Q & A
Why is Mars considered a 'disappointing hellhole' for human habitation?
-Mars is considered a 'disappointing hellhole' because it lacks the necessary conditions for human survival, such as a breathable atmosphere and soil to grow food. It also has high levels of radiation due to its thin atmosphere.
What is the concept of terraforming Mars and why is it considered possible?
-Terraforming Mars involves transforming the planet's environment to make it habitable for humans. It is considered possible because, on a time scale comparable to the construction of ancient monuments, humanity could address Mars' issues by first exacerbating them with methods like using lasers to create oceans of lava.
What are the main components of a suitable atmosphere for Mars similar to Earth's?
-A suitable atmosphere for Mars would consist of 21% oxygen, 79% nitrogen, and a small amount of CO2, maintained at an average temperature of 14°C and under 1 bar of pressure.
How did Mars lose its oxygen-rich atmosphere billions of years ago?
-Mars lost its oxygen-rich atmosphere due to ultraviolet rays breaking down the atmospheric gases, followed by the loss of oceans to solar wind, which swept away the remaining atmosphere.
What is thermolysis and how does it relate to freeing gases on Mars?
-Thermolysis is a process that occurs at extremely high temperatures, similar to those on the surface of the Sun. It can be used to reverse the reactions that lock gases away in Mars' minerals, by melting the planet's surface to release oxygen and carbon dioxide.
What role do lasers play in the terraforming process of Mars?
-Lasers are proposed to be used in orbit around Mars, aiming their beams at the surface to melt it and release trapped gases. This would help create an atmosphere and potentially form oceans and rivers.
How would the process of melting Mars' surface with lasers affect its appearance?
-The process would cause the skies to be filled with storms, the ground to glow red-hot with lava flows, and laser beams to leave bright trails. After the lasers pass, the ground cools quickly, and a 'snow' of solidified elements like silicon and iron would fall.
What is the source of nitrogen needed to make Mars' atmosphere similar to Earth's?
-The nitrogen needed for Mars' atmosphere would come from Titan, a moon of Saturn, which has a thick atmosphere composed almost entirely of nitrogen.
How would life be introduced to Mars after creating a breathable atmosphere?
-Life would be introduced by seeding the oceans with phytoplankton, which would form the base of an aquatic food chain. On land, plants native to volcanic islands on Earth would be introduced to the nutrient-rich soil created by the terraforming process.
What is the final challenge for Mars' long-term habitability mentioned in the script?
-The final challenge is creating an artificial magnetic field for Mars to protect it from solar radiation and cosmic rays, as its core does not produce a natural magnetic field.
How would an artificial magnetic field be created for Mars and where would it be located?
-An artificial magnetic field could be created using a superconducting ring powered by nuclear facilities, located at the Mars-Sun L1 point to deflect the solar wind and protect the new atmosphere.

🌍 Transforming Mars into a Livable World
Mars is currently inhospitable for human life, lacking the necessary atmosphere and protection from radiation. However, through terraforming, we can potentially transform it into a habitable planet. This process involves making the planet worse by turning it into a molten state with powerful lasers before improving it. Terraforming Mars is challenging but possible within a few generations if humanity decides to expand into space.
🔬 The Challenges of Terraforming Mars
Mars' atmosphere is too thin, and the planet has no soil to grow plants. To make it habitable, we need to create an atmosphere similar to Earth’s, with 21% oxygen and 79% nitrogen, and a temperature of 14°C. This involves creating oceans and rivers, weathering the ground into fertile soil, and establishing a protective biosphere. A significant challenge is producing a breathable atmosphere, which requires melting Mars' surface with powerful lasers.
💥 Using Lasers to Melt Mars
Mars had a dense atmosphere billions of years ago, which was lost due to solar wind and ultraviolet rays. To recreate it, we need to melt Mars' surface using lasers to release trapped gases like oxygen and carbon dioxide. This process would involve a continuous, solar-pumped laser array in space. The lasers would melt the surface, causing dramatic transformations and releasing water vapor to form shallow oceans.
🌧 Creating a New Atmosphere on Mars
Continuous lasering would result in a molten surface and a new atmosphere. The process would take about 50 years, with melted surface layers releasing enough oxygen. This would create a stormy and red-hot environment, but eventually, clouds would form, and rain would wash out harmful gases, forming shallow oceans. The final atmosphere would be nearly 100% oxygen, requiring the addition of nitrogen for safety and habitability.
🛰 Importing Nitrogen from Titan
To create a breathable atmosphere, we need to import nitrogen from Titan, Saturn’s moon. This involves constructing automated factories on Titan to compress its atmosphere into liquid form, then transporting it to Mars using mass drivers. This process could be completed within two generations and would significantly contribute to making Mars' atmosphere similar to Earth's. Terraforming Venus could also provide additional nitrogen.
