Basically in this operation not only were highly complex technologies used to control and create artificial gravity, but also to form and develop suitable solutions to melt the ice plains of the southern hemisphere of Mars, and to create other essential models to support the artificial environment, so that the planet would not regress to its original dead state again in the future.
Not forgetting the great shield that was created around it so as to protect Mars' atmosphere. As the biggest problem with Mars isn't just that it's cold or that the environment is unstable. Those were actually the easiest things to solve. The real problem was the global magnetic field.
