During our Phase 1 NIAC study we discovered a novel coating we call “Solar White” that, when used in deep space, is predicted to reflect more than 99.9% of the sun’s energy. We have shown analytically that a sphere covered with a 10 mm thick coating of Solar White and located far from the Earth and at 1 Astronomical Unit from the Sun can achieve a steady state temperature below 50 K, the freezing point of oxygen.
