Rhodes Scholar
The Rhodes Scholarship is an international postgraduate award for students to study at the University of Oxford, in the United Kingdom. Established in 1902, it is the oldest graduate scholarship in the world. It is considered among the world's most prestigious international scholarship programs. Its founder, Cecil John Rhodes, wanted to promote unity among English-speaking nations and instill a sense of civic-minded leadership and moral fortitude in future leaders, irrespective of their chosen career paths. Initially restricted to male applicants from countries that are today within the Commonwealth, Germany and the United States, the scholarship is now open to applicants from all backgrounds and genders around the world. Since its creation, controversy has surrounded its initial exclusion of women, its historical failure to select black Africans, and Cecil Rhodes's own standing as a British imperialist. Rhodes Scholars have achieved distinction as politicians, academics, sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Sirens Of Mars
''The Sirens of Mars'' is a 2020 non-fiction book by Sarah Stewart Johnson, focused on the search for life on Mars. Content and development The book combines elements of memoir from Johnson with the history and science of attempts to discover life on Mars. The book grew out of miscellaneous notes and observations written down by Johnson which she determined were valuable but not necessarily suitable for strictly scientific publications. Reception ''Kirkus Reviews ''Kirkus Reviews'' (or ''Kirkus Media'') is an American book review magazine founded in 1933 by Virginia Kirkus (1893–1980). The magazine is headquartered in New York City.

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] |
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 ...

Curiosity (rover)
''Curiosity'' is a car-sized Mars rover designed to explore the Gale crater on Mars as part of NASA's Mars Science Laboratory (MSL) mission. ''Curiosity'' was launched from Cape Canaveral (CCAFS) on November 26, 2011, at 15:02:00 UTC and landed on Aeolis Palus inside Gale crater on Mars on August 6, 2012, 05:17:57 UTC. The Bradbury Landing site was less than from the center of the rover's touchdown target after a journey. Mission goals include an investigation of the Martian climate and geology, assessment of whether the selected field site inside Gale has ever offered environmental conditions favorable for microbial life (including investigation of the role of water), and planetary habitability studies in preparation for human exploration. In December 2012, ''Curiosity'' two-year mission was extended indefinitely, and on August 5, 2017, NASA celebrated the fifth anniversary of the ''Curiosity'' rover landing.

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

Mars
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, only being larger than Mercury (planet), Mercury. In the English language, Mars is named for the Mars (mythology), Roman god of war. Mars is a terrestrial planet with a thin atmosphere (less than 1% that of Earth's), and has a crust primarily composed of elements similar to Earth's crust, as well as a core made of iron and nickel. Mars has surface features such as impact craters, valleys, dunes and polar ice caps. It has two small and irregularly shaped moons, Phobos (moon), Phobos and Deimos (moon), Deimos. Some of the most notable surface features on Mars include Olympus Mons, the largest volcano and List of tallest mountains in the Solar System, highest known mountain in the Solar System and Valles Marineris, one of the largest canyons in the Solar System. The North Polar Basin (Mars), Borealis basin in the Northern Hemisphere covers approximately 40% of the planet and may be a la ...

Terrestrial Analogue Sites
Terrestrial analogue sites (also called "space analogues" or terrestrial analog sites) are places on Earth with assumed past or present geological, environmental or biological conditions of a celestial body such as the Moon or Mars. Analogue sites are used in the frame of space exploration to either study geological or biological processes observed on other planets, or to prepare astronauts for surface extra-vehicular activity. Definition Analogue sites are places on Earth with assumed, past or present, geological, environmental or biological conditions of a celestial body. Analogue site studies are necessary because they help to understand geological processes (on Earth) which can be extrapolated to other Solar System bodies in order to interpret and validate the data received from orbiters or planetary rovers. Analogue sites are also important for optimizing scientific and technological needs and exploration strategies in robotic or crewed missions to the Moon or Mars. The def ...
