Terraforming Mars: Challenges and Possibilities

What are the basic requirements for humans to survive on Mars without extensive equipment?

• Growing food, building shelters, and finding water

• Navigating the terrain, avoiding radiation, and finding food

• Avoiding dust storms, finding oxygen, and staying warm

• Breathing, staying conscious, and not freezing

What evidence suggests that Mars once had a more hospitable climate?

• Plumes of sublimating dry ice

• Evidence of liquid water on the surface

• Presence of towering volcanoes

• Swirling dust storms

What is a major challenge in creating a breathable atmosphere on Mars?
