1. The Missile at the Heart of Every Rocket
The foundational reality of the Space Race is that the technology propelling humans skyward and the technology designed to carry nuclear warheads across continents were, in their early forms, essentially the same. Both superpowers recruited German rocket engineers and seized German research after the Second World War, and both initially developed space launch vehicles as byproducts of ballistic missile programs. This meant that every Soviet or American space achievement was simultaneously a demonstration of strategic military reach. A nation that could put a satellite in orbit had already proved it could threaten any point on the globe.
Why it matters: Understanding this connection dissolves the romantic illusion that the Space Race was primarily about exploration. It was about deterrence, and space was simply the highest ground available.
