In this survey, we introduce effective means for extracting salt in the partially terraformed future environment. The “salt” is an essential item in order to secure health condition for human, accordingly, it is an urgent issue how we can obtain salt if we live on a planet or in an aircraft in space. When living on the earth, it is basically possible to obtain salt by heating or drying seawater. Heating in closed space means not only that we have to consume oxygen and fuels but also we may have the risk of fire in closure environment. However, the non-artificial way of drying seawater requires large space and has the risk of turbidity of regolith. Additionally, in the first place, it is harder under microgravity because water forms a sphere. Here we would like to propose that we utilize mangrove as the third way to obtain salt. It's the way to grind their leaves because they store higher concentrations of salt from seawater.
