NASA is going back to the moon. What to know about Artemis II

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.
