NASA's Artemis II astronauts have begun their journey to the Moon after a successful launch. The crew, consisting of Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen, is on a 'free-return' trajectory. They expressed excitement about seeing Earth from space and have made history as the first Black person, woman, and non-US citizen to launch to the Moon. Minor issues were encountered, but the crew is ready for the mission, which aims to establish a permanent lunar base by 2028.
