Insulation
Material used to reduce the transfer of heat or electricity, protecting sensitive components from extreme temperatures or electrical currents.
TECHNICAL DEFINITION
Materials or systems designed to impede the transfer of thermal energy (thermal insulation) or electrical current (electrical insulation), crucial in aerospace for protecting sensitive electronics, maintaining cryogenic propellant temperatures, and shielding structures from extreme environmental conditions.
BACKGROUND
In spacecraft design, the function of the thermal control system (TCS) is to keep all the spacecraft's component systems within acceptable temperature ranges during all mission phases. It must cope with the external environment, which can vary in a wide range as the spacecraft is exposed to the extreme coldness found in the shadows of deep space or to the intense heat found in the unfiltered direct sunlight of outer space. A TCS must also moderate the internal heat generated by the operation of the spacecraft it serves.

USAGE NOTE
Effective insulation is vital for cryogenic propellant tanks to prevent boil-off and maintain fuel temperature.
