Just as science fiction author Ray Bradbury envisioned, NASA research strongly suggests the red planet was once green and covered by more oceans than found on Earth. So what happened to turn the fourth planet from the sun into a cold and barren crimson wasteland?
It was the sun that killed Mars. Violent solar winds stripped away the atmosphere over billions of years, leaving Mars naked and exposed to the harshness of space. Now NASA believes they can restore Mars to its former verdant glory — thus enabling the possibility of colonization — with the introduction of an artificial magnetic field. The magnetic field will allow the planet to develop an atmosphere, which in turn could help support life and liquid surface water in the future.
