Geological Chronicle
Mackin is a 0.48-kilometer crater in the Taurus-Littrow valley, located at selenographic coordinates 20.1043° N, 30.726° E in the Macrobius (LAC-43) quadrangle. It sits adjacent to the similarly sized crater Hess, bordered by Camelot to the north, Shorty and Lara to the northwest, Nansen to the west, and Emory to the northeast.
During the Apollo 17 mission in 1972, astronauts Eugene Cernan and Harrison Schmitt landed north of Mackin in the Taurus-Littrow valley. Although the crew did not visit the crater itself, the astronauts named the feature after geologist Joseph Hoover Mackin.
