　　STEREO-B is the sister craft to STEREO-A, both of which were launched in 2006 to study the sun and space weather.

　　STEREO-B是STEREO-A的姊妹卫星，这两颗卫星均于2006年发射，用来研究太阳和空间气候。

　　The spacecrafts have contributed greatly to the understanding of coronal mass ejections, a bubble of super-heated gas and charged particles blasted into space from the sun's upper atmosphere, the corona⁴. STEREO-A is reportedly working normally.

　　这两颗卫星在研究日冕物质喷射（从太阳高空大气日冕层喷射到宇宙空间中的超高温气体和带电粒子）方面有很大的贡献。据报道，STEREO-A卫星一直运转正常。

　　NASA said it will now have to test STEREO-B to see how instrumentation and other sensors⁵ are operating after two years.

　　美国宇航局声称，现在将会对STEREO-B卫星进行测试，以检查仪器仪表和其他传感器在两年之后的运行情况。
