How To Die On Mars
An anonymous reader writes: Many space-related projects are currently focusing on Mars. SpaceX wants to build a colony there, NASA is looking into base design, and Mars One is supposedly picking astronauts for a mission. Because of this, we've been reading a lot about how we could live on Mars. An article at Popular Science reminds us of all the easy ways to die there. "Barring any complications with the spacecraft's hardware or any unintended run-ins with space debris, there's still a big killer lurking out in space that can't be easily avoided: radiation. ... [And] with so little atmosphere surrounding Mars, gently landing a large amount of weight on the planet will be tough. Heavy objects will pick up too much speed during the descent, making for one deep impact. ... Mars One's plan is to grow crops indoors under artificial lighting. According to the project's website, 80 square meters of space will be dedicated to plant growth within the habitat; the vegetation will be sustained using suspected water in Mars' soil, as well as carbon dioxide produced by the initial four-member crew. However, analysis conducted by MIT researchers last year (PDF) shows that those numbers just don't add up."
Except underground, which is the obvious solution but people are too fixated on making housing above the ground.
Even on Earth, living underground would shield us from the extreme cold and extreme heat. That would be better for us and would require a lot less energy to warm us in the winter and cool us in the summer.

Option one: You live a long but uneventful life in an unremarkable job. You are loved by friends and family,but after your death your memory soon begins to fade. You accomplish little of any lasting effect upon the world.
Option two: You life a life of adventure and challenge, and die young in one of the many tragic accidents that your inhospitable environment causes on a regular basis. You pioneer a new way of life, and there's a good chance of your name going down in history books. You contribute to something that may change the course of history.
Either way, you end up dead - but for a lot of people, option two looks more appealing.

I seem to recall hearing some recent developments in science, some wacko claim by some Italian guy that the acceleration due to gravity was actually independent of the mass of the object. That would indicate that both heavy and light objects would accelerate the same way under the influence of gravity on Mars. What a silly notion, I'm sure the Pope will cure him of his heresy.
