When a planet, moving faster than Earth, entered the Solar System out beyond Pluto, the reporters, for want of a better name, termed it "Planet X." "Planet X, that astronomical curiosity," became, in a few short weeks, an object of stark terror to the billions of people scattered on the planets around our Sun, from blazing Mercury to frigid Pluto. To Bob Griffith's father, Commander of the Ninth Wing of the Solar Federation's Space Navy, fell the task of investigating the strange visitor whose black ships moved through space without rocket exhaust, and whose weapons literally melted spaceships out of the heavens. As his father's aid, aboard the gleaming LANCE OF DEIMOS that led the reconnaissance fleet, Bob watched in horror the first incident that would start a war which the Solar Federation "could not win." This gripping tale that rockets from Neptune's tiny moon of Outpost, base of the Federation's Navy, to the orbit of an Earth threatened with destruction, features a young space cadet and his father, who, while preparing for war, desperately search for peace. How Bob Griffith finds himself a captive on the mysterious planet, Thule; details of life on a world that has learned how to overcome the forces of gravity and momentum; the discussions that rage over the acceptance of a "wandering planet" into the Solar alliance come alive in a book that vividly creates a troubled era in a fascinating universe of the future!

"Early robot probes sent by Russian and American scientists had given us some tantalizing but fragmentary glimpses of the surface and atmosphere, hinting at some of the most exotic conditions seen in the solar system. Magellan showed a planet full of beautiful landscapes, some eerily familiar and some completely unexpected - a world of active volcanoes, shining mountains, and even river valleys carved by torrents of flowing lava. Venus may once have had a wet, temperate, comfortable climate, much like Earth's. What happened to turn it into a hostile, burning, acid world? Our twin has important tales to tell us regarding several of Earth's most pressing environmental problems, including ozone destruction, global warming, and acid rain. In Venus Revealed, David Grinspoon makes a compelling case for comparative planetology as an important tool for gaining knowledge that is vital for our long-term survival on our own planet. He re-examines the uniqueness of our own Earth in light of the recent Magellan findings, while also raising the provocative questions: Did a runaway greenhouse effect transform Venus into the burning oven she is today? By treating Venus as a "controlled experiment," what can we learn from her that will help us survive on Earth? Grinspoon tackles these and other long-debated questions while explaining the incredible scientific advances made possible by the Magellan space probe."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.
