This was followed by five launches of boilerplate CSMs (designated AS-101 through AS-105 ) into orbit in 1964 and 1965. The last three of these further supported the Apollo program by also carrying Pegasus satellites, which verified the safety of the translunar environment by measuring
7770-640: The first true science fiction novel . Jules Verne and H.G. Wells are pivotal figures in the genre's development. In the 20th century, expanded with the introduction of space operas , dystopian literature, pulp magazines , and the Golden Age of Science Fiction . Science fiction has been called the "literature of ideas ", and continues to evolve, incorporating diverse voices and themes, influencing not just literature but film, TV, and culture at large. Besides providing entertainment it can also criticize present-day society and explore alternatives, and inspiration
7881-445: The frequency and severity of micrometeorite impacts. In September 1962, NASA planned to launch four crewed CSM flights on the Saturn I from late 1965 through 1966, concurrent with Project Gemini. The 22,500-pound (10,200 kg) payload capacity would have severely limited the systems which could be included, so the decision was made in October 1963 to use the uprated Saturn IB for all crewed Earth orbital flights. The Saturn IB
7992-480: The genre, it describes the history of humanity from the present onwards across two billion years. In 1937, John W. Campbell became editor of Astounding Science Fiction , an event that is sometimes considered the beginning of the Golden Age of Science Fiction , which was characterized by stories celebrating scientific achievement and progress . The "Golden Age" is often said to have ended in 1946, but sometimes
8103-498: The heavy lift-class Saturn launch vehicles , which would be required for Apollo. It became clear that managing the Apollo program would exceed the capabilities of Robert R. Gilruth 's Space Task Group , which had been directing the nation's crewed space program from NASA's Langley Research Center . So Gilruth was given authority to grow his organization into a new NASA center, the Manned Spacecraft Center (MSC). A site
8214-472: The implications of the Internet and the expanding information universe, questions about biotechnology , nanotechnology , and post-scarcity societies . Recent trends and subgenres include steampunk , biopunk , and mundane science fiction . The first, or at least one of the first, recorded science fiction film is 1902's A Trip to the Moon , directed by French filmmaker Georges Méliès . It
8325-485: The important weight reductions that were offered by the LOR approach. Throughout 1960 and 1961, Houbolt campaigned for the recognition of LOR as a viable and practical option. Bypassing the NASA hierarchy, he sent a series of memos and reports on the issue to Associate Administrator Robert Seamans; while acknowledging that he spoke "somewhat as a voice in the wilderness", Houbolt pleaded that LOR should not be discounted in studies of
8436-492: The initial design should be continued as Block I which would be used for early testing, while Block II, the actual lunar spacecraft, would incorporate the docking equipment and take advantage of the lessons learned in Block I development. The Apollo Lunar Module (LM) was designed to descend from lunar orbit to land two astronauts on the Moon and take them back to orbit to rendezvous with the command module. Not designed to fly through
8547-405: The interface between technology and society, and climate fiction , addressing environmental issues. Precedents for science fiction are argued to exist as far back as antiquity, but the modern genre primarily arose in the 19th and early 20th centuries when popular writers began looking to technological progress and speculation. Mary Shelley 's Frankenstein , written in 1818, is often credited as
8658-527: The intersection of other more concrete subgenres. Damon Knight summed up the difficulty, saying "Science fiction is what we point to when we say it." Forrest J Ackerman has been credited with first using the term "sci-fi" (analogous to the then-trendy " hi-fi ") in about 1954. The first known use in print was a description of Donovan's Brain by movie critic Jesse Zunser in January 1954. As science fiction entered popular culture , writers and fans active in
8769-415: The late 1940s and the 1950s are included. In 1942, Isaac Asimov started his Foundation series , which chronicles the rise and fall of galactic empires and introduced psychohistory . The series was later awarded a one-time Hugo Award for "Best All-Time Series". Theodore Sturgeon 's More Than Human (1953) explored possible future human evolution . In 1957, Andromeda: A Space-Age Tale by
