The Soviet Union shocked the world by launching Sputnik 1, a beach-ball-sized satellite, into Earth's orbit, marking a historic milestone in space exploration. This technological marvel, weighing just 83 kg, was carried by an R-7 rocket from the Baikonur Cosmodrome in Kazakhstan. Sputnik 1, meaning "fellow traveler" in Russian, broadcast a continuous beep-beep signal, which was detected by radio telescopes around the globe, confirming its presence in space. This groundbreaking achievement sparked a space race between the US and the USSR, igniting a new era of scientific innovation and international competition.
