This is your portal to Mars.The Mars button takes you to Mars.
Start by building most of the 1x1 Mars modules in the ShipYard and sending them on Gamma 4 rockets from 1x1 Landing Pads or from the Gamma 4 Build/Launch Facility. Some of these 1x1 modules can then by recycled as complete modules back into your Mars inventory to be built into the more advanced 2x2 Mars buildings.
Start with the 2x2 Life Support Module as it can be placed anywhere.
Mars terraforming is complete at 1,000M Heat and Gas release. Touch on the "Supplies" box at the top right of the game to see your progress.
