Detailed explanation-1: -Notes: NASA and the top federal nuclear research lab of the United States invited proposals for a fission surface power system. NASA is collaborating with the US Department of Energy’s Idaho National Laboratory to establish a sun-independent power source for missions to the moon.

Detailed explanation-2: -A fission surface power system works by splitting uranium atoms inside a reactor to generate heat that is then converted to electricity. This is the same physical process used by terrestrial reactors to generate power for use in homes, businesses, and industrial applications.

Detailed explanation-3: -Credit: NASA. A fission reactor works by splitting atoms and releasing energy in the form of heat, which is converted into electricity. The idea for using nuclear power in space dates back to the late 1950s, when they were considered for providing propulsion through Project Orion.

Detailed explanation-4: -Surface currents in the ocean are driven by global wind systems that are fueled by energy from the Sun.
