Unveiled: The Moon’s Hidden Grand Canyons Formed by Massive Cosmic Impact

Washington

The Grand Canyon in Arizona is an awe-inspiring natural wonder, a testament to the forces of nature over millions of years. However, new research has revealed two canyons on the moon, each comparable in size to the Grand Canyon, that were formed in an instant by an entirely different process.

A Cataclysmic Cosmic Collision

Asteroid or comet impact struck the lunar surface approximately 3.8 billion years ago, creating an area known as the Schrödinger impact basin. This event carved out two canyons near the moon’s south pole in a matter of less than 10 minutes, a revelation that challenges our understanding of lunar geology.

According to David Kring, a geologist from the Lunar and Planetary Institute in Houston, the impact released an energy equivalent to 130 times the current global inventory of nuclear weapons. Dr. Kring led the study published in Nature Communications, detailing the groundbreaking findings.

Forming the Canyons

Researchers mapped the canyons using data from NASA’s Lunar Reconnaissance Orbiter and computer modeling to simulate the flow and speed of flying debris. The ejected materials traveled at around 2,200 miles per hour, carving out Vallis Planck (174 miles long and 2.2 miles deep) and Vallis Schrödinger (168 miles long and 1.7 miles deep).

The collision occurred during a period of heavy bombardment by space rocks, possibly triggered by a change in the orbits of the outer planets Jupiter, Saturn, Uranus, and Neptune. The impactor measured about 15 miles in diameter, larger than the asteroid responsible for the extinction of dinosaurs 66 million years ago.

The Lunar Impact Process

The asteroid or comet struck the lunar surface, excavating a massive volume of rock. This debris was launched into space and descended in a violent cascade, creating smaller impact events that carved the canyons. Adjacent areas were covered in debris, preserving the lunar surface in a state untouched by geological processes like Earth’s plate tectonics.

This event marked one of the final massive impacts during the early solar system’s bombardment period, leaving lasting scars on the moon’s landscape.

Understanding the Moon’s Early History

The Schrödinger impact basin is situated near the Artemis mission’s exploration zone, offering a unique opportunity for lunar exploration. NASA plans to return astronauts to the moon for the first time since the Apollo landings of the 1970s.

Artemis missions could collect samples from this region, potentially providing insights into the moon’s earliest epochs. Scientists could also test hypotheses about the moon’s creation and early geological history, such as the impact hypothesis and the lunar magma ocean theory.

The Future of Lunar Exploration

The discovery of these lunar canyons underscores the untapped potential for scientific discovery on the moon’s surface. The preserved lunar landscape offers a rare, unaltered glimpse into the early solar system, invaluable to understanding our cosmic origins.

As the Artemis mission proceeds, these findings will play a crucial role in guiding exploration efforts, ensuring that future astronauts can collect the most informative samples possible. This represents a significant step toward unlocking the secrets of our celestial neighbor.

Conclusion

The recent discovery of the Schrödinger impact basin’s canyons offers a window into the moon’s violent past and its potential for future exploration. This research adds to our understanding of the moon’s geological history and highlights the importance of continued lunar missions in unlocking the mysteries of our solar system.
