NASA's Mars Science Laboratory rover Curiosity appears as a bluish dot near the lower right corner of this enhanced-color view from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.
Researchers at Brown University have shown that some Martian valleys appear to have been caused by runoff from orographic precipitation — moisture carried part of the way up a mountain and deposited on the slopes.
The latest drive by NASA's Curiosity Mars rover brought the total distance that the rover has driven on Mars to more than 1 kilometer. One kilometer is about 0.62 mile.
Researchers, in a step toward analyzing Mars for signs of life, find that gene-sequencing chip can survive space radiation.
NASA's Mars Curiosity rover is on the road again, continuing its trek across the Red Planet. With drives on July 4 and July 7, the rover departed its last scientists target in the "Glenelg" area and has begun its many-month overland journey to its next destination--Mount Sharp.
NASA's Mars rover Curiosity has been trekking across the Red Planet, collecting crucial data as it drills into rocks and gathers samples. Now, the rover has caught stunning images of one of Mars' two tiny moons climbing high into the sky during a fantastic moonrise.
Mars has surprised NASA scientists again and again. Now, scientists have found that the Red Planet may have had an oxygen-rich atmosphere about 4,000 million years ago--well before the rise of atmospheric oxygen on Earth about 2,500 million years ago.
Dramatic flood events carved this impressive channel system on Mars covering 1.55 million square kilometres, shown here in a stunning new mosaic from ESA’s Mars Express.
NASA Mars rover Opportunity isn't just on the move, it's also discovered a clay-rich rock that hints to the fact that water existed on the Red Planet in the past.
New global maps of Mars released on the 10th anniversary of the launch of ESA’s Mars Express trace the history of water and volcanic activity on the Red Planet, and identify sites of special interest for the next generation of Mars explorers.
NASA's Mars Curiosity rover has confirmed the hazards of space radiation. Sending astronauts to the Red Planet without a properly protected spacecraft could drastically increase their risk of cancer.
There may be more evidence for life on Mars. Researchers have discovered that a chemical reaction between iron-containing minerals and water may produce enough hydrogen "food" to sustain microbial communities living in pores and cracks within the enormous volume of rock below the ocean floor and par...
