Answer: Yes!
Explanation: Mars is still in the habitable zone of our sun, just like earth. The whole reason why mars is not supporting life is because of its very thin atmosphere. If we terraform mars enough, and start plant life if we get enough co2 and o2 then we can get mars to keep in the heat from the sun like earth which will melt the ice caps, Which will get us water!
Water is also probably need to be filtered due to possible being deadly if it was ingested.
The only downside is due to the soil which is toxic which we found out from the rovers. The soil will kill you, even if you grow something with it.
Fun fact: NASA does their best to make everything universal, so if we went to mars and found the rovers, then we could plug them in to new 2030 batteries and it would work because it has the same plug.
