Mariner 10
''Mariner 10'' was an American Robotic spacecraft, robotic space probe launched by NASA on 3 November 1973, to fly by the planets Mercury (planet), Mercury and Venus. It was the first spacecraft to perform flybys of multiple planets. ''Mariner 10'' was launched approximately two years after ''Mariner 9'' and was the last spacecraft in the Mariner program. (Mariner 11 and Mariner 12 were allocated to the Voyager program and redesignated ''Voyager 1'' and ''Voyager 2''.) The mission objectives were to measure Mercury's environment, atmosphere, surface, and body characteristics and to make similar investigations of Venus. Secondary objectives were to perform experiments in the interplanetary medium and to obtain experience with a dual-planet gravity assist mission. ''Mariner 10''s science team was led by Bruce C. Murray at the Jet Propulsion Laboratory. Design and trajectory ''Mariner 10'' was the first spacecraft to make use of an interplanetary gravitational slingshot ...

March Crater MESSENGER WAC IGF To RGB
March is the third month of the year in both the Julian and Gregorian calendars. It is the second of seven months to have a length of 31 days. In the Northern Hemisphere, the meteorological beginning of spring occurs on the first day of March. The March equinox on the 20 or 21 marks the astronomical beginning of spring in the Northern Hemisphere and the beginning of autumn in the Southern Hemisphere, where September is the seasonal equivalent of the Northern Hemisphere's March. Origin The name of March comes from '' Martius'', the first month of the earliest Roman calendar. It was named after Mars, the Roman god of war, and an ancestor of the Roman people through his sons Romulus and Remus. His month ''Martius'' was the beginning of the season for warfare, and the festivals held in his honor during the month were mirrored by others in October, when the season for these activities came to a close. ''Martius'' remained the first month of the Roman calendar year perhaps as l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mercury (planet)
Mercury is the smallest planet in the Solar System and the closest to the Sun. Its orbit around the Sun takes 87.97 Earth days, the shortest of all the Sun's planets. It is named after the Roman god ' ( Mercury), god of commerce, messenger of the gods, and mediator between gods and mortals, corresponding to the Greek god Hermes (). Like Venus, Mercury orbits the Sun within Earth's orbit as an inferior planet, and its apparent distance from the Sun as viewed from Earth never exceeds 28°. This proximity to the Sun means the planet can only be seen near the western horizon after sunset or the eastern horizon before sunrise, usually in twilight. At this time, it may appear as a bright star-like object, but is more difficult to observe than Venus. From Earth, the planet telescopically displays the complete range of phases, similar to Venus and the Moon, which recurs over its synodic period of approximately 116 days. The synodic proximity of Mercury to Earth makes Mercury most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The IAU is composed of individual members, who include both professional astronomers and junior scientists, and national members, such as professional associations, national societies, or academic institutions. Individual members are organised into divisions, committees, and working groups centered on particular subdisciplines, subjects, or initiatives. As of 2018, the Union had over 13,700 individual members, spanning 90 countries, and 82 national members. Among the key activities of the IAU is serving as a forum for scientific conferences.

'towel', ''afecta'' > 'affects'. Vowel harmony differs greatly from dialect to dialect, while many varieties assimilate both to the height and the quality of the preceding stressed vowel (e.g. ''terra'' 'Earth, land' and ''dona'' 'woman'); in other varieties, it is just the height that assimilates, so that ''terra'' and ''dona'' can be pronounced with either () or with (), depending on the speaker. *** In a wider sense, vowel harmony can occur in further instances, due to different processes involving palatalisation, velarisarion and labialisation **In certain cases, the unstressed become silent when followed or preceded by a stressed vowel: ''quinze anys'' . **In cer ...

The Catalan-speaking territories are often called the or "Catalan Countries". The language evolved from Vulgar Latin in the Middle Ages around the eastern Pyrenees. Nineteenth-century Spain saw a Catalan literary revival, culminating in the early 1900s. Etymology and pronunciation The word ''Catalan'' is derived from the territorial name of Catalonia, itself of disputed etymology. The main theory suggests that (Latin ...

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 ...

Eric Burgess
Eric Burgess (1920 – March 2005) was an English freelance consultant, lecturer and journalist, who wrote about the Pioneer program of space missions since the first tests in 1957. He was the science correspondent of the ''Christian Science Monitor'' in the period of many of the planetary probe launches, and was often the senior science reporter present at many of those events. Burgess is credited with the original idea that the Pioneer probes should carry a message for extraterrestrial intelligences. He approached Carl Sagan about his idea, which eventually resulted in the Pioneer plaque. Burgess was a fellow of the Royal Astronomical Society and British Interplanetary Society, and an associate fellow of the American Institute of Aeronautics and Astronautics. Burgess and Arthur C. Clarke Sir Arthur Charles Clarke (16 December 191719 March 2008) was an English science-fiction writer, science writer, futurist, inventor, undersea explorer, and television series host. ...
