Tsinghua University's "TianGe Project" GRID-11B satellite payload was successfully launchedTsinghua News Network, November 11th. At 12:03 on November 11th, the GRID-11B satellite payload of the "Tiange Project" jointly developed by Tsinghua University and Sichuan University was carried on the Changguang Satellite Jilin-1 Platform 02A03 satellite and launched from the Jiuquan Satellite Launch Center by the Lijian-1 Yao-5 carrier rocket. It successfully entered the predetermined orbit, the solar sails were smoothly deployed, the satellite worked normally, and the launch mission was a complete success.GRID-11B is the 10th satellite payload successfully launched by the "Tiange Project". At present, the "Tiange Project" has taken the lead in realizing multi-satellite on-orbit scientific observations among similar micro-nano satellite gamma-ray burst detection scientific projects in the world, and has initially realized the nanosatellite scientific constellation. As a new member of the "Tiange Project" constellation, the launch of GRID-11B will further improve the constellation's networking scientific observation capabilities. Previously, on June 22, the GRID-10B satellite payload of the "Tian Ge Project" was carried on the CATCH-1 satellite of the Institute of High Energy Physics of the Chinese Academy of Sciences and was successfully launched from the Xichang Satellite Launch Center by the Long March 2C carrier rocket. GRID-11B and GRID-10B have undergone a number of major upgrades based on existing functions, adding charged particle detectors; adding a high-throughput mode and supporting on-orbit adaptive mode switching, which will enable the Tian Ge payload to achieve 24-hour all-day observation, greatly improving Tian Ge's scientific research output capacity.The "Tian Ge Project" student team undertook the assembly, calibration and debugging of the GRID-11B satellite payload, and the Star Test Future from the "Tian Ge Project" student team provided the data acquisition unit technical solution for the satellite payload.The "Tian Ge Project" was initiated by Tsinghua University. It is a space science project with undergraduate student teams as the main body, and it is also a basic science talent training project that crosses science and engineering disciplines. Its main scientific goal is to find gamma-ray bursts associated with gravitational waves and fast radio bursts and other high-energy astrophysical transient sources. At present, the "Tian Ge Project" cooperation group has more than 20 universities and research institutes participating in the cooperation, including Tsinghua University, Nanjing University, Sichuan University, Beijing Normal University, Institute of High Energy Physics of the Chinese Academy of Sciences, and Center for Space Science of the Chinese Academy of Sciences.With the support of the Youth League Committee of Tsinghua University and the "Light Chasing Plan" of the Research Institute, the "Tian Ge Project" continues to explore the cultivation of top talents in basic science with "integration of science and education". It is jointly guided by Professor Zeng Ming of the Department of Engineering Physics, former Professor Feng Hua of the Department of Astronomy, Researcher Zeng Zhi of the Department of Engineering Physics, Associate Professor Xu Benda, Lecturer Han Wentao of the Department of Computer Science, and Associate Researcher Tian Yang of the Department of Engineering Physics. The student team of the "Tian Ge Project" of Tsinghua University has also received support from the Tsinghua-Kunshan Student Innovation and Entrepreneurship Talent Training Cooperation Agreement.The next generation "Tian Ge Project 2.0: MeV Gamma Detection Nanosatellite Constellation (MASS Nuclear Astrophysics Spectral Line Survey)" is being promoted in an orderly manner as a major project of Tsinghua University's 2030 Innovation Action Plan. The first GRID-MASS gamma-ray burst detection and Compton imaging whole star will be launched in 2025.
