“When explorers first set out to discover new lands, they couldn’t take everything they needed with them. They packed what they could and then lived off the land once they arrived, using trees for building materials, making bricks out of clay, securing water and food from the earth. It will be no different when humans explore deeper into our solar system, using in-situ resource utilization, or ISRU – where an abundance of resources, such as water, reside in greater amounts in space than here on our home planet. The water is frozen or chemically bound to the regolith, and excavation is a crucial step in acquiring the water necessary to survive and travel in space.”
