The launch mission will be launched into orbit by the Long March 7 remote four carrier rocket carrying the Tianzhou-3 cargo spacecraft. Since the Tianzhou-3 rocket assembly arrived at the launch site on June 16, it has carried out preparations such as testing and inspection of various systems and general exercise of the whole system.
Mao Wanbiao, Deputy Director of xichang satellite launch center: Judging from the joint training of the whole navigation area, the measurement and control equipment in the whole navigation area is in good condition, the communication lines are smooth, and the conditions for refueling and launching are met. It should be said that our equipment and facilities are in good condition, and the whole test project of cargo spacecraft system, astronaut system, launch site system and rocket system has been completed, and the test status is qualified and the product quality meets the requirements. According to the latest meteorological consultation, the meteorological conditions meet the launch requirements.
The rocket system has entered the state preparation stage before launch, and the tank replacement and air tightness inspection of the whole system have been carried out, and the functions of the control system and measurement system on the rocket have been checked.
Ma Zhonghui, deputy chief designer of the Long March 7 rocket of the First Academy of Aerospace Science and Technology Group: The state of the cargo spacecraft and rocket launched in this mission was reviewed and confirmed, and some parts of the rocket were improved to enhance the robustness of the rocket; On the other hand, aiming at the problems existing in pre-launch and pre-launch, the refinement degree of pre-launch scheme and interpretation is optimized. At present, all functional checks have been completed and the conditions for launching and ignition are met.
The Tianzhou-3 cargo spacecraft launched this time is loaded with nearly 6 tons of materials and will rendezvous and dock with the core cabin of the space station independently and quickly to prepare for the subsequent Shenzhou-13 mission. At present, Tianzhou-2 in space has completed flying around, and the core module of the space station is waiting for Tianzhou-3 to arrive.
Lei, deputy director of the Tianzhou-3 cargo spacecraft system of the Fifth Academy of Aerospace Science and Technology Group: At present, the Tianzhou-3 cargo spacecraft system has completed comprehensive tests such as the vertical state of the launch area, cargo loading before launch, and launch state setting. The whole ship is in good condition and has launching conditions.
