A space agency is planning a long-duration crewed mission to establish a permanent scientific outpost on Mars. The agency must choose between a system reliant primarily on nuclear energy (such as small fission reactors or radioisotope systems) and one reliant on solar photovoltaic arrays with regenerative fuel cell battery storage.
Discuss the advantages and disadvantages of using nuclear energy systems compared to solar energy systems to power this Martian outpost. Your discussion should address operational reliability, energy density, and radiation safety.
