Terra (Firma) is the planet Earth.
What the the hell does this have to do with Mars? Earth was populated over a long time via evolution, not starting from scratch with a dead planet by humans from another planet.
Start looking at NASAs reports on the toxicity of Mars’s soil and it’s 1% atmospheric of earth and you will see why colonialism of Mars is a very bad idea. This doesn’t include the massive radiation astronauts will receive in their 86 weeks of space travel plus the radiation on Mars for their duration on the planet.
It’s a 1 way trip baby.
