Latest Moons of Mars Stories
Earlier this month, ESAâ€™s Mars Express performed a special maneuver to observe an unusual alignment of Jupiter and the martian moon Phobos.
A new Mars movie clip gives us a rover's-eye view of a bluish Martian sunset, while another clip shows the silhouette of the moon Phobos passing in front of the sun.
Scientists now have firm indications that the Martian satellite Phobos formed relatively near its current location via re-accretion of material blasted into Marsâ€™ orbit by some catastrophic event.
Images from the recent flyby of Phobos, on March 7, 2010, have been released today.
Mars Express encountered Phobos last night, smoothly skimming past at just 67 km, the closest any manmade object has ever approached Marsâ€™ enigmatic moon.
ESAâ€™s Mars Express will skim the surface of Marsâ€™ largest moon Phobos on Wednesday evening.
On March 3, 2010 Mars Express will make its closest ever approach to Phobos, the larger of the two Martian moons.
Today Mars Express began a series of flybys of Phobos, the largest moon of Mars.
On January 26, Mars Express completed its 7777th orbit around the Red Planet, an auspicious milestone as the satellite is readied for the closest-ever flyby of Phobos, scheduled for just a few weeks from now.
For the very first time, the martian moons Phobos and Deimos have been caught on camera together.
The Planet Mars -- in astronomy, 4th planet from the sun, with an orbit next in order beyond that of the earth. Physical Characteristics Mars has a striking red appearance, and in its most favorable position for viewing, when it is opposite the sun, it is twice as bright as Sirius, the brightest star. Mars has a diameter of 4,200 mi (6,800 km), just over half the diameter of the earth, and its mass is only 11% of the earth's mass. The planet has a very thin atmosphere consisting...
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...
