    The sunshield component attaches to the main spacecraft, and its booms expand outward spreading out the heat shield and separating the layers. [24] During launch the shield is folded up; later, when it is in space, it is carefully unfurled. [24] When the sunshield is fully spread open, it is 14.6 meters (48 ft) wide by 21.1 meters (69 ft) long ...

    This heat shield was composed of phenolic formaldehyde resin. During reentry, this material charred and melted away, absorbing and carrying away the intense heat in the process. The heat shield has several outer coverings: a pore seal, a moisture barrier (a white reflective coating), and a silver Mylar thermal coating that looks like aluminum foil.
