Of the four rocky, terrestrial planets, only Mars has more than one moon. ; "Surface Evolution from Orbital Decay on Phobos", Division of Planetary Sciences of the American Astronomical Society meeting #47, National Harbor, MD, November 2015Black, Benjamin A.; and Mittal, Tushar; (2015), "The demise of Phobos and development of a Martian ring system", Burns, Joseph A.; "Contradictory Clues as to the Origin of the Martian Moons" in Landis, Geoffrey A.; "Origin of Martian Moons from Binary Asteroid Dissociation", Craddock, Robert A.; (1994); "The Origin of Phobos and Deimos", Lee, Pascal; Richards, Robert; Hildebrand, Alan; and the PRIME Mission Team 2008, "The PRIME (Phobos Reconnaissance and International Mars Exploration) Mission and Mars sample Return", in Lee, Pascal; Veverka, Joseph F.; Bellerose, Julie; Boucher, Marc; et al.
Like Phobos, Deimos is a small and lumpy, heavily cratered object. NY 10036. Its surface is marred by debris that may have come from impacts on Mars. Deimos Moon Facts. Benannt wurde er nach Phobos, dem Sohn und Begleiter des griechischen Kriegsgottes Ares (lat. Within 50 million years, the moon will either collide with Mars or become a ring of rubble around it; stretch marks on its surface are likely early signs "We think that Phobos has already started to fail, and the first sign of this failure is the production of these grooves," Terry Hurford, a research assistant at NASA's Goddard Space Flight Center in Maryland, who led a study about stretch marks, said in a Deimos, on the other hand, is slowly drifting away from the planet.While no mission has explored Phobos and Deimos as its primary objective, several spacecraft have snapped pictures during flybys. It took pictures of Deimos and Phobos from afar and showed that these were small moons that looked like potatoes.Several other orbiting spacecraft have performed long-range observations, including NASA's Viking orbiters (1970s and 1980s), the Soviet Phobos 2 mission (1980s), NASA's Mars Global Surveyor (1990s and 2000s), the European Mars Express mission (2000s), and NASA's MAVEN (Mars Atmosphere and Volatile Evolution mission). The orbit of Phobos is only 6000 kilometers away from the surface of the red planet.
The first was Another concept of a sample return mission from Phobos and Deimos is In March 2014, a Discovery class mission was proposed to place an orbiter in Mars orbit by 2021 to study Phobos and Deimos through a series of close flybys. The first was NASA's Mariner 9 spacecraft, which orbited the planet Mars starting in 1971. Phobos is slowly spiraling inward at a rate of 6 feet (1.8 meters) every century. ; 2010; "Hall: A Phobos and Deimos Sample Return Mission", Landis, Geoffrey A.; "Footsteps to Mars: an Incremental Approach to Mars Exploration", in Lee, Pascal; Braham, Stephen; Mungas, Greg; Silver, Matt; Thomas, Peter C.; and West, Michael D. (2005), "Phobos: A Critical Link Between Moon and Mars Exploration", Lee, Pascal (2007), "Phobos-Deimos ASAP: A Case for the Human Exploration of the Moons of Mars", An atmosphere could have slowed the pair down and settled them into their present-day orbits, but the air on the Martian planet is thin and insufficient for such a task.It is possible that the moons formed like the planet, from debris left over from the creation of Mars.

The clip includes interpolated frames smoothing out the motion between frames from Curiosity's Mast Camera… Phobos, von altgriechisch φόβος für „Furcht“, gesprochen [], ist einer der beiden Monde des Planeten Mars.Zusammen mit dem noch kleineren Deimos entdeckte ihn im Jahr 1877 der US-amerikanische Astronom Asaph Hall am US Naval Observatory.
