- 00:15:38,238 --> 00:15:39,855
- 'Cause there are aliens out there that
- 334
- 00:15:39,856 --> 00:15:42,234
- probably raid planets
- and use them for food,
- 335
- 00:15:42,235 --> 00:15:44,276
- or eat the people, or make them slaves.
- 336
- 00:15:44,277 --> 00:15:46,075
- If they find it, their
- technology is probably
- 337
- 00:15:46,076 --> 00:15:47,112
- more advanced than ours.
- 338
- 00:15:47,113 --> 00:15:48,328
- They'll come here and destroy it.
- 339
- 00:15:48,329 --> 00:15:49,915
- So why would you do something like that?
- 340
- 00:15:49,916 --> 00:15:52,576
- So if somebody did find it
- they would be thinking that way
- 341
- 00:15:52,577 --> 00:15:54,830
- and they said, "Why would
- these people expose themselves
- 342
- 00:15:54,831 --> 00:15:58,457
- "to our veracious appetites
- or whatever it is.
- 343
- 00:15:58,458 --> 00:16:01,007
- "They must be very altruistic.“
- 344
- 00:16:04,380 --> 00:16:07,382
- - The chance that advanced intelligence
- 345
- 00:16:07,383 --> 00:16:10,218
- beyond us would detect "Oh, hey,
- 346
- 00:16:10,219 --> 00:16:14,556
- "there is a radiating
- body coming into our area,
- 347
- 00:16:14,557 --> 00:16:18,232
- "let's go out and find out
- what this bottle in the ocean,
- 348
- 00:16:18,233 --> 00:16:20,520
- “what message it might have."
- 349
- 00:16:20,521 --> 00:16:22,899
- Now is that a grand mystery?
- 350
- 00:16:24,442 --> 00:16:25,284
- Whoa!
- 351
- 00:16:27,153 --> 00:16:29,076
- - Well that brings up the whole question,
- 352
- 00:16:29,077 --> 00:16:31,948
- is there anybody out there?
- 353
- 00:16:31,949 --> 00:16:32,791
- Listen,
- 354
- 00:16:34,160 --> 00:16:36,703
- there are give or take
- 355
- 00:16:36,704 --> 00:16:40,040
- 200 billion stars in the Milky Way Galaxy.
- 356
- 00:16:40,041 --> 00:16:42,715
- There are about 200 billion
- galaxies in the universe.
- 357
- 00:16:42,716 --> 00:16:45,921
- Or at least in the universe we know about.
- 358
- 00:16:45,922 --> 00:16:48,215
- - It's a pretty small spacecraft
- 359
- 00:16:48,216 --> 00:16:51,092
- and it's a pretty big universe.
- 360
- 00:16:51,093 --> 00:16:53,303
- If you take a piece of sky
- 361
- 00:16:53,304 --> 00:16:56,103
- the size of a soda straw up there
- 362
- 00:16:57,558 --> 00:16:59,184
- in the Big Dipper,
- 363
- 00:16:59,185 --> 00:17:02,485
- in that tiny piece of what
- we thought was blank sky
- 364
- 00:17:02,486 --> 00:17:04,940
- was thousands of galaxies.
- 365
- 00:17:04,941 --> 00:17:06,942
- And each one of those galaxies
- 366
- 00:17:06,943 --> 00:17:09,742
- is filled with billions of stars.
- 367
- 00:17:10,780 --> 00:17:11,905
- That's just the soda straw,
- 368
- 00:17:11,906 --> 00:17:13,996
- and now you imagine the whole sky
- 369
- 00:17:13,997 --> 00:17:16,119
- filled with thousands upon thousands
- 370
- 00:17:16,120 --> 00:17:17,582
- upon thousands of galaxies.
- 371
- 00:17:17,583 --> 00:17:19,626
- Each of which is billions
- of billions of stars.
- 372
- 00:17:19,627 --> 00:17:22,876
- There's a lot of possibility out there.
- 373
- 00:17:26,462 --> 00:17:29,428
- - If you took a grain of
- sand and put it on the table,
- 374
- 00:17:29,429 --> 00:17:31,675
- and if that were the size of the Sun,
- 375
- 00:17:31,676 --> 00:17:33,891
- then the earth would
- be about an inch away.
- 376
- 00:17:33,892 --> 00:17:35,262
- And it would be microscopic.
- 377
- 00:17:35,263 --> 00:17:37,357
- And the entire solar
- system would fit on a table
- 378
- 00:17:37,358 --> 00:17:38,691
- six feet across.
- 379
- 00:17:39,559 --> 00:17:40,854
- Think about the next star.
- 380
- 00:17:40,855 --> 00:17:42,897
- The next star would be
- another grain of sand.
- 381
- 00:17:42,898 --> 00:17:44,941
- How far away from that solar system
- 382
- 00:17:44,942 --> 00:17:46,316
- would you have to put that?
- 383
- 00:17:46,317 --> 00:17:50,032
- And it turns out to be about
- seven and a half miles away.
- 384
- 00:17:50,033 --> 00:17:52,529
- It's absolutely remarkable how much space
- 385
- 00:17:52,530 --> 00:17:56,575
- there is between the stars
- and between the planets.
- 386
- 00:17:56,576 --> 00:17:59,578
- - The distances are almost unfathomable.
- 387
- 00:17:59,579 --> 00:18:01,126
- These were the fastest spacecraft
- 388
