Buzz Aldrin was not the first man to walk on the Moon, but wasn't short from Neil Armstrong in making history. This book is a collection of ideas he had gathered with the help of hundreds of specialists he discussed with throughout the years since he came back from the Moon. These ideas are focused on achieving and sustaining trips to Mars on a regular basis and how to further explore the cosmos.
Several outstanding ideas that will make you think, very good, pleasant, and quick read. Highly recommend for anyone who have any interest in space exploration.
