Using an Earth Wind Tunnel to Test a Parachute Bound for Mars The Planetary Society

In May and June of this year, NASA will launch two Mars Exploration Rover (MER) spacecraft to the Red Planet. The process of getting these rovers ready for launch involves a complicated series of tests, trials and tribulations – all designed to insure a successful mission. One such test was completed on January 15, when engineers used the world’s largest wind tunnel and an explosive mortar charge to successfully test MER’s final flight-ready parachute design.
