Rocket Sled Parachute Design Verification - The best video of the year

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.
