Electricity from Space: The 1970s DOE/NASA Solar Power Satellite

Of all the many spaceflight concepts NASA has studied with any degree of seriousness, probably the most enormous was the Solar Power Satellite (SPS) fleet. Czech-born physicist/engineer Peter Glaser outlined the concept in a brief article in the esteemed journal Science in November 1968, and was awarded a patent for his invention on Christmas

Reinventing the Solar Power Satellite

The selling price of electrical power varies with time. The economic viability of space solar power is maximum if the power can be sold at peak power rates, instead of baseline rate. Price and demand of electricity was examined from spot-market data from four example markets: New England, New York City, suburban New York, and California. The data was averaged to

SPACE-BASED SOLAR POWER: A NEAR-TERM

The concept of space-based solar power, also referred to as solar power satellites (SPS), has been evolving for decades. In 1968, Dr. Peter Glaser of Arthur D. Little, Inc. introduced the concept using when NASA and Raytheon used satellite components to send a wireless microwave electric signal across a mile-wide valley in Goldstone

What Powers a Spacecraft? | NASA Space Place – NASA

Solar power is energy from the Sun. Spacecraft that orbit Earth, called satellites, are close enough to the Sun that they can often use solar power. These spacecraft have solar panels which convert the Sun''s energy into electricity that powers the spacecraft. For example, NASA''s Juno spacecraft uses solar power all the way out at Jupiter
