WEBVTT FILE 1 00:00:16.890 --> 00:00:27.790 welcome to NASA's spacecraft chamber of 2 00:00:19.990 --> 00:00:29.168 horrors here spacecraft and components 3 00:00:27.790 --> 00:00:31.270 suffer through a grueling battery of 4 00:00:29.169 --> 00:00:32.800 tests all in an effort to see if they 5 00:00:31.270 --> 00:00:34.570 are truly capable of performing their 6 00:00:32.800 --> 00:00:41.680 mission and surviving the rigors of 7 00:00:34.570 --> 00:00:43.540 spaceflight as this centrifuge whips 8 00:00:41.680 --> 00:00:45.970 them around they experience the kind of 9 00:00:43.540 --> 00:00:49.200 g-forces or gravitational forces that 10 00:00:45.970 --> 00:00:49.199 they can expect to see on launch 11 00:00:56.829 --> 00:01:01.600 now this interview is not for human use 12 00:00:59.020 --> 00:01:04.809 it can go up to 30 G's which is way more 13 00:01:01.600 --> 00:01:06.760 than a human being can stand they get 14 00:01:04.809 --> 00:01:10.408 shaken on any number of vibration tables 15 00:01:06.760 --> 00:01:10.409 to simulate the vibrations during launch 16 00:01:10.590 --> 00:01:17.220 there's no sound in space but the ride 17 00:01:13.540 --> 00:01:17.220 up can be noisy enough to break things 18 00:01:17.970 --> 00:01:22.658 inside this acoustics chamber the 19 00:01:20.770 --> 00:01:23.770 instruments are blasted with noise in 20 00:01:22.659 --> 00:01:27.330 order to make sure they'll be able to 21 00:01:23.770 --> 00:01:27.330 survive the rocket trip to space 22 00:01:42.560 --> 00:01:48.870 some like the new slick carrier come to 23 00:01:45.900 --> 00:01:52.830 this static load test facility some call 24 00:01:48.870 --> 00:01:54.570 it the rack inside this frame hydraulic 25 00:01:52.830 --> 00:01:56.399 actuators operated by a team of 26 00:01:54.570 --> 00:01:58.830 engineers push and pull the new 27 00:01:56.400 --> 00:02:00.540 composite payload carrier testing its 28 00:01:58.830 --> 00:02:05.009 ability to withstand the stresses of 29 00:02:00.540 --> 00:02:06.930 launch and re-entry based on the results 30 00:02:05.010 --> 00:02:11.190 from the thousand strain gauges placed 31 00:02:06.930 --> 00:02:12.690 on the carrier that passed in the 32 00:02:11.190 --> 00:02:14.670 electromagnetic interference test 33 00:02:12.690 --> 00:02:16.140 chamber radio waves are blasted at the 34 00:02:14.670 --> 00:02:18.480 instrument to see if they will disrupt 35 00:02:16.140 --> 00:02:20.399 its operations the instruments are also 36 00:02:18.480 --> 00:02:21.720 tested to see if they produce any radio 37 00:02:20.400 --> 00:02:26.790 waves that could interfere with other 38 00:02:21.720 --> 00:02:29.810 instruments or systems this is the space 39 00:02:26.790 --> 00:02:29.810 environment chamber 40 00:02:37.060 --> 00:02:41.380 inside this enormous tank spacecraft and 41 00:02:39.880 --> 00:02:43.569 instruments like the new Wide Field 42 00:02:41.380 --> 00:02:46.000 Camera 3 experienced the harshness of 43 00:02:43.569 --> 00:02:47.829 space the air is pumped out to simulate 44 00:02:46.000 --> 00:02:50.709 the vacuum of space and then the real 45 00:02:47.830 --> 00:02:53.020 testing begins this chamber can heat to 46 00:02:50.709 --> 00:02:55.030 a blazing 300 degrees Fahrenheit and 47 00:02:53.020 --> 00:02:57.850 then drop to minus 310 degrees 48 00:02:55.030 --> 00:02:59.860 Fahrenheit in here the spacecraft must 49 00:02:57.850 --> 00:03:02.170 endure the huge temperature extremes it 50 00:02:59.860 --> 00:03:03.940 will experience in orbit as it travels 51 00:03:02.170 --> 00:03:06.790 from full sunshine to the darkness of 52 00:03:03.940 --> 00:03:09.180 Earth's shadow a typical test can take 53 00:03:06.790 --> 00:03:09.179 many weeks 54 00:03:27.710 --> 00:03:32.420 if the spacecraft survives the torture 55 00:03:30.210 --> 00:03:35.460 in here it's pretty much ready for space 56 00:03:32.420 --> 00:03:37.500 if not better it breaks here than after 57 00:03:35.460 --> 00:03:39.330 launch here we have the ability to 58 00:03:37.500 --> 00:03:42.090 understand the problem correct it and 59 00:03:39.330 --> 00:03:44.700 test again all of this testing helps 60 00:03:42.090 --> 00:03:46.470 reduce the risk of failure on orbits and 61 00:03:44.700 --> 00:03:49.519 increase the spacecraft potential for 62 00:03:46.470 --> 00:03:49.520 scientific success
