What I usually do in situations like this, especially if I have a virtual machine system running, is to create one that looks like I want it -- then copy that VM when I need a new copy.  Make changes to the copy so that it looks as different from the original as you need.

Note this won't work if you are trying to iteratively create sharepoint instances (ie each instance is different due to something you learn while playing with the previous one).

How can I fully automate the creation and configuration of a SharePoint virtual machine?
In the Honor Harrington universe, ship-to-ship combat takes two forms: missiles and direct energy weapons.

Missiles come in two forms - bomb-pumped lasers and contact nukes.  Both use multi-megaton nuclear initiations to damage enemy ships.

While this sort of event on a planetary surface will obviously have lasting effects, what long-term effects could be expected in a vacuum environment, aside from the destructive force associated with the explosions themselves, and the resulting EMP?  Especially, would there be lingering (or spreading) radiation?