- 00:18:01,127 --> 00:18:04,499
- that had ever been built
- and launched and flown,
- 389
- 00:18:04,500 --> 00:18:05,968
- and they're travelling
- 390
- 00:18:05,969 --> 00:18:07,883
- at 10 miles per second.
- 391
- 00:18:09,797 --> 00:18:11,344
- You wouldn't even see it, right?
- 392
- 00:18:11,345 --> 00:18:12,841
- And yet, even at those
- 393
- 00:18:12,842 --> 00:18:16,553
- unfathomable by Earth standard speeds,
- 394
- 00:18:16,554 --> 00:18:18,555
- it takes decades,
- 395
- 00:18:18,556 --> 00:18:22,732
- decades to get out there
- into the outer solar system.
- 396
- 00:18:24,395 --> 00:18:25,520
- - We don't have any problem putting
- 397
- 00:18:25,521 --> 00:18:26,896
- the spacecraft through the Asteroid Belt
- 398
- 00:18:26,897 --> 00:18:28,319
- and yet at one time people think god
- 399
- 00:18:28,320 --> 00:18:30,444
- that you were gonna
- crash into an asteroid.
- 400
- 00:18:30,445 --> 00:18:34,160
- There's not very much chance
- of crashing into an asteroid.
- 401
- 00:18:34,161 --> 00:18:36,374
- It's just a lot of room out there.
- 402
- 00:18:36,375 --> 00:18:37,537
- A lot of room.
- 403
- 00:18:39,076 --> 00:18:40,544
- - If you wanna realise
- how empty our galaxy is,
- 404
- 00:18:40,545 --> 00:18:42,829
- the nearest galaxy to
- our own is Andromeda,
- 405
- 00:18:42,830 --> 00:18:44,082
- it's about two million light years away.
- 406
- 00:18:44,083 --> 00:18:46,833
- It's on a collision
- course with us right now.
- 407
- 00:18:46,834 --> 00:18:47,879
- And in five billion years
- 408
- 00:18:47,880 --> 00:18:49,967
- that galaxy's going to
- collide with our own.
- 409
- 00:18:49,968 --> 00:18:51,384
- And you might say, oh, no, oh, no,
- 410
- 00:18:51,385 --> 00:18:52,802
- but it turns out,
- 411
- 00:18:53,674 --> 00:18:56,473
- space is, even in our galaxy,
- it's mostly empty space.
- 412
- 00:18:56,474 --> 00:18:58,595
- When our two galaxies collide,
- 413
- 00:18:58,596 --> 00:19:01,190
- almost no stars will hit any other star.
- 414
- 00:19:01,191 --> 00:19:03,266
- It's mostly empty space.
- 415
- 00:19:03,267 --> 00:19:05,315
- So Voyager is likely
- to continue throughout
- 416
- 00:19:05,316 --> 00:19:07,729
- our galaxy for potentially millions
- 417
- 00:19:07,730 --> 00:19:11,858
- or maybe even billions of
- years without a collision.
- 418
- 00:19:11,859 --> 00:19:16,279
- - I have a hard time with really
- long geological timeframes.
- 419
- 00:19:16,280 --> 00:19:20,033
- You just can't get your hands around how
- 420
- 00:19:20,034 --> 00:19:22,503
- 10s of millions of years,
- what that really means.
- 421
- 00:19:22,504 --> 00:19:25,497
- And distances, astronomical distances.
- 422
- 00:19:25,498 --> 00:19:28,338
- - Yeah, once you start getting
- into the astronomical scales,
- 423
- 00:19:28,339 --> 00:19:30,210
- our solar system is pretty tiny,
- 424
- 00:19:30,211 --> 00:19:32,754
- and so this adventure of Voyager
- 425
- 00:19:32,755 --> 00:19:35,674
- which seems so remote and distant
- 426
- 00:19:35,675 --> 00:19:38,176
- for this little spacecraft to go out
- 427
- 00:19:38,177 --> 00:19:41,846
- to the giant planets is
- really just exploring
- 428
- 00:19:41,847 --> 00:19:44,849
- the tiniest closest neighbourhood
- 429
- 00:19:44,850 --> 00:19:47,694
- when you start thinking
- about cosmic scales.
- 430
- 00:19:47,695 --> 00:19:49,781
- (STATIC)
- 431
- 00:19:58,072 --> 00:19:59,119
- - The spacecraft were built
- 432
- 00:19:59,120 --> 00:20:00,786
- at the Jet Propulsion Laboratory.
- 433
- 00:20:00,787 --> 00:20:02,456
- It's a federal research centre
- 434
- 00:20:02,457 --> 00:20:06,581
- that's part of Cal-Tech
- and they build spacecraft.
- 435
- 00:20:07,832 --> 00:20:09,628
- One of the things I just admire most
- 436
- 00:20:09,629 --> 00:20:11,671
- about the engineers who built Voyager
- 437
- 00:20:11,672 --> 00:20:13,342
- is that they're always thinking about
- 438
- 00:20:13,343 --> 00:20:16,339
- the most improbable things happening.
- 439
- 00:20:16,340 --> 00:20:17,340
- You know, you want to take those people
- 440
- 00:20:17,341 --> 00:20:18,508
- on a camping trip with you
- 441
- 00:20:18,509 --> 00:20:19,556
- because they will think of.
- 442
- 00:20:19,557 --> 00:20:20,891
- Well, you've got to bring,
- 443
