Moon’s Schrödinger Basin Reveals Ancient Secrets with Two Enormous Canyons
Table of Contents
Our Moon, a celestial neighbour that has long captivated humanity, continues to surprise scientists with its hidden features. Recent discoveries about two canyons branching from a major lunar impact have shed new light on the Moon’s turbulent past. The site in question is the Schrödinger basin near the Moon’s South Pole, formed when an asteroid or possibly even a leftover planetesimal slammed into the surface.
According to David Kring of the Lunar and Planetary Institute in Houston, TX, the impact is of vrey ancient origin. “Nearly four billion years ago,” he saeid, “an asteroid or comet flew over the lunar south pole, brushed by the mountain summits of Malapert and Mouton, and hit the lunar surface.The impact ejected high-energy streams of rock that carved two canyons that rival the size of Earth’s Grand Canyon.While the Grand Canyon took millions of years to form, the two grand canyons on the Moon were carved in less than 10 minutes.”
These two canyons—named Vallis Schrödinger and Vallis Planck—are meaningful clues to that turbulent time in the Moon’s past. They are impressive in scale, with Vallis Schrödinger being just under 300 kilometers long, 20 km wide, and 2.7 kilometers deep. Vallis Planck has two units: one is a deep canyon within the ejecta blanket of debris thrown out by the impact, and the other comprises a row of craters made as falling rocks were thrown out from the impact. The canyon part of Vallis Planck is about 280 kilometers deep, 27 km wide, and 3.5 km deep. The depth of both of these canyons surpasses the deep gorges of Earth’s Grand Canyon in Arizona.
Anatomy of an Impact and its aftermath
the impactor probably slammed into the surface at nearly 55,000 kilometers per hour. This crash produced the enormous 320-kilometer-diameter schrödinger impact basin. In the aftermath,the rocky debris scoured the deep canyons. Schrödinger formed in the outer margin of the South Pole-Aitken (SPA) basin, which is the largest and oldest impact basin on the Moon. The basin’s rim is about 300 km from the South Pole and within 125 km of the proposed exploration site for the Artemis mission.
The Schrödinger crater has a ~150-km diameter peak ring and the whole area is surrounded by a blanket of impact ejecta that splashed out in an irregular pattern up to 500 km away. The outermost crater ring resembles a circular mountain range and rises 1 to 2.5 km above the basin floor. It was produced by the collapse of a central uplift after the impact. After the impact, basaltic lava flows flooded the area. A large pyroclastic vent erupted more material onto the basin floor. That volcanic activity ended around 3.7 billion years ago.
Impact Anomalies
A careful analysis of the impact basin, the canyons, and the ejecta surrounding the site by Kring and a team of scientists at the Lunar Planetary Laboratory gives an idea of impact details. In a paper released about the site, the scientists discuss its features, plus some unusual finds. Such as,the canyon rays don’t converge at the basin’s centre as you might expect from typical impacts. They seem to come together in a different spot. That implies a point explosion impact.

Unraveling the secrets of Schrödinger Basin: A Deep Dive into the Moon’s Impact history
The Schrödinger Basin, a colossal impact crater on the Moon, has long been a subject of fascination for astronomers and space enthusiasts alike. Recent findings, as outlined in a extensive study, have shed new light on the basin’s formation and its implications for understanding the Moon’s history and the broader solar system.
The Impact That Shaped a Basin
The Schrödinger Basin, with its distinctive ejecta blanket and radial secondary crater rays, is a testament to a cataclysmic event that occurred billions of years ago. The location of the converging rays suggests that the incoming asteroid’s trajectory was approximately 33.5 degrees west of north. This evidence also points to a distributed impact, which could mean the impactor came in at a low angle. Alternatively, it’s possible that secondary ejecta from the impact also came in at low angles. The numerous secondary craters in the area support these possibilities.
Gareth Collins, a team member of the study, noted the similarities between the Schrödinger crater and the Chicxulub crater on Earth, which is believed to have caused the extinction of the dinosaurs. “The Schrödinger crater is similar in many regards to the dino-killing Chicxulub crater on Earth. By showing how Schrödinger’s km-deep canyons formed, this work has helped to how energetic the ejecta from these impacts can be,” Collins said.
future: Artemis Missions and Beyond
the upcoming Artemis missions by NASA present an exciting chance to explore the Schrödinger Basin further. The evidence from the ejecta blanket indicates an uneven distribution, particularly in the areas where the first missions are planned. This will allow astronauts and robotic probes to reach underlying samples of the Moon’s primordial crust without having to dig through rocks of a younger age.
The basin, being the second-youngest on the Moon, offers a unique chance to test the actual age of the impact. The rocks melted by the impact will provide valuable insights into the Moon’s geological history. The general understanding is that around 3.8 billion years ago, the Moon (and Earth) experienced a great many collisions during the Late Heavy Bombardment. This epoch,thought to have lasted up to 200 million years,scarred the surfaces of the rocky planets and the Moon,as well as asteroids.
Lunar rocks created consequently of lava flows during this time will open a window into their ages and mineralogy, especially compared to other, older rock formations. They should also improve our understanding of that period of solar system history,particularly the impacts on Earth that affected not just the surface but its life forms.
