College Park, United States— After devastating the French Riviera in 2013, destroying Dhaka in 2015 and saving Tokyo in 2017, an international asteroid impact simulation ended Friday with its latest disaster—New York in ruins.
Despite a simulated eight years of preparation, scientists and engineers tried but failed to deflect the killer asteroid.
The exercise has become a regular event among the international community of “planetary defense” experts.
The latest edition began Monday near Washington, with the following alert: an asteroid roughly 100 to 300 meters (330 to 1,000 feet) in diameter had been spotted and according to rough calculations had a one percent chance of hitting the Earth on April 29, 2027.
Each day during the conference, some 200 astronomers, engineers, and emergency response specialists received new information, made decisions and awaited further updates from the organizers of the game, designed by a NASA aerospace engineer.
As fictional months ticked by in the simulation, the probability of the giant space rock crashing into Earth rose to 10 percent—and then to 100 percent.
NASA launched a probe in 2021 to examine the threat up close. In December that year, astronomers confirmed it was headed straight to the Denver area and that the western US city would be destroyed.
The major space powers of the United States, Europe, Russia, China, and Japan decided to build six “kinetic impactors”— probes meant to hit the asteroid to change its trajectory.
It took time to build the impactors and wait for the right launch window. The impacts were set for August 2024.
Three impactors managed to hit the asteroid. The main body was deflected, but a smaller fragment broke off and continued on a deadly path, this time towards the eastern US.
Washington considered sending a nuclear bomb to deflect the 60-meter rock—repeating a successful strategy that saved Tokyo last year—but it was crippled by political disagreements.
All that remained was to prepare for impact.
With six months to go, experts could only predict that the asteroid was headed to the New York area. With two months to go, it is confirmed the city will be destroyed.
It will destroy everything within a 15-kilometer “unsurvivable” radius, scientists said. Manhattan will be completely razed. Windows as far as 45 kilometers away will shatter and damage will extend as far out as 68 kilometers from the epicenter.
The fictional killer asteroid is, of course, “highly unlikely,” Paul Chodas, the NASA engineer who is the game’s designer, told AFP. “But we wanted the issues to be exposed and discussed.”
