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
Nebraska lunar sample displays astronaut Harrison Schmitt on the moon in 1972. Once lunar basalt 70017 was brought back to earth from the moon, the basalt moon rock was cut up into small fragments of approximately 1 gram.
