It doesn't matter how many people you send to Mars, you cannot live there. See the videos by Common Sense Skeptic.
Mars (and Venus) do not have a magnetosphere to protect you from radiation. The gravity is the wrong amount, so your bones will dissolve. Mars itself is poisonous.
Write down every aspect of living someplace that you need: gravity, water, temperature, lack of radiation, etc. and in every way Antarctica is as nice or better than Mars. I don't see people clamoring to live in Antarctica.
One nice feature of Antarctica: if you want to go home, you can do so in a normal ship: no space ship required.
