NASA’s Artemis II prepares for splashdown on Earth

NASA's Artemis II crew is preparing for the critical splashdown phase of their mission, targeting a return to Earth in the Pacific Ocean on December 11, 2024, following a successful lunar flyby that tested the Orion spacecraft's systems for future crewed landings. The four astronauts—Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch, and Mission Specialist Jeremy Hansen—are aboard the uncrewed Orion capsule as it begins its journey back from the Moon, marking the final major test before the Artemis III mission aims to return humans to the lunar surface. The splashdown, planned off the coast of San Diego, California, represents the culmination of a roughly 10-day mission that saw Orion venture thousands of miles beyond the Moon. This re-entry will be one of the most demanding parts of the flight, as the capsule must withstand temperatures approaching 5,000 degrees Fahrenheit (2,760 degrees Celsius) while plunging through Earth's atmosphere at nearly 25,000 miles per hour (40,000 km/h). Recovery teams from NASA and the U.S. Navy are already prepositioned in the Pacific, ready to retrieve the capsule and its invaluable crew. This mission is a pivotal step in NASA's broader Artemis program, which seeks to establish a sustainable human presence on the Moon and ultimately prepare for missions to Mars. The data collected during re-entry and splashdown on Artemis II is crucial for validating the spacecraft's heat shield, parachute systems, and recovery operations with astronauts on board. A successful conclusion will clear the way for Artemis III, currently scheduled for no earlier than 2025, which is planned to land the first woman and the first person of color on the lunar surface.
