Sputnik - /Sputnik/- satellite

  The word 'Sputnik' literally means 'travelling companion'. But in 1957 this word got another meaning. On october 4, 1957 for the first time a man-made object went into space to orbit the earth. It was launched by the Soviet Union and called 'Sputnik'. It immediately became a world sensation. Amateur radio operators  could catch its signals and people round the Planet were listening to its 'beep' sounds. The satellite weighed about 83 kg and  was 58 cm in diameter. It went around the Earth in 96 minutes. The word "sputnik" entered many world languages.
