I say cheapish since I am attaining this information to do more research about Space Exploration and I need around 20 sources; obviously some of my sources come from magazines, various documentaries and websites but it'd be more academic of me to get some detailed research. I am doing a dissertation for my extended project in School and the question that I chose to argue for and against was:
"Can human space exploration be justified?"
I'm obviously a keen Physicist in my studies and I really like the idea of space exploration so I thought why not, but obviously I do need some decent information to source my research from so I was wondering if anyone could recommend some journals/books related to this? Obviously I have to take into account many issues related to it such as global recession, political views, economic views, scientific views, ethical issues! etc. you catch my drift...
If they can be accessed online even better, but I don't mind forking out some cash in order to attain some decent research!
Has yours come through yet?
