Who needs planet Earth when we’ve got Mars?? That’s what I’m saying. The Mars Society, a group of scientists who share a goal of colonizing Mars, believes that humans can colonize the red planet in little more than 1000 years, in stark competition with other scientist’s who say it would be 20,000-100,000 years. According to the society, Mars could be colonized in 3 steps, the first of which is occurring now, exploration. Though many human landings would need to take place, the following steps would involve sketchy actions, such as giant mirrors directing the sun to the planet in an attempt to warm it, freeing gasses and eventually creating a global warming type effect. One of the options would be to build several chemical plants on the surface, pumping out 1,000 tons of fluoromethane an hour, which would raise the temperature on the red planet by 50°F over 30 years. See the complete PopSci walkthrough for a complete walkthrough of scenarios for terraforming planet Mars.

I’m not sure if mars would ever be like planet earth. Since the outer core is dead. These could pose problems with radiation from the sun. But mars is diffenently more like earth than any other known planet.
