Imagine sailing across the stars, your only guide a tool invented centuries ago. That's exactly what happened during the Apollo 8 mission.

In the age of space exploration, where computers were the brains of every mission, astronauts had to prepare for the worst. What if the computer failed? Enter the sextant, a relic from the age of sail. This ancient tool, more at home on a pirate ship than a spaceship, was crucial in guiding Apollo 8 around the Moon.

Astronauts used the sextant to measure angles between stars and the lunar horizon. It was like finding your way in a vast desert using distant mountains. These measurements helped them pinpoint their location in the infinite void of space, ensuring they didn't drift into the endless cosmos.

In a world obsessed with the new, it's a reminder that the old can still hold power. Could the answers to future space travel lie in the tools of our past?
