MESSENGER
''MESSENGER'' was a NASA robotic space probe that orbited the planet Mercury between 2011 and 2015, studying Mercury's chemical composition, geology, and magnetic field. The name is a backronym for "Mercury Surface, Space Environment, Geochemistry, and Ranging", and a reference to the messenger god Mercury from Roman mythology. ''MESSENGER'' was launched aboard a Delta II rocket in August 2004. Its path involved a complex series of flybys – the spacecraft flew by Earth once, Venus twice, and Mercury itself three times, allowing it to decelerate relative to Mercury using minimal fuel. During its first flyby of Mercury in January 2008, ''MESSENGER'' became the second mission, after Mariner 10 in 1975, to reach Mercury. ''MESSENGER'' entered orbit around Mercury on March 18, 2011, becoming the first spacecraft to do so. It successfully completed its primary mission in 2012. Following two mission extensions, the spacecraft used the last of its maneuvering propellant to deor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maria Helena Vieira Da Silva
Maria Helena Vieira da Silva (13 June 1908 – 6 March 1992) was a Portuguese abstract painter. She was considered a leading member of the European abstract expressionism movement known as Art Informel. Her works feature complex interiors and city views using lines that explore space and perspective. She also worked in tapestry and stained glass. Life Vieira da Silva was born in Lisbon, Portugal. At an early age, she traveled around the world because her affluent father was a diplomat. During this time, she came in contact with various avant-garde groups, such as the Italian Futurists and the Ballets Russes. At the age of eleven she had begun seriously studying drawing and painting at the ''Academia de Belas-Artes'' in Lisbon. In her teen years she studied painting with Emília dos Santos Braga in Lisbon and Fernand Léger, sculpture with Antoine Bourdelle, and engraving with Stanley William Hayter. Vieira da Silva also worked with Fauve artist Othon Friesz. In 1928 Vieira ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vieira is a Portuguese and Galician term which in Portuguese and Galician stands for the Great Pilgrim Mussel from the scallop family (Pectinidae). The term derives its use as a place and family name. History The use of the term can be traced, according to current knowledge, to the beginning of the 13th century in northwestern Portugal. The historical writing form of the term ''Vieira'' was ''Vyeyra''. It is assumed that the term as a name originated independently in different places (e.g. Vieira do Minho and Vieira de Leiria). As a surname, the term is first found in northwestern Portugal in the province of Minho in the era of Kings D. Afonso II and D. Sancho II of Portugal around 1220 A.D. The historically common spelling Vyeyra is still found at least until the end of the Middle Ages in the mid-16th century. The modern Portuguese alphabet basically does not recognise the letter Y alongside the K and W, only the 23 letters of the Latin alphabet A, B, C, D, E, F, G, H, I, J, ...

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 mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Astronomical Union
The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded in 1919 and is based in Paris, France. 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. It sponsors nine annual symposia and holds a triannual General Assembly that sets policy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The National Aeronautics and Space Administration (NASA ) is an independent agencies of the United States government, independent agency of the US federal government responsible for the civil List of government space agencies, space program, aeronautics research, and outer space, space research. NASA was National Aeronautics and Space Act, 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 program, 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), Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew Program, Commercial Crew ...

Mena (Mercurian Crater)
Mena is a crater in the Beethoven quadrangle on Mercury. Its name was adopted by the International Astronomical Union in 1976. Mena is named for the Spanish poet Juan de Mena, who lived from 1411 to 1456. Mena lies on the eastern rim of a larger unnamed crater, which is in turn within the much larger crater Vieira da Silva. Crater Type and Features Situated on the rim of an older, larger crater, Mena does not take on the typical bowl shape created by smaller impacts. Instead, Mena is classified as a complex crater with a peak located inside the bowl-shaped cavity. This peak is caused by a propagating shock wave In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance that moves faster than the local speed of sound in the medium. Like an ordinary wave, a shock wave carries energy and can propagate through a me ... that rebounds and converges at the crater's center, causing the target material to be uplifted.
