I bet this is wishful thinking and it ignores that all satellites block the view on space!
Like putting lipstick on a pig. Each satellite still blocks earthbound astronomical observatories. This measure only seems to take care of the light streaks emanating from passing satellites.
According to Google Search:
- "As of May 2025, there are approximately 11,700 active satellites orbiting Earth.". These are only active satellites. There are probably hundreds or even thousands of inactive/old satellites in orbit and tons of satellite debris.
- "In the next five years, it is expected that tens of thousands of new satellites will be launched into Earth orbit, with estimates ranging from 58,000 to 70,000. This surge is largely driven by the deployment of large satellite constellations for internet access, like SpaceX's Starlink."
We may have to put more astronomical observatories in earth orbit too!
"“A new type of super-black, highly resistant satellite paint promises an affordable fix to the satellite light pollution problem that has marred astronomical research since the recent advent of low-Earth-orbit megaconstellations…
The new coating is based on a proprietary blend of carbon black, a soot-like form of carbon, mixed with special binders that make the paint resistant against the harsh conditions in near-Earth space. In tests, the new coating outperformed other similar paints currently on the market not just in terms of its light absorption ability but also durability in space, Clifford said…"
Coating satellites with super-dark Vantablack paint could help fight light pollution crisis "Light streaks caused by passing satellites mar images taken by the world's most expensive telescopes. The problem is set to get worse."
