1 00:00:00,000 --> 00:00:07,000 This program is not science fiction. 2 00:00:07,000 --> 00:00:18,000 It is a report on science's very real search today for the existence of life on other worlds. 3 00:00:18,000 --> 00:00:24,000 A search by microscope examining the smallest particles of matter in nature, 4 00:00:24,000 --> 00:00:32,000 by telescope viewing the largest objects in space, a probe into distant galaxies and star clusters, 5 00:00:32,000 --> 00:00:37,000 looking with the enormous eyes of the optical telescopes, 6 00:00:37,000 --> 00:00:44,000 and listening with the electronic ears of the radio telescope for signals from outer space. 7 00:00:44,000 --> 00:00:51,000 And eventually this search will be carried on by man himself through interplanetary travel. 8 00:00:55,000 --> 00:01:04,000 The elements that exist here on Earth and the chemistry of our world are the same as on the most distant star. 9 00:01:04,000 --> 00:01:13,000 If the atom, one of the smallest particles of matter, and the galaxy, the largest mass in the visible universe, 10 00:01:13,000 --> 00:01:22,000 are governed by the same physical laws, then life might well have evolved from the hydrogen atom in space. 11 00:01:22,000 --> 00:01:29,000 It has continued to the development of the human brain and may have repeated a similar process 12 00:01:29,000 --> 00:01:35,000 unnumbered times in the hundreds of billions of worlds abounding in the cosmos, 13 00:01:35,000 --> 00:01:42,000 making the probability great that intelligent creatures beside Earthman, people the universe. 14 00:01:42,000 --> 00:02:01,000 On just the beginning of this search for life on other planets, the American taxpayer is spending $2 billion in probes of Mars alone. 15 00:02:01,000 --> 00:02:08,000 Nobel Prize winning scientist Dr. Harold Urie says of the cost of the space program, 16 00:02:08,000 --> 00:02:18,000 some people say that we can't afford this space program, but I say the Greeks couldn't afford the popular, 17 00:02:18,000 --> 00:02:27,000 and the Egyptians couldn't afford the pyramids, and middle ages couldn't afford the great cathedral of Europe. 18 00:02:27,000 --> 00:02:35,000 You could have always spent this money, as they say, for something else, but you know we can't afford this space program. 19 00:02:35,000 --> 00:02:41,000 They wouldn't have proved that life existed on Mars or ever did exist on Mars. 20 00:02:41,000 --> 00:02:47,000 In my opinion it would be one of the most horrendous discoveries of this century. 21 00:03:05,000 --> 00:03:12,000 We are not alone. 22 00:03:12,000 --> 00:03:20,000 Is brought to you by T. F. Goodrich, the name that sells quality, 23 00:03:20,000 --> 00:03:31,000 entire, chemical, plastic, footwear, product, or whole industry and aviation. 24 00:03:31,000 --> 00:03:36,000 T. F. Goodrich. 25 00:03:36,000 --> 00:03:52,000 Phyllis! Phyllis! Isn't this the day you were going to buy new tires? 26 00:03:52,000 --> 00:04:01,000 Phyllis! 27 00:04:01,000 --> 00:04:06,000 Why is this tire buying day always seems like the morning after? 28 00:04:06,000 --> 00:04:12,000 All the waiting around, the endless confusion about the right tire to buy, 29 00:04:12,000 --> 00:04:17,000 as the biggest blow of all, the money it's got. 30 00:04:17,000 --> 00:04:25,000 Now, the F. Goodrich doesn't give away free tires, but if tire buying day drags you down, 31 00:04:25,000 --> 00:04:29,000 we'll wake you up with a brand new way of doing business. 32 00:04:29,000 --> 00:04:34,000 No confusing tire talk, just straight talk. 33 00:04:34,000 --> 00:04:40,000 We've got nothing apart from these, except this, a special tire value calculator 34 00:04:40,000 --> 00:04:44,000 that'll find you the right tire at the right price. 35 00:04:44,000 --> 00:04:50,000 The lowest price, the F. Goodrich's tire for the way you drive. 36 00:04:50,000 --> 00:04:54,000 Well, you may be so happy at the money, F. Goodrich, you can take it. 37 00:04:54,000 --> 00:04:59,000 You want to bring the money to life. 38 00:04:59,000 --> 00:05:03,000 The F. Goodrich. 39 00:05:03,000 --> 00:05:07,000 The straight talk tire people. 40 00:05:07,000 --> 00:05:11,000 Here now, your narrator, Edward P. Morgan. 41 00:05:11,000 --> 00:05:18,000 The fixed stars in our firmament have, through the ages, given man a feeling of security. 42 00:05:18,000 --> 00:05:24,000 We have always wanted to believe that we have our feet firmly planted on a solid earth 43 00:05:24,000 --> 00:05:27,000 with a protective heaven above. 44 00:05:27,000 --> 00:05:32,000 But science has continually whittled away at this idea. 45 00:05:32,000 --> 00:05:36,000 For some time, we have known that our earth, in reality, 46 00:05:36,000 --> 00:05:41,000 is only a changing ball of rock and soil, water and air, 47 00:05:41,000 --> 00:05:48,000 held together by a tenuous gravity, spinning and whirling in space around our sun. 48 00:05:48,000 --> 00:05:52,000 And even as a planet, we are not very special, 49 00:05:52,000 --> 00:05:57,000 being only one of nine in orbit around the mother sun. 50 00:05:57,000 --> 00:06:03,000 Our sun itself, a star and only a small middle-aged one as stars go, 51 00:06:03,000 --> 00:06:08,000 is a kind of lost child on the outskirts of its galaxy, 52 00:06:08,000 --> 00:06:13,000 which we can see in the sky as the Milky Way. 53 00:06:13,000 --> 00:06:18,000 It is only one of hundreds of billions of stars in our galaxy, 54 00:06:18,000 --> 00:06:22,000 which is only one of hundreds of billions of galaxies, 55 00:06:22,000 --> 00:06:26,000 all of which are in constant motion. 56 00:06:26,000 --> 00:06:32,000 If we are not unchanging in space, neither are we eternal in time. 57 00:06:32,000 --> 00:06:39,000 Our sun, five billion years old, will, in another five billion years or so, 58 00:06:39,000 --> 00:06:45,000 burn itself out and in doing so, expand and absorb all its planets 59 00:06:45,000 --> 00:06:49,000 as countless other stars have done before. 60 00:06:49,000 --> 00:06:54,000 Our sun's only real distinction that we know of thus far 61 00:06:54,000 --> 00:06:58,000 is that it has people whirling around it. 62 00:06:58,000 --> 00:07:03,000 The question is, might this have happened elsewhere in the universe 63 00:07:03,000 --> 00:07:07,000 or are we alone? 64 00:07:07,000 --> 00:07:11,000 It was recently discovered that stars and gases in space 65 00:07:11,000 --> 00:07:18,000 emit natural radio waves, which can be picked up and amplified by radio telescopes. 66 00:07:18,000 --> 00:07:23,000 The John Groll Bank radio telescope in England, 67 00:07:23,000 --> 00:07:27,000 the Green Bank radio telescope in West Virginia, 68 00:07:27,000 --> 00:07:34,000 and this one at RSC Bow in Puerto Rico, can be called man's largest ears. 69 00:07:34,000 --> 00:07:38,000 The bowl of the telescope, a thousand feet across, 70 00:07:38,000 --> 00:07:43,000 made of half-inch wire mesh, acts as a reflector, 71 00:07:43,000 --> 00:07:49,000 able to focus even extremely weak radio signals from space. 72 00:07:49,000 --> 00:07:52,000 In searching for life on other worlds, 73 00:07:52,000 --> 00:07:56,000 the theory is that intelligent civilizations in the universe 74 00:07:56,000 --> 00:08:02,000 would use natural radio frequencies as a means of communicating with one another. 75 00:08:02,000 --> 00:08:06,000 By listening to signals from interstellar space, 76 00:08:06,000 --> 00:08:12,000 intelligent codes could be distinguished from the patterns of natural radio waves. 77 00:08:12,000 --> 00:08:19,000 Radio astronomer of Cornell University and director of the RSC Bow Ionospheric Observatory, 78 00:08:19,000 --> 00:08:23,000 Dr. Frank Drake, conducted Project OSMA, 79 00:08:23,000 --> 00:08:29,000 the first search for intelligent life in space by radio telescope. 80 00:08:29,000 --> 00:08:35,000 Ten years ago it was suggested by Professors Morrison and Keconi at Cornell 81 00:08:35,000 --> 00:08:41,000 that there might be other civilizations in space attempting to send us messages. 82 00:08:41,000 --> 00:08:46,000 We use very sensitive and ingenious detecting devices 83 00:08:46,000 --> 00:08:52,000 to search for intelligent signals amongst static which comes to us from the interstellar space. 84 00:08:52,000 --> 00:08:57,000 By 1960 we made a short search for such signals. 