The report evaluates the potential benefits, challenges, and options for NASA engagement with growing global interest in space-based solar power (SBSP). SBSP entails collecting solar energy in space, transmitting it to Earth, converting it to electricity, and delivering it to the grid. Proponents claim SBSP could provide carbon-free renewable energy at
On earth, solar power is greatly reduced by night, cloud cover, atmosphere and seasonality. Some 30 percent of all incoming solar radiation never makes it to ground level. In space the sun is always shining, the tilt of the Earth doesn''t prevent the collection of power and there''s no atmosphere to reduce the intensity of the sun''s rays.
It could be a trillion-dollar industry," says former NASA researcher John Mankins, who evaluated space solar power for the agency a decade ago. Major investments are likely far in the future, and myriad
The first patent for a microwave-based method of transmitting power from orbit was granted in 1973 to NASA engineer Peter Glaser, who also outlined the engineering concepts for his proposal in an influential 1968 Science article titled "Power from the Sun: Its Future." SSPD-1 is the first space-based solar power demonstrator to reach
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 NASA. has a long history of SPS research dating back to 1975, when NASA and Raytheon used satellite components to
The CASSIOPeiA Solar Power Satellite would have to be built in orbit by robots. (Image credit: International Electric Company) It would provide 13 times more energy than an identical ground-based
Countries around the world are investing in space-based solar power research and development, and international organizations are focused on reducing carbon emissions to net-zero by 2050. NASA is considering how best to support space-based solar power development. "Space-Based Solar Power," a new report from the NASA''s Office of Technology,
"Space-Based Solar Power," a new report from the NASA''s Office of Technology, Policy, and Strategy (OTPS) aims to provide NASA with the information it needs to determine how it can support the

"This successful test is a really important milestone on the way to making space-based solar power a reality," Paul NASA''s 15-year-old NEOWISE asteroid hunter meets fiery doom by burning up in
A NASA report from early 2024 estimates that a space-based solar array with a capacity of around two gigawatts - comparable to the Diablo Canyon Nuclear Power Plant in California - would span 10 to 20 square kilometers and weigh up to 10,000 tons. For perspective, this is more than the combined weight of 4,000 SpaceX Starlink satellites and
So space-based solar shouldn''t be seen as a competitor to Earth-bound solar farms, says a 2022 report on the technology by the European Space Agency. The world needs as much renewable energy as
WASHINGTON — Advocates of space-based solar power are criticizing a NASA report that offered a skeptical assessment of that technology''s ability to provide low-cost green energy.
The idea is to use huge solar arrays parked in space to collect and beam solar energy down to remote ground stations on Earth via focused microwaves. Space solar power stations could beam collected energy to anywhere they can see; the transmitted energy can pass through clouds.
Oxfordshire-based Space Solar estimates that a solar power-generating satellite would produce energy at a cost of just $34 per megawatt hour by 2040 to break even over its lifetime, against $43
A 1980 review by NASA concluded that the first gigawatt of space-based solar power (enough energy to power 100 million LED bulbs) would cost more than $20 billion ($100 billion today).
Space-based solar power offers tantalizing possibilities for sustainable energy—in the future, orbital collection systems could harvest energy in space, and beam it wirelessly back to Earth. These systems could serve
When NASA adopted rosier assumptions—$500 per kilogram launch costs, electric space tugs to boost orbits, and cheaper hardware—it found that space-based solar power was not only just as cheap as ground-based renewable energy, but also just as green, in terms of its life-cycle greenhouse gas emissions.
A step by step diagram on space based solar power. Space-based solar power (SBSP or SSP) is the concept of collecting solar power in outer space with solar power satellites (SPS) and distributing it to Earth.
A NASA illustration of two kinds of space-based solar power systems it studied, comparing their cost and environmental impact with alternative energy sources. (credit: NASA) Mankins thinks the issue is a lack of interest at NASA about space solar power. "NASA really doesn''t want to work on this in general. NASA has its major missions.
A new NASA report found that space-based solar power — a futuristic concept pulled from the pages of science fiction — is likely too expensive to work, but it also lays out exactly what would need to change to make it a viable source of clean energy in the future.. The challenge: Solar power is a revolutionary weapon in the battle against climate change.
Credit: ESA WASHINGTON — NASA is starting a study to reexamine the viability of space-based solar power, a long-touted solution to providing power from space that may be getting new interest thanks to technological advances and pushes for clean energy.
Power generation on SmallSats is a necessity typically governed by a common solar power architecture (solar cells +solar panels + solar arrays). As the SmallSat industry drives the need for lower cost and increased production rates of space solar arrays, the photovoltaics industry is shifting to meet the demands.
