Rating: Summary: A compelling synthesis of sound science and speculation Review: The search for life on Mars has fascinated generations of astronomers and stargazers etc. The announcement that NASA scientists may have located evidence of liquid water on the surface of the red planet is only the latest chapter in the exploration of Mars. As much as the public craves proof of little green men, the focus of the scientific search has been to uncover evidence of the conditions necessary for life. NASA researchers described their approach as "follow the water". Water is critical for the development of life and if the presence of liquid water - at or near the surface of Mars - can be confirmed, scientists will be steps closer to piecing the life-on-Mars puzzle. Mars is the fourth major planet from the Sun, named after the Roman god of war because of its reddish colour. Mars has an elliptical orbit, and so its distance from the Earth varies considerably. Its mean distance from the Sun is 228 million km, about half as far again as is the Earth. A Martian day, or sol, is 24.6 Earth hours, and the Martian year is approximately 687 Earth days. The planet has two small satellites, Phobos and Deimos. Like the Earth, Mars has seasons because of an oblique axis of rotation and the presence of an atmosphere. It is, however, much colder: the mean surface atmospheric temperature is only -23o C. Mars is a small planet, having a mean diameter of 6,790 km, approximately half that of the Earth. Also, its density, 3.933 grams per cubic centimetre, is lower than that of Earth. Mars' thin atmosphere is composed predominantly of carbon dioxide, with some nitrogen and argon. Traces of water vapour have also been detected. The perennial part of the ice caps consists of water ice and the seasonal parts of frozen carbon dioxide. Water is a substance composed of the chemical elements hydrogen and oxygen and existing in gaseous, liquid, and solid states. Water is one of the most plentiful and essential of compounds. It is vital to life, participating in virtually every process that occurs in plants and animals. Water is a colourless, tasteless, and odourless liquid at room temperature. It's able to dissolve many other substances. The versatility of water as a solvent is essential to living organisms. In this book, Hancock states that there's an intriguing possibility that ancient Martian has been communicating with our ancestors and points out that there maybe a connection bewteen the remarkable structures of Egypt, say for example, sphinxs and those of Mars. And if we prove that there once has been water on Mars, will Earth have the same fate, or else we can protect the Earth from extinction? The book is written in a precise and neat way. Very interesting and exiciting.
Rating: Summary: Hanchock has written better Review: This book doesn't give any real answer to the Mars mystery, but still an ok book to read.

Rating: Summary: interesting, better than I thought Review: While the chance for finding intelligent life in the universe is extrememly unlikely (See "Rare Earth" and "Nature's Destiny") the "objects" on Mars always have intriqued me. Hancock does a good review of Mars exploration and what we know of Mars. He also shows us some of the political mess that often runs NASA (See "Deep Time" for another good story on NASA bureacracy concerning the Cassini probe). He scours all previous works on the Cydonia images and pulls it all together, no need to read the older books. The latest MGS photos have caused more problems, than answering questions. NASA photo mishandling and new objects found and questionable photo processing have driven this controversy further. Mars was once wet, and it wouldn't be surprising to find fossils of primitive life, or maybe life there now. Intelligent life is unlikely, but perhaps not impossible. NASA should end its hypocracy, and dedicate some time with these probes to studying the Cydonia region, to answer the lingering questions. The only odd thing proposed in this book, is the continuing search for some "lost civilization." Many cultures share the story of a massive flood in the Middle East having disasterous effects on mankind, which has shown to be rooted in reality (See the book "Noah's Flood). But what evidence of some super-advanced civilization before then? Are similar monument designs around the world inherited from some super race or Martians, or the logical ends of ancient peoples whom relied on the same stars and math for calendars and agriculture?
