Question

What is space exploration?

Answer 1

Since this is not my area of expertise, I searched Google under the key words "space exploration" to get these possible sources:

http://en.wikipedia.org/wiki/Space_exploration
http://adc.gsfc.nasa.gov/adc/education/space_ex/index.html
http://www.nasa.gov/
http://books.google.com/books?q=%22space+exploration%22&source=bll&sa=X&oi=book_group&resnum=19&ct=title&cad=bottom-3results

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps. Thanks for asking.
