Fifty years ago today, on October 4, 1957, the world’s first artificial satellite was launched by the former Soviet Union, marking the start of the Space Age.
Called Sputnik, meaning „fellow traveler“, it was about the size of a basketball, weighed only 83 kilograms, and took about 98 minutes to orbit the Earth while transmitting a series of rapid beeps. Then, on November 3rd, 1957, the Soviets launched Sputnik II, carrying a heavier payload including a dog named Laika. On January 31, 1958, the United States entered the space race by launching Explorer I, a satellite that discovered the magnetic radiation belts surrounding the Earth. The Sputnik launch also led to the creation of NASA on October 1st, 1958. Since then, humans have walked on the moon, created the International Space Station, sent robots to Mars and dispatched numerous spacecraft to explore the universe.
