CCTV News: Three astronauts from the Shen 19th Crew, Cai Xuzhe, Song Lingdong and Wang Haoze have been working and living in orbit for more than 100 days. Last week, the crew carried out actual space science experiments, rendezvous and docking on-orbit training, and equipment inspection and maintenance in the space station.
Research on the stress characteristics of bone muscles in orbit based on plantar pressure
In the field of aerospace medicine experiments, a number of experiments have been continuously carried out. Last week, the Shenniu Pier Group conducted a study on the stress of the bone muscles in the exercise group. Astronauts use muscle structure and function measurement, sole pressure collection, patch ultrasound and other equipment to collect plantar pressure, joint kinematic data and movement images of running and resistive movement under different load states during flight, and related muscle parameters to obtain the mapping relationship between parameters of different movement states and plantar pressure and the characteristics of muscle-tendon interaction change.
Research on protection technology for eye cranial pressure changes
What impact will the changes in eye cranial pressure of astronauts have on visual function during the "space business trip"? Three astronauts used visual function measuring instruments, hand-held optometry instruments, transorbital B-ultrasound and other equipment to complete multiple tests such as visual perception, far/near vision, diopter, eye axis and optic nerve sheath space.
Experimental projects in the field of microgravity physical sciences are carried out as planned
In addition, experimental projects in the field of microgravity physical sciences are carried out as planned. Last week, the astronaut completed a number of operations including disassembly and assembly of the experimental module of the fluid physics experiment cabinet, replacement of the space three-phase droplet migration load liquid bag, replacement of the combustion science experiment cabinet burner, replacement of the container-free cabinet experimental sample.
