00:00:20.040 --> 00:00:26.580
These are sounds of our times. Called
telemetry, it is the way satellites

3
00:00:26.599 --> 00:00:31.550
orbiting in space report to controllers
on Earth. Each spacecraft has its own

4
00:00:31.550 --> 00:00:40.850
signature, a unique tone. Engineers call
it beta, you may see it later as a

5
00:00:40.850 --> 00:00:46.180
weather report or a television picture
from around the world.

8
00:01:13.520 --> 00:01:19.300
doing for you now and what will be
happening in the decade of the 70s.

9
00:01:19.300 --> 00:01:26.270
Weather, communications, Earth resources. These will be among the main topics for

10
00:01:26.270 --> 00:01:34.040
dialogue in the 1970s. Each has its own
type of impact on our lifestyles.

11
00:01:34.040 --> 00:01:40.380
At times we will be more concerned about one than the other but always they will be there.

00:01:44.740 --> 00:01:53.710
Case in point, weather. Spacecraft like
TIROS, Nimbus and the application

14
00:01:53.710 --> 00:01:58.600
technology satellites. Satellites that
return daily weather information over

15
00:01:58.600 --> 00:02:04.990
the entire world. What do they report? A
continuous watch of the Earth's moving

16
00:02:04.990 --> 00:02:10.899
cloud cover, tracking storms, measuring
winds, recording temperatures at

17
00:02:10.899 --> 00:02:15.730
different heights and testing the
moisture content of the atmosphere. As a

18
00:02:15.730 --> 00:02:20.800
result computer systems are built that
can receive and analyze vast amounts of

19
00:02:20.800 --> 00:02:26.140
global information from many sources.
Making forecasting more accurate.

20
00:02:26.140 --> 00:02:30.560
(Hurricane high wind sounds)

21
00:02:30.560 --> 00:02:35.800
Hurricanes with their devastating winds
and flood causing rains, a perennial

22
00:02:35.800 --> 00:02:42.310
threat. In 1969 Hurricane Camille was
first observed and then tracked by

23
00:02:42.310 --> 00:02:47.170
satellite. Because the storms arrival was
predicted accurately enough in advance

24
00:02:47.170 --> 00:02:52.750
it was possible to evacuate people from
the Gulf Coast. Without this early

25
00:02:52.750 --> 00:02:56.739
warning, the weather bureau estimated
that 50,000 people might have been

26
00:02:56.739 --> 00:03:04.269
killed. In contrast during Hurricane Laurie in November 1969, observations and

27
00:03:04.269 --> 00:03:07.959
tracking by satellite enabled the
weather forecasters to predict that

28
00:03:07.959 --> 00:03:12.880
Laurie would not strike the coast. It is
estimated that three million dollars was

29
00:03:12.880 --> 00:03:17.680
saved from this satellite prompted
decision not to evacuate and not to

30
00:03:17.680 --> 00:03:21.000
protect property.

31
00:03:21.000 --> 00:03:28.280
TIROS, Television Infrared Operational
Satellite, over the past ten years twenty

32
00:03:28.280 --> 00:03:32.000
of these hat box shaped satellites have
been successfully launched for use by

33
00:03:32.000 --> 00:03:37.160
NASA and the weather bureau. The
television eyes of TIROS scanned the

34
00:03:37.160 --> 00:03:44.120
entire globe daily reporting on cloud
cover and warning of major storms. Since

35
00:03:44.120 --> 00:03:48.350
the first operational weather satellites
started clicking off pictures, roughly

36
00:03:48.350 --> 00:03:53.330
600 severe storms have been detected.
followed and predictions made about

37
00:03:53.330 --> 00:03:57.440
their course. They have sent back more
than a million pictures of weather

38
00:03:57.440 --> 00:04:03.980
conditions around the globe. Cameras
onboard the application's technology

39
00:04:03.980 --> 00:04:08.780
satellite scan the Earth and return
color images as often as every 20

40
00:04:08.780 --> 00:04:10.960
minutes.

