The tumbleweed is a large wind blown ball that we are considering for a mission to Mars. As shown in preliminary tests in California's Mojave Desert, the ball may possibly be used for landing, replacing both the parachute and airbag. It could carry a payload in the center of the ball by means of a series of tension cord bands. This 1.5 meter ball is being blown by a gentle breeze and rolls with a preferred horizontal axis. When the ball encounters rougher terrain, it gently bounces over smaller obstacles. The actual ball we are considering for Mars would be about 6 meters or 20 feet in diameter, and it could be stopped or slowed by partially deflating.
