The space rockets created by NASA, Blue Origin, or even SpaceX are not capable of bringing people to Mars, according to Chris Hadfield, a retired astronaut from the Canadian Space Agency. He thinks the current technology can fly to the Red Planet but is not safe enough for a manned mission to Mars.
“My guess is we will never go to Mars with the engines that exist on any of those three rockets unless we truly have to. I don’t think those are a practical way to send people to Mars because they’re dangerous and it takes too long,” said Chris Hadfield for Business Insider.
Hadfield, who flew in space for three times between 1995 and 2013, was the first Canadian to take a spacewalk out of the International Space Station in 2001 when he assisted to the installation of a mechanical arm outside the ISS.
A manned mission to Mars is too risky with the current technology, thinks a retired astronaut from the Canadian Space Agency, Chris Hadfield
“The technology that took us to the moon back when I was just a kid can take us to Mars, but the majority of the astronauts that we send on those missions wouldn’t make it,” affirms Hadfield.
According to him, the rockets developed by NASA, Blue Origins, and SpaceX are powered with liquid fuel, and that’s the biggest problem because this fact represents a considerable risk for the humans embarking on such a long trip in space.
“I think we need some more improvements in technology before we cross the oceans that are between Mars and us in any sort of practical way,” said Chris Hadfield after comparing a manned mission to Mars with the current technology with crossing the ocean with a canoe.
In the end, Chris Hadfield indicated some much safer technologies for propulsion to replace liquid fuel, mentioning about gravity manipulation, ion propulsion, and even nuclear power.
