Geological Resources

Geologic Resources

• Mineral Resources: metals, fertilizers, minerals, petroleum, construction

Geologic Resources

• Mineral Resources: metals, fertilizers, minerals, petroleum, construction

• Water resources: Lakes, Rivers, Springs, Groundwater

Geologic Resources

• Mineral Resources: e.g., Metals, fertilizers, minerals, petroleum, construction

• Water resources: e.g., Lakes, Rivers, Springs, Groundwater

• Energy: e.g., Oil, natural gas, coal,

nuclear, silicon, hydroelectric (dams), hydrothermal (Earth’s heat)

• The Geologist’s Job– Locating and

Characterizing quantity and quality of geologic resources

– Extracting geologic resources efficiently

– Assessing environmental effects of extraction and use

Engineers use knowledge of geology to design, protect and correct structures

Steve Squyres says that, even though the MER's work will have just begun, he'll feel like celebrating the moment he's got "six wheels in the dirt."

Guided by MER specialists back on Earth, each rover will travel dozens of yards a day while investigating sites of interest.
