Disclosed is a spacecraft including a body having a face, a radiator carried by the face, and a thermal insulation device capable of thermally insulating the body from the space environment. The thermal insulation device includes a flexible insulating sheet that is movable between an unfolded position in which the flexible sheet covers a coverable area of the radiator, and a position folded on itself in which the coverable area of the radiator is exposed to the space environment. The flexible sheet includes multiple pleats which extend perpendicularly to the direction of movement of the flexible sheet, the pleats being folded against one another when the flexible sheet is in the folded position, the pleats being spaced apart from one another when the flexible sheet is in an unfolded position.
