Human Expedition To Mars Can Be Powered By Using Solar Energy, Say US Researchers

Image
As humanity plans an expedition to the Martian surface, one would speculate that nuclear power would be the best option for faraway crewed missions. Researchers at the University of California (UC), Berkeley , have now shown that a crewed mission to Mars could be powered by solar energy. Image Credits: Pixabay The current study is unique because the researchers compared the distinct ways of generating power and evaluated the requirements of a nuclear-powered system against various photovoltaic devices and photoelectrochemical devices. Photovoltaic devices are those devices that convert sunlight directly into electricity, whereas photoelectrochemical devices convert abundant solar energy into stored electrical energy. Comparing The Power Generating Options A small nuclear fission device is location-agnostic (independent of nuclear outpost location establishment), while the efficiency of solar power devices relies on the intensity of sunlight, surface temperature and other factors that
