.. making it a literal suicide mission.

It is a suicide mission right from the start. We do not have the technology to shield a spaceship from cosmic background radiation.

By the time a spaceship reaches Mars, any moron inside it would have received about a 40% lethal dose of radiation. This means that once you are on Mars, you are really, really sick. Missing a magnetic field, cosmic radioation continues to slowly kill you (unless you dig into the ground really, really deep). If you plan a one-day mission to pick up some Mars dirt, by the time you return to Earth, you are dead.

Instead of this Mars nonsense, people with the money should take care of Earth, not Mars. Where are all those fancy robots companies are developing? That is the road to take, not kill morons on purpose.

They will get a lot of radiation, no question about that. And they will get very sick from it.

Those 40% are however stretched over a long timeframe, so actual damage is somewhat lower. Nonetheless, yes, this is part of the suicide mission design, and they will die on mars a couple months after arrival due to it.

While I'm all in favor of space exploration and eventually colonization, I agree that it's way too soon to do so, the tech is simply not there for it, and won't be for quite some time. Until we can create a sufficiently sized and powerful magnetic field around the spaceship (at least around the habitable parts of the ship) to shield from the space and solar radiation, Human-rated missions shouldn't go any further than the moon.
