China’s space industry has reached a significant milestone with the successful completion of the integration and testing phase for the new Long March 8A carrier rocket, also known as the Chang 8A Rocket. According to official information from the China Academy of Launch Vehicle Technology (CALT), the rocket was successfully launched during a rehearsal at the Hainan Commercial Space Launch Site on September 4, marking a significant step forward for China’s space capabilities.
Firsts Achieved in the Chang 8A Rocket Program
The Chang 8A Rocket’s maiden flight is a first for the rocket institute in several aspects. Firstly, it is the first time that the institute has conducted the total assembly and testing of a rocket in the Hainan total assembly and testing workshop. This development signifies a further expansion of China’s space infrastructure in the Hainan region.
Secondly, it is the first time that the institute has used domestically developed unified ground measurement and control equipment for its operational cryogenic rockets. This advancement provides valuable reference for the testing and launch of subsequent cryogenic rockets.
Key Features of the Chang 8A Rocket
The Hainan Commercial Space Launch Site’s first launch position, constructed by the Special Vehicle Company of the rocket institute, is a critical component for the site’s ability to conduct launches. It serves as an essential facility for ensuring the success of national-level tasks.
The Hainan total assembly and testing workshop is equipped with two pulse-type production lines and three vertical test stations for comprehensive testing. By integrating traditional factory testing with some of the testing conducted at the launch site, the process has been streamlined, resulting in improved measurement and launch efficiency.
The rehearsal for the Chang 8A Rocket utilized an improved three-vertical measurement and launch mode. This involved transporting the rocket’s core first stage, second stage, and payload fairing modules in a segmented vertical state from the Hainan total assembly and testing workshop to the launch area, where the modules were then hoisted and connected.
Rehearsal and Testing Process
The rehearsal began in mid-August and was completed on September 3, with the rehearsal rocket being lowered from the tower and returned to the Hainan total assembly and testing workshop on September 4. The rehearsal was successfully completed.
During the rehearsal, the coordination and compatibility between the Chang 8A Rocket and the Hainan Commercial Space Launch Site’s systems, including the Hainan total assembly and testing workshop, the first launch position of the Hainan Commercial Space Launch Site, the intelligent launch site system, and the refueling and gas supply system, were well-verified. The 5.2-meter fairing and spacecraft joint operations and compatibility with the launch site were also successfully tested, achieving the expected results.
Expected Maiden Flight by Year-End
The Chang 8A Rocket is scheduled for its maiden flight by the end of the year. This launch will further solidify China’s position in the global space industry and demonstrate the nation’s commitment to advancing its space capabilities.
The successful completion of the Chang 8A Rocket’s integration and testing phase is a testament to China’s advancements in rocket technology and its dedication to expanding its space infrastructure. As the nation continues to make strides in space exploration, the Chang 8A Rocket will play a crucial role in carrying out future missions and expanding China’s presence in the cosmos.
