Wind speeds on Mars are high enough to blow fleets of large spherical rovers that resemble tumbleweed across the Red Planet's surface, according to new wind-tunnel tests of small prototypes conducted by an international consortium of young scientists.
"We now have experimental validation that tumbleweed rovers could indeed operate and collect scientific data on Mars," James Kingsnorth of the Delft University of Technology in the Netherlands and head of science at Team Tumbleweed said in a statement.
