I don’t have any questions about a mission to Mars, it is a stupid and pointless trip that I don’t want to ask any questions about.
The Moon, I dunno, it’s at least in Earth’s gravity well so it isn’t like we’re going totally the wrong direction when we go there, right?
At best it could be a gas station on the trip to somewhere interesting like the Asteroid belt, though.
Whether a moon base is needed or even beneficial is a question I have not heard a convincing answer in favor. And even if moon base is indeed needed and/or beneficial to future space exploration / resource extraction why robots cannot more efficiently build (or assemble) such a moon base is another question I need an answer to.
We are sending humans to (or around) the moon now, but it may just turn out to be a wasted effort, done solely for the opulence (or more cynically bragging rights / nationalist propaganda).
