We will be a space civilization soon !

We will be a space civilization soon

By the development of technology, people will migrate from one planet to another. Even though we know, we can still see such a thing only in a sci-fi film.

A Russian astronaut Nikolai Kardashev introduced three types of civilizations in 1964;

   1) Type I civilization – Civilized beings consume the maximum amount of energy equal available to its entire planet(10¹⁷ watts for Earth)

     2)Type II civilization – Civilized beings consume the power of an entire  planetary system

      3) Type III civilization – Civilized beings consume the power of an entire galaxy

   4) Type IV civilization – Civilized beings consume the power of its own super cluster of galaxies

So, according to Nikolai Kardashev, we are not even a Type I civilization. Human civilization as of 2018 was producing around 18.4 Terawatts of power, placing us on just over 0.6 on Kardashev scale. According to scientists it will take 100 - 200 more years to become Type I civilization. But this is the decade we are living. Elon Musk’s SpaceX has already begun the initial steps towards the Type I civilization. After the Crew-2 mission, Musk said, "It’s been half a century after the people went to the moon. It's been a long time. We have to build a ‘Moon base’ on the moon. We have to become a space civilization by creating a city on Mars.”

The primary requirement for space travel is transportation. SpaceX’s ‘Starship’ is being built specially for this purpose and they have been able to send it at a height of 10 km and land it successfully. SpaceX is preparing to send the starship into space orbit for the first time during the next test. The specialty of this case is the use of ‘Raptor engines’ instead of the Merlin-1D engine used in SpaceX's Falcon rocket. Specialty of Raptor engines use methane (CH₄) as a fuel instead of hydrogen(H₂). The main reason for the use of methane is the ability of the ‘Sabatier process’ to produce methane on Mars using carbon dioxide (CO₂) and ice on Mars. Once the starship is complete, it will be able to land on the moon with a single refueling and return to Earth, as well as land on Mars. But in order to arrive back to Earth, fuel must be produced on Mars. Researchers at SpaceX are currently conducting various experiments on produce fuel on Mars.

Mars is about 225 million kilometers from Earth. It’s atmosphere is primarily composed with carbon dioxide (CO₂), nitrogen (N₂), and argon (Ar). So, by compressing the atmosphere of Mars, it is possible to grow plants on it. Mars's gravity is about 38% of Earth, and a Mars day is very close to an Earth Day. Therefore, Mars is an ideal planet and the closest planet to Earth to establish a habitation on another planet.

Do you think that you can step on Mars? Perhaps in another life time. Maybe we will born on Mars next time. How cool is that 😍
