SOHO是太阳与太阳大气层观测站，是ESA和NASA之间进行国际合作的项目，目的是研究太阳从深部核心到外日冕和太阳风。
SOHO于1995年12月2日发射升空。SOHO航天器由一个由主要承包商Matra Marconi Space（现为EADS Astrium）领导的工业团队在欧洲制造，由ESA全面管理。 SOHO上的十二种仪器是由欧美科学家提供的。国际文书联盟中有九个由欧洲首席研究员（PI）领导，三名由美国的PI领导。大型工程团队和来自许多机构的200多名共同研究人员为PI的仪器开发以及操作和数据分析的准备工作提供了支持。 NASA负责发射，现在负责任务运营。形成NASA的深空网络的世界各地的大型无线电天线用于数据下行链路和命令。任务控制位于马里兰州的戈达德太空飞行中心。
SOHO, the Solar & Heliospheric Observatory, is a project of international collaboration between ESA and NASA to study the Sun from its deep core to the outer corona and the solar wind. SOHO was launched on December 2, 1995. The SOHO spacecraft was built in Europe by an industry team led by prime contractor Matra Marconi Space (now EADS Astrium) under overall management by ESA. The twelve instruments on board SOHO were provided by European and American scientists. Nine of the international instrument consortia are led by European Principal Investigators (PI's), three by PI's from the US. Large engineering teams and more than 200 co-investigators from many institutions supported the PI's in the development of the instruments and in the preparation of their operations and data analysis. NASA was responsible for the launch and is now responsible for mission operations. Large radio dishes around the world which form NASA's Deep Space Network are used for data downlink and commanding. Mission control is based at Goddard Space Flight Center in Maryland.
