“太阳轨道器(”Solar Orbiter)是欧空局“宇宙愿景”计划最早发射的中级科研项目,大约在2017年发射,它也是2003年启动的“人类与日共存”(ILWS)国际空间合作计划最后一颗卫星,旨在研究太阳表面和大气,对发生在太阳系核心的高能过程进行近距离观测。“太阳轨道器”由欧空局19国与美国航宇局共同合作,任务的总预算约为10亿美元,其中包括提供并集成10台科学仪器,已及卫星的发射和运行费用。欧空局各成员国航天局负责研制观测仪器,NASA将负责发射相关事宜。2012年4月,欧空局授予阿斯特里姆英国公司一份价值3.9亿美元的合同,建造该探测器。
“Solar Orbiter is the earliest mid-level research project launched by ESA ” Universe Vision “and will be launched around 2017. It is also the” Man and the Sun live together “launched in 2003 ILWS) The last satellite of the International Space Cooperation Program aims to study the surface of the sun and the atmosphere and to observe closely the high-energy processes occurring in the core of the solar system. The ”Solar Orbiter", co-operated with NASA by 19 countries in ESA, has a total mission budget of about 1 billion U.S. dollars, including the provision and integration of 10 scientific instruments, as well as satellite launch and operation costs. NASA Member States Space Agency is responsible for the development of observation equipment, NASA will be responsible for launch related issues. In April 2012, ESA awarded Astral UK a $ 390 million contract to construct the probe.
