太阳立体探测任务设想

Solar space exploration is of great importance in the study of cutting-edge solar physic problems and space weather forecasting applications. Over the past 60+ years of exploration activities, people have made a series of significant achievements, but still left many root problems that need to be solved. Solar stereo exploration can overcome the limitation of single-view observation, and access to omni-directional & multi-element physical data, thus contributing to the solution of major scientific problems in solar physics. This paper first introduces four scientific objectives (the Sun’s internal structure and the origin of solar magnetic fields, the mechanism of solar activities, full heliospheric space weather effects of solar activities and space weather forecasting models), then explains the space layout and system composition of the solar stereo exploration mission and the probe’s system engineering, and ends up with the mission’s payload configuration and its major technical indicators. By orbiting the ecliptic and omni-dimensional exploration of polar regions, solar stereo exploration realizes solar detection from five views, equipped China with the ability to detect the Sun in all directions and will provide high-quality data for scientific research and space weather forecasting. These achievements will promote Chinese solar physics research to a global frontier academic position and greatly improve the performance on Chinese space weather forecast. Therefore, we could realize a leapfrogged development in the field of solar exploration and give strong support for China’s innovation-driven development strategy and the construction of a strong sci-tech nation.
