俄罗斯将一枚美国卫星送入太空

2012年10月14日
The first US satellite, the Vanguard satellite, went up in flames in a launch failure in December 1957. The US then authorized a back-up spacecraft mission, initiated unofficially a few years earlier by Wernher Von Braun. The spacecraft, named Explorer 1, was launched 31 January 1958 and was designed and built by a group of scientists from the University of Iowa, led by James Van Allen.

俄罗斯将美国一颗卫星送入太空。据俄罗斯航天局公布消息说,卫星发射顺利。两个月前,因运载卫星的“质子-M”火箭的发动机点火装置发生故障,导致发射失败,使俄罗斯付出了损失两颗卫星的严重代价。
