Scientists using NASA's Curiosity Mars rover are eyeing a rock layer surrounding the base of a small butte, called "Mount Remarkable," as a target for investigating with tools on the rover's robotic arm.
If desert mirages occur on Mars, "Lake Gusev" belongs among them. This come-and-go body of ancient water has come and gone more than once, at least in the eyes of Mars scientists.
Last week, NASA's Curiosity Mars rover drove the last 98 feet feet (30 meters) needed to arrive at a site planned since early 2013 as a destination for studying rock clues about ancient environments that may have been favorable for life.
A state-of-the-art ‘Mars yard’ is now ready to put the ExoMars rover through its paces before the vehicle is launched to the Red Planet in 2018.
How do you grow a supermassive black hole that is a million to a billion times the mass of our sun? Astronomers do not know the answer, but a new study using data from NASA's Wide-field Infrared Survey Explorer, or WISE, has turned up what might be the cosmic seeds from which a black hole will sprout. The results are helping scientists piece together the evolution of supermassive black holes -- powerful objects that dominate the hearts of all galaxies.
A research team in Spain has the enviable job of testing out new electromechanical gear for potential use in future missions to the "Red Planet." They do it within their Mars environmental simulation chamber, which is specially designed to mimic conditions on the fourth planet from the sun -- right down to its infamous Martian dust.
Variations in the stuff that cements grains together in sandstone have shaped the landscape surrounding NASA's Curiosity Mars rover and could be a study topic at the mission's next science waypoint.
A comparison of images taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter in November 2010 and May 2013 reveal the formation of a new gully channel on a crater-wall slope in the southern highlands of Mars.
Two distinct volcanic eruptions have flooded this area of Daedalia Planum with lava, flowing around an elevated fragment of ancient terrain. The images were acquired by ESA’s Mars Express on 28 November 2013 towards the eastern boundary of the gigantic Tharsis Montes volcanic region, where the largest volcanoes on Mars are found.
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.
