why the cold war was called the cold war

This timeline shows the twenty-year competition between the two nations. The space race between the United States (US) and the Soviet Union (USSR) was a remarkable time in history with many far-reaching achievements in science, space exploration, and technology.

The space race produced groundbreaking efforts to launch artificial satellites space probes of the Moon, Venus, and Mars, and human space voyages in low Earth orbit and lunar missions. The technological advantages required for such power were seen as necessary for national security and political superiority. Both sides were aided by German missile technology and scientists from their missile programme. The space race has its origins in the nuclear arms race between the two nations following the Second World War. The competition began on 2 August 1955, when the Soviet Union responded to the US announcement of their similar intent to launch artificial satellites. The pursuit for both was the domination of space flight technologies. The space race was a 20th Century struggle between two nation-states, the Soviet Union (USSR) and the United States (US).
