There is a lot of visible evidence on Mars revealed by the various Mars landers, that water - a lot of water - flowed at one time on the planet.
The space probe found ice caps that prove that running water at one time flowed on Mars. Investigations continue to find any form of life that could have inhabited these waters.
For one, we know there are polar ice caps on mars that consist of ice. Second, there are gorges that show where water once flowed.
The moons of Mars may have been asteroids that were captured by Mars' gravity. This theory suggests that the moons, Phobos and Deimos, were originally orbiting the Sun before being pulled in by Mars' gravitational force.
There was water at one time on Mars.
THERE IS NO TIME ZONE ON MARS..... And since no one has ever set foot on mars there is no way to calculate time. When an unmanned spaceship arrives at Mars it is probably calculated to Houston (central) time.
Currently, there are none. But Mars at one time had an atmosphere (or rather, much more of an atmosphere than it does now) and Mars also had water - seemingly a lot of water. The #1 question astronomers have about Mars today is: Did Mars at one time have life?
Astronomers are now certain that Mars had water - probably a great deal of water - at one time (it still does as ice in it's polar cap), and also had an atmosphere at one time (now, just a very, very thin CO2 atmosphere). The combination of the two, with lightning from atmospheric storms mixed in, are the basic ingredients for the most elemental life forms to begin developing. Bottom line? Mars may have had life at one time.
no one has time to type that.
There is one syllable.
The opportunity that Mars represents for the Earth is the chance to conduct research on another planet that may be able to be used for human life one day. It's the hope of humans that they may one day be able to travel to Mars.
What happened to the water on mars h'm its simple really. A long time ago about 10000 million million years ago mars had water all over its surface in seas and oceans like earth. But one day a giant solar flare burst-ed out of the sun straight at mars. Mars had a ozone to protect but not as strong as earths. The solar flare made the ozone layer evaporate and evaporated all the water mars had ever had except for the polar ice caps. Then mars became a dirt land of nothing. Mars had water but probably never will again.
Not that we have found, but there are ice caps made of CO2 and water. also, we have found what seem to be dry riverbeds, suggesting that mars once had liquid water and may at one time have been not so different from earth
