Nuclear asteroid deflection simulated in government laboratory in wake of Armageddon-style event
As if last year’s fabulous Dual Asteroid Redirection Test firing a satellite bullet into an asteroid wasn’t enough, now researchers are doing detailed simulation of the nuclear deflection scenario envisioned in 1998 space disaster film Armageddon.
At Lawrence Livermore National Lab, a team led by Mary Burkey (above) presented a paper that moves the ball forward on what is in reality a fairly active area of research.
The problem is that a nuclear deflection would need to be done in a very precise way or else it could lead (as it did in Armageddon) to chunks of the asteroid hitting Earth anyway.
In particular, understanding whether or not an attempted deflection mission will break apart an asteroid has been a long-standing question in the planetary defense community.
Every detailed, high-fidelity simulation and every broad sensitivity sweep brings the field closer to understanding how effective nuclear mitigation would be.
