Artemis II Astronauts Return to Earth After Historic Moon Mission

NASA’s Artemis II mission has successfully returned to Earth, marking the first time humans have traveled to the vicinity of the Moon in more than half a century. The crew splashed down in the Pacific Ocean off the coast of San Diego on April 10, 2026, at 5:07 p.m. PDT.

The mission served as a critical test flight for the Orion spacecraft and the Space Launch System (SLS) rocket, pushing human exploration capabilities further than any previous crewed flight. The four-person crew reached a maximum distance of 252,756 miles from Earth during their journey.

Crew and Mission Duration

The historic voyage was completed by a multinational team consisting of three NASA astronauts and one Canadian Space Agency (CSA) astronaut:

• Reid Wiseman, serving as commander
• Victor Glover, serving as pilot
• Christina Koch, mission specialist
• Jeremy Hansen, CSA mission specialist

The mission lasted nearly 10 days, with some reports specifying a nine-day voyage. The crew traveled around the Moon and back, demonstrating the viability of the systems required for deep-space human travel.

Technical Re-entry and Recovery

The return phase involved significant technical challenges as the Orion spacecraft, which the crew named Integrity, re-entered the Earth’s atmosphere at speeds exceeding 24,000 mph (38,600 km/h).

During this descent, the spacecraft’s heatshield was subjected to temperatures half as hot as those found on the surface of the Sun. This extreme thermal environment caused a six-minute communications blackout between the capsule and mission control in Houston.

Contact was restored once the spacecraft cleared the most intense phase of re-entry, with Commander Reid Wiseman confirming to Houston that Integrity here. We hear you loud and clear.

Following the blackout, the spacecraft deployed its red-and-white parachutes to slow the capsule for a precision splashdown in the Pacific Ocean. The crew was subsequently recovered by a waiting ship and began medical evaluations.

Strategic Implications for the Artemis Program

The successful return of the Artemis II crew clears the operational path for the subsequent stages of the Artemis program. The overarching goal of the initiative is to return humans to the lunar surface and eventually establish a permanent base on the Moon.

Artemis II demonstrated extraordinary skill, courage, and dedication as the crew pushed Orion, SLS (Space Launch System), and human exploration farther than ever before.

NASA Administrator Jared Isaacman

Administrator Isaacman also noted that the crew accepted significant risk to gain the knowledge necessary for future lunar missions. He attributed the success of the mission to the mandate and resources provided by President Donald Trump and partners in Congress, as well as the contributions of the NASA workforce and international partners.

The mission has also provided new imagery of the Moon, contributing to the scientific understanding of the lunar environment as NASA prepares for future landings.
