How did technology change american life in the 1970’s?

Many significant electronic and computer inventions that continue to play a vital role in society today date back to the 1970s. The American public was greatly impacted in various ways due to the affordability, efficiency, and novelty of these inventions. In Space exploration, the continuation of the Space Race implemented the improved relationship between the US and the USSR. Détente also led to an official of the Space Race. As a result, American culture was greatly influenced by the significant scientific and technological advancements in the 1970s particularly in computer and electronics technology.
In the Space Race, the 1970s was a period of reduced tensions due to the improved relation between the US and the Soviet Union. In addition, the accomplishment of the first lunar landing in 1969 had set a clear victory for the US. However, the Space Race continued in the 1970s as its significance started to subside due to the confrontation of many difficult circumstances such as the Vietnam War and the energy crisis. One of the elements of space exploration that the US government was interested in was the development of re-usable space shuttles for scientific research and experimentations. Even though such a shuttle was not fully developed until 1978, the Skylab created by NASA since 1973, served as a space station for scientists to study celestial bodies and perform experiments. In brief, a reusable space shuttle was an ultimate US goal for Space Race in the 1970s due to this period of détente. (Chaikin)
As the decade progressed, the Apollo missions continued lunar explorations. However, unlike the Apollo missions in most of the 1960s, the missions placed a more heavy emphasis on scientific exploration.