Music

42
00:04:15.140 --> 00:04:23.039
Here's a view showing six hurricanes on
one picture. This near-continuous

43
00:04:23.039 --> 00:04:28.050
surveillance of 40% of the Earth's
surface has proven so useful, that the

44
00:04:28.050 --> 00:04:32.070
reports have been incorporated into
routine weather forecasts. And have

45
00:04:32.070 --> 00:04:37.070
pointed the way for even more
sophisticated meteorological satellites.

46
00:04:37.070 --> 00:04:43.050
Major airlines make use of satellite
data in planning their flights. Pilots

47
00:04:43.050 --> 00:04:52.800
routinely receive weather photos of
their transoceanic routes. Before

48
00:04:52.800 --> 00:04:57.330
satellite tracking of hurricanes US Navy
Hurricane Hunters had to search out the

49
00:04:57.330 --> 00:05:02.910
killer storms. Weather satellites now
locate the storms and the Navy flies

50
00:05:02.910 --> 00:05:06.540
directly to them to make their
measurements.

51
00:05:06.540 --> 00:05:09.900
(Ice breaking)

52
00:05:09.920 --> 00:05:18.180
The Navy also uses weather satellite
pictures for ice patrols. Remote stations

53
00:05:18.190 --> 00:05:23.319
in the Antarctic benefit to, giant
resupply ski planes can be safely

54
00:05:23.319 --> 00:05:27.220
scheduled for landings in the icy
outposts without worrying about being

55
00:05:27.220 --> 00:05:34.990
trapped by snowstorms. Supply ships
benefit from improved scheduling as well.

56
00:05:34.990 --> 00:05:43.389
A recent satellite in the TIROS series
does the work of two spacecraft. Carrying

57
00:05:43.389 --> 00:05:47.860
twice as many cameras, it's capable of
discerning cloud formations as small as

58
00:05:47.860 --> 00:05:56.380
two miles across. The improved TIROS
operational satellite carries a proton

59
00:05:56.380 --> 00:06:01.659
monitoring instrument, that helps spot
solar flares. The same instrument can

60
00:06:01.659 --> 00:06:05.139
measure the amount of heat reflected
from and absorbed by the Earth's

61
00:06:05.139 --> 00:06:09.780
atmosphere. This is very important in
weather forecasting.

62
00:06:09.780 --> 00:06:15.070
In addition, radio frequencies affected
by solar storms can be changed in

63
00:06:15.070 --> 00:06:19.360
advance and man flights to the moon
better planned.

Music

65
00:06:25.840 --> 00:06:31.080
Nimbus, research and development craft
studying advanced techniques and

66
00:06:31.090 --> 00:06:37.720
concepts for meteorological Earth
observations. Nimbus is measuring the

67
00:06:37.720 --> 00:06:40.960
atmospheres temperature and moisture at various altitudes.

68
00:06:40.960 --> 00:06:46.569
As well as making day and nighttime
cloud photographs. These measurements are

69
00:06:46.569 --> 00:06:52.060
considered the key to accurate
long-range weather forecasts. By the end

70
00:06:52.060 --> 00:06:57.099
of this decade forecasts made one week
in advance will be as accurate as those

71
00:06:57.099 --> 00:07:07.659
now made 24 or 48 hours ahead. Satellites and weather are global in nature. Every

72
00:07:07.659 --> 00:07:11.620
nation in the world can benefit from the
automatic picture transmissions of US

73
00:07:11.620 --> 00:07:17.259
weather satellites. Over 50 countries are
now using inexpensive automatic picture

74
00:07:17.259 --> 00:07:23.440
readout equipment to view daily weather
patterns over their own territory. These

75
00:07:23.440 --> 00:07:28.210
same countries also benefit from cloud
picture mosaics routinely made available

76
00:07:28.210 --> 00:07:33.669
by the weather bureau to Europe, Asia,
Australia and North and South America.

77
00:07:33.669 --> 00:07:40.150
The weather mosaic is built up from
individual weather photos and processed

78
00:07:40.150 --> 00:07:48.550
by computer. It is then retransmitted by
a satellite. There are three main

79
00:07:48.550 --> 00:07:55.240
objectives for an effective
meteorological program. The first global

80
00:07:55.240 --> 00:08:01.389
cloud cover photography. Enabling us to
identify and track storms and to observe

81
00:08:01.389 --> 00:08:06.880
their formation and dissipation. This is
valuable in the analysis of current

82
00:08:06.880 --> 00:08:15.389
weather and the prediction of 24 to
36-hour changes. The second objective.

