The six aluminum wheels that support the unmanned explorer are starting to show significant signs of wear, with two new small breaks in the metal treads of the left-side middle wheel. However, NASA expects the wheels will go the distance to allow the rover to complete its planned mission.

Another hopeful sign that Mars was once habitable has been discovered by Curiosity, with the detection of nitrogen in soil samples. While NASA doesn't think that the compounds are biological in origin, they are still significant to Mars having been more favorable to life in the ancient past.

The hunt for present or past life on Mars got a boost as NASA's Curiosity rover records spikes in atmospheric methane ten times greater than previously measured by the unmanned probe.

NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft has used a special radio apparatus to relay 550 megabits of data from the Curiosity rover to NASA’s Deep Space Network back on Earth.

After over two years on Mars, NASA’s Curiosity rover has reached its primary objective, Mount Sharp. Located in the center of Gale Crater, this will be the centerpiece of a new program of study to locate areas where could or once could have supported microbial life.

Break out the party hats because NASA’s Curiosity rover is celebrating its second anniversary on Mars. Two years ago today, the unmanned spacecraft touched down at Bradbury Landing in Gale Crater on the start of a multi-year mission to study the Red Planet.

The chances of life having once existed on Mars got a boost this week and there was good news for astronauts on any future expeditions to the red Planet. On Monday, NASA announced six papers presented to the autumn meeting of the American Geophysical Union in San Francisco.

Water, like gold, is where you find it and NASA’s Curiosity Mars rover has discovered water in the Martian soil in greater quantities than expected.

Today NASA paid tribute to its Curiosity rover, which has completed its first year exploring the planet Mars. Gizmag looks at 10 milestones of the mission so far.

On Wednesday, NASA unveiled a rather large postcard sent back from Mars in the form a panoramic image over a gigapixel in size.

NASA’s Curiosity Mars rover has completed its first soil analysis of the Red Planet, revealing that Martian soil is a weathered volcanic type similar to soils found in the Hawaiian Islands.

The object that NASA’s Curiosity Mars rover found on Sunday is probably a piece of plastic that fell off the unmanned exploration vehicle
