Team Tumbleweed is a student team building a wind powered Mars rover. The team's prototype can take advantage of the up to 360km/h winds which blow on the martian surface to gather data quickly and cover long distances without using on board propulsion. Once the team has grown enough and has created over 100 working prototypes, they want to transition to being a company and eventually launch their rovers onto Mars around the year 2029.
