long time ago 404 00:17:32.000 --> 00:17:34.200 to plan a maintenance program. 405 00:17:34.200 --> 00:17:35.300 That is, every three years, 406 00:17:35.300 --> 00:17:37.600 we plan to go up with the Space Shuttle, 407 00:17:37.600 --> 00:17:40.900 change out instruments, change out things that broke -- 408 00:17:40.900 --> 00:17:42.700 the the gyros or something might break. 409 00:17:42.700 --> 00:17:44.700 We have gyros in stock. 410 00:17:44.700 --> 00:17:47.600 In fact, we have, in stock, in storage, 411 00:17:47.600 --> 00:17:49.900 most of the critical components on space telescope. 412 00:17:49.900 --> 00:17:52.300 So we promised that we had a way to fix it, 413 00:17:52.300 --> 00:17:55.500 and we put a new camera in with corrective optics in it 414 00:17:55.500 --> 00:17:57.100 that would cure the optical problem. 415 00:17:57.100 --> 00:17:59.200 Right, as we talk now, we are building a second 416 00:17:59.200 --> 00:18:00.700 Wide Field Camera, 417 00:18:00.700 --> 00:18:03.100 and it's not too late to put a corrective optic -- 418 00:18:03.100 --> 00:18:06.100 You can almost think of it, if you've got bad myopia, 419 00:18:06.100 --> 00:18:08.800 which you can say our telescope has now, 420 00:18:08.800 --> 00:18:10.100 and you put your glasses on, 421 00:18:10.100 --> 00:18:12.300 you can correct totally and get 20-20 vision. 422 00:18:12.300 --> 00:18:14.000 That's what we would do on the Wide Field Camera, 423 00:18:14.000 --> 00:18:15.200 the second Wide Field Camera. 424 00:18:15.200 --> 00:18:17.000 We would change one little mirror, 425 00:18:17.000 --> 00:18:18.800 relay mirror, in there, 426 00:18:18.800 --> 00:18:20.300 take out the aberration 427 00:18:20.300 --> 00:18:23.100 that the primary mirror causes -- 428 00:18:23.100 --> 00:18:24.700 That is, if it's a positive aberration, 429 00:18:24.700 --> 00:18:27.800 we put in a negative aberration and basically cancel it out. 430 00:18:27.800 --> 00:18:30.200 We feel -- The analysis is only preliminary, 431 00:18:30.200 --> 00:18:33.700 but we're pretty optimistic that we can take out 432 00:18:33.700 --> 00:18:34.800 all the aberration 433 00:18:34.800 --> 00:18:36.600 with the second Wide Field Camera 434 00:18:36.600 --> 00:18:39.600 and get us back to the original specification. 435 00:18:39.600 --> 00:18:42.200 Nobody believed us, but we promised that we'd do it 436 00:18:42.200 --> 00:18:44.500 and would do it by December of '93. 437 00:18:44.500 --> 00:18:46.200 Let me conclude by saying, 438 00:18:46.200 --> 00:18:48.800 HST was and is a difficult challenge 439 00:18:48.800 --> 00:18:51.400 for a tremendous payoff. 440 00:18:51.400 --> 00:18:53.500 Hubble became... 441 00:18:53.500 --> 00:18:56.000 It was in the press all the time with the problems. 442 00:18:56.000 --> 00:18:58.600 It was a billion-dollar mistake. 443 00:18:58.600 --> 00:19:01.100 People in the press called it a technological disaster, 444 00:19:01.100 --> 00:19:02.600 a national disgrace. 445 00:19:02.600 --> 00:19:05.700 The late-night comedy hosts were making jokes about Hubble. 446 00:19:05.700 --> 00:19:08.300 -Well, have you been reading about the problems 447 00:19:08.300 --> 00:19:09.700 of the Hubble Telescope. 448 00:19:09.700 --> 00:19:10.800 The Hubble Space Telescope? 449 00:19:10.800 --> 00:19:12.700 -The Hubble Telescope... -The Hubble Telescope... 450 00:19:12.700 --> 00:19:13.900 The Hubble Telescope. 451 00:19:13.900 --> 00:19:16.500 -See, since there's no longer a Soviet threat, 452 00:19:16.500 --> 00:19:18.200 a lot of people feel we don't need the "Star Wars" 453 00:19:18.200 --> 00:19:19.300 defense system anymore. 