CTOnews.com, November 1 (Xinhua)-- Xihe is China's first solar exploration satellite. Since its launch in 2021, it has produced super-400TB high-quality scientific data and a series of original scientific research achievements.

CCTV released a video today, which was made for the first time by combining all-day spectral scanning imaging, showing the spectacular outbursts on the solar surface observed by Xi he.

According to reports, China is currently carrying out the demonstration of the solar-terrestrial L5 solar exploration project "Xihe No.2". At present, it is initially planned to launch in 2026, and a man-made detector will be launched to L5 points in the sun and earth for the first time, opening the era of three-dimensional solar exploration in China.

CTOnews.com Note: L5, the fifth Lagrangian point, is about 150 million kilometers from the earth. At this point, the satellite remains basically stationary relative to the earth and the sun.

Officials say the launch of a satellite to detect L5 points in the sun and earth, combined with near-earth observation, can realize the three-dimensional reconstruction of solar activity.

The L5 point of the sun and earth is an international exploration blank, and it is of great scientific significance and engineering feasibility to carry out exploration in this area. Combined with near-earth observation, the three-dimensional reconstruction of solar activity can be realized at L5, which provides key information for revealing the physical mechanism of solar bursts, and the solar activity facing the earth can be observed four or five days in advance. real-time tracking of Earth-facing solar bursts brings a revolutionary breakthrough to space weather forecasting.

On October 14, 2021, the Xihe satellite was successfully launched from the Taiyuan Satellite launch Center. The full name of "Xihe" is "Solar H α Spectral Exploration and double Super platform Science and Technology Test Satellite". The successful launch of "Xihe" broke the history of no special satellite for solar exploration in China.
