Ultimately, the Mars Project is a leap of faith.
Logically, its perfectly understandable why the Mars Project would be described as Science Fiction once we appreciate the true magnitude of the challenges involved.
Nevertheless, the desire to reach the unknown is what makes us Human, and its the reason why I believe the challenges will eventually be conquered and we will one day establish a Colony on Mars.
We probably wont establish a Colony or even land on Mars by 2024.
We are also a long way off from establishing Colonies depicted in Films and most recently TV Shows like The Expanse which appear to gloss over the enormous challenges that will have to be first overcome before we establish Society, Government and begin to have Wars in Space.
However, we have reason to hope that this will be a reality one day.
