Mars researchers suspend reality when working in Utah desert
The Mars Society chose the American Southwest for its training facility because the soil and lack of vegetation resemble the landscape of the red planet, but that's where the similarities end.
Most of the simulations in Utah require participants to imagine the conditions of Mars, suspending the reality around them. A look at some of the main differences between Mars and the Earth:
DANGEROUS RADIATION
Astronauts venturing into deep space on their way to Mars would face radiation from high-energy galactic cosmic rays spewed by distant supernova explosions and sporadic bursts of charged particles hurled by the sun. Earth's magnetic field helps to deflect much of that radiation. Astronauts would be bombarded with as much radiation as getting a full-body CT scan about once a week for a year, according to researchers who reviewed data from a radiation sensor aboard a rover during the journey to Mars. In some cases, that dose would exceed NASA's standards and be enough to raise an astronaut's cancer risk by 3 percent.
NO RUNNING WATER
There is no liquid water on the current surface of Mars, though scientists believe that the planet had running water long ago. That belief comes from the fact that Mars has river beds and canyons that were probably formed by water. Mars does have frozen water on its polar cap, which is a mixture of carbon dioxide ice and water ice.
NO OXYGEN
On earth, 21 percent of the atmosphere is oxygen and less than 1 percent carbon dioxide. But on Mars, 96 percent of the atmosphere is carbon dioxide and less than 1 percent is oxygen. That means astronauts must wear spacesuits at all times.
FREEZING TEMPERATURE
The Earth has some cold places, but they pale in comparison to freezing Mars. The average temperature on Mars is minus 81 degrees, with lows reaching minus 284. Earth's average temperature is 57 degrees, with the coldest temperature ever on record being minus 126.
GRAVITY
Mars has 63 percent less gravity. A person who weighs 100 pounds on earth would weigh only 38 pounds on Mars.

This sounds like science fiction, but as a big fan of sci-fi, I know that science fiction leads to science fact! Without the creative influence of sci-fi, we might never have landed on the moon! (-:Meet The 'Space Train' Concept That Can Get to Mars in 2 Days
"Charles Bombardier, a Montreal-based innovator, has unveiled a concept for a hypothetical space train called Solar Express that can shuttle passengers and payloads between planets faster than any existing systems."
"So, how would it work? Well, according to the team, Solar Express would consist of a series of aligned cylinders roughly 50 metres (164 feet) in length. Six of these cylinders - which you can think of as train cars - would link together in a straight line and hurtle through space."

Maybe, maybe not.Only dreaming......?
My hope that those who eventually go, will know better.
However if Man does not learn to control his greed, maybe not.

I believe that is the motivation behind our research on other planets - We are almost done screwing this one up beyond repair. We've pillaged and plundered and now must seriously consider alternatives. If they confirm viable water on Mars, it may be the next sanctuary for many people on Earth. (Okay, I exaggerate, but!) By the way, one of my favorite movies is "Total Recall." Virtual is good enough for me!Only dreaming......?

China will launch a rocket to Mars hoping to land a rover there very soon.
US will be going to the sun but it will be at night....

@RadishRose - The advantage we have in rehabilitating Earth, is that we are already here. We have Oxygen, water and no travel expenses. What does Mars offer that is more attractive than that? I think I'd settle, for President of Earth.

I believe you'd get this place cleaned up! You have my vote.

Very timely! The benefits of joint efforts between commercial entities and government(s) were proven today. I was most intrigued by his idea of landing on one of the moons of Mars. Also liked the idea of permanent vehicles to circle Earth and Mars (Cycler) so that coming and going is continuous... next best thing to an elevator!

Put that on my YT Watch Later queue! Thanks.
