How so? A submarine on Mars would work just as well as a submarine on Earth. Both lack breathable atmosphere and can support crews for months on end with zero exposure to the outside. In what way is sitting on the surface of mars different from sitting on the floor of the ocean?
- rqtwteye 2y agoYou 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.