🌱 Establishing a Biosphere on Mars
Creating a stable biosphere on Mars involves seeding the oceans with phytoplankton, followed by zooplankton and fish, to establish an aquatic food chain. On land, plants need nutrient-rich soil, which can be created by breaking down lava into mud and mixing it with fungi and nitrogen-fixing bacteria. Volcanic island plants would be introduced first, followed by a variety of other plants, insects, and animals, forming a self-sustaining ecosystem.
🛠 Maintaining Mars' Ecosystem
Maintaining a stable ecosystem on Mars requires careful balance. Plants must not grow too quickly or die out too fast, as this could destabilize the environment. The new biosphere needs ongoing maintenance to ensure it doesn't collapse. It will take hundreds to thousands of years for Mars to become a stable and habitable environment for large human colonies.
🛡 Protecting Mars with a Magnetic Field
Mars lacks a natural magnetic field, which is crucial for long-term habitability. To protect the new atmosphere and future populations, we need to create an artificial magnetic field. This can be achieved by constructing a superconducting ring at the Mars-Sun L1 point, deflecting solar wind away from Mars. This solution would ensure Mars remains protected and habitable for centuries to come.
🚀 A New Home Among the Stars
Terraforming Mars requires substantial resources and time, possibly taking up to ten centuries. However, it would be a significant achievement, creating a new home designed by humans for humans. This endeavor represents the first step towards humanity's future among the stars, transforming Mars into a livable planet with air, water, and food available for large human colonies.

Mars is a disappointing hellhole lacking practically everything we need to stay
alive. It looks like we’ll only ever have small crews spend a miserable time hidden underground.
Except, we could terraform it into a green new world. But to solve the planet’s problems,
we first need to make it worse and turn it into oceans of lava with gigantic lasers.
This isn’t a far-fetched science fiction tale. Terraforming Mars is possible, on the kind of
time scale our ancestors built great monuments in. If humanity solves some of its pressing
problems and ventures into space to expand into the solar system, this may not be that far off.
Ok. So how do we terraform Mars quickly? Well, It’s complicated.
Mars is dry and has no soil to grow anything. Its atmosphere is too thin to breathe or protect from
radiation, giving you a high risk of cancer. So to turn it into a new home for humanity,
we have to give it a proper atmosphere, similar to Earth’s. It should be made of 21% oxygen,
79% nitrogen and a tiny bit of CO2, at an average temperature of 14°C and under 1 bar of pressure.
We have to create oceans and rivers and then the ground has to be weathered into fertile soil to
host living things. Then we need to install a biosphere on the surface and prevent it all
from being undone by installing protective measures that can stand the test of time.
It’s difficult. But a big laser makes it a lot easier.
Challenge 1: The Atmosphere
Some 4 billion years ago Mars had a nice oxygen-rich atmosphere and was home to vast
oceans and rivers. It held onto it for several hundred million years before it
got blown away. Ultraviolet rays broke down the atmospheric gases and then the oceans,
until they were swept away by solar wind. Today Mars is a dry, barren wasteland.
Luckily a sizable portion of the water is frozen in deep reservoirs and in the polar ice caps,
enough to create a very shallow ocean. And enormous amounts of oxygen are bound
as minerals in the Martian rocks, like the oxygen in the iron oxides
that give the planet its rust-red colour, as well as carbon dioxide in carbonates.
To free these gases, we need to reverse the reactions that lock
them away by using thermolysis, which occurs at temperatures as
high as on the surface of the Sun. In short, we want to melt Mars’ surface.
The best way to do that would be to put lasers in orbit aiming their beams down on Mars.
The most powerful laser today is the ELI-NP,
able to produce beams of 10 Petawatts of power, for a trillionth second.
To melt Mars we need a laser twice as powerful, that runs continuously. The easiest way is to use
a solar-pumped laser that can be powered directly with sunlight: At its core are metal-infused glass
rods that absorb energy and release it as a laser beam. If we build an array of mirrors in space,
about 11 times the size of the United States, we can focus enough sunlight onto them to melt Mars.
Let’s do it!
As the lasers hit the surface, about 750 kg of oxygen and some carbon dioxide emerge
from every cubic meter of rock melted. If we are efficient our lasers only need to
melt through the top 8 meters of the surface to get enough oxygen.
It would look terrifying. The skies would be shrouded in storms,
while the ground would glow red-hot, criss-crossed by currents of lava.
Tireless laser beams sweep over the landscape, leaving trails too bright to look at. After they
pass, the ground cools quickly. A strange snow falls: the ashes from all the elements
that solidify as they cool down, like silicon and iron. Mars is still a cold planet at this point.
