G'day all, I'm new here. I just have a quick question for you; how can I make Mars habitable?
I've been building a star system and I'm finding it difficult to introduce liquid water and raise the planet's temperature without it super heating and just burning away into nothing. I'm using Sirius as the star and Mars is within the habitable zone but when I increase the atmosphere the temperature spikes and it all goes to pot. Is there any way to make a sustainable, habitable atmosphere for Mars?
