With the Red Planet becoming more interesting for both government space agencies as well as private companies, we decided it was time to revolutionize the way we explore Mars. Born from the winning entry for the Odysseus Space Contest in 2017, the Tumbleweed Mars rover leaves behind the traditional approach for rovers. Instead, the spherical rover is designed for the fast exploration of large areas, making use of the strong Martian winds. Modularity, the use of off-the-shelf components, and the production of more than 100 wind-driven rovers allow a significant decrease in costs – making Mars accessible for research institutions, companies, universities, or any organization willing to work with us to integrate their payload on a Tumbleweed.
