Landslides Beyond Earth
Mass movements reshape worlds across the solar system
This journey emerged from 20 new research articles across Astronomy & Space, Interdisciplinary and Physics.
This topic surfaced automatically because research activity is surging — up +122% versus its 12-week baseline, across multiple disciplines.
When we think of landslides, we usually picture rain-soaked hillsides collapsing on Earth. But recent discoveries reveal that massive landslides also sculpt the surfaces of other worlds—from the rust-red dunes of Mars to the icy plains of distant Pluto. Understanding these planetary mass movements helps us see how gravity, geology, and surface conditions shape landscapes throughout our solar system.
Recent rover missions and spacecraft observations are uncovering dramatic evidence of landslides on Mars and Pluto, some large enough to bury entire cities. These discoveries are transforming our understanding of how planetary surfaces evolve and revealing that the processes reshaping Earth also operate—often at stunning scales—on alien worlds with vastly different conditions.

Open questions
Science still doesn't fully know:
- What triggers massive landslides on Pluto's icy surface in the absence of liquid water or seismic activity?
- How do the metallic dune formations on Mars relate to ancient landslide processes in low-gravity environments?
- Whether landslide frequency and scale on other planets can inform predictions of catastrophic mass movements on Earth?
