Space weather satellites in orbit 太空天气预测卫星进入轨道

The Soyuz rocket is successfully launched - at last

联盟号火箭终于发射成功

Two European satellites that will study the weather in space are finally orbiting the Earth four years after a first launch attempt ended in disaster when a carrier rocket blew up.

The satellites were lifted into space by a Soyuz rocket which took off from Kazakhstan in Central Asia on Sunday without a hitch.

The launch is the first stage in the key Cluster II programme.

The satellites, built by the European Space Agency (ESA), will look at interaction between the sun and the Earth.

Scientists hope to gain a better understanding of so-called "space weather," which can sometimes knock out weather or communication satellites orbiting the Earth.

两枚将探测太空天气情况的欧洲卫星终于进入绕地球运行轨道，4年前第一次发射时因运载火箭爆炸而失败。

这两枚卫星周日在中亚的哈萨克斯坦由联盟号火箭成功地运载升空。

这次发射是“星群二号”太空船计划的实施第一步。

这两枚欧洲宇航局建造的卫星将探测太阳和地球之间如何进行相互作用。

科学家们希望能够更好的了解所谓的“太空天气”，“太空天气”有时会对地球天气或对地球轨道上的通信卫星造成破坏。