83
00:08:15.389 --> 00:08:20.350
continuous viewing of the atmosphere.
Needed to keep significant portions of

84
00:08:20.350 --> 00:08:24.310
the Earth's cloud cover under constant
surveillance and providing essential

85
00:08:24.310 --> 00:08:29.860
early warning on rapidly developing
weather phenomena, such as thunderstorms

86
00:08:29.860 --> 00:08:38.620
and the formation growth and death of
tornadoes. This information is valuable

87
00:08:38.620 --> 00:08:47.680
for short period forecasts of less than
12 hours. The third objective. a global

88
00:08:47.680 --> 00:08:54.250
atmospheric research program. It's goal
long-range weather prediction on a

89
00:08:54.250 --> 00:09:02.080
worldwide basis. In 1976 scientists from
governments, industries and universities

90
00:09:02.080 --> 00:09:06.490
in many countries will meet to work out
the problems of International weather

91
00:09:06.490 --> 00:09:13.360
forecasting. The global research program
will use computers to design and test

92
00:09:13.360 --> 00:09:18.700
theoretical models of atmospheric
behavior. When the mathematical models

93
00:09:18.700 --> 00:09:23.680
are combined with information returned
from already operating satellites, it may

94
00:09:23.680 --> 00:09:31.050
be possible to make forecasts two to
three weeks in advance. Communications,

95
00:09:31.050 --> 00:09:35.770
some of the greatest strides in putting
space to work have taken place in this

96
00:09:35.770 --> 00:09:45.820
field. In 1960 Americans made 100 billion
telephone calls. In 1969 nearly 200

97
00:09:45.820 --> 00:09:51.160
billion were made. New uses are
continually being found for

98
00:09:51.160 --> 00:10:06.390
telecommunications. Banks, stock exchanges,
hotel reservations, cable TV, hospitals,

99
00:10:06.390 --> 00:10:13.019
computer centers and other new customers
are appearing at an increasing rate.

100
00:10:13.019 --> 00:10:19.959
We are in the midst of a global
communications explosion. Helping meet

101
00:10:19.960 --> 00:10:23.660
this demand our communications
satellites.

102
00:10:23.660 --> 00:10:29.800
(Eisenhower) "This is President Eisenhower speaking. It is a great personal satisfaction

103
00:10:29.800 --> 00:10:37.800
to participate in this experiment in communication involving the use of the satellite balloons known

104
00:10:37.810 --> 00:10:46.180
as Echo." August 12, 1960, President
Eisenhower took part in the historic

105
00:10:46.180 --> 00:10:52.480
first transmission via Escho satellite. By
bouncing radio waves off its shiny

106
00:10:52.480 --> 00:10:57.160
surface it made possible long-distance
telephone conversations and the

107
00:10:57.160 --> 00:11:03.660
transmission of photographs and music.
Other communication satellites followed

108
00:11:03.660 --> 00:11:11.949
Telstar, Relay,
SIMCom, each a research step leading to

109
00:11:11.949 --> 00:11:18.000
commercial spacecraft capable of
handling satellite communications. In

110
00:11:18.000 --> 00:11:23.259
1964 television viewers around the world
were able to watch the Olympics from

111
00:11:23.259 --> 00:11:32.259
Tokyo. A visit to Mexico City by the Pope
was also viewed globally. Over half a

112
00:11:32.259 --> 00:11:37.689
billion people one-sixth of the world's
population saw Man's first steps on the

113
00:11:37.689 --> 00:11:39.580
moon.

At the manned spacecraft Center in
Houston,

117
00:11:53.960 --> 00:12:00.080
doctors discussed space medicine and
early cancer detection. The proceedings

118
00:12:00.080 --> 00:12:05.120
were telecast live by a communication
satellite and provided two-way voice

119
00:12:05.120 --> 00:12:10.400
