Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:00,676 --> 00:00:03,509
(inspiring music)
2
00:00:11,050 --> 00:00:13,460
CNDH reports normal status,
3
00:00:13,460 --> 00:00:16,500
our SSR pointers are where we expect them to be,
4
00:00:16,500 --> 00:00:19,590
which means we have reported the expected amount of data.
5
00:00:19,590 --> 00:00:20,600
Oh, copy that.
6
00:00:20,600 --> 00:00:22,943
Looks like we have a data report.
7
00:00:22,943 --> 00:00:25,680
(people applauding)
8
00:00:25,680 --> 00:00:29,720
We have a healthy spacecraft and recorded data
9
00:00:29,720 --> 00:00:33,083
of the Pluto system, and we're outbound for Pluto.
10
00:00:34,013 --> 00:00:37,180
(audience applauding)
11
00:00:38,568 --> 00:00:40,470
In 2015, the New Horizons mission
12
00:00:40,470 --> 00:00:42,890
changed our understanding of the solar system
13
00:00:42,890 --> 00:00:45,205
as it rocketed past Pluto,
14
00:00:45,205 --> 00:00:46,630
(gentle music)
15
00:00:46,630 --> 00:00:49,550
providing breathtaking, never before seen images
16
00:00:49,550 --> 00:00:52,411
of the dwarf planet in exquisite detail.
17
00:00:52,411 --> 00:00:53,740
(gentle music)
18
00:00:53,740 --> 00:00:56,060
Pluto becomes a known world,
19
00:00:56,060 --> 00:00:57,870
but nothing is quite as startling
20
00:00:57,870 --> 00:01:00,243
as the colors seen in this composite portrait.
21
00:01:01,690 --> 00:01:04,310
Blue, red, and infrared images
22
00:01:04,310 --> 00:01:07,083
resolve details as small as 8/10 of a mile.
23
00:01:08,948 --> 00:01:11,050
(gentle music)
24
00:01:11,050 --> 00:01:12,920
Pluto is far more active and diverse
25
00:01:12,920 --> 00:01:16,950
than even my imagination said it was gonna be.
26
00:01:16,950 --> 00:01:21,110
That's okay, 'cause every time we've gone to a new place,
27
00:01:21,110 --> 00:01:24,263
we always find our imaginations are never up to the task.
28
00:01:25,910 --> 00:01:27,630
24 hours after passing through
29
00:01:27,630 --> 00:01:30,440
the Pluto-Charon system, New Horizons
30
00:01:30,440 --> 00:01:33,230
is nearly a million miles behind the planet,
31
00:01:33,230 --> 00:01:36,090
making its way toward its next target,
32
00:01:36,090 --> 00:01:39,700
the Kuiper Belt object designated as Ultima Thule,
33
00:01:39,700 --> 00:01:42,810
what scientists believe to be a potato shaped chunk
34
00:01:42,810 --> 00:01:46,010
45 kilometers across, likely similar
35
00:01:46,010 --> 00:01:48,743
to the Plutonian moons Hydra or Styx.
36
00:01:49,800 --> 00:01:51,930
But it won't be until New Horizons arrives
37
00:01:51,930 --> 00:01:55,670
at Ultima Thule that its true shape will be revealed.
38
00:01:55,670 --> 00:01:59,733
The rendezvous with Ultima Thule is set for January 2019.
39
00:02:00,630 --> 00:02:02,570
By then, New Horizons will be
40
00:02:02,570 --> 00:02:04,443
another billion miles from Pluto.
41
00:02:05,285 --> 00:02:07,868
(gentle music)
42
00:02:10,490 --> 00:02:13,850
By 2017, New Horizons was deep in a realm
43
00:02:13,850 --> 00:02:15,533
of far flung chunks of ice,
44
00:02:16,990 --> 00:02:18,683
but what is this new region?
45
00:02:19,780 --> 00:02:23,380
Science now divides our solar system into three zones,
46
00:02:23,380 --> 00:02:27,950
the innermost planets: Mercury, Venus, Earth, and Mars,
47
00:02:27,950 --> 00:02:30,923
are small, rocky and close to the Sun.
48
00:02:32,120 --> 00:02:33,723
This is the first zone.
