Starsailing

Louis Friedman, Executive Director of the Planetary Society, presents the first comprehensive look at the science and history behind solar sailing and other designs for space travel. Serious science readers and space buffs alike will be fascinated by designs for the square sail, disk sail, and the heliogyro (which features flexible sails many kilometers long). Friedman compares solar sailing to other proposed propulsion sytems such as ion drives and laser propulsion, and takes an insider's look at the million-dollar JPL project of the late '70s, which was the first attempt at a working model.

The first book to look at rock rebellion through the lens of gender, The Sex Revolts captures the paradox at rock's dark heart--the music is often most thrilling when it is most misogynistic and macho. And, looking at music made by female artists, the authors ask: must it always be this way?

Does one planet really matter among the immensity of the Cosmos? John Gribbin is here to persuade us that it does. In this ground-breaking and provocative new book Gribbin argues that we owe our existence to the impact of a 'supercomet' with Venus 600 million years ago. But this is only part of the story, just one of the astronomical and geophysical reasons why the Earth is special. For the first time, he makes the link between the whole series of cosmic events that have affected the Earth and given rise to our intelligent civilization - a civilization, Gribbin argues, that is unique within our Milky Way Galaxy. Even if other Earths are common, and life itself may be common, the kind of intelligent, technological civilization that has emerged on Earth occurs only here. If humankind can survive the present environmental crises, the whole of the galaxy may become our home. And if not, our demise may be an event of literally universal significance.
