Hi, Ed.
While it is true that two baskets beat one, they cancel each other out if your going to place both baskets in the middle of a freeway.
Also, and heavy Martian impactor would be far more devastating to human life (in the current format), since the resulting marsquakes would likely fracture walls of habitats. At the moment, I don’t know of anybody who likes a vacuum -- and I believe the feeling to be mutual.
The Galactic Plane:
Would it not be feasible for the disk of the galaxy to be more churned today, as well as more cleared of garbage and debris, than just a few billion years ago? A lot has been orbiting through it over the years -- and along the same path the Solar system follows. This would imply less traffic on that freeway that’s holding our egg baskets.
Also, going to Mars and establishing a permanent presence, both there and on the Moon, will greatly assist in the NEO/NMO watch, and this experience will enable us to handle hazardous situations in space a lot better, with greater resources, and with many more hands and minds working on the operation.
We’re not going to learn just sitting here,
Dan
