There is alot to be said about the way in which science and space is being co-opted into the military-industrial complex. This is huge topic worthy of much research - especially the vast amounts of money going into the weaponisation of space, some of this filtered through scientific agencies and covert funding.
Some initial noteworthy links here:
1. A Google Video from Noam Chomsky speaking at MIT on The Militarization of Science and Space
2. A short yet informative article titled 'Master of Space' by Karl Grossman
3. A site with some good resources called 'Global Network Against Weapons & Nuclear Power in Space'
And I'm sure there's more to come...
