This article is a summary of the 1970s in science and technology.
The 1970s in science and technology reached its height with the ambitious Voyager Program, which sent the Voyager 1 and Voyager 2 uncrewed expeditions to several of the outer planets in the Solar System. The program also included a Voyager Golden Record with the spaceships in hopes of presenting aspects of life on Earth to intelligent alien life forms. The record contained pictures and other data about human beings and other living beings on earth. It also had an assortment of music from across cultures. [1]
Coupled with the zenithal achievements of the Voyagers was the end of NASA's Apollo lunar spacecraft program, with the final flight, Apollo 17, [2] in 1972. The Apollo–Soyuz and Spacelab programs ended in 1976, and there would be a five-year hiatus in American crewed spaceflight until the flight of the Space Shuttle. [3] [4] The Soviet Union developed vital technologies involving long-term human life in free-fall on the Salyut and later Mir space stations.
The 1970s witnessed an explosion in the understanding of solid-state physics, driven by the development of the integrated circuit and the laser. The evolution of the computer produced an interesting duality in the physical sciences at this period — analogue recording technology had reached its peak and was incredibly sophisticated. However, digital measurement and mathematical tools, now becoming cheaper (though still out of reach for the general public) allowed discrete answers and imaging of physical phenomena, albeit at a low resolution and a low bandwidth of data. This tendency was to reach its peak in 1982, though the period 1974–1982 represents the 'period of dichotomy' in the metrication of the sciences.
Deep understanding of physics became important in the 1970s. At CERN, the Irs proton collider and the Super Proton Synchrotron started operation in this decade, and Stephen Hawking developed his theories of black holes and the boundary-condition of the universe.
The biological sciences, spurred by social concerns about the environment and life, gained tremendous detail. The elucidation of molecular biology, bacteriology, virology and genetics achieved their modern forms in this decade. Discrete quantum interactions within living systems became amenable to analysis and manipulation. Genetic engineering became a commercially viable technology.
The changes and attitude of social concern regarding science in the 1970s was addressed by Warren Weaver, who said that "Scientific theories cannot be rigidly deterministic." [5]
The birth of modern computing was in the 1970s. The world's first general microprocessor, the Intel 4004, came out in November 1971. The C programming language was developed early in the decade and the Unix operating system was rewritten into it in 1973. With "large-scale integration" possible for integrated circuits (microchips) rudimentary personal computers began to be produced along with pocket calculators. Notable home computers released in North America of the era are the Apple II, the TRS-80, the Commodore PET, and Atari 400/800 and the NEC PC-8001 in Japan.
The availability of affordable personal computers led to the first popular wave of internetworking with the first bulletin board systems. In 1976, Cray Research, Inc. introduced the first supercomputer, the Cray-1, which could perform 230,000,000 calculations per second. Supercomputers designed by Cray continued to dominate the market throughout the 1970s. The 1970s was also the beginning of the video game era. Atari established itself as the dominant force in home video gaming, first with its home version of the arcade game Pong and later in the decade with the Atari 2600 console (originally called the "VCS", or Video Computer System). By 1979, the scene was set for the Golden Age of Arcade Games.
The 1970s were also the start of fiber optics. In 1970 Corning Glass announced that it had created a glass fiber so clear that it could be used to communicate pulses of light. Soon after GTE and AT&T began experiments to transmit sound and image data using fiber optics, and transformed the communications industry. After 1973 both the United States and Europe turned away from the large and heavy mainstream automobiles, and towards lightweight, fuel-efficient and environmentally-conscious vehicles, already beginning to be produced by Japan. The Lotus Esprit was an example of a 1970s super car, producing high performance from a small engine. The Volkswagen Golf GTI of 1974 made the concept of a performance hatchback part of automotive mainstream thinking, though it had many precedents.
The United States lagged badly in the development of compact and fuel-efficient vehicles, a side effect of industrial inexperience on the part of the manufacturers in Detroit. Two giants of the industry, GM and Ford both produced vehicles that fell drastically short of customer desires and economic demands; in the case of GM the Vega and for Ford the Pinto. Automotive historians have also described the period as 'the era of poor quality control', and manufacturers internationally produced vehicles that have since become by-words for poor technological integration.
