Phobos probe. 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 (/ ˈ f oʊ b ə s /; systematic designation: Mars I) is the innermost and larger of the two natural satellites of Mars, the other being Deimos. The two moons were discovered in 1877 by American astronomer Asaph Hall. Phobos is named after the Greek god of fear and panic, who is the son of Ares (Mars) and twin brother of Deimos.
Phobos has a diameter of 22.2 km (13.8 mi) and a mass of 1.08 × 10 16 kg, while Deimos measures 12.6 km (7.8 mi) across, with a mass of 1.5 × 10 15 kg. Phobos orbits closer to Mars, with a semi-major axis of 9,377 km (5,827 mi) and an orbital period of 7.66 hours; while Deimos orbits farther with a semi-major axis of 23,460 km (14,580 mi) and ...
(also known as Leather Goddesses 2 or LGOP2) is a graphic adventure game written by Steve Meretzky and published by Activision in 1992 under the Infocom label. LGOP2 is the sequel to the 1986 interactive fiction game Leather Goddesses of Phobos, also written by Meretzky.
Leather Goddesses of Phobos bore a difficulty rating of "Standard". The game has 75 locations, including the maze known as the catacombs, the planets Mars and Venus (which must be explored extensively), outer space, and the city of Cleveland, which is a single location with one building and two exits.

The last successful interplanetary missions were the Soviet Vega 2 in 1985–1986, and the partially successful Phobos 2 in 1988–1989. [11] Fobos-Grunt was designed to become the first spacecraft to return a macroscopic sample from an extraterrestrial body since Luna 24 in 1976.
There are two models for the age of Stickney, based on the differing possible dates at which Phobos began to orbit around Mars. If Phobos has been orbiting for 4.3 Ga (billion years) then Stickney formed 4.2 Ga ago, but if Phobos has only been orbiting for 3.5 Ga then it formed 2.6 Ga ago. [4]
