Beyond earth: pt 2 Terraforming Mars and Venus
At this point they can begin the terraforming process. Earth can digitally send plans to build sulfur hexafloride plants the most powerful greenhouse gas known to science, breathing it actually has the opposite effect of helium, there are youtube videos on this. With the planet warming the atmosphere will get a bit thicker since the CO2 won’t freeze into dry ice at night. Ice caps will start melting, releasing water. Wel will start growing lichen and then other drought tolerant plants and microbiota, using algae produced fertilizer to convert the soil to arable use.
We will have a factory dedicated to building balloons, that reflect heat back to the plan
et’s surface, as clouds will be rare in the beginning. They will also act to replace the missing magnetic field and block absorb or reflect some of the harmful cosmic rays, using gamma or high energy light to power them, they will have material that traps protons, alpha and beta ray, stripped helium and electrons from solar winds and puts them back into the atmosphere to replace Hydrogen and Helium removed by solar winds removed 3-4 billion of years ago without a magnetic field. I will guess that in the next 50 years, synthetic materials will easily be embedded with solar powered proton pumps and ion channels that bacteria have, to pull hydrogen and helium from the air when balloon pressure gets too low and eject it when the pressure gets too high.
The martian ecosystem will be the biggest experiment in evolution ever seem. Every animal we bring will be small. Tiny dogs, cats, rabbits, pygmy goats, rodents, tea cup pigs, insects. Once they become feral in their new tree filled forests and fields, we will see evolution pick up the pace and fill niches faster than we could have imagined. Giantism in some species could evolve in a few 100 years if there was enough resources. We may just put temporary suppressor genes or methylations though and create runt members of a species for transport and then suppress those suppressors working their way up slowly by generation so they can bear full sized offspring of their species. At that small size we may also temporarily speed up their fertility and gestation rates to allow for a larger new stock population.
Humans may also have the first speciation event since Homo erectus or earlier. 1/3rd gravity may very well affect human fertility, and select for humans that can carry children to term in low gravity. We may grow longer and with less muscle mass but larger cardiovascular systems for the thinner atmosphere that at full strength may still feel like a very high altitude . A martian visiting earth will require a grueling workout routine before and on the way to earth just to be able to function in earth’s gravity and air pressure.
People will live on the equator, currently the equator has a high temperature of 80F, though that number will increase to 90 or 100. Small changes to equatorial temperatures causes extremely large temperature rises on the rest of the planet. If we were able to collect enough hydrogen or just mine asteroids for water and hit the planet with ice, a giant ocean could exist on the north half of the planet and the entire equator would be tropical beachside property.
Of course the moon will be our first attempt to build these modules. Although everything but the 2 bioreactors can work on the moon. The bioreactors may have to be built on a carbon and water rich asteroid carried to circle the moon. NASA is hoping to do so in the next ten to 20 years. Space elevators will be even cheaper on the moon with such low gravity, so the oxygen and hydrogen from split water will easily get us from the asteroid to the space elevators cheaply with supplies and produced chemicals. There will be little to no point in terreforming the moon, and the moon with stocks of helium 3 will be the best place to build antimatter plants. We may terreform it in its tiny atmosphere to have a small amount more oxygen so getting stuck out on the surface won’t be as deadly, but thats the best we will be able to do without tech we are unaware of at the moment.
The we will move on to Venus, or once we have the modules built on the moon we may do them in tandem with mars. the temperature and pressure on Venus is too dangerous to live on the surface, but a balloon filled with one atmosphere of air can float just fine among the clouds so we will set up balloon based outposts and colonies later on on Venus. We will have to cart a few mineral rich asteroids into Venus’s orbit to provide metal that is too dangerous to reach the surface. Rocket launches and landings will be similar to space ship one and 2 just without the white knight and replaced by ballloon/jet hybrids so the amount of fuel needed to get from Venus to and from the asteroid will be much less than it would be from the surface.
The robot mining group the refinery and maybe the machining plant will be located on the asteroid to ensure the least amount of wasted material will have to be sent to Venus. The balloons used to heat up mars will be built on overdrive to cool down Venus. These balloon will be very long and thin and will turn sideways at night to allow heat to escape the planet, but block heat, radiation and solar winds from hitting the planet. I calculated depending on how much Earth feels like spending, it could take 50 to 300 years to build enough balloons to cool venus to a livable temperature at the poles. It may take 100 years or more to vent all of the trapped heat off, however I do not know the thermodynamics of planetary heat loss in this formula. Terraforming Venus has a lot more advantages to terreforming mars. Gravity is extremely close to that of earth requiring less body adjustment, and there a much larger area of land to live on. The equator will be so hot and dry that living in the interior of the continent Aphrodite would be suicide, but once we’ve collected enough hydrogen from solar winds and re ocean it, along the beaches might be fine. The Ishtar and Lada continents along the polls will be nice as well though they unfortunately will have the arctic-style nights long nights which will lead to some interesting evolution.
However there is the negative impact of a day lasting 2/3rds of an earth year and a year being even shorter than that, however by that time we will have had another 150 years of scientific exponential research under our belt and we may be able to use the geophysics to increase the spin of the planet, and get the core spinning again like in the really awful movie the core where they used 5 nuclear bombs but physicists calculated it would require around 120 of those bombs in different areas of the planet to work like that. Complicate it more by the fact that Venus spins backwards and may have been slowed down and lost its spinning core by exchanging energy with the sun so we would have to reverse the spin then get it up to somewhere near earth day speed. Until this happens I can see species following the long night, eating the freshly thawed carrion of animals that either got old or tired and the night winter caught them.
I’ve been wanting to do a post on this subject for a while but it wasn’t until the ideas of self-replication modules for colonies that I felt I would have enough material. I could go on and on about exciting futurism hundreds of year away but it can get into some serious tedium which is where I am at the moment. So I hoped you enjoyed and got you to look forward to the future, even if life extension doesn’t materialize in our lifetime and we don’t get to see or experience it. Take care!
