Latest Spirit rover Stories
NASA's most advanced mobile robotic laboratory, which will examine one of the most intriguing areas on Mars, is in final preparations for a launch from Florida's Space Coast at 10:25 a.m. EST (7:25 a.m. PST) on Nov. 25.
NASA Administrator Charles Bolden has named Cornell University Astronomy Professor Steven W. Squyres, as chairman of the NASA Advisory Council (NAC), an assembly of experts from various fields that offer guidance and policy advice to the administrator of America's space agency.
Researchers at the Caltech have directly determined the surface temperature of early Mars for the first time, providing evidence that's consistent with a warmer and wetter Martian past.
While NASA's Mars Exploration Rover Opportunity was traveling from Victoria crater to Endeavour crater, between September 2008 and August 2011, the rover team took an end-of-drive image on each Martian day that included a drive.
More than seven years after completing their three-month prime missions on opposite sides of Mars, NASA rovers Spirit and Opportunity have been selected for lifetime achievement award honors as part of the Breakthrough Awards presented by Popular Mechanics magazine.
Mars rover poised on rock that may yield yet more evidence of a wet Mars.
A view of a memorial to victims of the Sept. 11, 2001, attacks on the World Trade Center towers was taken on Mars yesterday, on the 10th anniversary of the attacks.
In September 2001, Honeybee Robotics employees in lower Manhattan were building a pair of tools for grinding weathered rinds off rocks on Mars, so that scientific instruments on NASA's Mars Exploration Rovers Spirit and Opportunity could inspect the rocks' interiors.
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...
