Part 1: Mars Analysis

Is it possible for life to have ever existed on Mars or for man to colonize Mars? Scientists at NASA are leading us to believe that both are true. Are they true? Let's see.To answer these questions, we will use science to analyze and compare three different planets. Earth, Earth's moon, and Mars.

Mars is regularly referred to as Earth's sister planet to imply that the two planets are close enough in size to have the same physical properties and, since Earth can support life, then so can Mars.

But...Mars is actually closer to the size of the Moon (our moon is the fifth largest known moon in our universe.) We know that the moon cannot support life because it does not have enough gravity to maintain enough of an atmosphere to have life. If we were to pipe all of Earth's atmosphere to the Moon, it would all float out into space within a relatively brief period of time.

Without an adequate atmosphere, we cannot have water in a liquid state. Atmospheric pressure is required to keep water in the liquid state. We have known for over half a century that liquid water in a vacuum instantly either vaporizes (boils) or freezes. Without adequate atmospheric pressure, water can only exist as either a gas or solid.

Without liquid water, you cannot have life because of the very unusual properties of water which make life possible and are not found in any other fluids. Therefore, life cannot happen or evolve on the Moon.Mars is only 17% the size of Earth which means that Earth is more than five times the size of Mars.

This is a huge difference for planets that are supposed to be sister planets. Mars only has 38% of Earth's gravity which means that Earth has more than two and a half times more gravity than Mars.

This is a crucial difference and the main factor which will tell us whether or not life can exist on Mars or if we can colonize Mars. The Moon only has 16.7% of Earth's gravity. Mar's gravity is only a little more than twice that of the Moon's gravity. As you can see, Mars is much more a sister of our Moon than Earth. It gets better.

The Moon does have a little atmosphere but so little that we say it has none. Mars has a similar problem to the Moon. With less gravity, it is easier for gas to float away from a planet and, therefore, the planet cannot maintain as much or as dense of an atmosphere. Mar's atmospheric pressure is between four and five millibars at the surface. 1,000 millibars equals one bar of atmospheric pressure which is Earth's atmospheric pressure.

Mars' atmosphere is less than 5/1,000 that of Earth's atmospheric pressure. This is much closer to the Moon's atmospheric pressure.The gravity on Mars is not adequate to maintain much of an atmosphere for very long. It cannot maintain enough atmosphere to have water in the liquid state.

Liquid water released on Mars will either vaporize or freeze very quickly. The only way you can have liquid water on the surface of Mars for even a brief period of time is if volcanic activity were to quickly release enough steam into the atmosphere to force the water beyond the point of saturation for the atmosphere and forcing water to condense. Enough of this water vapor would quickly float away from Mars to return it to the state to where liquid water would quickly either vaporize or freeze.

Mars cannot maintain water in the liquid state required for life for even a million years, much less for long enough for life to happen and evolve.A problem caused by this very thin atmosphere is that there is not enough atmosphere on Mars to keep the heat created by sun light striking the surface from quickly radiating out into space.

This problem is made even worse because Mars is enough further from the sun so that much less light hits its surface and there is less surface to heat up the atmosphere. Because of this, the temperature on Mars remains well below freezing (average temperature is -55 F) except during the summer at the equator during the day time when it can briefly reach up to 80 degrees F.

This further decreases the possibility of ever having life on Mars. An atmosphere is crucial to having the conditions required for life which means that an adequate gravity is also required to have life happen and evolve on a planet. A planet has to be just the right size to be able to have life on it. Earth is the only planet in our universe which is the right size to have life on it.Then why is NASA telling us that we are looking for life on Mars.

I suggest two possible reasons.

First, a number of the most influential scientists are evolutionists who are hoping to find evidence of life on Mars to keep their religion of evolution alive as I stated in the page on "What Is Science?" and they are so desperate they are willing to ignore what science tells them should be the case.

Second, maybe they don't feel that Americans will spend the billions of dollars to explore Mars for scientific curiosity but will spend the money to search for possible life. In other words, it keeps the money coming in to pay their salaries. I believe that it is probably a little of both.
