You don’t want me to answer this question. You are looking for a great, positive answer that will make the future look bright not only for colonies on these places, but an economic base for those colonies.

Meanwhile, I’m going to say I don’t think there’s much justification even for people walking on Mars when our robots can do it more safely and less expensively and achieve the same or better results…. what to speak of “colonies.” I think it’s almost laughable and mostly just science fiction dreaming.

People may or may not one day walk on Mars at great risk, and some will probably die in the attempt. There is little reason to go there from a scientific point of view other than to say we did, just like we walked on the moon and then went away.

In the meantime, a safer, cheaper way is send our machines to go.

You see, what this is all about is finding life. What scientists want to do is prove that life can evolve elsewhere than Earth – a so far unproven theory. We want there to be life elsewhere because we want to prove that life was not “created” on Earth alone, but life naturally develops from matter when conditions are ideal.

We don’t need “colonies” or economic bases in space to prove that. We just need to find some germs under some rocks or on some moon around some planet in our solar system. For that we just need space vehicles and robots like the Mars Rovers.

Whether we find life or not is anyone’s guess, but it is still science fiction thinking we will colonize anything off planet.