85 00:08:57,000 --> 00:09:01,000 With existing telescopes such as the 85-foot telescope at Greenbank, 86 00:09:01,000 --> 00:09:05,000 using the 21-centimeter line frequency, 87 00:09:05,000 --> 00:09:09,000 there was time in fact to look at only two stars, 88 00:09:09,000 --> 00:09:13,000 the ones we picked of course were the two nearest stars which are like the sun. 89 00:09:13,000 --> 00:09:18,000 The star is Tarsidi and the constellation of Cetus-Bewale 90 00:09:18,000 --> 00:09:22,000 and epsilon-arythmi in the constellation of Arithmus. 91 00:09:22,000 --> 00:09:26,000 We found no evidence for extraterrestrial intelligence signals. 92 00:09:26,000 --> 00:09:30,000 But now we must realize that this was an extremely limited search 93 00:09:30,000 --> 00:09:34,000 and the fact that we found nothing should not discourage us 94 00:09:34,000 --> 00:09:38,000 or cause us to think that any future search is going to fail. 95 00:09:38,000 --> 00:09:42,000 One can estimate that a search which has a good chance of succeeding 96 00:09:42,000 --> 00:09:44,000 will take perhaps 30 years. 97 00:09:44,000 --> 00:09:48,000 But if one is going to make a realistic search, this is what is required 98 00:09:48,000 --> 00:09:54,000 and anything less than this is really not with the effort because the chance of success is so small. 99 00:09:54,000 --> 00:09:59,000 Surely the results of the construction of extraterrestrial signals 100 00:09:59,000 --> 00:10:03,000 are going to be one of the most exciting things that ever happened. 101 00:10:04,000 --> 00:10:07,000 While some scientists in the discipline of astronomy 102 00:10:07,000 --> 00:10:11,000 press the search for intelligent life in the distant stellar regions 103 00:10:11,000 --> 00:10:18,000 beyond our solar system with the big ears and eyes of the radio and optical telescopes, 104 00:10:18,000 --> 00:10:22,000 some, perhaps more down-to-earth investigators, 105 00:10:22,000 --> 00:10:27,000 feel they would be making an historic discovery by a less ambitious find. 106 00:10:27,000 --> 00:10:31,000 These men are called exobiologists. 107 00:10:31,000 --> 00:10:35,000 They are looking for microbiologic forms of life, 108 00:10:35,000 --> 00:10:40,000 lesser than intelligent man, and perhaps higher than the lowly virus, 109 00:10:40,000 --> 00:10:48,000 something between the organic molecule and the bacteria that might have evolved outside the Earth. 110 00:10:48,000 --> 00:10:54,000 The most likely candidates for such a search are the planets Mars and Venus, 111 00:10:54,000 --> 00:10:58,000 Earth's nearest neighbors in the solar system. 112 00:10:58,000 --> 00:11:06,000 The Mariner spacecraft has been our principal vehicle for unmanned planetary exploration. 113 00:11:06,000 --> 00:11:11,000 The planetary program is carried out by the Jet Propulsion Laboratory, 114 00:11:11,000 --> 00:11:14,000 operated by the California Institute of Technology, 115 00:11:14,000 --> 00:11:18,000 for the National Aeronautics and Space Administration. 116 00:11:18,000 --> 00:11:22,000 Dr. William H. Pickering is the director. 117 00:11:22,000 --> 00:11:26,000 Mars and Venus were both of the closest planets to the Earth. 118 00:11:26,000 --> 00:11:30,000 In some ways we know more about Mars than we do about Venus, 119 00:11:30,000 --> 00:11:34,000 because Venus is always covered with clouds. 120 00:11:34,000 --> 00:11:38,000 We do not believe we have ever seen down to the surface of Venus. 121 00:11:38,000 --> 00:11:41,000 That is with the telescope from the Earth. 122 00:11:41,000 --> 00:11:47,000 Whereas in the case of Mars, we usually see the surface of Mars. 123 00:11:47,000 --> 00:11:53,000 And Mars, on the other hand, is a planet which astronomers for many years have compared with the Earth. 124 00:11:53,000 --> 00:11:56,000 The size is a little smaller than the Earth. 125 00:11:56,000 --> 00:12:00,000 It happens that the day on Mars is almost exactly the same length as the day on the Earth. 126 00:12:00,000 --> 00:12:04,000 The year is about twice as long as the year on the Earth. 127 00:12:04,000 --> 00:12:08,000 The seasons change in the same manner that they do on the Earth. 128 00:12:08,000 --> 00:12:11,000 In other words, the spin axis of Mars is tilted, 129 00:12:11,000 --> 00:12:14,000 not the same way that the axis of the Earth is tilted. 130 00:12:14,000 --> 00:12:22,000 All of this has led astronomers to compare Mars with the Earth in many ways. 131 00:12:22,000 --> 00:12:27,000 And of course one comparison which one must always make is 132 00:12:27,000 --> 00:12:33,000 what about life? Is Mars a suitable planet for life as we know it? 133 00:12:33,000 --> 00:12:35,000 It is feasible. 134 00:12:35,000 --> 00:12:39,000 And what we know about life on Earth, life could exist on Mars. 135 00:12:39,000 --> 00:12:46,000 Dr. Richard S. Young, Chief of the Exobiology Division of NASA's Ames Research Center. 136 00:12:46,000 --> 00:12:54,000 Life on Earth probably arose as a result of a very natural sequence of events. 137 00:12:54,000 --> 00:13:00,000 We think we know what the primitive atmosphere of the Earth was like before there was any life on the Earth. 138 00:13:00,000 --> 00:13:06,000 We think we know what types of energies were available on the primitive Earth before there was any life on Earth. 139 00:13:06,000 --> 00:13:11,000 The biological evolution took over and the atmosphere was changed rather drastically 140 00:13:11,000 --> 00:13:14,000 until we have the sort of atmosphere we have on the Earth today 141 00:13:14,000 --> 00:13:18,000 and we have the tremendous diversity of life that we have today. 142 00:13:18,000 --> 00:13:24,000 A subsequent result over the next, say, 3 billion years of biological evolution. 143 00:13:24,000 --> 00:13:29,000 In fact, then, just about any primitive planet during its early history 144 00:13:29,000 --> 00:13:33,000 should have undergone a similar sequence of events. 145 00:13:33,000 --> 00:13:37,000 They were formed obeying the same laws of physics and chemistry. 146 00:13:37,000 --> 00:13:40,000 They should have had the same type of primitive atmosphere. 147 00:13:40,000 --> 00:13:44,000 They probably underwent chemical evolution much the same way the Earth did. 148 00:13:44,000 --> 00:13:47,000 Now, what we need is proof of that. 149 00:13:47,000 --> 00:13:51,000 If we can find life on one planet, say Mars, 150 00:13:51,000 --> 00:13:56,000 then it is very probable that elsewhere within our own galaxy 151 00:13:56,000 --> 00:14:02,000 there must certainly be planets comparable to Earth with life forms comparable to Earth. 152 00:14:05,000 --> 00:14:10,000 The optical telescope has been the principal tool of astronomers 153 00:14:10,000 --> 00:14:15,000 for studying the stars and the planets from the days of Galileo centuries ago. 154 00:14:15,000 --> 00:14:21,000 The 200-inch mirror in the Palomar Observatory Telescope in California 155 00:14:21,000 --> 00:14:24,000 can be called man's largest eye. 156 00:14:24,000 --> 00:14:29,000 It can bring into view the farthest observable objects in the universe, 157 00:14:29,000 --> 00:14:34,000 called quasars, points of light believed to be billions of light years away 158 00:14:34,000 --> 00:14:38,000 and moving away from us at incredible speeds. 159 00:14:38,000 --> 00:14:45,000 Another kind of telescope is the 26-inch refractor or direct-view telescope 160 00:14:45,000 --> 00:14:50,000 like this one at the United States Naval Observatory in Washington, D.C. 161 00:14:51,000 --> 00:14:58,000 To find planets comparable to Earth revolving around stars comparable to our sun, 162 00:14:58,000 --> 00:15:02,000 Dr. Kai Strand, scientific director of the Observatory 163 00:15:02,000 --> 00:15:08,000 and his former colleague Dr. Peter Vandekamp of Swarthmore College 164 00:15:08,000 --> 00:15:11,000 used a telescope of this type. 165 00:15:11,000 --> 00:15:16,000 They wanted to verify the argument that planets are abundant in the universe. 166 00:15:16,000 --> 00:15:23,000 In 1963, Vandekamp announced the discovery of a planet orbiting a neighboring star, 167 00:15:23,000 --> 00:15:28,000 the first planet ever to be detected beyond our solar system, 168 00:15:28,000 --> 00:15:32,000 although it has never been directly seen. 169 00:15:32,000 --> 00:15:34,000 What does that mean by seen? 170 00:15:34,000 --> 00:15:40,000 Harvard astronomer Carl Sagan explains how the existence of this planet was deduced. 