NASA's Mars rover Curiosity has begun the steep ascent of an iron-oxide-bearing ridge that's grabbed scientists' attention since before the car-sized rover's 2012 landing.
Wispy, early-season clouds resembling Earth's ice-crystal cirrus clouds move across the Martian sky in some new image sequences from NASA's Curiosity Mars rover.
This month, movements of the planets will put Mars almost directly behind the sun, from Earth's perspective, causing curtailed communications between Earth and Mars.
The car-size NASA rover on a Martian mountain, Curiosity, has begun its long-anticipated study of an iron-bearing ridge forming a distinctive layer on the mountain's slope.
A.I. software on NASA's Curiosity Mars rover has helped it zap dozens of laser targets on the Red Planet this past year, becoming a frequent science tool when the ground team was out of contact with the spacecraft. This same software has proven useful enough that it's already scheduled for NASA's upcoming mission, Mars 2020.
Using the most powerful telescope ever sent to Mars, NASA's Mars Reconnaissance Orbiter caught a view of the Curiosity rover this month amid rocky mountainside terrain.
NASA has found diverse minerals in rocks examined by the Curiosity rover on lower Mount Sharp, Mars. These suggest that wet environmental conditions there changed over time.
A long-lasting lake on ancient Mars provided stable environmental conditions that differed significantly from one part of the lake to another, according to a comprehensive look at findings from the first three-and-a-half years of NASA's Curiosity rover mission.
Pale "halos" around fractures in bedrock analyzed by NASA's Curiosity Mars rover contain copious silica, indicating that ancient Mars had liquid water for a long time.
As it drives uphill from a band of rippled sand dunes, NASA's Curiosity Mars rover is toting a fistful of dark sand for onboard analysis that will complete the rover's investigation of those dunes.
Peter Theisinger, who led projects that developed multiple NASA rovers that successfully landed on Mars, will receive a National Air and Space Museum Lifetime Achievement Trophy.
A routine check of the aluminum wheels on NASA's Curiosity Mars rover has found two small breaks on the rover's left middle wheel-the latest sign of wear and tear as the rover continues its journey, now approaching the 10-mile (16 kilometer) mark.
On Mars, wind rules. Wind has been shaping the Red Planet's landscapes for billions of years and continues to do so today. Studies using both a NASA orbiter and a rover reveal its effects on scales grand to tiny on the strangely structured landscapes within Gale Crater.
Evidence shows ancient Mars sometimes had water on its surface. Yet climate modelers struggle to produce scenarios where its surface is warm enough to keep water unfrozen.
Scientists used NASA's Curiosity Mars rover in recent weeks to examine slabs of rock cross-hatched with shallow ridges that likely originated as cracks in drying mud.
