last man, First Scientist on Moon — Kevin Fong talks to one of the last two men on the moon, forty years after the final Apollo 17 mission launched on 7th December 1972. As an Apollo astronaut, Harrison Schmitt was special. He was the only scientist ever to visit the lunar surface. The field work Dr Schmitt did among the craters, and the rocks he and his fellow astronauts brought back, transformed our knowledge of the Moon and the Earth. Harrison Schmitt also shares the human experience of running around another planet and explains why he thinks we should go back, and beyond.