Notably, the 1970s saw the introduction in the automotive field of novel technologies, particularly from Japan and Germany, that would begin to mature in the 1990s and 2000s as viable alternative propulsion sources, such as hybrid vehicles, Stirling engines, as well as solar-electric and pure-electric vehicles.
The integration of the computer and robot, particularly in Japan, saw unprecedented improvements in mass-produced automotive quality. Japanese advanced lightweight, fuel efficient and environmentally-conscious vehicles dramatically increased in demand, and such cars as the Honda Civic and the Toyota Corolla became some of the most popular and iconic vehicles of the 1970s. Japanese manufacturers dramatically made their presence felt in international markets during the decade.
During the 1970s, microwave ovens experienced a surge in popularity as price and size decreased rapidly towards the end of the decade. Cassette tapes continued to surge in popularity after their introduction in the 1960s. JVC's VHS and Sony's Betamax waged a videotape format war as the primary recording and video devices beginning in 1976, but by the end of the decade VHS had become the dominant format. Also introduced to the home market was the Laserdisc, the first optical disc format used primarily for high quality video.
The Ames Research Center (ARC), also known as NASA Ames, is a major NASA research center at Moffett Federal Airfield in California's Silicon Valley. It was founded in 1939 as the second National Advisory Committee for Aeronautics (NACA) laboratory. That agency was dissolved and its assets and personnel transferred to the newly created National Aeronautics and Space Administration (NASA) on October 1, 1958. NASA Ames is named in honor of Joseph Sweetman Ames, a physicist and one of the founding members of NACA. At last estimate NASA Ames had over US$3 billion in capital equipment, 2,300 research personnel and a US$860 million annual budget.
The George C. Marshall Space Flight Center (MSFC), located in Redstone Arsenal, Alabama, is the U.S. government's civilian rocketry and spacecraft propulsion research center. As the largest NASA center, MSFC's first mission was developing the Saturn launch vehicles for the Apollo program. Marshall has been the lead center for the Space Shuttle main propulsion and external tank; payloads and related crew training; International Space Station (ISS) design and assembly; computers, networks, and information management; and the Space Launch System. Located on the Redstone Arsenal near Huntsville, MSFC is named in honor of General of the Army George C. Marshall.
In engineering, a heat shield is a component designed to protect an object or a human operator from being burnt or overheated by dissipating, reflecting, and/or absorbing heat. The term is most often used in reference to exhaust heat management and to systems for dissipating frictional heat. Heat shields are used most commonly in automotive and aerospace.
Draper Laboratory is an American non-profit research and development organization, headquartered in Cambridge, Massachusetts; its official name is The Charles Stark Draper Laboratory, Inc. The laboratory specializes in the design, development, and deployment of advanced technology solutions to problems in national security, space exploration, health care and energy.
Vance DeVoe Brand is an American naval officer, aviator, aeronautical engineer, test pilot, and NASA astronaut. He served as command module pilot during the first U.S.-Soviet joint spaceflight in 1975, and as commander of three Space Shuttle missions.
BESM-6 was a Soviet electronic computer of the BESM series.
George Michael Low was an administrator at NASA and the 14th president of the Rensselaer Polytechnic Institute. Low was one of the senior NASA officials who made decisions as manager of the Apollo Spacecraft Program Office in the Apollo program of crewed missions to the Moon.
The Space Age is a period encompassing the activities related to the space race, space exploration, space technology, and the cultural developments influenced by these events, beginning with the launch of Sputnik 1 on October 4, 1957, and continuing to the present.
As a federal agency, the National Aeronautics and Space Administration (NASA) receives its funding from the annual federal budget passed by the United States Congress. The following charts detail the amount of federal funding allotted to NASA each year over its history to pursue programs in aeronautics research, robotic spaceflight, technology development, and human space exploration programs.