A happy side effect of this inferno is that all the water in the polar ice caps and even
deep underground rises into the sky as hot steam, forming clouds that rain down over
the entire planet. They would wash out the nastier gases from the atmosphere,
like chlorine, and carry away harmful elements that accumulated on the surface. In the end, they
would form shallow oceans, saltier than on Earth. We might need to do an extra clean-up afterwards.
It would take about 50 years of continuous lasering to create our oxygen atmosphere. We
could use this opportunity to dig deeper in some places to create the basins for salty oceans or
rivers and spare some landmark features like Mons Olympus and Valles Marineris.
We’re not done though.
The resulting atmosphere is nearly 100% oxygen and only 0.2 bar. It’s hard to
breathe and very flammable. To make it similar to earth and a lot safer,
we need to add a lot of nitrogen, which Mars is lacking sadly. We have to import it.
The ideal source is Titan, a large moon of Saturn, covered in a thick atmosphere that’s almost
entirely nitrogen. We just have to move 3000 trillion tons from the outer solar system to Mars.
While that’s not easy, it is doable. To process that much of Titan’s atmosphere,
we have to construct giant automated factories, on its surface powered by our lasers to suck in
the atmosphere and compress it into a liquid. This gets pumped into bullet-shaped tanks,
which a mass driver shoots all the way to the red planet, where they explode and mix
with the oxygen. We’ve already been able to send individual missions to Saturn in just a few years.
With enough resources, it should be possible to complete the task within 2 generations.
Of course it would be much more convenient to have nitrogen left
over from terraforming Venus on the side: we explained this in detail in another video.
So, about a century after the start of the terraforming process,
we have a breathable atmosphere that has the right gases. If the liberated CO2
isn't enough to warm it up to temperatures we can stand, we just add some super greenhouse
gases. Mars at this point resembles a black marble from all the cooling lava,
spotted with growing oceans and red patches where the old surface remains untouched. It’s
still a wasteland, no better than a desert on Earth. We need to fill it with life.
Challenge 2: Biosphere
Installing a biosphere on a new planet is very difficult. Unexpected interactions
between species or sudden diseases can destabilise it to the point of collapse.
We would probably begin by seeding our young oceans with phytoplankton. Without competition,
it would bloom rapidly, filling up the oceans to become the bottom of an aquatic food chain.
They can be followed by tiny zooplankton,
then by fish. Maybe even sharks and whales. If things go well, life in the oceans will thrive.
Life on land is harder. Plants need nutrient-filled ground to sink their roots
into. But most of the surface is the congealed remains of lava and ashes. We could wait for
thousands of years for water and wind to grind it down into finer sands or try to do it manually.
But we want to be quick. And we have a big laser. Turning the beam on and off
in rapid succession would cause the ground to quickly heat up and contract, which breaks it
into smaller and smaller pieces. Add a bit of water, and you get a sort of dark mud.
Into this mud, we can mix fungi and nitrogen-fixing bacteria. They’re
able to absorb nitrogen and convert it into nitrate compounds to feed plants.
The first plants we want to bring are native to volcanic islands on Earth,
since they are perfectly suited to the laser-blasted Martian landscape.
Eventually, the enriched mud becomes the foundation for grasslands and forests. In
Mars’ lower gravity, trees can become very tall very fast. Their roots gather the nutrients
they need and then dig deeper to turn more rocks into soil, forming a self-sustaining ecosystem.
At this point we can slowly introduce more plant varieties, insects and animals. Not mosquitoes
though. The new biosphere needs to be maintained to prevent it from falling out of balance. If
plants grow too quickly and absorb too much carbon dioxide, the planet cools down too much.
If key species die out, we could see populations collapse faster than they could recover. On Earth,
other species would move in to fill the void, but our Martian biosphere is not as flexible.
It takes hundreds if not thousands of years before Mars becomes a stable environment.
But eventually the planet will have the potential to sustain large human colonies. With air,
water and food available, we can finally call Mars – black,
blue and green – our home. A giant, volcanic island in space.
Will it last though?
Challenge 3: The long-term future
There is a problem we haven’t addressed: Mars’ core does not produce a magnetic field, so it does
not have enough protection from solar radiation or cosmic rays. This becomes dangerous for the
long term health of Martian populations. So as a final step, we need an artificial magnetic field.
It doesn’t have to be huge like Earth’s. It
just needs to deflect the solar wind enough so that it doesn’t touch Mars.
The easiest way is to construct a magnetic umbrella far ahead of Mars that splashes the solar
wind to the sides. A big, superconducting ring powered by nuclear facilities is all it takes.
It would orbit at the Mars-Sun L1 point, keeping it constantly in
between the Sun and Mars and protect the new atmosphere. And that’s it!
Terraforming Mars would take some work, hefty resources and probably a century or
ten but it would be the first time we’ve lived in a home designed and
shaped solely by us and for us. A first step towards our future among the stars.