171 00:15:40,000 --> 00:15:47,000 The second nearest star system after the sound is called Barnard's star 172 00:15:47,000 --> 00:15:50,000 named after an American astronomer, E.E. Barnard. 173 00:15:50,000 --> 00:15:58,000 And the motion of this star, of course, the star is not a more or less uniform line 174 00:15:58,000 --> 00:16:03,000 on the background stars as you might expect when it oscillates. 175 00:16:03,000 --> 00:16:08,000 And the weirdly-path is due to the presence of a dark companion. 176 00:16:08,000 --> 00:16:13,000 We don't see the dark companion, but we can quite reliably induce its presence 177 00:16:13,000 --> 00:16:17,000 from the moving motion of this star. 178 00:16:17,000 --> 00:16:20,000 Let's suppose this is Jupiter and this is the sun, 179 00:16:20,000 --> 00:16:24,000 and the two of them are moving, of course, to a space together. 180 00:16:24,000 --> 00:16:27,000 However, Jupiter is also going around the sun. 181 00:16:27,000 --> 00:16:32,000 Jupiter is on this side of the sun, its gravitational attraction moves a little bit that way. 182 00:16:32,000 --> 00:16:37,000 What is on the other side of the sun? It moves a little bit that way. 183 00:16:37,000 --> 00:16:44,000 And so, as the sun goes from space, it has, in addition to its ordinary motion that way, 184 00:16:44,000 --> 00:16:50,000 it has a fan up and down wiggle due to the motion of the invisible Jupiter. 185 00:16:50,000 --> 00:16:54,000 And so the wiggle tells you the presence of Jupiter, and not only that, 186 00:16:54,000 --> 00:16:59,000 it tells you its mass and it tells you how far away it is. 187 00:16:59,000 --> 00:17:05,000 If the existence of planetary systems around stars other than our own sun 188 00:17:05,000 --> 00:17:09,000 is a scientifically established fact, and if, as we know, 189 00:17:09,000 --> 00:17:14,000 there are hundreds of billions of such suns in our own galaxy alone, 190 00:17:14,000 --> 00:17:20,000 some leading astronomers dedicated to the idea that life does exist elsewhere 191 00:17:20,000 --> 00:17:27,000 have calculated the possible number of stars whose energy might support life. 192 00:17:27,000 --> 00:17:33,000 Astronomer Dr. Harlow Shatley, director emeritus of Harvard College Observatory, 193 00:17:33,000 --> 00:17:39,000 who first measured the size of our galaxy, now retired to his New Hampshire farm, 194 00:17:39,000 --> 00:17:46,000 discusses cosmic matters with two young friends, Georgia and Emily Huffley. 195 00:17:46,000 --> 00:17:48,000 Hi, Star-Lady. 196 00:17:48,000 --> 00:17:51,000 The whole sky, how many stars are there? 197 00:17:51,000 --> 00:17:58,000 You can see a thousand stars, and you go out some here, dark night, a thousand stars, 198 00:17:58,000 --> 00:18:01,000 make a die star as we call them, but if we put a telescope into action, 199 00:18:01,000 --> 00:18:05,000 we get deeper and deeper into space, and the further out we go, Emily, 200 00:18:05,000 --> 00:18:07,000 the more stars we find. 201 00:18:07,000 --> 00:18:10,000 And so now, how many stars are there? 202 00:18:10,000 --> 00:18:17,000 Well, I've measured these galaxies and these stars, and these shooting stars and so forth, 203 00:18:17,000 --> 00:18:19,000 and you know what I find out? 204 00:18:19,000 --> 00:18:22,000 That there are just billions of these galaxies. 205 00:18:22,000 --> 00:18:25,000 Now, billions, you know what the billion is, it's a thousand billion. 206 00:18:25,000 --> 00:18:31,000 Well, there are more than a thousand million of these galaxies in the sky, 207 00:18:31,000 --> 00:18:36,000 and each galaxy has more than ten thousand million stars, and so is just lots of stars in the sky. 208 00:18:36,000 --> 00:18:39,000 I'll give you the number of future I remember. 209 00:18:39,000 --> 00:18:44,000 The number of stars is more than a hundred thousand million billion. 210 00:18:44,000 --> 00:18:48,000 Stars are not for everybody, see if you want some stars, you have a lot of them. 211 00:18:48,000 --> 00:18:51,000 I don't know where is anybody living on those stars. 212 00:18:51,000 --> 00:18:55,000 I'm not on the stars, you can't live on the stars, you can't live on the sun. 213 00:18:55,000 --> 00:18:57,000 Oh, a planet. 214 00:18:57,000 --> 00:18:59,000 Yes, it's too hot, that's it. 215 00:18:59,000 --> 00:19:01,000 That's too hot. 216 00:19:01,000 --> 00:19:06,000 But planets, yes you can live on it, that is here on this planet we can. 217 00:19:06,000 --> 00:19:10,000 Do you know where we have the planet, where we might have to fly a life? 218 00:19:10,000 --> 00:19:13,000 No, you have to hear Mars. 219 00:19:13,000 --> 00:19:16,000 The planet Mars, that might have some life on it. 220 00:19:16,000 --> 00:19:20,000 It might have, we'll have to give more and more observations, and then we'll come out. 221 00:19:20,000 --> 00:19:28,000 My guess is that there are more than a hundred million planets that have living things on them. 222 00:19:28,000 --> 00:19:32,000 By living, I mean like trees and grass and people of that kind. 223 00:19:32,000 --> 00:19:36,000 I think at least that many, and I'm a very conservative person. 224 00:19:36,000 --> 00:19:41,000 Like how these wheelshapes are known, it's flattened like this, but has a big center, 225 00:19:41,000 --> 00:19:45,000 and it has that hundred thousand million stars, it's got it all the way through it. 226 00:19:45,000 --> 00:19:49,000 It's rotating too, you've measured that, it's turning around. 227 00:19:49,000 --> 00:19:51,000 It's a long time it's turning around. 228 00:19:51,000 --> 00:19:59,000 I'll tell you how long, it'll take about two hundred million years to make one complete turn around in our galaxy. 229 00:19:59,000 --> 00:20:01,000 From where we are. 230 00:20:01,000 --> 00:20:03,000 Any other questions? 231 00:20:03,000 --> 00:20:05,000 How are the planets formed? 232 00:20:05,000 --> 00:20:07,000 Oh, how are planets formed? 233 00:20:07,000 --> 00:20:09,000 Oh, that's a hard job. 234 00:20:09,000 --> 00:20:18,000 But I'll tell you, we think that once before, long ago, long, long ago there's a whole lot of dust and gas in space. 235 00:20:18,000 --> 00:20:23,000 And it contracted, it came together, and it's harder and harder, it came together, 236 00:20:23,000 --> 00:20:28,000 and it left off some chunks that went floating around, and those were the things that became planets. 237 00:20:28,000 --> 00:20:34,000 So we had the Sun, you see, built out of a shrinking nebula, we call it. 238 00:20:34,000 --> 00:20:39,000 Other than shrinking nebula is Sun, and it threw off these particular little chunks, 239 00:20:39,000 --> 00:20:45,000 little compared with the Sun, and those little chunks developed into being the planets. 240 00:20:45,000 --> 00:20:55,000 So we have the Earth, once was gaseous nebulosity, we call it, it once was gas, and it shrunk down, and now it's just hard. 241 00:20:55,000 --> 00:20:57,000 See how hard this is? 242 00:20:57,000 --> 00:20:59,000 We are not alone. 243 00:20:59,000 --> 00:21:05,000 We'll continue with science's search for life on Mars, and the exploration of life's origin on Earth, 244 00:21:05,000 --> 00:21:09,000 after this message from the B.F. Goodrich Company. 245 00:21:10,000 --> 00:21:29,000 If you have little feet, big feet, old feet, cold feet, casting feet, blasting feet, 246 00:21:30,000 --> 00:21:41,000 plastic feet, roll plastic feet, splashing feet, B.F. Goodrich is always coming up with innovations in footwear, 247 00:21:41,000 --> 00:21:47,000 innovations like the posture foundation wedge we build into the heels of sneakers, 248 00:21:47,000 --> 00:21:53,000 to take the strain off foot and leg muscles, innovations in cold weather boots, 249 00:21:53,000 --> 00:22:01,000 insulated to keep feet warm even at 25 below zero, innovations to protect women's clothes, 250 00:22:01,000 --> 00:22:05,000 and all kinds of fashion footwear. 251 00:22:05,000 --> 00:22:07,000 We make just the good fun of it. 252 00:22:23,000 --> 00:22:41,000 All from B.F. Goodrich, a company known for being pretty fat on its feet. 253 00:22:41,000 --> 00:22:46,000 You're again your narrator, Edward P. Morgan. 254 00:22:46,000 --> 00:22:55,000 If you were riding the nose cone of a rocket to the moon, this is what you would see as you approached the lunar surface for a landing. 