Space and Astronomy

This book is the best

This book is the most insightful and educational text I personally have ever read about space and astronomy. As a rocket scientist myself, I must commend the authors of this fine non-fictional piece and their extensive knowledge on space and rocket ships which goes above and beyond anything I ever knew. Thank you for writing such a masterpiece.
