On September 5, 2025, 10:34 AM (Beijing Time) , China successfully launched the Shiyan-29 satellite into its pretest orbit using a Long March-3C carrier rocket with the Yuanzheng-1 (Expedition-1) upper stage from the Xichang Satellite Launch Center. The satellite’s solar panels have deployed normally, and the mission has achieved complete success!

The Shiyan-29 satellite is primarily designed for space environment detection and related technology experiments. It was developed under the overall management of the Innovation Academy for Microsatellites of the Chinese Academy of Sciences(IAMCAS). Northwestern Polytechnical University (NPU) served as the undertaking institution for one of the satellite’s core payloads — the on-board real-time processing system.
Professor Zhang Yanning of NPU served as the chief designer of the on-board real-time processing system for the Shiyan-29 satellite and other satellites. After years of dedicated efforts, her team has overcome significant challenges and achieved a series of critical breakthroughs in theoretical research, key technologies, and engineering development related to space environment detection and processing. The team completed this crucial development task on schedule and with high quality, strongly supporting the successful implementation of these satellite missions. The consecutive success in high-frequency launch missions not only demonstrates NPU’s maturity and reliability in theoretical, methodological, and technical expertise, as well as its efficient engineering capabilities, but also highlights the team’s sense of responsibility, collaborative spirit, and strong capability in making hard-core contributions to national missions.
