As a Rocket Scientist, I have worked on many research papers and textbooks, and they are sold across the world. I have especially worked on interstellar travel techniques and if you go to my website, you can see and read many of the research that I have worked on. However, I believe that the most important challenge ahead of us is exploring our solar system. I already have written books for several destinations in the solar system including Moon, Mars, Jupiter, and Europa. This book is the continuation of my Solar System series as it focuses on a mission to Neptune. In a way, Neptune is an interesting destination and unlocking the secrets of Neptune can pave the way for a greater understanding of our solar system and Earth. Neptune is an ice giant and its atmosphere made of hydrogen, helium with methane gives a special blue color to it. It's one of the most windiest planets in the solar system with winds having speeds over 2000 km/h. and it's the only planet that can't be seen with the naked eye. It is the coldest planet in the solar system and interestingly like Saturn it contains rings though they are not as prominent. I dedicate this book to pioneers of space Sergei Korolev and Werner von Braun who made space travel possible. Prof. Dr. Ugur GUVEN www.drguven.com
