Bonestell is a crater in the Northern hemisphere in the Mare Acidalium quadrangle of Mars, located at 42.37° North and 30.57° West.[1] It is 42.4 km in diameter and was named after Chesley Bonestell, a famous American space artist (1888-1986), whose drawings inspired many young people to study sciences.[2]
Impact craters generally have a rim with ejecta around them. In contrast, volcanic craters usually do not have a rim or ejecta deposits. As craters get larger (greater than 10 km in diameter) they usually have a central peak.[3] The peak is caused by a rebound of the crater floor following the impact.[4] If one measures the diameter of a crater, the original depth can be estimated with various ratios. Because of this relationship, researchers have found that many Martian craters contain a great deal of material; much of it is believed to be ice deposited when the climate was different.[5] Sometimes craters expose layers that were buried. Rocks from deep underground are tossed onto the surface. Hence, craters can show us what lies deep under the surface.
