The gravity method is a relatively cheap non-invasive non-destructive remote sensing method that has already been tested on the lunar surface It is also passive that is no energy need be put into the ground in order to acquire data thus the method is well suited to a populated setting such as Taos and a remote setting such as Mars

The Gravity Method

Methods of Determination There are two distinctly different methods of determining a specific gravity Sp G One uses heavy liquids that are mixed until a fragment of the unknown mineral exhibits neutral buoyancy in the solution not sinking nor rising

About Specific Gravity

Specific gravity sometimes referred to as Density is a useful diagnostic attribute when trying to determine the mineral species of an unknown mineral specimen But textbooks usually describe testing specific gravity using a laboratory balance scale that few of us have in our homes

Gravity Concentration Methods SpringerLink

Specific Gravity = Weight of Mineral in Air Weight of Mineral in Air - Weight of Mineral in Water So from this equation you need only first weigh the mineral in air which means the same as weighing it then suspend the mineral in water for the second weighing
