NASA is apparently pretty serious about building a base on the Moon, and the astronauts who just flew there say it is "absolutely doable."
Within two days of landing on Earth, the Artemis II astronauts were already back in spacesuits, working as if they had just landed in a gravity well and had ventured outside onto the lunar surface for a spacewalk.
"We were in surface spacewalk suits, doing surface geology tasks, and doing them well," said Christina Koch, a mission specialist on the Artemis II mission. "(We were) able to complete an entire battery of very challenging surface tasks."
