Bopolu (crater)
Bopolu is an impact crater located within the Meridiani Planum extraterrestrial plain of Mars. Bopulu was seen by Opportunity rover, ''Opportunity'' rover in 2010 in the distance, and with some of its rim visible. Bopoplu was officially named in 2006 along with 31 Mars craters. Research has indicated that the impact that is thought to have created Bopulu went so deep that it went through existing layers and ejected older material from Mars' Noachian period. Bopulu is a diameter wide crater south of the ''Opportunity'' MER-B landing site, a rover which operated in the region starting in 2004 and therefore resulted in greater exploration and study of craters in this region. Bopulu was identified as a possible source for the Bounce Rock ejecta fragment Bounce rock, which was examined by the MER-B rover, was found to be similar in composition to the shergottite class of Martian meteorite, Mars meteorite found on Earth (Meteorites found on Earth determined to be from Mars). Bopulu is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meridiani Planum
Meridiani Planum (alternatively Terra Meridiani) is a large plain straddling the equator of Mars. The plain sits on top of an enormous body of sediments that contains bound water. The iron oxide in the spherules is crystalline (grey) hematite (Fe2O3). The Meridiani Planum is one of the most thoroughly investigated regions of Mars. Many studies were carried out by the scientists involved with NASA's Opportunity (rover), Mars Exploration Rover (MER) ''Opportunity''. Two outstanding features found by these investigations are the actions of water flow and aqueous chemistry in this plain's geological history and, particularly specific to the plain, an abundance and ubiquity of small Martian spherules, spherules composed mainly of grey-hematite that sit loosely on top of the plain's soils and underneath embedded inside its sediments. The loose surface spherules were eroded out of the sediments. They are informally called Martian spherules, "blueberries". The plain's sediments have extre ...

Schiaparelli EDM Lander
''Schiaparelli'' EDM () was a failed Entry, Descent, and Landing Demonstrator Module (EDM) of the ExoMars programme—a joint mission of the European Space Agency (ESA) and the Russian Space Agency Roscosmos. It was built in Italy and was intended to test technology for future soft landings on the surface of Mars. It also had a limited but focused science payload that would have measured atmospheric electricity on Mars and local meteorological conditions. Launched together with the ExoMars Trace Gas Orbiter (TGO) on 14 March 2016, ''Schiaparelli'' attempted a landing on 19 October 2016. Telemetry signals from ''Schiaparelli'', monitored in real time by the Giant Metrewave Radio Telescope in India (and confirmed by ''Mars Express''), were lost about one minute from the surface during the final landing stages. On 21 October 2016, NASA released an image by the '' Mars Reconnaissance Orbiter'' showing what appears to be the lander's crash site. The telemetry data accumulated and r ...

Miyamoto (crater)
Miyamoto is a crater within the Margaritifer Sinus quadrangle (MC-19) region of the planet Mars, west of the Plains of Meridiani. It is wide. Its northeastern half is filled with rocks formed in the presence of water and include minerals of iron and sulfur, which likely settled on lake bottoms or in groundwater systems. In the southwestern half of the crater floor, erosion has stripped these materials away, revealing clays and other materials like those found in the most ancient Martian rocks. More than 3.5 billion years old, they date to the Noachian era at which time, liquid water was likely present at the surface and could have created an environment favorable to life. Miyamoto was considered as a possible landing site for the Mars Science Laboratory. Mars Science Laboratory Several sites in the Margaritifer Sinus quadrangle have been proposed as areas to send NASA's next major Mars rover, the Mars Science Laboratory. Miyamoto Crater was in the top seven sites chosen. Amon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iazu (crater)
Iazu is an impact crater in the Meridiani Planum extraterrestrial plain, within the Margaritifer Sinus quadrangle (MC-19) region of the planet Mars. It is about 7 km in diameter. It is close to the landing site of the Mars Exploration Rover-B '' Opportunity'', and its walls have been photographed by the spacecraft during its traverse to Endeavour Crater. At the time, the crater was about away. It was named in 2006 for Iazu, a village in Dâmbovița County, southern Romania. Bopolu (crater) is west of Iazu and Endeavour crater.