255 00:22:55,000 --> 00:23:07,000 These pictures were made by television cameras in Ranger 9, the unmanned American picture taking expedition to the moon in March of 1965. 256 00:23:07,000 --> 00:23:15,000 Since then, thousands of spectacular close-up pictures of the moon's surface have been returned by Surveyor 1, 257 00:23:15,000 --> 00:23:20,000 which soft landed on the moon in June of 1966. 258 00:23:20,000 --> 00:23:29,000 Pictures from the probe of lunar orbiter in August of 1966 showed our planet as seen from the vicinity of the moon. 259 00:23:30,000 --> 00:23:37,000 This representation of the lunar landscape shows us what a man might see from the moon, 260 00:23:37,000 --> 00:23:43,000 a bright sun in a sky black as night due to the lack of light diffusion by an atmosphere, 261 00:23:43,000 --> 00:23:51,000 and the earth visible in the lunar night hanging in its black sky like an oversized moon itself. 262 00:23:51,000 --> 00:23:57,000 Surveyor 1 and lunar orbiter returned much valuable information, 263 00:23:57,000 --> 00:24:07,000 and they have also shown us what we have known the moon to be, a body without atmosphere, without water, without life. 264 00:24:07,000 --> 00:24:15,000 Not unlike the moon in some aspects is Earth's neighbor in the solar system, the planet Mars. 265 00:24:15,000 --> 00:24:24,000 When in July of 1965, the Mariner 4 spacecraft completed a successful Mars flyby 266 00:24:24,000 --> 00:24:34,000 after a journey of 8 months and 325 million miles passing within 6,500 miles of the planet, 267 00:24:34,000 --> 00:24:44,000 21 pictures of the Martian surface were returned to Earth, including one of the most remarkable scientific photographs of this age. 268 00:24:44,000 --> 00:24:58,000 Mariner's 11th picture of Mars. Many scientists felt that this picture settled once and for all the century-long controversy over Martian canals. 269 00:24:58,000 --> 00:25:11,000 In 1877, the Italian astronomer Giovanni Scaparelli claimed to have seen canals which he thought could be evidence for intelligent life on Mars. 270 00:25:11,000 --> 00:25:19,000 As late as 1908, the American astronomer Percival Lowell confirmed the sightings. 271 00:25:19,000 --> 00:25:28,000 The spacecraft Mariner was too far away in its flyby to be able to show decisively what exists on the Martian surface, 272 00:25:28,000 --> 00:25:37,000 but most scientists agree that if life does exist there, it will not be intelligent but of a very low order. 273 00:25:37,000 --> 00:25:44,000 Of course, the earliest astronomers saw canals and saw a lot of other things, but Dr. Richard Deon was Ames Research Center. 274 00:25:44,000 --> 00:25:51,000 We no longer think canals really exist on Mars. We think they're primarily optical illusions, 275 00:25:51,000 --> 00:26:01,000 and they're not something that the Martians constructed to transport water from the pole to the equator and keep the desert wet and all that sort of thing. 276 00:26:01,000 --> 00:26:09,000 Mars has, although it's a harsh environment by biological standards, Mars has an atmosphere, 277 00:26:09,000 --> 00:26:14,000 but it has a very rare atmosphere. The smaller planet has a lower gravitational field, 278 00:26:14,000 --> 00:26:24,000 and its atmosphere is probably something like 100 or perhaps even closer to 1,000 of the total pressure on the surface of the Earth. 279 00:26:24,000 --> 00:26:32,000 It also contains water. Life can't exist without water, but the fact that Mars has water is terribly significant. 280 00:26:32,000 --> 00:26:38,000 Now, unfortunately, from a biological point of view, the amount of water in the atmosphere of Mars is very slight. 281 00:26:38,000 --> 00:26:44,000 It's about 1 in 1,000 for the amount that one would detect in the Earth's atmosphere with a similar observation. 282 00:26:44,000 --> 00:26:50,000 There are other features of Mars that we're reasonably familiar with. Astronomers have been observing it for something approaching 100 years now, 283 00:26:50,000 --> 00:26:58,000 and they've known that there are light areas and there are dark areas. The dark areas are assumed to be, at least by the early astronomers, 284 00:26:58,000 --> 00:27:04,000 were assumed to be vegetation. The light areas were assumed to be desert. 285 00:27:04,000 --> 00:27:09,000 There are also pole caps on Mars, which have been shown to be water. 286 00:27:09,000 --> 00:27:17,000 However, although they're pretty extensive, the total amount of water in these pole caps is very slight, probably nothing more than a layer of frost. 287 00:27:18,000 --> 00:27:24,000 However, these pole caps do recede seasonally. In the spring, the pole cap recedes. 288 00:27:24,000 --> 00:27:34,000 At the same time, the pole cap is receding or disappearing, the dark areas are getting darker, implying, at least to the early astronomers, 289 00:27:34,000 --> 00:27:45,000 that, well, water is becoming available now from the pole caps and the vegetation in the dark areas is literally inhaling the water and disforshing during the spring. 290 00:27:45,000 --> 00:27:54,000 We really simply don't know enough about the intimate detail of the surface of Mars to critically analyze any of these visual phenomena, 291 00:27:54,000 --> 00:27:57,000 or we can do a speculate about them. 292 00:27:57,000 --> 00:28:05,000 And so far, the best of our speculations has failed to demonstrate that life on Mars must be ruled out. 293 00:28:05,000 --> 00:28:14,000 In fact, the best of what we know still leaves well within the range of possibility the idea that life may well exist on Mars, 294 00:28:14,000 --> 00:28:18,000 and would be well worth the search, if you will. 295 00:28:18,000 --> 00:28:24,000 I feel that in the 6th or extra direction, a live of the three approaches, one, first to the one that you named, 296 00:28:24,000 --> 00:28:29,000 to go to Mars and see whether there's life there. 297 00:28:29,000 --> 00:28:37,000 The other one, which Frank Drake has sometimes tried out, listening to radio communication from other species. 298 00:28:37,000 --> 00:28:43,000 The third one is the one that we are working on here, retracing the part by which life appeared. 299 00:28:44,000 --> 00:28:52,000 Dr. Cyril Panam Varuma, chemist at Ames Research Center, is searching for answers to extraterrestrial life 300 00:28:52,000 --> 00:28:56,000 by studying the chemical evolution of life on Earth. 301 00:28:56,000 --> 00:29:04,000 From the information we have today, we know that the Earth is one and a half billion years old. 302 00:29:04,000 --> 00:29:07,000 Let me put that down as one of our starting points. 303 00:29:08,000 --> 00:29:13,000 4.7 billion years is the exact date given. 304 00:29:13,000 --> 00:29:22,000 Life as we know it, or the first ever time in life, in the fossil record, is about 3 billion. 305 00:29:22,000 --> 00:29:27,000 Now, biology or the Darwinian theory takes over from here. 306 00:29:27,000 --> 00:29:32,000 You'll find the life evolving into a variety of organisms. 307 00:29:33,000 --> 00:29:44,000 We know that mammals are around 160 million, and then so on, become the evolution of man. 308 00:29:44,000 --> 00:29:49,000 Finally, what went on before this? 309 00:29:49,000 --> 00:29:57,000 From the time the Earth was formed, or even further back, from the time the solar system was formed? 310 00:29:58,000 --> 00:30:02,000 This can be described as the chemical evolution. 311 00:30:02,000 --> 00:30:07,000 We know that the solar system is about 5 billion. 312 00:30:07,000 --> 00:30:17,000 And then, if you go backwards in time, you'll come to the origin of the universe, which is greater than 10 billion. 313 00:30:17,000 --> 00:30:23,000 That's 13, so that's 20, but we know that it's definitely more than 10 billion years. 314 00:30:23,000 --> 00:30:27,000 Now, we have some starting points to go on. 315 00:30:27,000 --> 00:30:31,000 We know that 90% of the universe is hydrogen. 316 00:30:31,000 --> 00:30:38,000 So, the hydrogen, then, by the years of reaction, that you're in the birth of a star, 317 00:30:38,000 --> 00:30:44,000 gave rise to the other element of the periodic table, carbon, nitrogen, oxygen, and so on. 318 00:30:44,000 --> 00:30:50,000 In other words, you would have thermonuclear reactions taking place within a star. 319 00:30:51,000 --> 00:30:58,000 Well, the idea of chemical evolution, then, is the gradual evolution of hydrogen, 320 00:30:58,000 --> 00:31:04,000 the initial matter of the universe, to fuel the elements of the periodic table, 321 00:31:04,000 --> 00:31:13,000 to fuel the constituents of the early Earth atmosphere, the methane, ammonia, and water. 