Before Jessica Watkins was an astronaut, she was a geologist. Now working on the International Space Station, Jessica and her fellow astronauts are preparing to explore the Moon and beyond.

Tools designed for Earth geologists may not work in the lower gravity and extreme temperatures of the Moon, and that’s before you bring in the bulky spacesuits! NASA Explorers come together at space school to train astronauts to conduct science on the Moon.