Endeavour (crater)
Endeavour is an impact crater located in the Meridiani Planum extraterrestrial plain within the Margaritifer Sinus quadrangle (MC-19) region of the planet Mars. Endeavour is about in diameter. Using ''Mars Reconnaissance Orbiter'' data, phyllosilicate-bearing outcrops have been detected along its rim. These minerals may have formed under wet conditions in a low-acidic environment during the early history of Mars. There are raised rim segments to the north, east, and southwest. The rim has become worn, rounded and degraded, with infilling of plains material in a manner similar to the Victoria crater. When compared to the surrounding plains, the crater floor shows an enhanced spectral signature of basalt and hematite. The interior contains two groups of dune fields. Images taken since 2008 show evidence of changes in some of the associated formations, which may be evidence of active erosion by the martian wind over a period of two to three years. The plains surrounding the rim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geography Of Mars
Areography, also known as the geography of Mars, is a subfield of planetary science that entails the delineation and characterization of regions on Mars. Areography is mainly focused on what is called physical geography on Earth; that is the distribution of physical features across Mars and their cartography, cartographic representations. In April 2023, ''The New York Times'' reported an updated global map of Mars based on images from the Hope Mars Mission, ''Hope'' spacecraft. A related, but much more detailed, global Mars map was released by NASA on 16 April 2023. History The first detailed observations of Mars were from ground-based telescopes. The history of these observations are marked by the opposition (astronomy), oppositions of Mars, when the planet is closest to Earth and hence is most easily visible, which occur every couple of years. Even more notable are the perihelic oppositions of Mars which occur approximately every 16 years, and are distinguished because Mars ...

List Of Craters On Mars
__NOTOC__ This is a list of craters on Mars. Impact craters on Mars larger than exist by the hundreds of thousands, but only about one thousand of them have names. Names are assigned by the International Astronomical Union after petitioning by relevant scientists, and in general, only craters that have a significant research interest are given names. Martian craters are named after famous scientists and science fiction authors, or if less than in diameter, after towns on Earth. Craters cannot be named for living people, and names for small craters are rarely intended to commemorate a specific town. Latitude and longitude are given as planetographic coordinates with west longitude. Catalog Martian craters are listed alphabetically on the following partial lists: * List of craters on Mars: A–G * List of craters on Mars: H–N * List of craters on Mars: O–Z Names are grouped into tables for each letter of the alphabet, containing the crater's name (linked if articl ...

2001 Mars Odyssey
''2001 Mars Odyssey'' is a robotic spacecraft orbiting the planet Mars. The project was developed by NASA, and contracted out to Lockheed Martin, with an expected cost for the entire mission of US$297 million. Its mission is to use spectrometers and a thermal imager to detect evidence of past or present water and ice, as well as study the planet's geology and radiation environment. The data ''Odyssey'' obtains is intended to help answer the question of whether life once existed on Mars and create a risk-assessment of the radiation that future astronauts on Mars might experience. It also acts as a relay for communications between the ''Curiosity'' rover, and previously the Mars Exploration Rovers and ''Phoenix'' lander, to Earth. The mission was named as a tribute to Arthur C. Clarke, evoking the name of his and Stanley Kubrick's 1968 film '' 2001: A Space Odyssey''. ''Odyssey'' was launched April 7, 2001, on a Delta II rocket from Cape Canaveral Air Force Station, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mars
Mars is the fourth planet from the Sun. It is also known as the "Red Planet", because of its orange-red appearance. Mars is a desert-like rocky planet with a tenuous carbon dioxide () atmosphere. At the average surface level the atmospheric pressure is a few thousandths of Earth's, atmospheric temperature ranges from and cosmic radiation is high. Mars retains some water, in the ground as well as thinly in the atmosphere, forming cirrus clouds, frost, larger polar regions of permafrost and ice caps (with seasonal snow), but no liquid surface water. Its surface gravity is roughly a third of Earth's or double that of the Moon. It is half as wide as Earth or twice the Moon, with a diameter of , and has a surface area the size of all the dry land of Earth. Fine dust is prevalent across the surface and the atmosphere, being picked up and spread at the low Martian gravity even by the weak wind of the tenuous atmosphere. The terrain of Mars roughly follows a north-south ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