8880-450: The long-range exploration of space; and none will be so difficult or expensive to accomplish. At the time of Kennedy's proposal, only one American had flown in space—less than a month earlier—and NASA had not yet sent an astronaut into orbit. Even some NASA employees doubted whether Kennedy's ambitious goal could be met. By 1963, Kennedy even came close to agreeing to a joint US-USSR Moon mission, to eliminate duplication of effort. With
8991-510: The lunar flights. On the extended lunar missions, an orbital scientific instrument package was carried. The service module was discarded just before reentry. The module was 24.6 feet (7.5 m) long and 12.83 feet (3.91 m) in diameter. The initial lunar flight version weighed approximately 51,300 pounds (23,300 kg) fully fueled, while a later version designed to carry a lunar orbit scientific instrument package weighed just over 54,000 pounds (24,000 kg). North American Aviation won
9102-472: The novellas included in the first novel, Dragonflight , made McCaffrey the first woman to win a Hugo or Nebula Award . In 1968, Philip K. Dick 's Do Androids Dream of Electric Sheep? was published. It is the literary source of the Blade Runner movie franchise . In 1969, The Left Hand of Darkness by Ursula K. Le Guin was set on a planet in which the inhabitants have no fixed gender . It
9213-553: The performance of a soft landing system compared to expendable vehicles , all other things being equal. The main benefit of the technology is seen in the potential for substantial reductions in space flight costs as a result of being able to reuse rockets after successful VTVL landings. Vertical landing of spaceships was the predominant mode of rocket landing envisioned in the pre- spaceflight era. Many science fiction authors as well as depictions in popular culture showed rockets landing vertically, typically resting after landing on
9324-603: The play RUR , written by the Czech playwright Karel Čapek , broadcast live from the BBC's Alexandra Palace studios on 11 February 1938. The first popular science fiction program on American television was the children's adventure serial Captain Video and His Video Rangers , which ran from June 1949 to April 1955. The Twilight Zone (the original series), produced and narrated by Rod Serling , who also wrote or co-wrote most of
9435-478: The press, during a presentation by von Braun. Webb jumped in and defended von Braun, until Kennedy ended the squabble by stating that the matter was "still subject to final review". Webb held firm and issued a request for proposal to candidate Lunar Excursion Module (LEM) contractors. Wiesner finally relented, unwilling to settle the dispute once and for all in Kennedy's office, because of the President's involvement with
9546-540: The project was overseen by Thomas J. Kelly . Before the Apollo program began, Wernher von Braun and his team of rocket engineers had started work on plans for very large launch vehicles, the Saturn series , and the even larger Nova series. In the midst of these plans, von Braun was transferred from the Army to NASA and was made Director of the Marshall Space Flight Center. The initial direct ascent plan to send
9657-519: The question. Seamans's establishment of an ad hoc committee headed by his special technical assistant Nicholas E. Golovin in July 1961, to recommend a launch vehicle to be used in the Apollo program, represented a turning point in NASA's mission mode decision. This committee recognized that the chosen mode was an important part of the launch vehicle choice, and recommended in favor of a hybrid EOR-LOR mode. Its consideration of LOR—as well as Houbolt's ceaseless work—played an important role in publicizing
9768-400: The space station, cislunar, and lunar landing missions. Once Kennedy's Moon landing goal became official, detailed design began of a command and service module (CSM) in which the crew would spend the entire direct-ascent mission and lift off from the lunar surface for the return trip, after being soft-landed by a larger landing propulsion module. The final choice of lunar orbit rendezvous changed
9879-431: The space vehicle's fins . This view was sufficiently ingrained in popular culture that in 1993, following a successful low-altitude test flight of a prototype rocket, a writer opined: "The DC-X launched vertically, hovered in mid-air ... The spacecraft stopped mid-air again and, as the engines throttled back, began its successful vertical landing. Just like Buck Rogers ." In the 2010s, SpaceX rockets have likewise seen
9990-448: The specification for another competition for spacecraft procurement bids in October 1961. On November 28, 1961, it was announced that North American Aviation had won the contract, although its bid was not rated as good as the Martin proposal. Webb, Dryden and Robert Seamans chose it in preference due to North American's longer association with NASA and its predecessor . Landing humans on