- 00:20:20,892 --> 00:20:22,011
- what if these bugs come out,
- 444
- 00:20:22,012 --> 00:20:23,226
- what if the tent gets flooded,
- 445
- 00:20:23,227 --> 00:20:24,893
- what if you run out of gas,
- 446
- 00:20:24,894 --> 00:20:26,891
- what if you can't start
- the fire, you know.
- 447
- 00:20:26,892 --> 00:20:28,438
- They're the what if people.
- 448
- 00:20:28,439 --> 00:20:31,527
- And when you're sending
- something out into space
- 449
- 00:20:31,528 --> 00:20:33,240
- you can't go do a service call,
- 450
- 00:20:33,241 --> 00:20:34,858
- you can't bring it back,
- 451
- 00:20:34,859 --> 00:20:36,192
- so your what if list
- 452
- 00:20:36,193 --> 00:20:38,570
- had better be like that long
- 453
- 00:20:38,571 --> 00:20:41,740
- or you're not going to be able to survive.
- 454
- 00:20:41,741 --> 00:20:43,835
- (STATIC)
- 455
- 00:20:47,371 --> 00:20:49,247
- - These projects begin
- 456
- 00:20:49,248 --> 00:20:52,459
- with a conceptualization period.
- 457
- 00:20:52,460 --> 00:20:56,880
- How feasible is it for
- us to do thus and so?
- 458
- 00:20:56,881 --> 00:21:00,304
- We didn't know what the
- spacecraft was gonna look like.
- 459
- 00:21:00,305 --> 00:21:01,974
- How do we arrange a spacecraft?
- 460
- 00:21:01,975 --> 00:21:05,513
- How do we take the communications system,
- 461
- 00:21:05,514 --> 00:21:09,350
- this large 12-foot diameter fixed antenna,
- 462
- 00:21:09,351 --> 00:21:13,730
- and arrange it relative
- to the propulsion system?
- 463
- 00:21:13,731 --> 00:21:17,110
- The spacecraft took on the
- dimension of being a child,
- 464
- 00:21:17,111 --> 00:21:20,612
- and our design teams, you know,
- were like kind of parents.
- 465
- 00:21:20,613 --> 00:21:24,365
- This was actually a nurturing process.
- 466
- 00:21:24,366 --> 00:21:25,950
- Bringing that child,
- 467
- 00:21:25,951 --> 00:21:28,124
- if you will, into reality.
- 468
- 00:21:31,957 --> 00:21:34,378
- - All spacecraft were made
- basically of the same things.
- 469
- 00:21:34,379 --> 00:21:36,716
- Silicon and aluminium, that's about it.
- 470
- 00:21:36,717 --> 00:21:38,463
- You know, that's probably 95% of it.
- 471
- 00:21:38,464 --> 00:21:40,387
- Silicon and aluminium is cheap
- 472
- 00:21:40,388 --> 00:21:44,260
- until you start making
- stuff out if it, you know.
- 473
- 00:21:44,261 --> 00:21:46,137
- - The spacecraft of
- course is quite primitive
- 474
- 00:21:46,138 --> 00:21:47,230
- by modern day standards.
- 475
- 00:21:47,231 --> 00:21:49,682
- We have three computers on board.
- 476
- 00:21:49,683 --> 00:21:51,893
- Their total memory is about,
- 477
- 00:21:51,894 --> 00:21:55,730
- 240,000 times less than
- in your smartphone.
- 478
- 00:21:55,731 --> 00:21:58,280
- - 1972 was when you had
- the technology freeze.
- 479
- 00:21:58,281 --> 00:22:00,109
- Remember we launched in 77.
- 480
- 00:22:00,110 --> 00:22:02,450
- So you freeze technology
- several years earlier,
- 481
- 00:22:02,451 --> 00:22:05,198
- and at the time the biggest
- computers in the world
- 482
- 00:22:05,199 --> 00:22:07,038
- were comparable to the kinds of things
- 483
- 00:22:07,039 --> 00:22:08,785
- we have in our pockets today.
- 484
- 00:22:08,786 --> 00:22:11,005
- And I'm not talking about a cell phone.
- 485
- 00:22:11,006 --> 00:22:13,790
- I'm actually talking about a key fob.
- 486
- 00:22:13,791 --> 00:22:15,418
- - What's wrong with 70s technology?
- 487
- 00:22:15,419 --> 00:22:20,129
- I mean, you're looking at me,
- I'm a 30s technology, right?
- 488
- 00:22:20,130 --> 00:22:21,676
- I don't apologise for the limitations
- 489
- 00:22:21,677 --> 00:22:23,972
- that we were working with at the time.
- 490
- 00:22:23,973 --> 00:22:28,888
- We milked the technology for
- what we could get from it.
- 491
- 00:22:28,889 --> 00:22:31,307
- - Voyager is about 800 kilogrammes.
- 492
- 00:22:31,308 --> 00:22:34,269
- It's main antenna is 12 feet in diameter,
- 493
- 00:22:34,270 --> 00:22:36,396
- which was the largest we could launch.
- 494
- 00:22:36,397 --> 00:22:37,364
- - There's this body,
- 495
- 00:22:37,365 --> 00:22:40,608
- this 10 sided can called the bus,
- 496
- 00:22:40,609 --> 00:22:43,488
- and that's got all the
- electronics and the computers.
- 497
- 00:22:43,489 --> 00:22:45,032

