Humans once had a dream to send objects into space. Then we wanted to land on the moon. Next we wanted to explore the solar system. We’ve hit milestone after milestone, and with each mission we learn the necessary skills to move on to the next. Now, our dream is even more ambitious. Now, we want to go to Mars. Simply landing humans on the red planet would be a feat in and of itself. But what if we wanted to live there?
1. Mars doesn’t exactly have a temperate climate.
The average temperature on Earth hovers around 60 degrees F. On Mars, however, the average is negative 80 degrees. Not exactly comparable. Humans are no strangers to extreme conditions, of course, so we could absolutely bring the right technology to adapt and be able to survive.
2. UV rays have no filter.
On Earth, we’re protected from UV rays by our atmosphere. Even then, of course, some get in. Mars, on the other hand, has no such protective atmosphere. Damaging UV rays make it right down to the surface, and the shorter wavelengths in particular are the most abundant. Those just happen to be the ones that are the most biologically harmful. To live on Mars, we would need to be able to protect ourselves from these rays, which we can already do with astronauts on the ISS.
3. Humans require oxygen.
We’ve adapted to our oxygen-rich atmosphere, and living anywhere else is pretty difficult. If we want to live on Mars, we’ll have to bring our own atmosphere. Most of Mars’ atmosphere is made up of carbon dioxide. Only 0.16% is oxygen. We’ve been able to solve this in spacesuits and the ISS already, so transporting that technology to another planet and improving upon it is entirely possible.
