NASA's Artemis II crew enters quarantine ahead of April 1 launch window

NASA's Artemis II four-person crew entered quarantine at Kennedy Space Center as the April 1 launch window opened for a 10-day lunar flyby. The flight will be the first crewed lunar voyage since the Apollo era, carrying astronauts around the Moon and validating Orion and SLS systems. Astronaut Christina Koch said the journey is starting to feel real as the team finalizes training and spacecraft checks. Success would advance Artemis plans for a sustained human presence on the Moon and reduce risk for future lunar landings.
