After losing communication with a space probe two years ago, NASA says it
has reestablished contact.
在和一颗卫星失联两年之后，美国宇航局宣布和它重新取得了联系。
NASA said it lost contact with the Solar Terrestrial Relations
Observatories, 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.
据美国宇航局的消息，于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，深空探测网于今年8月21日又与其重新取得联系。
Contact with the probe was lost after a maneuver to try to prevent
overheating of the ship’s antenna.
失联是在一次防止STEREO-B天线过热的操作之后发生的。
STEREO-B is the sister craft to STEREO-A, both of which were launched in
2006 to study the sun and space weather. 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 corona.
STEREO-B是STEREO-A的伙伴卫星，这两颗卫星均于2006年发射，用来研究太阳和空间气候。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。
STEREO-A is reportedly working normally.
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 sensors are operating after two years.
美国宇航局称，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。
Both spacecraft are located on the other side of the sun from earth.
两颗卫星都位于太阳背对地球的那一面上。
