Terraforming of Mars

Terraforming Mars is a process of changing the environment of Mars to make it more like Earth so that people can live on Mars. This process would include changing the atmosphere of Mars, making it thicker and more like Earth's atmosphere so it can hold onto heat, warming up the planet, and adding more water to the surface so plants can grow. Scientists are trying to develop ways to do all of these things, but it is a very difficult task and we don't know when it will be possible.