10101-474: The successful SpaceX CRS-8 mission, followed by SpaceX founder Elon Musk looking over Sheldon's old notebook then hiding it in a desk drawer. Apollo program The Apollo program , also known as Project Apollo , was the United States human spaceflight program carried out by the National Aeronautics and Space Administration (NASA), which succeeded in preparing and landing the first men on
10212-427: The technical details of the space program, and was put off by the massive financial commitment required by a crewed Moon landing. When Kennedy's newly appointed NASA Administrator James E. Webb requested a 30 percent budget increase for his agency, Kennedy supported an acceleration of NASA's large booster program but deferred a decision on the broader issue. On April 12, 1961, Soviet cosmonaut Yuri Gagarin became
10323-425: The technology with both of its stages on its fourth test flight . VTVL rockets are not to be confused with aircraft that take off and land vertically and use air for support and propulsion, such as helicopters and jump jets which are VTOL aircraft. The technology required to successfully achieve retropropulsive landings—the vertical landing, or "VL," addition to the standard vertical takeoff (VT) technology of
10434-515: The term speculative fiction to be used instead for those that are more "serious" or "thoughtful". Some scholars assert that science fiction had its beginnings in ancient times , when the line between myth and fact was blurred. Written in the 2nd century CE by the satirist Lucian , A True Story contains many themes and tropes characteristic of modern science fiction, including travel to other worlds, extraterrestrial lifeforms , interplanetary warfare, and artificial life . Some consider it
10545-925: The three-person Apollo command and service module directly to the lunar surface, on top of a large descent rocket stage, would require a Nova-class launcher, with a lunar payload capability of over 180,000 pounds (82,000 kg). The June 11, 1962, decision to use lunar orbit rendezvous enabled the Saturn V to replace the Nova, and the MSFC proceeded to develop the Saturn rocket family for Apollo. Since Apollo, like Mercury, used more than one launch vehicle for space missions, NASA used spacecraft-launch vehicle combination series numbers: AS-10x for Saturn I, AS-20x for Saturn IB, and AS-50x for Saturn V (compare Mercury-Redstone 3 , Mercury-Atlas 6 ) to designate and plan all missions, rather than numbering them sequentially as in Project Gemini. This
10656-470: The time of writing technologically impossible, extrapolating from present-day science...[,]...or that deal with some form of speculative science-based conceit, such as a society (on Earth or another planet) that has developed in wholly different ways from our own." There is a tendency among science fiction enthusiasts as their own arbiter in deciding what exactly constitutes science fiction. David Seed says it may be more useful to talk about science fiction as
10767-419: The vehicle at the correct angle. SpaceX also uses grid fins for attitude control during the landing of their Falcon 9 boosters. It can also be necessary to be able to ignite engines in a variety of conditions potentially including vacuum , hypersonic , supersonic , transonic , and subsonic . The additional weight of fuel, larger tank, landing legs and their deployment mechanisms will usually reduce
10878-430: The workability of the approach. In late 1961 and early 1962, members of the Manned Spacecraft Center began to come around to support LOR, including the newly hired deputy director of the Office of Manned Space Flight, Joseph Shea , who became a champion of LOR. The engineers at Marshall Space Flight Center (MSFC), who were heavily invested in direct ascent, took longer to become convinced of its merits, but their conversion
10989-478: Was 11.42 feet (3.48 m) tall, 12.83 feet (3.91 m) in diameter, and weighed approximately 12,250 pounds (5,560 kg). A cylindrical service module (SM) supported the command module, with a service propulsion engine and an RCS with propellants, and a fuel cell power generation system with liquid hydrogen and liquid oxygen reactants. A high-gain S-band antenna was used for long-distance communications on
11100-603: Was an upgraded version of the Saturn I. The S-IB first stage increased the thrust to 1,600,000 pounds-force (7,120 kN) by uprating the H-1 engine. The second stage replaced the S-IV with the S-IVB-200 , powered by a single J-2 engine burning liquid hydrogen fuel with LOX, to produce 200,000 pounds-force (890 kN ) of thrust. A restartable version of the S-IVB was used as the third stage of
