SituationNASA's latest Mars rover, Curiosity, is currently exploring carpets, as part of a mission to determine whether life could exist there. If we want to colonize Mars – and some scientists say we must – it's likely we'll start with terraforming. Terraforming, or planetary engineering, is the process of modifying a planet's climate to make it more hospitable to human life and exploration. Of all the bodies in the solar system, Mars is by far the best candidate. Why Mars? Mars' unique history makes it the most attractive planet to terraform. As far as we know, Mars is one of the only planets that is much more like Earth than any other planet. If we were to choose any other planet in the world, near-magical technology would be required to perform tasks such as accelerating the planet's rotation. Or even create an atmosphere. Mars was chosen as the planet best suited for terraforming due to the similarities it shares with Earth. Although they are similar, they are simply not suitable for human life. For example, the planet always receives sunlight unlike some other planets. The time it takes to rotate is only a matter of minutes difference from Earth. The temperature is not as cold as on other planets, but it would also have to be adjusted so that life could take place on Mars. There are other planets that could be included and possible to live on. Venus, Europa (one of Jupiter's moons), Titan (one of Saturn's moons). The problem with Venus is that it is much too close to the sun and the two moons are too far apart that the planet is simply too cold. This is why Mars was chosen as the only planet in our solar system (excluding Earth) that would be possible to support humanity...... middle of paper ...... mathematical equation from Marie where you can answer it in about 2 seconds. Life on Mars is not easy. It will take time. First, you need to produce the necessary gases that will warm the planet, change the ozone layer, and make the air breathable. It's made with my perfluorocarbons. which could take up to 2,000 years. For the algae to have an effect it could take perhaps 7 years. Additionally, the travel time can take up to 8 months. This leaves us with a calendar of 2007 years, 8 months and one day if we start tomorrow. Conclusion Traveling to Mars would be one of the most difficult things an astronaut would face. But terraforming Mars could be even more difficult. In order to terraform Mars, five challenges had to be overcome and the solutions have been noted above. But the ultimate solution would be to artificially manufacture perfluorocarbons.
