In a historic moment for lunar exploration, astronauts aboard the Artemis II mission have captured the first-ever images of the Moon\u2019s dramatic Orientale Basin taken by human observers. The photographs, taken on April 5, 2026, reveal the enormous impact structure on the Moon\u2019s far western limb, marking a milestone in humanity\u2019s renewed return to deep-space exploration.\u00a0<\/p>

The images were shared by NASA on its social media platform X, highlighting the scientific significance of the sighting.\u00a0<\/p>

\u201cHistory in the making. In this new image from our @NASAArtemis II crew, you can see Orientale basin on the right edge of the lunar disk. This mission marks the first time the entire basin has been seen with human eyes,\u201d the agency wrote.\u00a0<\/p>

A rare view of a lunar giant\u00a0<\/strong><\/p>

The Orientale Basin, often referred as the \u201cGrand Canyon of the Moon,\u201d is one of the largest and best-preserved impact basins in the solar system. Spanning roughly 950 km, the immense structure sits near the Moon\u2019s western edge, making it difficult to observe fully from Earth.\u00a0<\/p>

While robotic spacecraft have previously imaged the region, the view captured during the Artemis II flyby marks the first time astronauts have directly seen and photographed the entire basin.\u00a0<\/p>

For scientists, the moment is more than symbolic \u2014 it provides a unique observational perspective that could help refine understanding of lunar geology and the violent impacts that shaped the early solar system.\u00a0<\/p>

Relic of the solar system\u2019s violent past\u00a0<\/strong><\/p>

The basin formed approximately 3.8 billion years ago, during the final phase of the period known as the Late Heavy Bombardment, when asteroids and comets frequently struck the inner planets.\u00a0<\/p>

Unlike simple craters, the Orientale Basin is a multi-ring impact structure, resembling a giant bullseye across the lunar surface. Scientists believe its concentric rings formed after a colossal asteroid \u2014 estimated to be about 40 miles (64 km) wide \u2014 slammed into the Moon.\u00a0<\/p>

Computer models suggest the impact blasted around 816,000 cubic miles (3.4 million cubic kilometres) of lunar material into space \u2014 roughly 135 times the combined volume of Earth\u2019s Great Lakes.\u00a0<\/p>

The force of the collision caused the Moon\u2019s crust to rebound violently. The original crater collapsed almost instantly, producing the distinctive rings seen today.\u00a0<\/p>

A cosmic tidal wave\u00a0<\/strong><\/p>

Researchers estimate that debris thrown into the sky during the impact surged upward as high as 100 kilometres above the lunar surface \u2014 more than 11 times the height of Mount Everest.\u00a0<\/p>

The ejected material then fell back in a massive cascade, generating deep faults that may have cut through the Moon\u2019s crust and reached its mantle. The lunar surface continued to oscillate like liquid for nearly two hours, gradually settling into the basin\u2019s outer rings.\u00a0<\/p>

The innermost ring is believed to have formed when a towering central peak \u2014 created immediately after the impact \u2014 collapsed under its own immense weight.\u00a0<\/p>

A window into lunar evolution\u00a0<\/strong><\/p>

Today, the basin\u2019s floor is believed to be covered with solidified impact melt, material that was once molten during the catastrophic collision. Scientists consider Orientale one of the most important natural laboratories for studying how large impact basins form and how planetary surfaces evolve.\u00a0<\/p>

Because the structure remains unusually well preserved, researchers say it offers a rare glimpse into processes that shaped not just the Moon, but rocky worlds across the solar system.\u00a0<\/p>

With the Artemis II astronauts now documenting the region directly, scientists hope the observations will guide future missions \u2014 including potential landing sites under NASA\u2019s broader Artemis programme.\u00a0<\/p> <\/div>
