Rocks On Mars
This is an alphabetical list of named rocks (and meteorites) found on Mars, by mission. This list is a sampling of rocks viewed, and is not an exhaustive listing. A more complete listing may be found on the various NASA mission web sites. This listing does ''not'' include Martian meteorites found on Earth. Names for Mars rocks are largely unofficial designations used for ease of discussion purposes, as the International Astronomical Union's official Martian naming system declares that objects smaller than are not to be given official names. Because of this, some less significant rocks seen in photos returned by Mars rovers have been named more than once, and others have even had their names changed later due to conflicts or even matters of opinion. Often rocks are named after the children or family members of astronauts or NASA employees. The name ''Jazzy'', for example, was taken from a girl named Jazzy who grew up in Grand Junction, CO, USA. Her father worked for NASA and co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meteorite
A meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or Natural satellite, moon. When the original object enters the atmosphere, various factors such as friction, pressure, and chemical interactions with the atmospheric gases cause it to heat up and radiate energy. It then becomes a meteor and forms a Meteoroid#Fireball, fireball, also known as a shooting star; astronomers call the brightest examples "Bolide#Astronomy, bolides". Once it settles on the larger body's surface, the meteor becomes a meteorite. Meteorites vary greatly in size. For geologists, a bolide is a meteorite large enough to create an impact crater. Meteorites that are recovered after being observed as they transit the atmosphere and Impact event, impact the Earth are called meteorite falls. All others are known as meteorite finds. Meteorites have traditiona ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adirondack (Mars)
Adirondack is the nickname for Mars Exploration Rover ''Spirit'''s first target rock. Scientists chose Adirondack to be ''Spirit''s first target rock after considering another, called Sashimi, that would have been a shorter, straight-ahead drive. ''Spirit'' traversed the sandy martian terrain at Gusev Crater to arrive in front of this football-sized rock on January 18, 2004, just three days after it successfully rolled off the lander. Scientists named the angular rock after the Adirondack mountain range in New York. The name "Adirondacks" is an Anglicized version of the Mohawk ''ratirontaks'', meaning "they eat trees", a derogatory name which the Mohawk historically applied to the Algonquian-speaking tribes of the Adirondack Mountains; when food was scarce, the Algonquians would eat the buds and bark of trees. The rock was selected as ''Spirit''s first target because its dust-free, flat surface was ideally suited for grinding. Clean surfaces also are better for examining a r ...

Heat Shield Rock
Heat Shield Rock is a basketball-sized iron-nickel meteorite found on the Meridiani Planum plain of Mars by the Mars rover ''Opportunity'' in January 2005. Informally referred to as "Heat Shield Rock" by the Opportunity research team, the meteorite was formally named Meridiani Planum meteorite by the Meteoritical Society in October 2005 (meteorites are always named after the place where they were found). Discovery ''Opportunity'' encountered the meteorite entirely by chance, in the vicinity of its own discarded heat shield (hence the name). ''Opportunity'' had been sent to examine the heat shield after exiting the crater Endurance. This was the first meteorite found on another planet and the third found on another Solar System bodytwo others, the millimeter-sized Bench Crater and Hadley Rille meteorites, were found on the Moon. Analysis The rock was initially identified as unusual in that it showed, from the analysis with the Mini-TES spectrometer, an infrared spectrum t ...

Opportunity Mission Timeline
''Opportunity'' is a robotic rover that was active on the planet Mars from 2004 to 2018. Launched on July 7, 2003, ''Opportunity'' landed on Mars' Meridiani Planum on January 25, 2004, at 05:05 Ground UTC (about 13:15 Mars local time), three weeks after its twin ''Spirit'' (MER-A), also part of NASA's Mars Exploration Rover Mission, touched down on the other side of the planet."Spirit" landed on January 4, 2004. While ''Spirit'' became immobile in 2009 and ceased communications in 2010, ''Opportunity'' exceeded its planned 90 sol (Martian days) duration of activity by 14 years 46 days (in Earth time). ''Opportunity'' continued to move, gather scientific observations, and report back to Earth until 2018. What follows is a summary of events during its continuing mission. ''Opportunity'' started in Eagle crater in 2004, literally landing inside on the crater basin, then it travelled outward making its way to Endurance crater. After this it went to Victoria crater, all the way m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
El Capitan (Mars)
El Capitan is a layered rock outcrop found within the Margaritifer Sinus quadrangle (MC-19) region of the planet Mars, this geological outcrop was first discovered and observed by the Mars Exploration Rover ''Opportunity'' in February 2004. The rock outcrop was named for El Capitan, a topographical mountain lying within the state, Texas.

