Latest Spirit rover Stories
NASA's Phoenix Mars Lander has ended operations after repeated attempts to contact the spacecraft were unsuccessful.
Earlier this month, Mars Exploration Project manager John Callas updated a NASA audience at the Marshall Space Flight Center about future prospects for the Mars rovers.
NASA's Mars Exploration Rover Project will pass a historic Martian longevity record on Thursday, May 20.
When some Mars explorers learned of plans for a worldwide photography event combining shots taken from thousands of different locations on May 2, 2010, they figured, "Why just one world?"
NASA's Jet Propulsion Laboratory said Wednesday that the sand-trapped Mars rover Spirit failed to make a scheduled communication this week and may have gone into a power-saving hibernation to survive the planet's winter.
The team that operates NASA's Mars rovers Spirit and Opportunity will receive the 2010 International Space Ops Award for Outstanding Achievement.
NASA's Mars Exploration Rover Opportunity today surpassed 20 kilometers (almost 13 miles) of total driving since it landed on Mars 74 months ago.
Weird coatings on rocks beside a young Martian crater remain puzzling after a preliminary look at data from examination of the site by NASA's Opportunity rover.
NASA's Mars Exploration Rover Opportunity, now in its seventh year on Mars, has a new capability to make its own choices about whether to make additional observations of rocks that it spots on arrival at a new location.
Several teacher workshops are being offered this spring and summer at the NASA/JPL Educator Resource Center in Pomona, Calif.
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...
