Mars could be warmed into a habitable world using giant mirrors and artificial greenhouse membranes.

Terraforming is often dismissed as a fantasy for the distant future. This research roadmap identifies three specific engineering pathways to raise the temperature on the Red Planet. One method involves using solid-state membranes that act like a global greenhouse to trap heat. Another uses massive reflectors in orbit to beam sunlight down to the frozen surface. These aren't just ideas, but structured technical plans that outline the exact energy and materials required. It moves the conversation from if we can warm Mars to how we will build the machines to do it.
