Effects of Gravity on Astronauts

What is the primary focus of scientists regarding gravity in the context of Mars missions today?

• Overcoming Earth's gravity to launch rockets

• Understanding how reduced gravity affects astronauts' physical condition

• Developing new propulsion systems

• 9.8 m/s²

How does the absence of gravity in space affect the distribution of body fluids in astronauts?

• Fluids move to the lower body

• Fluids remain evenly distributed

• Fluids shift toward the upper body and head

• Fluids evaporate

• 6 months

• 1 year

• 2 years

• 3 years

Why do astronauts have swollen, puffy faces in space?

• Due to increased blood pressure

• Due to fluid redistribution toward the upper body

• Due to lack of exercise

• Due to dehydration
