It’s humanity’s first flight to the moon since 1972. In a throwback to Apollo, NASA’s Artemis II mission will send four astronauts on a lunar fly-around. Three Americans and a Canadian will launch into orbit around Earth and then head for the moon. They’ll hurtle several thousand miles beyond the moon, hang a U-turn and then come straight back during the nearly 10-day mission. The Artemis launch will begin at Florida’s Kennedy Space Center where the Apollo moonshots did. The mission will end with a splashdown homecoming into the Pacific.
