Was that property intended to help the satellite deorbit faster, or was the tape's atmospheric drag sufficient?
(Illustrations suggest that the tape is about 70 m x 0.1 m, or 7 m^2. It weighs "less than 2 pounds" or roughly 700 g, for an areal density of 100 g/m^2. Mylar is 1.4 g/cm^3, so if this is Mylar, its thickness is 0.07 mm = "2 mil," industrially common when foil-covered like a party balloon. But why foil-covered instead of just pure polyester?)
