For the first time in human history, a crew of astronauts has laid eyes on the Orientale basin, a massive, bullseye-shaped crater often referred to as the Moon’s “Grand Canyon.” As the Artemis II crew crossed the two-thirds mark of their ten-day lunar flyby, they reported sightings of lunar features that had previously been the sole domain of robotic imagers and orbiting cameras.
The milestone comes as the crew—commander Reid Wiseman, mission specialist Christina Koch, Victor Glover, and Canadian astronaut Jeremy Hansen—navigates the Orion spacecraft toward a record-breaking distance from Earth. According to NASA’s online dashboard, the crew closed out the fourth day of their mission nearly 322,000 kilometers from Earth and 132,000 kilometers from the lunar surface.
The sighting of the Orientale basin is more than a visual triumph; it represents a shift in how humans interact with the lunar landscape. Although the basin has been mapped extensively by probes, the perspective provided by the Artemis astronauts offers a visceral, human understanding of the Moon’s ancient geology.
The ‘Grand Canyon’ of the Moon
During a live question-and-answer session hosted by the Canadian Space Agency, astronaut Christina Koch shared the crew’s excitement over the basin. Speaking to children in Canada, Koch described the feature as “very distinctive,” noting that the crew felt privileged to be the first humans to see the crater in its entirety.
The basin’s unique appearance—a series of concentric rings created by a massive impact billions of years ago—makes it one of the most recognizable landmarks on the lunar surface. NASA confirmed that this mission marks the first time the entire basin has been viewed by human eyes, providing a scale and depth that automated photography cannot fully capture.
Beyond the Orientale basin, the crew has already begun exploring the “far side” of the Moon. Ms. Koch described the first view of the lunar far side as “absolutely spectacular.” John Honeycutt, manager of NASA’s Space Launch System (SLS) program, noted during a briefing that the astronauts are seeing features of the Moon that have remained hidden from human sight since the dawn of spaceflight.
A Novel Vantage Point: Artemis vs. Apollo
While the Apollo missions of the 1960s and 70s are the gold standard for lunar exploration, the Artemis II crew is experiencing the Moon from a fundamentally different perspective. The Apollo flights typically flew about 70 miles above the lunar surface during their orbits.
In contrast, the Artemis II crew will maintain a closest approach of just over 4,000 miles. While this may seem further, the distance allows the astronauts to view the Moon as a complete, circular disk. This vantage point is critical for analyzing the lunar poles—regions of high interest for future missions due to the presence of water ice—and observing the Moon’s global topography in a single frame.
To prepare for this, the crew underwent rigorous geology training. Their objective is to photograph and describe specific lunar features, including ancient lava flows and impact craters, which will help scientists refine the maps used for future landings.
Mission Comparison: Orbit and Observation
| Feature | Apollo Missions | Artemis II Mission |
|---|---|---|
| Closest Approach | ~70 miles | ~4,000 miles |
| Visual Scope | Localized surface detail | Full lunar disk & poles |
| Primary Tooling | Specialized film cameras | High-res sensors & smartphones |
| Core Objective | Lunar landing/sampling | Lunar flyby/system validation |
The Human Element in Deep Space
Despite the exacting precision required for the Artemis program, the mission has maintained a surprisingly grounded, human atmosphere. The crew has integrated modern technology and personal touches into their routine, including the use of smartphones—devices NASA recently approved for spaceflights—to document their journey.
The daily routine on board Orion blends high-stakes piloting with the mundane and the whimsical. NASA reported that the crew began their most recent workday with a meal of scrambled eggs and coffee, waking up to the sound of Chappell Roan’s pop hit “Pink Pony Club.”
For Commander Reid Wiseman, the emotional weight of the mission is balanced by connectivity with his family. Wiseman, a father of two, described the experience of speaking with his daughters from deep space as the “greatest moment” of his life. He characterized the mission’s goals as “Herculean,” noting that humanity has not attempted such a feat in over half a century.

This sense of wonder is shared by Canadian astronaut Jeremy Hansen, who recently remarked that the experience of floating in microgravity makes him “feel like a little kid.”
Next Steps: The Lunar Sphere of Influence
The mission is now approaching a critical gravitational transition. The crew is expected to enter the “lunar sphere of influence” overnight, the point at which the Moon’s gravitational pull becomes stronger than that of Earth. This transition is essential for the Orion spacecraft to successfully whip around the Moon and begin its journey back home.
If the flight path remains nominal, the crew is poised to set a new record for the farthest distance any human has ever traveled from Earth. This flyby serves as a vital precursor to the long-term goal of establishing a permanent lunar base, which NASA intends to use as a staging ground for the eventual exploration of Mars.
The crew has already completed a manual piloting demonstration and a comprehensive review of their flyby plan to ensure all priority surface features are photographed before they leave the lunar vicinity.
The next confirmed milestone will be the spacecraft’s closest approach to the Moon, where the crew will conduct their final high-resolution analysis of the lunar poles before initiating the return trajectory to Earth.
