I'm seeing silly clickbait surface around the latest Martian speculation, so here's Phil Plait on the possibility of a deep underground water store on Mars.

The coolest part is the explanation of how this educated guess was made. Also:

"This isn’t just abstract knowledge, either. We don’t really understand Earth’s magnetic field, which is absurdly complicated. The more data we have on planetary magnetism the better we can figure out our own."
