The original Space Race primarily took place from the mid-1950s to the early 1970s, a period marked by intense competition between the United States and the Soviet Union. However, a new, more complex and multipolar space race is currently unfolding, characterized by the involvement of numerous state and private actors.

The first Space Race was an ideological and technological proxy battle during the Cold War, commencing with the Soviet Union's launch of Sputnik 1 in October 1957. This event challenged American technological superiority and ignited a fierce competition for firsts in space. Key milestones included Yuri Gagarin becoming the first human in space in April 1961, followed by the United States’ Apollo 11 lunar landing in July 1969. The motivations were predominantly national prestige, scientific advancement, and the demonstration of military and technological prowess, culminating in a period of détente symbolized by the Apollo-Soyuz Test Project in 1975.

The current era, often referred to as a "new" space race, began to accelerate in the early 21st century and is actively ongoing. Unlike its predecessor, this race involves a broader array of participants and motivations. Geopolitical intelligence signals show "Space" as a top connection by signal volume (79 tracked signals), underscoring its contemporary relevance. Major state actors include the United States (3 tracked signals from GeoGazet tracking) and China (6 tracked signals), both vying for leadership in lunar exploration, orbital dominance, and deep space missions.
