Researchers have identified six significant landslides on Pluto through a reanalysis of high-resolution imagery captured by NASA's New Horizons spacecraft. These geological features, located near the Sputnik Planitia region, provide critical insights into the dwarf planet's surface dynamics and material properties. The discovery confirms that Pluto, despite its icy composition, possesses the necessary environmental conditions to support mass movement events similar to those observed on terrestrial planets and other solar system bodies. The scientific team, led by physicist Maria Teresa Brunetti, emphasizes that these landslides play a fundamental role in shaping Pluto's landscape. By analyzing the morphology of these features, researchers have determined that the material involved experiences lower friction than comparable landslides on Earth, allowing them to travel over longer distances. This finding serves as a key indicator of the physical characteristics of the surface material on this distant world. The study, published in the journal Icarus on June 13, 2026, highlights that these landslides are situated along the steep inner rims of impact craters. With the largest feature spanning approximately 130 square kilometers, these events are comparable in scale to major terrestrial landslides. This research underscores the importance of re-examining existing planetary data to uncover previously overlooked geological phenomena. These findings offer a new framework for understanding planetary geology in the outer solar system. Future exploration and continued analysis of New Horizons data are expected to reveal more such features, further refining our knowledge of Pluto's evolution and its active surface processes.