454 00:19:19.300 --> 00:19:20.800 Hey, I think we should keep it, you know, 455 00:19:20.800 --> 00:19:22.600 if only they shoot down that Hubble spacecraft 456 00:19:22.600 --> 00:19:24.600 and put this thing out of its misery, huh? 457 00:19:24.600 --> 00:19:25.400 [ Laughter ] 458 00:19:25.400 --> 00:19:27.300 Boy, that's what I say. 459 00:19:27.300 --> 00:19:31.100 [ Cheers and applause ] 460 00:19:31.100 --> 00:19:32.600 -The teams at NASA, 461 00:19:32.600 --> 00:19:34.800 combinations with Johnson Space Center, 462 00:19:34.800 --> 00:19:37.400 Goddard Space Flight Center, 463 00:19:37.400 --> 00:19:40.000 great astronauts, the will of the people, 464 00:19:40.000 --> 00:19:42.000 great members of Congress who supported it, 465 00:19:42.000 --> 00:19:43.400 said, "Let's fix it. 466 00:19:43.400 --> 00:19:46.300 We fixed other things, you know, and they still work. 467 00:19:46.300 --> 00:19:48.300 Old cars still run. 468 00:19:48.300 --> 00:19:50.700 Let's make Hubble the better version." 469 00:19:50.700 --> 00:19:52.400 -We were all disappointed 470 00:19:52.400 --> 00:19:55.200 but all hopeful that something might be done 471 00:19:55.200 --> 00:19:59.000 to save this spectacular space observatory, 472 00:19:59.000 --> 00:20:00.500 and, in fact, something was done. 473 00:20:00.500 --> 00:20:03.600 We had already planned to be doing servicing missions 474 00:20:03.600 --> 00:20:05.500 on Hubble over the years, 475 00:20:05.500 --> 00:20:07.300 and so the first servicing mission 476 00:20:07.300 --> 00:20:09.600 to send astronauts back to Hubble 477 00:20:09.600 --> 00:20:12.200 was designed to repair 478 00:20:12.200 --> 00:20:14.900 this problem with Hubble. 479 00:20:14.900 --> 00:20:18.300 -And this big mirror really 480 00:20:18.300 --> 00:20:20.200 was the dominant driver. 481 00:20:20.200 --> 00:20:23.400 We worked very, very hard to develop, 482 00:20:23.400 --> 00:20:26.800 first of all, you know, how distorted was it? 483 00:20:26.800 --> 00:20:29.200 How mispolished was it? 484 00:20:29.200 --> 00:20:31.900 And then to find a company 485 00:20:31.900 --> 00:20:34.100 in the United States, preferably, 486 00:20:34.100 --> 00:20:37.400 that could polish corrective lenses 487 00:20:37.400 --> 00:20:39.500 that would take care of the problem. 488 00:20:39.500 --> 00:20:42.800 Those two challenges were really immense, 489 00:20:42.800 --> 00:20:46.400 and those challenges, when they finally got solved, 490 00:20:46.400 --> 00:20:48.600 led to something that was 491 00:20:48.600 --> 00:20:51.000 an extremely important payoff 492 00:20:51.000 --> 00:20:54.000 to the US and world citizenry. 493 00:20:54.000 --> 00:20:55.700 -To fly what you test 494 00:20:55.700 --> 00:20:58.200 and test what you fly would be easier 495 00:20:58.200 --> 00:21:00.500 if the telescope were back on Earth, 496 00:21:00.500 --> 00:21:03.500 but landing and relaunching 497 00:21:03.500 --> 00:21:05.500 could contaminate the telescope 498 00:21:05.500 --> 00:21:07.500 or damage it through vibration. 499 00:21:10.400 --> 00:21:12.500 NASA couldn't test the new corrective optics 500 00:21:12.500 --> 00:21:14.400 in the actual telescope, 501 00:21:14.400 --> 00:21:16.700 so to make sure the optics will work, 502 00:21:16.700 --> 00:21:20.300 the team had to determine the condition of Hubble in space 503 00:21:20.300 --> 00:21:24.100 and replicate that on the ground. 