For astronauts, learn to use the toilet in a spacecraft may be more difficult than when he had to complete a physics equation to calculate the trajectory of a rocket being launched. To that end, NASA has a specially designed training room at Johnson Space Center in Houston where astronauts can hone "technique" to use the toilet before leaving on their trip into orbit in real space.

In these places there are two toilet training room is the space rangkasa positional training room (for practice) and functional training (for rinsing). Positional training is not practical to use the toilet as toilets in general, but rather a true replica of the toilet on the space shuttle. The width of openings on the toilet seat only about 10 cm (standard toilet on earth have openings measuring 30 to 45 cm).

And not only that, there is a small camera inside, just below the edge of the aperture, and the camera image is displayed in the monitor located in front of the toilet seat. With all of this, astronauts can ensure that their bodies are in the right position so that their droppings will fall through a small hole located on the toilet.

When astronauts have mastered this technique properly, they can move to functional training. The training room is in the form of a regular toilet equipped with a ventilation air flow similar to that used on the space shuttle. Here, the astronauts will practice how to eliminate both urine and the remaining dirt on them.

In the spaceship, the urine is handled differently with how to handle solids. There is a long hose attached to the suction side of the toilet seat, and the astronauts will urinate through this hose. These channels would have different shapes for men and women.

Women need to put the top of the drain urine directly against their bodies, so that the urine drains women should have to get ventilation so that air can flow when the vacuum is turned on. And women can choose among three channels with the top shaped differently, there are two lines to the top and an oval-shaped with the top circle.

While the channel for men is very simple. Where the channel has only one circular shape with the top, and has no ventilation. And finally, for the former toilet tissue, a separate suction hose on the side of the toilet can be installed with the "cup" bigger and lined with a plastic bag.

Strap on the back foot where it can help to hold astronauts remain in place, other than that there are two limiting thigh on the side of the toilet which can swing from the top of the foot to help someone stay on top of the toilet. But not everyone is using it. Prior to launching missions into space, astronauts gathered in this room and compare their techniques to remain in position when they are in a state without gravity.


So where then all the waste? Do not worry, they will not come hurtling into the Earth's atmosphere and landed on the roof of your house. Solids will be dried to remove all water vapor, then compressed and stored in a storage container which would then be disposed of after the spacecraft had landed. While urine will be sent into space for granted.

On the International Space Station, urine is recycled through a special water treatment and back into drinking water. While the solids will be put into a plastic bag. Every time someone goes to the bathroom, plastic bags will be sealed and compressed like a trash compactor. The bags are then collected and placed in a special vehicle that was launched into space.

Shitting affairs will be even more challenging when the astronauts are on a mission "space-walk" outside their spacecraft. The astronauts would normally use adult diapers "super-absorbent". Diapers can save up to one liter of liquid. In addition, the astronauts also use adult diapers during take-off and landing because it certainly is not possible for them to use the toilet at the time.
