1
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
