Re: Satellites in Space

The nuclear pulse Orion (not the current Apollo style capsule of the same name) worked better in Earth's atmosphere due to there being a shock wave to harness.

An Orion pulse unit would be good against an asteroid in that, unlike a gravity tractor that means you have a long Rosetta style matching trajectory before you can even begin a mission.

The pulse unit would be about the same size and shape of the copper impactor disk used by the Deep Impact mission--which only needed a fly-by trajectory.
