Which of the following symptoms is likely to afflict an astronaut in space (a) swollen feet, (b) swollen face, (c) headache, (d) orientational problem?
Answer: (b),
(c), and (d)
(a) Legs hold the entire mass of a body in standing position
due to gravitational pull. In space, an astronaut feels
weightlessness because of the absence of gravity. Therefore, swollen
feet of an astronaut do not affect him/her in space.
(b) A swollen face is caused generally because of apparent
weightlessness in space. Sense organs such as eyes, ears nose, and
mouth constitute a person’s face. This symptom can affect an
astronaut in space.
(c) Headaches are caused because of mental strain. It can
affect the working of an astronaut in space.
(d) Space has different orientations. Therefore, orientational
problem can affect an astronaut in space.
