Three Shenzhou 13 astronauts returned to the Beijing Aerospace Flight Control Center for key technical interpretation
At 0:44 today, the Shenzhou 13 manned spacecraft was successfully separated from the space station Tianhe core module, and the Shen 13 crew traveled for a total of 183 days, refreshing the record of the space stay time of Chinese astronauts in a single mission. Follow the reporter to see what has been done this morning?
CCTV reporter Wang Yan: I am now at the Beijing Aerospace Flight Control Center, and I am next to Zou Xuemei, deputy chief engineer of the space station mission of the Beijing Aerospace Flight Control Center. Let's first combine the introduction of the large screen behind us, the left screen can see the approximate flight position of the space station now, and the other two screens, the state of the Shenzhou XIII spacecraft above, and the status of the three astronauts of Shenzhou XIII below. Now that we see that their state is relatively static, please ask Zou Xuemei to interpret for us what work they have done since this morning, especially this morning?
Zou Xuemei, deputy chief engineer of the space station mission of the Beijing Aerospace Flight Control Center: The astronauts have completed the separation, evacuation, and independent flight calibration of the spacecraft and the space station in the early hours of this morning. The ground measured the orbit of the entire spacecraft and compared the calculation of the return control parameters in combination with the meteorological conditions of the landing site. The astronauts mainly carried out some state settings before the return of the return module and the orbital module, and at present, the three of them have returned to the return capsule in place, closed the door of the return module, and completed the airtightness inspection of the pressure suit in the cabin.
CCTV reporter Wang Yan: What are the key technical links in the process of this rapid return plan? Next, we must complete the posture adjustment and separation work between the various modules of the Shenzhou 13 spacecraft, what are the key technical nodes?
Zou Xuemei, deputy chief engineer of the space station mission of the Beijing Aerospace Flight Control Center: This time the implementation is a five-circle return plan, and the whole return work rhythm is much faster than before. During this period, we will complete a series of work such as the determination of the orbit of the spacecraft, the calculation of control parameters and the comparison of relevant data. The follow-up spacecraft should complete the separation from the orbital module, and then carry out automatic control before return, separate after the control is completed, re-enter the atmosphere, and then carry out the return search work.
