Your kids might live on Mars. Here's how they'll survive | Stephen Petranek

  • Published on: 05 May 2016
  • It sounds like science fiction, but journalist Stephen Petranek considers it fact: within 20 years, humans will live on Mars. In this provocative talk, Petranek makes the case that humans will become a spacefaring species and describes in fascinating detail how we'll make Mars our next home. "Humans will survive no matter what happens on Earth," Petranek says. "We will never be the last of our kind."

    Terraforming such a planet would be the expense of money that will not be sustainable. Not to mention the fact of what will anyone do if any human over there becomes sick or worst.

    im confused why he said its possible by 2027 for humans to be on mars but he also said it takes 20 years for a solar sail to melt the ice and we haven't even started that yet.

    Liar liar - There is no escape from earth and the punishment that is coming on those who hate Yahuah and his Torah. He will destroy this earth and these wicked liars and he has prepared a new earth for those who love and obey him. Have you not woken up to the plagues that he has promised which are coming Listeriosis - Pork To Eat Or Not To Eath

    At least four NASA astronauts believe extraterrestrials are real and are contacting us so I guess they could also believe the moon landing was real

    Mr2TIMOTHY4V2   3 days ago

    NASA is science fiction. NASA THEMSELVES is telling you escape velocity is currently not possible for a spaceship "An Endless Cycle : escape velocity is one of the biggest challenges facing [CONTINUOUS TENSE] space travel. The vehicle requires an enormous amount of fuel to break through Earth's gravitational pull. All that fuel adds significant weight to the spacecraft, and when an object is heavier, it takes more thrust to lift it. To create more thrust, you need more fuel. It's a cycle that scientists are hoping [CONTINUOUS TENSE ] to resolve by creating lighter vehicles, more efficient fuels and new methods of propulsion that don't require the same ingredients to attain great speeds." They then immediately CONTRADICT THEMSELVES by saying this : "That cycle of speed, fuel and weight was a primary reason the Saturn V rocket that took the first astronauts to the Moon was SO LARGE." If it was so large then it would need more fuel and if it needed more fuel it would be larger - do you see how they contradict their "ENDLESS CYCLE" admittance. (reference NASA-Escape Velocity Fun and Games) I think the key word is "Games" that NASA has been playing with the public.

    Even if we terraform mars and build civilization there. We eventually have to move again due to the moon crashing in mars.
