“I think that we would have tried very hard to launch an interceptor mission,” Dr. Joseph A. Nuth, a senior asteroid scientist at NASA’s Goddard Space Flight Center, told The Daily Caller News Foundation.“Given the short time to impact this would most likely have been a mission that would target the asteroid on close approach,” Nuth said. “My guess is that the mission would carry the largest nuclear device possible and would try to both disrupt the body and slow its approach.”
NASA’s nightmare scenarios is an asteroid on an impact course with Earth. Nuth isn’t sure NASA could get a mission together in time to stop it. It could take five years just to build a spacecraft capable of the intercept.“Given the short warning time, the mission might not work,” Nuth said. ” No design is available for such a mission so everything would be done ‘on the fly’ with little review or testing and probably no backup options. ‘Hail Mary passes’ do occasionally work however, so this attempt might work as well.”. . .
In recent war games, NASA and other federal agencies were unable to deflect a simulated asteroid on course to hit Earth with four years of warning.
The “city-killer” asteroid ended up land off the Southern California coast. Federal Emergency Management Agency (FEMA) personnel were forced to coordinate a simulated mass evacuation of the Los Angeles area to mitigate the damages of a potential tsunami.
