Was an inflatable 30 (or 41?) m diameter aluminum coated mylar balloon weighing 55 kg.

In 1975 the satellite broke up into dozens of pieces... numerous decayed but some remain in orbit. They are of special interest for scientist studying solar radiation pressure (SRP)... because on some orbits, the debris actually gain altitude!
