Meridiani Planum
The Meridiani Planum (alternately Meridiani plain, Meridiani plains, Terra Meridiani, or Terra Meridiani plains) is either a large plain straddling the equator of Mars and covered with a vast number of spherules containing a lot of iron oxide or a region centered on this plain that includes some adjoining land. The plain sits on top of an enormous body of sediments that contains a lot of bound water. The iron oxide in the spherules is crystalline (grey) hematite (Fe203). 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 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 spherules composed mainly of grey-hematite that sit loosely on top of the plain's soils and underneath ...

Daniel S
Daniel is a masculine given name and a surname of Hebrew origin. It means "God is my judge"Hanks, Hardcastle and Hodges, ''Oxford Dictionary of First Names'', Oxford University Press, 2nd edition, , p. 68. (cf. Gabriel—"God is my strength"), and derives from two early biblical figures, primary among them Daniel from the Book of Daniel. It is a common given name for males, and is also used as a surname. It is also the basis for various derived given names and surnames. Background The name evolved into over 100 different spellings in countries around the world. Nicknames (Dan, Danny) are common in both English and Hebrew; "Dan" may also be a complete given name rather than a nickname. The name "Daniil" (Даниил) is common in Russia. Feminine versions (Danielle, Danièle, Daniela, Daniella, Dani, Danitza) are prevalent as well. It has been particularly well-used in Ireland. The Dutch names "Daan" and "Daniël" are also variations of Daniel. A related surname developed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schiaparelli EDM
''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 re ...

Mars Surveyor 2001
The Mars Surveyor 2001 project was a multi-part Mars exploration mission intended as a follow-up to Mars Surveyor '98. After the two probes of the 1998 project, Mars Climate Orbiter and Mars Polar Lander, were both lost, NASA's "better, faster, cheaper" exploration philosophy was re-evaluated, with a particular eye on the two 2001 project probes. As a result, the mission, along with the launch of its lander and rover, were canceled in May 2000, but the decision was made to continue development with its orbiter counterpart. The orbiter launched as ''2001 Mars Odyssey'' in April 2001, in a mission independent of the Mars Surveyor project, and reached Mars in October 2001. After being placed in a cleanroom in 2001 and stored since, the nearly-completed lander component was eventually reused to fly the '' Phoenix'' mission, which launched in August 2007 and landed successfully on Mars in May 2008. Spacecraft Orbiter Lander The 2001 Surveyor lander spacecraft was built und ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Space Shuttle Challenger
Space Shuttle ''Challenger'' (OV-099) was a Space Shuttle orbiter manufactured by Rockwell International and operated by NASA. Named after the commanding ship of a nineteenth-century scientific expedition that traveled the world, ''Challenger'' was the second Space Shuttle orbiter to fly into space after '' Columbia'', and launched on its maiden flight in April 1983. It was destroyed in January 1986 soon after launch in an accident that killed all seven crewmembers aboard. Initially manufactured as a test article not intended for spaceflight, it was utilized for ground testing of the Space Shuttle orbiter's structural design. However, after NASA found that their original plan to upgrade ''Enterprise'' for spaceflight would be more expensive than upgrading ''Challenger'', the orbiter was pressed into operational service in the Space Shuttle program. Lessons learned from the first orbital flights of ''Columbia'' led to ''Challenger''s design possessing fewer thermal protectio ...

Eagle Crater
Eagle is a 22-metre long impact crater located on the Meridiani Planum extraterrestrial plain, situated within the Margaritifer Sinus quadrangle (MC-19) portion of the planet Mars. The Opportunity rover, ''Opportunity'' rover came to rest inside Eagle crater when it landed in 2004. Scientists were delighted that the rover landed there, as the crater contains Opportunity mission timeline#"Opportunity Ledge" outcroppings, rocky outcroppings that helped prove that Meridiani was once an ocean floor. This crater should not be confused with the other, much larger Martian crater ''Eagle (Acidalia Planitia crater), Eagle'', which was officially named by IAU's Working Group for Planetary System Nomenclature in 1976. Name The name is a triple reference: in honor of the first crewed spacecraft to land on the Moon in 1969; in honor of the launching country, the United States, whose symbol is an eagle; and in reference to the golf term ''eagle (golf), eagle'', referring to sinking a bal ...

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. It is hoped that the data ''Odyssey'' obtains will help answer the question of whether life 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, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Mars Exploration Rover
NASA's Mars Exploration Rover (MER) mission was a robotic space mission involving two Mars rovers, ''Spirit (rover), Spirit'' and ''Opportunity (rover), Opportunity'', exploring the planet Mars. It began in 2003 with the launch of the two rover (space exploration), rovers to explore the Martian surface and Geology of Mars, geology; both landed on Mars at separate locations in January 2004. Both rovers far outlived their planned missions of 90 Timekeeping on Mars#Sols, Martian solar days: MER-A ''Spirit'' was active until March 22, 2010, while MER-B ''Opportunity'' was active until June 10, 2018. Objectives The mission's scientific objective was to search for and characterize a wide range of rock (geology), rocks and soils that hold clues to past Water on Mars, water activity on Mars. The mission is part of NASA's Mars Exploration Program, which includes three previous successful landers: the two Viking program landers in 1976 and Mars Pathfinder probe in 1997.
