Is There Water on Mars?
We Asked a NASA Scientist.
The short answer is yes.
Now, we have to think about, how do we actually define water?
It's not quite like on Earth, but it's definitely there.
Water is a molecule that has one oxygen atom and two hydrogen atoms. The ice on Mars is a little bit different than on Earth.
On Earth, usually the ice is just, you know, water ice.
But on Mars, it's actually water ice and CO2 ice mixed with each other.
On Mars, it's just so cold that it gets frozen, so you actually have those mixed together both at the poles and underneath the surface as well.
We even have water in the atmosphere as a water vapor.
