一 | (ECNS) -- A student satellite team from Harbin Institute of Technology successfully launched its self-developed Lilac-3 satellite into orbit, marking a milestone for a young team involved in independent satellite development. The satellite was launched aboard a Gravity-1 Y4 carrier rocket from waters near Shanghai at 10:54 a.m. on July 22. Telemetry data was successfully received at 11:41 a.m., confirming the mission’s success. Lilac-3 features an ultra-flat disk-shaped design, with its main body measuring less than 5 centimeters in thickness. The design allows satellites to be stacked more efficiently during launches and is expected to support future low-orbit constellation deployment. When the project began, about 70% of team members were undergraduates, with an average age of 22. Most had no previous experience with complete satellite engineering projects and learned new technologies during the development process. After the first Lilac-3 failed to enter orbit due to a launch failure earlier this year, the team rebuilt the satellite within three months, improving its performance and adding new experimental tasks. Founded in 2012, this team is the first university student team in China to independently complete satellite design, development and mission management. Lilac-3 is the fourth satellite successfully launched by the team. (By Intern Liu Shuangjing, Zhang Dongfang) 。
