On June 11, China Science and Technology Aerospace announced the successful completion of the test mission of the first-stage propulsion system of the Lijian-2 liquid carrier rocket. This pivotal ground test, conducted during the Lijian-2 project's development phase, rigorously validated the rocket's key technologies. It has laid a solid power foundation for the upcoming maiden flight, which will launch the Qingzhou prototype test cargo spacecraft, thereby ensuring the rocket's flight reliability and stability. The test took place at the newly constructed Liquid Propulsion System Test Center of China Science and Technology Aerospace, whose timely completion and commissioning have been instrumental in supporting the rocket's development.
