00:00:20.120 --> 00:00:21.621
So the GOES-R series is NOAA’s

2
00:00:21.621 --> 00:00:23.957
current
generation of geostationary satellites

3
00:00:23.957 --> 00:00:26.943
and these are the satellites that are
stationed permanently over the U.S..

4
00:00:27.210 --> 00:00:29.245
So that they can constantly monitor

5
00:00:29.245 --> 00:00:32.365
weather and other hazardous environmental
conditions for the for the U.S.

6
00:00:32.365 --> 00:00:38.354
and our neighbors
throughout the hemisphere.

7
00:00:38.354 --> 00:00:42.542
GOES-U

8
00:00:42.542 --> 00:00:47.447
is in fact the last.

9
00:00:47.447 --> 00:00:49.682
The fourth and final of the GOES-R series.

10
00:00:49.682 --> 00:00:52.452
And we actually have an extra passenger
on GOES-U.

11
00:00:52.469 --> 00:00:56.239
We've added to GOES-U a new instrument
that's designed to do space

12
00:00:56.239 --> 00:01:04.948
weather monitoring.

13
00:01:07.550 --> 00:01:08.518
The new instrument is called

14
00:01:08.518 --> 00:01:11.538
the compact coronagraph,
and it's designed to look at the Sun

15
00:01:11.538 --> 00:01:16.309
and the coronal area around the Sun,
specifically for coronal mass ejections.

16
00:01:16.709 --> 00:01:21.781
These are masses, tons really, of charged
particles that the Sun ejects.

17
00:01:22.082 --> 00:01:25.769
And if those come towards the earth,
they can affect things that people care

18
00:01:25.769 --> 00:01:28.338
about, like electrical power,
like radio signals, and G.P.S.

19
00:01:28.404 --> 00:01:33.927
signals.

20
00:01:33.927 --> 00:01:40.950
GOES-U has advanced instrumentation.

21
00:01:40.950 --> 00:01:42.836
It has a camera that can zoom in

22
00:01:42.836 --> 00:01:46.289
and look at dangerous phenomena
as often as every 30 seconds.

23
00:01:46.623 --> 00:01:49.442
It's also got a lightning mapper
that's designed to look for lightning

24
00:01:49.442 --> 00:01:52.645
activity as often as 500 times a second.

25
00:01:52.679 --> 00:01:56.850
So in combination,
those two instruments can look at any kind

26
00:01:56.850 --> 00:02:00.203
of dangerous activity that's happening
across the hemisphere, whether that's

27
00:02:00.737 --> 00:02:04.107
tornadoes or floods, ice
or snow even looks for

28
00:02:04.107 --> 00:02:11.848
volcanic ash and fires.

29
00:02:16.669 --> 00:02:19.005
Yeah,
it's a little like the cycle of life .

30
00:02:19.005 --> 00:02:22.492
GOES-U represents
the end of the GOES-R development stage.

31
00:02:23.343 --> 00:02:25.645
But the GOES-U satellite will continue
observing

32
00:02:25.912 --> 00:02:30.116
long into the future
but it also represents the bridge.

33
00:02:30.116 --> 00:02:31.818
GOES-U will be the bridge
that actually takes us

34
00:02:31.818 --> 00:02:35.004
to the next generation of satellites
called GeoXo.

35
00:02:45.632 --> 00:02:47.217
Just search for NOAA's

36
00:02:47.217 --> 00:03:03.449
satellites in your browser
or on social media.

37
00:03:05.635 --> 00:03:08.004
Yeah, it's important
to never run out of weather satellites

38
00:03:08.004 --> 00:03:12.659
and so NOAA's already planning
the next generation series called GeoXO.

39
00:03:12.659 --> 00:03:16.713
GeoXO is going to add capabilities,
including an ocean color instrument

40
00:03:16.713 --> 00:03:18.181
to look at coastal conditions

41
00:03:18.181 --> 00:03:21.601
and an air quality instrument
to look for pollution across the U.S.

42
00:03:21.985 --> 00:03:25.922
So those instruments combined with the
the continuity of the current instruments,

43
00:03:26.122 --> 00:03:30.260
will give a very comprehensive view
of dangerous phenomena

44
00:03:30.260 --> 00:03:31.427
that might affect the U.S.

45
00:03:31.427 --> 00:03:32.845
and it'll really help us address

46
00:03:32.845 --> 00:03:37.050
the challenges of climate change,
things like intensifying hurricanes,

47
00:03:37.250 --> 00:03:42.272
more prevalent harmful
algal blooms and more prevalent wildfires.

48
00:03:52.849 --> 00:03:55.318
GOES-U is destined to be our goes East
satellite.

49
00:03:55.318 --> 00:03:58.104
That means it'll be stationed
off the east coast of the U.S.

50
00:03:58.671 --> 00:04:00.540
From there it can see all of the U.S.

51
00:04:00.540 --> 00:04:05.161
It's also a good spot for it to track
areas of the Caribbean and South America.

52
00:04:05.428 --> 00:04:09.415
And it can also see all the way
across the Atlantic to Europe and Africa,

53
00:04:09.649 --> 00:04:12.602
which is important because the hurricanes
that affect the East Coast

54
00:04:12.602 --> 00:04:23.846
really start out in the Atlantic
and come towards us from that direction.

55
00:04:26.299 --> 00:04:28.351
Geostationary is a unique orbit,

56
00:04:28.584 --> 00:04:32.422
the height of the orbit, which is 22,000
miles above the surface of the Earth,

57
00:04:33.172 --> 00:04:35.642
actually puts it
so that the rotation rate of the satellite

58
00:04:35.642 --> 00:04:37.677
matches the rotation rate of the Earth.

59
00:04:37.677 --> 00:04:41.881
And so that means that the satellite is
always looking at the same place on Earth.

60
00:04:42.081 --> 00:04:45.385
And that's really important if you're
trying to watch a storm continuously.

61
00:04:45.918 --> 00:04:47.553
That's what
the geostationary orbit does for you.