The Canberra Deep Space Communication Complex (CDSCC) is a satellite communication station, part of the Deep Space Network of NASA's Jet Propulsion Laboratory (JPL), located at Tidbinbilla in the Australian Capital Territory. Opened in 1965, the complex was used for tracking the Apollo Lunar Module, and along with its two sister stations at Goldstone, California and Madrid, Spain is now used for tracking and communicating with NASA's spacecraft, particularly interplanetary missions. Its DSS-43 antenna is the only antenna on Earth that can send commands to Voyager 2. It is managed in Australia by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) for NASA’s Space Communications and Navigation program (SCaN) at NASA Headquarters in Washington, D.C.
The Apollo Applications Program (AAP) was created as early as 1966 by NASA headquarters to develop science-based human spaceflight missions using hardware developed for the Apollo program. AAP was the ultimate development of a number of official and unofficial Apollo follow-on projects studied at various NASA labs. However, the AAP's ambitious initial plans became an early casualty when the Johnson Administration declined to support it adequately, partly in order to implement its Great Society set of domestic programs while remaining within a $100 billion budget. Thus, Fiscal Year 1967 ultimately allocated $80 million to the AAP, compared to NASA's preliminary estimates of $450 million necessary to fund a full-scale AAP program for that year, with over $1 billion being required for FY 1968. The AAP eventually led to Skylab, which absorbed much of what had been developed under Apollo Applications.
Spaceflight began in the 20th century following theoretical and practical breakthroughs by Konstantin Tsiolkovsky, Robert H. Goddard, and Hermann Oberth, each of whom published works proposing rockets as the means for spaceflight. The first successful large-scale rocket programs were initiated in Nazi Germany by Wernher von Braun. The Soviet Union took the lead in the post-war Space Race, launching the first satellite, the first animal, the first human and the first woman into orbit. The United States would then land the first men on the Moon in 1969. Through the late 20th century, France, the United Kingdom, Japan, and China were also working on projects to reach space.
The Crew Return Vehicle (CRV), sometimes referred to as the Assured Crew Return Vehicle (ACRV), was a proposed dedicated lifeboat or escape module for the International Space Station (ISS). A number of different vehicles and designs were considered over two decades – with several flying as developmental test prototypes – but none became operational. Since the arrival of the first permanent crew to the ISS in 2000, the emergency return capability has been fulfilled by Soyuz spacecraft and, more recently, SpaceX's Crew Dragon – each rotated every 6 months.
The following outline is provided as an overview of and topical guide to space exploration.
Skylab B was a proposed second US space station similar to Skylab that was planned to be launched by NASA for different purposes, mostly involving the Apollo–Soyuz Test Project, but was canceled due to lack of funding. Two Skylab modules were built in 1970 by McDonnell Douglas for the Skylab program, originally the Apollo Applications Program. The first was launched in 1973 and the other put in storage, while NASA considered how to use the remaining assets from Apollo.
NASA spin-off technologies are commercial products and services which have been developed with the help of NASA, through research and development contracts, such as Small Business Innovation Research (SBIR) or STTR awards, licensing of NASA patents, use of NASA facilities, technical assistance from NASA personnel, or data from NASA research. Information on new NASA technology that may be useful to industry is available in periodical and website form in "NASA Tech Briefs", while successful examples of commercialization are reported annually in the NASA publication Spinoffs. The publication has documented more than 2,000 technologies over time.
The National Aeronautics and Space Administration is an independent agency of the U.S. federal government responsible for the civil space program, aeronautics research, and space research. Established in 1958, it succeeded the National Advisory Committee for Aeronautics (NACA) to give the U.S. space development effort a distinct civilian orientation, emphasizing peaceful applications in space science. It has since led most of America's space exploration programs, including Project Mercury, Project Gemini, the 1968–1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. Currently, NASA supports the International Space Station (ISS) along with the Commercial Crew Program, and oversees the development of the Orion spacecraft and the Space Launch System for the lunar Artemis program.
As the coalition of Bay Areas counties predicted when it lobbied for the creation of Moffett Federal Airfield in the late 1920s, the base's research program and facilities catalyzed the development of numerous private technology and aerospace corporations, among them Lockheed Martin and the Hiller Aircraft Corporation.
