Density

Density is a measure of mass per unit volume. In space and astronautical engineering, density is an important parameter for designing spacecraft and their components. The density of materials used in spacecraft construction affects the overall weight of the spacecraft, which in turn affects the amount of fuel required to launch and maneuver the spacecraft. The density of propellants used in spacecraft propulsion systems affects the specific impulse, which is a measure of the efficiency of the propulsion system. The density of the atmosphere of a planet or moon affects the aerodynamic properties of spacecraft during entry, descent, and landing. The density of radiation in space affects the shielding requirements for spacecraft and their occupants.
