ESA's Mars Express Radar Gives Strong Evidence for Former Mars Ocean
ESA's Mars Express has returned strong evidence for an ocean once covering part of Mars. Using radar, it has detected sediments reminiscent of an ocean floor within the boundaries of previously identified, ancient shorelines on Mars.
3-D Image of Asteroid Vesta's Eastern Hemisphere
This 3-D image, called an anaglyph, shows the topography of Vesta's eastern hemisphere. To create this anaglyph, two differently colored images are superimposed with an offset to create depth. When viewed through red-blue glasses this anaglyph shows a 3-D view of Vesta's surface. The images used to generate the two differently colored images that make up this anaglyph were obtained during the approach phase of NASA's Dawn mission in July 2011.
Image: Impact crater on Asteroid Vesta with an unusual rim
This Dawn FC (framing camera) image shows Caparronia crater, after which Caparronia quadrangle is named. Caparronia crater has an unusually shaped, irregular rim that is sharp and fresh in some areas and more rounded and degraded in others.
Mars Express Reveals Wind-blown Deposits on Mars
New images from ESA's Mars Express show the Syrtis Major region on Mars. Once thought to be a sea of water, the region is now known to be a volcanic province dating back billions of years. Syrtis Major can be spotted from Earth even with relatively small telescopes - the near-circular dark area on the planet stretches over 1300 x 1500 km.
Image: Cratered terrain in Vesta's equatorial region
This Dawn FC (framing camera) image shows heavily cratered terrain in Vesta's equatorial region. The craters have a wide range of sizes and have many different forms, which include fresh, degraded and some that are barely visible because they are so degraded.
Grail Returns First Video from Far Side Of The Moon
A camera aboard one of NASA's twin Gravity Recovery And Interior Laboratory (GRAIL) lunar spacecraft has returned its first unique view of the far side of the moon. MoonKAM, or Moon Knowledge Acquired by Middle school students, will be used by students nationwide to select lunar images for study.
Opportunity's Eighth Anniversary View From 'Greeley Haven' (False Color)
This mosaic of images taken in mid-January 2012 shows the windswept vista northward (left) to northeastward (right) from the location where NASA's Mars Exploration Rover Opportunity is spending its fifth Martian winter, an outcrop informally named "Greeley Haven."
Opportunity's Panoramic Camera (Pancam) took the component images as part of full-circle view being assembled from Greeley Haven.
