They succeeded better in convincing me that there are no habitable choices in the solar system than Titan being the obvious choice. Mars will probably be our next destination as the best-fit of several ill-fitting choices. We need a propulsion revolution to reach Titan.

We ask why they would go to that trouble. We can live underground on Earth. What’s the advantage to doing so on Mars?
It's never seriously discussed, are they expect to live full time underground on Mars? Why then? We can live same way on Earth.. Does Elon Musk knows something we don't?

Terraform the moon. I want to look up to the skies and see a green moon every night. It is unfortunate we haven't spent a dime settling a moon base and studying the possibilities of creating a livable atmosphere on the moon being just a couple days away.

Because it's a different planet.

I strongly believe we'll never permanently settle anything beyond earth, for reasons pointed out by this article among others.

That said, please prove me wrong, I would be so very happy to be wrong.

> It might be possible to live suspended by balloons high in Venus’s atmosphere, but we can’t see how such a habitation would ever be self-sustaining.

I think they're a bit too dismissive here. I'm a great fan of the colonisation of Venus, and don't really see a problem with self-sustaining stations in a place with pressures and temperatures naturally fit for humans, with lots of sunlight for energy and lots of CO2.

After all, as long as there is plenty of energy, carbon, and oxygen, we should be able to synthesise mostly whatever we want.

This article has no good reasons for Titan, it doesn't discuss water, it doesn't discuss energy or how to grow food. It says that because you can fly there and there are dunes and a liquid surface in some places its like Earth, but that doesn't help us to survive at all.

To survive we need water, food and energy. How are we going to get that from Titan as opposed to Mars?

The moon doesn't have enough mass (gravity) to keep an atmosphere suitable for us there.