322 00:31:13,000 --> 00:31:18,000 Simple chemistry tells us that the carbon will be in the normal methane. 323 00:31:18,000 --> 00:31:24,000 The nitrogen will be in the form of ammonia, and the oxygen will be in the form of water. 324 00:31:24,000 --> 00:31:30,000 So, the early atmosphere of the planet would have been made up of methane, ammonia, and water. 325 00:31:30,000 --> 00:31:38,000 From here on, we visualize what happened, the atmosphere being asked to be formed by lightning, 326 00:31:38,000 --> 00:31:44,000 or water life from the sun, or heat, producing organic molecules, 327 00:31:44,000 --> 00:31:49,000 until the early oceans became something like a prime audio tube. 328 00:31:49,000 --> 00:31:54,000 So, from this primitive atmosphere, we are hoping to go to this stage 329 00:31:54,000 --> 00:32:00,000 when the two molecules that are important to doing things, the nucleic acid and the protein, 330 00:32:00,000 --> 00:32:05,000 will form first molecules capable of replication. 331 00:32:05,000 --> 00:32:11,000 So, the stepwise process appears to be a beautiful plan 332 00:32:11,000 --> 00:32:17,000 going all the way from the hydrogen atom to the time you get to the intelligent human being. 333 00:32:17,000 --> 00:32:23,000 So, it is a coherent story. It is something that appears to be the most logical. 334 00:32:23,000 --> 00:32:26,000 It is rational. 335 00:32:26,000 --> 00:32:34,000 So, the discovery of life on Mars to people studying the argument of life will be the greatest thing. 336 00:32:34,000 --> 00:32:39,000 As a matter of fact, in my mind, the search for extraterrestrial life is only part of it, 337 00:32:39,000 --> 00:32:44,000 the study of the origin of life. This is the scientifically broader question, 338 00:32:44,000 --> 00:32:51,000 the origin of life in the universe, and bring to Mars the unique opportunity that we have, 339 00:32:51,000 --> 00:32:58,000 perhaps the one only opportunity that we have of showing this great life on Mars, 340 00:32:58,000 --> 00:33:04,000 and especially if we can show that it is origin of different from the origin of life on Earth, 341 00:33:04,000 --> 00:33:12,000 or it is independent, then we will have a very hard thing on the description of uniqueness in life. 342 00:33:12,000 --> 00:33:18,000 New York Times Science Editor, Walter Sullivan, author of the book on which this program is based, 343 00:33:18,000 --> 00:33:24,000 raised this question with Nobel Prize-winning chemist Dr. Harold Urey. 344 00:33:24,000 --> 00:33:28,000 Dr. Urey, a lot of the discussion on the origin of life was down to the question 345 00:33:28,000 --> 00:33:32,000 whether there are other worlds, other solar systems. 346 00:33:32,000 --> 00:33:39,000 You believe there are. It is my belief that if you have conditions such as we have on the Earth, 347 00:33:39,000 --> 00:33:46,000 life will spontaneously appear. I don't know how long it takes, maybe a million years, maybe a billion years, 348 00:33:46,000 --> 00:33:51,000 but sometimes life as we know it will appear. 349 00:33:51,000 --> 00:33:58,000 Every indication is that the properties of the elements and the most distant stars that we look at 350 00:33:58,000 --> 00:34:04,000 are the same as those that we have on Earth. 351 00:34:04,000 --> 00:34:10,000 The physical universe is the same everywhere. That is our conclusion. 352 00:34:10,000 --> 00:34:16,000 The Lord is the same as far as we go, as we understand it. 353 00:34:16,000 --> 00:34:23,000 And this of course means that the chemistry of carbon, nitrogen, oxygen, hydrogen, 354 00:34:23,000 --> 00:34:30,000 the four abundant elements in living things, the chemical properties of these elements 355 00:34:30,000 --> 00:34:35,000 will be the same wherever we are in the universe. 356 00:34:35,000 --> 00:34:45,000 And therefore we expect that they will have the capacity to revolve into what we would call living organisms, 357 00:34:45,000 --> 00:34:50,000 no matter where we go. Now, we don't expect that they will be the same. 358 00:34:50,000 --> 00:34:57,000 Dr. Philip Morrison is Professor of Physics at the Massachusetts Institute of Technology. 359 00:34:57,000 --> 00:35:04,000 The evolution of complex beings, certainly of man and of any other word of the word of the word, 360 00:35:04,000 --> 00:35:08,000 is a very chancey thing. You can show that there were many, many choices. 361 00:35:08,000 --> 00:35:11,000 They had to be made just to choose. This ends on that and that. 362 00:35:11,000 --> 00:35:14,000 And if it hadn't been that way, it wouldn't have been this way. 363 00:35:14,000 --> 00:35:19,000 So for that point of view, you look at the place you've come to, you say, well, it was impossible to get here. 364 00:35:19,000 --> 00:35:24,000 And they say, therefore, it will never happen again in the same way. That's the general view. 365 00:35:24,000 --> 00:35:32,000 I mean, I had to look at the, I guess, right? But if you look at the results, it's quite different. 366 00:35:32,000 --> 00:35:42,000 If I go down the museum across the park here, I can see very beautiful skeletons, impressions, soft-mole impressions, 367 00:35:42,000 --> 00:35:46,000 and even impressions of the fleshy part in the soft stone. 368 00:35:46,000 --> 00:35:49,000 From a beast, I'd forgotten his name. 369 00:35:49,000 --> 00:35:51,000 That's your son. 370 00:35:51,000 --> 00:35:52,000 Yeah. 371 00:35:52,000 --> 00:35:55,000 You're playing that's right. All right. 372 00:35:55,000 --> 00:36:02,000 Who is really reptile and was extinct some hundred and millions of years. 373 00:36:02,000 --> 00:36:05,000 Who swam in the ocean in an apological way as a marine reptile. 374 00:36:05,000 --> 00:36:13,000 And he looks for all the world like a large torpedo-shaped object about eight or ten feet long. 375 00:36:13,000 --> 00:36:21,000 Now then, you look at a tuna, a big tuna. He looks very similar. 376 00:36:21,000 --> 00:36:28,000 Not at all a reptile, but a fish. Quite a difference and really around more primitive objects. 377 00:36:28,000 --> 00:36:37,000 And finally, you may look at a dolphin with a mammal whose ancestors were in land, land, air-breathing, flowers, like ourselves. 378 00:36:37,000 --> 00:36:40,000 They themselves still breathe every two or three minutes comes up. 379 00:36:40,000 --> 00:36:48,000 But all of these beasts were beautifully adapted by flection, by many, many, many generations of careful-fetched, all kinds of genes, 380 00:36:48,000 --> 00:36:55,000 to be able to swim very well, make a living in the scale of eight to ten feet long by catching fat, fishing the sea. 381 00:36:55,000 --> 00:37:01,000 There are many, many paths you get to Central Park, but when you get there, you arrive at the same place. 382 00:37:01,000 --> 00:37:07,000 If you look at any path that you've taken, every turn, every street, you certainly can't predict where I start out exactly how I'll go. 383 00:37:07,000 --> 00:37:09,000 But I'm pretty sure what the end is going to be. 384 00:37:09,000 --> 00:37:12,000 Because that end is not a statuette and I persist when I'm there. 385 00:37:12,000 --> 00:37:16,000 Because there's any chance for a form to evolve on personal fire. 386 00:37:16,000 --> 00:37:19,000 I'm a very complex rich form of life. Let's go back. 387 00:37:19,000 --> 00:37:28,000 Now, if this is true, if it seems reasonable to suppose that there's intelligence on many other planets, what will these photos look like? 388 00:37:28,000 --> 00:37:43,000 I don't know. I think that's more like us than one might believe, but less like us than the common run of what we would regard as human. 389 00:37:43,000 --> 00:37:54,000 In other words, I don't think there'll be 50-foot skeletal figures with long, towering, with long, wirey arms. 390 00:37:54,000 --> 00:37:57,000 I don't think there'll be round spheres of four inches diameter. 391 00:37:57,000 --> 00:38:00,000 That's simply for evolutionary reasons. 392 00:38:00,000 --> 00:38:04,000 Simply for evolutionary reasons. You've got to have a certain size, not too big, not too small. 393 00:38:04,000 --> 00:38:07,000 It's not big enough to have this complicated machinery on it. It can't be too small. 