The first humans to journey toward the Moon in more than half a century have safely returned to Earth, marking a major milestone for NASA’s ambitious Artemis program. The four-member crew of the Artemis II test flight splashed down in the Pacific Ocean off the coast of California at 5:07 p.m. PDT on Friday, concluding a nearly 10-day deep-space mission. The crew—NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian Space Agency astronaut Jeremy Hansen—traveled farther from Earth than any humans in history. At their most distant point, they reached 252,756 miles (406,000 kilometers) from Earth, surpassing the record set during Apollo 13.

After reentry, recovery teams from NASA and the U.S. military retrieved the Orion spacecraft and assisted the astronauts before transporting them by helicopter to the USS John P. Murtha for initial medical evaluations. The crew is scheduled to return to NASA’s Johnson Space Center in Houston the following day.
Launched on April 1 from Kennedy Space Center in Florida, Artemis II marked the first crewed flight of NASA’s powerful Space Launch System rocket and Orion spacecraft. Generating 8.8 million pounds of thrust at liftoff, the rocket carried the astronauts smoothly into orbit before sending them on a trajectory toward the Moon.
Within the first day, the crew conducted critical system checks on their spacecraft—named Integrity—ensuring all components functioned properly before continuing their journey. The mission also deployed four CubeSats from international partners into Earth orbit.
On the second day, Orion’s engine fired to send the spacecraft on a precise lunar trajectory, bringing the astronauts within 4,067 miles (6,545 kilometers) of the Moon’s surface during a dramatic flyby.
Over the course of the mission, the crew traveled a total distance of 694,481 miles, testing every major system required for future lunar exploration.
Artemis II served as a critical proving ground for technologies and procedures that will be used in upcoming missions. For the first time, astronauts evaluated Orion’s life support systems in deep space, confirming the spacecraft can sustain human life far beyond Earth orbit.
Crew members also manually piloted Orion during key phases of the mission, collecting data that will help guide future docking operations with lunar landers. They tested emergency protocols, exercise routines, and advanced spacesuits designed for long-duration missions.
Scientific research was another cornerstone of the mission. Experiments such as the AVATAR study examined how human tissue responds to microgravity and deep-space radiation, providing essential insights for future missions to the Moon and Mars.
During their April 6 lunar flyby, the astronauts captured more than 7,000 images of the Moon and surrounding space. These included detailed views of craters, ancient lava plains, and dramatic lighting conditions along the lunar terminator—the boundary between day and night.
The crew also documented Earthrise and Earthset from lunar orbit, observed meteoroid impacts on the Moon’s far side, and captured a rare solar eclipse from Orion’s perspective. These observations will help scientists better understand the lunar surface and identify potential landing sites for future missions.
Looking Ahead to Artemis III
With Artemis II successfully completed, NASA is now turning its focus to the next phase of lunar exploration: Artemis III. Scheduled for the coming years, Artemis III aims to return astronauts to the lunar surface for the first time since the Apollo era and begin construction of a sustained human presence near the Moon’s south pole.
NASA officials emphasized that Artemis II demonstrated not only the reliability of the spacecraft and rocket but also the strength of international collaboration, involving contributions from teams across 14 countries.
The mission is seen as a crucial step toward establishing a long-term human presence on the Moon, unlocking scientific discoveries, and laying the groundwork for future crewed missions to Mars.
