After the Mars Reconnaissance Orbiter began beaming back close-up images of the Red Planet, researchers spotted peculiar features along the slopes of dunes: long, sharply defined grooves (pictured) that seem to appear and disappear seasonally. Show More Summary
The Mars Reconnaissance Orbiter just keeps delivering remarkable scenes from the Red Planet.
Interannual and seasonal changes in the north polar ice deposits of Mars: Observations from MY 29-31 using MARCIAuthors:Calvin et alAbstract:The MARCI camera on the Mars Reconnaissance Orbiter provides daily synoptic coverage that allows...Show More Summary
The technology used to map to Mars is advancing at a thrilling rate and uncovering all kinds of curiosities. The latest head-scratching image comes from the Mars Reconnaissance Orbiter's High Resolution Imaging Science Experiment (HiRISE). It reveals a series of mysterious sandy ridges. No one knows exactly how they got there. Read more...
NASA plans to extend seven of its ongoing planetary missions, a review panel announced yesterday. Two of the missions, the Lunar Reconnaissance Orbiter and the Mars rover Opportunity, were at risk of being shut down, b ut it was Mars rover Curiosity that drew the least-favorable reviews, and the harshest criticisms. Read more...
NASA has a case of Mars rock and roll... literally. The agency's Mars Reconnaissance Orbiter currently orbiting the Red Planet has spotted the trail left behind after a tall boulder tumbled down a Martian slope. The Mars rock's misshapen prints are clearly visible in the spacecraft's view from orbit. Show More Summary
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...Show More Summary
How scientists are working with CRISM, an aging but still exceptional spectrometer on Mars Reconnaissance Orbiter, to find the rocks where Opportunity's work will tell the story of ancient water on Mars.
If life existed on Mars in the recent past, the best spot for it could have been on a giant volcano once encrusted with a glacier, according to a team of Brown University scientists using data from NASA’s Mars Reconnaissance Orbiter...
YouTube link A series of before-and-after images captured by NASA's Mars Reconnaissance Orbiter reveal the largest fresh-impact crater ever documented in our solar system. Researchers think the impact that made the crater happened in the spring of 2012, when it first appeared in NASA images taken of Mars. Show More Summary
Mars Express and Mars Reconnaissance Orbiter are keeping their eyes in the sky on Curiosity. There's a nice newly public color image of all of Gale Crater from HiRISE, and two new HiRISE images within the Curiosity landing site.
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. Show More Summary
Image Credit: NASA/JPL-Caltech/Univ. of Arizona Alfred McEwen The resemblance is uncanny, but no, these aren’t Starfleet logos emblazoned on planet Vulcan. Perhaps fittingly, though, this nasa Mars Reconnaissance Orbiter image shows a section of an active dune field on Mars. Show More Summary
Nili Patera is one of the most active dune fields on Mars. As such, it is continuously monitored with the HiRISE (High Resolution Imaging Science Experiment) camera, a science instrument aboard NASA's Mars Reconnaissance Orbiter, with a new image acquired...
The Curiosity Rover keeps on trekking. An image captured by the NASA's Mars Reconnaissance Orbiter offers a spectacular view of Curiosity's journey of discovery as it winds its way across the Red Planet. Read more...
A Mars Reconnaissance Orbiter HiRISE image taken on February 10 shows Curiosity having just made deep, dark tracks across the Dingo Gap dune.
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. read more
NASA's Mars Reconnaissance Orbiter (MRO) put itself into a precautionary "safe mode" March 7, but the venerable spacecraft is now on the mend, agency officials say. MRO switched over to safe mode after unexpectedly swapping from one main computer to another, NASA officials said March 11. Show More Summary
These shapes certainly look familiar to Star Trek fans, and even the Shat. This is a picture of sand dunes on the surface of Mars, in an image taken by the HiRISE camera on board the Mars Reconnaissance Orbiter. Technically, they’re called barchan dunes. Show More Summary
On Nov. 4, 2013, NASA's Mars Reconnaissance Orbiter snapped a stunning image of the planet's sand dunes
