it home reported on september 5 that according to the china academy of launch vehicle technology (calt) today, on september 4, the new rocket long march 8a carrier rocket (referred to as "long march 8a rocket") developed by the calt successfully completed the launch site rehearsal mission at the no. 1 launch site of the hainan commercial space launch site.

the rocket academy stated in the announcement that this joint exercise was the first time that the rocket academy conducted rocket assembly and testing in the hainan assembly and testing plant, marking a further step forward in the rocket academy's layout in the hainan region. at the same time, this joint exercise was also the first time that the academy's active cryogenic rockets used the unified ground test, launch and control equipment independently developed, providing a valuable reference for the subsequent testing and launch missions of the academy's active cryogenic rockets.

cui shuo from the rocket academy said: "for this joint exercise, we adopted a new test and launch mode - the improved three-vertical test and launch mode, that is, the rocket body was transferred from the hainan assembly and test plant to the launch area in a vertical state with three modules: the core first stage booster assembly, the core second stage, and the satellite cover assembly, and then the hoisting and docking of each module was completed in the launch area."

the joint training officially started in mid-august, the refueling work was completed on september 3, and the arrow was lowered from the tower on september 4 and moved back to the hainan assembly and test plant from the launch area, thus completing the joint training mission successfully.

during this joint training mission, the coordination and matching of the chang zheng-8a rocket and the hainan commercial space launch site system (including the hainan general assembly and testing plant, the no. 1 launch station of the hainan commercial space launch site, the smart launch site system, the refueling and gas supply system, etc.) were well verified. the coordination and matching of the 5.2-meter fairing and the satellite-rocket joint operation with the launch site also passed the assessment smoothly. the joint training achieved its expected purpose.

in addition, a significant difference from previous models is that at the hainan commercial space launch site, all test operations on the rocket are completed by the type test team. this joint exercise also improved the organization and command, test operation and service support capabilities of the launch mission participants, laying a good foundation for the formal flight mission.

according to previous reports by it home, the long march 8a carrier rocket has a greater carrying capacity and higher carrying efficiency. it can provide a 700-kilometer sun-synchronous orbit and a gradient carrying capacity from 3 tons to 5 tons to 7 tons.

the rocket academy announced that in the future, the long march 8a rocket development team will combine the results of joint training to eliminate risks for the flight mission in advance and go all out to ensure the successful first flight of the long march 8a rocket at the end of the year.
