Who's Going to Mars?

Applications are now being accepted.

 

If they get there, Mars astronauts will face a lonely life of danger, subsisting for extended periods on dried and canned food. They will get some of their water by recycling their urine.

 

They will have to take care of sickness and injuries themselves.

 

"There will be emergencies and deaths," Lansdorp said. "We need to make sure that crew members can continue without those people."

 

Mars astronauts will have to be mentally fit to deal with the unusual stresses, he said.

 

"Their psychological skills will be the main selection criteria we will use," he said.

 

Once selected, a group of 40 astronauts will undergo seven years of training.

Would only apply if they explained how they'll deal with the radiation problem. Have not done so.

Mars has radiation? Or do you mean the lack of a magnetosphere?

Once you get outside of the Earth's magnetic field, you enter a radiation environment impacted by both the sun and galactic cosmic rays. The Earth's atmosphere and magnetosphere protect people while they're within it, but on a 6 month or year long voyage to Mars, you're getting a lethal level of exposure. You can line a spacecraft with something like several inches of lead to cut down on the radiation exposure, but that's an enormous amount of weight to lift off. The radiation dosage you get would be near lethal on the voyage there.

Need to ask the guys in the UFO's how they manage. Maybe they have some kind of immunity.

If you could actually have an industrial setup in space, you're set, because there are plenty of resources on asteroids, just no processing facilities. The problem is having a rocket with enough lift capacity to lift large masses out of a planet's atmosphere. If you can come up with power from some sort of fusion source, great, that does it also, but chemical propulsion is very inefficient in energy per mass. It's a tough problem unless you stop caring about costs, and the only time that ever happened was when we beat the Russians to the Moon.

Otherwise, you would sign up, eh?

Just constantly apply SPF 750

Hopefully everyone that's ever been on "reality tv" is sent to Mars, and they never come back.
