NASA said it lost contact with the Solar Terrestrial Relations
Observatories1, known as the STEREO-B spacecraft, on Oct. 1, 2014, but that on Aug. 21, the Deep Space Network (DSN) established a link with the craft.
美国宇航局透露，他们在2014年10月1日与日地关系天文台STEREO-B号太阳探测卫星失联，而今年8月21日，深空探测网又与其重新取得联系。
Contact with the probe was lost after a
maneuver2 to try to prevent overheating of the ship's
antenna3.

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。
