NASA's Artemis II mission is set to send four astronauts on a ten-day journey around the moon, marking the first time humans have left Earth's orbit in over half a century. The crew, consisting of Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen, will launch aboard the Space Launch System from Florida and travel over 620,000 miles in the Orion spacecraft. While they will not land on the moon, the mission will take them farther from Earth than any previous human travelers, performing a close lunar flyby before returning home. The mission aims to test deep-space systems with a human crew, paving the way for future lunar landings. Life aboard Orion will be challenging, with the astronauts living in tight quarters, exercising daily to prevent muscle loss, and using specially designed equipment for sleeping and hygiene.
