1 00:00:00,120 --> 00:00:04,330 For most people, a total solar eclipse lasts just a few minutes. 2 00:00:04,330 --> 00:00:07,160 But NASA's pilots find a way to make it last longer 3 00:00:07,160 --> 00:00:09,180 by trying to outrun the Moon’s shadow 4 00:00:09,180 --> 00:00:11,340 with an airplane. 5 00:00:11,340 --> 00:00:12,640 The truth is it's actually chasing us. 6 00:00:12,640 --> 00:00:15,240 We get out in front of it and let it overtake us. 7 00:00:15,240 --> 00:00:16,520 Once we're in totality, 8 00:00:16,520 --> 00:00:18,440 then we'll advance the throttles to max 9 00:00:18,440 --> 00:00:20,860 and try and stay in totality for as long as we can. 10 00:00:20,860 --> 00:00:23,880 Making that happen takes extreme precision. 11 00:00:23,880 --> 00:00:28,550 Scientists calculate exactly where the airplane needs to be at each moment. 12 00:00:28,550 --> 00:00:33,060 We do a lot of missions where being in the right point in time and space are critical 13 00:00:33,060 --> 00:00:34,290 and this is one of them. 14 00:00:34,290 --> 00:00:35,730 On eclipse day, 15 00:00:35,730 --> 00:00:40,700 the WB-57 aircraft climbs more than 50,000 feet into the stratosphere. 16 00:00:40,700 --> 00:00:42,930 That’s above most of Earth's atmosphere, 17 00:00:42,930 --> 00:00:46,380 where clouds, dust, and water vapor could obscure the view. 18 00:00:46,380 --> 00:00:51,770 Viewing an eclipse from 50,000 feet provides a really clear shot of the Sun 19 00:00:51,770 --> 00:00:55,570 and that allows the scientists to have confidence that the data 20 00:00:55,570 --> 00:00:59,210 they're seeing is from the Sun rather than distortions from the atmosphere. 21 00:00:59,210 --> 00:01:03,180 When the Moon’s shadow arrives, it engulfs the aircraft. 22 00:01:03,180 --> 00:01:06,890 It’s weird. Right where you’re at it’s dark but everywhere you see, it's twilight. 23 00:01:06,890 --> 00:01:10,010 The temperature in the cockpit drops, so it’s very noticeable.  24 00:01:10,010 --> 00:01:11,530 As the eclipse unfolds, 25 00:01:11,530 --> 00:01:13,670 the pilot keeps the aircraft on course 26 00:01:13,670 --> 00:01:18,250 while the sensor operator fine-tunes the cameras, capturing every second of data. 27 00:01:18,250 --> 00:01:20,020 You're very, very, very busy 28 00:01:20,020 --> 00:01:24,050 and it's very high pressure because, of course, there's no do-overs. 29 00:01:24,050 --> 00:01:29,090 You only get one opportunity to get all these instruments trained on the right spot. 30 00:01:29,090 --> 00:01:30,630 For the aircraft crew, 31 00:01:30,630 --> 00:01:33,900 it’s a chance to witness one of nature's most spectacular events 32 00:01:33,900 --> 00:01:36,630 while helping scientists better understand our Sun. 33 00:01:36,630 --> 00:01:38,140 I'm sitting in the best seat in the house 34 00:01:38,140 --> 00:01:39,610 — it's pretty exciting. 35 00:01:39,610 --> 00:01:45,003
