Terrain that NASA's Curiosity Mars rover is now crossing is as smooth as team members had anticipated based on earlier images from orbit. On Tuesday, Feb. 18, the rover covered 329 feet (100.3 meters), the mission's first long trek that used reverse driving and its farthest one-day advance of any kind in more than three months.
Researchers have determined the now-infamous Martian rock resembling a jelly doughnut, dubbed Pinnacle Island, is a piece of a larger rock broken and moved by the wheel of NASA's Mars Exploration Rover Opportunity in early January.
NASA's Mars Odyssey spacecraft has tweaked its orbit to help scientists make the first systematic observations of how morning fogs, clouds and surface frost develop in different seasons on the Red Planet.
NASA's Curiosity Mars rover reached the edge of a dune on Jan. 30 and photographed the valley on the other side, to aid assessment of whether to cross the dune.
The team operating NASA's Mars rover Curiosity is considering a path across a small sand dune to reach a favorable route to science destinations. A favorable route would skirt some terrain with sharp rocks considered more likely to poke holes in the rover's aluminum wheels.
Some of the oldest minerals ever analyzed by NASA’s Mars Opportunity Rover show that around four billion years ago Mars had liquid water so fresh it could have supported life. The findings were announced in a special 'Exploring Mars Habitability' edition of the journal Science released last week to coincide with the 10th anniversary of the Mars Opportunity Rover and its twin, Spirit, landing on the red planet.
Ten years ago, on 14 January 2004, Mars Express took its very first images of Mars in color and in 3D.
Eighth graders didn't have Facebook or Twitter to share news back then, in January 2004. Bekah Sosland, 14 at the time, learned about a NASA rover landing on Mars when the bouncing-ball video on the next morning's Channel One news in her Fredericksburg, Texas, classroom caught her eye.
NASA's Mars Reconnaissance Orbiter has revealed to scientists slender dark markings -- possibly due to salty water – that advance seasonally down slopes surprisingly close to the Martian equator.
Scientists have found evidence that there was once an ancient lake on Mars that may have been able to support life, in research published today in the journal Science.
NASA's Curiosity Mars rover has passed the milestone of 100,000 shots fired by its laser. It uses the laser as one way to check which chemical elements are in rocks and soils.
Science observations by NASA's Mars rover Curiosity have been suspended for a few days while engineers run tests to check possible causes of a voltage change detected on Nov. 17.
For nearly as long as astronomers have been able to observe asteroids, a question has gone unanswered: Why do the surfaces of most asteroids appear redder than meteorites — the remnants of asteroids that have crashed to Earth?
Researchers now have stronger evidence of granite on Mars and a new theory for how the granite – an igneous rock common on Earth -- could have formed there, according to a new study. The findings suggest a much more geologically complex Mars than previously believed.
NASA's Mars rover Curiosity experienced an unexpected software reboot (also known as a warm reset) yesterday (11/7/13) during a communications pass as it was sending engineering and science data to the Mars Reconnaissance Orbiter, for later downlinking to Earth.
Earlier this week, NASA's Mars Exploration Rover began climbing "Solander Point," the northern tip of the tallest hill it has encountered in the mission's nearly 10 Earth years on Mars.
Scientists from NASA and the Planetary Science Institute in Tucson, Ariz., have identified what could be a supervolcano on Mars—the first discovery of its kind.
The volcano in question, a vast circular basin on the face of the Red Planet, previously had been classified as an impact crater.
Lessons from underground nuclear tests and explosive volcanoes may hold the answer to how a category of unusual impact craters formed on Mars. The craters feature a thin-layered outer deposit that extends well beyond the typical range of ejecta, said Nadine Barlow, professor of physics and astronomy at Northern Arizona University.
NASA has released its announcement of an open competition for the planetary community to submit proposals for the science and exploration technology instruments that would be carried aboard the agency's next Mars rover, scheduled for launch in July/August of 2020.
NASA's Curiosity rover is revealing a great deal about Mars, from long-ago processes in its interior to the current interaction between the Martian surface and atmosphere.
