1 00:00:00,000 --> 00:00:05,320 Nasa is committed to the safety and future of human spaceflight. 2 00:00:05,320 --> 00:00:10,160 With one final test, NASA’s Space Launch System rocket structural design is officially ready for flight. 3 00:00:10,220 --> 00:00:15,200 Engineers pushed the liquid oxygen tank structural test article to its limits in June 2020. 4 00:00:15,260 --> 00:00:19,200 The final test concludes a three year structural test campaign for the deep space rocket. 5 00:00:19,260 --> 00:00:22,220 Teams conducted 199 test cases and collected more than 420 gigabytes of data. 6 00:00:23,160 --> 00:00:31,300 The SLS rocket will power NASA’s Artemis missions to send astronauts to the Moon. 7 00:00:31,360 --> 00:00:36,220 NASA teams use exact replicas of the flight hardware, called structural test articles. 8 00:00:36,280 --> 00:00:38,400 The structural test articles are installed in test stands 9 00:00:38,460 --> 00:00:40,340 at NASA’s Marshall Space Flight Center in Huntsville, Alabama. 10 00:00:40,540 --> 00:00:43,200 Hydraulic systems push and pull on the hardware 11 00:00:43,280 --> 00:00:45,240 to simulate what the rocket will experience during launch and flight. 12 00:00:45,320 --> 00:00:49,140 Most structural testing includes baseline testing. 13 00:00:49,260 --> 00:00:55,260 But, NASA engineers also want to verify exactly how strong the SLS rocket hardware is. 14 00:00:55,340 --> 00:01:00,140 That kind of testing pushes the hardware until it fails. 15 00:01:00,960 --> 00:01:04,780 Because engineers apply forces much stronger 16 00:01:04,860 --> 00:01:09,240 than what they expect the hardware to endure… 17 00:01:09,540 --> 00:01:18,380 Sometimes the hardware pops and twists like a soda can.
