The origin of Phobos and Deimos, the two Martian moons, has been a mystery to astronomers. These two bodies are a fraction of the size and mass of the Moon, measuring just 22.7 km (14 mi) and 12.6 km ...

The Martian moon Phobos has a lumpy, nonspherical shape that suggests it may be a captured asteroid. (ESA/DLR/FU Berlin (G. Neukum)) The origin of the two small moons of Mars, called Phobos and Deimos ...

The long shallow grooves lining the surface of Phobos are likely early signs of the structural failure that will ultimately destroy this moon of Mars. Orbiting a mere 3,700 miles (6,000 kilometers) ...

The High Resolution Imaging Science Experiment, run from the University of Arizona, has produced a new color stereo view of Phobos, the larger and inner of Mars’ two tiny moons. The HiRISE camera ...

Phobos is the larger and innermost of Mars' two moons, and it's a fascinating celestial body. It's small, irregularly shaped, and orbiting just about 6,000 kilometers above the surface of the Red ...

Phobos is one of the two moons that revolve around Mars. It's a lumpy, crater-filled pile of rubble that measures only 10 by 14 by 11 miles (17 by 22 by 18 km). Phobos also orbits closer to Mars than ...

Phobos appears silhouetted against Mars between the colossal Tharsis volcanic province and the canyoned region spanning Noctis Labyrinthus and Valles Marineris.

Mars' largest moon, Phobos, has captured public imagination and been shrouded in mystery for decades. But numerical simulations recently conducted at Lawrence Livermore National Laboratory (LLNL) have ...

The doomed Martian moon Phobos, which is on a slow death spiral above the Red Planet, may hold some secrets about how Mars was formed. The moon's orbit of Mars — gradually degrading over the eons — ...

The 2020s are set to be a monumental decade for the search for life on Mars. Both NASA and the European Space Agency are operating or planning major missions to — and back from — the Red Planet in a ...
