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). Phobos and Deimos are the only natural satellites of the terrestrial planets, other than our Moon. Or, the moons could have spawned from a violent birth, much like Earth's moon. Because of their odd shapes and strange composition, scientists thought for a long time that both moons were born asteroids. Rouse) (Greek epic C5th A.D.) : Frazer) (Roman poetry C1st B.C.

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 that the moon is breaking apart, one 2015 study said, although others have postulated these marks are instead grooves from Mars ejecta.

"The warrior himself has raised the war-cry and, inspired by Ares he raves for battle like a Bakkhe (Bacchante), with a look to inspire fear. À cause de sa proximité et de la faible inclinaison de son orbite, un observateur doit se trouver entre -82° et +82° de latitude pour l'observer[13]. This view of the Martian moons Phobos and Deimos comes from a set of photos taken by NASA's Mars rover Curiosity on Aug. 1, 2013, as Phobos (the larger one) passed in front of Deimos from Curiosity's perspective.
