In Fact It's Cold As Hell
Here are some reasons not to send a lot of people to Mars anytime soon.
- Mars is about 48 million miles farther away from the Sun than Earth. You do the calculation based on the inverse square law.
- Mars has no appreciable oxygen or nitrogen; in fact, it doesn't really have much of an atmosphere at all.
- Mars has no soil in which to grow things.
- Mars has no usable water except near the poles where it's even colder than hell. It's so cold there that dry ice, frozen CO2, forms nearly year round.
- Mars has so weak a magnetic field that it is constantly bombarded by harmful radiation.
- Anyone on Mars would have to live in a very small, closed environment for thousands of generations and such a colony would necessarily suffer the inevitable loss of size, smarts, vigor and ability that plagues all small island populations here on Earth.
- The lesser gravity on Mars will be deleterious to human health.
- The smallest diameter of crushed rock on Mars would be so fine that it would get into everything, including human lungs, despite the colonists' best efforts.
- There is no life on Mars because life such as that which exists on Earth is not possible there.
- It's hugely expensive even to send a few on a one way trip there.
So by all means, let's get behind Musk's idea to colonize Mars.
How about we go get some asteroids and bring them back to high orbit around Earth first? See how life inside a rotating asteroid goes before we start shipping humans off to slow dreary death on Mars.
