7. 7 Section 8.1 Solar Power Systems in Space Solar Power Plant in Space Technology Challenges Low-Cost, Environmentally-Friendly Launch Vehicles - Cheaper, cleaner launch vehicles are needed. Large Scale In-Orbit Construction and Operations - To gather massive quantities of energy, solar power satellites must be large. Power Transmission - Small effort is needed to assess how to best transmit power from satellites to the Earth’s surface High Development Cost - Space solar power development costs will be very large. Potential Health and Safety Impacts – Flora and Fauna Life Cycle Costs – 50 years vs.??? Location Competition – GEO population