394 00:38:07,000 --> 00:38:12,000 It can't be too big or it's very hard to manage on a planet, but if anything like a chemical composition we're talking about. 395 00:38:13,000 --> 00:38:17,000 But as to inconsequential things, I don't know. 396 00:38:17,000 --> 00:38:22,000 Some people go for it. Some people say, yes, the number of fingers will not be five. 397 00:38:22,000 --> 00:38:29,000 It could be something like fingers. But I would be willing to believe there might be four, there might be eight, there might even be sixteen. 398 00:38:29,000 --> 00:38:33,000 But I don't think there'll be 500. I don't think there'll be one. 399 00:38:33,000 --> 00:38:35,000 We are not alone. 400 00:38:35,000 --> 00:38:41,000 We'll continue with the story of the race for planetary exploration and the UFO controversy. 401 00:38:41,000 --> 00:38:45,000 After this message from the B. F. Goodrich Company. 402 00:38:47,000 --> 00:38:50,000 Meet Jeffrey Masters, your career physicist. 403 00:38:50,000 --> 00:38:54,000 When it comes to splitting atoms, nothing stops Jeffrey. 404 00:38:54,000 --> 00:38:58,000 But when it comes to buying tires, everything does. 405 00:39:02,000 --> 00:39:05,000 Jeffrey is snowed by tire talks. 406 00:39:05,000 --> 00:39:10,000 Cross brace threads, four ply rayon, second line, third line, fourth line. 407 00:39:10,000 --> 00:39:14,000 And faced with tire sizes and tire prices. 408 00:39:14,000 --> 00:39:16,000 He draws a blank. 409 00:39:16,000 --> 00:39:19,000 So Jeffrey has been sold some pretty peculiar tires. 410 00:39:25,000 --> 00:39:30,000 Jeffrey, you know there's got to be an easier way to buy tires. 411 00:39:30,000 --> 00:39:36,000 Come on over to B. F. Goodrich. We've got a brand new way of doing business. We call it straight talk. 412 00:39:37,000 --> 00:39:40,000 We know you don't know a lot of technical tire talk. 413 00:39:40,000 --> 00:39:43,000 But you know a lot about how you drive, right? 414 00:39:43,000 --> 00:39:47,000 Okay, take this. Our B. F. Goodrich tire value calculator. 415 00:39:47,000 --> 00:39:50,000 Come on, work it yourself. Tell us how you draw it. 416 00:39:50,000 --> 00:39:52,000 Now turn it over. 417 00:39:52,000 --> 00:39:56,000 It tells you what kind of B. F. Goodrich tire is best for you. 418 00:39:56,000 --> 00:39:58,000 You don't have to be confused anymore. 419 00:39:58,000 --> 00:40:02,000 You see just what you're getting, just what you're paying for. 420 00:40:02,000 --> 00:40:06,000 Jeffrey, what do you think of B. F. Goodrich's straight talk? 421 00:40:06,000 --> 00:40:09,000 And apparently speaking, I explicitly endorse you. 422 00:40:09,000 --> 00:40:12,000 Yeah, I know it's a lot, Jeff. Tell your friends. 423 00:40:12,000 --> 00:40:18,000 B. F. Goodrich. The straight talk tire people. 424 00:40:20,000 --> 00:40:24,000 Here again, ABC News Correspondent, Edward P. Morgan. 425 00:40:24,000 --> 00:40:30,000 Sometime in 1973, a spacecraft will take off from Earth. 426 00:40:30,000 --> 00:40:33,000 Its name will be Voyager. 427 00:40:44,000 --> 00:40:51,000 The Voyager, a new kind of space vehicle, will begin a trek to the planet Mars. 428 00:40:51,000 --> 00:40:55,000 The first of a series of missions that will eventually carry 429 00:40:55,000 --> 00:41:00,000 sophisticated life detection devices to the Martian surface. 430 00:41:00,000 --> 00:41:05,000 The success of a Voyager mission would be a scientific breakthrough 431 00:41:05,000 --> 00:41:08,000 in our unmanned planetary program. 432 00:41:08,000 --> 00:41:16,000 It will be our first attempt to soft land an instrument package on another planet. 433 00:41:16,000 --> 00:41:24,000 Looking beyond Voyager to 1977, 1979, and the 1980s, 434 00:41:24,000 --> 00:41:30,000 space engineers are already at the hard practical model stage 435 00:41:30,000 --> 00:41:36,000 of designing devices that are still emerging from the minds of scientific dreamers. 436 00:41:36,000 --> 00:41:40,000 One such device designed for a Mars life search 437 00:41:40,000 --> 00:41:46,000 is the automated biological laboratory called an ABL. 438 00:41:46,000 --> 00:41:53,000 One concept of it has been developed by the Aero Neutronic Division of the Philco Corporation. 439 00:41:53,000 --> 00:41:57,000 It would operate remotely and automatically on Mars, 440 00:41:57,000 --> 00:42:02,000 so says space research engineer William Hofstettler. 441 00:42:02,000 --> 00:42:06,000 Basically, there are several processes that can be performed. 442 00:42:06,000 --> 00:42:11,000 First, of course, you have to obtain physical samples of the surface of Mars, 443 00:42:11,000 --> 00:42:17,000 physical samples of the soil, because that's where the organisms will congregate 444 00:42:17,000 --> 00:42:19,000 if there are living organisms. 445 00:42:19,000 --> 00:42:25,000 I might comment, evidently, that we are concerned more with the lower forms of life, 446 00:42:25,000 --> 00:42:32,000 the molecular forms of life, rather than pelopons and horses and so forth. 447 00:42:32,000 --> 00:42:36,000 We are prepared to take pictures of these things if they happen to be there. 448 00:42:36,000 --> 00:42:41,000 The ABL is divided really into three basic integrated subsystems. 449 00:42:41,000 --> 00:42:46,000 One of these is the sampling subsystem that is used to obtain the surface samples 450 00:42:46,000 --> 00:42:49,000 from the soil sample from the surface of Mars. 451 00:42:49,000 --> 00:42:52,000 At the very bottom of the ABL, directly underneath, 452 00:42:52,000 --> 00:42:57,000 there is a system that uses a brush and vacuum system to obtain samples 453 00:42:57,000 --> 00:43:00,000 of the Martian surface directly under the ABL. 454 00:43:00,000 --> 00:43:05,000 Also, there is a core drill system that drills into the surface of our canopy 455 00:43:05,000 --> 00:43:11,000 to obtain subsurface samples, in case the water availability or other conditions 456 00:43:11,000 --> 00:43:17,000 make it more likely as a place for Martian biological life. 457 00:43:17,000 --> 00:43:23,000 A second system picks up samples around the ABL with the samplers you see here, 458 00:43:23,000 --> 00:43:27,000 which is located with our linking to the status of the main body, 459 00:43:27,000 --> 00:43:33,000 and will pick up samples generally around the ABL location. 460 00:43:33,000 --> 00:43:37,000 A third system is used for getting samples from a considerably further distance, 461 00:43:37,000 --> 00:43:43,000 and in particular selected areas that the visual survey system has pointed out 462 00:43:43,000 --> 00:43:48,000 as being particularly desirable because possibly they are warmer than the surrounding spots 463 00:43:48,000 --> 00:43:54,000 or they have a different appearance that might appear to be vegetation or something of that nature. 464 00:43:54,000 --> 00:44:01,000 So, a sampling line is deployed ballisticly, fired out like a small rocket, 465 00:44:01,000 --> 00:44:07,000 carrying this line to some distance up to possibly a thousand feet from the ABL location. 466 00:44:07,000 --> 00:44:12,000 A sampler, then similar to the one that works in the vicinity of the ABL, 467 00:44:12,000 --> 00:44:16,000 is carried up on an elevator latched onto a trolley on this line 468 00:44:16,000 --> 00:44:21,000 and deployed out to the desired spot to obtain the surface sample, 469 00:44:21,000 --> 00:44:26,000 returning and delivering it to the operating parts of the ABL. 470 00:44:26,000 --> 00:44:32,000 These samples are then processed and brought into the interior of the ABL 471 00:44:32,000 --> 00:44:36,000 for chemical processing prior to reading out the experiment. 472 00:44:36,000 --> 00:44:41,000 The chemical processing equipment is located generally in the central area of the ABL 473 00:44:41,000 --> 00:44:47,000 in the form of 13 chemical processes located to come French, we are on the central core. 474 00:44:47,000 --> 00:44:52,000 Certain supplies, water, certain gases are stored in tanks around the center of the ABL. 475 00:44:52,000 --> 00:44:58,000 Other chemical reagents are stored in ampules which hold individual quantities 476 00:44:58,000 --> 00:45:02,000 in this area that surrounds the processors. 477 00:45:02,000 --> 00:45:07,000 These ampules are put into cartridges like this 478 00:45:07,000 --> 00:45:12,000 so that they feed to the outer end and can be picked up by the processing, 479 00:45:12,000 --> 00:45:18,000 by the transport device which internally then moves them to the proper location 480 00:45:18,000 --> 00:45:20,000 to conduct chemical analysis. 