太阳轨道飞行器的主要科学目标是解决太阳物理学的核心问题：“太阳如何创造和控制日光层？”为了实现这一目标，航天器携带十个科学仪器（六个遥感仪器和四个现场仪器）的独特组合前往太阳系最内部区域，在其轨道部分距离太阳最接近 0.28 个天文单位。轨道倾角将逐渐增加，以便航天器到达更高的太阳纬度（在任务结束时达到34度），从而首次使对太阳极地区域的详细研究成为可能。本文介绍了航天器及其预定的绕太阳之旅。我们还讨论了在航天器的开发周期、仪器集成和测试过程中必须解决的主要工程挑战。
The main scientific goal of Solar Orbiter is to address the central question of heliophysics: 'how does the Sun create and control the heliosphere?' To achieve this goal, the spacecraft carries a unique combination of ten scientific instruments (six remote-sensing instruments and four in-situ instruments) towards the innermost regions of the Solar System, to as close as 0.28 AU from the Sun during segments of its orbit. The orbital inclination will be progressively increased so that the spacecraft reaches higher solar latitudes (up to 34 degrees towards the end of the mission), making detailed studies of the polar regions of the Sun possible for the first time. This paper presents the spacecraft and its intended trip around the Sun. We also discuss the main engineering challenges that had to be addressed during the development cycle, instrument integration, and testing of the spacecraft.
