A half-century after American astronauts walked on the Moon, NASA and its international partners are taking the dream of Apollo a giant step further. In the coming years, the Artemis missions – named after Apollo's twin sister in Greek mythology – aim to bring astronauts back to the Moon and establish a lunar space station for scientific and commercial exploration. Follow the four members of the Artemis II crew as they embark on a perilous 10-day journey to orbit the Moon, venturing beyond Earth orbit for the first time since Apollo and farther into the Solar System than any humans have gone before. And get an inside look at the preparations needed to overcome the extreme engineering challenges of human-crewed spaceflight, all the way from launch to splashdown.
