New material aims to reduce satellite reflections
A group of astrophysicists is investigating ways to address the growing problem of night‑sky brightening caused by expanding satellite constellations. Their focus is an ultra‑black coating designed to absorb the majority of sunlight reflected by satellites.
How it works and its potential impact
The coating can absorb nearly all incident light, cutting the visual signature of satellites dramatically. Laboratory tests indicate a reduction of reflected light by up to 95 %, which would significantly alleviate interference with astronomical observations.
Development status and implementation prospects
The prototype is currently undergoing validation. Researchers are evaluating methods to apply the coating to both existing and future satellite fleets without compromising thermal management or operational performance.
Future outlook
If proven effective, the technology could be adopted by space agencies and commercial operators to minimize satellite glare, preserving the night sky for scientific research and public enjoyment.
