Mars colonisation is a hype topic. What is the biggest threat for those wishing to take a part in a journey to Mars?
low temperatures
lack of oxygen
poor gravity
cosmic rays
The only efficient protection against high energetic cosmic radiation, one we are granted with, is Earth's magnetic field. Both during a long flight to Mars and through the stay on the planet, that did not form electromagnetic field, astronauts would be exposed to ionization.
