NASA's Mars rover Curiosity has placed its drill onto a series of four locations on a Martian rock and pressed down on it with the rover's arm, in preparation for using the drill in coming days.
Networks of narrow ridges found in impact craters on Mars appear to be the fossilized remnants of underground cracks through which water once flowed, according to a new analysis by researchers from Brown University.
Controllers of NASA's Mars rover Curiosity say they are considering a smoother path across a small sand dune to reach a favorable route to science destinations.
Spring is a dynamic season on the dunes surrounding Mars' north pole. When frozen carbon dioxide, or dry ice, deposited as a winter ice cap on Mars…
Opportunity is on the inboard edge of "Cape York" on the rim of Endeavour Crater, performing an in-situ (contact) science investigation of veins in…
Researchers using NASA's Mars Reconnaissance Orbiter see seasonal changes on far-northern Martian sand dunes caused by warming of a winter blanket of frozen carbon dioxide.
Scientists believe that a large crater, which has been discovered on Mars, might have been a lake several billion years ago.
NASA's Mars rover Curiosity has for the first time used the camera on its arm to take photos at night, illuminated by white lights and ultraviolet lights on the instrument.
ESA's Mars Express imaged the striking upper part of the Reull Vallis region of Mars with its high-resolution stereo camera last year.
NASA's Mars Exploration Rover Opportunity, one of the twin rovers that bounced to airbag-cushioned safe landings on Mars nine years ago this week, is currently examining veined rocks on the rim of an ancient crater.
Opportunity is on the inboard edge of "Cape York" on the rim of Endeavour Crater, now engaged in in-situ (contact) science investigation of veins in the light-toned outcrop "Whitewater Lake," a place the rover visited previously.
The subsurface environment on Mars may hold clues to the origin of life, scientists argue in a recently published research article led by Planetary Science Institute's Joseph Michalski.
A NASA spacecraft is providing new evidence of a wet underground environment on Mars that adds to an increasingly complex picture of the Red Planet's early evolution.
A US spacecraft orbiting Mars has provided evidence of an ancient crater lake fed by groundwater, adding further support to theories that the Red Planet may once have hosted life, NASA said Sunday.
When humans eventually travel to the Red Planet, the voyage will be long and difficult.
A European spacecraft has captured a striking image of a river-like structure on Mars believe formed when running water flowed in the distant martian past.
