While everyone is pretty excited about NASA’s ability to nudge a distant asteroid via its Double Asteroid Redirection Test (DART) mission, there is more than one way to look at this event. While many see this as a new tool to protect the Earth from approaching peril, Carl Sagan saw this it more as a double-edged sword.
In his 1994 book Pale Blue Dot: A Vision of the Human Future in Space, Dr. Sagan wrote:
Can we humans be trusted with civilization-threatening technologies? If the chance is almost one in a thousand that much of the human population will be killed by an impact in the next century, isn’t it more likely that asteroid deflection technology will get into the wrong hands in another century—some misanthropic sociopath like a Hitler or a Stalin eager to kill everybody, a megalomaniac lusting after “greatness” and “glory,” a victim of ethnic violence bent on revenge, someone in the grip of unusually severe testosterone poisoning, some religious fanatic hastening the Day of Judgment, or just technicians incompetent or insufficiently vigilant in handling the controls and safeguards? Such people exist. The risks seem far worse than the benefits, the cure worse than the disease.
You might also remember the stealth asteroids directed at Earth by terrorists in the fifth season of the television series The Expanse. Yes, it is science fiction, but so wasn’t the idea of landing humans on the Moon until it was a fact.
As we watch the Middle East burn again, it is not hard to imagine a battle involving sociopaths, ethnic violence victims, leaders with severe testosterone poisoning, religious fanatics, or even incompetent individuals without guardrails making more of a mess of the Earth and its surroundings.
It’s just a thought.
