NASA's Artemis II astronauts launched on a nine-and-a-half-day mission around the moon and back.

Four astronauts are in Earth orbit and will soon race toward the moon but first they'll test the craft while relatively close to home.

As of 9 a.m. ET on Friday, April 3, the Artemis II crew is almost 84,000 miles away from Earth, and hurtling through space at 4,417 mph towards the moon, according to NASA's Artemis II tracker.
