The American Apollo 15 mission, the first of the J-series missions that featured both increased scientific capability and the use of the Lunar Roving Vehicle, landed in an area of the Hadley-Apennine region to the west of the Apennine Front situated between the mountains Mons Hadley and Mons Hadley Delta to the northeast and south, respectively. This landing site was selected with the objectives of exploring the Apennine Front, Hadley Rille, and other geologic features in the area.
