NASA’s Artemis II crew began their return journey to Earth on April 7 after completing a historic lunar flyby a day earlier. The crew, traveling aboard the Orion spacecraft about 236,000 miles from Earth, exited the Moon’s gravitational influence and initiated return procedures. The mission includes a call with International Space Station astronauts, scientific debriefs, and a planned trajectory correction burn to refine their path home.

The Artemis II crew woke to music and a long journey ahead.

Less than 24 hours after looping around the Moon, four astronauts aboard NASA’s Orion spacecraft began the slow pivot back toward Earth. They started Flight Day 7 roughly 236,000 miles from home, still carrying the momentum of a mission that marked humanity’s first crewed lunar flyby since Apollo-era flights more than five decades ago.

The crew of National Aeronautics and Space Administration (NASA) astronauts Reid Wiseman, Victor Glover and Christina Koch, along with Canadian Space Agency (CSA) astronaut Jeremy Hansen, crossed a key threshold early in the day. At 1:23 p.m. Eastern Time, Orion exited the Moon’s sphere of influence, the region where lunar gravity dominates spacecraft motion.

That transition marked a turning point. From that moment, Earth’s gravity again became the primary force shaping Orion’s path.

A quiet shift. But a decisive one.

Artemis II crew ISS call with Expedition 74 astronauts

Even as the spacecraft moved farther from the Moon, the crew maintained contact with colleagues in orbit closer to Earth.

At 2:40 p.m., Artemis II astronauts connected with crew members aboard the International Space Station (ISS) for a scheduled 15-minute audio call. On the station were NASA astronauts Jessica Meir, Jack Hathaway and Chris Williams, along with European astronaut Sophie Adenot of the European Space Agency (ESA).

The exchange, broadcast via NASA’s official channels, offered a rare ship-to-ship moment between astronauts operating at vastly different distances from Earth.

Such interactions serve both technical and symbolic purposes. They allow crews to compare conditions, share observations, and reinforce coordination across missions that together define current human spaceflight.

Lunar flyby data and science debrief after close Moon pass

Attention quickly shifted from conversation to analysis.

At 3 p.m., the Artemis II crew joined science teams on the ground for a detailed debrief. The timing was deliberate. Mission planners wanted to capture observations while impressions from the lunar flyby remained fresh.

The April 6 flyby carried Orion around the far side of the Moon, a region not visible from Earth. During that pass, astronauts documented surface features, lighting conditions and spacecraft performance, data expected to support planning for future Artemis missions.

NASA has positioned Artemis II as a test flight. Its purpose extends beyond demonstration to refinement. Every observation feeds into subsequent missions, including planned crewed landings under the Artemis program.

Engineers and scientists are expected to analyze crew feedback alongside telemetry data in the coming weeks.

(April 6, 2026) – Captured by the Artemis II crew during their lunar flyby on April 6, 2026, this image shows the Moon fully eclipsing the Sun. From the crew’s perspective, the Moon appears large enough to completely block the Sun, creating nearly 54 minutes of totality and extending the view far beyond what is possible from Earth. The corona forms a glowing halo around the dark lunar disk, revealing details of the Sun’s outer atmosphere typically hidden by its brightness. Also visible are stars, typically too faint to see when imaging the Moon, but with the Moon in darkness stars are readily imaged. This unique vantage point provides both a striking visual and a valuable opportunity for astronauts to document and describe the corona during humanity’s return to deep space. The faint glow of the nearside of the Moon is visible in this image, having been illuminated by light reflected off the Earth. NASA

Orion return trajectory correction burn details and timing

The most critical maneuver of the day was scheduled for later.

At 9:03 p.m., Orion’s thrusters were set to ignite for the first of three planned return trajectory correction burns. These burns are designed to fine-tune the spacecraft’s path toward Earth, ensuring precise reentry conditions.

Christina Koch and Jeremy Hansen were assigned to monitor spacecraft systems and oversee procedures during the maneuver. Such burns require exact timing and calibration, as even small deviations at this distance can translate into large trajectory changes closer to Earth.

NASA officials have described the return phase as a series of incremental adjustments rather than a single decisive action. Each burn builds on the last, gradually aligning Orion with its targeted splashdown corridor.

Between scheduled tasks, the crew was given staggered off-duty periods.

The downtime serves operational needs as much as personal ones. Rest cycles help maintain cognitive performance, particularly as the mission enters phases requiring sustained attention and procedural accuracy.

NASA scheduled a mission status briefing later in the day to provide updates on spacecraft systems, crew health and trajectory progress.

The Artemis II mission, part of NASA’s broader Artemis program, aims to reestablish human presence beyond low Earth orbit. Unlike earlier missions confined to orbital paths around Earth, Artemis II pushes into deep space, testing systems required for sustained lunar exploration.

Flight Day 7 marked a transition from exploration to return.

The Moon receded behind them. Earth, still distant, became the destination again.

The path home had begun.