- 717
- 00:31:50,367 --> 00:31:51,960
- The spacecraft began to do things

- we're like "What is it doing?"

- 00:31:59,918 --> 00:32:01,841
- - And as the launch vehicle
- leaves the launchpad,
- 722
- 00:32:01,842 --> 00:32:04,258
- it has to roll through a certain angle
- 723
- 00:32:04,259 --> 00:32:07,096
- to get to the right
- direction for departure.
- 724
- 00:32:07,097 --> 00:32:09,764
- And the rate that it rolls
- at is a much higher rate
- 725

- than the spacecraft would ever
- normally experience flying.
- 726

- It's just riding this big rocket,

- 00:32:19,479 --> 00:32:21,230
- and that was shaking it in such a way
- 731
- 00:32:21,231 --> 00:32:23,357

- propellant was escaping
- from the launch vehicle.

- to deliver its full thrust
- 783

- because it ran out of fuel.
- 784
- 00:34:07,591 --> 00:34:09,885
- - And so the upper which was a Centaur,

- liquid, hydrogen, and oxygen stage
- 786
- 00:34:12,384 --> 00:34:14,009

- We would try to push it a
- little bit in one direction

- and it would yield a little bit,
- 1580

- and then we'd push it
- in the other direction,

- - Every time we arrived at a new planet

- 1779
- 01:18:46,350 --> 01:18:47,849
- For instance, before Voyager,
- 1780
- 01:18:47,850 --> 01:18:49,270
- all the magnetic fields
- 1781
- 01:18:49,271 --> 01:18:51,351
- have the magnetic pole near

- the rotation axis of the planet,
- 1783
- 01:18:53,229 --> 01:18:54,354
- and that was true for Jupiter,
- 1784
- 01:18:54,355 --> 01:18:55,857
- it was true for Saturn.
- 1785
- 01:18:55,858 --> 01:18:57,699
- And then we flew by Uranus and
- 1786
- 01:18:57,700 --> 01:19:00,568
- the pole was near the equator.
- 1787
- 01:19:00,569 --> 01:19:01,821
- - There's been a lot of speculation
- 1788
- 01:19:01,822 --> 01:19:04,030
- about the magnetosphere of Uranus.
- 1789
- 01:19:04,031 --> 01:19:04,953