481 00:45:20,000 --> 00:45:26,000 After the analysis is completed, the samples are then transferred to the instruments 482 00:45:26,000 --> 00:45:28,000 to read out the experiment results. 483 00:45:28,000 --> 00:45:31,000 The data from these are then processed internally 484 00:45:31,000 --> 00:45:35,000 and transmitted through the high-gain system back to Earth. 485 00:45:35,000 --> 00:45:40,000 If the scientific and engineering problems that must be solved to accomplish this feat 486 00:45:40,000 --> 00:45:46,000 are not overwhelming, the political obstacles may indeed be insurmountable. 487 00:45:46,000 --> 00:45:51,000 Congress will soon have to make the most important decision on space policy 488 00:45:51,000 --> 00:45:57,000 since President Kennedy first won approval to commit us to the Space Age. 489 00:45:57,000 --> 00:46:03,000 The future of planetary exploration will hinge on the outcome of congressional action 490 00:46:03,000 --> 00:46:09,000 that will begin with hearings now set for February 1967. 491 00:46:10,000 --> 00:46:18,000 Because of the need for long lead times, planning policy and funds must be committed now, 492 00:46:18,000 --> 00:46:22,000 not only for the Voyager program in 1973, 493 00:46:22,000 --> 00:46:29,000 but for the life detection missions to Mars and Venus to come in the next decade or two. 494 00:46:29,000 --> 00:46:35,000 Whether the Soviet Union has its equivalent of our Voyager ready to shoot for Mars or Venus 495 00:46:35,000 --> 00:46:37,000 is no longer in question. 496 00:46:37,000 --> 00:46:44,000 In Russia, cosmic expositions and public displays of space vehicles are commonplace. 497 00:46:44,000 --> 00:46:49,000 Interest in planetary exploration and the search for extraterrestrial life 498 00:46:49,000 --> 00:46:53,000 is at a high pitch among scientists and the public alike. 499 00:46:53,000 --> 00:47:00,000 If our race for space with the Soviet Union were to be judged by who will first land a man on the moon, 500 00:47:00,000 --> 00:47:05,000 the contest at this stage might be considered a dead heat. 501 00:47:05,000 --> 00:47:09,000 But if the second lap of this race is one of planetary discovery 502 00:47:09,000 --> 00:47:15,000 on which depends the exciting scientific trophies of the foreseeable future, 503 00:47:15,000 --> 00:47:19,000 then the United States is estimated far behind. 504 00:47:19,000 --> 00:47:27,000 Soviet cosmonauts, male and female, become the honored protégés of the state, 505 00:47:27,000 --> 00:47:31,000 symbols of Soviet communist achievement. 506 00:47:32,000 --> 00:47:38,000 Not so burdened by war costs, the Soviet budget, according to a recent analysis, 507 00:47:38,000 --> 00:47:45,000 has allocated to planetary exploration from five to ten times as much as the United States, 508 00:47:45,000 --> 00:47:51,000 and as a result, the great discoveries concerning our neighboring planets, Mars and Venus, 509 00:47:51,000 --> 00:47:57,000 will be made by the Russians unless early steps are taken to escalate the American effort. 510 00:47:58,000 --> 00:48:03,000 In the field of radio astronomy too, the Soviets have been more consistently searching 511 00:48:03,000 --> 00:48:11,000 for extraterrestrial signals and recently reported having observed beacons of an interstellar civilization. 512 00:48:11,000 --> 00:48:16,000 Although later observations by American scientists negated their claims, 513 00:48:16,000 --> 00:48:21,000 the Russians never completely revised their earlier contention. 514 00:48:21,000 --> 00:48:26,000 However, in the area of the extraterrestrial life search, 515 00:48:26,000 --> 00:48:32,000 they have held the door open to international cooperation, says astronomer Carl Sagan. 516 00:48:32,000 --> 00:48:40,000 They have made a recommendation that a worldwide international cooperation be established 517 00:48:40,000 --> 00:48:46,000 for a further growing search of large numbers of stars and galaxies 518 00:48:46,000 --> 00:48:51,000 to see if there is any intelligible radio communication being sent. 519 00:48:51,000 --> 00:48:59,000 And who knows if possible, if there is a collaborative effort like the established previous collaborative efforts, 520 00:48:59,000 --> 00:49:04,000 for example the I.G.Y. between the United States, Soviet Union and other countries, 521 00:49:04,000 --> 00:49:09,000 have been enormously productive scientifically and in fact in other ways. 522 00:49:09,000 --> 00:49:15,000 A persistent furor in the past few years is the one over the alleged sightings 523 00:49:15,000 --> 00:49:22,000 of flying saucers. The number of officially reported sightings of UFOs, 524 00:49:22,000 --> 00:49:30,000 unidentified flying objects, has risen from 399 in 1963 to more than 1500 525 00:49:30,000 --> 00:49:35,000 in the last 18 months according to U.S. Air Force figures. 526 00:49:35,000 --> 00:49:40,000 A cult of enthusiasts has developed, promoting the theory that these phenomena 527 00:49:40,000 --> 00:49:44,000 are visitations from intelligent beings in outer space. 528 00:49:44,000 --> 00:49:52,000 And according to a recent Gallup poll, about 5 million people have reported seeing UFOs over the years. 529 00:49:52,000 --> 00:49:58,000 Organizations with names like Flying Saucer News Club of America 530 00:49:58,000 --> 00:50:04,000 and National Investigations Committee on Aerial Phenomena, which has doubled its membership 531 00:50:04,000 --> 00:50:11,000 of 5,000 in the last year and a half, have sprung up complete with annual conventions, 532 00:50:11,000 --> 00:50:17,000 recruiting drives and publicity bulletins arguing for acceptance of the idea 533 00:50:17,000 --> 00:50:24,000 that flying saucers must be dealt with as emissaries far out-diplomats from space. 534 00:50:24,000 --> 00:50:29,000 The scientific community, even though scientists committed to the belief 535 00:50:29,000 --> 00:50:34,000 that other intelligent life does exist somewhere in the cosmos, 536 00:50:34,000 --> 00:50:39,000 has greeted the flying saucer theory in the main with open skepticism. 537 00:50:39,000 --> 00:50:45,000 Physicist Dr. Philip Morrison of Massachusetts Institute of Technology. 538 00:50:45,000 --> 00:50:49,000 The social phenomena, the phenomena of journalism and television. 539 00:50:49,000 --> 00:50:53,000 If you look in the record newspapers, 100 to 120 years ago, 540 00:50:53,000 --> 00:50:57,000 exactly the same things were seen, exactly the same stories were given. 541 00:50:57,000 --> 00:51:02,000 They're much more frequent now. And what has happened is a infernal invention of the phrase, 542 00:51:02,000 --> 00:51:08,000 the flying saucer. However, most of the things they see are, as we all well know, 543 00:51:08,000 --> 00:51:12,000 planets and lights in the sky and aircraft and so on. 544 00:51:12,000 --> 00:51:17,000 And I think one of the most striking evidences, if I may exploit the subterraneanity, 545 00:51:17,000 --> 00:51:22,000 that we don't really have a deep spread of understanding and education in science 546 00:51:22,000 --> 00:51:26,000 is the fact that people are not able to cope with the phenomena they see 547 00:51:26,000 --> 00:51:29,000 in any other way than inventing what I agree is a possible theory, 548 00:51:29,000 --> 00:51:33,000 but a very much more improbable theory than most of the things it describes in fact. 549 00:51:33,000 --> 00:51:38,000 And I think there's a sneaking suspicion, also in the literature of the flying saucer, 550 00:51:38,000 --> 00:51:42,000 that this is just some terrestrial object of secret kind, 551 00:51:42,000 --> 00:51:46,000 which is surely another social phenomenon in response to the enormous importance 552 00:51:46,000 --> 00:51:49,000 given to secrecy and military preparations in secret, 553 00:51:49,000 --> 00:51:52,000 which is the characteristic feature of the last 20 or 30 years. 554 00:51:52,000 --> 00:51:55,000 And if you take these two things out of it, then you don't have a great deal left, 555 00:51:55,000 --> 00:52:00,000 except a lot of interesting phenomena seen by people, some of which are new and quite unexplained 556 00:52:00,000 --> 00:52:04,000 and would be nice to find out more about, but a great many of which are rather familiar things, 557 00:52:04,000 --> 00:52:06,000 the under-unfamiliarity. 558 00:52:06,000 --> 00:52:11,000 We are not alone. We'll continue with the religious and philosophical implications 559 00:52:11,000 --> 00:52:15,000 that would result from the discovery of life on other worlds 560 00:52:15,000 --> 00:52:18,000 after this message from the B.F. Goodrich Company. 561 00:52:18,000 --> 00:52:24,000 Music 562 00:52:24,000 --> 00:52:29,000 How come the typical American motorist puts off flying tires 563 00:52:29,000 --> 00:52:32,000 until they can't put it off any longer? 564 00:52:32,000 --> 00:52:34,000 Shhhhhh! 565 00:52:34,000 --> 00:52:39,000 Music 566 00:52:39,000 --> 00:52:44,000 Maybe it's because the typical American tire store is like a foreign country. 567 00:52:45,000 --> 00:52:49,000 Alone you were over the range of different languages. 568 00:52:49,000 --> 00:52:53,000 When you asked for help, you needed an interpreter to help you with the answers. 569 00:52:53,000 --> 00:52:56,000 And when you finally get the bill. 570 00:52:56,000 --> 00:52:59,000 Music 571 00:52:59,000 --> 00:53:02,000 Now you don't have to let tire buying get you down. 572 00:53:02,000 --> 00:53:04,000 Go see B.F.

