ClassX Video Lessons Youtube Channel Science Time Elon Musk Wants Mars’s Population to Reach 1,000,000 by 2050
Mars is often called the “Red Planet” because of its reddish appearance, which comes from iron oxide, or rust, in its soil. It’s the fourth planet from the sun and has a very thin atmosphere, making it a cold and harsh place. Despite these challenges, some people dream of making Mars a new home for humans.
Elon Musk, the founder of SpaceX, is one of the most famous people who wants humans to live on Mars. He believes that for humanity to survive in the long run, we need to live on more than one planet. This means figuring out how to travel to Mars and build a city that can support itself without help from Earth.
When considering other places in our solar system, Mars seems like the best option for a new home. Venus is too hot and has a crushing atmosphere, while Mercury is too close to the sun. The moons of Jupiter and Saturn are too far away, leaving Mars as the most practical choice.
Living on Mars won’t be easy. The gravity on Mars is only 38% of what we experience on Earth, which could affect human health. Mars also lacks a protective magnetic field, exposing its surface to harmful radiation. The atmosphere is mostly carbon dioxide, and temperatures can drop to a freezing -125 degrees Celsius in winter.
SpaceX is working on a spacecraft called Starship, designed to be reusable and capable of long missions. However, traveling to Mars is tricky because Earth and Mars align for a journey only every 26 months. Critics worry about the radiation astronauts might face on the trip, but Musk believes these risks can be managed with proper shielding.
Musk envisions millions of people living on Mars by 2050, creating a self-sustaining civilization. This would require a lot of people and resources to build the necessary infrastructure. The idea of colonizing Mars is becoming a serious topic among scientists, and we might see missions to Mars in the near future.
The dream of living on Mars is challenging but exciting. As technology advances, the possibility of humans becoming a multi-planet species is becoming more realistic. The 2020s might be remembered as a time of great exploration, similar to the moon missions of the 1960s.
Research more about Mars, focusing on its environment, atmosphere, and potential for human habitation. Create a presentation to share your findings with the class. Include visuals and explain why Mars is considered the best option for colonization compared to other celestial bodies.
Participate in a class debate. Divide into two groups: one supporting the colonization of Mars and the other opposing it. Use facts from the article and additional research to support your arguments. Discuss the feasibility, risks, and benefits of living on Mars.
In small groups, design a model of a self-sustaining Mars colony. Consider the challenges mentioned in the article, such as radiation, temperature, and atmosphere. Present your model to the class, explaining how it addresses these challenges and supports human life.
Imagine you are one of the first colonists on Mars. Write a diary entry describing your daily life, the challenges you face, and your hopes for the future. Use information from the article to make your entry realistic and engaging.
Role-play an interview with Elon Musk. One student acts as Musk, while others are journalists asking questions about his vision for Mars colonization. Prepare questions and answers based on the article, focusing on SpaceX’s plans and the future of Mars exploration.

[Music] Mars, a cold and unforgiving red desert, was named the god of war by the Romans due to its thin, almost airless atmosphere and the iron oxide in its soil, giving it a reddish hue. The fourth rock from the sun has often been referred to as “red and dead,” but could future generations call this red wasteland home? The colonization of Mars is not a new idea, but it has gained popularity in recent years, especially among notable scientists and thinkers.
One of these is Elon Musk, who envisions a future where humanity becomes a multi-planetary species. However, before we can dream about such a remarkable world, we must confront the many challenges associated with space travel. Perhaps the most daunting task will be addressing the differences between Earth and Mars.
There are fundamentally two paths for humanity: one where we remain on Earth indefinitely, leading to an eventual extinction event, and another where we become a spacefaring civilization and a multi-planet species. To achieve this, we need to figure out how to travel to Mars and create a self-sustaining city that could thrive independently.
Some may wonder why Mars is the focus. To put things into perspective, the solar system has limited options for becoming a multi-planet species. Venus, for instance, is a high-pressure, hot environment, making it a challenging option. Mercury is too close to the sun, and while moons of Jupiter or Saturn could be considered, they are much farther away. This leaves Mars as the most viable option.
Mars has only 38% of Earth’s gravity. A project called the Mars Gravity Biosatellite aimed to study the effects of Martian gravity on mammals but was canceled due to funding issues. While microgravity is known to cause health problems, it remains uncertain if Martian gravity would have similar effects.
Additionally, Mars lacks a magnetosphere, exposing its surface to solar particle events and cosmic rays, resulting in radiation levels that are 700 times higher than those on Earth. The atmospheric pressure on Mars is far below the Armstrong limit, which means humans would need pressure suits to survive. Since terraforming Mars is not a near-term solution, habitable structures would need to be built with pressure vessels similar to spacecraft.
The atmosphere is primarily carbon dioxide, and the temperature variation between day and night is significant, with winter temperatures near the poles dropping to -125 degrees Celsius. Despite these challenges, Elon Musk is determined to pursue the goal of making humanity a multi-planetary species, with hopes of a million people living on Mars by 2050.
Reusability of spacecraft is less applicable to Mars due to the Earth-Mars rendezvous occurring every 26 months. This means the spaceship can only be used roughly every two years, while the booster and tanker can be used more frequently. The SpaceX Starship system, currently under development, is designed to be a fully reusable launch vehicle, with the upper stage intended for long-duration missions.
Critics have raised concerns about the Starship’s ability to protect astronauts from ionizing radiation during Mars missions. Musk believes the transit time to Mars will not significantly increase cancer risk, and the lifetime cancer risk can be mitigated through shielding measures.
SpaceX has also explored the possibility of using Starship for sub-orbital flights on Earth, potentially connecting any two points in under an hour. However, no concrete plans have been announced for this application. Musk envisions a future where millions of people move to Mars, establishing a self-sustaining civilization and transforming the planet into an Earth-like world.
The first step in this plan involves building a self-sustaining civilization on Mars, which would require a significant influx of people and the establishment of transport infrastructure between Earth and Mars. It is fascinating that we are living in a time when these possibilities are becoming serious discussions in the scientific community.
Perhaps by the end of the decade, we will embark on missions to Mars, not because they are easy, but because they are hard. The 2020s may resemble the 1960s during the moon era, making it an exciting time to be alive.
