Core Viewpoint - China plans to launch the "Xihe-2" solar probe to the Sun-Earth L5 point between 2028 and 2029, marking a significant advancement in solar observation capabilities [1][3] Group 1: Project Overview - The "Xihe-2" project was officially initiated, following the successful launch of the first solar probe, "Xihe," in October 2021, which has been operational beyond its expected lifespan [1] - "Xihe-2" will conduct three-dimensional observations of the Sun from a new perspective, as it will not orbit the Earth like "Xihe" [1][3] Group 2: Technical Aspects - The L5 point is one of five gravitational balance points between the Earth and the Sun, allowing "Xihe-2" to maintain a stable orbit with minimal energy consumption, designed for a lifespan of up to 7 years [3] - The probe will enable precise measurements of solar magnetic fields and activities, contributing to the establishment of a comprehensive three-dimensional physical model of solar eruptions [3] Group 3: Scientific Significance - "Xihe-2" will provide a new observational perspective, allowing for advanced warnings of solar activities such as solar flares and coronal mass ejections, potentially giving Earth a preparation time of four to five days [3]