504 00:21:24.100 --> 00:21:26.900 One independent review panel used Hubble images 505 00:21:26.900 --> 00:21:30.500 to determine the precise shape of the flawed primary mirror 506 00:21:30.500 --> 00:21:33.900 and the prescription to fix it. 507 00:21:33.900 --> 00:21:38.700 Another team had to verify that the corrective optics will work. 508 00:21:38.700 --> 00:21:41.700 Teams had to test two optical packages, 509 00:21:41.700 --> 00:21:44.700 the replacement Wide Field Planetary Camera 510 00:21:44.700 --> 00:21:46.200 and the corrective optics 511 00:21:46.200 --> 00:21:49.700 for the other instruments, called COSTAR. 512 00:21:49.700 --> 00:21:52.600 Engineers built several independent analyzers 513 00:21:52.600 --> 00:21:54.500 to test that they had replicated 514 00:21:54.500 --> 00:21:57.600 what the Hubble Telescope does to light. 515 00:21:57.600 --> 00:22:00.700 For mechanical testing, engineers built a simulator 516 00:22:00.700 --> 00:22:02.500 at Goddard Space Flight Center 517 00:22:02.500 --> 00:22:04.600 using the same precision equipment 518 00:22:04.600 --> 00:22:06.700 that built Hubble originally. 519 00:22:06.700 --> 00:22:09.200 To replicate Hubble during electrical tests 520 00:22:09.200 --> 00:22:12.000 of the corrective-optics package and the new camera, 521 00:22:12.000 --> 00:22:13.800 an electrical test facility 522 00:22:13.800 --> 00:22:15.800 was built with the same schematics 523 00:22:15.800 --> 00:22:18.100 as the original telescope. 524 00:22:18.100 --> 00:22:21.400 Hardware has been thoroughly tested on the ground. 525 00:22:21.400 --> 00:22:25.100 The Hubble servicing team is preparing for contingencies, 526 00:22:25.100 --> 00:22:27.000 but this mission is a first, 527 00:22:27.000 --> 00:22:31.000 so no one can predict everything that could happen. 528 00:22:31.000 --> 00:22:33.800 The real test will be in space. 529 00:22:33.800 --> 00:22:38.500 -Five, four, three, two, one. 530 00:22:38.500 --> 00:22:41.300 -To zero. -And we have liftoff. 531 00:22:41.300 --> 00:22:42.900 Liftoff of the Space Shuttle Endeavour 532 00:22:42.900 --> 00:22:44.600 on an ambitious mission to service 533 00:22:44.600 --> 00:22:46.400 the Hubble Space Telescope. 534 00:22:53.600 --> 00:22:56.700 -Houston, Endeavor has a firm handshake 535 00:22:56.700 --> 00:22:58.400 with Mr. Hubble's Telescope. 536 00:23:00.800 --> 00:23:04.500 -We copy that, Covey, and there are smiles galore down here. 537 00:23:06.700 --> 00:23:08.200 -They got it. -Alright! 538 00:23:08.200 --> 00:23:10.700 [ Cheers and applause ] 539 00:23:14.000 --> 00:23:16.500 -Fantastic. -I forgot my glove! 540 00:23:16.500 --> 00:23:18.100 [ Laughter ] 541 00:23:18.100 --> 00:23:20.600 -We're going to do WFPC on day two, now. 542 00:23:20.600 --> 00:23:23.800 Sudden change of plans. -That's it, change of plan. 543 00:23:23.800 --> 00:23:26.100 -No, I think if -- -...deploy the EVA. 544 00:23:26.100 --> 00:23:27.900 -I think if the arrays are straight, 545 00:23:27.900 --> 00:23:29.300 we also have an equal chance 546 00:23:29.300 --> 00:23:31.700 that there is no such thing as further aberration. 547 00:23:31.700 --> 00:23:34.600 -That's it. -The universe is aberrated, 548 00:23:34.600 --> 00:23:36.400 and we're going to be correcting for it. 549 00:23:36.400 --> 00:23:37.400 -Actually, also... 550 00:23:37.400 --> 00:23:39.700 -Okay, and then, you're seeing 551 00:23:39.700 --> 00:23:42.400 what would be the upper outboard bistem 552 00:23:42.400 --> 00:23:45.600 on the plus V2 array. 