...first photographs, none of the Viking scientists seemed particularly disappointed that the pictures showed no obvious signs of life-no lichen, bushes or trees, nothing even remotely resembling an animal or the monsters or little green men beloved by generations of science-fiction writers. Said Exobiologist Carl Sagan: "The pictures do not suggest that the planet is filled, pole to pole, with living things." But, noted Sagan, nothing in the pictures ruled out the existence of life on the planet either. Soffen added that the lander's immediate vicinity held half a dozen niches in which conventional biology, including...
...should have been the greatest letdown for the true believers. In 1965 Mariner 4 passed within 6,118 miles of the Martian surface and returned pictures showing what seemed to be a lifeless, cratered, moonlike planet. But even those desolate scenes failed to dissuade the diehards. In 1965 Carl Sagan-then a relatively unknown Harvard astronomer, now the best-known proponent of Martian life and a member of the Viking-lander photoanalysis team-suggested that had a Martian version of Mariner 4 passed within 6,000 miles of earth and taken 22 comparable photographs, it would have uncovered no sign...
...could dramatically show that there indeed is or was life on Mars. Shots of Fletcher's "eye"- or a scraggly plant or an obvious fossil- would provide instant and sensational evidence that might forever change man's view of himself, his world and the universe. In fact, Sagan and Stanford University Geneticist Joshua Lederberg have suggested that large organisms could have evolved in the cold and arid environment of Mars. Because a big animal has less surface area in relation to its volume than a smaller one, and because it is from an animal's surface that...
...with space colonies. It runs 48 pages, featuring 76 famous people or friends of Stewart Brand (guiding light of The Catalog and editor of The Quarterly) writing on what they think about the possibilities of building cities in space. The article includes not only such popular scientists as Carl Sagan, Lewis Mumford, and Buckminister Fuller, but also Richard Brautigan and poet Gary Snyder...
Because LAGEOS is expected to remain in orbit for so long, NASA has placed aboard it two stainless-steel sheets, each etched with a message conceived by Astrophysicist Carl Sagan of Cornell University. Designed to inform extraterrestrial visitors or future inhabitants of the earth about the LAGEOS mission, the message shows three maps of the earth, depicting the continental drift that the satellite will help observe. The uppermost of the maps shows the continents as they are thought to have existed 225 million years ago, when Africa and South America were joined. The middle map is a picture...
