There’s no way humans are going to colonize Mars. Hate to burst your bubble.
There’s no organized magneto sphere on Mars to protect people from the sun. It’s why the Martian atmosphere blew away and the oceans evaporated.
For that reason terra forming can’t be successful there, and scientifically no one wants to contaminate Mars with our germs.
We’re just going to have to fix what we’ve got. Star Trek is fiction.
