The Most Complex Orion Parachute Test, Yet

The most recent test of the Orion spacecraft's parachute system was shown during a NASA Google+ Hangout. An Orion test article was pushed out of a C-17 aircraft 35,000 feet above the Army's Yuma Proving Ground in Arizona. Of the 17 parachute drops planned for the developmental test series, this is the 14th and most complex. Only two previous tests have been conducted from such a high altitude, and this one upped the ante further by waiting through 10 seconds of freefall before Orion's parachutes were deployed, to allow the vehicle to build up more speed and aerodynamic pressure before the first of the parachutes was released, to put the maximum amount of stress on them.