49
00:02:34,630 --> 00:02:37,600
The second zone is the domain of gas giants,
50
00:02:37,600 --> 00:02:40,963
Jupiter and Saturn, Uranus and Neptune.
51
00:02:42,250 --> 00:02:44,773
Tiny Pluto marks the outer edge.
52
00:02:45,970 --> 00:02:49,010
Yet, astronomer Gerard Kuiper predicts the existence
53
00:02:49,010 --> 00:02:52,063
of a belt of icy bodies that lie beyond Neptune,
54
00:02:53,120 --> 00:02:55,113
girdling the entire solar system.
55
00:02:56,560 --> 00:02:59,630
A vast flattened plane of icy bodies
56
00:02:59,630 --> 00:03:01,651
now called the Kuiper Belt.
57
00:03:01,651 --> 00:03:03,350
(soft music)
58
00:03:03,350 --> 00:03:06,740
The power levels and dealing with
59
00:03:06,740 --> 00:03:08,250
some other technical challenges,
60
00:03:08,250 --> 00:03:12,470
conspire to make this a tougher and riskier flyby.
61
00:03:12,470 --> 00:03:14,670
In fact, there's one shot I wanna tell you about.
62
00:03:14,670 --> 00:03:16,550
At closest approach, we're gonna try
63
00:03:16,550 --> 00:03:20,200
to image Ultima at three times the resolution
64
00:03:20,200 --> 00:03:21,640
that we had for Pluto.
65
00:03:21,640 --> 00:03:22,760
If we can accomplish that,
66
00:03:22,760 --> 00:03:24,100
it'll be spectacular.
Wow.
67
00:03:24,100 --> 00:03:26,500
But we've gotta shoot at a moving target.
68
00:03:26,500 --> 00:03:29,740
As we go by, we're gonna fire off hundreds of images
69
00:03:29,740 --> 00:03:32,840
hoping to capture it somewhere in that strip.
70
00:03:32,840 --> 00:03:34,180
Wow, yeah.
It requires
71
00:03:34,180 --> 00:03:37,290
extremely precise navigation, much more precise
72
00:03:37,290 --> 00:03:38,540
than we've ever tried before,
73
00:03:38,540 --> 00:03:40,440
and we might get it, and we might not,
74
00:03:40,440 --> 00:03:42,904
and if we get it, it's gonna be spectacular.
75
00:03:42,904 --> 00:03:45,654
(dramatic music)
76
00:03:46,500 --> 00:03:48,630
Three and a half years
77
00:03:48,630 --> 00:03:50,590
after revolutionizing our understanding of Pluto,
78
00:03:50,590 --> 00:03:52,640
the New Horizons spacecraft continues
79
00:03:52,640 --> 00:03:54,313
its journey into deep space.
80
00:03:55,380 --> 00:03:57,160
It's traveled one billion miles
81
00:03:57,160 --> 00:03:59,317
since rocketing past the dwarf planet.
82
00:03:59,317 --> 00:04:01,670
(dramatic music)
83
00:04:01,670 --> 00:04:04,640
Cruising at speeds of almost 10 miles per second,
84
00:04:04,640 --> 00:04:06,940
the piano sized craft beams back
85
00:04:06,940 --> 00:04:08,503
early pictures of Ultima Thule,
86
00:04:09,734 --> 00:04:13,760
and it's not a potato shaped object, as once believed.
87
00:04:13,760 --> 00:04:16,349
Instead, it resembles a snowman.
88
00:04:16,349 --> 00:04:19,360
(mysterious music)
89
00:04:19,360 --> 00:04:20,680
If you think about it, by analogy,
90
00:04:20,680 --> 00:04:22,890
New Horizons is going to the farthest part
91
00:04:22,890 --> 00:04:25,530
of our solar system and it is very cold and dark
92
00:04:25,530 --> 00:04:28,050
and barren out there, so unlike an asteroid,
93
00:04:28,050 --> 00:04:29,850
which is actually just a piece of rock
94
00:04:29,850 --> 00:04:31,320
that has melted and changed over
95
00:04:31,320 --> 00:04:33,830
with some alteration by some internal water,
96
00:04:33,830 --> 00:04:36,700
Ultima Thule never melted, never differentiated,
97
00:04:36,700 --> 00:04:39,420
never made a core, even like our planet Earth has a core.
