WATCH: Artemis II crew arrives at Kennedy Space Center

NASA's Artemis II crew has arrived at Kennedy Space Center ahead of a planned April 1 launch for a 10-day mission. The crew will conduct the second crewed test flight of NASA's lunar exploration program, following the uncrewed Artemis I mission in 2022. Artemis II is a critical stepping stone toward NASA's goal of returning humans to the Moon and eventually establishing a sustained lunar presence. The mission will test life support systems, navigation, and other spacecraft functions in deep space before the agency proceeds with Artemis III, which aims for an actual lunar landing. Former NASA astronaut Susan Kilrain and ABC News contributor Hakeem Oluseyi provided commentary on the crew's preparations.
