With an altitude of 5,989 km (3,721 mi), Phobos orbits Mars below the synchronous orbit radius, meaning that it moves around Mars faster than Mars itself rotates. [23] Therefore, from the point of view of an observer on the surface of Mars, it rises in the west, moves comparatively rapidly across the sky (in 4 h 15 min or less) and sets in the ...
Curiosity's view of the Martian moons: Phobos passing in front of Deimos – in real-time (video-gif, 1 August 2013). Speculation about the existence of the moons of Mars had begun when the moons of Jupiter were discovered.
Observers on Mars can view transits of Phobos and transits of Deimos across the Sun. The transits of Phobos could also be called partial eclipses of the Sun by Phobos, since the angular diameter of Phobos is up to half the angular diameter of the Sun. However, in the case of Deimos the term "transit" is appropriate, since it appears as a small ...
Film Year Description 2036 Origin Unknown: 2018 After a mission to Mars results in a mysterious shuttle disappearance, mission controller Mackenzie “Mack” Wilson and an AI named ARTI discover a potentially alien cube on Mars that teleports to Earth, leading to revelations about the shuttle disaster, humanity's fate, and Mack's own identity within a cosmic intrigue.
A transit of Phobos from Mars usually lasts only thirty seconds or so, due to the moon's very rapid orbital period of approximately 7.6 hours. Because Phobos orbits close to Mars and in line with its equator, transits of Phobos occur somewhere on Mars on most days of the Martian year. Its orbital inclination is 1.08°, so the latitude of its ...
The Phobos monolith (right of center, casting long shadow) as taken by the Mars Global Surveyor (MOC Image 55103, 1998). The location of the monolith (HiRISE image PIA10368) The Phobos monolith is a large rock on the surface of Mars' moon Phobos. [1] It is a boulder, about 85 m (279 ft) across and 90 m (300 ft) tall.
The Mars monolith is a rectangular object, possibly a boulder, discovered on the surface of Mars. [ 1 ] [ 2 ] The Mars Reconnaissance Orbiter took pictures of it from orbit, roughly 180 miles (300 km) away. [ 1 ]
Laura's fiancé Allan and fellow astronaut Tony volunteer. They travel on the spaceship Meteor to Phobos, one of the two moons of Mars, where they launch the observation satellite. Tony finds an alien spaceship on Phobos. He and Allan are able to enter, finding an unconscious but still-living female alien.
