Customer Reviews

Very fun book, but somewhat lacking in depth

Michael Hanlon has written a book which captures the excitement of getting Galileo to Jupiter. This includes lots of engineering and management fixes to keep things on track, as well as the euphoria when everything finally works, esp. with the atmospheric probe and the Jupiter orbital insertion. He also describes very well the neat science learned while in orbit, esp. the Europa ocean debate.My only problem with the book is that it's kind of at the PR-level of knowledge. That is, if you were following along with the mission, then there's probably not a lot new to learn here. (If you weren't following along, then feel free to disregard this review! :-) There are some interesting new tidbits, like the proposed work on an underground lake in Antarctica, to prepare for a drilling mission on Europa.

Troubled travels

Journeys of exploration have always been risky ventures. When the trip involves several years over millions of kilometres, the odds of unblemished success grow enormous. Engaging in such a venture in the realm of space, almost beyond the reach of human control suggests hazards beyond imagining. This book describes such a venture, perhaps the most ambitious ever undertaken. That the measure of success achieved was so great is a tribute to all those who planned and implemented it. Michael Hanlon gives us a ringside seat in his portrayal of the journey of the Galileo Mission to Jupiter. Although not a participant, he ably captures the dedication and skills of the Mission Team. Further, he's able to place us in the space vehicle as it traversed one of the most bizarre journeys ever undertaken.The Galileo Mission was spurred by the preceding Pioneer and Voyager missions of the 1970s. These four robots cruised through the outer solar system, returning stunning views of the largest planet and its associates beyond. In doing so, they raised numerous and unanswerable questions about our neighbours in space. Unlike the previous probes, Hanlon takes us through the planning that led Galileo's flight to Venus, back past Earth to its final destination far out in the solar system. The efforts put into the flight brought Galileo to within 5 km of its intended position when it arrived at Venus - a staggering achievement.All the planning and engineering couldn't prevent problems, however. NASA's attempt to open the main transmitting antenna failed when some minor pins failed to release. When Galileo arrived at its primary destination, the antenna looked like an umbrella wracked by high winds. NASA used other methods to maintain communication, resulting in the stunning images seen here. It was a frustrating experience for the mission team, yet Galileo added a treasure house of new information about our neighbours in space.We are so accustomed to the notion that we are the sole home of life, that the problems surrounding Galileo's termination render this issue the most bizarre of the trip. Europa, the ice-coated satellite of Jupiter, may contain living organisms in its hidden sea. In order not to contaminate that life, if it exists, Galileo had to be purposely sacrificed. Hanlon describes the options and why each was considered worthwhile. Galileo went to explore the Jovian system and was still transmitting images as he completed this vividly descriptive work. He is to be commended for a gripping account. We may be the only life in this group of planets, but Galileo's records give us a major argument to continue our search for life elsewhere.

Excellent!

In `The Worlds of Galileo', Mike Hanlon, one of Britain's leading newspaper science editors, relates how NASA's Galileo spacecraft overcame a series of severe problems and went on to revolutionise our understanding of the Jovian system. Drawing upon interviews with the key participants, Hanlon explains the project's origin in the cash-strapped 1970s, the political travails of the early 1980s, and the redesign in the aftermath of the Challenger accident. After the spacecraft's epic voyage out to Jupiter, he focuses upon the astonishing `fire and ice' moons of volcanic Io and Europa, where there appears to be an ocean beneath a thin shell of ice. Hanlon handles the geological discussion with ease, so this is a highly readable account. Certainly, Sir Arthur C. Clarke, who contributed the foreword, was impressed. Finally, St Martins Press is to be congratulated for having produced a very handsome volume with colour imagery throughout.
