The Cold War was getting icy, and the threat of nuclear war loomed large, but on this day, the world took a giant leap towards peace. The Soviet Union, the United States, and the United Kingdom came together to sign the Outer Space Treaty, a groundbreaking agreement that banned the deployment of nuclear weapons in space and limited the use of celestial bodies like the Moon for peaceful purposes only. This historic treaty ensured that the final frontier wouldn't become the next battleground, and paved the way for future space exploration and cooperation.
