A Sputnik moment is a point where people realise that they are threatened of challenged and have to redouble their efforts to catch up. It comes from the time when the Soviet Union launched the first satellite, the Sputnik 1, and beat the USA into space.

“斯普特尼克”时刻是人们认识到自己受到威胁和挑战，必须加倍努力，迎头赶上的时刻。

它来自当时苏联发射的第一颗卫星的人造地球卫星“斯普特尼克”1号，此举击败了美国，率先进入太空。

Sputnik ，俄语，指人造卫星。
