Artemis II Completes 10-Day Lunar Flyby, Returning Humans to Moon’s Vicinity After 50 Years

The Artemis II mission marked a major milestone in human spaceflight as it successfully completed a 10-day crewed lunar flyby from 01/04/2026 to 10/04/2026, returning astronauts to the vicinity of the Moon for the first time in more than five decades. Launched from NASA’s Kennedy Space Center in Florida, the mission tested critical systems aboard the Orion spacecraft and demonstrated capabilities required for future deep space exploration missions. The mission began on 01/04/2026 at 6:35 p.m. EDT with liftoff from Launch Complex 39B using NASA’s Space Launch System (SLS), the most powerful rocket developed by the agency. The Orion spacecraft, named Integrity, carried a four-member international crew: NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with Canadian Space Agency astronaut Jeremy Hansen. After reaching a high Earth orbit, the crew conducted initial systems checks before proceeding toward the Moon on a trajectory designed to test navigation, communication, and life-support systems in deep space. A key milestone occurred on 06/04/2026 as the spacecraft traveled around the far side of the Moon. During this phase, the Artemis II crew reached a maximum distance of 252,756 miles (406,771 kilometers) from Earth, setting a new record for the farthest humans have ever traveled. This surpassed the previous record of 248,655 miles set by the Apollo 13 crew in 1970. The trajectory allowed the spacecraft to pass beyond the Moon and return toward Earth, validating mission profiles planned for future lunar landings under the Artemis program. The mission concluded on 10/04/2026 with a successful splashdown in the Pacific Ocean off the coast of San Diego at 8:07 p.m. EDT (5:07 p.m. PDT). Recovery teams secured the Orion capsule shortly after landing, completing all primary mission objectives. The flight provided NASA and its international partners with critical data on spacecraft performance, crew operations, and deep space conditions, supporting preparations for subsequent missions, including planned lunar surface landings. ● Day 1 (01/04/2026): Launch from Kennedy Space Center; Orion enters high Earth orbit for initial systems checks. ● Day 2 (02/04/2026): Translunar injection burn sends Orion toward the Moon; systems monitoring continues. ● Day 3 (03/04/2026): Deep space transit; crew conducts onboard experiments and navigation checks. ● Day 4 (04/04/2026): Midcourse correction maneuvers; communication and life-support systems evaluated. ● Day 5 (05/04/2026): Approach phase to the Moon; trajectory adjustments and lunar imaging begin. ● Day 6 (06/04/2026): Flyby of the Moon’s far side; record distance of 252,756 miles from Earth reached. ● Day 7 (07/04/2026): Return trajectory initiated; spacecraft begins journey back to Earth. ● Day 8 (08/04/2026): Deep space return transit; continued system tests and crew observations. ● Day 9 (09/04/2026): Final approach to Earth; re-entry preparations and system checks. ● Day 10 (10/04/2026): Re-entry and splashdown in the Pacific Ocean; mission successfully concludes.
