NASA has successfully completed the Artemis II mission, marking the first crewed lunar flyby in five decades. The mission, which launched on April 1, 2026, and concluded with a splashdown on April 10, 2026, served as a critical test of deep space systems to prepare for future human landings on the Moon and eventual missions to Mars.
The crew traveled aboard the Orion spacecraft, named Integrity, which was launched by the Space Launch System (SLS)—NASA’s heavy-lift rocket designed to provide superior payload mass and departure energy. During the 9-day, 1-hour, and 32-minute journey, the crew reached their closest approach to the Moon, known as pericynthion, on April 6, 2026. At this point, the spacecraft flew within 6,545 kilometers (approximately 4,067 statute miles) of the lunar surface, utilizing the Moon’s gravity to bend their trajectory back toward Earth.
This milestone demonstrates the viability of the Orion spacecraft as an exploration vehicle capable of sustaining astronauts in deep space. The mission’s success highlights the continued evolution of human spaceflight capabilities and the technical precision required for long-duration lunar trajectories.
Following their return to Houston and reunion with their families, the astronauts shared their initial reflections. In early interviews, the pilot noted the magnitude of the experience, stating, “I still haven’t processed what we did.” Other crew members emphasized a renewed perspective on Earth, describing the planet as our “lifeboat” and calling for greater unity among humanity.
The mission included rigorous science observations, with a detailed observation plan uploaded to the spacecraft on April 5, 2026. This allowed the crew to view the entire disk of the Moon throughout the flyby and venture around its far side. The successful execution of these maneuvers paves the way for future lunar surface missions.