Bounce Rock
Bounce Rock is a football-sized primarily pyroxene rock found within the Meridiani Planum of the planet Mars. It was discovered and observed by the Mars Exploration Rover ''Opportunity'' in April 2004. The rock was named for it having been struck by ''Opportunity'' as the craft bounced to a stop during its landing stage. Bounce Rock bears a striking resemblance to a class of meteorites found on Earth known as shergottites, that are believed to have originated from Mars. Bopolu (crater) Bopolu is an impact crater located within the Meridiani Planum extraterrestrial plain of Mars. Bopulu was seen by ''Opportunity'' rover in 2010 in the distance, and with some of its rim visible. Bopoplu was officially named in 2006 along with 31 ... was identified as a possible source of Bounce rock.

Block Island Meteorite
Block Island meteorite, officially. named Meridiani Planum 006 shortened as MP 006, was found on Mars by the ''Opportunity'' rover on July 17, 2009. It is about across. History Block Island was the first of three iron meteorites encountered by the rover on Meridiani Planum within a few hundred meters, the others being Shelter Island (the second meteorite found), and Mackinac Island (the third one found). No strong evidence exists concerning when Block Island may have fallen on Mars, though atmospheric conditions would have favored its arrival in the late Noachian period. Block Island may be extensively weathered, or conversely the features covering it may simply be the regmaglypts formed by its passage through the atmosphere. Contrary to some claims, Block Island is not too large for the modern martian atmosphere to produce, though the denser the atmosphere the more effectively it would produce Block Island mass meteorites.

Opportunity (rover)
''Opportunity'', also known as MER-B (Mars Exploration Rover – B) or MER-1, is a robotic rover that was active on Mars from 2004 until 2018. ''Opportunity'' was operational on Mars for sols (). Launched on July 7, 2003, as part of NASA's Mars Exploration Rover program, it landed in Meridiani Planum on January 25, 2004, three weeks after its twin, ''Spirit'' (MER-A), touched down on the other side of the planet. With a planned 90- sol duration of activity (slightly less than 92.5 Earth days), ''Spirit'' functioned until it got stuck in 2009 and ceased communications in 2010, while ''Opportunity'' was able to stay operational for sols after landing, maintaining its power and key systems through continual recharging of its batteries using solar power, and hibernating during events such as dust storms to save power. This careful operation allowed ''Opportunity'' to operate for 57 times its designed lifespan, exceeding the initial plan by (in Earth time). By June 10, 2018, when ...

Gusev (Martian Crater)
Gusev is a crater on the planet Mars and is located at and is in the Aeolis quadrangle. The crater is about 166 kilometers in diameter and formed approximately three to four billion years ago. It was named after Russian astronomer Matvey Gusev (1826–1866) in 1976. Prior to the exploration of the crater by the Spirit Rover, the crater was postulated to be an ancient lakebed with Ma'adim Vallis draining into it, of volcaniclastic origin, or a combination of both. These interpretations were based on ''Viking'' orbiter imagery, MOC imagery, THEMIS thermal mapping, and MOLA elevation mapping. However, Spirit did not find any lacustrine deposits, instead Spirit found alkaline volcanic rocks, including olivine basalt, comminuted basaltic debris, lavas, and pyroclastic rocks, but no eruption centers. More recently, satellite images showed the trails of dust devils on Gusev's floor. The ''Spirit'' rover later photographed dust devils from the ground, and likely owes much o ...

Rock Outcrop
An outcrop or rocky outcrop is a visible exposure of bedrock or ancient superficial deposits on the surface of the Earth. Features Outcrops do not cover the majority of the Earth's land surface because in most places the bedrock or superficial deposits are covered by soil and vegetation and cannot be seen or examined closely. However, in places where the overlying cover is removed through erosion or tectonic uplift, the rock may be exposed, or ''crop out''. Such exposure will happen most frequently in areas where erosion is rapid and exceeds the weathering rate such as on steep hillsides, mountain ridges and tops, river banks, and tectonically active areas. In Finland, glacial erosion during the last glacial maximum (ca. 11000 BC), followed by scouring by sea waves, followed by isostatic uplift has produced many smooth coastal and littoral outcrops. Bedrock and superficial deposits may also be exposed at the Earth's surface due to human excavations such as quarrying and build ...

Spirit (rover)
''Spirit'', also known as MER-A (Mars Exploration Rover – A) or MER-2, is a Mars Rover, Mars robotic rover, active from 2004 to 2010. ''Spirit'' was operational on Mars for Timekeeping on Mars#Sols, sols or 3.3 Martian years ( days; '). It was one of two rover (space exploration), rovers of NASA's Mars Exploration Rover Mission managed by the Jet Propulsion Laboratory (JPL). Spirit landed successfully within the impact crater Gusev (Martian crater), Gusev on Mars at 04:35 Ground UTC on January 4, 2004, three weeks before its twin, ''Opportunity (rover), Opportunity'' (MER-B), which landed on the other side of the planet. Its name was chosen through a Sofi Collis, NASA-sponsored student essay competition. The rover got stuck in a "sand trap" in late 2009 at an angle that hampered recharging of its batteries; its last communication with Earth was on March 22, 2010. The rover completed its planned 90-Martian day, sol mission (slightly less than 92.5 Earth days). Aided by cleani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
