1 00:00:06,279 --> 00:00:11,939 High above the Eastern Shore of Virginia a rocket is hurtling through the atmosphere at nearly twice the speed of sound 2 00:00:12,790 --> 00:00:17,580 Attached is a three thousand pound payload that is designed to test a parachute for Mars 3 00:00:18,730 --> 00:00:25,680 Onboard a computer is calculating the altitude and speed to determine the precise time that it will signal to deploy the parachute 4 00:00:26,710 --> 00:00:29,130 These aren't the first tests of parachutes from ours 5 00:00:29,590 --> 00:00:36,270 50 years ago NASA began lofting parachutes to altitudes and speeds meant to simulate the conditions of Mars entry 6 00:00:36,550 --> 00:00:42,629 those early tests demonstrated the challenges of inflating lightweight materials in a 1500 mile an hour wind and 7 00:00:42,940 --> 00:00:46,500 Having them survive. Well enough to help enable a safe landing on the Red Planet 8 00:00:47,379 --> 00:00:49,829 Today as our missions become ever more daring 9 00:00:49,950 --> 00:00:57,419 We need new parachutes capable of surviving those strenuous environments and we need ways of testing them at loads higher than ever before 10 00:00:57,820 --> 00:00:59,820 To make those tests a reality 11 00:00:59,920 --> 00:01:07,439 Engineers at NASA's Jet Propulsion Laboratory worked with NASA's Wallops Flight Facility to develop a new test technique the advanced supersonic 12 00:01:07,630 --> 00:01:10,019 parachute inflation research experiments or 13 00:01:10,270 --> 00:01:17,159 aspire project uses a two-stage black Brant 9 sounding rocket to carry its payload to the conditions needed to stress the parachute the 14 00:01:17,830 --> 00:01:25,439 Rocket is launched out over the Atlantic Ocean and ascends to altitudes where the atmosphere of Earth mimics the atmosphere near the surface of Mars 15 00:01:26,049 --> 00:01:29,639 The third and final aspired test launched on September 7th 16 00:01:29,680 --> 00:01:33,029 The parachute was deployed at nearly twice the speed of sound in 17 00:01:33,189 --> 00:01:37,949 Less than half a second 200 pounds of nylon Kevlar and tech Nora go from a small 18 00:01:38,020 --> 00:01:44,369 Drum sized bag with the density of wood to an inflated parachute with the volume of a large house generating nearly 19 00:01:45,009 --> 00:01:46,869 70,000 pounds of drag 20 00:01:46,869 --> 00:01:54,479 Here in slow motion images you can see the rapid emergence of the parachute as it begins generating the drag crucial for deceleration at Mars 21 00:01:54,970 --> 00:02:00,269 These images give us amazing insights into the physics and early behaviors of a supersonic parachute 22 00:02:00,850 --> 00:02:08,489 Inflation the apparent ease of the unfurling and unfolding in the parachute belies the severity of the extreme environment in which this occurs 23 00:02:10,440 --> 00:02:16,039 Awaiting below were a recovery team who had to retrieve both the parachute and the payload and return them to shore 24 00:02:16,620 --> 00:02:20,840 The parachute was then meticulously rinsed and hung to dry before inspection 25 00:02:21,510 --> 00:02:29,209 Miles and miles of thread and over 3 million stitches are used to hold the parachute together and we will examine each stitch 26 00:02:30,000 --> 00:02:32,360 after three successful tests of aspire
