NASA's new Mars picture
The US space agency NASA has recently pieced together a panoramic view from the camera on NASA's Mars Exploration Rover Opportunity, calling it the "next best thing to being" on the Red Planet.
Here's The Most Stunning Photo of Mars The World Has Ever Seen
A TextureCam analysis of a Mars image is able to distinguish rocks from soil.
Future Planetary Rovers May Make Their Own Decisions In this undated image provided by NASA, Mars Rover Opportunity catches its own late-afternoon shadow in a view eastward across Endeavour Crater on Mars. The rover used a panoramic camera between about 4:30 and 5:00 p.m. local Mars time to record images taken through different filters and combined into this mosaic view. Most of the component images were recorded during the 2,888th Martian day, or sol, of Opportunity's work on Mars, which corresponds to March 9, 2012 on Earth. The view is presented in false color to make some differences between materials easier to see, such as the dark sandy ripples and dunes on the crater's distant floor. Opportunity has been studying the western rim of Endeavour Crater since arriving there in August 2011.

A close-up of the sunset on Sol 24 as seen by the Imager for Mars Pathfinder was released by the Jet Propulsion Labratory August 27. The red sky in the background and the blue around the Sun are approximately as they would appear to the human eye but the color of the Sun itself is not correct -- the Sun was overexposed in each of the 3 color images that were used to make the picture. The true color of the Sun itself may be near white or slightly bluish.
A portion of the west rim of Endeavour crater sweeps southward in this color view from NASA's Mars Exploration Rover Opportunity released by NASA August 10, 2011. This crater has a diameter of about 14 miles (22 km). This view combines exposures taken by Opportunity's panoramic camera (Pancam) of the rover's work on Mars August 6, 2011. Opportunity arrived at the rim during its next drive on August 9, 2011. Endeavour crater has been the rover team's destination for Opportunity since the rover finished exploring Victoria crater in August 2008. Endeavour offers access to older geological deposits than any Opportunity has seen before. The lighter-toned rocks closer to the rover in this view are similar to the rocks Opportunity has driven over for most of the mission. However, the darker-toned and rougher rocks just beyond that might be a different type for Opportunity to investigate. The ground in the foreground is covered with iron-rich spherules, nicknamed "blueberries," which Opportunity has observed frequently since the first days after landing. They are about 0.2 inch (5 millimeters) or more in diameter. REUTERS/NASA/JPL-Caltech/Cornell/ASU/Handout (UNITED STATES - Tags: SCI TECH) FOR EDITORIAL USE ONLY.
