00:00:00.070 --> 00:00:02.120
The Portuguese explorer Magellan

2
00:00:02.120 --> 00:00:04.160
left his legacy in the

3
00:00:04.160 --> 00:00:06.190
first circumnavigation of planet Earth.

4
00:00:06.190 --> 00:00:08.240
Our first orbital experience on

5
00:00:08.240 --> 00:00:10.290
our home planet. And today

6
00:00:10.290 --> 00:00:12.370
looking forward 500 years from that

7
00:00:12.370 --> 00:00:14.450
first voyage, we see the

8
00:00:14.450 --> 00:00:16.550
expansive space, the cosmic ocean

9
00:00:16.550 --> 00:00:18.650
that we've since conquered. And today

10
00:00:18.650 --> 00:00:20.740
as we look forward beyond the legacy

11
00:00:20.740 --> 00:00:22.860
of Magellan, we can see where we'll go

12
00:00:22.860 --> 00:00:24.990
in the next 500 years

13
00:00:24.990 --> 00:00:28.020
into that forever frontier.

14
00:00:28.020 --> 00:00:31.200
Earth.

15
00:00:31.200 --> 00:00:33.390
The ocean planet.

16
00:00:33.390 --> 00:00:35.570
The Portuguese explorer Magellan

17
00:00:35.570 --> 00:00:37.600
gave us the first orbit of our

18
00:00:37.600 --> 00:00:39.630
home planet 500 years ago.

19
00:00:39.630 --> 00:00:41.700
Today we see Earth through new eyes

20
00:00:41.700 --> 00:00:43.720
satellite views that show us

21
00:00:43.720 --> 00:00:45.750
the Earth's oceans that Magellan

22
00:00:45.750 --> 00:00:47.820
experienced himself from space.

23
00:00:47.820 --> 00:00:49.880
Little did he know.

24
00:00:49.880 --> 00:00:51.940
As he sailed the oceans, we can

25
00:00:51.940 --> 00:00:54.040
look forward 500 years to the cosmic

26
00:00:54.040 --> 00:00:56.080
oceans that today we sail.

27
00:00:56.080 --> 00:00:58.210
Magellan's ships carried him around

28
00:00:58.210 --> 00:01:00.350
our Earth in a time

29
00:01:00.350 --> 00:01:02.520
when it was unimaginable.

30
00:01:02.520 --> 00:01:04.670
Now his legacy lives on in space

31
00:01:04.670 --> 00:01:06.730
through spacecraft named for Magellan.

32
00:01:06.730 --> 00:01:08.770
Who set sail from the space shuttle

33
00:01:08.770 --> 00:01:10.960
30 years ago to map our

34
00:01:10.960 --> 00:01:13.070
sister planet Venus

35
00:01:13.070 --> 00:01:15.110
in all of its glory. Perhaps a former

36
00:01:15.110 --> 00:01:17.180
ocean world, as was Earth.

37
00:01:17.180 --> 00:01:19.220
The cosmic ocean calls us

38
00:01:19.220 --> 00:01:21.300
every night across the

39
00:01:21.300 --> 00:01:23.380
Milkyway into the space we now

40
00:01:23.380 --> 00:01:25.470
experience through the eyes of

41
00:01:25.470 --> 00:01:27.590
the Hubble Space Telescope and beyond.

42
00:01:27.590 --> 00:01:29.700
This cosmic ocean is a

43
00:01:29.700 --> 00:01:31.830
forever frontier for humanity

44
00:01:31.830 --> 00:01:33.960
and it lives on in the record

45
00:01:33.960 --> 00:01:36.100
of space exploration.

46
00:01:36.100 --> 00:01:38.180
50 years ago we explored space

47
00:01:38.180 --> 00:01:40.270
from beyond Earth at the moon

48
00:01:40.270 --> 00:01:42.360
as the voyages of project Apollo gave us

49
00:01:42.360 --> 00:01:44.430
Earth rise. You see our ocean

50
00:01:44.430 --> 00:01:46.450
world from the landscapes

51
00:01:46.450 --> 00:01:48.500
and the barren landscapes of our

52
00:01:48.500 --> 00:01:50.580
nearest neighbor, the moon.

