Sputnik 1 was the first man-made satellite to go around the Earth.[1] It was made by the Soviet Union.[1] It was launched on 4 October 1957 at Baikonur Cosmodrome.[1] It orbited (went around) the Earth for three months.[1] It did 1,440 orbits of the Earth during this time. It went down into Earth's atmosphere on 4 January 1958 and burned up.[1]
The United States was very surprised when the Soviet Union sent Sputnik 1 into space. It did not want to fall behind. So, it began spending more money on science and education.[2] This was when the Space Race between the Soviet Union and the United States began.
Etymology [change]
The word Sputnik comes from the Russian Спутник, literally travelling companion. It is pronounced IPA: ['sput.nik] or IPA: ['sput.nık], not 'spʌt.nık.[1][3]
