What Powers a Spacecraft?
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
Solar Energy For Space Exploration: The Potential And Challenges
Solar energy is a valuable source of power for space missions, but there are several challenges that need to be overcome to make it a viable option for extended space exploration. One
Space-Based Solar Power: Feasibility, Economics, and Engineering in
The concept of harvesting energy directly from the sun in orbit and beaming it to Earth has transitioned from theoretical physics to active engineering validation. As of 2025, Space-Based

OverviewHistoryUsesImplementationIonizing radiation issues and mitigationTypes of solar cells typically usedSpacecraft that have used solar powerFuture uses
Spacecraft operating in the inner Solar System usually rely on the use of power electronics-managed photovoltaic solar panels to derive electricity from sunlight. Outside the orbit of Jupiter, solar radiation is too weak to produce sufficient power within current solar technology and spacecraft mass limitations, so radioisotope thermoelectric generators (RTGs) are instead used as a power source.
Solar Panels and Space-Based Power Plants
However, most spacecraft in low Earth orbit or operating within the inner Solar System are powered by converting the Sun''s thermal energy into electricity. This process involves the use of
