Lermontov (crater)
Lermontov is an impact crater on the planet Mercury (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 (crater), 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 (crater), Proust and Bek (crater), Bek craters. To the south is Chaikovskij (crater), Chaikovskij, and to the southwest is Giotto (crater), Giotto.

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 wide angle camera (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 The International Astronomical Union (IAU; , UAI) is an international non-governmental organization (INGO) with the objective of advancing astronomy in all aspects, ...

Hollows (Mercury)
Hollows are a landform on the planet Mercury, discovered during the ''MESSENGER'' mission that orbited the planet from 2011 to 2015. Hollows are typically clusters of rimless depressions with flat floors and haloes of bright (high albedo) material surrounding them. Hollows are thought to form by loss of volatiles from the surface by sublimation, caused by the intense solar radiation on the airless planet. They are some of the youngest features on Mercury. Hollows were first observed as bright areas within craters imaged by the Mariner 10 spacecraft in 1974, but the images were not of sufficient resolution to discern any detail. These craters include Balzac, Tyagaraja, Theophanes, Zeami, and Hopper.Dzurisin, D., 1977. Mercurian bright patches: Evidence for physio-chemical alteration of surface material?

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 mission to use a gravity assist from one planet (in this case, Venus) t ...