553 00:23:45.600 --> 00:23:48.900 There's a definite kink 554 00:23:48.900 --> 00:23:52.700 right at the upper edge 555 00:23:52.700 --> 00:23:55.100 of the second panel there, as you can see, 556 00:23:55.100 --> 00:23:57.600 in the max part of the bend, 557 00:23:57.600 --> 00:24:00.400 and it looks like as the bistems -- 558 00:24:00.400 --> 00:24:02.200 Of course, one is inside the other. 559 00:24:02.200 --> 00:24:06.000 It looks like the outer bistem has a kink in it, 560 00:24:06.000 --> 00:24:09.100 and it is also twisted 561 00:24:09.100 --> 00:24:13.000 approximately 90-plus degrees clockwise 562 00:24:13.000 --> 00:24:14.600 there at the kink. 563 00:24:14.600 --> 00:24:17.100 Then, it looks like it all comes back together 564 00:24:17.100 --> 00:24:20.000 within a few feet there of the kink. 565 00:24:20.000 --> 00:24:22.300 There's also -- probably hard for you all to see. 566 00:24:22.300 --> 00:24:24.300 We have to look at it with binoculars -- 567 00:24:24.300 --> 00:24:30.400 a second kink couple of feet below the obvious one that 568 00:24:30.400 --> 00:24:34.900 is on the back side there of that section of the bistem. 569 00:24:34.900 --> 00:24:36.200 It's not quite as bad, 570 00:24:36.200 --> 00:24:38.500 but it does have a little crease in it. 571 00:24:38.500 --> 00:24:39.700 -Foot restraint will be occupied 572 00:24:39.700 --> 00:24:42.900 by mission specialist Kathy Thornton. 573 00:24:42.900 --> 00:24:45.700 She will be working from the end of the mechanical arm. 574 00:24:50.500 --> 00:24:55.500 This television shows Thornton at the array, 575 00:24:55.500 --> 00:24:58.700 the array to be jettisoned. 576 00:24:58.700 --> 00:25:01.500 -Okay, KT. 577 00:25:01.500 --> 00:25:03.000 You ready? -Yeah, I'm ready. 578 00:25:03.000 --> 00:25:05.200 -Okay.

00:34:44.800 which was simply that he thought 795 00:34:44.800 --> 00:34:46.500 it was too dangerous for the astronauts 796 00:34:46.500 --> 00:34:49.200 since there was no safety net 797 00:34:49.200

just get the crew somewhere to orbit, 803 00:35:05.300 --> 00:35:07.800 we could get them to the International Space Station 804 00:35:07.800 --> 00:35:10.000 and put them aboard station until we

00:49:12.600 --> 00:49:16.100 and it took, really, a major effort 1103 00:49:16.100 --> 00:49:18.433 on the part of the astronomical community 1104 00:49:18.433 --> 00:49:20.633 to lobby Congress to

story, 1108 00:49:29.133 --> 00:49:30.600 but I think it's a good story. 1109 00:49:30.600 --> 00:49:32.000 -I'd love to hear it. 1110 00:49:32.000 --> 00:49:35.033 -Proxmire was noted 1111

00:49:46.833 and he sent a question to NASA headquarters saying, 1115 00:49:46.833 --> 00:49:49.433 "Why should the American taxpayer pay 1116 00:49:49.433 --> 00:49:52.133 for something like the Hubble?" 1117 00:49:52.133 --> 00:49:54.633 And I did a back-of-the-envelope calculation, 1118 00:49:54.633 --> 00:49:56.133 and my answer was that, 1119 00:49:56.133 --> 00:49:59.600 for the cost of a night at the movies, 1120 00:49:59.600 --> 00:50:01.300 every American taxpayer 1121 00:50:01.300 --> 00:50:05.633 would have 15 years of exciting discoveries, 1122 00:50:05.633 --> 00:50:08.633 and I may have been off by a factor of three or four, 1123 00:50:08.633 --> 00:50:11.100 depending on how you figure launch costs 1124 00:50:11.100 --> 00:50:14.033 and the servicing missions and some other things, 1125 00:50:14.033 --> 00:50:16.033 but even if it ended up being one night 1126 00:50:16.033 --> 00:50:18.100 at the movies every year, 1127 00:50:18.100 --> 00:50:20.733 I think Hubble
