Spaceliners...
Hi Spacers
As I said this doesn't reasonably apply to current space-probes. Nothing qouls be left after hitting the atmosphere at hyperbolic speeds. I was talking about manned DSVs massing in the 100 - 1000 ton range... or higher.
And by the time gas-core reactors and/or fusion drives are happening in space then the "no nukes in space" policy will seem quaint.
