[ExI] Asteroid on track for possible Mars hit

[John K Clark]

Idea for a science fiction novel: A huge nickel iron asteroid is heading for
Earth, it would take a 200,000 megaton bomb to divert it but no existing
rocket is nearly powerful enough to deliver such a huge payload to the
asteroid. The Earth seems doomed, then our hero remembers Project Orion
from the 1950's. 

It would certainly make a spectacular movie, the launch of an Orion type 
spacecraft would be amazing sight, it would make a Saturn 5 look like a 
bottle rocket.
