The QB50 project is "an International Network of 50 double Cube Sats for multi-point, in-situ, long-duration measurements in the lower thermosphere and re-entry research". There are 23 countries and region participated in the QB50 Project. 38 Cube Sats were developed and launched. Among them, four Cube Sats developed by Chinese universities were sent to orbit(Three were deployed from the International Space Station, and one was launched by the Polar Satellite Launch Vehicle, PLSV). They are Aoxiang-1(Northwestern Polytechnical University, the Asia coordinator), Lilac Sat-1(Harbin Institute of Technology), NJUST-2(Nanjing University of Science and Technology) and NUDTsat(National University of Defense Technology). Through the development of the QB50 Project, Chinese researchers and students got in touch with the concept of Cube Sat and gained experience of international scientific cooperation. A lot of students took part in the assembly, integration, and test of spacecraft, which is helpful to the training of space talents. Now, many universities and institutes have the capabilities to develop Cube Sats and the subsystems independently.展开更多
