What seemed just a few decades ago to be the exclusive domain of science fiction is a serious goal for many space agencies and private companies: having humans walk on Mars and eventually colonize the planet. But is this really possible?
Mars, often referred to as the “Red Planet,” is an extremely cold and desolate world, with a thin atmosphere and intensive radiation. These are formidable challenges that any possible colony on Mars would have to overcome in order for it to be colonized.

The Harsh Martian Environment
One challenge for colonization is the hostile Martian environment. The planet has no global magnetic field. Its surface is bombarded with possibly harmful solar and cosmic radiation, to which any future human inhabitants shall be exposed. This is a serious health hazard.
Moreover, the temperature on Mars is as cold as -80 degrees Fahrenheit, while the atmosphere is made up of carbon dioxide, mainly; all these make it impossible for humans to survive without life support systems.
Sustaining Human Life
For man to survive on Mars, he has to create self-sustaining ecosystems for survival. This ranges from sophisticated life-supporting systems with the ability to recycle air, water, and waste. It will also be essential to cultivate food on Mars; in this regard, hydroponics or aeroponics may become viable. Since the Martian soil does not contain the necessary nutrients to support the growth of plants, obtaining suitable growing media is necessary.
The Journey to Mars
One more significant task at hand will be transporting humans to Mars. The journey itself will take several months and will put astronauts at risk from space radiation and the psychological stress of isolation. First and foremost, designing a spacecraft that will carry out the gigantic task of transporting humans together with adequate supplies for survival during its long journey is not an easy engineering task.
Economic Viability
Planetary colonization to Mars is a tremendously costly enterprise. Financing of this mega project will have to be seriously invested by governments, private enterprises, or jointly by both. Besides, in the long run, an independent economy needs to be built on Mars. The identification of such potential resources and the technologies for their extraction and exploitation will be critical.
Ethical Considerations
There are important ethical issues for Mars colonization. Is this a Pandora’s box that we should now open, given the serious problems facing Earth, from climate change to inequality? Some believe that by colonizing Mars, it could provide a survival plan for humanity; others argue it would siphon off resources better applied to more pressing global problems at hand. Though the challenges are enormous, the prospect of human colonization on Mars is beyond doubt-inspiring.
Increased research, technological development, and international cooperation mean that perhaps one day it will prove real. On the contrary, careful planning, ethical considerations, and realistic risk assessments should be taken into consideration while developing this objective.
