Carl Edward Sagan was an American astronomer, planetary scientist, cosmologist, astrophysicist, astrobiologist, author, and science communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space, the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them. Sagan argued the hypothesis, accepted since, that the high surface temperatures of Venus can be attributed to, and calculated using, the greenhouse effect. He testified to the US Congress in 1985 that the greenhouse effect will change the earth's climate system.
Mariner 4 was the fourth in a series of spacecraft intended for planetary exploration in a flyby mode. It was designed to conduct closeup scientific observations of Mars and to transmit these observations to Earth. Launched on November 28, 1964, Mariner 4 performed the first successful flyby of the planet Mars, returning the first close-up pictures of the Martian surface. It captured the first images of another planet ever returned from deep space; their depiction of a cratered, dead planet largely changed the scientific community's view of life on Mars. Other mission objectives were to perform field and particle measurements in interplanetary space in the vicinity of Mars and to provide experience in and knowledge of the engineering capabilities for interplanetary flights of long duration. On December 21, 1967, communications with Mariner 4 were terminated.
Fictional representations of Mars have been popular for over a century. Interest in Mars has been stimulated by the planet's dramatic red color, by early scientific speculations that its surface conditions might be capable of supporting life, and by the possibility that Mars could be colonized by humans in the future. Almost as popular as stories about Mars are stories about Martians engaging in activity away from their home planet. The ideas of Mars would grow and change with new scientific discoveries changing the way Mars would be seen in the science fiction world.
Ray Douglas Bradbury was an American author and screenwriter. One of the most celebrated 20th-century American writers, he worked in a variety of modes, including fantasy, science fiction, horror, mystery, and realistic fiction.
The Martian Chronicles is a science fiction fix-up novel, published in 1950, by American writer Ray Bradbury that chronicles the exploration and settlement of Mars, the home of indigenous Martians, by Americans leaving a troubled Earth that is eventually devastated by nuclear war.
The Planetary Society is an American internationally-active non-governmental nonprofit organization. It is involved in research, public outreach, and political space advocacy for engineering projects related to astronomy, planetary science, and space exploration. It was founded in 1980 by Carl Sagan, Bruce Murray, and Louis Friedman, and has about 60,000 members from more than 100 countries around the world.
Richard Charles Hoagland, is an American author and a proponent of various conspiracy theories about NASA, lost alien civilizations on the Moon and on Mars and other related topics. Hoagland has been documented to misappropriate others' professional achievements and is widely described as a conspiracy theorist and fringe pseudoscientist.
James Barney Pollack was an American astrophysicist who worked for NASA's Ames Research Center.
Eric Burgess was an English freelance consultant, lecturer and journalist, who wrote about the Pioneer program of space missions since the first tests in 1957. He was the science correspondent of the Christian Science Monitor in the period of many of the planetary probe launches, and was often the senior science reporter present at many of those events.
First contact is a common science fiction theme about the first meeting between humans and extraterrestrial life, or of any sentient species' first encounter with another one, given they are from different planets or natural satellites. The theme allows writers to explore such topics such as xenophobia, transcendentalism, and basic linguistics by adapting the anthropological topic of first contact to extraterrestrial cultures.
The first Golden Age of Science Fiction, often recognized in the United States as the period from 1938 to 1946, was an era during which the science fiction genre gained wide public attention and many classic science fiction stories were published. In the history of science fiction, the Golden Age follows the "pulp era" of the 1920s and 1930s, and precedes New Wave science fiction of the 1960s and 1970s. The 1950s are a transitional period in this scheme; however, Robert Silverberg, who came of age in the 1950s, saw that decade as the true Golden Age.
Cosmos is a 1980 popular science book by astronomer and Pulitzer Prize-winning author Carl Sagan. Its 13 illustrated chapters, corresponding to the 13 episodes of the Cosmos TV series, which the book was co-developed with and intended to complement, explore the mutual development of science and civilization. One of Sagan's main purposes for the book and television series was to explain complex scientific ideas to anyone interested in learning. Sagan also believed the television was one of the greatest teaching tools ever invented, so he wished to capitalize on his chance to educate the world. Spurred in part by the popularity of the TV series, Cosmos spent 50 weeks on the Publishers Weekly best-sellers list and 70 weeks on the New York Times Best Seller list to become the best-selling science book ever published at the time. In 1981, it received the Hugo Award for Best Non-Fiction Book. The book's unprecedented success ushered in a dramatic increase in visibility for science-themed literature. The success of the book also jumpstarted Sagan's literary career. The sequel to Cosmos is Pale Blue Dot: A Vision of the Human Future in Space (1994).
Bruce Churchill Murray was an American planetary scientist. He was a director of the Jet Propulsion Laboratory (JPL) and co-founder of The Planetary Society.
Diane Ackerman is an American poet, essayist, and naturalist known for her wide-ranging curiosity and poetic explorations of the natural world.
"There Will Come Soft Rains" is a science fiction short story by author Ray Bradbury written as a chronicle about a lone house that stands intact in a California city that has otherwise been obliterated by a nuclear bomb, and then is destroyed in a fire caused by a windstorm. First published in 1950 about future catastrophes in two different versions in two separate publications, a one-page short story in Collier's magazine and a chapter of the fix-up novel The Martian Chronicles, the author regarded it as "the one story that represents the essence of Ray Bradbury." Bradbury's foresight in recognizing the potential for the complete self-destruction of humans by nuclear war in the work was recognized by the Pulitzer Prize Board in conjunction with awarding a Special Citation in 2007 that noted, "While time has (mostly) quelled the likelihood of total annihilation, Bradbury was a lone voice among his contemporaries in contemplating the potentialities of such horrors." The author considered the short story as the only one in The Martian Chronicles to be a work of science fiction.
The following is a list of works by Arthur C. Clarke.
Bradbury Landing is the 6 August 2012, landing site within Gale crater on planet Mars of the Mars Science Laboratory (MSL) Curiosity rover. On 22 August 2012 on what would have been his 92nd birthday, NASA named the site for author Ray Bradbury, who had died on 5 June 2012. The coordinates of the landing site on Mars are: 4.5895°S 137.4417°E.
