1 00:00:01,919 --> 00:00:04,551 Well, were the final preparation before 2 00:00:04,586 --> 00:00:07,446 we get to ignite Ares Demonstration Motor 3 00:00:07,481 --> 00:00:10,506 number two, which is a large five segment 4 00:00:10,541 --> 00:00:13,381 solid rocket motor which we have been 5 00:00:13,416 --> 00:00:16,459 preparing for this test for well over a year. 6 00:00:16,494 --> 00:00:18,839 One of the interesting objectives of this 7 00:00:18,874 --> 00:00:21,273 test is we want to demonstrate how this motor 8 00:00:21,308 --> 00:00:23,784 preforms at cold temperatures. So, were here 9 00:00:23,819 --> 00:00:26,347 in the middle of the summer in Utah, where it's 10 00:00:26,382 --> 00:00:28,812 a hundred degrees outside and Shyla Quinn, 11 00:00:28,847 --> 00:00:31,018 one of our young mechanical engineers has had 12 00:00:31,053 --> 00:00:32,978 an assignment for the last year to figure out 13 00:00:33,013 --> 00:00:35,250 a way to chill this motor down to fourty degrees 14 00:00:35,285 --> 00:00:37,760 so when we static test it, we will be actually 15 00:00:37,795 --> 00:00:40,269 demonstrating our rocket as if it were launching 16 00:00:40,304 --> 00:00:42,530 in the winter time in Florida. Basically, we 17 00:00:42,565 --> 00:00:44,822 have been asked to cool down the PMBT, which is 18 00:00:44,857 --> 00:00:46,871 the propellent mean bulk temperature about fourty 19 00:00:46,906 --> 00:00:49,164 degrees lower than what is would normally be. 20 00:00:49,199 --> 00:00:51,791 We have 2 two hundred ton chillers, it can go all 21 00:00:51,826 --> 00:00:54,676 the way down to negative ten degrees. Were putting 22 00:00:54,711 --> 00:00:58,328 in any where from 15 degrees air into that building 23 00:00:58,363 --> 00:01:02,010 and we are actually able to, as of a week ago, get 24 00:01:02,045 --> 00:01:05,025 down to thirty seven degrees on our PMBT, so we 25 00:01:05,060 --> 00:01:07,319 actually made our goal ahead of schedule. So on 26 00:01:07,354 --> 00:01:09,844 test morning, the motor will be fourty degrees or 27 00:01:09,879 --> 00:01:12,724 below, we'll be able to meet out test objectives 28 00:01:12,759 --> 00:01:15,793 and we'll be able to release twenty two million 29 00:01:15,828 --> 00:01:18,571 horse power at fourty degrees in the middle of 30 00:01:18,606 --> 00:01:20,531 summer in Utah. It's amazing, it's like as soon 31 00:01:20,566 --> 00:01:23,039 as you walk in the door, you kind of get hit with 32 00:01:23,074 --> 00:01:25,883 this wave of cold and it almost instantly takes 33 00:01:25,918 --> 00:01:28,919 your breath away but you quickly get aclimated to 34 00:01:28,954 --> 00:01:31,310 it but you do get shocked when you're out in this 35 00:01:31,345 --> 00:01:33,712 bright sun, shining down on you, a hundred degrees, 36 00:01:33,747 --> 00:01:36,038 you walk in and you're like "whoa!", that was a 37 00:01:36,073 --> 00:01:38,580 little cold. Poor operators having to work in there, 38 00:01:38,615 --> 00:01:41,821 we're all in cold weather gear and like Kevin was 39 00:01:41,856 --> 00:01:45,063 saying, were at ninety degrees a hundred, degrees 40 00:01:45,098 --> 00:01:47,713 outside and you walk in and everyone is in their 41 00:01:47,748 --> 00:01:50,226 hats and their cold weather gear, working away. 42 00:01:50,261 --> 00:01:52,517 I did have a couple of operators tell me that they 43 00:01:52,552 --> 00:01:55,156 kinda hated me a little bit for making it cold. 44 00:01:55,191 --> 00:01:57,407 They gave me the nickname of being the ice queen 45 00:01:57,442 --> 00:01:59,206 obviously because were getting it so cold and I 46 00:01:59,241 --> 00:02:01,220 told them I'd rather be a cool lady than a hot one, 47 00:02:01,255 --> 00:02:05,365 so nice and cool. So on test morning, the motor 48 00:02:05,400 --> 00:02:08,759 will be fourty degrees or below and we will be able 49 00:02:08,794 --> 00:02:11,591 meet out test objectives and we'll be able to
