Applying Ultra-Dark Vantablack to Satellites May Address Light Pollution Issues

A breakthrough in satellite technology could alleviate the growing issue of satellite light pollution affecting astronomical research, particularly from megaconstellations like SpaceX’s Starlink. The new paint, Vantablack 310, developed by Surrey NanoSystems in collaboration with the University of Surrey, reduces light reflection from satellites to just 2%, compared to about 5% from existing options. This advance is crucial, as the upcoming $1.9 billion Vera Rubin Observatory anticipates that satellite streaks may degrade up to 40% of its captured images. Unlike previous coatings that were delicate and complicated to apply, Vantablack 310 is durable, easy to handle, and capable of withstanding the harsh conditions of space. Initial tests will be conducted on the student satellite Jovian 1, with hopes that widespread adoption will inspire policy changes to protect dark skies for future astronomical research.
