why dont we take water in space?

The astronauts do indeed take water with them into space.  It is always kept in a sealed container to keep it from getting into everything by drifting around.  They have to take water with them...nobody can survive without water.  Even when they are outside their shuttle or space station or capsule, there is a water container inside their space suit and use a straw like fixture inside their suit to sip on when they are doing an EVA (extravehicular activtiy)

They use toilets that have suction, like a vaccuum does. The guys that go in space have to pee in a hose that has suction and that gets kind of wierd...a guy and a hose.....

why not get a pipe from the bottom of the ocean to space and pump water into space to save the sea level rising. a few boats aint gonna help

Why couldn't someone come up with an engine were you needed only water...I mean the earth is made up of like 70% water.

Of those water is the most important. If need be we could survive for about a month without eating, living only off of our fatty reserves. Shelter would reduce the amount of water we would require to survive, say in a desert, but even still we couldn´t survive for many hours completely without water.\nIf you are in a spaceship and all your oxygen disappeared you would die within minutes...

I'm not sure how astronauts filter their urine, but it certainly is possible to filter urine using a distiller.\n\nA distiller boils the liquid and catches the water vapor. Because water boils faster than its impurities, only pure water will be in the vapor.

G'day good question!!\nWell I'm all for space exploration, cos in the very long term it will be important for us to leave this place, scientists believe that places like Mars actually contain water in the soil in the form of Perma Frost, and if it could be released then perhaps we could live there one day. The giant moon of Jupiter ( Europa) is covered in a sheet of ice, what is under the ice is not known, perhaps a type of life form ( now that would create all sorts of questions don't u think?)

tap water maybe? you got sent out into space, eventually stars and such formed because of gravity, some other hydogens got turned into other elements by nuclear fusin, you probably did too but eventually fissioned back to hydrogen, at some point the sun and the earth were formed, you happened to be on earth, you probably were in a methane molecule back when the earth's atmosphere was methane, but then algae started photosynthesizing an oxygen atmosphere, at some point you broke away from the methan, met up with some oxygen and another hydrogen, and becaame water. as water, you keep getting turned into sugar by plants, but then animals eat you andturn you back into sugar.

No oxygen in space. Need to bring or make your own.\nNo gravity or very weak affects the human body in many ways, one big is it weakens ones bones(and muscles).

how are you supposed to swim on the moon? what about snowboard? i think it is pretty hard to do sports without much gravity.

Separating the Hydrogen and the Oxygen from regular water is a simple grade school physic's experiment. I have included a link to a experiment page. Now whether it is illegal in Great Briton, I do not know. Now why we don't use it, you would have to ask the major car manufactures that question. The technology is not new, there has been powerful fuel cells floating in outer space for almost 4 decades. The problem with hydrogen as a fuel, is that if it expands uncontrollably you will have one big explosion on your hands.

Firstly our wastes contains many substances like several kinds of elements for e magnesium, iron, cobalt, etc.. If we send them into space, we will lose the possibility to recycle the wastes and reuse the elements or compounds in them to manufacture other things. However if we want to get rid of them by space, this costs a whole lot of money since for sending 1 g of waste, about nearly hundred times the amount of energy needed to create that waste will be lost to propel the waste into space. So it would be illogical to do that since we would be wasting our precious energy sources, our money and also polluting our earth more by the burning of fuels to propel the rockets into space.

No.\n\nAs a result of recent ads on television, most Astronauts now\ndrink commercially bottled water.

yes they are able to do just about everything you can on Earth. Depending if you are talking about the space station or just a shuttle mission not docking to the space station. I had the opprutunity of being able to go into a mockup of the space station at space camp in Huntsville Alabamma. They have aa special shower head that turns on and off and a special shower area. Remember they are not totally weightless there is some micro-gravity. Going to the bathroom is a little tricky too. Go to Nasa website and check it out.

Water is used in about all of the chemical processes in the body. Therefore it is a waste product in most of these reactions. The very act of breathing requires the use of water. No machine is so efficient as to have absolutely no loss in any of the variables involved in it's working. Some creatures are very efficient at retaining water but at a price to other bodily functions and even then they will eventually dehydrate and die without water.\nThis is really a pretty simple concept.

ok well think about this: ours is the only planet we know of that has liquid water on the surface. others have no water or the water is frozen. If there were life on every single planet that has liquid water on the surface, we still would not yet have discovered extraterrestial life.

"bred2bbroken" covered the question well.  I add one interesting tidbit to his answer.  The sensors that tell your body that you are thirsty are in your head.  With all that blood and bodily fluids moving away from your feet and towards your head (due to the absence of gravity), you do not feel thirsty.  This causes a problem during reentry.  Suddenly, you are severely dehydrated.  This can lead to lapses in judgement, etc.  Astronauts, therefore, drink a gallon of water during their final orbit.  If reentry has to be delayed, due to adverse weather conditions or whatever, then they have to orbit again.  Guess where all that water goes?  :)  So, they make one pass around, which takes a little over an hour, and then they have to chug a gallon of water again!  :)
