Mars: Mankind's Next Address?

 

    Mars has always been a subject of curiosity for humans.Scientists believe that if there is a possibility of life on any planet after Earth, it is Mars.

Let’s explore some of its exciting aspects:

1. Evidence of Water on Mars

    Water is essential for life. Evidence suggests that in the past, Mars had rivers, lakes, and perhaps even vast oceans.Even today, water is present in the form of ice at the Martian poles.NASA's rovers have also expressed the possibility of liquid water existing beneath the Martian surface.

2. Atmosphere and Life

    The atmosphere of Mars is much thinner than Earth's and consists of 95% carbon dioxide. There is very little oxygen. However, NASA’s 'MOXIE' device recently succeeded in producing oxygen from the Martian atmosphere, which will be crucial for future human habitation.

3. Could Microbes Exist There?

    Scientists are not looking for large animals or aliens on Mars; they are searching for microbes. Methane gas has been found in Martian soil, which on Earth is produced by living organisms. Therefore, it is believed that bacteria might still be alive beneath the surface.

4. Similarities Between Earth and Mars

The possibility of life on Mars is higher because it is similar to Earth in many ways:

• Length of Day: A day on Mars is 24 hours and 39 minutes, nearly the same as Earth.
• Seasons: Like Earth, Mars also experiences seasons such as winter and summer.
• Axial Tilt: Mars is tilted 25 degrees on its axis, while Earth is tilted 23.5 degrees.

Challenges of Human Habitation

If we go to live there, we will face several major challenges:

• Radiation: Mars lacks a protective magnetic field like Earth, resulting in very high levels of lethal radiation.
• Cold: The average temperature on Mars is as low as -60°C.
• Food: The soil contains toxic elements called perchlorates, making direct farming impossible.

Farming and Future Missions

How will farming work on Mars?

Martian soil, known as 'Regolith', lacks nutrients. To grow food, the following methods will be used:

• Greenhouses: Since open-air farming is impossible, glass domes or greenhouses will be built to maintain Earth-like pressure and oxygen.
• Hydroponics: This method of growing plants in nutrient-rich water without soil will be ideal.
• Fertilizer: Human waste can be purified and used as fertilizer.
• Light: Because Mars is far from the sun, special LED lights will provide the necessary energy for plants.

SpaceX Starship: The Martian Vehicle

Elon Musk’s 'Starship' is the most powerful rocket to date. Its key features include:

• Reusable: It can return to Earth and be reused, reducing space travel costs by 100 times.
• Capacity: It can carry more than 100 passengers at once.
• In-situ Fuel: To return, it will use Martian carbon dioxide and ice to create methane fuel.

Travel Time

    When the two planets are at their closest, the journey takes about 6 to 9 months. This opportunity only occurs once every 26 months.

A Self-Sustaining City

Architects are working on blueprints for a 'self-sustaining city:

• Vertical City (Nüwa): Homes will be carved into massive cliffs to protect residents from radiation and meteors.
• 3D Printing: Robots will build houses using local Martian soil.
• Energy: Power will be generated through vast solar farms and small nuclear reactors (Kilopower).
• Recycling: Water and air will be 100% recycled.

 

What Will Life Be Like on Mars?

• Your Weight: Martian gravity is only 38% of Earth's. If you weigh 100 kg on Earth, you will weigh only 38 kg on Mars.
• Blue Sunset: Due to fine dust particles in the atmosphere, sunsets on Mars appear blue.
• Lava Tubes: Humans may live in natural volcanic caves (lava tubes) for protection from radiation.
• Slow Internet: Communication with Earth takes between 3 to 22 minutes.A "Hi" on WhatsApp might get a reply half an hour later!
• Age: A year on Mars is 687 days. You would celebrate your birthday roughly every two Earth years!
