Can someone explain why astronauts train for space in swimming pools, do they expect to find fish up there?

Question

I never understood the whole reason of why train in a swimming pool, i spend lots of time in swimming pools so i guess i'm ready for outer space.

Answer 1

maybe the pressure under water could compare to the pressure in outer space.

Answer 2

it's the best we can do for simulating weightlessness.

they've been doing it since the 1960s. it's hardly a new thing.

Answer 3

It simulates weightlessness.  In space, pushing against a wall or an object creates an equal & opposite force on you...in a pool, you can simulate that. On dry land, your weight braces you against such forces.  

Answer 4

HAHAHAHAHA!

Pools filled with water are the closest thing to zero gravity on Earth!

Answer 5

If you spent as much time in pools as you suggest, you would already know that it's as close as we can come on Earth to a weightless environment. Astronauts in pools are weighted to give them zero buoyancy, so they more or less 'hover' in the tanks. It's also a good way to test working in a space suit, where you're dependent upon it to breathe.

Answer 6

training in pools means they stabilise there water movement in turn there is any sort of water bodies

Answer 7

Yes. Fish, sharks, and possibly Atlantis.  

Answer 8

Swimming pools help to simulate weightlessness.

Answer 9

They are simulating weightlessness. They are not just playing Marco Polo, they are practicing doing work where everything is weightless. It isn't a perfect simulation, but as close as can be had on Earth.

Answer 10

What, do you find fish in your swimming pool?

The use of a large pool gives the astronauts a chance to practice their tasks under a condition similar to the microgravity they will experience in orbit.  By carefully counterbalancing their equipment, they float in the water just as they would float in space.

I'm surprised you would have to ask such a question -- it seems so intuitively obvious to the casual observer . . .

Answer 11

Water is the closest simulation we have of weightlessness.

Answer 12

austronauts train in pools because you are lighter in pools and there is no gravity hardly in pools, just like outer space..please choose me mas a best answer i have never been choosen before!!

Answer 13

There is neutral buoyancy in space, and neutral buoyancy can be achieved in a pool.

Answer 14

It's the only way on Earth's surface to simulate microgravity. You're not one of those who thinks that NASA has zero gravity chambers, are you?

Answer 15

It's the best approximation of 0 or reduced gravity we can recreate over long periods of time.
