Have you ever worried about global warming? Have you ever got fed up with your mundane existence and wanted adventure? Have you ever been curious? If some of these apply to you then perhaps you should terraform another planet. There is a problem with that solution though, it’s quite a large undertaking for an individual. Perhaps we should leave it to one of those big organisations like NASA.
But can it be done? Yes, it can be done but there needs to be some very good reasons to do it. The obvious planet is Mars and this planet has been explored and talked about for a long time. Other planets and moons that have the potential-
Venus is to hot and has too much carbon dioxide. It seems, though, that one is linked to the other. Therefore sorting out the atmosphere would probably sort out the high-temperature problem as well. Venus would also need some oxygen added and there would have to be some sort of solar and cosmic radiation protection. This protection could come from a magnetic field but this would have to be produced artificially.
Europa, which is a moon of Jupiter, may be a good candidate as well. There may be water underneath the solid surface kept liquid by volcanic activity. Europa though is in the middle of a large radiation belt around Jupiter. This is not very good news for a human being and protection would be needed to prevent us poor frail humans being zapped and killed within about 10 minutes.
Mercury has a little potential, but has some disadvantages that make it a distant option. It has no atmosphere and is in the gravity well of the Sun, this would mean that it would take a long time to actually land on Mercury. It has a long day and would equal 176 of our earth days and this would make it quite uncomfortable for human inhabitants.
Titan offers some advantages, others don’t, it’s close to Terran atmospheric pressure and there is an abundance of nitrogen and frozen water but unfortunately, it sits in a radiation belt.
As you can see Mars is the favourite for colonisation in the near future with eventual terraforming.Initial .Stages of terraforming Mars could take several decades or centuries. Terraforming the entire planet into an Earth-like habitat would have to be done over several millennia. So, how are we supposed to transform a dry, desert-like land into a lush environment, where people, plants and other animals can survive and breathe?
NASA is currently working on a solar sail propulsion system that would use large reflective mirrors to harness the sun’s radiation to propel spacecraft through space. Another use for these large mirrors would be to place them a couple hundred thousand miles from Mars and use the mirrors to reflect the sun’s radiation and heat the Martian surface If a mirror this size were to be directed at Mars, it could raise the surface temperature of a small area by a few degrees. The idea would be to concentrate the mirrors on the polar caps to melt the ice and release the carbon dioxide that is believed to be trapped inside the ice. Over a period of many years, the rise in temperature would release greenhouse gases,
Another option for thickening the atmosphere of Mars, and, in turn, raising the temperature of the planet, would be to set up solar-powered, greenhouse-gas producing factories. Humans have had a lot of experience with this over the last century, as we have released tons of greenhouse gases into our own atmosphere, which some believe is raising the Earth’s temperature. The same heating effect could be reproduced on Mars by setting up hundreds of these factories.
Hurling large, icy asteroids containing ammonia at the red planet would produce tons of greenhouse gases and water. For this to be done, nuclear thermal rocket engines would have to be somehow attached to asteroids from the outer solar system. The rockets would move the asteroids at about 4 kilometers per second, for about 10 years, before the rockets would shut off and allow the 10-billion-ton asteroids to glide, unpowered, toward Mars. Energy released upon impact would be about 130 million megawatts of power. That’s enough energy to power Earth for a decade.
If it is possible to smash an asteroid of such enormous size into Mars, the energy of one impact would raise the temperature of the planet by 3 degrees Celsius. The sudden raise in temperature would melt about a trillion tons of water, which is enough water to form a lake, with a depth of one meter,
Terraforming Mars is actually possible at the moment, but it is a long-term project for future generations. We are beginning to see the need for thinking about moving off this planet with all the potential problems that are starting to rise. Global warming is most on people’s minds at the moment, but in years gone by it has been nuclear Armageddon. A large asteroid smashing into the Earth and making us extinct, like the dinosaurs is also another threat. Basically, if anything happens to Earth the human race dies.
We should start thinking about long-term goals and terraforming Mars. Future missions should be geared to this future. Who knows, your children’s children’s children’s children’s children’s children’s children , may one day walk on the surface of Mars.
