Phobos 2 investigated the Mars surface and atmosphere and returned 37 images of Phobos [3] with a resolution of up to 40 meters. Shortly before the final phase of the mission, during which the spacecraft was to approach within 50 m of Phobos' surface and release two landers (one, a mobile hopper , the other, a stationary platform) contact with ...
The Phobos program (Russian: Фобос, Fobos, Greek: Φόβος) was an uncrewed space mission consisting of two probes launched by the Soviet Union to study Mars and its moons Phobos and Deimos. Phobos 1 was launched on 7 July 1988, and Phobos 2 on 12 July 1988, each aboard a Proton-K rocket. [1] Phobos 1 suffered a terminal failure en route ...

Phobos could be a second-generation Solar System object that coalesced in orbit after Mars formed, rather than forming concurrently out of the same birth cloud as Mars. [36] 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 planetesimal. [37]
Fobos-Grunt or Phobos-Grunt (Russian: Фобос-Грунт, where грунт refers to the ground in the narrow geological meaning of any type of soil or rock exposed on the surface) was an attempted Russian sample return mission to Phobos, one of the moons of Mars.
Use of NASA logos, insignia and emblems is restricted per U.S. law 14 CFR 1221.; The NASA website hosts a large number of images from the Soviet/Russian space agency, and other non-American space agencies.
Phobos is named after the Greek god of fear and panic, who is the son of Ares (Mars) and twin brother of Deimos. Phobos is a small, irregularly shaped object with a mean radius of 11 km (7 mi). It orbits 6,000 km (3,700 mi) from the Martian surface, closer to its primary body than any other known natural satellite to a planet.
The crater is named after mathematician Chloe Angeline Stickney Hall, the wife of Phobos' discoverer Asaph Hall, whose support was credited by her husband as critical for his discovery of the moon. [ 1 ] [ 2 ] The crater was named in 1973, based on Mariner 9 images, by an IAU nomenclature committee chaired by Carl Sagan .
