Fifty-five years ago today, astronaut Yuri Gagarin made history, when he got into Soviet Vostok 1 spaceship capsule and launched into space. Yuri Gagarin became the first human in space. Reports praised Gagarin for his perfect flight, but in fact he didn’t pilot the Vostok capsule. Psychologists working with the Soviet Space Program were worried that exposure to weightlessness would impact the pilot’s decision-making faculties. And so, the pilot was effectively locked out of controlling his capsule.
