Janusz Andrzej Zajdel was a Polish science fiction author, second in popularity in Poland to Stanisław Lem. His major genres were social science fiction and dystopia. His main recurring theme involved the gloomy prospects for a space environment into which mankind carried totalitarian ideas and habits: Red Space Republics, or Space Labor Camps, or both. His heroes desperately try to find meaning in the world around them.
Known Space is the fictional setting of about a dozen science fiction novels and several collections of short stories by American writer Larry Niven. It has also become a shared universe in the spin-off Man-Kzin Wars anthologies. The Internet Speculative Fiction Database (ISFDB) catalogs all works set in the fictional universe that includes Known Space under the series name Tales of Known Space, which was the title of a 1975 collection of Niven's short stories. The first-published work in the series, which was Niven's first published piece, was "The Coldest Place", in the December 1964 issue of If magazine, edited by Frederik Pohl. This was the first-published work in the 1975 collection.
Ringworld is a 1970 science fiction novel by Larry Niven, set in his Known Space universe and considered a classic of science fiction literature. Ringworld tells the story of Louis Wu and his companions on a mission to the Ringworld, a rotating wheel artificial world, an alien construct in space 186 million miles in diameter. Niven later added three sequel novels and then cowrote, with Edward M. Lerner, four prequels and a final sequel; the five latter novels constitute the Fleet of Worlds series. All the novels in the Ringworld series tie into numerous other books set in Known Space. Ringworld won the Nebula Award in 1970, as well as both the Hugo Award and Locus Award in 1971.
Space exploration is the use of astronomy and space technology to explore outer space. While the exploration of space is currently carried out mainly by astronomers with telescopes, its physical exploration is conducted both by uncrewed robotic space probes and human spaceflight. Space exploration, like its classical form astronomy, is one of the main sources for space science.
The Fountains of Paradise is a 1979 science fiction novel by British writer Arthur C. Clarke. Set in the 22nd century, it describes the construction of a space elevator. This "orbital tower" is a giant structure rising from the ground and linking with a satellite in geostationary orbit at the height of approximately 36,000 kilometers. Such a structure would be used to raise payloads to orbit without the expense of using rockets. The novel won both the Hugo and Nebula Awards for Best Novel.
Between Planets is a juvenile science fiction novel by American writer Robert A. Heinlein, originally serialized in Blue Book magazine in 1951 as "Planets in Combat". It was published in hardcover that year by Scribner's as part of the Heinlein juveniles.
An orrery is a mechanical model of the Solar System that illustrates or predicts the relative positions and motions of the planets and moons, usually according to the heliocentric model. It may also represent the relative sizes of these bodies; however, since accurate scaling is often not practical due to the actual large ratio differences, a subdued approximation may be used instead. Though the Greeks had working planetaria, the first orrery that was a planetarium of the modern era was produced in 1713, and one was presented to Charles Boyle, 4th Earl of Orrery – hence the name. They are typically driven by a clockwork mechanism with a globe representing the Sun at the centre, and with a planet at the end of each of the arms.
A megastructure is a very large artificial object, although the limits of precisely how large vary considerably. Some apply the term to any especially large or tall building. Some sources define a megastructure as an enormous self-supporting artificial construct. The products of megascale engineering or astroengineering are megastructures. The lower bound of megastructural engineering might be considered any structure that has any single dimension 1 megameter (1000 km) in length.
The Sands of Mars is a science fiction novel by English writer Arthur C. Clarke. While he was already popular as a short story writer and as a magazine contributor, The Sands of Mars was also a prelude to Clarke's becoming one of the world's foremost writers of science fiction novels. The story was published in 1951, before humans had achieved space flight. It is set principally on the planet Mars, which has been settled by humans and is used essentially as a research establishment. The story setting is that Mars has been surveyed but not fully explored on the ground. The Sands of Mars was Clarke's first published novel.
An orbital ring is a concept of an artificial ring placed around a body and set rotating at such a rate that the apparent centrifugal force is large enough to counteract the force of gravity. For the Earth, the required speed is on the order of 10 km/sec, compared to a typical low Earth orbit velocity of 8 km/sec. The structure is intended to be used as a space station or as a planetary vehicle for very high-speed transportation or space launch.
In both science fiction and utopia/dystopian fiction, authors have made frequent use of the age-old idea of a global state and, accordingly, of world government.
A World Out of Time is a science fiction novel by Larry Niven and published in 1976. It is set outside the Known Space universe of many of Niven's stories, but is otherwise fairly representative of his 1970s hard science fiction novels. The main part of the novel was originally serialized in Galaxy magazine as "Children of the State"; another part was originally published as the short story "Rammer". A World Out of Time placed fifth in the annual Locus Poll in 1977.
The Hour of the Bull is a social science fiction novel written by Soviet author and paleontologist Ivan Yefremov in 1968. Six months after its publication in book form in 1970 Soviet authorities attempted to remove it from libraries and bookshops after realizing that it contained a sharp criticism of the current state of affairs in the USSR disguised as a critique of "Capitalism" and Chinese-style communism of that time. It was published again in the 1980s "perestrojka" and thereafter.
This is a list of occurrences of space elevators in fiction. Some depictions were made before the space elevator concept became fully established.
The Alliance–Union universe is a fictional universe created by American writer C. J. Cherryh. It is the setting for a future history series extending from the 21st century into the far future.
The fictional portrayal of the Solar System has often included planets, moons, and other celestial objects which do not actually exist in reality. Some of these objects were, at one time, seriously considered as hypothetical planets which were either thought to have been observed, or were hypothesized to be orbiting the Sun in order to explain certain celestial phenomena. Often such objects continued to be used in literature long after the hypotheses upon which they were based had been abandoned.
The planetary systems of stars other than the Sun and the Solar System are a staple element in many works of the science fiction genre.
Between the Strokes of Night (1985) is a science fiction novel by English-American writer Charles Sheffield. It first appeared in the March to June 1985 issues of Analog Science Fiction/Science Fact before being published by Baen Books in July 1985. The story is divided into two vastly separated periods: the near future of 2010, and the far future of 29,000 AD. Owing to the unique technological mechanisms of the novel, the same cast of characters appears in both parts, though it is not a time travel story.
A rotating wheel space station, also known as a von Braun wheel, is a concept for a hypothetical wheel-shaped space station. Originally proposed by Konstantin Tsiolkovsky in 1903, the idea was expanded by Herman Potočnik in 1929.
