CCTV News: At present, the Shenzhou 19 astronaut crew has been in orbit for more than 80 days, the work is progressing smoothly, the physical and mental state is in good physical and mental state, and various scientific (trial) experiments in the space station are continuing to be carried out.

Complete a number of space science practice (trial) experiments in the fields of new space technologies and applications and microgravity physical sciences. In terms of orbital training, rendezvous and docking training, medical rescue on-orbital training, etc. were carried out. In terms of equipment maintenance in the space station, a number of tasks such as on-rail replacement of the space application fluid circuit circulation pump have been carried out. Survival outside the earth? This "black technology" is indispensable

In the field of new spatial technologies and applications, the crew carried out related work on the extraterrestrial survival artificial photosynthesis technology test project, used sampling tanks to sample the reactants inside the device, and completed downstream sample storage. Carry out related work on the test of artificial photosynthesis technology in extraterrestrial areas

This technology can simulate the natural photosynthesis of green plants through physical and chemical methods, utilize carbon dioxide resources in confined space and extraterrestrial atmosphere in situ, prepare oxygen and carbon-containing fuel, and provide important technical support for future human extraterrestrial survival and exploration. Disassemble and assemble the solid-liquid mesoscopic experimental unit of the fluid physics experiment cabinet

In the field of microgravity physics science, the crew disassemble and assemble the solid-liquid mesoscopic experimental unit of the fluid physics experiment cabinet, and complete the relevant work on the installation of the experimental sample tray. In addition, the crew also completed a number of operations such as cleaning of the experimental cavity sample of the container-free cabinet, replacing the experimental sample, and maintaining the electrode of the axis mechanism. Conduct rendezvous and docking training, medical rescue training, etc.

Last week, a number of on-orbit trainings were carried out one after another. The rendezvous and docking training is one of the professional technical training for astronauts during orbit. The crew uses the metacognitive training system to complete training content such as image recognition under different initial conditions. In addition, the crew carried out medical rescue in-orbit training and emergency life-saving in-orbit training to simulate emergency evacuation in the fire situation of the space station. Completed the replacement of the fluid circuit circulation pump in the space application.

In terms of equipment inspection and maintenance on the site, the crew carried out a number of tasks such as on-rail replacement of the fluid circuit circulation pump in the space application as planned. The space application fluid circuit system is an important thermal control subsystem for controlling and adjusting the space application load and supporting equipment temperature in each cabin section of the space station, ensuring the smooth progress of various space scientific (test) experiments.

Before the Spring Festival, the three astronauts will continue to complete all work with a full spirit. Let us look forward to it together!
