I have been looking for this for a while

Rendezvous with Rama by Arthur C. Clarke, maybe?

Note to self: not it.

[Oottah]

This is Marc Stiegler's EarthWeb I think Earthweb

The people trying to disable the defenses are advised by teams on Earth that are paid based on how accurate their predictions of enemy action are, right?

Great. You can move this thread to the "Solved" folder - there should be a "edit" field right by the title of the thread which lets you do that.
