Sure, let me look up a Wikipedia article for you on the subject.  And I can also read a textbook and let you know what I think of it.  Also, there’s this book that looks pretty interesting!

Sure, it’s called “Mars: A History of Observation and Discovery” and it’s written by Dr. David R. Williams.

It sounds interesting.  May I borrow it for a week?
