It sounds fanciful but Musk, in typical Musk fashion, gave a hugely optimistic timeline for the first launch – 10 years from now, around 2026 or even as early as 2024. Yikes.
Optimistic? Ludicrous is the word I would use. It simply couldn't happen by 2026. Mars is too far away. If anyone did get to Mars it would only be one person -- probably a women as she's lighter etc. Then they wouldn't be able to get back to Earth again. The prediction is just silly.
Also I have no idea why anyone would want to go there. It's a barren, airless, uninhabitable rock. There's nothing of any interest to see, certainly nothing to do there. It'll be the same for virtually every single planet in the Universe.
However, I do think we'll get there eventually. I estimate that a human -- most probably a woman -- will first step on the surface of Mars on Saturday the 20th July 2069.
