Do astronauts grow taller in space?

Answer 1

Yes, you can become 2 inches taller in space; but will return to normal height when back on earth.

Gravity compresses the soft cartilage in your spine as you sit and stand up all day; so you are taller in the morning than at any other time in the day. This resets at night when you lie down, so no gravity would mean no compression.

Answer 2

In order to grow food, you need air, water, soil, and reasonable temperature.

-- Mercury . . . No air or water, unreasonably high and low temperatures.

-- Venus . . . . No water, unreasonably high temperature

-- Earth . . . . . Everything just right in many places

-- Mars . . . . . No water, very little air, drastic temperature changes

-- Jupiter . . . . Poisonous air, no water or soil, unreasonably low temperature

-- Saturn . . . . Poisonous air, no water or soil, unreasonably low temperature

-- Uranus . . . . Poisonous air, no water or soil, unreasonably low temperature

-- Neptune . . . Poisonous air, no water or soil, unreasonably low temperature

-- Pluto . . . . . . No air or water, unreasonably low temperature

Answer 3

Yes, astronauts can temporarily grow taller in space due to the lack of gravity compressing their spines. However, they return to their normal height once back on Earth and gravity begins to compress their spines again.

Answer 4

Without gravity pulling down on the spine, it is natural that the spine will relax and the astronaut will be taller - until returning to earth.

Answer 5

This is for the same reason that people are slightly taller in the morning. The spine stretches slightly when it doesn't have pressure on it.

Answer 6

no gravity.

Gravity compresses your spinal cord up to 2 inches. When you sleep, your spine flattens out and you will grow overnight

Answer 7

Actually, we do. Astronauts have been recorded to be more than three inches taller due to spinal stretching in the absence of gravity.
