NASA’s Artemis II mission, which launched on April 1, 2026, has successfully carried four astronauts on a 10-day lunar flyby, marking the first crewed mission beyond low Earth orbit since Apollo 17 in December 1972.
The crew—consisting of Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen—traveled aboard the Orion spacecraft, named Integrity
by the crew, launched by the Space Launch System (SLS) rocket from Kennedy Space Center’s LC-39B.
The mission served as a critical test flight to demonstrate deep space capabilities and sustain crew members during a journey around the Moon, paving the way for future human landings on the lunar surface.
Mission Milestones and Records
Artemis II achieved several historic milestones during its flight. The mission took the crew further from Earth than any human has previously traveled in history as they orbited around the far side of the Moon.
The mission also established new precedents for representation in space exploration. Christina Koch became the first woman to circle the Moon, and Victor Glover became the first Black person to make the journey.
According to NASA, the 10-day mission was designed to test deep space systems and the Orion spacecraft’s ability to sustain astronauts before they return safely to Earth.
Flight Operations and Timeline
Following the launch on April 1, 2026, the spacecraft departed Earth orbit on April 2, 2026. During the mission, the crew conducted various key tests and operations, including the first return correction burn, which was completed on Flight Day 7.
By Flight Day 8, the crew was conducting essential tests required for their return to Earth. During the journey, the astronauts observed the far side of the Moon, Venus, and a solar eclipse.
The Orion spacecraft, developed by Lockheed Martin with the European Service Module (ESM) manufactured by Airbus, was designed to carry and sustain the crew throughout the mission. The spacecraft’s total launch mass was 78,000 pounds, with a planned landing mass of 20,500 pounds.
Technical Specifications and Recovery
The mission utilized the SLS, NASA’s new heavy-lift rocket, to propel the Orion capsule. The full launch stack reached a height of 322 feet, while the Orion and ESM combined measured 26 feet.
The spacecraft’s orbital parameters included a perigee altitude of 119 miles and an apogee altitude of 43,604 miles. The planned distance traveled for the mission was approximately 695,081 miles.
The mission’s conclusion involved a planned splashdown in the Pacific Ocean. The recovery operation was slated to be conducted by the USS John P. Murtha, with a landing date set for April 10, 2026, at 5:21 p.m. PDT (April 11, 2026, 00:21 UTC).
Path to Future Lunar Landings
Artemis II builds upon the success of the uncrewed Artemis I mission from 2022. It’s part of a broader program aimed at establishing a long-term human presence on the Moon and eventually sending crews to Mars.
The data and capabilities demonstrated during this flyby are intended to support subsequent missions. Specifically, the program aims to return humans to the lunar surface on board Artemis IV, which is scheduled for launch in 2028.
The mission also highlighted the roles of ground support and leadership, including the use of twin NASA control rooms to ensure safety and success.
