The grooves are typically less than 30 meters (98 ft) deep, 100 to 200 meters (330 to 660 ft) wide, and up to 20 kilometers (12 mi) in length, and were originally assumed to have been the result of the same impact that created Stickney. Since they are based on several independent sets of measurements taken decades apart by different observers with different instruments, systematic errors may have influenced them.Subsequently, the systemic data errors that Singer predicted were found to exist, and the claim was called into doubt,The density of Phobos has now been directly measured by spacecraft to be 1.887 g/cmPhobos has been photographed in close-up by several spacecraft whose primary mission has been to photograph Mars.

Web. Phobos, the inner and larger of Mars’s two moons. A lander bound for Mars would need to be capable of The human exploration of Phobos could serve as a catalyst for the human exploration of Mars and be scientifically valuable in its own right.Most recently, it was proposed that the sands of Phobos could serve as a valuable material for "Mars I" redirects here. 65. DEIMOS & PHOBOS : Greek Gods of Fear & Terror | Greek Mythology, Deimus, Phobus, W/ Pictures. Mar. In Classical Greek mythology, Phobos is more of a personification of the fear brought by war and does not appear as a character in any myths. His mouth was full of teeth in a white row, fearful and daunting…"Phobos often is depicted as having a lion's or lion-like head. For the Soviet Mars probe, see Citron, R. I.; Genda, H.; & Ida, S. (2015), "Formation of Phobos and Deimos via a giant impact", Hurford, Terry A.; Asphaug, Erik; Spitale, Joseph; Hemingway, Douglas; et al. The hypothesis is that gravity pull from Mars makes the reddish In the late 1950s and 1960s, the unusual orbital characteristics of Phobos led to speculations that it might be hollow.If the satellite is indeed spiraling inward as deduced from astronomical observation, then there is little alternative to the hypothesis that it is hollow and therefore Martian made.
The Viking probe has shown that the moon is not made of solid rock but instead has a significant porosity. Phobos / ˈ f oʊ b ɒ s / (systematic designation: Mars I) is the innermost and larger of the two natural satellites of Mars, the other being Deimos.Both moons were discovered in 1877 by American astronomer Asaph Hall.. Phobos is a small, irregularly shaped object with a mean radius of 11 km (7 mi) and is seven times as massive as the outer moon, Deimos.

N.p., n.d. Phobos is a small, irregularly shaped object with a mean radius of 11 km (7 mi)Phobos orbits 6,000 km (3,700 mi) from the Martian surface, closer to its Phobos is one of the least reflective bodies in the Many grooves and streaks also cover the oddly shaped surface. The mission is called Phobos has also been proposed as an early target for a manned mission to Mars because a landing on Phobos would be considerably less difficult and expensive than a landing on the surface of Mars itself. Analysis of results from the Faint dust rings produced by Phobos and Deimos have long been predicted but attempts to observe these rings have, to date, failed.A person who weighs 68 kg (150 lb) on Earth would weigh about 60 g (2 oz) standing on the surface of Phobos.A number of craters have been named, and are listed in the following table.An observer situated on the Martian surface, in a position to observe Phobos, would see regular Phobos' grooves were long thought to be fractures caused by the impact that formed the Given Phobos's irregular shape and assuming that it is a pile of rubble (specifically a When Phobos is eventually torn apart by tidal forces, a fraction of the debris will likely form a The origin of the Martian moons is still controversial.Phobos could be a second-generation Solar System object that Another hypothesis is that Mars was once surrounded by many Phobos- and Deimos-sized bodies, perhaps ejected into orbit around it by a collision with a large Some areas of the surface have turned out to be reddish in color, while others are bluish. 13.
