We're not sure there was life there, but the professor is using the word habitability

to understand the chemical components of the ocean that dominated the northern hemisphere

of Mars. David, you have a question for the professor.

of Mars?

The southern hemisphere. I think that with my unlimited budget, there is another area.

I would love to go and explore. It's more equatorial, subtropical. It's actually in the chaotic

terrains of Mars. The chaotic terrains are extremely interesting, geologic features, because

they represent the largest windows between the groundwater systems and the surface water

systems that we know of in the entire solar system. Essentially, they are zones where the

aquifers released the water to the surface and produce immense channels that then ended

up in the northern plains. I would love to go to explore these outlets from these massive

groundwater systems on Mars. They are, as the name suggests, like, characteristics. They

are extremely complicated terrains.

The ocean, back to the northern hemisphere, the ocean that existed at the day of the event,

that ocean was fed by aquifers. I find it's incorrectly. The aquifers were feeding liquid