- And the magnetosphere of Uranus
- 1792
- 01:19:08,123 --> 01:19:11,079
- is far more weird and wonderful.
- 1793
- 01:19:11,080 --> 01:19:13,748
- We found the planet tipped on it's side,
- 1794
- 01:19:13,749 --> 01:19:16,089
- but the magnetic field is then tipped
- 1795
- 01:19:16,090 --> 01:19:17,758
- relative to the spin axis.
- 1796
- 01:19:17,759 --> 01:19:21,256
- So you have this huge contortion
- 1797
- 01:19:21,257 --> 01:19:22,509
- in the magnetic field
- 1798
- 01:19:22,510 --> 01:19:25,385
- as the planet spins around.
- 1799
- 01:19:25,386 --> 01:19:26,928
- Just bizarre.
- 1800
- 01:19:26,929 --> 01:19:29,933
- Why on earth the magnetic
- field was so messed up,
- 1801
- 01:19:29,934 --> 01:19:31,149
- we had no idea.
- 1802
- 01:19:32,643 --> 01:19:36,147
- - At the time the Voyager
- Two spacecraft flew by Uranus
- 1803
- 01:19:36,148 --> 01:19:39,857
- one pole of the planet
- was pointing at the Sun.
- 1804
- 01:19:39,858 --> 01:19:41,776
- At that point in it's orbit,
- 1805
- 01:19:41,777 --> 01:19:44,320
- it's atmosphere shuts down.
- 1806
- 01:19:44,321 --> 01:19:47,791
- So the planet itself didn't look exciting.
- 1807
- 01:19:50,452 --> 01:19:53,579
- And part of that is Uranus itself
- 1808
- 01:19:53,580 --> 01:19:55,999
- holding it's secrets back.
- 1809
- 01:19:56,000 --> 01:19:59,174
- - That had to be, I guess, one of the,
- 1810
- 01:20:00,587 --> 01:20:03,965
- well, disappointments in that Uranus
- 1811
- 01:20:03,966 --> 01:20:06,139

- 01:40:52,171 --> 01:40:53,842
- and so I could pretty quickly go
- 2309
- 01:40:53,843 --> 01:40:55,307
- blemish, blemish, blemish.
- 2310
- 01:40:55,308 --> 01:40:58,093
- And I thought, "Well, where's the Earth?"
- 2311
- 01:40:58,094 --> 01:41:00,017
- How could we, you know?
- 2312
- 01:41:00,888 --> 01:41:03,723
- And then I realised there was a lot of,
- 2313
- 01:41:03,724 --> 01:41:08,103
- there were a lot of streaks
- of light in that image,
- 2314
- 01:41:08,104 --> 01:41:10,146
- and I realised finally
- 2315
- 01:41:10,147 --> 01:41:11,820
- that the Earth was sitting
- 2316
- 01:41:11,821 --> 01:41:14,285
- in one of those rays of light.
- 2317
- 01:41:15,736 --> 01:41:17,237
- You know, I just sat there for a while
- 2318
- 01:41:17,238 --> 01:41:19,406
- just kind of realising
- 2319
- 01:41:19,407 --> 01:41:22,075
- "Wow, that's the Earth, you know,
- 2320
- 01:41:22,076 --> 01:41:24,494
- “that's Voyager looking
- back at the Earth."
- 2321
- 01:41:24,495 --> 01:41:25,996
- And then once I had sort of recovered,
- 2322
- 01:41:25,997 --> 01:41:27,249
- I started calling people.
- 2323
- 01:41:27,250 --> 01:41:28,415
- I called Brad.
- 2324
- 01:41:28,416 --> 01:41:29,292
- Brad, "We got it."
- 2325
- 01:41:29,293 --> 01:41:31,209

- 2332

- oh, this didn't turn out
- 2333
- 01:41:42,597 --> 01:41:44,440
- the way we thought it
- was going to turn out,
- 2334
- 01:41:44,441 --> 01:41:47,267
- and my first impulse is to take my hand
- 2335
- 01:41:47,268 --> 01:41:49,019
- and wipe away the dust,
- 2336
- 01:41:49,020 --> 01:41:50,272
- because there was some dust on it.
- 2337
- 01:41:50,273 --> 01:41:51,944
- Well, one of the pieces of dust
- 2338
- 01:41:51,945 --> 01:41:55,734
- that I wanted to wipe away was the Earth.
- 2339

- But it didn't matter because
- in the hands of Carl,
- 2340
- 01:41:58,535 --> 01:42:01,197
- he turned it into an allegory
- 2341
