Ride Shotgun With NASA Saucer As It Flies to Near Space
Carried as payload during the shakeout flight were two cutting-edge technologies scheduled to be tested next year aboard this same type of test vehicle. The Supersonic Inflatable Aerodynamic Decelerator (SIAD) is a large, doughnut-shaped air brake that deployed during the flight, helping slow the vehicle from 3.8 to 2 times the speed of sound. The second, the Supersonic Disksail Parachute, is the largest supersonic parachute ever flown. It has more than double the area of the parachute which was used for the Mars Science Laboratory (MSL) mission that carried the Curiosity rover to the surface of Mars.
