Under the Surface
Water is used for many things . You drink it . You use
it to wash things . You swim in it . But , did you know
water is used to train astronauts ?
There is very little gravity in space . That means that
astronauts float around in their spacecraft . This makes
them feel weightless . Training in water helps them get
ready for what it feels like to be in space .
Astronauts are not the only people who train in water .
Athletes train in water , too . Water can also be used
to help people get better after they have been injured.
And water can help people with
chronic conditions , such as
arthritis .

An athlete swims in a pool .

Staying Neutral
You may have noticed that objects that are heavy on land
seem lighter when they are in the water . This is because
they are more buoyant in water than they are on land .
That makes some things that are hard to do on land much
easier in water . In the pool , you can lift your friends with
ease . You can even float !
The feeling you have when you are in water is almost
what it feels like to be in space . In fact , some astronauts
train for space in water . They train in labs that have large
pools . While in the pools , astronauts wear weights so that
they dont float to the top or sink to the bottom . This is
called neutral buoyancy (BOY-uhn-see).
NASAs Neutral Buoyancy Lab
An astronaut trains in a neutral buoyancy pool .
When Archimedes (ahr-kuh-MEE-deez)
discovered buoyancy , he is said to have
cried , Eureka ! It means I have found
it . It is now a well -known phrase
when someone gures something out .
Train Around the World
There are neutral buoyancy pools all over the world . There
is one in Russia . There is also one in Germany . Chinese
astronauts practice in a pool in Beijing.
In the United States , there is a pool in Houston , Texas . It was
built in 1995 . It is part of the Neutral Buoyancy Lab . Many
things are placed in the pool to help astronauts train . Even
space stations have been put in the pool ! When an entire
station does not fit in the pool , it is split into pieces . A big
crane is used to put pieces in the pool.
