Latest Spirit rover Stories
NASA said it has received 400 mission concepts from scientists and engineers for a future Mars mission. Scientists and engineers submitted their ideas to the Concepts and Approaches for Mars Exploration Workshop in Houston.
North Carolina State University researchers are proposing that a wind-driven "tumbleweed" Mars rover would be capable of moving across the Red Planet's rocky terrain.
Like a tourist waiting for just the right lighting to snap a favorite shot during a stay at the Grand Canyon, NASA's Mars Exploration Rover Opportunity has used a low sun angle for a memorable view of a large Martian crater.
With its daily supply of solar energy increasing, NASA's durable Mars Exploration Rover Opportunity has driven off the sunward-tilted outcrop, called Greeley Haven, where it worked during its fifth Martian winter.
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.
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. If...
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...
