Latest Spirit rover Stories
Evidence that there was once water on Mars continues to mount, as the ESA and researchers from a U.S. university became the latest to tout findings supporting the theory.
NASA's Mars Exploration Rover Opportunity discovered evidence of ancient water at the rim of an ancient impact crater on the planet's surface, according to a new report published in the May 4 edition of the journal Science.
The Obama administration’s upcoming budget for NASA plans to cut $300 million out of the agency’s planetary science program, which could keep any planetary explorations, including Mars missions, grounded.
NASA said on Wednesday that a camera onboard its Mars Reconnaissance Orbiter recorded the first color image of Mars Exploration Rover Spirit's landing platform.
The camera at the end of the robotic arm on NASA's Mars rover Curiosity has its own calibration target, a smartphone-size plaque that looks like an eye chart supplemented with color chips and an attached penny.
According to new research, Mars may have been arid for over 600 million years, making it inhospitable for life to survive.
Eight years after landing on Mars for what was planned as a three-month mission, NASA's enduring Mars Exploration Rover Opportunity is working on what essentially became a new mission five months ago.
NASA's Mars Exploration Rover Opportunity will spend the next several months at a site informally named "Greeley Haven." The site is an outcrop that provides a sun-facing slope to aid in maintaining adequate solar power during the rover's fifth Martian winter.
Mars' Moon Deimos -- outermost of two small moons orbiting the planet Mars. Deimos orbits Mars at a distance of about 23,500 km (about 14,100 mi), completing an orbit once every 1.26 Earth days. The moon's orbit is almost circular and is only slightly tilted relative to the Martian equator. Deimos is irregular in shape, measuring about 15 km (about 9 mi) along its longest side and about 11 km (about 6.6 mi) along its shortest side. It is the smallest known moon in the solar system.

Mars' Moon Phobos -- in astronomy, innermost moon, or natural satellite, of Mars. Phobos orbits Mars at a distance of only 9,378 km (5,627 mi), closer to its planet than any other moon in the solar system. In fact, it is so close that the force of Mars's gravity is stronger than the force keeping the moon in its orbit, so the radius of Phobos's orbit is decreasing at the rate of about 1.8 m (about 6 ft) per century. In 40 million years, Phobos will either break apart into a ring...