98
00:04:39,420 --> 00:04:42,260
All that stuff is just as it came from the galaxy,
99
00:04:42,260 --> 00:04:44,220
we think, and it is just a random
100
00:04:44,220 --> 00:04:47,030
loose snowball of created material.
101
00:04:47,030 --> 00:04:48,780
So we'll see if that's really true.
102
00:04:50,250 --> 00:04:52,930
And on January 1st, 2019,
103
00:04:52,930 --> 00:04:55,070
New Horizons will ring in the new year
104
00:04:55,070 --> 00:04:57,710
by traveling back in time and studying
105
00:04:57,710 --> 00:04:59,993
the earliest days of our solar system.
106
00:04:59,993 --> 00:05:01,890
(gentle music)
107
00:05:01,890 --> 00:05:05,350
The Kuiper Belt is the edge of our very solar system.
108
00:05:05,350 --> 00:05:07,560
It's a part of the original disc
109
00:05:07,560 --> 00:05:09,390
that the sun and the planets formed out of
110
00:05:09,390 --> 00:05:11,080
that's at the very edge, before you just get
111
00:05:11,080 --> 00:05:13,850
into the galaxy and the region between the stars.
112
00:05:13,850 --> 00:05:15,780
And at that very edge of the disc,
113
00:05:15,780 --> 00:05:17,980
there wasn't enough stuff to make giant planets,
114
00:05:17,980 --> 00:05:21,530
and make big stars like our sun.
115
00:05:21,530 --> 00:05:22,780
There was just enough stuff to make
116
00:05:22,780 --> 00:05:24,480
small dwarf planets and snowballs.
117
00:05:25,330 --> 00:05:26,950
New Horizons will fly past
118
00:05:26,950 --> 00:05:30,640
the 20 mile wide asteroid in a split second,
119
00:05:30,640 --> 00:05:33,380
but the images and the data beamed back to earth
120
00:05:33,380 --> 00:05:36,283
will provide scientists with a lifetime of information.
121
00:05:37,440 --> 00:05:41,130
Ultima Thule, we know very little about right now,
122
00:05:41,130 --> 00:05:43,600
but we think it's the most primitive object
123
00:05:43,600 --> 00:05:46,150
ever visited by a spacecraft.
124
00:05:46,150 --> 00:05:49,480
That's preserved, but the material was,
125
00:05:49,480 --> 00:05:51,740
at the time of the formation of the solar system.
126
00:05:51,740 --> 00:05:54,280
If you were on board New Horizons right now,
127
00:05:54,280 --> 00:05:57,450
Ultima Thule would be about as big in the sky
128
00:05:57,450 --> 00:05:59,393
as a full moon over the earth.
129
00:06:00,380 --> 00:06:02,190
So we're gonna start the countdown.
130
00:06:02,190 --> 00:06:03,403
We're almost there.
131
00:06:04,690 --> 00:06:09,690
15, 14, 13, 12, 11, 10,
132
00:06:11,410 --> 00:06:16,410
nine, eight, seven, six, five, four, three, two, one.
133
00:06:19,727 --> 00:06:20,560
(fireworks bursting)
(crowd cheering)
134
00:06:20,560 --> 00:06:22,194
Go New Horizons!
135
00:06:22,194 --> 00:06:23,170
Go New Horizons!
We've just accomplished
136
00:06:23,170 --> 00:06:24,853
the most distant flyby.
137
00:06:26,410 --> 00:06:29,349
We are ready for Ultima Thule's science transmission
138
00:06:29,349 --> 00:06:33,260
(crowd cheering)
at 200 UTC today.
139
00:06:33,260 --> 00:06:35,620
Science to help us understand the origins
140
00:06:35,620 --> 00:06:38,085
of our solar system.
That's it.
141
00:06:38,085 --> 00:06:42,625
(crowd applauding and cheering)
142
00:06:42,625 --> 00:06:47,555
Very nice.
(crowd applauding)
143
00:06:47,555 --> 00:06:50,876
Never seen this before.
