Summary
The Tianlu-1 satellite is a Chinese spacecraft designed for scientific research focused on atmospheric studies. It was launched on January 17, 2025, from the Jiuquan Satellite Launch Center using a Long March 2D launch vehicle. The satellite measures 0.7 meters in length and 1 meter in diameter, with a mass of 100 kilograms.
The Tianlu-1 is equipped with advanced scientific instruments for limb-sounding detection of the middle and upper atmosphere. These instruments can measure temperature, atmospheric composition, density, and wind field vectors, providing high-resolution vertical profiles of the atmosphere. The satellite is powered by solar panels and uses X-band frequencies for data transmission.
The mission duration is not publicly disclosed, but the satellite is designed to conduct comprehensive atmospheric studies and collect data to improve weather forecasting, space weather research, and climate change studies. The Tianlu-1 has successfully entered its preset orbit and begun collecting atmospheric data, marking a significant milestone in China's space program.