593 00:54:01,000 --> 00:54:03,000 The possibility cannot be dismissed. 594 00:54:03,000 --> 00:54:07,000 The prospect has captured the imaginations and stirred the emotions 595 00:54:07,000 --> 00:54:10,000 of scientists and laymen alike. 596 00:54:10,000 --> 00:54:16,000 One of the stunning questions raised by the possibility of life on other planets 597 00:54:16,000 --> 00:54:19,000 in other solar systems is this. 598 00:54:19,000 --> 00:54:23,000 If proved, what will it do to theology? 599 00:54:23,000 --> 00:54:27,000 Man has been inclined to conceive of himself as cast in an earthly 600 00:54:27,000 --> 00:54:31,000 but divine image of God or gods. 601 00:54:31,000 --> 00:54:36,000 What if God supervised the beginnings of other civilizations 602 00:54:36,000 --> 00:54:38,000 on other planets first? 603 00:54:38,000 --> 00:54:44,000 Do the Martians, if any, have their equivalent of Adam and Eve? 604 00:54:44,000 --> 00:54:48,000 Did somebody else out there discover long before Darwin 605 00:54:48,000 --> 00:54:51,000 the Darwinian theory of evolution? 606 00:54:51,000 --> 00:54:56,000 These and countless other related religious questions, of course, 607 00:54:56,000 --> 00:55:01,000 must await the results of these new Christopher Columbus voyages 608 00:55:01,000 --> 00:55:05,000 of science through the solar system. 609 00:55:05,000 --> 00:55:10,000 Dr. Martin, for centuries, and really ever since man evolved on this planet, 610 00:55:10,000 --> 00:55:14,000 he thought of himself as being central, as being unique, 611 00:55:14,000 --> 00:55:19,000 as being the supreme representation of life. 612 00:55:19,000 --> 00:55:22,000 Supposing we discover that this is not the case, 613 00:55:22,000 --> 00:55:24,000 we know we're not central, 614 00:55:24,000 --> 00:55:29,000 suppose we discover we're also not really as superior as other beings elsewhere. 615 00:55:29,000 --> 00:55:33,000 When is going to be the effect of this on our concept of our place in the universe 616 00:55:33,000 --> 00:55:37,000 and of ourselves and the everyone who tries to think of himself 617 00:55:37,000 --> 00:55:43,000 as having a view of the world and seeing his place in whatever his attitudes 618 00:55:43,000 --> 00:55:47,000 will agree, I think, that above all, you have to be true. 619 00:55:47,000 --> 00:55:48,000 What's right now? 620 00:55:48,000 --> 00:55:51,000 If it turns out we have to adjust to this, certainly we can do so. 621 00:55:51,000 --> 00:55:56,000 I think in some ways we move what must be an essential loneliness of this tradition, 622 00:55:56,000 --> 00:56:00,000 of the Arabian sense of responsibility, one of the structures, not all ours. 623 00:56:00,000 --> 00:56:05,000 Is it not true that, at least in the western world, 624 00:56:05,000 --> 00:56:11,000 in the galactic community, as far as the Yoram Mountains, 625 00:56:11,000 --> 00:56:13,000 the Europe of the North America, 626 00:56:13,000 --> 00:56:20,000 there's been a lengthy tradition of saying that all that is most valuable 627 00:56:20,000 --> 00:56:25,000 and the view of life, the view of the state, the view of the individual, the view of morality, 628 00:56:25,000 --> 00:56:29,000 a great deal of that comes, of course, from our religious development. 629 00:56:29,000 --> 00:56:36,000 But an equally large, or almost equally large, contribution comes from the study of societies 630 00:56:36,000 --> 00:56:39,000 which are absolutely gone, which only never again communicate, 631 00:56:39,000 --> 00:56:42,000 the most important being the world of Greece. 632 00:56:42,000 --> 00:56:48,000 The Greek playwright, the Greek philosophers, the Greek historians and statesmen are, 633 00:56:48,000 --> 00:56:53,000 their thought and what they did is on the lips and on the pens 634 00:56:53,000 --> 00:56:55,000 of most of the most learned people in the world. 635 00:56:55,000 --> 00:56:59,000 All we have is containing about 10 or 15,000 books, 636 00:56:59,000 --> 00:57:04,000 which are a small library easily held in a good size office. 637 00:57:04,000 --> 00:57:08,000 Those are all the Greek texts about everything that we will ever have, 638 00:57:08,000 --> 00:57:12,000 and yet scholars and students have gone over and over and over those, and they're terribly valuable. 639 00:57:12,000 --> 00:57:16,000 Now we've extended that in our time because most of us are by studying other cultures 640 00:57:16,000 --> 00:57:19,000 with their rich traditions, the culture of the Orient, the culture of the Orient, 641 00:57:19,000 --> 00:57:25,000 the cultures of America, old America, the cultures of West Africa and so on, 642 00:57:25,000 --> 00:57:29,000 each of which have been contributions and give us a lot of understanding, a lot of insight. 643 00:57:29,000 --> 00:57:34,000 And I don't even make a real human culture until we have all of this said in. 644 00:57:34,000 --> 00:57:39,000 And I think on top of that, enriching it by having the story equally complex and much longer, 645 00:57:39,000 --> 00:57:44,000 but in less detail, which was the kind of thing we'd have to have from some remote society, 646 00:57:44,000 --> 00:57:51,000 could do anything but add a tremendous challenge and enrichment and satisfaction to those people. 647 00:57:51,000 --> 00:57:55,000 Indeed, I think if I put this over their place, that's the reason they would do it. 648 00:57:55,000 --> 00:57:59,000 Because then, the added to their libraries too, what our history has been, 649 00:57:59,000 --> 00:58:02,000 and that must be the only thing they can guess from science, 650 00:58:02,000 --> 00:58:07,000 the complexity of playwriting or the histories of kings or folk lore, 651 00:58:07,000 --> 00:58:10,000 you can get their general part, but the detail is too rich. 652 00:58:10,000 --> 00:58:13,000 You can easily show it mathematically. There's just too many possibilities. 653 00:58:13,000 --> 00:58:19,000 But they will also be happy to have one more library coming into their signals, and that's what I'd like to put. 654 00:58:19,000 --> 00:58:21,000 Mr. Walter Sullivan. 655 00:58:21,000 --> 00:58:28,000 What a wonderful planet is our world and how far it may be to anything else like it. 656 00:58:28,000 --> 00:58:33,000 We are reasonably believe there are other planets, less to our advantages, 657 00:58:33,000 --> 00:58:39,000 a kindly, stable, parent star, a well-placed orbit, a suitable atmosphere, 658 00:58:39,000 --> 00:58:47,000 dry continents for advanced life forms, great seas within which their primitive ancestors evolved. 659 00:58:47,000 --> 00:58:55,000 But the fragile green hue of life appears only here and there on our planet as things in space. 660 00:58:55,000 --> 00:59:05,000 Its hold is tenuous. If any great passion overcome reason, we can now render the planet uninhabitable. 661 00:59:05,000 --> 00:59:10,000 Is that the face of all technological societies? 662 00:59:10,000 --> 00:59:18,000 It is up to us on this wonderful world of ours to prove that it is not so. 663 00:59:18,000 --> 00:59:33,000 We are not alone. 664 00:59:33,000 --> 00:59:59,000 This has been a presentation of ABC News.