11211-497: Was announced by Wernher von Braun at a briefing on June 7, 1962. But even after NASA reached internal agreement, it was far from smooth sailing. Kennedy's science advisor Jerome Wiesner , who had expressed his opposition to human spaceflight to Kennedy before the President took office, and had opposed the decision to land people on the Moon, hired Golovin, who had left NASA, to chair his own "Space Vehicle Panel", ostensibly to monitor, but actually to second-guess NASA's decisions on
11322-593: Was changed by the time human flights began. Since Apollo, like Mercury, would require a launch escape system (LES) in case of a launch failure, a relatively small rocket was required for qualification flight testing of this system. A rocket bigger than the Little Joe used by Mercury would be required, so the Little Joe II was built by General Dynamics / Convair . After an August 1963 qualification test flight , four LES test flights ( A-001 through 004 ) were made at
11433-536: Was chosen in Houston , Texas, on land donated by Rice University , and Administrator Webb announced the conversion on September 19, 1961. It was also clear NASA would soon outgrow its practice of controlling missions from its Cape Canaveral Air Force Station launch facilities in Florida, so a new Mission Control Center would be included in the MSC. In September 1962, by which time two Project Mercury astronauts had orbited
11544-404: Was influential on later filmmakers , bringing a different kind of creativity and fantasy . Méliès's innovative editing and special effects techniques were widely imitated and became important elements of the cinematic medium . 1927's Metropolis , directed by Fritz Lang , is the first feature-length science fiction film. Though not well received in its time, it is now considered
11655-480: Was known for its embrace of a high degree of experimentation, both in form and in content, and a highbrow and self-consciously " literary " or " artistic " sensibility . In 1961, Solaris by Stanisław Lem was published in Poland . The novel dealt with the theme of human limitations as its characters attempted to study a seemingly intelligent ocean on a newly discovered planet . Lem's work anticipated
11766-525: Was named after Apollo , the Greek god of light, music, and the Sun, by NASA manager Abe Silverstein , who later said, "I was naming the spacecraft like I'd name my baby." Silverstein chose the name at home one evening, early in 1960, because he felt "Apollo riding his chariot across the Sun was appropriate to the grand scale of the proposed program". The context of this was that the program focused at its beginning mainly on developing an advanced crewed spacecraft,
11877-662: Was the first crewed spacecraft to orbit another celestial body, and Apollo 11 was the first crewed spacecraft to land humans on one. Overall, the Apollo program returned 842 pounds (382 kg) of lunar rocks and soil to Earth, greatly contributing to the understanding of the Moon's composition and geological history. The program laid the foundation for NASA's subsequent human spaceflight capability and funded construction of its Johnson Space Center and Kennedy Space Center . Apollo also spurred advances in many areas of technology incidental to rocketry and human spaceflight, including avionics , telecommunications, and computers. The program
11988-408: Was the first of his three- decade -long planetary romance series of Barsoom novels , which were set on Mars and featured John Carter as the hero . These novels were predecessors to YA novels , and drew inspiration from European science fiction and American Western novels . In 1924, We by Russian writer Yevgeny Zamyatin , one of the first dystopian novels, was published. It describes
12099-403: Was the only component of the Apollo spacecraft to survive without major configuration changes as the program evolved from the early Apollo study designs. Its exterior was covered with an ablative heat shield , and had its own reaction control system (RCS) engines to control its attitude and steer its atmospheric entry path. Parachutes were carried to slow its descent to splashdown. The module
12210-423: Was the third US human spaceflight program to fly, preceded by the two-person Project Gemini conceived in 1961 to extend spaceflight capability in support of Apollo. Kennedy's goal was accomplished on the Apollo 11 mission when astronauts Neil Armstrong and Buzz Aldrin landed their Apollo Lunar Module (LM) on July 20, 1969, and walked on the lunar surface, while Michael Collins remained in lunar orbit in
12321-410: Was upgraded to 7,610,000 pounds-force (33,900 kN). The second and third stages burned liquid hydrogen; the third stage was a modified version of the S-IVB, with thrust increased to 230,000 pounds-force (1,020 kN) and capability to restart the engine for translunar injection after reaching a parking orbit .
