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.
Molière is an impact crater on the planet Mercury, 139 kilometers in diameter. It is located south of the crater Rodin, southeast of the crater Abu Nuwas, and northeast of the crater Asvaghosa. The nearly circular rim of the crater is cut off into a flat edge on its southern and southwestern ends, and on its eastern side the rim is indented by a smaller crater. The crater is named for the 17th-century French dramatist and satirist Molière. The name was approved by the International Astronomical Union in 1976.
Kuiper is a moderate-size crater with a central peak cluster located at 11.35°S 31.23°W on Mercury. It is 62 kilometers in diameter and was named after Dutch-American astronomer Gerard Kuiper in 1976. It is one of only 2 Mercurian craters which are named not after artists, and one of very few cases when the same name is used for 3 craters. Gerard Kuiper, being a leader of American planetary science, died shortly before the first images of Mercurian surface were made.
Mozart is a crater on Mercury, named by the IAU in 1976 after Austrian composer Wolfgang Amadeus Mozart.
Apollodorus is an impact crater on Mercury. Its unusual appearance, with radiating dark troughs, led to a nickname of "the Spider" by scientists before its official name was decided. Apollodorus is located near the center of Pantheon Fossae, which is a system of radial grabens situated in the inner part of the Caloris basin. The floor, rim and walls of Apollodorus expose a low reflectance material (LRM) excavated during the impact from beneath the light volcanic plains, which cover the central part of the Caloris.
Xiao Zhao crater is small in comparison with many other craters on Mercury. However, Xiao Zhao's long bright rays make it a readily visible feature. The fresh, bright rays, which were created by material ejected outward during the impact event that formed the crater, indicate that Xiao Zhao is a relatively young crater on Mercury's surface.
Atget crater is distinctive on the planet Mercury's surface due to its dark color. Atget crater is located within Caloris basin, near Apollodorus crater and Pantheon Fossae. The dark color of the floor of Atget is in contrast to other craters within Caloris basin that exhibit bright materials on their floors, such as the craters Kertész and Sander. Other craters on Mercury, such as Bashō and Neruda, have halos of dark material but the dark material does not cover the crater floors.
Praxiteles is a crater on Mercury. It is one of 110 peak ring basins on Mercury.
Amaral is a crater on the planet Mercury. With its smooth floor, surrounding ejecta, and small secondary craters, it appears noticeably younger than the heavily cratered surface around it. Along with a smooth crater floor, Amaral also has a central peak. Bright material on this peak is of particular interest as it appears to have an unusual color. In color-enhanced images, the central peak of Amaral appears as a bright blue color in striking contrast to the otherwise orange tones of surface material nearby. The different color of the central peak likely indicates rocks with different chemical composition from those on the neighboring surface.
Calvino is a crater on Mercury. Its name was adopted by the IAU in 2016, after the Italian writer Italo Calvino.
Bartók is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) in 1979. Bartók is named for the Hungarian composer Béla Bartók, who lived from 1881 to 1945.
Bramante is a crater on Mercury. It has a diameter of 156 kilometers. Its name was adopted by the International Astronomical Union in 1976. Bramante is named for the Italian architect Donato Bramante, who lived from 1444 to 1514.
Darío is a crater on Mercury. It has a diameter of 151 kilometers. Its name was adopted by the International Astronomical Union (IAU) in 1976. Dario is named for the Nicaraguan poet Rubén Darío, who lived from 1867 to 1916.
Hitomaro is a crater on Mercury. It has a diameter of 105 kilometers. Its name was adopted by the International Astronomical Union (IAU) in 1976. Hitomaro is named for the Japanese poet Kakinomoto no Hitomaro, who lived from the 650s to roughly 709.
Lu Hsun is a crater on Mercury. It has a diameter of 98 kilometers. Its name was adopted by the International Astronomical Union (IAU) in 1976. Lu Hsun is named for the Chinese writer Lu Hsun, who lived from 1881 to 1936.
Nervo is a crater on Mercury. It has a diameter of 63 kilometers. Its name was adopted by the International Astronomical Union in 1979. Nervo is named for the Mexican poet Amado Nervo, who lived from 1870 to 1919.
Holst is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) on April 24, 2012.
Caravaggio is a large crater on Mercury. The crater was named after the Italian painter Caravaggio by the IAU in 2013.
Hollows are a landform on the planet Mercury, discovered during the MESSENGER mission that orbited the planet from 2011 to 2015.
Larrocha is an impact crater on Mercury. It has a diameter of 196 km (122 mi), and it is one of 110 peak ring basins on Mercury. It is located in the Victoria quadrangle at 43.29°N 69.83°W.
