Terraforming 101: How to Make Mars a Habitable Planet

Terraforming 101: How to Make Mars a Habitable Planet

Before we can journey to the stars, we must first go to Mars.

That’s Elon Musk’s philosophy, anyways – and just days ago he revealed new details on his ambitions to colonize the Red Planet, including sending two cargo rockets by 2022 and four rockets (two manned, two cargo) by 2024.

In 40 to 100 years, Musk suggested that up to a million people could live there.

Change of Seasons

As Elton John wisely noted, “Mars ain’t the kind of place to raise your kids”.

Indeed, the average temperature on Mars is −55 °C (−67 °F), dust storms are frequent and potentially deadly, and the planet has extremely low atmospheric pressure (about 1% of Earth). Because of the atmosphere and temperature swings, meaningful occurrences of liquid water on the planet’s surface are almost impossible. And while Mars is thought to have plenty of frozen water at its poles and in underground deposits, the logistics of tapping into these resources could be quite difficult.

In other words, for any meaningful and long-lasting human presence on Mars, we would likely want to alter the planet and its atmosphere to make it more habitable for human life. And while the exact mechanisms we would use to accomplish this are still up for debate, the basics behind what’s needed to achieve Earth-like conditions are actually pretty straightforward.

Terraforming 101

Today’s infographic comes to us from Futurism, and it details what might need to happen on Mars to make it more accommodating to human life.

Here are two steps we could take to get Mars into the “Goldilocks Zone”, where water is liquid – and harmful ionizing radiation like x-rays, UV rays, and gamma rays are not problematic.

Greenhouse Gases
One way to ward off harmful ionizing radiation is to add a thicker layer of greenhouse gases to the atmosphere of Mars. Such an atmosphere would also allows less heat to escape, meaning warmer temperatures on the planet.

Magnetic Field
A strong magnetic field on Earth is something else that makes life easier. Earth’s solid inner core, composed primarily of iron, creates this field when the planet spins – and it deflects cosmic rays and other harmful types of radiation.

One interesting solution to solve this problem on Mars would to have a magnetic field generator in front of the planet at all times, deflecting any such rays coming from the sun.

The Realm of Possibility

While terraforming is still a mixture of theory and science fiction at this point, we do know some of the major problems that have to be solved for attaining a habitable environment – and it will be interesting to see how plans around Mars develop as the prospect of colonization becomes more real.

You need to live in a dome initially but over time you could terraform Mars to look like Earth and eventually walk around outside without anything on. … So it’s a fixer-upper of a planet.

The United States is home to more than 46 million immigrants, constituting approximately 14% of its total population.

This graphic displays the top 25 countries of origin for U.S. immigrants, based on 2022 estimates. The data is sourced from the Migration Policy Institute (MPI), which analyzed information from the U.S. Census Bureau’s 2022 American Community Survey.

In this context, “immigrants” refer to individuals residing in the United States who were not U.S. citizens at birth.

Mexico Emerges as a Leading Source of Immigration

Mexico stands out as the largest contributor to U.S. immigration due to its geographical proximity and historical ties.

Various economic factors, including wage disparities and employment opportunities, motivate many Mexicans to seek better prospects north of the border.

Mexicans are followed in this ranking by Indians, Chinese, and Filipinos, though most immigrants on this list come from countries in the Latin American and Caribbean region.

On the other hand, only three European countries are among the top sources of U.S. immigrants: the UK, Germany, and Ukraine.

Immigration continues to be a significant factor contributing to the overall growth of the U.S. population. Overall population growth has decelerated over the past decade primarily due to declining birth rates.

Between 2021 and 2022, the increase in the immigrant population accounted for 65% of the total population growth in the U.S., representing 912,000 individuals out of nearly 1.4 million.
