00:00:13,520 --> 00:00:10,230
with spring right around the corner it's

3
00:00:15,470 --> 00:00:13,530
the season for Aurora's also known as

4
00:00:17,090 --> 00:00:15,480
the Northern Lights Aurora's are the

5
00:00:18,830 --> 00:00:17,100
brilliant curtains of colored light that

6
00:00:20,480 --> 00:00:18,840
appear in the night sky in the far

7
00:00:20,950 --> 00:00:20,490
northern or southern regions of the

8
00:00:23,390 --> 00:00:20,960
world

9
00:00:24,800 --> 00:00:23,400
although Aurora's are spectacular to

10
00:00:27,950 --> 00:00:24,810
watch they're actually a manifestation

11
00:00:31,220 --> 00:00:27,960
of violent space weather these are just

12
00:00:33,560 --> 00:00:31,230
caused by energy coming into us magnetic

13
00:00:35,750 --> 00:00:33,570
atmosphere causing the whole magnetic

14
00:00:37,430 --> 00:00:35,760
field to reconfigure and end up with an

15
00:00:39,709 --> 00:00:37,440
explosive release of high-energy

16
00:00:42,020 --> 00:00:39,719
electrons and protons into our Earth's

17
00:00:44,330 --> 00:00:42,030
atmosphere where they strike the

18
00:00:48,590 --> 00:00:44,340
molecules both oxygen and nitrogen and

19
00:00:50,630 --> 00:00:48,600
cause them to glow besides igniting the

20
00:00:52,520 --> 00:00:50,640
Northern Lights these sub storms can

21
00:00:55,189 --> 00:00:52,530
create big problems here on earth by

22
00:00:58,600 --> 00:00:55,199
disrupting power grids satellites air

23
00:01:01,040 --> 00:00:58,610
travel and even GPS signals

24
00:01:03,140 --> 00:01:01,050
spring is one of the best times to view

25
00:01:05,000 --> 00:01:03,150
the Aurora's because of sub storms that

26
00:01:07,850 --> 00:01:05,010
spark them are more frequent in the

27
00:01:09,590 --> 00:01:07,860
months around the equinoxes plus the

28
00:01:12,560 --> 00:01:09,600
longer nights provide a great backdrop

29
00:01:14,540 --> 00:01:12,570
for these stunning displays while

30
00:01:16,430 --> 00:01:14,550
Aurora's have fascinated observers for

31
00:01:18,830 --> 00:01:16,440
centuries little had been known about

32
00:01:20,540 --> 00:01:18,840
their origin but NASA's aiming to

33
00:01:22,070 --> 00:01:20,550
resolve this mystery with a new mission

34
00:01:25,640 --> 00:01:22,080
to study the Northern Lights called

35
00:01:28,190 --> 00:01:25,650
feminists the Sema's mission uses five

36
00:01:30,109 --> 00:01:28,200
identical satellites and a network of

37
00:01:31,640 --> 00:01:30,119
ground observatories to track and

38
00:01:34,550 --> 00:01:31,650
determine what triggers the Aurora's

39
00:01:36,710 --> 00:01:34,560
that occur during sub storms and since

40
00:01:39,410 --> 00:01:36,720
it's launched just last year temas has

41
00:01:41,180 --> 00:01:39,420
made some important discoveries even in

42
00:01:43,580 --> 00:01:41,190
the first days of our mission we've used

43
00:01:45,920 --> 00:01:43,590
the five spacecraft in the dedicated

44
00:01:49,190 --> 00:01:45,930
array of ground observatories to track

45
00:01:51,469 --> 00:01:49,200
aurora racing westward across canada and

46
00:01:54,410 --> 00:01:51,479
alaska and time their motion and

47
00:01:55,639 --> 00:01:54,420
understand where they occur as our

48
00:01:58,580 --> 00:01:55,649
knowledge about the Northern Lights

49
00:02:02,250 --> 00:01:58,590
continues to expand pretty soon Aurora's