53
00:01:50.580 --> 00:01:52.680
Where its seas are frozen in rock.

54
00:01:52.680 --> 00:01:54.800
Today, through spacecraft

55
00:01:54.800 --> 00:01:56.850
known as the Lunar Reconnaissance Orbiter,

56
00:01:56.850 --> 00:01:58.930
we can see the moon up close

57
00:01:58.930 --> 00:02:01.020
as if we were there,

58
00:02:01.020 --> 00:02:03.030
flying over its surface.

59
00:02:03.030 --> 00:02:05.150
We can also imagine

60
00:02:05.150 --> 00:02:07.280
living with a star

61
00:02:07.280 --> 00:02:09.430
our planet's sun.

62
00:02:09.430 --> 00:02:11.450
This sun drives the energy of our

63
00:02:11.450 --> 00:02:13.630
solar system and it shows us what

64
00:02:13.630 --> 00:02:15.840
other stars are like.

65
00:02:15.840 --> 00:02:17.880
Today we set sail to get to know the sun

66
00:02:17.880 --> 00:02:19.910
even better, through a mission known as the

67
00:02:19.910 --> 00:02:21.950
Parker Solar Probe, because the sun's

68
00:02:21.950 --> 00:02:24.010
energy drives the circulation

69
00:02:24.010 --> 00:02:26.050
our oceans and our planet.

70
00:02:26.050 --> 00:02:28.090
We move on to Venus, our sister world.

71
00:02:28.090 --> 00:02:30.160
Where the spacecraft Magellan gave

72
00:02:30.160 --> 00:02:32.250
us the views that carry our

73
00:02:32.250 --> 00:02:34.320
imagination to the cosmic oceans

74
00:02:34.320 --> 00:02:36.400
of this world where we believe it's

75
00:02:36.400 --> 00:02:38.490
oceans were lost in time

76
00:02:38.490 --> 00:02:40.590
billions of years ago.

77
00:02:40.590 --> 00:02:42.730
From Venus on to planet

78
00:02:42.730 --> 00:02:44.900
Mars where we ask the tough questions.

79
00:02:44.900 --> 00:02:46.930
Are we alone? Is this a place we're going?

80
00:02:46.930 --> 00:02:49.110
On Mars we know

81
00:02:49.110 --> 00:02:51.300
the record of water is lurking in the rocks

82
00:02:51.300 --> 00:02:53.330
in its climate history and we looked

83
00:02:53.330 --> 00:02:55.390
beneath its landscapes into

84
00:02:55.390 --> 00:02:57.430
story of those rocks from

85
00:02:57.430 --> 00:02:59.430
the voyages of spacecraft know

86
00:02:59.430 --> 00:03:01.450
as Curiosity.

87
00:03:01.450 --> 00:03:03.510
The Mars Reconnaissance Orbiter.

88
00:03:03.510 --> 00:03:05.550
These spacecrafts show us the rockscapes.

89
00:03:05.550 --> 00:03:07.620
Where the record of the oceans and

90
00:03:07.620 --> 00:03:09.700
seas and the lakes of Mars is written

91
00:03:09.700 --> 00:03:11.780
in the stones of time.

92
00:03:11.780 --> 00:03:13.860
So from Mars we can see

93
00:03:13.860 --> 00:03:15.950
the record of water

94
00:03:15.950 --> 00:03:18.060
in planets like Jupiter, where its

95
00:03:18.060 --> 00:03:20.170
beautiful systems

96
00:03:20.170 --> 00:03:22.290
of clouds and circulation

97
00:03:22.290 --> 00:03:24.460
can be captured with spacecraft through the

98
00:03:24.460 --> 00:03:26.660
minds eyes of humanity.

99
00:03:26.660 --> 00:03:28.830


100
00:03:28.830 --> 00:03:30.870
We move on to the beautiful planet

101
00:03:30.870 --> 00:03:32.970
known as Saturn. Where when we see

102
00:03:32.970 --> 00:03:35.000
Earth at the scale of Saturn

103
00:03:35.000 --> 00:03:37.060
we imagine how small we are

104
00:03:37.060 --> 00:03:39.140
in that cosmic ocean.

