If there was ever water on Mars, then there might have been life that evolved on Mars, and possibly even life that was carried to the Earth as a result of some violent meteoric impact which sent debris into outer space from Mars. In any event, scientists are engaged in an effort to better understand the universe in which we live, and this is a significant detail that they would like to know. As our understanding increases we often do not know exactly what the implications or consequences will be, of any new discovery, but we keep discovering things just to see where they may lead us.
They found water there.
No scientist has ever been to Mars.
Astronauts went to mars and had a interesting theory and had some proof and took tests
No animal could live on mars as far as scientist know scientist have sent out the opportunity and spirit rovers that found ice which proves that there was once water on mars
No scientists from Earth have ever been to Mars.
No person has ever been to Mars. No spacecraft has ever surveyed Mars and returned to earth. No spacecraft has ever landed on Mars and lifted off again. No liquid water has ever been observed on Mars, and no samples have ever been removed from its surface. In conclusion, we frankly don't know what the question is talking about.
Didn't you just ask this question? No one has ever been to Mars, how would we know?
in the polar ice cap, located north of mars
because scientists researched it and found out there is seasons on mars
its all red
Mars.
There is water in the form of ice under the "top-soil" of mars and when ever it gets uncovered it evaporates fairly quickly. so there is also water vapor, what happens to that vapor I don't know. Currently we don't know if there is liquid water on mars, we haven't found any yet, and just the fact that there is water-ice on mars is really miraculous
