On September 20th, 2015 (August 8th, 2015 in the lunar calendar), China's first nanosatellite independently designed, developed and controlled by students was successfully launched. At 7: 01 on September 20th, 2015, the nano-satellite "Lilac-2" independently designed, developed and controlled by the student team of Harbin Institute of Technology was successfully launched at Taiyuan Satellite Launch Center. It is also the first nano-satellite independently designed, developed and controlled by college students in China. "Lilac-2" is the fifth satellite developed by Harbin Institute of Technology, weighing 12 kilograms, which is of positive significance for exploring the role of micro-nano satellites in future aerospace equipment and national economic construction. "At the moment of success, I was distracted for a few seconds, and suddenly remembered that our dream was questioned at the beginning. Now, it has been launched in just five years!" Wei Mingchuan, a doctoral student majoring in aerospace science and technology at Harbin Institute of Technology, is in charge of the overall design and measurement and control of the satellite. Talking about his feelings after success, he said: "Like-minded partners are rare wealth, experienced teachers are rare friends, and the most rare thing is a university that dares to support students' participation in aerospace projects." "Many people's graduation projects are related to the development of nanosatellites."
