It wasn't any more pleasant on Mars a billion years ago.

NASA has unveiled images of the first-ever craters on Mars discovered by AI. The system spotted the craters by scanning photos by NASA’s Mars Reconnaissance Orbiter, which was launched in 2005 to study the history of water on the red planet. The cluster it detected was created by several pieces of a single meteor, which had shattered into pieces while flying through the Martian sky at some point between March 2010 and May 2012. The fragments landed in a region called Noctis Fossae, a long, narrow, shallow depression on Mars. They left behind a series of craters spanning about 100 feet (30 meters) of the planet’s surface.… This story continues at The Next WebOr just read more coverage about: NASA

Sometime between March 2010 and May 2012, a meteor streaked across the Martian sky, where it broke into pieces and crashed into the Red Planet’s surface. The resulting craters were relatively small at 13-feet in diameter. The smaller features are on the planet’s surface, the more difficult it is to discover the from the Mars orbiters. For the first time, … Continue reading

NASA has spent years observing and exploring Mars, but the Mars Reconnaissance Orbiter took a picture of a ridged portion of the Martian surface last month that is "puzzling" to researchers.

Scientists have come up with at least one possible explanation, but answers are elusive.

We’ve all seen videos and pictures of avalanches, at least ones that happen on Earth. Though they happen in many places, they’re all the same: huge amounts of some material breaks free from a tall structure, causing a cascading effect in which massive amounts of the material roll downward. This is often associated with huge amounts of snow, but can … Continue reading
A dust devil, an avalanche, a moon and a crater all made the cut of top Mars Reconnaissance Orbiter images.
NASA has spent years investigating Mars up close and personal with its various rovers and spacecraft, the latter of which includes the Mars Reconnaissance Orbiter (MRO). This spacecraft orbits Mars, using onboard cameras to snap images of the Red Planet below. This has resulted in a huge number of images, some of which are so strikingly beautiful that they look … Continue reading
NASA's newest rover is carrying a helicopter in its belly all the way to Mars after its successful launch.
Satellite observations of Jezero crater on Mars, the chosen landing site for NASA’s next rover mission, have revealed evidence of minerals that are exceptionally good at preserving traces of ancient life, making this an even better place to send the rover than initially thought.If primitive life existed on Mars billions of years ago – and that’s still a big if – there’s an excellent chance the fossilised remains of this life could be found in Jezero crater, according to two recent studies.This is great news, given that NASA’s yet-to-be-named 2020 rover will be launched to this exact spot next year.That Jezero crater is an excellent target for the rover is hardly a surprise, as it was carefully chosen by NASA owing to its potentially life-friendly properties, or at least its former potentially life-friendly properties.Billions of years ago, this 49-kilometre-wide (30-mile) crater was brimming with water from a large nearby watershed and its associated rivers.Accordingly, NASA wants the 2020 rover to explore clay minerals in the crater and examine its sediment layers, but the latest research points to some other tantalising targets.
Boffins pour, er, cold liquid on theories of melting waterThe mountains and ridges on Mars – which some believe are carved from melting ice – can also be formed by landslides, according to a paper published in Nature Communications on Thursday.Scientists, led by the eggheads at University College London in England, have effectively cast doubt over previous studies that support the idea that melting ice may be sculpting the Red Planet.The long winding slopes down its peaks show that material has shifted over time.Similar patterns have been observed on Earth, caused by our world's melting glaciers, leading some academics to believe that there may be ice lurking close to the Martian surface, which melts and flows downhill, leaving channels in its wake.This latest study reveals that belief may not be the case.
NASA’s Mars Reconnaissance Orbiter (MRO) is currently in orbit around the red planet and is snapping photos of its surface using an instrument called the High-Resolution Imaging Science Experiment (HiRISE).Recently, HiRISE imaged not just one but both of NASA’s missions which are on the planet right now.First up, HiRISE took the image above showing the most detailed aerial view yet of the InSight lander.The greenish speck in the middle of the image is the landing site in the Elysium Planitia region, and you can see the two circular panels that the lander uses to collect solar power.Just below the lander, you can see the dome of the heat shield covering the seismometer which is listening out for marsquakes.About 373 miles (600 kilometers) away from InSight, the Curiosity rover is exploring, as you can see in the images above.
New images taken by the Mars Reconnaissance Orbiter are providing fresh views of NASA’s Insight lander and Curiosity rover on the Martian surface.The Opportunity rover died last year after being smothered by dust, which means NASA has just two robotic probes currently investigating the Martian surface: the six-wheeled Curiosity rover and the immobile InSight lander.Flying high above in space, however, is NASA’s Mars Reconnaissance Orbiter (MRO), which regularly scans the Martian surface in search of cool new things, like dried-up river channels, fresh impact craters, and the occasional, ahem, elephant.Sometimes the orbiter’s HiRISE camera looks down upon the machines below.This happened recently, according to a NASA press release, so we’ve got some nice new photos of Curiosity and InSight.MRO took the picture above on September 23, 2019 from a height of 272 kilometres (169 miles).
