The conversation between human and AI assistant.
Why don't they generate artificial gravity in ISS by rotating the ship on its axis, to generate centrifugal force equivalent to gravity?
How is the lack of gravity affecting the health of astronauts in space?
The lack of gravity can have a number of negative effects on astronauts' health. These include muscle and bone loss, vision problems, and immune system suppression. To minimize these effects, astronauts exercise for several hours a day and take supplements to maintain their bone density.
