Mars TOP STORY
At Mars' North Pole is a dome of icy layers ranging up to 2 kilometers thick, roughly analogous to the Earth's ice caps in Greenland or Antarctica.

Curiosity Rover Camera Captures Laser- Induced Spark
NASA's Curiosity Mars rover used the Mars Hand Lens Imager (MAHLI) camera on its arm to catch the first images of sparks produced by the rover's laser being shot at a rock on Mars.
This rock encountered by NASA's Curiosity Mars rover is an iron meteorite called "Lebanon," similar in shape and luster to iron meteorites found on Mars by the previous generation of rovers, Spirit and Opportunity. Lebanon is about 2 yards or 2 meters wide (left to right, from this angle). The smaller piece in the foreground is called "Lebanon B."
Beginning in the late 1960s with the Mariner 4, 6, and 7 fly-bys, spacecraft began imaging Mars from closer perspectives.
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.
Airbus Defence and Space, the world's second largest space company, has just completed the production of the two heat shields for the first European ExoMars mission in 2016.
In chambers that mimic Mars' conditions, University of Michigan researchers have shown how small amounts of liquid water could form on the planet despite its below-freezing temperatures.
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.
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."
On June 24, 2014, NASA's Curiosity (Mars Science Laboratory) rover completes her first Martian year (687 Earth days). Hear team members describe how the mission accomplished its main goal to find a past habitable environment on the Red Planet and the ongoing science studies.
In late May, NASA's Swift satellite imaged comet Siding Spring, which will brush astonishingly close to Mars later this year. These optical and ultraviolet observations are the first to reveal how rapidly the comet is producing water and allow astronomers to better estimate its size.
Sandy landforms formed by the wind, or aeolian bedforms, are classified by the wavelength--or length--between crests.
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 (MRO).
The rim surrounding Endeavour Crater on Mars recedes southward, then sweeps around to the east in a vista obtained by NASA's Mars Exploration Rover Opportunity.
Rabe Crater is a 108 km-wide impact crater with an intricately shaped dune field. The dune material likely comprises locally eroded sediments that have been shaped by prevailing winds.
This past November, NASA launched the Mars Atmosphere and Volatile Evolution (MAVEN) mission in the hope of understanding how and why the planet has been losing its atmosphere over billions of years.
Portions of rock powder collected by the hammering drill on NASA's Curiosity Mars rover from a slab of Martian sandstone will be delivered to the rover's internal instruments.
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 about every six weeks.
