* Collected lunar samples: He was primarily responsible for gathering rock and soil samples for scientific analysis back on Earth. These samples have provided a wealth of information about the Moon's formation, composition, and geological history.
* Explored the lunar surface: Schmitt and his crewmate, Eugene Cernan, drove the lunar rover for over 22 miles, exploring a variety of geological formations. They visited the Taurus-Littrow valley, which was chosen for its diverse landscape and potential to reveal information about the Moon's past.
* Performed scientific experiments: Schmitt and Cernan conducted experiments to analyze the lunar atmosphere, measure the Moon's magnetic field, and study the effects of the lunar environment on materials.
* Took iconic photographs: Schmitt's photographs of the lunar landscape are some of the most striking images ever taken of the Moon.
Schmitt's contributions were crucial to the success of Apollo 17. His geological expertise helped the crew to collect the most diverse and scientifically valuable set of lunar samples ever obtained. He also played a key role in making important scientific discoveries about the Moon's history and evolution.
