jsc2025e034457 (March 18, 2025) -- The official Artemis II mission crew patch. The Artemis II test flight begins when a mighty team launches the first crew of the Artemis generation. This patch designates the mission as “AII,” signifying not only the second major flight of the Artemis campaign, but also an endeavor of discovery that seeks to explore for all and by all. Framed in Apollo 8’s famous Earthrise photo, the scene of the Earth and the Moon represents the dual nature of human spaceflight, both equally compelling: The Moon represents our exploration destination, focused on discovery of the unknown. The Earth represents home, focused on the perspective we gain when we look back at our shared planet and learn what it is to be uniquely human. The orbit around Earth highlights the ongoing exploration missions that have enabled Artemis to set sights on a long-term presence on the Moon and soon, Mars. Credit: NASA

Teams from NASA, the Department of Defense Human Space Flight Support and SpaceX conduct a joint medical triage and medical evacuation (medevac) training exercise at NASA’s Kennedy Space Center in Florida. It was the second of two emergency medical services simulations performed before commercial crew flight tests, which are scheduled for 2019. As NASA’s Commercial Crew Program prepares to begin launching astronauts once again from American soil, teams are sharpening their launch day operations procedures, including responses during the unlikely event of an emergency.
