Radio Telescopes & Space Pollution

Nearly all the pollutants in our everyday environment can be found easily — albeit less problematically — when one leaves our planet’s surface.

And the atmospheres of Mars and Venus are mostly carbon dioxide, which at least in our atmosphere, where it is only a trace gas, the Supreme Court says it can nonetheless be mitigated under the Clean Air Act.
