我国计划向日地L5点发射“羲和二号”探测器

Group 1 - The core point of the article is that China plans to launch the "Xihe-2" solar probe to the Sun-Earth L5 point between 2028 and 2029, which will enhance solar observation capabilities [1][2] - The "Xihe-2" probe is designed with a launch mass of approximately 1600 kilograms and will carry multiple payloads including a spectral magnetometer and high-energy solar telescope [1] - The probe will have a design life of 7 years, allowing it to remain at the L5 point with minimal fuel consumption, providing a stable platform for long-term solar observation [1] Group 2 - Currently, over 70 solar probes have been launched by humanity, with most located along the Sun-Earth line, and none have been stationed at the Sun-Earth L5 point [2] - The "Xihe-2" probe will take about 800 days to reach the L5 point, where it will provide a new perspective for measuring solar magnetic fields and activities [2] - The mission aims to establish a complete three-dimensional physical model of solar eruptions and improve China's space weather forecasting capabilities [2]