144
00:06:50,876 --> 00:06:53,240
Ultima Thule has been sitting at pretty much
145
00:06:53,240 --> 00:06:56,220
the same place, the same distance away from the sun,
146
00:06:56,220 --> 00:06:58,460
for 4.6 billion years.
147
00:06:58,460 --> 00:07:01,900
As relatively small and in a very very cold region of space,
148
00:07:01,900 --> 00:07:04,470
it's been well preserved, it's really,
149
00:07:04,470 --> 00:07:07,273
it's a relic of the formation of the solar system.
150
00:07:07,273 --> 00:07:10,190
(mysterious music)
151
00:07:11,170 --> 00:07:13,330
As data continues to reach earth,
152
00:07:13,330 --> 00:07:16,100
Ultima Thule reveals its true shape
153
00:07:16,100 --> 00:07:19,390
and earlier predictions are proven false.
154
00:07:19,390 --> 00:07:21,150
From the side, the snowman
155
00:07:21,150 --> 00:07:24,146
looks more like two lumpy pancakes,
156
00:07:24,146 --> 00:07:26,130
(bright string music)
157
00:07:26,130 --> 00:07:27,950
providing another clue to the mystery
158
00:07:27,950 --> 00:07:31,393
of our solar system's formation and evolution.
159
00:07:31,393 --> 00:07:33,960
(bright string music)
160
00:07:33,960 --> 00:07:35,790
We know there was a period of time
161
00:07:35,790 --> 00:07:37,530
in the first billion years that this
162
00:07:37,530 --> 00:07:39,520
was a dangerous place to be,
163
00:07:39,520 --> 00:07:40,970
anywhere in the solar system.
164
00:07:42,180 --> 00:07:46,940
One epoch in the past of our solar system,
165
00:07:46,940 --> 00:07:49,163
the giant planets were all moving around.
166
00:07:50,060 --> 00:07:54,240
They are actually plowing into the original Kuiper Belt.
167
00:07:54,240 --> 00:07:57,190
We're only seeing the remnants of the Kuiper Belt right now
168
00:07:58,120 --> 00:08:01,630
and Jupiter, Saturn, Uranus and Neptune
169
00:08:01,630 --> 00:08:04,140
probably plowed into them and just scattered 'em
170
00:08:04,140 --> 00:08:05,283
all over the place.
171
00:08:06,150 --> 00:08:07,210
These scattered bodies
172
00:08:07,210 --> 00:08:11,060
caused numerous collisions, most small.
173
00:08:11,060 --> 00:08:14,010
Some, large, and in the case of Pluto
174
00:08:14,010 --> 00:08:16,580
and one other planet in our solar system,
175
00:08:16,580 --> 00:08:19,913
there was a collision big enough to smash the entire world.
176
00:08:21,270 --> 00:08:26,270
That other planet is Earth, and from the scattered debris,
177
00:08:26,990 --> 00:08:28,163
our Moon was formed.
178
00:08:30,280 --> 00:08:34,340
Astronomers call this period the Late Heavy Bombardment.
179
00:08:34,340 --> 00:08:36,870
The abundant craters across the face of the Moon
180
00:08:36,870 --> 00:08:39,413
are a testament to the violence of this epoch.
181
00:08:40,333 --> 00:08:41,430
(dramatic music)
182
00:08:41,430 --> 00:08:44,300
We think that these large scale collisions
183
00:08:44,300 --> 00:08:47,290
between planets early in the formation era
184
00:08:47,290 --> 00:08:50,140
of solar systems are common, and in computer models,
185
00:08:50,140 --> 00:08:51,603
we see that happens a lot.
186
00:08:52,570 --> 00:08:55,310
Here we've got clues out in the Kuiper Belt
187
00:08:55,310 --> 00:08:58,084
that indicate that's what happened.
188
00:08:58,084 --> 00:08:59,810
That's one of the exciting things
189
00:08:59,810 --> 00:09:01,630
is that we're looking at something
190
00:09:01,630 --> 00:09:03,455
that although it's far from our earth
191
00:09:03,455 --> 00:09:06,690
and far from our common experience,
192
00:09:06,690 --> 00:09:10,490
may actually be important in planetary science,
193
00:09:10,490 --> 00:09:12,568
in other solar systems as well.
194
00:09:12,568 --> 00:09:15,151
