David Grinspoon Quote
His suggestion is that we should adopt best practices so we don’t turn on our radar systems when they are pointed toward nearby stars, or intersecting the plane of the Milky Way galaxy, where there are, unavoidably, many stars in the background. It ought to be mentioned here that planetary radar is one of our main tools for learning about the properties of asteroids that may someday threaten life on Earth, and how we might mitigate against them. So any serious curtailment of this technology to avoid one suspected existential risk might cause increased vulnerability to a known one. Gertz’s radical anti-METI
