Phobos will crash into Mars
Phobos, satellite of Mars
|Automatic translation||Updated June 01, 2013|
The two moons of Mars are Phobos and Deimos.
NB: The names of its moons are an allusion to a Greek verse, "The God of war arrives, flanked by his two satellites (thugs) fear and terror" phobos is Greek for "fear", and Deimos 'terror'.
Image: Phobos is a highly irregular measures 27 × 21.6 × 18.8 km, it is also one of the smallest moons in the solar system. We see its crater Stickney feature, the bottom right of the photograph.
Phobos, the carbonaceous asteroid
Phobos and Deimos are very similar to C-type asteroids , i.e. carbonaceous asteroids. Scientists still do not understand how the planet Mars could gravitationally capture both asteroids and bring in the equatorial plane of the red planet. The image below shows against the very irregularly shaped Phobos observed by the Mars Express spacecraft of the European Space Agency at a flyover March 7, 2010. You can see many intersecting paths and a series of craters that are aligned much of the surface of the moon of Mars. Phobos looks like a conglomeration of debris in orbit and its mass is not enough important for gravity to have transformed into a sphere. The Russian Space Agency (RosKosmos) declared the PHOBOS-GRUNT mission as the first priority of its space science program to explore Phobos. PHOBOS-GRUNT mission is a technology demonstrator designed to test the ability to land and take off from Phobos. The mission will perform in situ observations from April 2013 for over a year. It will collect samples to be returned to Earth for analysis in July 2014.
Image: Overview of the images of Phobos, March 7, 2010, shows the moon rock from Mars in detail, with a resolution of only 4.4 meters per pixel. Astronomers know that Phobos is not a satellite solid throughout its area. Phobos does not form a single block, but a cluster of rocks. This view shows the potential landing sites for the next mission Phobos-Grunt 2011. NB: The C-type asteroids are carbonaceous asteroids whose variety is the most common (about 75% of known asteroids).
