Mistral (crater)
Mistral is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) in 1976. Mistral is named for the Chilean poet Gabriela Mistral, who lived from 1889 to 1957. A large irregular depression and several smaller ones are present in the southeastern part of the crater floor. A similar depression is present in the crater Veronese which overlies the northwest rim of Mistral, and small ones are present in the unnamed crater to the southwest. The depressions are similar to those within Navoi, Lermontov, Scarlatti, and Praxiteles. The depressions resemble those associated with volcanic explosions.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Veronese (crater)

Gabriela Mistral
Lucila Godoy Alcayaga (; 7 April 1889 – 10 January 1957), known by her pseudonym Gabriela Mistral (), was a Chilean poet-diplomat, educator and humanist. In 1945 she became the first Latin American author to receive a Nobel Prize in Literature, "for her lyric poetry which, inspired by powerful emotions, has made her name a symbol of the idealistic aspirations of the entire Latin American world". Some central themes in her poems are nature, betrayal, love, a mother's love, sorrow and recovery, travel, and Latin American identity as formed from a mixture of Native American and European influences. Her portrait also appears on the 5,000 Chilean peso bank note. Early life Mistral was born in Vicuña, Chile, but was raised in the small Andean village of Montegrande, where she attended a primary school taught by her older sister, Emelina Molina. She respected her sister greatly, despite the many financial problems that Emelina brought her in later years. Her father, Juan ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Navoi (crater)
Navoi is a crater on Mercury. It contains uncommon reddish material that indicates a different rock composition from its surroundings. Navoi also appears to have an irregularly shaped depression in its center. Such depressions have been seen elsewhere on Mercury, including within Praxiteles crater, and may indicate past volcanic activity. Navoi was named after Uzbek poet Ali-Shir Nava'i 'Ali-Shir Nava'i (9 February 1441 – 3 January 1501), also known as Nizām-al-Din ʿAli-Shir Herawī ( Chagatai: نظام الدین علی شیر نوایی, fa, نظامالدین علیشیر نوایی) was a Timurid poet, writer ... in 2008.

Lermontov (crater)
Lermontov is an impact crater on the planet Mercury. The crater is named after Mikhail Yuryevich Lermontov, a 19th-century Russian poet. The name was approved by the International Astronomical Union in 1976. The crater floor is somewhat brighter than the exterior surface and is smooth with several irregularly shaped depressions. Such features, similar to those found on the floor of Praxiteles, may be evidence of past explosive volcanic activity on the crater floor. Lermontov appears reddish in enhanced-color views, suggesting that it has a different composition from the surrounding surface. To the north of Lermontov are Proust and Bek craters. To the south is Chaikovskij, and to the southwest is Giotto.

Scarlatti (crater)
Scarlatti is a pit-floored crater on Mercury, which was discovered in 1974 by the ''Mariner 10'' spacecraft. It has a prominent peak ring, and it is one of 110 peak ring basins on Mercury.Chapman, C. R., Baker, D. M. H., Barnouin, O. S., Fassett, C. I., Marchie, S., Merline, W. J., Ostrach, L. R., Prockter, L. M., and Strom, R. G., 2018. Impact Cratering of Mercury. In ''Mercury: The View After MESSENGER'' edited by Sean C. Solomon, Larry R. Nittler, and Brian J. Anderson. Cambridge Planetary Science. Chapter 9. The crater floor is covered by the smooth plains material. The crater displays an arcuate collapse feature (central pit) along the northeastern peak ring. The size of the pit, which was first noticed in ''MESSENGER'' images obtained in January 2008, is . Such a feature may have resulted from collapse of a magma chamber underlying the central peak ring complex of the crater. The collapse feature is an analog of Earth's volcanic calderas. Scarlatti is thought to have the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Praxiteles (crater)
Praxiteles is a crater on Mercury. It is one of 110 peak ring basins on Mercury. ''MESSENGER''s high-resolution images obtained during the mission's second Mercury flyby have revealed a number of irregularly shaped depressions on the floor of Praxiteles crater, making it a pit-floor crater. The colors near these depressions in WAC images are similar to those near volcanoes discovered during the mission's first Mercury flyby along the inner edge of the Caloris basin. The similar colors and the association with the irregular depressions (possible volcanic vents) are suggestive of past volcanic activity on the floor of Praxiteles. The light coloration associated with the peak ring is now known as Orm Facula. Praxiteles crater, first observed by ''Mariner 10'', was named in 1979 by the IAU after the ancient Greek sculptor Praxiteles Praxiteles (; el, Πραξιτέλης) of Athens, the son of Cephisodotus the Elder, was the most renowned of the Attica sculptors of the 4 ...
