Awesome Video: Testing a Martian Parachute With a Rocket Sled

Video Caption: A prototype Mars parachute is pulled from the sky with a rocket sled. The test applies the correct aerodynamic force to a parachute that is too large to fit in any existing wind tunnel.

The successful test approach allows engineers to study issues and improve parachute design.
