1.   Exploration

During the colonial era, different nations sent voyages to new lands, which they could call, home. People would go on voyages into the ocean without even knowing where they were going. Many of the voyagers lost their lives while on a search for new lands. America was discovered during one such voyage led by Christopher Columbus.

2.   Earth’s Impending Doom

The population of the world is increasing with each passing day and resources are stretched thin. Global warming and pollution are making the world uninhabitable and then there is a cosmic danger of impending doom one stray asteroid could wipe out humanity as it did with the dinosaurs. A gamma-ray burst from Super Nova could destroy the ozone layer and make the world uninhabitable.

3.   A New Home for Humanity

If humanity wants to survive, we must find a new planet, which we could call home. The initiative started when NASA first landed a man on the moon. Humanity has been exploring space since 1957 when Soviets launched its first satellite in space. After that, the race to moon started as both countries tried to land the man on moon and NASA successfully landed the first man on the moon.

4.   Second home

Since then all the space agencies of the world are trying to find habitable planets. Various missions to land man on Mars have been proposed by different space agencies. If humans are to survive then they must find a new home for themselves. “SpaceX Mars Transportation infrastructure is program launched by a private space agency (SpaceX) is a mission which is set to put the first human on earth by 2024.

5.   Plans to Put man on Mars

Traditional fuel would be used to propel the space shuttle towards Mars. Elon Musk the company’s CEO revealed that a local fuel plant would be established on Mars which would synthesize methane on the planet. That methane would be used as a fuel for the rocket when it makes the journey back to earth.

NASA is planning its own mission to send a manned mission to Shuttle by 2035 and the preparation for the mission would be done before the arrival of a manned mission. Robots would be used to dig an underground shelter for astronauts. The underground shelter will remove the problem of establishing surface sheltering and will keep astronauts safe from radiations.

6.   Difficulties faced

The first thing that human need to counter on Mars would be radiation. Mars have a thin atmosphere and have no magnetic field which makes it vulnerable to radiations. So early humans would have to live underground in order to survive. The second problem would be gravity.

Mars’s gravity is lower than earth. This might seem a small problem but it poses a great threat to the astronaut. Humans bone density decreases as they live in a low gravity environment. The bone density is directly proportional to gravity. If a person lives in a gravity-free environment his bone density would decrease to the point where he won’t be able to stand in earth’s gravity. Increasing gravity might be the biggest problem because at present there is no proved technique that can stimulate gravity other than actual mass acceleration.

7.   Colonization of Mars

If the trip is one way then the problem of gravity can be ruled out because the inhabitant would have to come back to earth again.

Colonization of mars remains to be seen but the idea has captivated many fiction writers, which shows us a future of Mars’s colonization. Maybe in time, we might be able to terraform the whole planet to our advantage but this is all just speculation at this point and it remains to be seen whether human might colonize Mars or not.
