A swarm of spherical rovers, blown by the wind like tumbleweeds, could enable large-scale and low-cost exploration of the Martian surface, according to results presented at the Joint Meeting of the Europlanet Science Congress and the Division for Planetary Sciences (EPSC-DPS) 2025.
Recent experiments in a state-of-the-art wind tunnel and field tests in a quarry demonstrate that the rovers could be set in motion and navigate over various terrains in conditions analogous to those found on Mars.
Tumbleweed rovers are lightweight, 5-meter-diameter spherical robots designed to harness the power of Martian winds for mobility...
