I would not say that the book is awesome. Instead we sennuie lot. This may have been when it was released an important book SF since it lays the foundation of the geostationary satellite and the issue of mass transport people out of the stratosphere. Hard science side and the tool description is boring and history that starts in multiple directions (the science against religion) not naccroche the reader that I am. While I find the dAsimov always exciting novels.
