Description: Section of multilayer thermal protection unfolded in the form of a fan to show the different layers on A4 sheet, signed by cosmonaut Anatoly Solovyev.
In order to shield the spacecraft's components from extreme temperature fluctuations in space, a multilayer vacuum-screen thermal insulation is applied to all exposed surfaces, except for the active components of sensors, antennas, windows, docking hardware, thruster nozzles, and radiator panels. Its Russian acronym is ЭВТИ, long for экранно-вакуумная теплоизоляция or Shield Vacuum Thermal Insulation. It consists of many layers of metalized film and fiberglass cloth.
