I think the thread title accurately reflects what I heard on NPR today. It was an author interview, I was in and out of the car, but I heard the author say he was deeply impressed by Musk's plans. You can listen at the link.

I had a quick listen to this Stephen Petranek guy, but I'm not sure if he is any more credible than the fantasist Bas Lansdorp of Mars One.
Stephen Petranek says the technology to get to Mars has been around for 50 years........but crucially he doesn't specify a manned mission.

For a manned mission we simply do not have the current technology to land a manned craft safely, nor have we currently the technology to shield against cosmic rays.

Elon Musk can say what he likes but that makes it far from a reality.............particularly when his own space ship "Dragon" didn't make it beyond Earth's atmosphere before being destroyed just last month.
Musk concedes that rocket technology is hard..........and that is just to get to the International Space Station in low Earth orbit!
It's great that Musk has a vision to populate Mars.............but the reality seems somewhat different.

I actually googled Cosmic rays and started to wonder, why do we still rely on faucil fuels when there is just so much energy around us.

I agree with the cosmic rays argument - but why shouldn't a suitably trained pilot be able to land a manned tail-sitter rocket on Mars?

Mars would make a great penal colony. It sure as hell won't be a pleasure!

What this reminds me of is the optimism and personality type of an early Heinlein novel. Science Fiction when it started did not assume it would be nothing but a government program, but individual ones as well. It assumed the first pioneers would go expecting not to ever return, but they would be the kind who relished the dream and the adventure.

I think someone will go to mars and end up establishing a colony there. It may not be soon, but as more is learned the chance of survival will increase. We need dreamers and engineers to make it happen.

This colonize Mars craze is insane. Mars has 1/3rd the gravity of earth and quadruple the radiation. After three years on Mars your cancer would have cancer.

It is impossible for a human woman to bring a healthy child to term in this environment.

Plus... guess what... no water, no food, no organic material. -100 degrees at night and +200 degrees during the day.

Insane.

Actually, Mars doesn't get anywhere near 200 degrees F. at any time. Mars is a cold planet. Due to its thin atmosphere the planet can't retain heat. During the Summer, at mid day, at the equator, it may get up to around 70 degrees F.

What is the Temperature of Mars?

And there is water on Mars, though how much, and how much is liquid water is not known.
