Tsinghua initiated, 4 universities and 4 satellites, successfully launched!

At 11:14 on January 15, the “Tiange Plan” cooperation group initiated by Tsinghua University, and 4 satellite payloads from 4 universities were successfully launched! Among them, the GRID-05B satellite payload of Tsinghua University is carried on the Changguang satellite MF02A07. The Long March-2D carrier rocket was launched from the Taiyuan Satellite Launch Center and successfully entered the predetermined orbit, the satellite was in good condition, and the launch was a complete success!

The Tiange student teams of each university, as the main force, completed the development and calibration of satellite payloads based on the technical data open and shared by Tsinghua University in the “Tiange Program” cooperation group, including: GRID-06B (carrying the Changguang satellite MF02A04 star), GRID-08B (carrying the TY-28 star of the Sky Telescope Research Institute), jointly developed by Nanjing University and Sichuan University. GRID-07 of Beijing Normal University (carrying the TY-28 star of the Celestial Instrument Research Institute).

Since 2020, Tsinghua University has held the Tiange Project Summer Camp every year, inviting experts, scholars and veterans of the Tiange Project to teach students about all aspects of satellite payload detectors and scientific analysis of gamma-ray bursts. In the past three years, the tutors of the four universities have also cooperated in-depth to provide a platform for cross-school and interdisciplinary exchange and scientific exploration for the students of the Tiange student team of each school.

It is expected that the four payloads successfully launched this time will carry out joint observations with multiple space grid payloads that have been launched in orbit before, and continue to observe and analyze gamma-ray bursts, solar activity and pulsars in orbit.

Previously, the “Tiange Project” released the first scientific results in December 2021: GRB 210121A, the first cosmic gamma-ray burst observed by the GRID-02 satellite payload, and the relevant scientific results were published in the journal The Astrophysical Journal, and the Tiange team of Nanjing University and the Tiange team of Tsinghua University completed the processing and physical analysis of the Tiange observation data. This is the first scientific observation of gamma-ray bursts officially published by the “Tiange Program”, and it is also the first case of scientific discovery and publication of scientific discoveries and papers in the international nanosatellite gamma-ray burst detection project.

With the successful launch of GRID-03B and GRID-04 in 2022, the “Tiange Program” cooperation group has entered the stage of multi-star stable scientific observation, and 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 scientific satellites, hoping to get more valuable observation results after the ground gravitational wave detector is upgraded and started again.

Initiated by Tsinghua University in 2016, the “Tiange Project” is a space science project with undergraduate student teams as the main body, and also a basic science talent training project at the intersection of science and engineering, with the main scientific goal of finding gamma-ray bursts and other high-energy astrophysical transient sources in association with gravitational waves and fast radio bursts.

At present, the “Tiange Program” cooperation group has been jointly participated by more than 20 universities and research institutes, including Tsinghua University, Nanjing University, Sichuan University, Beijing Normal University, Institute of High Energy of the Chinese Academy of Sciences, and Space Science Center of the Chinese Academy of Sciences, and the first batch of scientific data has been transferred to the National Space Science Data Center for open sharing with the scientific community.

With the support of the Youth League Committee and the Research Institute of Tsinghua University, the team of Tsinghua University’s “Tiange Project” continued to explore the cultivation of top-notch talents in basic science of “integration of science and education”, under the guidance of Zeng Ming, associate professor of the Department of Engineering and Physics, Feng Hua, professor of the Department of Astronomy, Zeng Zhi, researcher of the Department of Engineering and Physics, Tian Yang, assistant researcher of the Department of Engineering and Physics, and Associate Professor Xu Benda. The student team of Tsinghua University’s “Tiange Program” is also supported by the Tsinghua-Kunshan Student Innovation and Entrepreneurship Talent Training Cooperation Agreement.
