Phobos is the larger and innermost of Mars' two moonss, named after Phobos, son of Ares (Mars) from Greek Mythology.
Phobos was discovered on August 18, 1877 at about 09:14 UTC (given in contemporary sources as "August 17 16:06" Washington mean time using the old astronomical convention of beginning a day at noon, so 12 hours must be added to get the actual local mean time).
Phobos was first photographed close-up by Mariner 9 in 1971, Viking 1 in 1977, Phobos 2 in 1988, and by Mars Global Surveyor in 1998 and 2003.

Phobos ("FOH bus") is the larger and innermost of Mars' two moons.
Phobos and Deimos may be composed of carbon-rich rock like C-type asteroids.
Phobos and Deimos may someday be useful as "space stations" from which to study Mars or as intermediate stops to and from the Martian surface; especially if the presence of ice is confirmed.

 Mars' Moon Phobos
Phobos [FOH-bohs] (fear) is a moon of Mars and was named after an attendant of the Roman war god Mars.
Phobos shows striated patterns which are probably cracks caused by the impact event of the largest crater on the moon.
Because Phobos is only 28 by 20 kilometers (17 by 12 miles), the moon must have been nearly shattered from the force of the impact that caused the giant crater.

data indicate that the surface temperature in the shadowed region of Phobos is -170° F (-112° C), while a few kilometers away (on the sunlit side of Phobos) the temperature is +25° F (-4 ° C).
The extreme temperature differences between the night and day sides of Phobos indicate that the surface is composed of very small particles that lose their heat rapidly once the Sun sets.
Phobos, the inner and larger of the two moons of Mars, was the subject of several close observations taken by the Mars Global Surveyor during the past month.

 Mars Global Surveyor MOC2-187 Release
Phobos and the smaller, more distant satellite, Deimos, were discovered in 1877 by Asaph Hall, an astronomer at the United States Naval Observatory in Washington, D.C. Hall had been hunting for martian satellites for some time, and was about to abandon the search when he was encouraged by his wife to continue.
Phobos was the target of the ill-fated Phobos 1 and Phobos 2 spacecraft, launched by the Soviet Union in 1988.
Phobos 2 actually reached Mars in 1989 and obtained a few pictures of the satellite---it also captured the shadow of Phobos cast upon the martian surface using its thermal infrared imager, Termoskan.

Phobos is slowly falling down to Mars and is expected to crash into the planet in the next few million years.
Phobos is locked in a so-called "death spiral", which means it is in an orbit that is gradually pulling it on a collision course with the surface of the planet.
The moon appears to be composed of C-type rock, similar to flish carbonaceous chondrite asteroids.

Both moons are tidally locked with Mars — that is, the same face of each moon always faces the planet, just as the same side of our own moon always faces Earth.
Many scientists believe that Phobos and Deimos are asteroids that wandered close to Mars billions of years ago.
But other scientists say that the moons formed at the same time as Mars, or that they're the remnants of a larger moon that was shattered by a collision with a large meteor.

 Mars Global Surveyor MOC2-400 Release
The wide angle images illustrate the fact that Phobos is mostly colorless (dark gray); the faint orange/red hue in the wide angle picture is a combination of slight differences in the focal lengths of the blue and red cameras and the orange/red illumination provided by reflection of sunlight off Mars.
This is a part of Phobos that was not seen by MOC in 1998, when MGS made several close flybys of the tiny moon.
The rows of grooves and aligned pits on Phobos are related to, and were probably caused by, a large meteor impact that occurred on the side of Phobos that is not seen here.

Phobos is locked in a "death spiral" around Mars, and it'll eventually crash into the planet, or be torn apart and turned into a short-lived ring.
This tiny moon is thought to be in a ‘death spiral’, slowly orbiting toward the surface of Mars.
Eventually Phobos could be torn apart by Martian gravity and become a short-lived ring around Mars, or even impact on the surface.

Phobos could have been a quasi moon that had only gotten that close to mars every 50 thousand years or so.
Upon completing an orbit, the moon again enters what remains of the debris field, so expecting a lower density of striations, but interacts in the direction of orbit instead of normal to it in the first encounter.
The possibility that one moon is part of the impactor and the other moon is part of the impacted is not impossible but unlikely to produce enough combined momentum for the center of mass to cross Marsorbit.
