Solar magnetic fields and related solar magnetic activities dominate the heliospheric environments from the near-Earth space, to the interplanetary space, and up to the interstellar boundary. The polar magnetic fields of the Sun and its dynamic processes are especially vital in the aspects of manifesting the internal dynamo of the Sun, and shaping magnetic fields in the heliosphere. But so far, high quality observations of solar polar region is quite limited, especially the accurate polarization and Doppler imaging.
The Chinese spacecraft of Solar Polar-orbit Observatory (SPO) has been designed to directly image the solar polar regions in an unprecedented way by traveling in a large solar inclination angle (larger than 80 degree) and a small ellipticity. Based on multi-band remote-sensing and in-situ easurements, the SPO will focus on: the origin of solar magnetic activity cycle and high-speed solar wind, and providing the necessary, complete, and self-consistent initial and boundary conditions for creating a data-driven global heliospheric numerical model that serves as the foundation for space weather prediction.
In this presentation, we will give an overview of SPO, such as its scientific objectives, satellite, payloads, and mission plan.
