Latest Spirit rover Stories
NASA has finally opened up its tightly sealed lips and said that its Curiosity rover has found evidence of simple organic compounds on Mars.
The European Space Agency's Mars Express has relayed scientific data from NASA's Curiosity rover for the first time.
It may not be in the company of little Martians, but NASA's Curiosity is determined to celebrate Thanksgiving this year with, or without, aliens to share it with.
New research published in the journal Earth and Planetary Science Letters shows that water once existed on Mars that was sufficiently warm enough to support life.
While it seems like Curiosity is the one getting all the headlines these days, NASA's "other" Mars rover, Opportunity, is still alive and well -- and en route to a new site to study the composition and internal structures of small spherical objects similar to the iron-rich ones previously discovered at its landing site.
NASA Administrator Charlie Bolden and Small Business Administration Administrator Karen Mills highlighted the contributions of small businesses to the success of the Curiosity rover's landing on Mars during a Google+ Hangout Wednesday with ATA Engineering, headquartered in Herndon, Va.
Curiosity got to witness an Earth-like experience on the Martian surface last week, by watching the moon Phobos create an eclipse on Mars.
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...
