Apollo 17 investigate the possibility of relatively new volcanic activity in the same area. Cernan, Evans, and Schmitt returned to Earth on December 19 after a 12-day mission. Apollo 17 is the most recent manned Moon landing and the most recent time humans travelled beyond low Earth orbit. It was also the first mission to have no one on board who had been a test pilot; X-15 test pilot Joe Engle lost the lunar module pilot assignment to Schmitt, a geologist. The mission broke several records: the longest moon landing, longest total extravehicular activities (moonwalks), largest lunar sample, and longest time in
North Carolina lunar sample displays sample display commemorative style plaque, measuring 10 by 14 inches, consists of one "moon rock" particle specimen that was cut from lunar basalt 70017 and a North Carolina state flag.
