The self-developed satellite payloads developed by students from four colleges and universities including Tsinghua University were successfully launched

　　China News Service, Beijing, January 18 (Reporter Gao Kai) The reporter learned from Tsinghua University that at 11:14 on January 15, 4 satellite payloads of 4 universities in the "Tiange Project" cooperation group initiated by Tsinghua University were successfully launched.

　　Among them, the GRID-05B satellite of Tsinghua University was carried on the MF02A07 star of the Changguang Satellite, and was launched from the Taiyuan Satellite Launch Center by the Long March 2D carrier rocket, and successfully entered the predetermined orbit. The satellite was in good condition and the launch was a complete success.

　　According to reports, there are 4 Tiange satellite payloads of 4 universities in the "Tiange Project" cooperation group that were launched at the same time. Based on the technical data of the satellite, the development and calibration of satellite payloads have been completed, including: GRID-06B (carrying Changguang satellite MF02A04 star) jointly developed by Nanjing University and Sichuan University, GRID-08B (carrying Tianyi Research Institute TY-28 star), Beijing Normal University's GRID-07 (equipped with Tianyi Research Institute TY-28 star).

　　It is expected that the four payloads successfully launched this time will conduct joint observations with multiple Tiange payloads that have been launched in orbit before, and conduct continuous on-orbit observation and analysis of gamma-ray bursts, solar activities, and pulsars.

　　Previously, the "Tiange Project" released the first batch of scientific results in December 2021: the GRID-02 satellite payload observed the first cosmic gamma-ray burst event GRB210121A, and related scientific results were published in the journal "The Astrophysical Journal" (The Astrophysical Journal) Journal), the Tiange team of Nanjing University and the students of the Tiange team of Tsinghua University completed the processing and physical analysis of Tiange observation data.

This is the first officially published scientific observation result of a gamma-ray burst by the "Tiange Project", and it is also the first gamma-ray burst event in which scientific discoveries and papers have been published in similar nanosatellite gamma-ray burst detection projects in the world.

　　With the successful launch of GRID-03B and GRID-04 in 2022, the "Tiange Project" cooperation group has entered the stage of multi-satellite stable scientific observation. In the next 2-3 years, it will continue to launch satellite payloads to build a constellation observation network, and continue to Carry out in-depth cooperation and collaborative data analysis with GECAM gravitational wave gamma-ray burst science satellite, etc., and expect to obtain more valuable observation results after the ground gravitational wave detector is upgraded and turned on again.

　　"Tiange Project" was launched by Tsinghua University in 2016. It is a space science project with undergraduate student teams as the main body. Horse storms and other high-energy astrophysical transient sources are major scientific objectives.

　　At present, more than 20 universities and research institutes including Tsinghua University, Nanjing University, Sichuan University, Beijing Normal University, Institute of High Energy Technology of Chinese Academy of Sciences, and Space Science Center of Chinese Academy of Sciences have participated in the "Tiange Project" cooperation group, and the first batch of scientific data has been submitted to the country. The Space Science Data Center is open and shared by the scientific community.
