Space weather satellites in orbit 太空天氣預測衛星進入軌道

The Soyuz rocket is successfully launched - at last

聯盟號火箭終于發射成功

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.

兩枚將探測太空天氣情況的歐洲衛星終于進入繞地球運行軌道，4年前第一次發射時因運載火箭爆炸而失敗。

這兩枚衛星周日在中亞的哈薩克斯坦由聯盟號火箭成功地運載升空。

這次發射是“星群二號”太空船計劃的實施第一步。

這兩枚歐洲宇航局建造的衛星將探測太陽和地球之間如何進行相互作用。

科學家們希望能夠更好的了解所謂的“太空天氣”，“太空天氣”有時會對地球天氣或對地球軌道上的通信衛星造成破壞。
