What does sputnik mean?
Sputnik is an artificial satellite associated above all with the Soviet Union’s pioneering space program. Sputnik 1, launched in 1957, was the first artificial satellite to orbit Earth, and its radio signals made the beginning of the space age unmistakable to audiences worldwide. The name came to represent the rapid development of space technology and the intense scientific and political rivalry that followed between the Soviet Union and the United States. In broader cultural use, Sputnik can mean an artificial satellite generally, especially when recalling the early years of space exploration. It is also used figuratively in phrases such as “before Sputnik,” referring to a period before the beginning of the space age. The word is chiefly historical today, but it remains a concise symbol of a decisive technological achievement and of the extraordinary public impact of orbital science.

Etymology of sputnik
The English word Sputnik comes from Russian спутник (sputnik), meaning “satellite” and literally “fellow traveller.” Russian спутник is related to путь (putʹ), meaning “path” or “way,” reflecting the idea of accompanying someone on a journey. The term was borrowed into English during the 1950s for the Soviet space program, when Sputnik 1 and its successors made orbital flight internationally famous.
