This lecture covers the various electrical power sources used in spacecraft, including solar panels, batteries, fuel cells, and radioisotope thermoelectric generators. It explains the operating regimes of these power sources and the principles behind solar cells. The lecture also discusses the types and characteristics of batteries, such as NiCd and Li-ion, as well as the functioning of fuel cells in converting chemical energy into electricity. Additionally, it explores the use of radioisotope thermoelectric generators in spacecraft, highlighting their reliability and efficiency. The content is supported by examples from past space missions, such as the Shuttle program, Viking, Voyager, and Curiosity on Mars.
