Before silicon chips, the most powerful computers were human beings
In short: Explore how NASA transitioned from room-sized mechanical machines to modern supercomputers. This video traces the evolution of computing power that made space exploration possible, highlighting a pivotal era when 'computers' were actually people.
In the early days of space exploration, the most advanced computers were massive mechanical devices that occupied entire rooms but offered limited processing power. To overcome these limitations, NASA relied on "human computers"—predominantly women—who performed the complex calculations necessary for early missions.
Today, the legacy of those human calculations lives on in high-performance supercomputers at facilities like NASA's Ames Research Center. These machines have evolved from mechanical gears to essential tools used for tracking global climate patterns, designing safer spacecraft, and exploring deep space.
