J-Missions. The so-called J-Missions of the Apollo program, which spent an extended period of three days on the lunar surface, with extensive scientific explorations, aided by the Lunar Rover. They were an incredible success, with tons of lunar material collected from sites spread over tens of kilometers on Hadley Apennine, Descartes, and Taurus Liitrow, thanks to the crews of Apollo 15, Apollo 16, and Apollo 17, respectively.
