The Mars monolith as seen from orbit. 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] The HiRISE camera that was used to photograph the monolith has a resolution of approximately 1 foot ...
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. [2] [3] A monolith is a geological feature consisting of a single massive piece of rock
The Phobos monolith (right of center) as taken by the Mars Global Surveyor (MOC Image 55103, 1998) In 2007, the Canadian Space Agency funded a study by Optech and the Mars Institute for an uncrewed mission to Phobos known as Phobos Reconnaissance and International Mars Exploration (PRIME).
In November of that year, a similar metal monolith was found deep in the Mars-like landscape of Utah's red-rock desert. Then came sightings in Romania, central California and on the famed Fremont ...
Valles Marineris (/ ˈ v æ l ɪ s m ær ɪ ˈ n ɛər ɪ s /; [1] Latin for Mariner Valleys, named after the Mariner 9 Mars orbiter of 1971–72 which discovered it) is a system of canyons that runs along the Martian surface east of the Tharsis region. [2]
Ares Vallis / ˈ ɛər iː z ˈ v æ l ɪ s / is an outflow channel on Mars, named after the Greek name for Mars: Ares, the god of war; it appears to have been carved by fluids, perhaps water.
This means that Mars has lost a volume of water 6.5 times what is stored in today's polar caps. The water for a time would have formed an ocean in the low-lying Mare Boreum. The amount of water could have covered the planet about 140 meters, but was probably in an ocean that in places would be almost 1 mile deep.
Composite demonstrating relative resolution of seven different cameras that imaged Mars: HiRISE (Mars Reconnaissance Orbiter), THEMIS VIS (Mars Odyssey), MOC-WAC (Mars Global Surveyor), HRSC (Mars Express), CTX (Mars Reconnaissance Orbiter), Viking, Mariner 4. Location is Memnonia quadrangle.
