The robots sent to Mars have found Water Ice in large quantities on the surface of Mars.
Mars has evidence of erosion by water, including river valleys, channels, and minerals formed in the presence of water. Mars once had liquid water flowing on its surface, shaping the landscape over time.
NASA photographs of Mars are the best evidence that water has been flowing on Mars recently. During warmer periods in Mars' atmosphere, the photographs show streaks that look like streams. Scientists agree that this is evidence of water on Mars.
it has evidence of water
No. While there is evidence of liquid water beneath the surface there are no oceans on Mars.
yes. there is water underground and scientist believe mars once had streams, lakes, and an ocean
Yes, Mars has water in the form of ice. Scientists have also discovered evidence of liquid water on the surface in the past.
There is no evidence of aliens on Mars. They have just recently discoved that there may be signs of water.
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.
Evidence on Mars such as dried-up riverbeds, mineral deposits that form in the presence of water, and the presence of ice caps suggest that liquid water may have existed on the planet in the past. Additionally, recent discoveries of hydrated minerals on Mars provide further evidence that water played a significant role in the planet's history.
Mars
We all know humans need water to survive. If we find water on Mars, astronauts don't have to carry all those tons of water to the planet, and they can stay on Mars longer to do research.
Because almost everywhere water is found on earth, even in very extreme conditions, life is also found.
