Sputnik I was a polished metal sphere of 23 inches in diameter, with four external radio antennas to broadcast radio pulses. Launched at the 5th Tyuratam range from what is now known as the Baikonur Cosmodrome in Kazakhstan, the satellite completed each orbit in 96.2 minutes at a speed of about 18,000 miles per hour. Sputnik I transmitted on 20.005 and 40.002 MHz for 21 days until the batteries ran out. After three months, 1440 completed orbits and having travelled a distance of about 43 miles, Sputnik burned up on 4 January 1958 as it re-entered the earth's atmosphere. Sputnik's success triggered the Space Race, a chapter of the Cold War between the West and the Soviet Union. It provided scientists with valuable information, marking the beginning of a new era of technological and scientific developments.
