About this Episode
On October 4th, 1957, the Soviet Union launched Sputnik 1, the first artificial satellite to orbit Earth. This momentous event marked the beginning of the Space Age and sparked the Space Race between the United States and the Soviet Union.
Sputnik 1 was a small, spherical satellite, measuring only 58 centimeters (23 inches) in diameter and weighing approximately 83.6 kilograms (184 pounds). It was equipped with four external radio antennas and transmitted radio signals back to Earth, which could be detected by amateur radio operators around the globe.
The satellite orbited Earth every 96 minutes, traveling at a speed of about 29,000 kilometers per hour (18,000 miles per hour). Its elliptical orbit took it as close as 228 kilometers (142 miles) and as far as 947 kilometers (588 miles) from Earth's surface.
The success of Sputnik 1 caught the United States off guard and fueled fears that the Soviet Union had surpassed them in technological capabilities. This event galvanized the American public and government to invest heavily in science education and space technology, ultimately leading to the creation of NASA and the race to put a human on the Moon.
Sputnik 1's battery lasted for only 22 days, after which the spacecraft continued to orbit silently for two more months. It finally fell back into Earth's atmosphere and burned up on January 4th, 1958, having completed 1,440 orbits around our planet.
The legacy of Sputnik 1 lives on, as it paved the way for countless satellite missions, space exploration endeavors, and technological advancements that have transformed our understanding of the universe and our place within it. So, the next time you gaze up at the night sky, remember the little satellite that started it all on this very day back in 1957!
