The space age officially began on October 4,1957,when the Soviet Union launched the modest 185-pound Sputnik Ⅰ,the first artificial satellite to orbit the earth.The following month,Russians successfully launched the 1,100-pound Sputnik Ⅱ,which carried into space the globe,a female dog named Laike,who suffocated on the sixth day of the flight because of a failure in the internal temperature of the craft.But the satellite itself orbited the earth for 162 days and burned up on re-entering the earth`s atmosphere.The United States,playing second fiddle to its superpower rival,orbited its first satellite,Explorer Ⅰ,on January 31,1958.It was a lightweight,18-pound craft,carrying not animals but sensitive instruments to study the intense bands of energy in space known as the Van Allen radiation belts.Within the next fifteen years man had gone to the moon.searching beneath its dry and dusty soil for sign of life [there were none],and begun probing more distant space of the solar system.One physicist,Werner Von Braun,played a crucial role in this odyssey,especially in planning the bold scheme for the 1969 landing of three Americans on the moon.

官方记载的太空时代开始于1957年10月4日,当日苏联发射了最初的185磅重的Sputnik I（卫星1号）,这是第一个绕地球运转的人造卫星.次月,俄国人成功发射了1100磅重的Sputnik II（卫星2号）,它将一条名叫Laike的狗带入了太空.这只狗在太空飞行的第6天由于卫星内部温度出现问题而被闷死了,但卫星本身却环绕地球走了162天并在回返地球大气过程中烧毁.在与其超级大国对手对决中处于下风的美国于1958年1月31日发射了其首个人造卫星Explorer Ⅰ（探索者1号）,这是一个轻量级卫星,只有18磅重,未携带动物,但带了用于研究太空中被称作Van Allen辐射带的能量密集带的精密仪器.在之后的15年内人类飞上了月球,在其干燥砂性的月表之下寻找生命的迹象（当时没有）,并开始探索太阳系中更遥远的空间.物理学家Werner Von Braun在这一冒险探索（特别是在谋划1969年三位美国人登月的大胆计划）中扮演了关键角色.
