  On the early morning of January 18th,the Tianzhou-7 cargo spacecraft successfully docked with the aft port of the Tianhe core module of the space station.On the evening of the 17th,the Long March 7 Yao-8 carrier rocket carrying the Tianzhou-7 cargo spacecraft was ignited and launched from the Wenchang Space Launch Site in China.What aerospace technologies are providing support for the Tianzhou-7 cargo spacecraft in this mission?

  At 22:27 on January 17th,the Long March 7 Yao-8 carrier rocket carrying the Tianzhou-7 cargo spacecraft ignited and launched from the Wenchang Space Launch Site in China.About 10 minutes later,the spacecraft successfully separated from the rocket and entered the designated orbit.Afterwards,the spacecraft's solar panels were successfully deployed and the launch was a complete success.Photo by Xinhua News Agency reporter Li Gang
  The new generation of"conductors"assist in safer launch
  The Tianzhou-7 cargo spacecraft is subjected to the test of the huge noise generated by rocket engines during launch.In order to ensure the successful launch mission,the spacecraft needs to undergo noise testing during the ground development phase.
  The"examination room"for assessment is a giant"reverberation room"built by the Fifth Academy of Aerospace Science and Technology Group,while the"examination paper"is a"choir"composed of excellent"conductors"of the noise test control system,who command low,medium,and high frequency speakers,imitating the noise emitted by rockets during takeoff and takeoff.
  In this"exam",the Tianzhou-7 cargo spacecraft handed in a full score answer sheet.This is also the"debut"of the new generation noise test control system in manned space missions.This system has undergone more than 30 years of development and its performance has reached the international advanced level.
  The entire launch process of the integrated measurement and control system can be fully controlled
  How to fully"control"the status of Tianzhou-7 in the vast space like tracking logistics information?
  According to experts from China Electronics Technology Corporation(CETC),the new generation of integrated measurement and control system used in the Tianzhou-7 mission can operate automatically.Similar to the autopilot of an aircraft,it can allocate computing resources on demand across the entire network based on task occupancy and equipment health,improving resource utilization.
  This measurement and control system is developed by China Electronics Technology Corporation(CETC)and can operate multiple measurement and control,data transmission modes simultaneously.It is compatible with different signal forms,different frequency points,and multiple targets,achieving orbit measurement,telemetry and remote control,and data transmission of spacecraft.
  Optimization and upgrading of driving mechanism for flexible and robust"motion joints"
  At present,the space station has been in a combination form for a long time,and the force and heat environment faced by cargo spacecraft is relatively complex and variable,which puts higher requirements on the reliability of the"motion joint"-driving mechanism of cargo spacecraft.
  After the spacecraft docks at the space station,the driving mechanism located at the connection between the solar wings and the spacecraft's propulsion module is an important component that provides energy transmission for the spacecraft.It adjusts the angle of the solar wing to achieve the maximum range of sunlight shining on the solar wing,thereby ensuring power generation efficiency.
  In the development process of the Tianzhou-7 cargo spacecraft,researchers from the Eighth Academy of Aerospace Science and Technology Group optimized and upgraded the driving mechanism to further improve its driving ability and reliability.This"motion joint"can better control the solar wing to complete tracking,capture and other actions,and has stronger adaptability to working conditions such as solar wing deployment,aircraft orbit change,docking,parking,and return braking.
