The notion that an asteroid impact could launch life-bearing debris to escape velocity is not new. I remember it being mentioned in one of Lester Del Rey's juvenile science fiction books -- possibly "Outpost of Jupiter", which according to Wikipedia was first published in 1963.

The difference is that this models a specific impact to see whether it would work. That's a long long way from conclusive, of course, but it's a useful addition.

I agree. I just find it interesting that the base idea has been around so long -- longer in fact than the "asteroid killed the dinosaurs" theory.
