Orion spacecraft achieves historic lunar flyby milestone on Artemis II mission
The Orion spacecraft, named Integrity, reached a groundbreaking milestone on Flight Day 6 of the Artemis II mission, successfully passing behind the Moon and temporarily losing communication with Earth for approximately 40 minutes. During this period, the crew of astronauts—Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen—were treated to breathtaking views of the lunar surface, observing features never before seen by human eyes. This achievement marked a historic moment, as the crew broke this record for the farthest distance humans have traveled from our planet.
The Artemis II mission, which launched on April 1, 2026, from Kennedy Space Center, is the first crewed mission under the Artemis program. The blackout in communications occurred as the Moon obstructed signals to Earth’s Deep Space Network, while the spacecraft was at its maximum distance from Earth, eclipsing the previous record set by Apollo 13 in 1970. Prior to this closest approach, Orion had traveled approximately 400,000 kilometers (about 248,500 miles) following its Trans-Lunar Injection burn.
Although the mission encountered some minor setbacks, such as plumbing issues in the spacecraft’s toilet system caused by a suspected clog, Mission Control managed to address the situation by adjusting the spacecraft’s orientation to expose the vent to sunlight, successfully thawing the blockage. As a temporary measure, the crew used Collapsible Contingency Urinals, sealable containers designed to handle urine, until the system returned to functionality.
On Flight Day 3, the crew captured a fun selfie by floating to the windows of Orion, which allowed them to gaze out as the Moon grew ever larger in their view. This unique trajectory offered the crew the ability to observe a wide array of lunar features, documenting their journey with photographs that spanned the Moon from pole to pole. They accessed the Moon’s gravitational influence on Flight Day 5, which shifted their trajectory toward the lunar surface.
The crew’s lunar flyby took place on April 6, when they prepared their windows for an unforgettable lunar sightseeing experience. They captured detailed images and made observations of the Moon’s far side and illuminated regions. The day also included a special moment as they listened to a heartfelt message from the late astronaut Jim Lovell, who was part of Apollo 8.
A fascinating twist of fate accompanied their journey; the crew observed a solar eclipse from their unique vantage point between the Moon and the Sun, right after clearing the lunar far side. This remarkable sight presented them the opportunity to study how solar winds affect lunar dust and its dynamic behavior on the airless surface, yielding valuable insights unlike any previously collected.
In a gesture commemorating their mission, the astronauts expressed interest in renaming lunar features to honor the Orion spacecraft, specifically proposing to name a feature after Commander Wiseman’s late wife, Carroll.
As Orion embarks on its return journey to Earth, the team has three planned trajectory correction burns at their disposal should they be necessary. Though bandwidth limitations hindered live broadcasts of the breathtaking views the crew described, they managed to capture stunning footage that will be transmitted to Earth in due time. Excitingly, a highlight of the mission will be a planned communication with the International Space Station, marking one of the first ship-to-ship conversations since the Apollo missions, now made possible by a sustained human presence in low Earth orbit.
With an expected total mission duration of approximately nine days and one hour, the Orion spacecraft is scheduled to separate from its service module and perform a high-speed atmospheric reentry, culminating in a splashdown in the ocean, where a U.S. Navy ship will recover the astronauts shortly thereafter.
