your signature is a call for the complete genocide of the Jews, right?

Here's an Israeli using the term as it is usually understood so-as to remove the straw man you've neatly planted:

It's a curious attempt to paint a slogan calling for freedom for Palestine as genocidal when they are actually victims of genocide committed by Israeli Attack Force.

It's really hard to convince the world you're a potential victim of the thing you're actually doing to others.

While it is an enormous problem, possibly the most significant, we know how to shield against radiation, but it's going to take mass in the form of hydrogen-rich molecules like water or polyethylene (as examples). To solve that problem we are either going to have to make launches a lot cheaper, or figure out how to do it all in orbit.

It's at the edge of our technological capacity to produce such a spacecraft now, so the barrier is economic. That's a massive barrier, but in theory we definitely could, if we put a significant percentage of GDP of the wealthiest nations towards the project, produce a spacecraft that keep astronauts alive and relatively protected from ionizing radiation both on the journey and while on Mars.

As to your general assholery, I guess everyone has to have an outlet, though why Slashdot is a bit mysterious.

The Moon is target practice. We need to get away from innovative bespoke engineering, into industrial mass production with continuous improvement. To do that we need to fly often. Mars just doesn't have the launch window availability. The biggest part of the challenge is that we were born in the bottom of a deep well. To toss enough stuff out of the well for a long journey is critical. Boosters that reliably fly on time often and cheaply enough to get ships and fuel out of the well. Ships that carry fuel into orbit and return over and over since the vast majority of the material we need to send out of the well isn't payloads or ships, it's fuel. Kilotons of fuel. Once the factories and processes are set up for that going far beyond the Moon is fairly easy. But with a narrow opportunity every two years that's not going to happen in a human lifespan. It's not enough refinement cycles per year.

I see this accelerating the Mars objective, not deferring it.
