Ludicrous.

I would never trust a study by a single scientist, or small group of scientists, until more research backed the findings. I would also not react to such a study until thoroughly reading and thinking it through....

There's not much here to think through. There's an an assertion than a man could travel to Mars.

I think a lot of people would like to believe it but I've seen no evidence at all.

There are a lot of AI generated pictures that would look good in a science fiction movie.

Props for that.

There is an assertion that we can NOT travel to Mars because one study sees potential kidney issues. One study. Did you read that study? I didn't even see a link to it. "One scientist warns, blah blah."

Crap journalism for the intellectually lazy reader.

I agree. Crap journalism for the intellectually lazy reader

But it literally says man could make it to Mars just not home.

I think the assertion (science??) is ludicrous.

Why is travel to Mars ludicrous? NASA has been laying the groundwork for years -- preparing for long-duration isolation, medical issues, radiation issues, propulsion, landing, and so on.

We understand the physics of getting there quite well.

I don't believe it's possible but regardless of what I believe, why would you want to do it?

And, wouldn't you agree-- even if we, "have the science," the science is theoretical?

You can go first.
