I speculate that the missions to Mars and the Moon are small milestones for a bigger picture. What if they were actually training grounds for a future mission much further away? What if multi-planetary meant never returning to Earth again? We have a short lifespan of 65 to 85 years; we would see a whole generation go missing on this speculative journey.
Speculation is rife that Proxima may be the end goal, 4.25 light-years away or so. I speculate this is secretly planned to but if we pull our heads together, we could inhabit three worlds all at once.
