Phobos was the primary object of study for the Phobos 1 spacecraft. Phobos 1 was an uncrewed Soviet space probe of the Phobos Program launched from the Baikonour launch facility on 7 July 1988. [1] Its intended mission was to explore Mars and its moons Phobos and Deimos. The mission failed on 2 September 1988 when a computer malfunction caused ...
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 (/ 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.
Fobos-Grunt was an intended interplanetary probe that included a lander to study Phobos and a sample return vehicle to return a sample of about 200 g (7.1 oz) of soil to Earth. [1] It was also to study Mars from orbit, including its atmosphere and dust storms, plasma and radiation.
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 ...
Phobos (Ancient Greek: Φόβος, lit. 'flight, fright', [1] pronounced, Latin: Phobus) is the god and personification of fear and panic in Greek mythology. Phobos was the son of Ares and Aphrodite, and the brother of Deimos. He does not have a major role in mythology outside of being his father's attendant. [2]
In this context, he voiced a suggestion that Phobos might be hollow, and possibly of artificial origin. This interpretation has since been refuted by more detailed study, but the apparent suggestion of extraterrestrial involvement caught the public imagination, though there is some disagreement as to how seriously Shklovsky intended the idea to ...
After failure of the second fourth-stage burn, the probe assembly re-entered the Earth's atmosphere, breaking up over a 320 km (200 mi) long portion of the Pacific Ocean, Chile, and Bolivia. [1] The Mars 96 spacecraft was based on the Phobos probes launched to Mars in 1988. They were of a new design at the time and both ultimately failed.
