It doesn't matter the weather, it matters on the experiments that we will do. Mars is a very interesting place and it would be cool if we had people living on mars in a new environment. All we are really doing is making a new living space for people to live and to make more space.
It is -55 degrees Celsius (-67 degrees Fahrenheit) it is also a frozen desert there is not enough precipitation to get enough water. We probably don't even have enough money to be able to colonize on Mars. Also we have never successfully traveled to Mars so why are we trying to colonize there.
