Latest Spirit rover Stories
Curiosity got to witness an Earth-like experience on the Martian surface last week, by watching the moon Phobos create an eclipse on Mars.
NASA's Mars Exploration Rovers Spirit and Opportunity teams are slated to receive the Haley Space Flight Award.
"What you've accomplished embodies the American spirit." This praise came from President Barack Obama in a phone call to the operations team, in which he lauded NASA's "incredibly impressive" mission in landing the Curiosity rover on Mars last week.
NASA is releasing even more photographs taken by the Curiosity rover during its first week of service on the Red Planet.
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...
