Venus Vs. Mars. Which is perfect for terraforming?
http://lupuvictor.blogspot.com
Unlike Venus, which rotates once every 243 Venusian hours on its axis, Mars revolves once every 24 Martian hours and 37 min, which is very similar to the Earth. The only thing that Mars is in disadvantage in comparison to Venus, is that it has a diameter of 6.792 km, which is small compared with the Earth and Venus, these latter two being similar in sizes. Venus’ diameter is 12.092 km (only 650 km less than the Earth).
If you were to ask which of the two planets would be suitable for any life form, which would you choose? My guess is that Mars. This planet with an atmosphere, be it thin, consisting of carbon dioxide, is more like ours: it is not always covered by clouds like Venus, and temperatures oscillate between -143 ° C and 35 ° C, and the average temperature of Venus is 480 ° C.
Besides this, I think it’s easier to live in cold weather than hot. Here on Earth we know that it is much easier to protect yourself from cold than warm. When it’s hot, you can undress yourself all naked but you can not escape the hot weather. If it’s cold, you can wear thicker clothes and adjust your body temperature.

For Mars we represent aliens. We can change the future of this planet, because we got right on it thanks to our technology.
We know that there are not life forms on Mars and do not even know for sure if this planet hosted this in the past, but we know that we have the ability to do it, once we studied it and we have got there. How? I think it’s simple. We discovered life forms on our planet, that can live in very difficult conditions, similar to those on Mars. It is the microscopic microbial life: small creatures called bacteria and archaea.
A type of photosynthetic bacteria called cyanobacteria can form the first molecular oxygen in the atmosphere, which could raise about 10% oxygen on the planet, allowing ozone and oxygen to form, using creatures to evolve.
In future missions, we can transport these bacteria there to monitor their behavior in that environment. I think we’ve reached a level of knowledge of the red planet, in which we can experimenting various ways of how we can revive the planet. Slowly, through long programs, we can terraform Mars into something unrecognizable.

We all know that the Apollo astronauts when returning from the Moon, were taken first to a “cell” in quarantine. This is because they went an alien environment, where they could borrow various substances which were not on Earth. This practice continued for two more Apollo missions, Apollo 12 and Apollo 14, before it was proven that the Moon is barren of life. Later, the quarantine has been cancelled.
Same, but conversely, it can happen on Mars, and exclude quarantine. There we can deliberately “infecting” the planet with microbial biological factors that can transform it. In a very long process, these substances can act as a “disease” called life, which may cover the entire planet. Maybe Mars really needs those substances sent from here. Have you thought of that?
Either way, I think with manned base there, could be more easily there than on the Moon, where the atmosphere is totally absent.
How hard is to terraform Mars?
Other rocky planets with an atmosphere besides Mars, in our solar system are Venus and Earth. Venus is closer to the Sun than we are, so it’s a hot planet, and Mars is farther from the Sun than we are and so there is much cold than here. Earth therefore lies between the two planets, Venus and Mars, both with extreme temperatures, but Earth with temperatures just right for life.
To reach Mars would take 6 months traveling with today’s technology. In an hermetically closed module, would be transported microbial creatures found on our planet that could survive on Mars. I’m surprised that so many rover missions on Mars, but no microorganisms were transported to be left there. This would be essential to discover if indeed this planet can sustain life. I think maybe NASA is counting on finding life there, without external influences, because after that, if it finds something, we will not know whose it was. This compares with the question: whose is my child?
It is clear that where there is no water, a plant is not good for anything, it dries and dies. A mission of this kind would cost millions to no results. But if we consider other methods, can we have a result. I think even of the terraforming from inside.
I do not know if we have created the conditions on Mars, here in laboratories on Earth. It should be built some large ermethical spaces,, in which there has to be soil, air and temperatures to match those on Mars. I do not think NASA does not know these things with so many missions performed on the red planet.

We have the necessary data for creating a Martian environment, as it was created a Moon environment for Apollo astronauts, but I think this task would be more complex. Creating environment of Mars, involves in my opinion, a very hard work, because you have to create a certain amount of air substances, not as the lunar vacuum.
