I do not believe humans will ever colonize another planet. We are tethered to the Earth by crucial bodily functions and are essentially slaves to water which is incredibly heavy. Did we land on the Moon? At one time I was convinced it was a true event. But now, not so much. Landing people on the Moon would be huge achievement in human history and it would not be ended for over half a century if it was an actual accomplishment. My concern is not based on lack of stars or flapping flags. I think the purported peopled Moon landings were politically staged events not a scientific breakthrough. Today with all of the new superior technolgy in our possession we have not been back. I think it would be too hard to fake it today and that is why it is not happening.
I know there is a lot being bandied about with Mars landings and such. But making that a reality is out of reach in my opinion. We are already on a space ship and that is the Earth. But we cannot get off.
We need what the Earth has and cannot survive without it. Now, we could explore with non human piloted craft operated and controlled by artificial intelligence-AI. But I believe humans are never going into the cosmos as living, breathing, lifeforms.
Sorry to burst your bubble. Do you think humans with their horrific history could engineer a way to escape and infect deep space with their spiritual and physical failures? It's not happening. The experiment is ongoing but it is at a point now where a global collapse is not out of the question.
We will be lucky if we survive much longer on our own planet.
Medical, financial and ethical hurdles stand in the way of the dream to settle in space
