Active Tsinghua University student team behind the GRID nanosatellite gamma-ray-burst observation project. The official GRID site says the team is jointly supervised by Tsinghua faculty from Engineering Physics, Astronomy, and Computer Science, with more than 200 undergraduates participating. Students lead mission work from scientific concept and detector hardware through calibration, in-orbit observation, and data analysis; the site reports 13 satellite payloads launched by 2025 and five detectors operating in orbit.
