Former International Space Station commander Chris Hadfield shocked the world, saying that the same technology that would have brought the man to the moon could have sent people to Mars.
He said, "We could send people to Mars decades ago.
"The technology that brought us to the moon and back when I was a kid – this technology can take us to Mars."
But no astronaut would have survived the journey, he said.
In fact, he believes that the 140 million miles separating the Red Planet from Earth would be fatal to anyone brave enough to try the journey, despite the fact that space rockets would probably be able to get there bring.
Mr. Hadfield said, "The majority of the astronauts we send on these missions would not make it, they would die."
Mars is 660 times farther than the Moon, meaning that a return journey would take anywhere from 500 days to three years.
The dangers that astronauts face on their travels to the moon, hunger, the risk of explosion, and exposure to radiation would be greatly increased by the length of this incredible journey.
And the fact that even new space programs such as SpaceX still rely on chemical propellants to leave the earth, increases the dangers.
The greater the distance to the destination, the more space is needed for fuel reserves, thus losing space for food.
There are a number of systems that can mitigate the effects of radiation and the risk of starvation, such as a different kind of fuel, light shielding, hibernation capsules, and bioregenerative life support systems, but none of the players involved in the new space race have found similar solutions, Hadfield said ,
During Hadfield's career, the former astronaut flew in two NASA spacecraft, a Russian Soyuz spacecraft, and aboard the International Space Station.
But despite his experience with groundbreaking technology, he can still be admired for his progress.
He said, "Space travel was impossible when I was born.
"And I'm still alive, it was not very long ago.
"Someone has to invent something that we have not thought of yet.
"It sounds weird, but we figured out how to use electricity and what electrons, and that seemed crazy, and it revolutionized life and travel.
"So who knows?"
NASA believes the first trip to the Red Planet could only be a decade away.
Following US President Donald Trump's approval of the Space Policy Guideline 1 in December 2017, the US Space Agency announced it would send a man to Mars in the 2030s.
The Space Policy Guideline 1 meant a leap in the settlement of space, as it required extended human exploration of the solar system.
Following the signing, NASA designated the decision as "a change in national space policy" and provided Washington with a US-led integrated program "with private sector partners for a return of the human to the moon, followed by missions to Mars and beyond." ,
