NASA’s Mars Reconnaissance Orbiter discovers evidence that Gullies on Mars are being created by Dry Ice

NASA - National Aeronautics and Space AdministrationPasadena, CA – Repeated high-resolution observations made by NASA’s Mars Reconnaissance Orbiter (MRO) indicate the gullies on Mars’ surface are primarily formed by the seasonal freezing of carbon dioxide, not liquid water.

The first reports of formative gullies on Mars in 2000 generated excitement and headlines because they suggested the presence of liquid water on the Red Planet, the eroding action of which forms gullies here on Earth.

This pair of images covers one of the hundreds of sites on Mars where researchers have repeatedly used the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter to study changes in gullies on slopes. (NASA/JPL-Caltech/Univ. of Arizona)

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA Mars rover Curiosity has driven out of the ellipse, approximately 4 miles wide and 12 miles long (7 kilometers by 20 kilometers), that was mapped as safe terrain for its 2012 landing inside Gale Crater.

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter photographed the rover on June 27th at the end of a drive that put Curiosity right on the ellipse boundary.

This June 27, 2014, image from the HiRISE camera on NASA's Mars Reconnaissance Orbiter shows NASA's Curiosity Mars rover on the rover's landing-ellipse boundary, which is superimposed on the image. The 12-mile-wide ellipse was mapped as safe terrain for its 2012 landing inside Gale Crater. (NASA/JPL-Caltech/Univ. of Arizona)

NASA’s Mars Rover Opportunity explores aluminum mineral rich area on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – With its solar panels their cleanest in years, NASA’s decade-old Mars Exploration Rover Opportunity is inspecting a section of crater-rim ridgeline chosen as a priority target due to evidence of a water-related mineral.

Orbital observations of the site by another NASA spacecraft, Mars Reconnaissance Orbiter, found a spectrum with the signature of aluminum bound to oxygen and hydrogen. Researchers regard that signature as a marker for a mineral called montmorillonite, which is in a class of clay minerals called smectites.

NASA’s Curiosity Rover completes first Martian Year on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars Curiosity rover will complete a Martian year — 687 Earth days — on June 24th, having accomplished the mission’s main goal of determining whether Mars once offered environmental conditions favorable for microbial life.

One of Curiosity’s first major findings after landing on the Red Planet in August 2012 was an ancient riverbed at its landing site. Nearby, at an area known as Yellowknife Bay, the mission met its main goal of determining whether the Martian Gale Crater ever was habitable for simple life forms.

NASA's Curiosity Mars rover used the camera at the end of its arm in April and May 2014 to take dozens of component images combined into this self-portrait where the rover drilled into a sandstone target called "Windjana." (NASA/JPL-Caltech/MSSS)

NASA’s Mars Reconnaissance Orbiter discovers large new Crater on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Researchers have discovered on the Red Planet the largest fresh meteor-impact crater ever firmly documented with before-and-after images. The images were captured by NASA’s Mars Reconnaissance Orbiter.

The crater spans half the length of a football field and first appeared in March 2012. The impact that created it likely was preceded by an explosion in the Martian sky caused by intense friction between an incoming asteroid and the planet’s atmosphere.

This is the largest fresh impact crater anywhere ever clearly confirmed from before-and-after images. It is 159 feet across. (NASA/JPL-Caltech/Univ. of Arizona)

NASA - National Aeronautics and Space AdministrationPasadena, CA – Scientists using NASA’s Curiosity Mars rover are eyeing a rock layer surrounding the base of a small butte, called “Mount Remarkable,” as a target for investigating with tools on the rover’s robotic arm.

The rover works near this butte in an image taken on April 11th by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter.

NASA’s Mars Reconnaissance Orbiter discovers formation of new Gully on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A comparison of images taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter in November 2010 and May 2013 reveal the formation of a new gully channel on a crater-wall slope in the southern highlands of Mars.

Gully or ravine landforms are common on Mars, particularly in the southern highlands.

This pair of before (left) and after (right) images from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter documents formation of a new channel on a Martian slope between 2010 and 2013, likely resulting from activity of carbon-dioxide frost.

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s long-lived Mars Reconnaissance Orbiter put itself into a precautionary safe standby mode March 9th after an unscheduled swap from one main computer to another. The mission’s ground team has begun restoring the spacecraft to full operations.

“The spacecraft is healthy, in communication and fully powered,” said Mars Reconnaissance Orbiter Project Manager Dan Johnston of NASA’s Jet Propulsion Laboratory, Pasadena, CA. “We have stepped up the communication data rate, and we plan to have the spacecraft back to full operations within a few days.”

NASA’s Mars Reconnaissance, Odyssey orbiters discover Martian Slopes where Water possibly flowed

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA spacecraft orbiting Mars have returned clues for understanding seasonal features that are the strongest indication of possible liquid water that may exist today on the Red Planet.

The features are dark, finger-like markings that advance down some Martian slopes when temperatures rise. The new clues include corresponding seasonal changes in iron minerals on the same slopes and a survey of ground temperatures and other traits at active sites.

This image combines a photograph of seasonal dark flows on a Martian slope with a grid of colors based on data collected by a mineral-mapping spectrometer observing the same area. (NASA/JPL-Caltech/UA/JHU-APL)
