第一颗人造卫星进入太空

First Satellite Launched Into Space

The USSR launches Sputnik 1, the first artificial satellite to orbit the earth.

In 1957, the world was surprised to see the Soviets launch the first satellite into orbit, with most expecting the USA to be the first to do so.

The satellite, namedSputnik 1, transmitted a simple radio signal back to earth for 21 days and remained in orbit for a further 6 months.

The USA responded to this great technological achievement by making the conquest of space a top national priority.

This marked the beginning of the "space race".

这颗名为伴侣号的人造卫星21天后将简单的无线电信号传回地球，之后仍然在轨道上停留了6个月。

美国通过将征服太空作为首要目标回应苏联的这一伟大科技成果。

这标志着“太空竞赛”的开始。