105
00:03:39.140 --> 00:03:41.170
From Saturn we can looks at its largest

106
00:03:41.170 --> 00:03:43.230
moon, Titan.

107
00:03:43.230 --> 00:03:45.290
Where oceans exist but now of water.

108
00:03:45.290 --> 00:03:47.340
Little did Magellan know that

109
00:03:47.340 --> 00:03:49.390
these other ocean worlds

110
00:03:49.390 --> 00:03:51.550
would harbor different kinds of fluids.

111
00:03:51.550 --> 00:03:53.580
Today the ocean

112
00:03:53.580 --> 00:03:55.700
universe is dramatic, we see

113
00:03:55.700 --> 00:03:57.730
even at the planet known as Pluto.

114
00:03:57.730 --> 00:03:59.890
Now a dwarf world but

115
00:03:59.890 --> 00:04:02.070
still in its landscapes

116
00:04:02.070 --> 00:04:04.250
the magic of what an ocean world might

117
00:04:04.250 --> 00:04:06.290
have looked like beyond Earth.

118
00:04:06.290 --> 00:04:08.340
It gives us the views we can expect

119
00:04:08.340 --> 00:04:10.370
of oceanic around other

120
00:04:10.370 --> 00:04:12.430
stars, light years away,

121
00:04:12.430 --> 00:04:14.510
unseen by humanity,

122
00:04:14.510 --> 00:04:16.600
but our visioneering of them

123
00:04:16.600 --> 00:04:18.710
carried by the grand telescopes

124
00:04:18.710 --> 00:04:20.810
in space, takes us there,

125
00:04:20.810 --> 00:04:22.950
extends our presents: Hubble

126
00:04:22.950 --> 00:04:24.990
Next up is the James Webb Space Telescope.

127
00:04:24.990 --> 00:04:27.110
A cosmic voyager like

128
00:04:27.110 --> 00:04:29.160
Magellan, launching in 2021.

129
00:04:29.160 --> 00:04:31.310
It will extend our imagination

130
00:04:31.310 --> 00:04:33.450
to those worlds

131
00:04:33.450 --> 00:04:35.480
and the bigger cosmic ocean landscapes

132
00:04:35.480 --> 00:04:37.650
that we can only see in our minds eye.

133
00:04:37.650 --> 00:04:39.740
Back home to Earth.

134
00:04:39.740 --> 00:04:41.780
The Earth that Magellan experienced

135
00:04:41.780 --> 00:04:43.810
can be now experienced from space

136
00:04:43.810 --> 00:04:45.850
in the same way that Magellan

137
00:04:45.850 --> 00:04:47.860
experienced sailing it.

138
00:04:47.860 --> 00:04:49.910
From the record of biology on Earth

139
00:04:49.910 --> 00:04:51.990
and circulation and energy

140
00:04:51.990 --> 00:04:54.060
we can come home to the Iberian Peninsula

141
00:04:54.060 --> 00:04:56.140
were Magellan set sail

142
00:04:56.140 --> 00:04:58.280
500 years ago

143
00:04:58.280 --> 00:05:00.440
and today thanks to Jose Marquez and his team

144
00:05:00.440 --> 00:05:02.600
we commemorate the 500th

145
00:05:02.600 --> 00:05:04.770
anniversary of our oceanic

146
00:05:04.770 --> 00:05:06.800
exploration that carries us forward today

147
00:05:06.800 --> 00:05:08.980
to the exploration of deep space.

148
00:05:08.980 --> 00:05:11.160
The forever frontier.

149
00:05:11.160 --> 00:05:13.190
Thanks to you Magellan

150
00:05:13.190 --> 00:05:15.240
we're there.

151
00:05:15.240 --> 00:05:17.260


152
00:05:17.260 --> 00:05:19.310


153
00:05:19.310 --> 00:05:21.330


154
00:05:21.330 --> 00:05:23.390


155
00:05:23.390 --> 00:05:25.400


156
00:05:25.400 --> 00:05:26.826
