Mars is the closest planet to Earth, so scientists call it the most promising planet to inherit human civilization, but the environment of Mars is far worse than the Earth, so to settle Mars, the first thing we need to make Mars a habitable environment, but it is easy to say, may be difficult to do as heaven! After all, to transform a planet, this is a very grand plan!
However, Musk, the richest man in the world, once proposed using nuclear weapons to transform Mars, but was rejected by scientists, not only harm more than good, and the probability of success is very low! Of course, Musk's plan is not completely wrong. At least the idea of putting greenhouse gases into the atmosphere is right, but the execution method is all wrong.
To carry out Musk's approach, the first step should be to stop the loss of greenhouse gases from solar storms and energetic particles from the sun. When these phenomena interact with the Martian atmosphere, they can cause molecules like CO2 and H2O to be ejected into space to stop this from happening. NASA scientist Jim Green has come up with an idea to stop the sun's harmful effects on the Martian atmosphere.
Green proposed that humans could launch a series of spacecraft to create a magnetic shield between Mars and the sun. The shield would act as a kind of transparent umbrella, blocking harmful radiation while allowing certain wavelengths of light to reach Mars 39bet-xsmb-xổ số tây ninh-xổ số binh phước-xổ số binh dương-xổ số đồng nai. The shield itself does not block all of the Sun's light, but protects Mars in a way similar to the way Earth's magnetic field protects our planet. This would prevent molecules in the Martian atmosphere from being ejected deep into space and allow them to accumulate over time by reducing the amount of greenhouse gases. As a result, Mars' atmosphere would thicken and cause the planet to warm. This would help Mars begin the topographic process without any human intervention, but it would be an extremely slow process, and while it might not produce a habitable Mars, it would certainly be a step in the right direction that humans need to consider if we are to live on this planet.
The trickiest part of the whole process is correctly placed shield, that needs to be accurate calculation, to ensure that the magnetic shielding follows the orbit of Mars, and make it protected. If magnetic shielding off its orbit and even a few millimeters, so Mars will no longer be in the shadow, the sun's radiation will again from the peel particles in the atmosphere. Now, humans have the technology to start planning magnetic shielding. But before we can launch a successful mission, we need to make calculations and contingency plans, because the shield can't do it alone. We still need to find a way to inject more greenhouse gases into the Martian atmosphere.
Although Mars doesn't have enough carbon dioxide on its surface rocks, the planet may have enough depth inside. That means a nuclear explosion on the Martian surface would release small amounts of greenhouse gases into the atmosphere, but in order to terraform Mars successfully, we'd need to go much deeper. Minerals located further underground may contain more carbon dioxide than the surface, and so may be where we find the greenhouse gases we need to make Mars habitable for humans. The problem with this plan is that it covers almost the entire surface of Mars. Even if we excavate parts of Mars, it would be a massive drilling operation, and we don't have the technology to do that right now.
It has been estimated that by digging up the Martian surface, we might be able to release enough greenhouse gases into the atmosphere to raise Earth's temperature. However, we don't know if buried Martian rocks and minerals contain enough carbon dioxide to have the desired effect. Another problem is that it would take a lot of energy to evaporate the amount of rocks and minerals needed for terraforming, and even if we detonated all the nuclear weapons we currently have on Mars, it wouldn't be enough. Scientists believe the only way to generate enough constant energy is to use a fusion power source similar to the sun. However, we do not yet have the technology to create a fusion reactor. This means that if humans can develop a machine capable of producing fusion reactions and can place a magnetic field on the surface of Mars, then theoretically deforming the surface of Mars!
But nuclear weapons are nuclear weapons, and they have irreversible consequences. So are there other ways to terraform Mars so that humans can one day live on it? There is!
Another way to change the composition of Mars's atmosphere and turn it into a habitable planet is to bombard it with asteroids. None of the world's nuclear weapons are as powerful as slamming a giant asteroid into the Red Planet, which has another benefit besides acting as a giant bomb. Some scientists believe that by trapping a large asteroid filled with ice and ammonia, we could release the energy needed for water and carbon dioxide into the atmosphere, while adding more greenhouse gases to the planet. Ice within the asteroid could have evaporated into the Martian atmosphere after impact, causing ammonia to evaporate from the Martian surface and act as its own greenhouse gas. The energy released at impact converted the Martian surface into usable greenhouse gases, as well as water and ammonia contained within the asteroid.
In this way, the process of topography formation could be greatly accelerated. But there are bound to be problems with the plan, such as how to collect asteroids from the asteroid belt. Fortunately, with our current technology, we can land a spacecraft on the surface of an asteroid and use its thrusters to push the asteroid in one direction, or even push the space rock directly toward Mars. But the hard part is finding asteroids with the right composition that, if they're near Mars, can be used to terraform Mars. So we need to have plenty of time to do observation missions up front, to determine the composition of the candidate planets, and then figure out how to move a 10-billion-tonne asteroid.
However, once the asteroid is set on the right trajectory, its momentum will carry the space rock directly through the Martian atmosphere and slam it into the planet, which will generate about 130 million megawatts of power and, according to calculations, raise the temperature of Mars by about 35 degrees. This temperature change could cause some of Mars' ice caps to melt, meaning the asteroid would not need to be aimed directly at the poles, causing Martian water to evaporate into the atmosphere. Unfortunately, a single 10-billion-billion-tonne asteroid is not enough to form land on the Martian surface.
Need more asteroid collision, that is to say, Mars each collision will add more greenhouse gases into the atmosphere, but in order to achieve sufficient to raise the temperature to maintain the level of life, every time an asteroid need dozens of collision, the planets will experience a warming period, and then cooling for a period of time, until all is ejected into the atmosphere will return to the surface of Mars surface particles, This means using the asteroid to terraform Mars may achieve, but in order to realize the Mars terraforming may need a few centuries, perhaps the easiest way is like we have done to his own planet, set up factories, fuel combustion, carbon dioxide and other greenhouse gases released into the air, this is joking, of course.
