Earth 2.0 We’ve spent a lot of time here on Earth; rather, all of it. We’ve grown so much: learning to walk, talk, make friends, build cities, start wars, and make bombs that can cleanse entire planets of life. This is our home. Sadly, we can’t live here forever. The concept of expanding our domain isn’t just about exotic Martian vacations or low-gravity sports. Earth may not be habitable forever. The ever-impending “consequences” of climate change, nuclear war, and a slew of astral natural disasters threaten the existence of all life on Earth. It’s time to take a rocket ship out of the nest and on to the next planet, Mars. As the second step in our next frontier, this big red dot in

The contents of the air, unmitigated by respiration and photosynthesis, are too disproportionate to support any kind of animal life, such as ourselves. As it stands today, the Martian atmosphere is composed of 95.3% Carbon Dioxide (Bonsor). As the Poles begin to melt and the top layer of dry ice sublimates, that amount of CO2 will increase exponentially. Fortunately, as fore mentioned, this is the desired process for the completion of the terraforming; however, we cannot survive in these kinds of gaseous conditions. Once the CO2 has done its job of creating a runaway greenhouse effect, the increased climate, and the presence of water, should allow for the survival of photosynthetic life. With this now possible, we can begin to turn all of that CO2 into oxygen through photosynthesis. Radiation from the sun, however, is still a concern to any life on the Martian surface due to a lack of an ozone and magnetosphere. Rebecca Slotnick believes she may have discovered the solution to this problem. Slotnick ran across some information mentioned by Robert Richmond of NASA’s Marshall Space Flight Center that a bacterium named Deinococcus Radiodurans, classified as an extremophile (bacteria that thrive in …show more content…
Mars is speculated to have had an extremely similar climate to Earth’s many billions of years ago (“Water on Mars”). the reason it has progressed to the state it’s in now is because of its weak magnetosphere. Without this planet-sized magnetic shield, Mars has no way of blocking solar winds from stripping it of its atmosphere. We need to find a way to restart the planet’s magnetosphere to prevent the new atmosphere that we’ve created from suffering the same fate that it realized many astronomical timelines ago. Over a period of eons, lighter molecules such as oxygen and water flew off the face of mars and out into the Oort cloud and beyond. Most large celestial bodies have enough mass to compress and heat its core. This molten metal core moves around in ways that science doesn’t quite understand yet; but, we do know that this flow causes an electromagnetic charge. This process of “rotating, convecting, and electrically conducting fluid” is called the dynamo theory (“Dynamo Theory”). A contributing factor to the loss of the Martian dynamo is its lack of a moon. Here on Earth, tidal forces between us and the moon pull and morph the shape of the Earth causing our mantle to churn. This relentless gravitational stirring causes the mantle to have a constant flow, called convection currents, that is conjectured to contribute to the charging of our magnetosphere through the dynamo effect. Mars, lacking a
