Review
..."a book which should fascinate and stimulate the next generation of physics students. Written with an almost naive simplicity, yet back up at every stage with an explanation of the basic physics and technology. Allday examines not only how NASA reached the Moon in 1969, but the viability of all the subsequent proposals for continuing the journey on to Mars and beyond. He explains with startling clarity that manned bases on mars, which has a similar day/night cycle to Earth's are much more practical than on the Moon." -Astronomy Now "Written in a friendly and informal style, this very readable book will serve as an excellent introduction to astronautics for teenagers/school students interested in space, science teachers and general science readers. All school libraries should have a copy of this book." Spaceflight "An ideal summary of NASA's Apollo program and a good spaceflight primer. Highly recommended." W.E.Howard III, Universities Space Research Association .." all handled very nicely and the text is spiced with real-world examples and illustrated with clear diagrams and black-and-white photos."

Neil's review said it all, if you are into Apollo and/or the space shuttle, this book is a must read. Some of the most interesting information is contained in the six "intermission(s)" at the end of some of the chapters. "Intermission 4: The three 'ings,'" "Eating," "Sleeping," and "Excreting" is priceless.The last Chapter 9- "Journeys to the stars" is a little far fetched, as using current technology it would take about 80,000 years to get to the nearest star.As I commented on the Pioneer space plaque:Having said that, the speed of the Voyager space probes (not the Pioneer discussed above) is about 35,000 miles per hour, or about 51,000 feet per second. We will use this as an example for the Pioneer probes, see below. About 51,000 feet per second is much, much "faster than a speeding bullet," which can range from about 800 feet per second to about 2,000+ feet per second.The nearest stars to Earth are Alpha Centauri (a binary star) and Proxima Centauri, which are about 4.2 light years away. At the speed of the Voyager space probes it would take about 80,000 years to reach Alpha Centauri (From "The Cambridge Atlas of Astronomy," Third Edition, 1994, page 416-417, chapter called "The extraterrestrial life debate.) (Note: the wikipedia.org entry for Pioneer 10 has different information: "At its current speed, 26,900 m.p.h., it will be more distant than the red dwarf Proxima Centauri in 26,118 years." I can not understand this huge difference in projected times between the "The Cambridge Atlas of Astronomy" page 417and this wikipedia entry.)This gives you some idea how large our Galaxy, the Milky Way is. The Milky Way, contains between 100 to 300 billion stars and is about 100,000 light years across. There are about 100 billion galaxies in our Universe. The point is there are many, many stars and a lot of "space" out there and the distances are "astronomical."For reference, the speed of light is about 186,000 miles per second.
I have read most common (and many uncommon) books on the Apollo program. "Apollo in Perspective" is totally unique among all those books. The book is written with a historical perspective on the Apollo program that not only discusses the technology, missions, and hardware of Apollo, it also discusses the political underpinnings of Apollo as well. That is all relatively common, though; the thing that sets this book apart is that it also covers the physics of rockets, orbital mechanics, and trajectories in a comprehensible manner that most casual readers have not been exposed to. He also gives excellent summaries of the Apollo 1 fire and the Challenger accident, as well as observations on the shuttle, future planetary exploration, and John Glenn's shuttle ride.The book is interesting for both aerospace professionals and newly interested readers as well. In the body of the book, for instance, he discusses the basic math behind Newton's laws and required thrust (which accompanies an especially well written section on staging) without resorting to extravagant mathematical proofs, however for the more avid reader he defines the calculus based proofs in the appendix. This writing technique makes the book an excellent choice for an intelligent non-expert to read as an introduction to the Apollo program.I found this book to be quite accurate, and found his conclusions to be generally very sound. I don't universally agree with every opinion he shares in the concluding part of the book (he essentially contends, for instance, that John Glenn's shuttle flight was apolitical, an opinion I don't share, and in which he is definitely in a tiny minority), but I find his reasoning to be excellent overall. My one critique of the book would be that the last third or so of the book dwells on the shuttle, Mars missions, and other future programs (some of which are very far out.) I am sure that Mr. Allday would say that past is prologue, and that those programs form part of the perspective mentioned in his title. I don't dislike the information; I just found some of it less than germane to the Apollo program.This is an excellent, accurate, and interesting book, which I highly recommend to any space enthusiast.
Subtitled "Spaceflight Then and Now", this hardcover book weighs in at 320 pages. And what a surprise. An internet friend suggested I buy this book just to read chapters 5 (The Apollo Command and Service Modules) and 6 (The Lunar Module) but I decided to read the whole thing because it is a treasure trove of information. Here are the chapter names with a few comments thrown in:1) Apollo in Outline2) The Best Driver in Physics (Momentum, Rocket Motor Physics, etc.)x) Intermission 1: The Saturn V booster rocket3) Rocketry (Thrust, Impulse, Real Rocket Engines, etc.)x) Intermission 2: From Mercury to Gemini4) Orbits and Trajectories (Centripetal Forces, Gravity and Orbits, Elliptical Orbits, Circularization Burns and when to do them, Hohmann transfers), Flying to the Moon, Trajectories to Mars (includes why a lower delta-V is required to get to Mars than than to the Moon), Space Stations)5) The Apollo Command and Service Modulesx) Intermission 3: Inertial Guidance and Computers6) The Lunar Modulex) Intermission 4: The Three 'ings' (Eating, Sleeping, Excreting)7) The Shuttle and its Followersx) Intermission 5: The Politics of Apollo8) Marsx) Intermission 6: Godspeed John Glenn9) Journeys to the Stars (Orion and project Daedalus, Laser propulsion, Ramjet, Antimatter Drive, Colony ships, Wormholes, etc.)x) Appendix 1: Glossaryx) Appendix 2: Apollo Mission Summaryx) Appendix 3: Development of Boostersx) Appendix 4: Deriving Some of the Mathsx) Appendix 5: Further Informationx) Index
