Artemis II Successful Splashdown: Historic Crewed Lunar Mission Completes
Summary: On the evening of April 10, US Eastern Time (morning of April 11, Beijing Time), NASA's Artemis II crew safely splashed down in the Pacific Ocean aboard the Orion spacecraft 'Integrity', marking the successful conclusion of the United States' first crewed lunar flyby mission in over 50 years. All four astronauts have been successfully recovered and are being transported to the USS John P. Murtha naval vessel for post-mission medical evaluations before returning to shore.

Mission Completes Successfully
At 9:56 PM EDT on April 10 (9:56 AM Beijing Time on April 11), the Artemis II crew - NASA astronauts Reid Wiseman, Victor Glover, Christina Koch and Canadian Space Agency astronaut Jeremy Hansen - were safely extracted from the Orion spacecraft and flown to the USS John P. Murtha naval vessel via US helicopters.
This marks the complete success of NASA's Artemis II mission. Not only was this the first crewed mission to the vicinity of the Moon since Apollo 17 in 1972, but it also represented the first crewed deep space flight using modern technology systems.
Splashdown Details
- Splashdown Time: 8:07 PM EDT on April 10 (8:07 AM Beijing Time on April 11)
- Splashdown Location: Pacific Ocean off the coast of San Diego, California
- Recovery Operations: Approximately one hour after splashdown, NASA and US military personnel approached the spacecraft in inflatable boats
The NASA recovery director directed team members from NASA and the U.S. military to approach the spacecraft in inflatable boats. Approximately one hour after splashdown, the crew was extracted from Orion and flown to the USS John P. Murtha naval vessel.
Crew Health Status
All four crew members are in good health and are currently undergoing post-mission medical evaluations in the medical bay of the USS John P. Murtha. They will subsequently return to shore to board a flight bound for NASA's Johnson Space Center.
NASA will hold a post-splashdown press conference at 10:35 PM EDT on April 10 from the agency's Johnson Space Center in Houston, with participants including:
- NASA Associate Administrator Amit Kshatriya
- Lori Glaze, acting associate administrator, Exploration Systems Development Mission Directorate
- Rick Henfling, entry flight director, Artemis II
- Howard Hu, manager, Orion Program
- Shawn Quinn, manager, Exploration Ground Systems Program
Scientific Achievements
During the 10-day mission, the Artemis II crew collected extensive scientific data:
- Captured over 175 GB of image data during the lunar flyby
- Successfully transmitted 20 GB of data via experimental laser communication payload in just 45 minutes
- Transmission speeds far exceeded traditional S-band telemetry systems
All lunar scientific data will be made public within 6 months of splashdown, providing valuable reference for future deep space exploration.
Technical Highlights
Laser Communication Breakthrough: The experimental laser communication payload aboard the Orion spacecraft demonstrated tremendous potential, proving the feasibility of future deep space communications.
Modern Deep Space System Validation: Artemis II validated the collaborative capability of the SLS rocket, Orion spacecraft, and ground support systems, laying the foundation for future Mars missions.
Historical Significance
The successful splashdown of Artemis II marks a crucial first step in the United States' return to the Moon program. This mission not only demonstrated the reliability of technical systems but also accumulated valuable experience for the upcoming Artemis III lunar landing mission.
