Artemis II returning to Earth for splashdown to end historic moon mission

NASA's Artemis II crew is scheduled to return to Earth on December 11, 2024, concluding their historic lunar mission with a splashdown in the Pacific Ocean near California, marking the successful completion of humanity's first crewed journey to lunar orbit in over 50 years. The four astronauts—Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen—will complete their approximately 10-day mission by executing a high-speed atmospheric reentry in their Orion spacecraft, traveling at about 25,000 miles per hour before deploying parachutes for a controlled ocean landing. The return sequence represents one of the most critical phases of the mission, as the Orion capsule must withstand temperatures approaching 5,000 degrees Fahrenheit during atmospheric reentry. NASA recovery teams stationed aboard the USS John C. Stennis will be positioned in the Pacific to retrieve the crew and spacecraft immediately after splashdown. This recovery operation follows protocols established during the uncrewed Artemis I mission but marks the first time since 1972 that humans have returned from lunar distances. Artemis II serves as the crucial final test flight before NASA attempts to land astronauts on the lunar surface with Artemis III, currently planned for no earlier than 2025. The mission has validated Orion's life support systems, radiation protection, and communication capabilities during the journey that took the crew approximately 6,400 miles beyond the far side of the Moon—farther than any humans have traveled from Earth. Data collected during reentry and recovery will inform final preparations for subsequent Artemis missions aimed at establishing a sustainable human presence on the Moon and eventually sending astronauts to Mars.
