I'm searching a little harder for books I haven't shared before. Here is a gem witten by the British astronomer Patrick Moore and illustrated by one of the best modern space artists David A. Hardy. Patrick Moore was the Carl Sagan of Britain when it came to astronomy and other spacy stuff.
This book was part of a schoolboy series of non-fiction books. Interesting and short books to capture the mind. Even though this one is only 71 pages it has a nice description of the history of space flight and a few drawings of the possible future in space from the British point of view.
