Elon Musk Revealed SpaceX Will NEVER Reach Mars..
Elon Musk is hell-bent on colonizing Mars. That's the spirit with which he founded SpaceX, his rocket company, in 2002. Musk was frustrated that NASA wasn't doing more to get people to the red planet — and concerned that a backup plan for humanity wasn't being developed, for when Earth becomes an uninhabitable wasteland.

HOW EXACTLY ARE PEOPLE GOING TO SURVIVE THE TRIP?
Musk offered few details about life inside the spaceship that would transport people to Mars. Though he promised that the trip would be "fun" with restaurants and "zero-G" games, there were no concrete descriptions of how the passengers would pass the time and, crucially, stay alive.
The increased levels of radiation that people will experience on a trip to Mars is one of NASA’s biggest concerns. Deep space is filled with tiny energized particles — either from solar flares or deep-space cosmic rays — that have the potential to harm people during the voyage. Astronauts on the International Space Station are largely shielded from this radiation thanks to Earth’s magnetic field, which deflects most of the deep-space particles. But those on missions to Mars will not have the planet’s magnetic shielding, and it’s not known what effects that might have on the human body.
Musk was remarkably casual about this danger, though. "There’s going to be some risk of radiation, but it’s not deadly," said Musk. "There will be some slightly increased risk of cancer, but I think it’s relatively minor." He went on to describe ways that Mars colonists could shield themselves — perhaps by reorienting the spaceship during a solar flare and huddling under a column of water. Still, he made it clear he wasn’t particularly concerned about this problem. "The radiation thing is often brought up, but I think it’s not too big of a deal," said Musk.
This casual approach to radiation isn’t shared by space researchers. "Radiation — he maybe downplayed it a little more than I would have," says McKay. "It’s not a show stopper, but you have to worry about solar flares." McKay also says there needs to be a "storm shelter," in which fuel or some other liquid is used to slow down and deflect incoming particles. "He discussed this very quickly. It’s a very sketchy solution, but that's basically the solution to radiation."
While there may be ways to hide from radiation, there’s something that the space travelers won’t be able to escape on their way to Mars: microgravity. People’s bodies go through dramatic changes in zero-G. They can lose bone density, their muscles atrophy, and their eyesight gets worse. What exercise regimes will the crew need to do? How will 80 days on a ship affect them? "Zero-G" games may be fun, but the entire mission will be for naught if people’s bodies deteriorate on the way to Mars.
More questions remain once the crew reaches Mars. What will they do all day, and how long are they expected to stay before they take a return trip? Musk already has some ideas about how best to run the planet — he suggests a direct democracy — but it seems unlikely that the very first people on Mars will be tasked with figuring that. Instead, they’ll be more concerned with staying alive.
Mars already has a magnetic field, but compared to Earth’s, it’s relatively weak and sporadic. The team, which includes NASA’s chief scientist James Lauer Green, proposes several methods to improve its strength and reliability, including restarting the planet’s iron core or establishing a giant loop of solid-state batteries. Needless to say, each of the suggestions would require an enormous amount of resources, all of which would have to be flown to Mars. But as the researchers explain, power for the project could come from nuclear fission reactors, which have long been considered a necessity for Mars colonization.
