But you're essentially right, radiation shielding is the biggest unsolved problem. Pretty much everything else can be solved with technology that we have, albeit at great expense.
There are solutions, both by artificially generated magnetic shields, and by sheer mass.

Additionally going to mars would advance the technology we need to do asteroid mining. Which would have immense value and benefit to us.

I think it's primarily a job for sophisticated autonomous robots, at least as far as the next 30-40 years. The logistics of getting humans there and keeping them alive are prohibitively daunting.

Elon musk is looking at 6 years from now.

Contact NASA immediately.

They need your insight.

Carry on.

Are you referencing plans to go to Mars?

A human being walking on mars would at least be a a moment when the world is united in awe and wonder, something that I believe is sorely needed these days. I'd say considering NASA's paltry budget, that'd be money well spent.

Plus, it could inspire a new generation to pursue STEM fields as a career option.

Not if they use nuclear powered space craft. Trip to Mars would take a couple of weeks.

Technology was developed to do this in the 1960s.

We could have been there by the 1980s. Why didn't we go?

See Whitey On the Moon.

I know, and I still think it's prohibitively daunting. I don't know what it gets us if we do get squishy air-breathers on that rock in the next twenty years. Humans are profoundly poorly adapted to the trip and the stay.

Now we're talking! - I'd much rather skip Mars' gravity wells and go hit up some asteroids.

Lol, yes, because I'll clearly take the opinion of some random nobody with an ax to grind against the "stupid government" over the experts at NASA! Right...

Tell me, do you enjoy your cell phone? Yes? Than stop grumbling about the space program. Oh, and if you enjoy having infrastructure and a military, stop complaining the "stupid government."
