NASA says its Mars Reconnaissance Orbiter has returned a dramatic oblique view of a Martian crater that a rover explored for two years. The new view of Victoria Crater shows layers on steep crater walls, difficult to see from straight overhead, plus wheel tracks left by NASA's Mars Exploration Rover Opportunity between September 2005 and August 2007, the space agency said. The orbiter's High Resolution Imaging Science Experiment camera shot it at an angle comparable to looking at landscape...

This image of Victoria Crater in the Meridiani Planum region of Mars was taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter at more of a sideways angle than earlier orbital images of this crater. The camera pointing was 22 degrees east of straight down, yielding a view comparable to looking at the landscape out an airplane window. East is at the top. The most interesting exposures of geological strata are in the steep walls of the...

The U.S. space agency says its Mars Reconnaissance Orbiter has resumed full operations, conducting intensive science observations of Mars. The operations resumed Monday, four days after the spacecraft unexpectedly switched to its backup computer. Mission engineers at NASA's Jet Propulsion Laboratory in Pasadena, Calif., and at Lockheed Martin Space Systems in Denver said they were able to resume operations of the spacecraft's science instruments Monday at 5:32 p.m. EDT. Now the engineers say...

NASA's long-lived Mars Odyssey spacecraft has completed an eight-month adjustment of its orbit, positioning itself to look down at the day side of the planet in mid-afternoon instead of late afternoon. This change gains sensitivity for infrared mapping of Martian minerals by the orbiter's Thermal Emission Imaging System camera. Orbit design for Odyssey's first seven years of observing Mars used a compromise between what worked best for the infrared mapping and for another onboard instrument....

NASA's Mars Reconnaissance Orbiter is in safe mode and in communications with Earth after an unexpected rebooting of its computer Wednesday evening, June 3. The spontaneous reboot resembles a Feb. 23 event on the spacecraft. Engineers concluded the most likely cause for that event was a cosmic ray or solar particle hitting electronics and causing an erroneous voltage reading. Jim Erickson, Mars Reconnaissance Orbiter project manager at NASA's Jet Propulsion Laboratory, Pasadena, Calif., said,...

The team operating NASA's Mars Exploration Rover Spirit is examining data received from Spirit in recent days to diagnose why the rover apparently rebooted its computer at least twice over the April 11-12 weekend. "While we don't have an explanation yet, we do know that Spirit's batteries are charged, the solar arrays are producing energy and temperatures are well within allowable ranges. We have time to respond carefully and investigate this thoroughly," said John Callas of NASA's Jet...

Exciting new images of the moon and Mars from NASA's orbiting observatories will enable users of all ages to explore the universe through the Microsoft WorldWide Telescope. WASHINGTON and REDMOND, Wash., March 24 /PRNewswire-FirstCall/ -- NASA and Microsoft Corp. today announced plans to make planetary images and data available via the Internet under a Space Act Agreement. Through this project, NASA and Microsoft will jointly develop the technology and infrastructure necessary to make the...

NASA and Microsoft Corp. announced Tuesday plans to make planetary images and data available via the Internet under a Space Act Agreement. Through this project, NASA and Microsoft jointly will develop the technology and infrastructure necessary to make the most interesting NASA content -- including high-resolution scientific images and data from Mars and the moon -- explorable on WorldWide Telescope, Microsoft's online virtual telescope for exploring the universe. "Making NASA's scientific...

The U.S. space agency says its Mars Reconnaissance Orbiter is working once again after an unexpected computer reboot last week. National Aeronautics and Space Administration engineers at the Jet Propulsion Laboratory in Pasadena, Calif., sent commands Monday to power up the spacecraft's science instruments. The scientists said Tuesday monitoring confirmed all instruments were working properly. The Mars Reconnaissance Orbiter unexpectedly rebooted its computer Feb. 23 and put itself into a...

HiRISE finds fractured lavas before now seen only on Earth. Unique fractures in lavas on ancient Mars suggest water occasionally flooded portions of the planet's surface. The fractures, known as "columnar joints," are the first that have been observed on a planet other than Earth. "Columnar joints form as cooling lava contracts," said Moses Milazzo, a geophysicist with the U. S. Geological Survey Astrogeology Team in Flagstaff. The characteristics of the column-like fractures can help...
