Space Age

The Soviet launch opens the era

October 4, 1957 was not an arbitrary day in the armistice but the midpoint of the International Geophysical Year (1957–1958). In that international project, which drew 67 countries and reopened scientific exchange between East and West, the USSR put an 83.6 kg metal sphere into low Earth orbit without warning. The opening of the Space Age was therefore a product of the Cold War and of international cooperation at once. The United States had announced its own satellite plans, the two countries entered a record race, and the US caught up about four months after the launch. The Soviet Union went on to take the first artificial satellite, the first human spaceflight (April 12, 1961), the first woman in space (1963), and the first spacewalk (March 18, 1965).

Sergei Korolev led the design of those spacecraft, yet in his lifetime he was named only as the Chief Designer. In a system of competing design bureaus under state secrecy, his identity could not have been made public.

Where the starting line falls

Using 1957 as the starting point is a choice of standard, not a fact. Robert Goddard's liquid-fuel launch in 1926 and the German V-2's suborbital flight in June 1944 came earlier, but neither reached orbit and the V-2 launches were secret. Because a rocket capable of orbit could also serve as an intercontinental ballistic missile, some commentators argue that the orbital standard was adopted precisely for that military dual use. Both the United States and the Soviet Union absorbed German missile technology and personnel after the war, and securing a means to deliver nuclear weapons was one of the early drivers of the competition.

What the planned economy mobilized, and its limits

Where the United States consolidated its effort under NASA in 1958, the Soviet space program remained divided among several design bureaus headed by Korolev and others, often under the Ministry of General Machine-Building. That a country with a rural majority could monopolize the early records rested on free education and a planned economy's capacity to concentrate resources on one field. At the same time the records were propaganda for state power, and scientific results were its by-product.

Mid-career, the Soviet lunar landing program was kept from public acknowledgement and shrank, partly from internal debate over its necessity and partly because of Korolev's death in 1966. The US space budget rose almost 500 percent between 1961 and 1964, but funding fell on both sides once the record race ended. The Apollo-Soyuz test flight of 1975 turned competition into cooperation, and in the 1990s funding dropped sharply as the remaining space structures collapsed with the USSR.

Competition, cooperation, competition again

In the 1970s the Soviet Union flew other countries' cosmonauts under the Intercosmos program. The Salyut station line led to Mir, operated from 1986 to 2000, and after the dissolution of the USSR Roscosmos continued the work. Soviet assets from experimental technologies and military satellites to the International Space Station remain in use.

As commercial launches spread in the 2000s and defense against hazardous near-Earth objects such as asteroids and comets became a task, journalists in the 2020s spoke of a "New Space Age." The Cold War duopoly and today's multinational, commercial configuration share a name but not a character.

Where the era ends is likewise disputed. One account closes it in 1975 with the start of US-Soviet cooperation; another treats the later national and private ventures as a differently characterized phase, drawing the boundary at the turn of the 1980s/1990s.
