Could humans live on Mars?
NASA plans to send humans to Mars within 20 years.
Will technology enable us to live permanently so far from Earth? Will we want to?
Watch: Consider could a human be born on Mars?
Watch a short intro to the debate: will a human ever be born on Mars?

After Earth, Mars is arguably the most habitable planet in our solar system.
Many see life on Mars as the best way to extend humanity's existence.
The soil and atmosphere on Mars contain many elements crucial to life, including carbon, oxygen, hydrogen, and nitrogen, and the polar ice caps appear to contain water.
However, the journey to Mars is a treacherous six-month expedition of over 50 million km—and that’s when it’s nearest to Earth.
Mars’ atmosphere is 95% carbon dioxide, and the average temperature is -60˚C.
So humans would need air tanks and heated space suits to survive when outdoors.
Scientists are working on ways to transform the atmosphere on Mars to resemble the conditions on Earth—this is called terraforming.
One idea is to build giant space mirrors that will reflect the sun and increase the bitterly cold temperatures through global warming.
In theory, it is possible for humans to inhabit Mars, but it will be very difficult.
Do you think a human being will ever actually be born there?
Did you know?
When Mars’ orbit comes closest to Earth (every two years), Mars is still 100 times further away than the Moon.
Discuss
Controversial issues in science make for great discussion topics. The following video shows students your age expressing a range of opinions about whether or not a human will ever be born on Mars. Get together with your friends and discuss the issue!
Listen to secondary students debating the issue and join in the debate. What do you and your friends think?
Will a human ever be born on Mars?
Many see life on Mars as the best way to extend humanity's existence.
What would have to happen on Earth for us to actually go to Mars?— The world ending.
The only time Earth would really be in the state where you’d have to move is when it’s like apocalyptic, you know?
It would have to be uninhabitable.
Extreme conflicts or pollution would have to rise up on Earth, you know, make it a dying planet almost.
The journey to Mars is a treacherous six-month expedition of over 50 million kilometres.
Imagine having to stay together for six months in the same rocketship.— That six-month journey, it would be hell.
What sort of stuff would you take? Is there anything about Earth as a planet that you would take really?— Emm, I’d probably take my friends or someone to keep me company.— I would take food, drink, medical supplies.
You would need to bring like trees and stuff, so you could get the oxygen.— Yeah, get more oxygen out.
And I feel like it would be really weird and almost unnatural for a baby to be born in this completely new environment.
But the people that are already there, I don’t think they’ll want to give birth to babies anyway because there will probably be a lack of oxygen in the beginning when it’s actually started because they don’t have everything clarified yet.
When technology advances so much that we’ll be able to live on other planets—maybe even not just Mars.
We would have to change the whole planet.
So we’re just turning it back into Earth, so all we’d be doing is just moving from one planet to another to another to another to another.
Did you know?
Currently, a journey to Mars would take at least six months. The atmosphere on Mars is 95% CO₂ and the average temperatures below -50 °C.
Decide
This video contains some final opinions. Have you come to a decision yet? What are your reasons?
Watch video journals of four people's points of view. What's your opinion?
A baby could possibly be born on Mars, but I think it would be done maybe in the year 3000 or 4000, ’cause they would have to pay for the machinery to travel up to Mars, as well as the machinery to colonise it.
I think a human baby will be born on Mars because, since that will mean humans will be living on Mars, so if they’re living on Mars and surviving on Mars, I don’t see why they won’t be able to reproduce there and bring in new life.
If you're going off to Mars and everyone's changing planets and terraforming and everyone’s actually able to live there, then yeah, it's possible.
But since technology advances a lot, maybe there would be a possibility of a strong bio— more efficient solar energy—then yes, maybe, there could be hospitals suitable enough for a baby to be born on Mars.
Did you know?
Probes have found evidence of ice on Mars, and many of the elements that would be needed to sustain life.
