I mean, I think it's fairly obvious that we will never be able to colonize Mars perfectly. It would require constantly sending massive amount of supplies from Earth to Mars. The atmosphere is too thin, and the planet itself is too small to maintain a real atmosphere. Even if we terraformed it using science fiction technology, most of the atmosphere would escape into space so it would require constantly producing this atmosphere, requiring a lot of off-planet resources, which is fundamentally impossible. In addition, the lack of strong magnetic fields and Van Allen belts means that cosmic rays would kill everything eventually.
