is there water on mars?

Let's plan a road trip and find out -- are you in?

The water in this planet can support all of it inhabitant but places like desert have difficulties in getting enough water. We need water because we use water as a medium to cool down.

i think u asked this Q coz u c some movies say that there r aliens on mars.....no scientific proof  says that there r aliens on mars ...NOT on this galaxy ....Maybe there r other creatures in space...WHO knows!....i hav read many books about aliens on mars but they r stories..just stories

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.

No, but some theories must confirm it now. The best theory is that there are water on Mars long ago. That may prov that there is life on mars. The problem is, it's not proven yet, and other theories are here.\n\nBut remember, every life in a planet starts with water, so maybe, bacteria evolved into sea animals because of water, then to reptiles, to animals, monkeys, and so on.

years ago i read a article about NASA and long space trips.  the one problem was water.  the solution was bring it with you.  the if by the use of sound waves putting H20 in space in the odd type of ship and it was being moved with sound waves.  Kinda cool idea.  but back to your question I would imagine that it is possible to have a sphere of water but it would have to be heavy water low oxygen in the water hence no plants and no life (as we know it).  i see it as having to be man made with some kinda core to bounce heat back into the water to keep it from freezing.

First, there have been proof of river beds and the like being found when space probes landed there.  Second, there are ice caps seen at the poles, and that's a sign of water as well.  But as for standing water, water that EXISTS right now, there is no sign or proof.  So it may have been there in the past, but not right now...

According to current accepted beliefs, there is no people in Mars, although there has been fossils of single celled organism.\n\nWe should stick to this, until we found any further information about living things in Mars.

NASA's global hydrology and climate center may be what your looking for.\n\nhttp://www.ghcc.msfc.nasa.gov/GOES/

No, not really. However scientists have found traces of water present in some core samples. They generally believe that Mars did have oceans and lakes and an atmosphere like Earth. A very long time ago. I'm sure you could get all the information you need at the NASA web site.

>>>What are all the planets and moons besides earth and Europa that have liquid H20 water on them? \n\n\nAs you point out the three gas giants are all believed to have layers of liquid water. Added t that there are trace droplets of liquid water in the atmosphere of Venus but they don’t last long individually.\n\n>>>>>My astronomy book says Uranus has water on it underneath a massive layer of liquid hydrogen but this can't be right. It says the temperature there is -360 degrees F and water freezes at 32.\n\nThe ‘surface’ temperature is –360oF. Just as the surface temperature of Earth is 80oF. But as you get deeper into the Earth the temperature increases until it is hot enough to melt rock and iron. And in exactly the same way as you get deeper into the centre of a gas giant the temperature increases until you can melt ice. \n\n>>>>>>. Could life exist with the h20 but virtually no solar radiation? Primitive simple life forms I mean.\n\nIf conditions are relatively stable then where primitive simple lifeforms exist, advanced complex lifeforms can exist even more easily.\n\nCould life exist under such conditions? Sure. It wouldn’t be life as we are normally used to it, but it is perfectly plausible. Life on the surface of the Earth today is almost entirely dependent on solar energy only because that is the most efficiently harvested energy source. It allows those organism that use it to outcompete any rivals using alternative energy sources.  But life didn’t start out relying on solar energy, and the vast majority of all life on Earth today doesn’t rely on solar energy.\n\nLife started out harvesting energy directly from the rocks. Those first lifeforms used iron and sulfur for energy, not sunlight. And even today the weight of the bacteria deep underground that  rely exclusively on energy form rocks is far greater than the weight of those organisms that cling to the surface and rely on sunlight.\n\n\nThere is no reason why life on other planets couldn’t survive perfectly well using similar systems of energy harvesting. And the only reason mineral consuming lifeforms never got very complex on earth is because the Earth is volcanically active, which make sit hard for big complex creatures to survive.  On a gas giant at the interface between the atmosphere and the oceans that wouldn’t be a problem, and life could evolve to become as complex as it liked.

1.  On Mars, yes.  It's only microscopic life though.  Sedna, I have no clue.\n\n2.  Go here.  It'll provide a great answer to your question.  http://www.pbs.org/wgbh/nova/sciencenow/3210/01.html

Of course there is.  You would have to be crazy to think we're the only ones in the universe and the parallel universes, and so on.  They found rust on Mars, which means there was water - therefore leading to the conclusion of life on Mars.  If there was life on Mars, you better believe there's some kind of lifeform billions and trillions of light years away.  No life was discovered yet because we haven't built rockets that are capable of taking us to the destinations of where we haven't discovered yet.

water is water everywhere in the chemical sense of good ol' H2O (imagine it was a small 2).  Water exists in the form of ice in various places:  in comets, ice caps of Mars, and some of the rings around Saturn are made of ice particles.  Jupiter's moon Europa is covered in water ice sheets like the arctic ocean.\nTechnically the only "pure" water is distilled water... all other naturally occurring water on earth has some impurities, even rain.

There may actually be some water on the moon, but it would have to be in the form of ice crystals to have survived.\n\nThe Moon has very little gravity, and it is insufficient to prevent water in liquid or vapour form from drifting off into space.\n\nCurrent theory has it that the Earth actually received much of its water from meteorite impact and, as such, the Moon should have received a similar amount of water. So, on this basis, the assumption that it is due to a lack of constituent parts (hydrogen and oxygen) is incorrect.\n\nThe NASA weblink below gives more details.

MARS... quite possible

Mars being very hot now is not a suitable condition for humans and plants, as we know it, to live.\nBut now that Water in the form of Ice has been confirmed, it is a possibility for us to live there, provided that the ice has to be vapourised to create water clouds, and subseqently the clouds should give out rain, and when this chain starts, the creation of oxygen could be obtained by growing plants which emit oxygen. \nWHEW. That my friend is a hectic task ahead (and probably not feasible also). So may be, just may be, that some where about at 200 years down it could be a dream come true.\n\nBesides, we would only be intruding the rules of the Nature by doing so.
