Space Solar Power
Space Solar Power (SSP) comprises a constellation of satellites in space, collecting solar power and beaming it securely to receivers either on the Earth or in space. Its main attribute is the ability to deliver clean, baseload energy to

Is NASA too down on space-based solar power?
NASA studied the idea in the 1970s but found that with space shuttle launches and astronaut assembly it was prohibitively expensive. Advances in automated assembly and sharp drops in the costs of solar panels and rocket

Is space-based solar energy cheaper than ground-based energy?
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.
What is space-based solar power?
Space-based solar power has many charms. For one, there are no clouds in space, and, in the right location, no night. In geostationary orbit, arrays of solar panels can track the Sun and gather energy 24/7, sending it to Earth in microwave beams gentle enough to avoid frying birds and airplanes.
Is space-based solar power a viable alternative energy source?
Space-Based Solar Power appears to have strong benefits as a complementary energy source alongside terrestrial renewable energies in our path towards decarbonisation.
Can NASA engage with global interest in space-based solar power (SBSP)?
This study evaluates the potential benefits, challenges, and options for NASA to engage with growing global interest in space-based solar power (SBSP).
Can space-based solar power help Europe achieve net zero?
The aim of the studies were to provide ESA and its Member States with the necessary technical and programmatic information regarding the feasibility and potential of Space-Based Solar Power to provide environmentally sustainable, affordable and clean energy for Europe to meet its growing future energy needs and 2050 Net Zero goal.
How much power does a Solar System deliver?
Taking the scaling factor for each system and inefficiencies into account, and incorporating each system’s capacity factor, results in final power delivery of approximately 2 GW (or about 13% of the incident solar energy). We further break each system into five ConOps phases to evaluate costs by each phase of the full operational lifecycle.
