how this is impacting the planet.
Opportunity Recovers from Brief Operational Anomaly
While Opportunity was collecting images with the panoramic camera on the rover's 902nd Martian day, or sol (Aug. 7, 2006), a spacecraft anomaly at 11:19 a.m. local solar time caused the rover's fault protection software to interrupt operations, place the rover in a safe state, and reboot the flight software.
Largest ever galaxy portrait - stunning HD image of Pinwheel Galaxy
Giant galaxies weren't assembled in a day. Neither was this Hubble Space Telescope image of the face-on spiral galaxy Messier 101 (the Pinwheel Galaxy). It is the largest and most detailed photo of a spiral galaxy beyond the Milky Way that has ever been publicly released. The galaxy's portrait is actually composed from 51 individual Hubble exposures, in addition to elements from images from ground-based photos. The final composite image measures a whopping 16,000 by 12,000 pixels.
Microscopic View on Mars
NASA's Mars Exploration Rover Spirit used its microscopic imager to capture this spectacular, jagged mini-landscape on a rock called "GongGong." Measuring only 3 centimeters (1.2 inches) across, this surface records two of the most important and violent forces in the history of Mars -- volcanoes and wind.
Tempel 1 is weak X-ray source, XMM-Newton confirms
ESA's XMM-Newton observations of Comet 9P/Tempel 1 revealed that the object is a weak X-ray source. These data were acquired on 4 July 2005 by one of the EPIC X-ray cameras on board the spacecraft during the post-impact observation phase.
NASA and the Universe Send a Celestial Valentine
The candles are lit, the champagne is on ice. All you need now are flowers and a ring. This Valentine's Day, NASA's Spitzer and Cassini spacecraft provide you with both, in two engaging new images. NASA's Cassini-Huygens mission and Spitzer Space Telescope have captured images of Saturn's rings and the Ring Nebula, respectively, to bring home spectacular views of two of the most looked-at objects in the sky. The Cassini image shows a detailed color mosaic of Saturn's shimmering rings. Spitzer imaged the outer shell of the Ring Nebula, which looks surprisingly similar to the delicate petals of a camellia blossom.
NASA supercomputer shows how dust rings point to exo-Earths
(PhysOrg.com) -- Supercomputer simulations of dusty disks around sunlike stars show that planets nearly as small as Mars can create patterns that future telescopes may be able to detect. The research points to a new avenue in the search for habitable planets.
