You can go to the surface when something goes wrong with the submarine. You can make oxygen from water. In general, you have plenty of water. You can be rescued. On Mars, when even the slightest thing goes wrong, you are done.

You're under massive pressure and flying near blind in a domain where a impact could easily mean everybody dies. On Mars water will not be an issue. Settlements will likely be near areas with abundant water ice, but even in the extreme scenario it turns out the Martian soil is oddly 'moist.' It turns out that the Martian soil ranges from 2%-5% water by weight! This is something "The Martian" got accidentally wrong, since that discovery was made after the book was written.
