Artemis II Mission: NASA Astronauts Break Distance Records During Lunar Flyby

NASA’s Artemis II mission achieved a historic milestone on April 6, 2026, as its crew traveled farther from Earth than any humans in history. The four-person crew, consisting of three Americans and one Canadian, surpassed the previous distance record held by the Apollo 13 crew since 1970.

The Orion spacecraft reached a maximum distance from Earth of 252,756 miles at 7:02:51 p.m. ET on April 6, 2026. This surpassed the Apollo 13 record of 248,655 miles. The mission serves as a critical test flight to prepare for future lunar landings.

Lunar Flyby and Far Side Observations

The crew conducted a lunar flyby that allowed them to view parts of the far side of the moon with the naked eye for the first time. The spacecraft’s closest approach to the lunar surface occurred at 7:00:46 p.m. ET on April 6, 2026, reaching a distance of 4,067 miles.

During the flyby, the crew observed the Orientale basin, a crater approximately 600 miles wide that straddles the near and far sides of the moon. While positioned behind the moon, the astronauts looked for flashes caused by meteoric impacts on the lunar far side.

The mission also featured a planned loss of signal as the moon blocked communications between the Orion capsule and Mission Control. This blackout began at 6:43 p.m. ET on April 6, 2026, and lasted approximately 40 minutes, with contact restored at 7:25 p.m. ET. During this window, the crew witnessed an earthset, where the Earth appears to set behind the lunar horizon.

Mission Logistics and Technical Challenges

The Artemis II mission lifted off from the Kennedy Space Center in Florida on April 1, 2026. On flight day 6, the crew awoke to a recorded message from the late Apollo 13 commander Jim Lovell, which had been recorded two months prior to Lovell’s death in August 2025.

The mission has faced some technical difficulties regarding the spacecraft’s onboard facilities. Entry flight director Rick Henfling stated that the toilet on Artemis II had malfunctioned following the April 1 liftoff. While the toilet can now be used as normal, its performance has been inconsistent, and astronauts reported a smell emanating from the bathroom area located in the floor of the capsule.

Crew and Command

The mission is commanded by NASA astronaut Reid Wiseman. The crew is utilizing the Orion spacecraft to execute the lunar flyby, which is described as a step toward returning humans to the lunar surface. The mission includes international cooperation, featuring one Canadian crew member alongside the three American astronauts.

The flight’s trajectory and the ability to maintain spacecraft systems during a long-duration trip beyond low Earth orbit are central to the mission’s goals. By breaking the Apollo 13 distance record and successfully navigating the far side of the moon, NASA is validating the technology required for future boot prints on the lunar surface.
