re: BTW, this could be the root of a comet defense system
I'm waiting for some cosmic environmental group to protest NASA for causing the deliberate destruction of the comet. You know, all that native ice and rock being disturbed like that. They have rights too, ya know.
Watch, in 30 years we'll have people living on them to keep the space program from smacking them. Maybe this is what it will take to colonise space.
