EXPERIMENTAL UNIT FOR DETERMINING BODY WEIGHT OF ASTRONAUTS AND LIGHT-WEIGHT OBJECTS IN ZERO-GRAVITY CONDITIONS

Сучасні інформаційні системи, 2022
The transition of an astronaut into zero gravity leads to a certain restructuring of the body, including the redistribution of fluid flows in it. The process of dehydration of the body is stimulated, the astronaut loses weight.
